    [001] This request claims priority for and the benefit of the North American provisional order Serial No. 61/794 914 entitled “SYSTEM AND METHOD FOR BALING AGRICULTURAL HARVESTING MATERIAL” deposited on March 15, 21013, which is incorporated by it as a reference. Background of the Invention
    [002] The present invention relates in general to the field of packaging compressible materials and, more specifically, to systems and methods for baling agricultural harvest materials.
    [003] Generally, balers are used to compress certain materials into rectangular bales, in order to facilitate the storage and handling of the material. Typically the material is compressed inside a baling chamber until the material forms a bale of the desired size. Such balers typically include a mechanism for wrapping and tying string around the material in order to maintain the compressed shape of the bale. Unfortunately, the string can be difficult to remove from the bale and can deteriorate the baled material. In addition, the tensile strength of the string may be too low to effectively bind compressed materials in certain applications. SUMMARY OF THE INVENTION
    [004] Certain coextensive modalities in scope with the originally claimed invention are summarized below. These modalities are not intended to limit the scope of the claimed invention, but, instead, these modalities are only intended to provide a brief summary of possible forms of the invention. In fact, the invention can encompass several forms that may be similar to or different from the modalities presented below.
    [005] In one modality, an agricultural baler is presented, arranged in a mobile agricultural implement. The baler includes a first plunger and a second plunger positioned at the opposite longitudinal end of a baling chamber from the first plunger. The baler also includes a belt feed set and a rail set. The rail assembly is arranged within a first slot formed on a first surface facing the material of the first plunger, a second slot formed on a second surface facing the material of the second plunger, a third slot formed on a third surface facing the material of a first wall of the baling chamber, and a fourth slot formed on a fourth surface facing the material of a second wall of the baling chamber, where the first and second walls are positioned on opposite sides or vertical sides the baling chamber. The first plunger is configured to compress the material inside the bale chamber in the form of a bale, and the belt feed assembly is configured to propel one end of a belt through the trough assembly around the bale chamber. and into a coded seal assembly for attaching a first part of the strap to a second part of the strap in order to seal the strap in a loop around the bale within the bale chamber.
    [006] In another modality, an agricultural baler is arranged in a mobile agricultural implement, and the baler includes a baling chamber configured to receive the compressible material. The baling chamber includes a first wall opposite a second wall, wherein each of the first wall and second wall comprises a slot that extends along the length of the baling chamber. A first plunger capable of moving inside the baling chamber is presented to compress the compressible material into a bale. In addition, a second surface opposite the first plunger is provided to support the compressible material within the baling chamber. Each of the first plunger and the second surface comprises a slot aligned with the slits of the first and second walls. A rail assembly comprising a gate connected channel is disposed within the slits of the first wall, the second wall, the first plunger and the second surface so that the rail assembly substantially surrounds the baling chamber.
    [007] In another modality, a method is presented for baling the agricultural harvest material. The method includes collecting the agricultural harvest material in a baling chamber arranged on a mobile agricultural implement and compressing the agricultural harvest material into a bale by means of a first plunger. The method also includes controlling the density of the agricultural harvest material by means of a second plunger positioned opposite the first plunger and feeding one end of a belt into a channel of a rail assembly that surrounds the storage chamber. baling after the agricultural harvest material is compressed in the form of the bale. The method also includes propelling the end of the strap through the channel of the rail assembly, directing the end of the strap into a seal assembly and sealing the end of the strap to a second position of the strap within the seal assembly so to form a sealed loop that surrounds the material.

    [023] One or more specific modalities of the present disclosure will be described below. In an effort to provide a concise description of these modalities, all the features of an actual implementation may not be described in the report. It should be understood that, in the development of any real implementation such as, as in any engineering design project, numerous specific implementation decisions must be made to achieve the specific objectives of the developers, such as compliance with system-related restrictions and related and commercial, which may vary from one implementation to another. Furthermore, it should be understood that such a development effort can be complex and time-consuming, but it would, however, be a routine design and manufacturing endeavor for those skilled in the art who have the benefit of this disclosure.
    [024] When introducing elements of different modalities of the present revelation, the articles “one / one”, “the one / as / as” intend to mean that to one or more of the elements. The terms "who understands", "who includes", and "who have" are intended to be inclusive and mean that there may be additional elements other than the listed elements. Any examples of operational parameters and / or environmental conditions are not exclusive to other parameters / conditions of the revealed modalities.
    [025] The modalities described herein refer to systems and methods for producing a bale of desired size and / or density and for wrapping the bale with a relatively high strength belt. In particular, a first plunger (a front plunger, for example) is configured to compress the material inside the baling chamber of a baler. The front plunger and / or a second plunger (a rear plunger, for example) are configured to precisely control the bale density. In addition, several components can be installed inside the baler to effectively surround the bale with the belt and to securely seal the belt around the bale. The described modalities can have certain advantages over traditional baling systems. For example, the posterior plunger can facilitate the formation of a bale of specific size and / or density, and in some cases, the posterior plunger can allow the formation of relatively high density bales. In addition, the high strength and / or the large surface area of the belt may allow the belt to keep the bale in the desired size and conformation more effectively than the string, thus facilitating easy storage and handling of the bale. In addition, unlike string, the belt can be easily removed from the bale and can reduce the deterioration of the baled material. In addition, certain components described here (such as, for example, a rail assembly) may allow for effective bale wrapping of the bale by substantially reducing or eliminating the twisting of the webbing as the webbing is applied to and sealed around the burden.
    [026] Figure 1 is a perspective view of an embodiment of a baler part 10 configured to form and wrap rectangular bales of material (such as, for example, harvest materials such as hay, straw , grass, forage, corn stalks, tobacco, cotton, biomass, etc.). In the mode shown, the baler 10 includes a frame 12 that defines a baling chamber 14. The baling chamber 14 includes a first end 16 (front end, for example) and a second end 18 (rear end, for example) example) that can generally refer to the direction of travel of the baler 10. For example, the baler 10 can be coupled to a towing vehicle and pulled through a field, collecting and baling the harvest material as that baler 10 moves across the field. When connecting to the towing vehicle, the front end 16 is proximal to the vehicle, while the rear end 18 is distal from the vehicle. The baler 10 can also be included in a self-propelled chassis or it can be part of an independent vehicle. The baler 10 can also be defined as having a lateral geometrical axis 20, a longitudinal geometric axis 22 and a vertical geometric axis 24. Although the embodiment shown includes a horizontal rectangular baler 10, it should be understood that the systems disclosed herein can be readily adapted for use in other types of bale presses, such as vertical bale presses. In addition, although the embodiment shown includes a baler 10 configured to connect the bale around the lateral axis 20, in other ways the baler 10 can be configured to connect the bale around the longitudinal axis 22 or the geometric axis vertical 24. In the baler 10 of Figure 1, the material is compressed inside the baling chamber 14 by a front plunger 26. In the embodiment shown, the front plunger 26 includes a surface facing material 28 that has several parallel slits 30 open for the baling chamber 14. As shown, the bales 30 extend from a first end 32 (top end, for example) of the front plunger 26 to a second end 34 (base end, for example) of the plunger front 26, and the bales 30 are generally aligned with the vertical geometric axis 24 of the baler 10. The bales 30 are spaced evenly across each other across the surface facing the material 28 of the front plunger 26. As shown, six slits are presented on the surface facing material 28 of the front plunger 26, although two, three, four, five, seven, eight, nine, ten or more slits can be presented in other modalities. The front plunger 26 is configured to move axially within the baling chamber 14 in a back and forth motion along the longitudinal geometric axis 22 of the baler. In other words, the front plunger 26 is configured to move in a first direction (forward or forward direction, for example) and in a second direction (reverse or backward direction, for example). In the shown mode, the front plunger 26 is coupled to an actuator 36 by means of one or more arms 38. The actuator 36 can be a hydraulic cylinder or a pneumatic cylinder, or the actuator 36 can include a piston that drives a steering wheel. to connect a gearbox. The gearbox can, in turn, rotate crank arms which are coupled to the arms 38 to facilitate the movement of the front piston 26. Regardless of its shape, the actuator 36 is configured to control the reciprocating movement of the front piston 26.
    [027] In the mode shown, the baler 10 includes a rear plunger 40 (a density control wall, for example), arranged at or near the rear end 18 of baler 10 and opposite the front plunger 26. As shown in front plunger 40 has a material-facing surface 42 which has several parallel slits 30 open to the baling chamber 14. Slits 30 extend with a first end 44 (top end, for example) of the rear plunger 40 to a second end 46 (base end, for example) of the rear plunger 40, and the slits 30 are generally aligned with the vertical geometric axis 24 of the baler 10. The slits 30 are evenly spaced from each other across the material facing surface 42 of the rear plunger 40. In addition, each slot 30 of the rear plunger 40 is arranged in opposition (aligned with, for example) to a corresponding slot 30 of the front plunger 26. In the mode shown, the rear plunger 40 is configured to control the density of a bale formed within the baling chamber 14 through the use of one or more actuators 48 (such as hydraulic cylinder, pneumatic cylinder, etc.), which are coupled to the rear plunger 40 by means of one or more arms as described in more detail below.
    [028] As shown in Figure 1, the baling chamber 14 also has a first wall 50 (a top wall, for example) and a second wall 52 (a base wall, for example) opposite the first wall 50. In As shown, the first wall 50 and the second wall 52 have several parallel slits 30 open to the baling chamber 14. The slits 30 arranged within the first wall 50 and the second wall 52 extend along the longitudinal geometric axis. end 22 of the baler 10 between the front plunger 26 and the rear plunger 40. The slits 30 disposed within the first wall 50 and the second wall 52 can extend along the length of the baling chamber 14 in order to accommodate the various axial positions of the front plunger 26 and the rear plunger 40, and to align with the slits 30 of the front plunger 26 and the rear plunger 40 even as the plungers 26, 40 move axially (along the axis longitudinal geometric 22, for example) den around the baling chamber 14.
    [029] Furthermore, the slits 30 formed in each of the front plunger 26, rear plunger 40, first wall 50 and second wall 52 are aligned so as to substantially encircle or surround the baling chamber 14. More specifically, each the front plunger 26, rear plunger 40, first wall 50 and second wall 52 have a first slot 30a which aligns with the corresponding slots 30 in the other components to substantially surround the baling chamber 14.
    [030] As noted above, in some embodiments, two, three, four, five, six or more slots 30 can be presented in each of the front plunger 26, rear plunger 40, first wall 50 and second wall 52 and, thus, the baling chamber 14 can be surrounded by two, three, four, five, six or more slits 30. As discussed in more detail below, the slits 30 are aligned to allow a belt to be directed around the chamber - baling 14 to wrap the compressible material within the baling chamber in the form of a bale.
    [031] In the embodiment shown, the baler 10 includes a reel 54 configured to store and provide a strap 56 to strap the material inside the baling chamber 14. In certain embodiments, the reel 54 can be accessible and / or removable to facilitate replacement and / or installation of belt 56. As shown, spool 54 supplies belt 56 to a belt feed assembly 58, which is configured to direct and / or propel belt 56 around the chamber baling 14. For example, the belt feeding set 58 pro-skin the belt through the slits 30 in order to surround the bale with the belt 56. As shown in Figure 1, the baler 10 also includes a sealing set -action 60, which is configured to receive and / or capture the strap 56 and to seal a portion of the strap 56 in another part of the strap 56 so as to form the strap 56 in a sealed loop around the bale.
    [032] In systems that have the seal assembly 60, the gap 30 may be interrupted by the seal assembly 60. In other words, the gap 30 may be substantially surrounding the baling chamber 14, but the gap 30 may not be present at the location of the seal assembly 60. As shown in Figure 1, for example, the seal assembly 60 is adjacent (proximal, for example) to the first wall 50 and thus, the gap 30 is not present within the first wall 50 in the seal assembly location 60. In some embodiments, the seal assembly 60 can align with adjacent parts of the slot 30, allowing the belt 56 to be fed through the seal assembly 60 and into the adjacent part of the slot 30 of so as to encircle the burden. In addition, such a configuration allows the strap 56 to be removed from both the seal assembly 60 and the slits 30 after the strap 56 is sealed around the bale, as described in more detail below.
    [033] In certain embodiments, one or more of the spool 54, the belt feed assembly 58 and the seal assembly 60 are coupled to the frame 12 of the baler 10. In addition, the spool 54, the belt feeding assembly 58 and / or the seal assembly 60 can be arranged proximally to the first wall 50 of the bale chamber 14. Although a spool 54, a belt feed assembly 58 and a seal assembly 60 are shown in Figure 1 for For greater clarity, it should be understood that several sets of these components can be installed inside the baler 10 to surround the bale with several straps 56, in some modalities. As shown in Figure 1, for example, the spool 54, the belt feed assembly 58 and the seal assembly 60 are aligned with the first slot 30a. However, a spool 54, a belt feed assembly 58 and a separate seal assembly 60 can be installed and aligned with each of the slots 30. Thus, several straps 56 can be fed through the slits 30 and sealed around burden, as described in more detail below.
    [034] In addition, as noted above, although the modalities shown show systems for strapping the bale around the side geometric axis 20 of the baler 10, it should be understood that the systems disclosed here can be readily adapted to wrap the bale around the longitudinal geometry axis 22 or the vertical geometry axis 24. To reel the bale of the vertical geometry axis 24, for example, the slits 30 can extend across the surface facing material 28 of the front plunger 26 so that the slits 30 are aligned with the lateral geometric axis 20 of the baler 10 and are parallel to the top end 32 and the base end 34 of the front plunger 26. Likewise, the slits 30 can extend through the material-facing surface 42 of the rear plunger 40 so that the slits 30 are aligned with the side geometric axis 20 of the baler 10 and are parallel to the end of top 44 and the base end 46 of the rear plunger 40. In such configurations, the strap 42 can be propelled through slits 30 in the lateral direction 20 through slits 30 of the front plunger 26 and slits 30 of the rear plunger 40. In addition , in such configurations, instead of the slits 30 being formed in the top wall 50 and the base wall 52, the slits 30 can extend along a first side wall and a first side wall, opposite the first side wall , of the baling chamber 14 between the front plunger 26 and the rear plunger 40. The spool 54, the belt feed assembly 58 and / or the sealing assembly 60 can be arranged on the first side wall of the baling chamber 14 , and the needle 52 can be arranged on the second side wall of the baling chamber 14. The components can work together to surround the bale with the strap 42 around the vertical geometric axis 24 of the baler 10.
    [035] Belt 56 can be formed from any suitable material of relatively high strength. For example, belt 56 can have a resistance of about 150 kilogram-force (kgf) to about 1500 kgf. In some embodiments, the strap 56 may have a strength of about 300 kgf to about 1200 kgf. The strap 56 can be of any suitable, although the strap 56 can be from about 1 centimeter (cm) to about 5 cm wide, in some embodiments. In certain embodiments, the strap 56 may be formed from carbon steel or plastic, such as polypropylene or polyester. In some embodiments, the baler 10 is configured to form bales that are about 2 to about 3 meters long (along the longitudinal geometric axis 22) by about 1 to about 2 meters wide (along the axis lateral geometric 20), by about 0.5 to about 1 meter in height, along the vertical geometric axis 22, and the belt 56 is of adequate strength to securely gird bales of this size.
    [036] Figure 2 is a perspective view of another embodiment of a part of the baler 10 that has the front plunger 26 and a rear wall 62. In certain embodiments, the baler 10 may include a rear wall 62 instead of the rear plunger 40. The rear wall 62 is stationary and includes a surface facing material 64. In the embodiment shown, the surface facing material 64 includes several parallel slits 30 open to the baling chamber 40. Slits 30 extend from a first end 66 (top end, for example) of the rear wall 62 to a second end 68 (base end, for example) of the rear wall 62, and the slits 30 are generally aligned with the vertical geometric axis 24 of the baler . Slits 30 are spaced evenly across the material facing surface 64 of rear wall 62. In addition, each slit 30 of rear wall 62 is arranged in opposition to (aligned with, for example) a corresponding plunger slot front 26. In the modality shown, the rear wall 62 is configured to facilitate the collection of material in the baling chamber 14 and to maintain the bale conformation.
    [037] Figure 3 is a perspective view of an embodiment of the front plunger 26 that has several slits 30 formed under the surface facing material 28 of the front plunger 26. As discussed above, the parallel slits 30 opened to the chamber balers 14 extend from the first end 32 (top end, for example) of the front plunger 26 to the second end 34 (base end, for example) of the front plunger 26, and the slits 30 are generally aligned with the vertical geometric axis 24 of the baler 10. Slots 30 are evenly spaced from each other across the material facing surface of the front plunger 26, although another spacing may be suitable in some embodiments. As shown, six slits are presented on the material facing surface 28 of the front plunger 26, although two, three, four, five, seven, eight, nine, 10 or more slits can be presented in other embodiments. Slots 30 allow the belt 56 to be propelled (directed, for example) around the baling chamber 14 to facilitate wrapping the bale with the belt. The slots 30 arranged in the rear plunger 40 and / or in the rear wall 62 can have a configuration similar to the slits 30 arranged in the front plunger 26 shown in Figure 3.
    [038] Figure 4 is a cross-sectional view of an embodiment of a rail assembly 71 having a door 70 disposed within the slot 30 of the front plunger 26. Although the slot 30 which has the door 70 is shown inside the plunger front 26 in Figure 4, similar doors 70 can be arranged within the slits 30 of the rear plunger 40, the first wall 50 and the second wall 52. In some embodiments, the doors 70 can be lowered a distance 72 into the slot 30 (a from the material-facing surface 28 of the forward piston 26, for example). Lowering door 70 from the surface facing material 28, for example, can allow door 70 to open and close without interference from the material inside the bale chamber 14. Door 70 can generally retain Get the strap 56 into the slot 30 as the strap 56 moves through the slot 30, as described in more detail below. As shown, the door 70 is coupled to the slot 30 by one or more hinges 74, which can be spring loaded, although any suitable material is contemplated to couple the door 70 to the slot 30. In such configurations, after the strap 56 is fed through the slits 30 around the baling chamber 14, the door 70 releases the belt 56 from the slits 30 when a force is applied to the door 70 by the belt 56. For example, the doors 70 can release the belt 56 when the belt 56 it is pulled tightly around the bale (by the belt feed assembly 58 or the seal assembly 60, for example). In some embodiments, the door 70 can be actuated, and the door 70 can be configured to open at a certain time (after the belt is fed through the slits 30 and surrounds the bale inside the baling chamber 14, for example ).
    [039] Figure 5 is a cross-sectional view of another embodiment of an independent rail assembly 80 arranged inside the slot 30. In certain bale press systems 10, it may be desirable to install the rail assembly 80 inside each slot. 30 to receive and direct the belt 56 through the slot 30 and around the baling chamber 14. For example, the rail assembly 80 can be formed from materials (high strength materials, for example) that can be configured to reduce the wear and tear caused by the movement of the belts 56 through the rail assembly 80. The rail assembly 80 can also be re-stopped or replaced if part of the rail assembly 80 becomes worn over time without the need to replace plungers 26, 40 or walls 50, 52, for example. In the embodiment shown, the rail assembly 80 is coupled to the slot 30 and thus the slot 30 supports the rail assembly 80. In certain embodiments, the rail assembly 80 extends from the first end 32 to the second end 34 from the front plunger 26, from the first end 44 to the second end 46 of the rear plunger 40 and along the length of the slits 30 formed within the first wall 50 and the second wall 56. Again, although the slot 30 shown inside the forward plunger 26 in Figure 5, similar rail assemblies 80 can be arranged within the slits 30 of the rear plunger 40, the first wall 50 and the second wall 52.
    [040] As shown in Figure 5, the rail assembly 80 also includes walls 82 that define a channel 84 through which the strap 56 can move. The rail assembly 80 also has a port 86 (the rail assembly 80 may include a channel connected by port 84, for example). Similar to port 70 described above with reference to Figure 4, port 86 is configured to retain strap 56 within channel 84 as strap 56 is propelled through channel 84. In some embodiments, ports 86 can be lowered one distance 88 into slot 30 (from the material facing surface of the front plunger 26, for example). Lowering door 86 from the surface facing material 28, for example, can allow door 86 to open and close without interference from the material inside the bale chamber 14. As shown, door 86 is coupled to the mesh 82 by one or more hinges 90 that can be spring loaded. In such cases, after belt 56 is fed through channel 84 around baling chamber 14, port 86 releases belt 56 from channel 84 when a force is applied to port 90 by belt 56. For example, doors 86 can release the belt 56 when the belt 56 is pulled tightly around the bale (by the belt feed assembly 58 or the seal assembly 60, for example). In some fashion, door 86 can be actuated, and door 86 can be configured to open at a certain time (after belt 56 is fed through channel 84 and surrounds the bale inside the bale chamber 14 , for example).
    [041] Figure 6 is a cross-sectional side view of a baling chamber modality 14 that has the rail assembly 80 arranged around the baling chamber 14 and a belt feeding assembly 58 arranged in front of a sealing assembly 60. The front plunger 26 is disposed at the front end 16 of the baling chamber 14, while the rear plunger 40 is disposed at the rear end 18 of the baling chamber 14, opposite the front plunger 26. The first wall 50 and the second wall 52 opposite the first wall 50 extends between the front plunger 26 and the rear plunger 40 along the longitudinal geometrical axis of the baling chamber 14. One or more struts 97 are installed to support the material within the baling chamber 14. The catches generally retain the material within the baling chamber 14 as the front plunger 26 moves forward. The catches 87 can be spring-loaded so that they retract as the front plunger 26 moves backward into the baling chamber 14, passing over the catches 97. The latches can be loosened or moved moves into the baling chamber 14 as the front plunger 26 moves forward out of the baling chamber 14.
    [042] In operation, the compressible material enters the filling chamber 14 through the front end 16. The front plunger 26 then moves in an axial direction (along the longitudinal geometric axis 22, for example) inside the filling chamber. pack 14 in order to propel the compressible material backwards, thus compressing the material against the rear plunger 40. In certain embodiments, the rear plunger 40 is adjustable and content by pressure, and is configured to generally control the size and / or the density of the bale formed in the baling chamber 14. In the mode shown, the rear plunger 40 is configured to control the bale density by means of actuator 48 (such as, for example, hydraulic cylinder, pneumatic cylinder, etc.) , which is communicated to the rear plunger 40 by an arm 98. In some embodiments, the desired gap density can be achieved by setting a relief valve 100 at a pre-fixed limit pressure that corresponds to the desired bale density, for example. Once the desired density has been obtained, the baler 10 can automatically initiate the belt fastening process, in which the belt feed assembly 58 drives the belt 56 into the slits 30 to encircle the bale.
    [043] In certain embodiments, the rear plunger 40 can be positioned close to (close to, for example) front plunger 26 before the bale is formed and in preparation for receiving the material in the baling chamber 14. For example, the rear plunger 40 can move in the direction of front plunger 26 along a path 101, which is configured to facilitate movement of the rear plunger 40 within the baling chamber 14. In certain embodiments, path 101 can coincide with slot 30 or track assembly 71, 80. The rear plunger 40 may have cylinders 102 configured to allow the rear plunger 40 to move (roll, for example) along path 101 within the wrapping chamber 14. The material can flow into the baling chamber 14 and can be pushed back towards and against the rear piston 40 by the front piston 26.
    [044] In some embodiments, when the force applied by the material inside the baling chamber 14 against the rear plunger 40 exceeds the preset limit pressure established by the relief valve 100, the actuator 48 allows the rear plunger 40 to move backwards, as indicated by arrows 22. This results in the establishment of the desired bale density. In the shown mode, a stop 104 is installed to block the rearward movement of the rear piston 40, thus limiting the size of the bale. The stop 104 can be adjustable to allow the formation of bales of varying lengths. For example, the stop 104 can be mechanically and / or electronically adjusted by a baler control system 10. In such a configuration, the operator can adjust the position of the stop 104 (and therefore the length of the bales) by entering a length of desirable burden on the control system, for example. Although shown as a mechanical stop 104 that physically blocks the movement of the rear piston 40 backwards, any other suitable mechanism is contemplated to limit the movement of the rear piston back and control the size of the bale. In such configurations, the strapping process can begin after the rear plunger 40 reaches the stop 104. In some embodiments, the strapping process can start automatically when the rear plunger reaches the stop 104. In addition hence, a sensor (or a series of sensors) can be disposed within the bale press system 10 or the stop 104 can include or form a sensor, to facilitate deactivation of the front piston 26 when the rear piston 40 reaches the stop 104 thus establishing the desired size of the bale.
    [045] In certain embodiments, the rear piston 40 can be coupled to a hydraulic cylinder of great strength that allows the baler 10 to generate bales of relatively higher density. In such configurations, once the rear piston 40 meets the stop 104, the front piston 26 stops moving in the backward direction. Then, the rear plunger 40 is propelled forward in the direction of the front plunger 26 by means of the high-strength hydraulic cylinder to further compress the bale and to obtain a higher / lower density bale. For example, stop 104 can be fixed so that the rear plunger 40 is moved backwards to generate a 3.04 m (10 ft) bale. Once the length of 3.04 m (10 feet) has been obtained, the front plunger 26 stops and the rear plunger 40 then moves forward (0.304 m (one foot), 0.60 m (two feet), 0.91 m (three feet) or more, for example) by means of the high-strength hydraulic cylinder in order to shorten the bale length in the direction of the longitudinal geometric axis 22, for example) of the bale inside the bale chamber 14, producing thus a denser / smaller burden.
    [046] As discussed above, baler 10 includes several components configured to make it easy to strap the compressible material within the baling chamber 14. Such components include the belt feed assembly 58 and the seal assembly 60, for example. These components can be placed in different positions with respect to the baling chamber 14 and with respect to each other. As shown in Figure 6, for example, both the belt feed assembly 58 and the seal assembly 60 are arranged on a first side 106 of the baling chamber 54 (as, for example, proximal to the first wall 50, above of the baling chamber 14, etc.). As shown in Figure 6, the belt feed assembly 58 is arranged in front of the seal assembly 60 (such as, for example, the belt assembly 58 is proximal to the front end of the baling chamber 14 and the assembly seal 60 is distal from the front end 16). In such a configuration, the belt feed assembly 58 feeds (such as, directs, propels, etc.) an end 108 of the belt 56 into a mandrel 110 of the seal assembly 60, as shown by arrow 112. From the seal assembly 60, the end 108 of the strap 56 is directed into the slot 30 (or the rail assembly 80 disposed within the slot 30) of the first wall 50. Once inside the slot 30, the end 108 the belt 56 is propelled towards the rear piston 40 disposed at the rear end 18 of the baling chamber 14, as shown by arrows 114. The end 108 of the belt 56 then moves through the slot 30 aligned with the rear piston 40, from the second wall 52 and front plunger 26. After moving around the baling chamber 14, the end 108 of the strap 56 is directed once more into the mandrel 110 of the seal assembly 60. In some embodiments, the seal assembly 60 may include one if sensor and a retainer, and when the sensor detects the presence of the strap 56, the retainer can retain or capture the strap 56. Once the end 108 of the strap 56 is received, the seal assembly 60 can seal the end 108 of the strap 56 on part of the strap 56 arranged within the seal assembly 60 so as to form the strap 56 in a closed loop around the bale within the bale chamber 14. The seal assembly 60 may use any technique suitable for seal the belt 56, such as friction welding. In addition, in certain embodiments, the belt feed assembly 58 is configured to exert a push (push back, for example) the belt 56 in the direction of arrow 116 until a certain tension (pre-established, for example) is obtained before sealing the strap 56. In some embodiments, the sealing assembly 60 may also cut the strap 56 in preparation for strapping another bale.
    [047] In certain embodiments, however, it may be desirable to install the belt feed assembly 58 behind the seal assembly 60 (belt assembly 58 is proximal to the rear end 18 of the bore chamber 14 and the assembly sealing ring 60 is distal from the rear end 18, for example). Accordingly, Figure 7 is a cross-sectional side view of a baling chamber embodiment 14 that has the rail assembly 80 arranged around the baling chamber 14 and the belt feeding assembly 58 disposed behind the assembly. seal 60. In such a configuration, the belt feed assembly 58 feeds the end 108 of the belt 56 in a generally forward direction, as shown by arrow 120, into the mandrel 110 of the seal assembly 60. From the seal assembly 60 , the end 108 of the strap 56 is directed into slot 30 (or from calculating 80 into slot 30) of first wall 50 or directly into slot 30 of front plunger 26, depending on the relative location of the seal assembly 60. Once inside the slot 30, the end 108 of the strap 56 is propelled through the slots 30 of the front plunger 26, the second wall 52, the rear plunger 40 and the first wall 50, as shown by arrows 122. After moving around the baling chamber 14, the end 108 of the strap 56 is directed back into the mandrel 110 of the seal assembly. As noted above, in some embodiments, the seal assembly 60 may include a sensor and a retainer and when the sensor detects the presence of the strap 56, the retainer retains or captures the strap 56. Since the end 108 of the strap 56 is received, the seal assembly 60 may seal the end 108 of the strap 56 in a portion of the strap 56 arranged within the seal assembly 60 so as to form the strap 56 in a closed loop around the bale within the packing chamber. baling 14. In addition, in certain modalities the belt feeding set 58 is configured to exert a thrust (for example, to pull back) on the belt 56, as shown by arrow 124, until a certain tension (pre- established, for example) is obtained before the sealing of the strap 56. In some embodiments, the sealing assembly 60 may also cut the strap 56 in preparation for strapping another bale. After the belt 56 is sealed around the bale, the bale is removed (moved, ejected, caused to fall, for example) from the bale chamber 14. Any suitable mechanism for removing the bale is contemplated. In addition, the ejection systems and methods described herein can be used in conjunction with various containment systems and methods, in addition to the systems for bracing the burden described above. For example, ejection systems can be used with alternative strapping systems, stringing systems or other containment systems. In addition, ejection systems can be used to remove bales that are surrounded by belt 56, string or other materials.
    [048] Figure 8 is a perspective view of a baler modality 10 that has an ejection system 130. As shown, the bale ejection system 130 includes a hinge 132 near the front end 16 of the chamber baling 14. The hinge 132 is coupled to the frame 12 and the second wall 52. Consequently, the second wall 52 is hinged at the first end 16 of the baling chamber 14. The second wall 52 hinges (rotates, for example ) around hinge 132 and around a hinge axis 133, which extends through hinge 132 and can be parallel to the lateral hinge axis 20. The movement of the second wall 52 facilitates the removal (ejection, for example) of the bundle chamber burden 14.
    [049] Figure 9 is a cross-sectional side view of a baler modality 10 that has the ejection system 130, in which the second wall 52 is able to move (as, for example, able to articulate , capable of rotating, etc.) from a first position 134 to a second position 136. For example, the second wall 52 of the baling chamber 14 can be configured to pivot (rotate, for example) around hinge 132 in the direction 138 from the first position 134 (a position generally horizontal, for example) to the second position 136 (a position generally sloped down, for example). In the first position 134, the second wall 52 supports the bale, the orientation of the second wall 52 in the second position allows the bale to move (such as sliding, lowering, etc.) down along the second wall in a direction 139 until the bale leaves the baling chamber 14. The angle of rotation of the second wall 52 around the hinge 132 may vary, although in some embodiments, the second wall 52 can rotate so that an opening 140 formed in the second end 18 of baler 10 has a length 143 along vertical vertical axis 24 from about 0.5 meter to about 2 meters. In addition, the second wall 52 can rotate so that the bale can move freely and / or readily (slide, for example) out of the baling chamber 14 without being driven in direction 139 (without applying a force that has components in place) along the longitudinal geometric axis 22 and / or along the vertical geometric axis 24, for example). In certain embodiments, however, a conveyor 141 (such as, for example, belt, rail, chain, etc.) is disposed on the base wall 52 to facilitate the removal of the bale from the baling chamber. The conveyor 141 may have a woven surface 142 (such as projections, struts, etc.) configured to contact the bale and to facilitate the removal of the bale from the baling chamber 14. During or after the wall movement base 52 to the second position 134, the conveyor 141 can propel the bale towards the second end 143 of the base wall 52, thereby pulling the bale out of the bale chamber 14 in direction 139.
    [050] In addition, the second wall 52 of the baler 10 can be configured to automatically pivot around hinge 132 after the bale is strapped (after the strap 156 is sealed around the bale by the assembly seal 60, for example). For example, a control system can orient the second wall 52 so that it hinges around hinge 132 after the bale is strapped. In other embodiments, the second wall 52 can be configured to pivot around hinge 132 in response to an entrance (an operator entrance, for example).
    [051] Figure 10 is a side cross-sectional view of a baler modality 10 that includes the ejection system 130. As shown, the ejection system 130 includes a meat 145, or meat type mechanism, configured to move a first sidewall 148 and / or a second sidewall 150 out of the baling chamber 14. In certain embodiments, the first sidewall 146 and / or the second sidewall 148 is movable, and each sidewall 148 150 is coupled to one or more meats 145 (a first meat 145a is coupled to the first side wall and / or a second meat 145b is coupled to the second side wall 148, for example). However, it should be understood that other components for moving the first sidewall 146 and / or the second sidewall 148 can be used in alternative embodiments. For example, in some embodiments, the first sidewall 146 and / or the second sidewall 148 can be coupled to an actuator (such as, for example, a hydraulic cylinder, a pneumatic cylinder, etc.) configured to drive the respective sidewall 146, 148 out of the baling chamber 14.
    [052] As shown in Figure 10, the meat 145 is configured to facilitate the movement of the first sidewall 146 and / or the second sidewall 148 away from the baling chamber 14 (and / or away from the second wall 52 and / or away from the bale inside the baling chamber 14). The meat 145 is configured to rotate, and the rotation of the meat 145 drives the side walls 146, 148 away from the baling chamber 14. The meat 145 can be driven to rotate by an actuator (a hydraulic cylinder, a pneumatic cylinder or a mechanical articulation, for example).
    [053] In certain embodiments, the meat 145 can drive the first sidewall 146 and / or the second sidewall 148 to move out of the baling chamber 14 along the lateral geometric axis 20. In certain embodiments, the first sidewall 146 and / or the second sidewall 148 move vertically away from the baling chamber 14 along the vertical geometric axis 24. In other embodiments, the first sidewall 146 and / or the second sidewall 148 move sideways and vertically (the movement of the first sidewall 146 and the second sidewall 148 may have a component in the lateral direction 20 and vertical direction 24, for example) away from the baling chamber 14.
    [054] In general, moving the first sidewall 146 and / or the second sidewall 148 away from the baling chamber 14 allows the bale to move out of the baling chamber 14. For example, the first sidewall 146 and / or the second side wall 148 supports at least a part of the bale within the baling chamber 14 (by means of support or friction contact, for example). Therefore, moving the side walls 146, 148 away from the bale chamber 14 reduces friction on the bale and allows the bale to slide along the second wall 52 angled down out of the bale chamber 14.
    [055] In addition, or alternatively, moving the first side wall 146 and / or the second side wall 148 away from the baling chamber 14 allows the second wall 52 to rotate around hinge 132, thus allowing removal of the bale. For example, the first side wall 146 and / or the second side wall 148 can support the second wall 52 (by means of an engagement mechanism or support structure that is coupled to the side walls 146, 148 with the second wall 52, for example) . Therefore, moving the first side wall 146 and / or the second side wall 148 away from the baling chamber 14 releases the support provided by the side walls 146, 148 and allows the second wall 52 to rotate around hinge 132. In the embodiment shown, the meats 145 are configured to move the first side wall 146 and the second side wall 148 in opposite directions along the side geometry axis 20, thus driving the side walls 146, 148 away from the bale chamber 14, as shown by the arrows 152. In some embodiments, the first sidewall 146 and the second sidewall 148 are moved simultaneously.
    [056] Figure 11 is a side cross-sectional view of a baler modality 10 that has an ejection system 160. As described above, with respect to Figure 6, the rear plunger 40 can be configured to move see within the baling chamber 14 to control the size and / or density of the bale. The rear plunger 40 can move backwards to a final position 162, which can be reached when the rear plunger 40 comes into contact with the stop 104 or another specific or pre-established location relative to the baling chamber 14. After the rear plunger 40 reaches final position 162, if the bale is no longer contained, the bale can then be contained by any suitable mechanism, such as the strapping system described above. The ejection system 160 can then remove the contained bale (strapped, for example) from the bale chamber 14. As shown, the rear plunger 40 hinges around a hinge 164 of a first position 166 (a first position generally vertical, for example) to a second position 168 (a second position generally horizontal, for example). In the first position 166, the rear plunger 40 can support the bale within the baling chamber 14 and, in the second position 168, the rear plunger 14 to allow removal of the bale from the baling chamber 14. The rear plunger 40 can be rotated by through any suitable mechanism. For example, the rear piston 40 can be coupled to an actuator configured to rotate the rear piston 40 around hinge 164 from first position 166 to second position 168.
    [057] In addition, as described above, with respect to Figures 8-10, the rear plunger 40 can be configured to automatically articulate around hinge 164 after the bale is contained (after the belt 56 is sealed around the bale by the seal assembly 60, for example). For example, a control system can orient the rear plunger 40 to pivot around hinge 164 after the bale is strapped. In other embodiments, the rear piston 40 can be configured to pivot around hinge 164 in response to an entry (an operator entry, for example).
    [058] Figure 12 is a cross-sectional side view of another embodiment of the baler 10 that has an ejection system 160. In the embodiment shown, the rear piston 40 is configured to move (such as, for example, rolling, de -locate, etc.) along the path 101 from the first position 166 to the second position 168. The path 101 can be curved or can move from a generally horizontal position 170 to a generally vertical position 172. Thus , when the rear piston 40 reaches the final position 162, the rear piston 40 follows the trajectory 101 and rotates away from the baling chamber 14, thus allowing the bale to exit the baling chamber 14.
    [059] As shown in Figures 11 and 12, the material-facing surface 42 of the rear plunger 40 can be configured to facilitate the removal of the bale. In certain embodiments, a conveyor 174 (belt, rail, chain, etc., for example) is arranged on the material facing surface 42 of the rear plunger 40. The conveyor 174 can be a woven surface 176 (such as, for example, projections, traps, etc.) configured to contact and to facilitate the removal of the bale from the baling chamber 14. During or after movement of the rear plunger 40 to the second position 168, the conveyor 174 can propel the bale in the towards the first end 44 of the rear plunger 40, thus pulling the bale back out of the bale chamber 14, as shown by arrow 178.
    [060] In balers 10 that have one or more stops 104 configured to control the size of the bale, the stops 104 can be configured to recede. Thus, the rear plunger 40 can move backward beyond the stops 104 after the bale is contained, and the rear plunger 40 can pivot around hinge 164 or move along path 101, thereby allowing the bale moves out of the baling chamber 14. Alternatively, the stops 104 may not be mechanical stops 104 and / or may be configured to facilitate rotation of the rear plunger 40 around hinge 164 or to move along the trajectory 101.
    [061] In balers 10 having the ejection system 160 shown in Figures 11 and 12, it may be desirable to have a non-continuous flow of material into the baler 10. For example, the flow of material into the chamber baling 14 can be stopped as the rear plunger hinges and the bale moves out of the baling chamber 14, thereby preventing material (loose material that has not been compressed into the bale, for example) from leaving the chamber baling 14 while the rear plunger 40 is in the second position.
    [062] Figure 13 is a side view of an embodiment of an independent vehicle 190 that includes the baler 10. As shown, the boring chamber 14 is supported and / or mounted within the or on the independent vehicle 190. The material can flow into the baling chamber 14 by means of a transport system, where the material is baled in the manner described above. Thus, the baler 10 can be configured to collect and bundle the material, as the independent vehicle 130 moves through the field.
    [063] Figure 14 is a side view of a modality of a towed implement that has baler 10. As shown, baler 10 includes a baling chamber 14, baler 10 can be held on the ground by 200 and it can be coupled to a towing vehicle (such as, for example, a combine, a tractor, etc.) by a projection 202 which is configured to connect baler 10 to the towing vehicle. Thus, the baler 10 can be part of the implement towed and pulled across the field. In such a configuration, the baler 10 collects and stuffs material as the baler 10 travels across the field behind the towing vehicle.
    [064] Although the invention has been described with respect to a preferred modality, those skilled in the art will understand that several changes can be made and equivalents can replace the elements of it without abandoning the scope of the invention. In addition, many modifications can be made to adapt a specific situation or material to the teachings of the invention without abandoning its essential scope. Therefore, it is intended that the invention is not limited to the specific modality disclosed as the best way contemplated for carrying out this invention, but that the invention includes all modalities that fall within the scope of the appended claims.
