    BACKGROUND OF THE INVENTION Field of the Invention
    [001] The present invention relates to agricultural harvesters and, more particularly, agricultural harvesters with harvesting material elevators. Description of the Related Art
    [002] Combines are used to harvest agricultural crops such as corn, soy beans, wheat and other grain crops. As the harvester is guided by harvest fields, the harvester cuts the crop, separates the desired crop from unwanted waste, stores the crop and discards the waste.
    [003] In a common harvester, a collector is mounted in front of the harvester to gather the crop and feed the crop to the harvester for processing. As the harvester is oriented by the field, the harvest material is collected by the collector and deposited in a feeder housing. Co-harvesting material is then transported up and into the harvester by a feed elevator located inside the feeder housing. The harvest material then passes through a threshing and separating mechanism. In a rotary harvester, the thresher and separator mechanism includes a rotor, a thresher hollow, a rotor cage and a separator harrow. As a harvesting material passes between the rotor, the threshing bowl and the separating harrow, the harvest material is impacted and / or rubbed, which causes the grain to separate from the stalk material. The stem material that is separated from the grain is usually referred to as a different grain material (MOG). Other types of harvesters are also known to perform similar functions using different mechanisms.
    [004] After passing through the thresher and separator set, the grain and MOG are deposited in a grain cleaning system. The grain cleaning system of a common harvester includes a plurality of adjustable cleaning sieves, often referred to as a chopper sieve and an end sieve. Sieves are usually reciprocated back and forth in opposite directions along an arched path. This movement tends to separate the grain from the MOG. To further separate the grain from the MOG, a cleaning fan or blower is positioned so as to blow air through the cleaning screens. This flow of air tends to blow the MOG which is usually lighter than the grain, back and forth from the rear of the combine. The grain, which is heavier than MOG, is allowed to fall through the openings in the sieve.
    [005] The clean grain that falls through the cleaning sieves is deposited in a collection panel positioned below the cleaning sieves. The collection panel is angled to allow the grain to flow, under the influence of gravity, on a auger chute positioned along the lower edge of the collection panel. The auger line is normally positioned near the front end of the cleaning screens and extends along the width of the screens. The grain collected in the auger chute is then moved by a auger towards the side of the combine where it is lifted by a grain elevator and deposited in a storage tank or a grain tank. Other systems also exist that can use, for example, a circuit transport system that eliminates the need for a conventional transverse auger.
    [006] The grain cleaning system is usually the bottleneck that limits the capacity of an agricultural harvester. The bottleneck results from the desire to effectively separate the grain from the MOG, which requires a long enough travel of the grain and MOG through the sieves to separate the grain from the MOG. Simply speeding up the operation of the grain cleaning system is effective in increasing capacity, but it also increases the likelihood that MOG will not be separated from the grain. While other efforts have improved the grain cleaning system included in agricultural harvesters, the grain cleaning system remains the common bottleneck that limits the capacity of the agricultural combine.
    [007] What is needed in the technique is an agricultural harvester with an improved capacity SUMMARY OF THE INVENTION
    [008] The present invention provides an agricultural harvester with a lifter that includes a blower that can produce a pressurized air stream through an air inlet to expel loose crop material in an air outlet.
    [009] The invention in a form is aimed at an agricultural harvester that includes: a chassis; at least one terrestrial hitch member connected to the chassis; a cleaning system maintained by the chassis and configured to clean harvest material; and an elevator provided with the harvest material cleaned by the cleaning system. The elevator includes a housing that has a collection material inlet that receives the collection material, a tank portion that forms a bottom of the housing, an air inlet and an air outlet; a plurality of paddles configured to transport the harvest material through the housing and away from the tank portion in a generally vertical direction; and a blower configured to produce a pressurized air stream through the air inlet that expels harvest material loosened in the air outlet as the harvest material is transported away from the tank portion.
    [010] The invention in another form is directed to a collection material lift that includes: a housing that has a collection material inlet, a tank portion that forms a bottom of the housing, a top, an air inlet and an air outlet; a drive circuit maintained inside the housing extends from the tank portion towards the top of the housing; a plurality of paddles connected to the drive circuit and configured to transport harvest material away from the tank portion towards the top of the housing; and a blower configured to produce a pressurized airflow through the air inlet that expels harvest material loosened in the air outlet as the harvest material is transported away from the tank portion.
    [011] An advantage of the present invention is that it can increase the capacity of the agricultural harvester by removing MOG in the elevator.
    [012] Another advantage is that the elevator can remove MOG from the grain which can do it through the grain cleaning system. BRIEF DESCRIPTION OF THE DRAWINGS

The exemplifications presented in the present document illustrate modalities of the invention and such exemplifications should not be considered as limiting the scope of the invention in any way. DETAILED DESCRIPTION OF THE INVENTION
    [015] The terms "grain", "straw" and "waste" are mainly used throughout this specification for convenience, but it should be understood that these terms are not intended to be limiting. In this way, "grain" refers to that part of the harvest material that is threshed and separated from the disposable part of the harvest material that is termed as a harvest material other than grain, MOG or straw. The harvest material that is incompletely threshed is called "waste". In addition, the terms "forward", "backward", "left" and "right", when used in connection with the combine harvester and / or components thereof, are usually determined with reference to the direction of operational travel front of the combine, but again, they are not built as limiting. The terms "longitudinal" and "transverse" are determined with reference to the retractable directions of the agricultural harvester and must also not be construed as limiting.
    [016] With reference now to the drawings and, more particularly, to Figure 1, an agricultural harvester in the form of a harvester 10 is shown which, in general, includes a chassis 12, ground hitch wheels 14 and 16, a collector 18, a feeder housing 20, an operator's cabin 22, a threshing and separating system 24, a cleaning system 26, a grain tank 28 and an unloading auger 30. It should be understood that, although the agricultural harvester is shown as a harvester 10, the agricultural harvester according to the present invention can be any type of construction that allows harvest material to be harvested, such as a conventional harvester (which does not have a rotor), a rotary harvester, a hybrid harvester, slicer harvester, etc.
    [017] The front wheels 14 are larger floating type wheels and the rear wheels 16 are smaller steerable wheels. Automotive power is selectively applied to the front wheels 14 through a power plant in the form of a diesel engine 32 and a transmission (not shown). Although a harvester 10 is shown as one that includes wheels, it should also be understood that harvester 10 may include caterpillars, such as complete or semi-caterpillar caterpillars.
    [018] The collector 18 is mounted in front of the combine 10 and includes a cutting bar 34 to separate crops from a field during a forward movement of the combine 10. A rotating reel 36 feeds the harvest in the collector 18 and a double auger 38 feeds separate harvest laterally into each side towards the feeder housing 20. Feeder housing 20 transports the cut crop to a thresher and separator system 24 and is selectively movable vertically using suitable actuators such as hydraulic cylinders (not shown) .
    [019] The thresher and separator system 24 is of the axial flow type and, in general, includes a rotor 40 at least partially surrounded by and rotatable within a corresponding perforated cavity 42. The cut crops are threshed and separated by rotation of the rotor 40 within the hollow 42 and larger elements, such as stems, leaves and the like, are discharged from the rear of the harvester 10. Smaller elements of the harvest material that includes grain and different grain harvest material that includes larger particles light that grain, such as chaff, dust and straw, are discharged through the perforations in the concavity 42.
    [020] The grain that was separated by the thresher and separator assembly 24 falls into a grain container 44 and is transported towards a cleaning system 26. The cleaning system 26 can include an optional pre-cleaning screen 46, a upper sieve 48 (also known as a chopper sieve), a lower sieve 50 (also known as a terminal sieve) and a cleaning fan 52. The grain in sieves 46, 48 and 50 is subjected to a cleaning action by the fan 52 which provides an air flow through the sieves to remove chaff and other impurities such as grain dust by making this aerial material for discharge from the straw cover 54 of the combine 10. The grain container 44 and the pre-cleaning screen 46 oscillate in a retractable way to transport the grain and a finer harvest material other than grain to the upper surface of the upper sieve 48. The upper sieve 48 and the lower sieve 50 are arranged vertically in relation to each other and, similarly, they oscillate in a retractable way to spread the grain through the sieves 48, 50, while allowing the passage of clean grain by gravity through the sieve openings 48, 50.
    [021] The clean grain falls to a clean grain auger 56 positioned in the transverse direction below and in front of a lower sieve 50. The clean grain auger 56 receives a clean grain from each sieve 48, 50 and a bottom container 62 of the cleaning system 26. The clean grain auger 56 transports the clean grain laterally to an elevator generally arranged vertically 60, which can also be referred to as a grain elevator, to transport to the grain tank 28. Waste from cleaning system 26 falls into a waste auger at 62. Waste is transported through a waste auger 64 and a return auger 66 to an upstream end of cleaning system 26 for an action of repeated cleaning. A pair of grain tank augers 68 at the bottom of the grain tank 28 transports the cleaned grain laterally into the grain tank 28 to an unloading auger 30 for unloading the combine 10.
    [022] Harvest material other than grain proceeds through a waste handling system 70. The waste handling system 70 may include a cutter, counter-knives, a windrow door and a waste spreader.
    [023] With reference now to Figure 2, a portion of the agricultural harvester 10 with the cleaning system 26 and an elevator 60 are shown in more detail. As can be seen, a harvest material is supplied to the elevator 60 by the cleaning system 26 which is generally shown as a block to illustrate that any type and portion of a cleaning system can supply a harvest material for the elevator 60 When the cleaning system 26 shown in Figure 1 supplies harvest material for elevator 60, harvest material can be supplied for elevator 60 using clean grain auger 56. It should be understood that elevator 60 can be supplied with harvest material from more than one auger or from a mechanism in addition to an auger, depending on the configuration of the cleaning system.
    [024] Referring now to Figure 3, elevator 60 is shown in greater detail. As can be seen, the elevator 60 includes a housing 74 with a harvest material inlet 76 supplied with clean grain from the cleaning system 26, a tank portion 78 that forms a bottom of the housing 74, an air inlet 80 and an air outlet 82. It should be understood that although the clean grain is described as the harvest material that is transported by elevator 60 when referring to Figures 3 to 9, other harvest material, such as waste, can also be transported by elevator 60 or a grain that is not acceptably cleaned due to high concentrations of MOG. It should also be understood that the elevator 60 can have any position relative to the cleaning system 26 that allows harvest material to be transported from the cleaning system 26 to the elevator 60. A drive circuit 84, shown here as a drive current, is maintained inside the housing 74 and extends from the tank portion 78 of the housing 74 towards a top 86 (shown in Figures 1 to 2) of the housing 74. Although the drive circuit 84 is shown to be a drive chain that can also be referred to as an endless chain, drive circuit 84 can also be a conveyor, cable or other similar construction that forms a circuit through frame 74 and can be oriented to rotate throughout the housing 74. Paddles 88 are connected to drive circuit 84 which can be driven by sprockets 90 to move paddles 88 through housing 74 along drive circuit 84 and transport free grain. time of the harvest material input 76 to the top 86 of the housing 74 where the harvest material can be discharged to the grain tank 28. As shown in Figure 3, the paddles 88 rotate around the lower sprocket 90 in a counterclockwise direction indicated by arrow 92. In this sense, the blades 88 each have a main edge 94 on which the harvest material rests during an upward transport in the elevator 60 and a rear edge 96 which is a bottom of the paddles 88 and will be discussed further below. A blower 98, shown here as a fan, is connected to air inlet 80 and produces a pressurized airflow represented as an arrow 100 which will be discussed further below. Although blower 98 is shown as a fan, blower 98 can be configured as any construction that can produce a presumed airflow that is strong enough to move loose particles. Such a configuration can also be, for example, a nozzle controlled by a solenoid and connected to an air compressor, as described in Patent no. US 8,651,927, which can provide pulses of pressurized air.
    [025] As shown in Figures 3 to 4, housing 74 has a largely rectangular cross section, except for the tank portion 78 that forms the bottom of housing 74 which has a semicircular shape. The tank portion 78 is semicircular in shape to allow the blades 88 to rotate around the sprocket 90 near the bottom of the casing 74 and a transition from a vertical descent by the elevator 60 towards the tank portion 78 to a vertical ascent by lift 60 away from the tank portion 78 and towards the top 86 of the housing 74. The air inlet 80 can be formed on an outer surface 102 of the housing 74 so that an air that is pushed in the elevator 60 by the blower 98 does not contain MOG or other particles that have already been expelled from the combine 10. Although air inlet 80 is shown to be directly connected to blower 98, it is also possible that the air inlet may be formed in other ways to produce a desired pressurized airflow that will be discussed further below. The air outlet 82 is shown to be an inner duct that includes a long wall 104 and a short wall 106 that both extend in a direction parallel to the drive chain 84. As can be seen, the inner duct 82 can include an exhaust port 108 which is directed and extends out of the housing 74 so that any material forced by the exhaust port 108 will be expelled from the agricultural harvester 10. The exhaust port 108 is omitted from being shown in Figure 2 for facilitate the illustration. The long wall 104 and the short wall 106 of the inner duct 82 define a channel 110 between them which leads to an opening 112 of the exhaust port 108. The long wall 104 is longer than the short wall 106 which forms an entrance 114 for the channel 110 at the end of the short wall 106 where a harvest material can be pushed into the inner channel 82 by the pressurized air stream 100 from the blower 98. The channel 110 which is defined by the overlap between the long wall 104 and the wall short 106 can be relatively long in length so that a material grain is inadvertently blown into channel 110 by the pressurized air stream 100 can be prevented from bouncing into the opening 112 of the exhaust port 108 and will instead fall into a deflector 116 on a bottom of the long wall 104 and be returned to a shovel 88 to be transported towards the top 86 of frame 74. As shown in Figure 5, channel 110 can connect to multiple exhaust ports 1 08 which are located on opposite sides of housing 74 which can allow less material to be expelled from the air outlet 82 to be returned to the blades 88. Multiple outlets 108 can be used if the capacity of a single outlet 108 prevents cleaning performance of an elevator blower system. Alternatively, outlet 108 can be placed on either side of elevator 60 based on restrictions on other component positions in relation to elevator 60.
    [026] Carcass 74 may have a throwing section 118 defined in it that is adjacent to tank portion 78 in which a grain that is lifted vertically by paddles 88 is "thrown" as tank portion 78 leaves. The throwing effect that occurs in the throwing section 118 is caused by the displacement of the grain in the paddles 88 by the tank portion 78. As previously described, the tank portion 78 has a semicircular shape to allow the paddles 88 to move from vertically to downward for a vertically upward movement in tank portion 78. A grain is transported to elevator 60 through inlet 76. Due to the acceleration of the blades 88 traveling around sprocket 90, the grain that is transported by the portion of tank 78 is thrown from the main edge 94 of the shovel 88. In some cases, the throwing action is so strong that the grain will impact on the rear edge 96 of the shovel 88. Regardless of the aggressiveness of the throwing action, the grain located in the section pitch 118 has a lower filling density due to the pitch action. While the clean grain is suspended in the air, and in a short period afterwards, it has a reduced filling density compared to other times when the clean grain travels by elevator 60, which allows the pressurized air stream 100 remove light particles like tares. The pressurized air stream 100 can be directed towards the inner duct 82 where this suspension occurs in the section 118. The blower 98 can therefore be configured so that it produces a pressurized air stream 100 that it is strong enough to expel lighter particles, such as chaff or chaff, into the internal conduit 82 while it is air-remitted, but not strong enough to expel heavier particles, such as grain, into the internal conduit 82. The flow current pressurized air 100 can then load the particles expelled through the inner duct 82 to the exhaust port 108 to be removed from the agricultural harvester 10. After the clean grain is thrown, gravity and the upward movement of the blades 88 will do with the clean grain settling on the main edge 94 of a shovel 88, which returns the clean grain to a higher filled density and makes a pressurized air stream that comes into contact with the clean grain less effective effective in removing lighter particles. The length and location of the throwing section 118 can vary based on paddle clearance 88 to paddle 88 in the drive chain 84, the length of the tank portion 78, the linear speed of the paddles 88, the dryness of the clean grain and other factors. Pitch section 118 can be, for example, a section of elevator 60 that begins at an end 120 of tank portion 78 that can be described as the area of housing 74 where housing 74 transitions from an arcuate shape to a shape linear and extends approximately 250 mm above frame 74 towards the top 86 of frame 74. Such a throwing section can be defined for an elevator that has a 160 mm blade-to-blade clearance along drive chain 84 and it is given as an example only and is not intended to limit the scope of the invention.
    [027] Although the pressurized airflow 100 is shown in Figures 3 to 4 as being blown through the blades 88 directly towards the air outlet 82, it is contemplated that other modalities may have the pressurized airflow 100 directed towards the air outlet 82 in different directions. The blower 98 can also be adjusted to supply different pressurized air currents 100 to expel lighter particles at the air outlet 82.
    [028] With reference now to Figures 6 to 7, another embodiment of an elevator 130 according to the present invention is shown. Specifically, the elevator 130 shown in Figures 6 to 7 has a housing 132 with an air inlet 134 that is directed towards a tank portion 136 that forms a bottom of the housing 132 and a blower 138 attached to the air inlet 134 that includes two windmills coupled to provide a pressurized airflow shown as an arrow 140 which is directed at an angle downward towards tank portion 136. As can be seen in Figure 7, airflow 140 is directed in towards an air outlet 142 which is an internal duct that includes a long wall 144 with a deflector 146 and a short wall 148. Deflector 146 is angled so that the pressurized air stream 140 is directed along the surface deflector 146 towards air outlet 142. A channel 150 is defined between the long wall 144 and a short wall 148 which is directed towards exhaust ports 152 which are directed out of the housing 132. The pressurized air flow 140 is dir driven towards deflector 146 so that air flow 140 can be redirected upward to channel 150 and exhaust ports 152. As the clean grain is thrown out of tank portion 136, pressurized air flow 140 it can direct the lighter particles, as described above, against the baffle 146 or the long wall 144 and expel the lighter particles into the channel 150 and the exhaust ports 152 to leave the harvester 10. In this respect, the length channel 150 may allow the grain, which is heavier than the chaff, which is inadvertently expelled towards the exhaust ports 152 to be returned to the blades 88 and to be transported towards the top 86 of the housing 74.
    [029] Referring now to Figures 8 to 9, yet another embodiment of an elevator 160 according to the present invention is shown. Specifically, the elevator 160 shown in Figures 8 to 9 has a housing 162 with an air inlet 164 that is located above an air outlet 166 in relation to a tank portion 168 that forms a bottom of the housing 162. A blower 170 it is attached to the air inlet 164 to direct a pressurized airflow denoted as an arrow 172 towards the air outlet 166 to expel loose particles, such as chaff, towards the air outlet 166 as the loose particles are transported away of the tank portion 168. This modality of elevator 160 is similar to the modality of elevator 130 shown in Figures 6 to 7, with the location of the blower 138 being moved to where the exhaust port 152 was located. In that sense, the air inlet 134 referred to in Figures 6 to 7 is the air outlet 166 shown in Figures 8 to 9 and the air outlet 142 referred to in Figures 6 to 7 is the air inlet 164. As can be observed, the pressurized air stream 172 is directed through the air inlet 164 which is formed as an internal duct which has a long wall 174 with a deflector 176 and a short wall 178 towards the deflector 176 which directs the pressurized air stream 172 towards the air outlet 166. The pressurized air stream 172 is directed so that it can expel loose particles, such as chaff, towards the air outlet 166 and out of the agricultural harvester 10. The air outlet 166 can be formed as a duct that connects to frame 162 and a channel 180 is defined between a pair of duct walls 182 and is directed out of the agricultural harvester 10. The width of channel 180 can be adjusted by changing the distance between the duct walls 182 to form a duct 166 with a channel that doesn’t allow larger, heavier particles like a grain to cross it while allowing smaller, lighter particles like chaff to cross. The length of the channel 180 can also be adjusted to reduce the amount of grain that is inadvertently expelled from the agricultural harvester 10. The channel 180 can lead to an opening 181 which is directed out of the agricultural harvester 10 to expel any material harvest through channel 180 out of agricultural harvester 10.
    [030] Optionally, a grain sensor 184 can be placed in any of the air outlets previously described, such as an air outlet 166 shown in Figures 8 to 9, which can detect an amount of grain that is inadvertently expelled out of the agricultural harvester. The grain sensor 184 can be any type of sensor that can differentiate between grain and tares, such as an optical sensor configured to recognize differences in size between particles that pass through it or a pressure sensor that is configured to recognize particles. cells of different dimensions that hit the sensor. Grain sensor 184 can be placed in an air outlet section 166 where it is almost guaranteed that the grain will be expelled from the combine harvester 10, such as near opening 181, or can be placed near an air outlet entrance 166 for determine how much grain enters the air outlet 166. Grain sensor 184 can be coupled to a controller 186 that can also be coupled to a blower, such as a blower 170. Grain sensor 184 can send signals to controller 186 that are interpreted to determine how much grain is inadvertently expelled into or out of air outlet 166. Controller 186 can be pre-programmed to respond to a predetermined unacceptable level of inadvertent grain expulsion by reducing the power supplied to blower 170, the which reduces the force that the pressurized air stream 172 provides to expel loose crop material into the air outlet 166. The reduction in power for the blower 170 can reduce the amount of and grain that is inadvertently expelled from the agricultural harvester 10. Controller 186 can also be attached to a display (not shown) that can alert a user to the amount of grain that is inadvertently expelled from the agricultural harvester 10, which can prompt the user to manually turn off the blower 170.
    [031] Although this invention has been described in relation to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore designed to cover any variations, uses or adaptations of the invention using the general principles of the same. In addition, this application is designed to cover such derivations of the present disclosure as they arise from common or known practice of the technique to which this invention belongs and which are within the limits of the appended claims.
