    CUTTING PLATFORM WITH PIVOTING CANVAS CARRIERS, AND SIDE CANVAS CARRIER
    Field: [001] The invention refers to canvas spikes. More particularly, it refers to side linings. Even more particularly, it refers to pivoting side tarps.
    Background: [002] Canvas tines employ endless belt conveyors to transport harvest from an alternately moving knife or cutter bar to the combine harvester vehicle that supports the cutting deck and transports the cutting deck through the agricultural field. . Once in the combine harvester vehicle, the harvest is threshed, separated and cleaned.
    [003] Tarpaulins have endless belt conveyors that transport the harvest laterally (the left and right side conveyors) to a central portion of the tarpaulin, and a central conveyor that receives the harvest from these side conveyors and transmits it to back and for the combine harvester.
    [004] The endless belts for the cutting deck periodically wear out. When they wear out, they must be replaced. The typical method of replacing endless belts is to break them longitudinally in a splice and remove them from the machine, around rollers and through narrow spaces. This process takes time. It has therefore been proposed to leave the belt intact in the form of an endless link, to disconnect the front ends of the rollers and slide the endless belts from the left and right side conveyors out of the rollers that support the endless belt.
    [005] Due to the size and weight of the left and right side conveyors, this process can be difficult, if not impossible, for a single person or even a couple of people to do this. It would therefore be beneficial to provide mechanically assisted canvas conveyors capable of lifting and / or holding the rollers to / in an elevated position when the belts are removed. It is an objective of this invention to provide such an arrangement.
    Summary: [006] According to a first aspect of the invention, a cutting platform is provided, comprising: a main canvas frame having left and right sides; a canvas conveyor on the left side, pivotally coupled to the left side of the main canvas frame; a canvas conveyor on the right side, pivotally coupled to the right side of the main canvas frame; wherein the left and right side canvas carriers are made up of a side canvas frame, at least one joint coupling the side canvas frame to the main canvas frame, a first roller supported on an inner end of the side canvas frame , a second roll supported on an outer end of the side canvas frame, an endless belt extending around, and supported on, the first and second rollers, the endless belt having an upper surface arranged to receive separate harvest from from the ground and to transport it laterally towards a central portion of the main canvas frame, the endless belt further defining a front edge arranged to move in a recirculation path adjacent to the knife moving alternately, and further defining a rear edge arranged to move on a recirculation path adjacent to at least one joint, and at least one to height adjuster which has an adjustable working length and is arranged to pivot the side canvas frame upward about an axis of rotation defined by at least one joint when the working length of the at least one height adjuster is changed.
    [007] The height adjuster can be a threaded fastener. The height adjuster can be arranged below at least one hinge. At least one hinge can compel the side canvas frame to pivot with respect to the main canvas frame around a first axis that extends parallel to a lateral extension of the cutting deck. The threaded fastener can rest against the side canvas frame at a point below the first axis. The side canvas frame may further comprise an elongated front element disposed adjacent to a front edge of the endless belt and an elongated rear element which is disposed adjacent to a rear edge of the belt. The elongated front element and elongated rear element are generally parallel. The cutting platform may further comprise at least one holder removably removable to the movable knife alternately, which may further define a rear edge that extends over the front edge of the endless belt. At least one support can be arranged above the left side tarpaulin conveyor and the right side tarpaulin conveyor so that the endless conveyor belts cannot be removed slidably from their respective sliding tarpaulin frames until at least one support is removed. At least one support is a harvesting chute which is arranged to transport harvest from the mobile knife alternately over the front edge of the endless belt.
    [008] According to a second aspect of the invention, the side tarpaulin conveyor for a cutting platform having a left side and a right side, a main frame that extends laterally, and a movable knife alternately fixed to, and extending forward from, a front edge of the main frame, the side tarpaulin carrier comprising: a side tarpaulin frame, at least one hinge configured to couple the side tarpaulin frame to the main tarpaulin frame, a first roll supported on an inner end of the side canvas frame, a second roll supported on an outer end of the side canvas frame, an endless belt extending around, and supported on, the first and second rollers, the belt without end having an upper surface arranged to receive separate harvest from the ground and to transport it laterally towards a central portion of the arm main canvas action, the endless belt further defining a front edge arranged to move on a recirculation path adjacent to the knife moving alternately, and further defining a rear edge arranged to move on a recirculation path adjacent to at least a joint, and at least one height adjuster that has an adjustable working length and is arranged to pivot the side frame upward about an axis of rotation defined by at least one joint when the working length of the at least one adjuster in height is changed.
    [009] The height adjuster can be a threaded fastener. The height adjuster can be arranged below at least one joint. At least one hinge can compel the side canvas frame to pivot with respect to the main canvas frame around a first axis that extends in parallel to a lateral extension of the cutting deck. The threaded fastener can rest against the side canvas frame at a point below the first axis. The side canvas frame may further comprise an elongated front element disposed adjacent to a front edge of the endless belt and an elongated rear element which is disposed adjacent to a rear edge of the belt. The elongated front element and elongated rear element can generally be parallel. The cutting platform may further comprise at least one holder removably removable to the movable knife alternately, which may further define a rear edge that extends over the front edge of the endless belt. The at least one support can be arranged above the left side tarpaulin conveyor and the right side tarpaulin conveyor so that the endless conveyor belts cannot be slidably removed from the left side tarpaulin conveyor and the right side tarpaulin conveyor until the at least one support is removed. The at least one support may be a harvesting chute which is arranged to transport harvesting from the movable knife alternately over the front edge of the endless belts.

    Detailed Description: [0017] In the description below, the terms "forward", "ahead of" and the like refer to the direction of travel of the head when it is traveling across the field in a straight line harvesting the crop. The direction is identified in the Figures by the arrow “V”. The terms "backward", "rear", "to the rear", "back" and similar terms refer to a direction opposite to the direction ahead.
    [0018] In Figure 1, the cutting platform 100 comprises a main canvas frame 102, a left side canvas conveyor 104, a right side canvas conveyor106, a central conveyor 108, and an alternately movable knife 110.
    [0019] The main canvas frame 102 supports the left side canvas conveyor 104, the right side canvas conveyor106, the central conveyor 108 and the movable knife 110 alternately. A main frame portion 112 of the main canvas frame 102 is configured to be supported on a combined harvester feeder (not shown) in a conventional manner. In this way, the cutting platform 100 is transported through an agricultural field in a "V" direction that is perpendicular to the longitudinal extension of the cutting platform 100 and parallel to the ground.
    [0020] The left side tarpaulin conveyor 104 is the right side tarpaulin conveyor106 extend perpendicular to the direction of travel, and transport harvest in a direction perpendicular to the direction of travel of the cutting deck 100, as indicated by the overlapping arrows on the conveyors .
    [0021] The central conveyor 108 extends generally parallel to the direction of travel. The endless belt comprising the central conveyor 108 moves backwards in a direction indicated by the arrow superimposed on the conveyor. The central conveyor 108 receives harvest material which falls out of the inner ends of the left side tarpaulin carrier 104 and the right side tarpaulin conveyor106. Material falling on the central conveyor 108 carried backwards through an opening in the main canvas frame 102. This material is carried backwards into the feeder (not shown) and into the combined harvester (not shown) for further processing .
    [0022] The mobile knife 110 alternately is supported on the main canvas frame and extends laterally across substantially the entire width of the main canvas frame 102. The mobile knife 110 is alternately arranged close to the ground in order to separate crop plants at its roots, and allows the upper portion of the separate plants to fall on the left side tarpaulin carrier 104, the right side tarpaulin carrier 106, and the central conveyor 108.
    [0023] Figure 2 illustrates the cutting platform 100 of Figure 1, where the harvest divider at the right end of the cutting platform 100 is removed and the endless belt that forms the movable surface of the right side tarpaulin conveyor106 is also removed.
    [0024] The left side canvas conveyor 104 and the right side canvas conveyor106 are identically constructed, but in mirror image relation around a plane that extends vertically and back and forth through the lateral central point of the platform cutting 100.
    [0025] The main canvas frame 102 comprises a main frame element 112, cutter bar supports 114, and rear sheets 116.
    [0026] The main frame element 112 is generally tubular and extends laterally through the lower rear part of the cutting platform 100. A plurality of knife holders 114 are attached to the main frame element 112 and extend forward from the same. They are spaced across the width of the cutting platform 100. At their front ends, they are alternately attached to the movable knife 110. The knife holders 114 alternately support the movable knife 110 in a fixed position in front of the main frame element 112. The knife holders 114 alternately support the movable knife 110 in parallel with, and generally in front of, the main frame element 112.
    [0027] The right side canvas conveyor106 comprises an endless belt 118 (Figure 1) and a side canvas frame 120. The endless belt 118 is removed in Figure 2 for easier observation of the side canvas frame 120.
    [0028] The endless belt 118 is typically composed of a fabric belt embedded in an elastomeric compound.
    [0029] Referring to Figures 2 and 3, the side canvas frame 120 comprises a generally flat frame 122, a first roll 124 and a second roll 126. The generally flat frame 122, first roll 124, and second roll 126, are coupled together to form a generally flat structure, around which the endless belt 118 is wound. The first roller 124 is driven in rotation by a motor (not shown). The second roll 126 is a crazy roll. The motor (not shown) that drives the first roll and the second roll causes the flat top surface of the endless belt 118 to move in a direction indicated by the arrow superimposed on the endless belt 118 in Figure 1.
    [0030] The first roller 124 and the second roller 126 are supported on the generally flat frame 122 so that their longitudinal and rotational axes are parallel, with the first roller 124 positioned at the innermost end of the generally flat frame 122, and the second roller 126 positioned at the outermost end of the generally flat frame 122. [0031] Referring now to Figure 3, the generally flat frame 122 includes a rear frame element 128, front frame element 130, connecting elements 132, 134 , 136, 138, 140, 142, and tensioning mechanism 144.
    [0032] The rear frame element 128 extends parallel to the main frame element 112 and is pivotally coupled to the main frame element 112. The rear frame element 128 is an elongated element that is supported on joints to pivot with respect to main frame element 112 about an axis which generally extends parallel to the longitudinal extension of the main frame element 112 and the longitudinal extension of the rear frame element 128.
    [0033] The first roller 124 is supported on the inner ends of the rear frame element 128 and the front frame element 130 for rotation about a central longitudinal axis of the first roller 124. The second roller 126 is supported on the ends outer frame element 128 and front frame element 130 to slide laterally in and out with respect to the outer ends of frame elements 128, 130, and to pivot with respect to the outer ends of rear frame element 128 in the element front frame 130 about a central longitudinal axis of the second roll 126.
    [0034] The tensioning mechanism 144 comprises an adjustment element 146, a belt crank 148, a connection connection 149, and a tensioning arm 150. The adjustment element 146 extends through a hole in the rear wall of the platform cutting edge 100 so that it can be rotated by the operator to increase or decrease the tension on the endless belt 118. When the adjusting element 146 is rotated, it moves in the direction indicated by arrow 152. This movement causes the crank pivot belt 148 around the belt crank support 153. These pivoting movements of the belt crank 148, in turn, cause the tensioning arm 150 to move laterally with respect to the other components of the generally flat frame 122. This lateral movement of the tensioning arm 150 causes the second roller 126, which is supported for rotation on the tensioning arm 150, to move laterally inward and outward (depending on direction of movement of the tension arm 150 and indicated by arrow 154). This lateral movement inward and screw out, in turn, increases and decreases, respectively, the distance between the first roller 124 and the second roller 126. Thus, when the operator manipulates the adjusting element 146, he can selectively increase or decrease the tension on the endless belt 118, including decreasing the tension sufficiently to allow the endless belt 118 to be completely loose, and therefore to be slidably removed from the side canvas frame 120.
    [0035] Two elongated belt supports 155, 156 are supported on and above the upper surfaces of the connecting elements 132, 134, 136, 138, 140, 142, to provide a smooth, relatively low friction surface, which is capable of to support the lower surface of the upper branch of the endless belt 118 to slide in relation to the movement when the endless belt 118 is driven in a recirculating movement around the first and second rollers 124, 126.
    [0036] The side canvas frame 120 is supported on joints to pivot up and down with respect to the main frame element 112. This pivoting movement is prevented during normal operation by attaching the front frame element 130 to the alternately movable knife 110. Supports 137 are attached to the movable knife 110 alternately and extend backwards thereto, partially overlapping the endless belt 118. Supports 157 are attached to stationary portions of the movable knife 110 alternately by threaded fasteners 158. In Figure 3, two of these supports 157 are shown, each being alternately attached to the movable knife 110 by three threaded fasteners 158. Four more of these supports are provided to substantially secure the entire length of the front frame member 132 of the movable knife alternately 110. These four additional supports have been removed for convenience of illustrating dog. The supports 157 cover an interstice 160 which is provided between the front frame element 130 and the movable knife alternately 110. The supports 157 function as a harvesting ramp to transport harvest from the movable face alternately over the interstice 160, and on the surface endless belt. If all six of the supports 157 were illustrated in Figure 3, the supports 157 would extend through the front edge of the front frame element 130, substantially cover the entire front edge of the endless belt, and substantially prevent the crop from falling into the interstice 160 or to be inserted in the space between the front edge of the endless belt and the front frame element 130.
    [0037] With reference to Figure 4, four joints 162, 164, 166, 168 are attached to the supports 170, which form a portion of the main frame element 112. The joints 162, 164, 166, 168 are provided for pivotally coupling the rear frame element 128 (and thus the side canvas frame 120 and the right side canvas conveyor106) to the supports 170 and thus to the main frame element 112 of the main canvas frame 102. The joints 162, 164, 166, 168 compel the side canvas frame 120 to pivot with respect to the main frame element 112 about an axis which generally extends horizontally and longitudinally passing through, and defined by, all four hinges, which is parallel to the main frame element 112 and the rear frame member 128.
    [0038] In Figures 5 and 6, the joint 166 can be seen in greater detail. Hinge 164 is identically constructed, but spaced from hinge 166, close to the opposite (inner) end of rear frame element 128. The description below its four applies to both hinge 164 and hinge 166, although only the hinge 166 is illustrated. The hinge 166 includes a hinge pin 172, around which the side canvas frame 120 pivots with respect to the main frame element 112. Alternatively, three (or less) of the hinges can be removed, thereby supporting the side canvas frame over at least one joint (or more).
    [0039] The height adjuster 174 has an adjustable working length and is engaged with both the support 170 and the rear frame element 128. The working length of the height adjuster 174 refers to the distance between the height adjuster connection up to the main frame (in this case a threaded through hole) and the connection of the height adjuster (in this case its backrest) to the side canvas frame 120.
    [0040] The height adjuster 174 is shown here as a threaded element, for example, a jack screw, and changes its working length when it is rotated. When it is rotated, it therefore changes the distance between the side canvas frame 120 and the support 170 of the main frame element 112 and therefore changes the angle between them.
    [0041] In the mode shown here, when the height adjuster 174 is screwed into the support 170, its other end (the working end of the height adjuster 174) is moved further away from the support 170. The working end the height adjuster 174 leans against the rear frame element 128 below pin 172. When the height adjuster 174 increases its working length, it causes the rear frame element 128 to pivot upwards with respect to the canvas frame lateral 120, pivoting around the longitudinal axis defined by the joints 162, 164, 166, 168, and thus changing their relative angular positions.
    [0042] In an alternative arrangement, the height adjuster 174 and the hinge pin 172 could have exchanged their positions, so that the height adjuster 174 is arranged above the hinge pin 172. In these relative positions, the decrease in length The height adjuster 174 would serve to raise the front edge of the side canvas frame 120 by decreasing the distance between the upper portion of the rear frame element 128 and the support 170.
    [0043] Two joints, the joint 164 and the joint 166, are identically constructed, each having an associated height adjuster 174. To maintain the side canvas frame 120 with light hair, it is beneficial to provide more than one height adjuster 174, although any of the height adjusters 174 would work on their own. Returning to Figure 4, the two height adjusters 174 are spaced approximately 20% from the opposite ends of the side canvas frame 120. If a single height adjuster was desired, this height adjuster can also be arranged at the center point side canvas frame 120.
    [0044] The joints 162 and 168 are similarly constructed as the joints 164 and 166, but with a narrower support 170 and no height adjuster 174. In an alternative embodiment, each of the joints 162 and 168 could be built identical to the joints 164 and 166 and either or both be built with height adjusters 174. In these arrangements, there were three or four height adjusters 174 in total. The only practical limit on the number of height adjusters 174 provided for each side conveyor is the amount of time it would take to adjust them during the lifting process. The more height adjusters 174 provided, the less the load on each height adjuster 174 and therefore the easier to adjust any individual height adjuster 174, which is a benefit. However, the more height adjusters 174 provided, the longer it takes to adjust each one, therefore, increasing the amount of time it takes to raise the side canvas frame 120, which is a disadvantage.
    [0045] In Figure 7, the relative positions of the side canvas frame 120 can be seen when the height adjuster 174 is in two different positions. In the first position, position 176, height adjuster 174 has been retracted, its working length reduced, and the front edge of side canvas frame 120 lowered to its operating position. In the second position, position 178, height adjuster 174 has been extended, its working length increased, and the front edge of side canvas frame 120 is raised to its belt changing position.
    [0046] In typical practice, the operator first removes all of the threaded fasteners 158 that hold the front edge of the supports 157 to the movable knife alternately 110. The operator then moves to the rear of the cutting deck 100 and manipulates the adjustment element 146 at the rear of the cutting deck 100 to loosen the endless belt 118 over the first and second rollers 124, 126. Once loosened, the operator then manipulates the height adjusters 174 by increasing their working length and pivot thus the side canvas frame 120 and the first and second rollers 124, 126 upwards into the air, as shown in Figure 7 in dashed lines.
    [0047] Alternatively, the operator can raise the front edge of the side conveyors manually, and someone else can change (in this mode, increase) the working length of the height adjusters 174 to keep the side conveyor in the selected position. By lifting the front edge of the side conveyors and pivoting them upwards, the load on the height adjusters 174 is eliminated. This adds an additional step to the process, but is faster, as it removes the load from the 174 height adjuster, which makes it easier and faster to increase the length of each 174 height adjuster.
    [0048] Once lifted, the operator slides the endless belt 118 forward and out of the side canvas frame 120 without having to cut or otherwise separate the belt to form one or more elongated sheets. The operator can then slide a replacement belt over the side canvas frame 120 and follow the steps in reverse order to secure the side canvas frame and the new endless belt in their operating positions.
    [0049] This process provides a quick and easy way to replace an endless side canvas belt on a cutting platform. Through the provision of height adjusters 174, the operator is free to move around the canvas platform, once when the side canvas frame is lifted into the air and to remove and replace the belt in a single manual step.
    [0050] The various devices described in this description suggest several types for practicing the invention. Other ways of putting the invention into practice are also possible, as long as they fall within the scope of the claims.
