Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a bale ejection device. Background Technology

[0002] A baler is a machine used to compress and bundle harvested crops such as hay and straw into bales for easy transport, storage, and use. Balers include stationary balers and towed balers. Towed balers are pulled by tractors in the field for baling operations and offer good baling efficiency.

[0003] The related technology of towed balers includes a baling chamber that can compress and bundle bales. The baling chamber is equipped with a bale ejection device. When multiple compressed bales are bundled in the baling chamber, the bale ejection device can eject all the bales at once, causing them to fall into the pasture. However, there are usually multiple bales in different locations in the pasture, and the number of bales that the bale transport equipment can transport at one time is limited. When the number of bales stacked in the same location by the bale ejection device is greater than the number of bales that the transport equipment can transport at one time, it will lead to the phenomenon that the transport equipment is not fully loaded for the next transport, which reduces the transport efficiency of the equipment. Summary of the Invention

[0004] This application provides a bale ejection device to solve the technical problem that bale ejection devices in related technologies cannot eject a specified number of bales, thereby reducing the transportation efficiency of transportation equipment.

[0005] This application provides a bale ejection device, comprising:

[0006] A grass pusher, which is slidably connected to a guide groove at the bottom of the baling chamber, has a groove along its length and a first opening communicating with the groove.

[0007] A driving component, the driving component being used to drive the grass pusher to advance or reset within the guide groove;

[0008] Multiple grass-pushing teeth are rotatably connected to the groove body. Each grass-pushing tooth is provided with an elastic element between itself and the groove body. The elastic element is used to drive the grass-pushing tooth to extend out of the grass pusher along the first opening. There is a receiving space between adjacent grass-pushing teeth for accommodating grass bales.

[0009] A grass-pushing tooth selection device is configured to, when the grass pusher is reset, sequentially drive at least one of the grass-pushing teeth to rotate along the pushing direction of the grass pusher, so that the grass-pushing tooth rotates into the groove along the first opening.

[0010] In some embodiments, the grass-pushing tooth selection device includes a sliding selector and a drive mechanism. The sliding selector is disposed in the groove and has at least one second opening for the grass-pushing tooth to pass through. The drive mechanism is configured to move the sliding selector relative to the grass pusher when the grass pusher is reset, such that the sliding selector sequentially drives at least one grass-pushing tooth to rotate into the groove along the pushing direction of the grass pusher.

[0011] In some embodiments, the drive mechanism includes a drive stop and a base plate. The drive stop is fixedly mounted on the sliding selector, and the base plate is fixedly mounted on the baling chamber. The drive stop is configured to abut against the base plate when the grass pusher is reset, thereby driving the sliding selector to move relative to the grass pusher.

[0012] In some embodiments, the drive mechanism further includes a selection plate, which is slidably disposed on the base plate along a direction perpendicular to the movement of the grass pusher. The selection plate has a plurality of grooves along the direction of movement of the selection plate, and the depth of the plurality of grooves increases sequentially.

[0013] The drive mechanism further includes a fixing component for fixing the selection plate so that the drive stop is opposite to one of the multiple grooves. When the drive stop abuts against the bottom wall of the multiple grooves from the deepest to the shallowest in sequence, the sliding selector is driven to move gradually so as to drive the multiple grass-pushing teeth in the grass-pushing direction to rotate into the groove in sequence.

[0014] In some embodiments, the drive mechanism further includes a reset component configured to drive the sliding selector to move relative to the grass pusher as the grass pusher moves in the propulsion direction, such that the plurality of grass pushing teeth extend out of the grass pusher along the first opening and the second opening portions.

[0015] In some embodiments, the reset assembly includes a reset slot and a reset member, and the fixing assembly is used to fix the selection plate such that the drive block is opposite to one of the reset slots or one of the plurality of slots;

[0016] The reset slot is formed on the selection plate. The reset member is configured to drive the sliding selector to move relative to the grass pusher when the grass pusher moves in the advancing direction, so that the drive block abuts against the bottom wall of the reset slot, thereby causing each grass pusher to extend out of the grass pusher by means of the elastic member portion.

[0017] In some embodiments, the reset member includes a reset stop fixedly disposed on the sliding selector. The reset stop is configured to abut against the base plate when the grass pusher moves in the advancing direction, thereby driving the sliding selector to move relative to the grass pusher.

[0018] In some embodiments, a strip-shaped hole is provided on the selection plate along the moving direction of the selection plate, and a rod is fixedly provided on the base plate. The rod is slidably connected to the strip-shaped hole along the length direction of the strip-shaped hole. A limiting member is detachably connected to the end of the rod away from the base plate, and a limiting space is formed between the limiting member and the base plate for the selection plate to move into.

[0019] In some embodiments, the fixing assembly includes a fixing plate, a drive rod, and a fixing member. The fixing plate is fixedly disposed on the base plate, and a rotating shaft is rotatably connected to and passes through the fixing plate. One end of the drive rod is fixedly connected to the rotating shaft, and the other end is hinged to the selection plate. The fixing member is used to fix the rotating shaft to rotate.

[0020] In some embodiments, the fixing member includes a plate and a plurality of fixing blocks. The plate is fixedly mounted on the rotating shaft, and the plate has fixing holes for the fixing blocks to be inserted into. When the plurality of fixing blocks are sequentially inserted into the fixing holes, the driving block can sequentially be opposite to the reset groove and the plurality of grooves.

[0021] This application provides a bale ejection device. After compression and baling, bales are located within the baling chamber, and multiple bales are situated in multiple receiving spaces. A pusher tooth selection device allows at least one pusher tooth to rotate sequentially along the pusher's advancing direction when the pusher resets, causing the pusher teeth to rotate into the groove. When the drive unit propels the pusher forward within the guide groove, the pusher teeth extending outside the pusher can push the bales out, while the remaining pusher teeth rotating into the groove cannot push the bales out. The pusher tooth selection device drives a specified number of pusher teeth to rotate into the groove, facilitating the ejection of bales in one operation. The device pushes down a specified number of bales, facilitating the adjustment of the number of bales at the same location on the pasture. This ensures that the transport equipment is fully loaded when transporting multiple bales at the same location multiple times, thereby improving the transport efficiency when transporting multiple bales at different locations on the pasture. Furthermore, lowering a specified number of push teeth facilitates the pushing of bales at a specified location, eliminating the need for the user to push out all bales and then select the bales to be used, further improving the bale pushing effect. The use of elastic elements allows the push teeth, which have rotated into the trough, to return to their original position, so that the push teeth are partially extended outside the pusher.

[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] As described in the background art, the related towing baler includes a baling chamber that can compress and bundle bales. The baling chamber is equipped with a bale ejection device, which includes a push plate and a drive component. The push plate is slidably disposed in the baling chamber, and the drive component is usually a hydraulic cylinder. When multiple compressed bales are bundled in the baling chamber, the hydraulic cylinder drives the push plate to move, so that the push plate can eject all the bales at once, thereby causing the multiple bales to fall into the pasture.

[0043] However, the grasslands are large, and these grasslands are divided into multiple areas. After the grass in the same area is harvested and baled, it is piled up in the same location. Each area has a large number of bales piled up. The number of bales that the transport equipment can carry at one time is limited. When the number of bales piled up in the same location by the bale pusher is greater than the number of bales that the transport equipment can carry at one time, for example, if there are 15 bales piled up in the same location, but the transport equipment can only carry 10 bales at a time, it will result in the transport equipment not being fully loaded for the next transport, or the transport equipment will need to move to the next bale pile to load the truck when it is not fully loaded. When the transport equipment is not fully loaded multiple times, it increases the number of transport times. When the transport equipment moves to load the truck multiple times, it increases the transport distance and reduces the transport efficiency of the transport equipment.

[0044] To address the aforementioned technical problems, this application provides a bale ejection device. When the drive block is opposite to the deepest groove and the bale pusher is reset, the drive block can abut against the bottom wall of the deepest groove, causing the sliding selector to move relative to the bale pusher. At this time, the edge of the first second opening in the bale pusher's advancing direction can abut against the bale pusher tooth, causing the second opening to squeeze the bale pusher tooth to rotate, thereby causing the first bale pusher tooth in the bale pusher's advancing direction to rotate into the groove, while the second second opening and the third second opening in the bale pusher's advancing direction do not abut against the bale pusher tooth. When the drive stop is aligned with the second deepest groove and the grass pusher is reset, the drive stop can abut against the bottom wall of the second deepest groove, causing the sliding selector to move relative to the grass pusher. At this time, the edge of the first second opening in the grass pusher's advancing direction can first abut against the grass pushing teeth. As the sliding selector continues to move, the edge of the second second opening in the grass pusher's advancing direction abuts against the grass pushing teeth, causing the second opening to squeeze the grass pushing teeth to rotate. This causes the first and second grass pushing teeth in the grass pusher's advancing direction to rotate into the groove, while the third second opening in the grass pusher's advancing direction... The opening does not contact the pushing teeth; when the drive stop is opposite the groove with the smallest depth and the pusher is reset, the drive stop can abut against the bottom wall of the groove with the smallest depth, causing the sliding selector to move relative to the pusher. At this time, the edge of the first second opening in the pusher's advancing direction can first abut against the pushing teeth. The sliding selector continues to move, causing the edge of the second second opening in the pusher's advancing direction to abut against the pushing teeth. The sliding selector moves further, causing the edge of the third second opening in the pusher's advancing direction to abut against the pushing teeth, causing the three second openings to squeeze in sequence. The rotation of the three pushing teeth causes the first, second, and third pushing teeth in the direction of the pushing device to rotate into the trough. This ensures that the first three of the five pushing teeth are all in the trough. The pushing tooth selection device drives a specified number of pushing teeth to rotate into the trough, making it easy to push a specified number of bales down at once. This facilitates the adjustment of the number of bales at the same location on the pasture, ensuring that the transport equipment can be fully loaded when transporting multiple bales at the same location multiple times. This improves the transport efficiency when transporting multiple bales at different locations on the pasture.

[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0046] Combination Figures 1 to 3 A bale ejection device, comprising:

[0047] The grass pusher 100 is slidably connected to the guide groove at the bottom of the baling chamber. The grass pusher 100 has a groove 110 along its length and a first opening 120 communicating with the groove 110.

[0048] The driving component 200 is used to drive the grass pusher 100 to advance or reset within the guide groove.

[0049] Multiple grass-pushing teeth 300 are rotatably connected in the trough 110. Each grass-pushing tooth 300 and the trough 110 are provided with an elastic element 310. The elastic element 310 is used to drive the grass-pushing tooth 300 to extend out of the grass pusher 100 along the first opening 120. There is a receiving space 320 between adjacent grass-pushing teeth 300 for accommodating grass bales.

[0050] The grass pusher tooth selection device 400 is configured to, when the grass pusher 100 is reset, sequentially drive at least one of the multiple grass pusher teeth 300 to rotate along the pushing direction of the grass pusher 100, so that the grass pusher tooth 300 rotates into the trough 110 along the first opening 120.

[0051] In this embodiment, the grass pusher 100 is generally elongated, and two such elongated grass pushers 100 are provided. The cross-section of the trough 110 is U-shaped. The baling chamber includes a frame 500, which includes multiple parallel and spaced fixed rods 510. Guide grooves are provided along the length of the fixed rods 510. The grass pushers 100 are slidably connected to the guide grooves of the fixed rods 510. Two of the fixed rods 510 have grass pushing holes 520 along their length, which are used for grass pushing teeth 300 to pass through, allowing the grass pushing teeth 300 to push the bales on the fixed rods 510. A connecting plate 130 is fixedly provided between the two grass pushers 100. The driving component 200 includes a hydraulic cylinder, which is fixedly provided on the frame 500. The connecting plate 130 is fixedly connected to the driving end of the hydraulic cylinder. The hydraulic cylinder drives the connecting plate 130 to move, thereby driving the two grass pushers 100 to move synchronously. Five openings 120 are provided, and five grass-pushing teeth 300 are provided. The five grass-pushing teeth 300 are evenly and spaced on the grass pusher 100, and each of the five grass-pushing teeth 300 corresponds one-to-one with the five first openings 120. Connecting shafts 140 are fixedly provided on both sides of the grass-pushing teeth 300 and are rotatably connected to the opposite surfaces of the trough 110. The elastic element 310 includes a torsion spring, which is sleeved on the connecting shaft 140, and one end of the torsion spring is fixedly connected to the trough 110. On the inner wall of 0, the other end is fixedly connected to the grass-pushing tooth 300; the grass-pushing tooth selection device 400 is configured such that when the grass pusher 100 is reset, the first three grass-pushing teeth 300 of the five grass-pushing teeth 300 are driven to rotate in sequence along the pushing direction of the grass pusher 100, so that the three grass-pushing teeth 300 rotate along the first opening 120 into the groove 110; a bearing 150 is provided on the outer wall of the grass pusher 100, and the bearing 150 is used to slide in the fixed rod 510.

[0052] By adopting the above technical solution, the compressed bales are located in the baling chamber, and multiple bales are located in multiple receiving spaces 320. Through the setting of the pusher tooth selection device 400, when the pusher 100 is reset, three pusher teeth 300 are sequentially driven to rotate along the pushing direction of the pusher 100, thereby causing the pusher teeth 300 to rotate into the groove 110. When the drive unit 200 drives the pusher 100 to advance in the guide groove, the pusher teeth 300 extending outside the pusher 100 can push the bales out, while the remaining pusher teeth 300 that have rotated into the groove 110 cannot push the bales out. The pusher tooth selection device 400 drives a specified number of pusher teeth 300 to rotate into the groove 110. The trough 110 allows for the easy pushing of a specified number of bales at once, facilitating the adjustment of the number of bales at the same location on the pasture. This ensures that the transport equipment can be fully loaded when transporting multiple bales at the same location multiple times, thereby improving the transport efficiency when transporting multiple bales at different locations on the pasture. Furthermore, lowering the specified number of push teeth 300 facilitates the pushing of bales at the specified location, eliminating the need for the user to push out all bales and then select the bales to be used, further improving the pushing effect. The use of elastic element 310 allows the push teeth 300, which have rotated into the trough 110, to return to their original position, so that the push teeth 300 are partially extended outside the pusher 100.

[0053] Combination Figures 2 to 5 The grass-pushing tooth selection device 400 includes a sliding selector 410 and a drive mechanism 420. The sliding selector 410 is disposed in the trough 110 and has at least one second opening 411 for the grass-pushing teeth 300 to pass through. The drive mechanism 420 is configured to move the sliding selector 410 relative to the grass-pushing device 100 when the grass-pushing device 100 is reset, so that the sliding selector 410 sequentially drives at least one grass-pushing tooth 300 to rotate into the trough 110 along the pushing direction of the grass-pushing device 100.

[0054] In this embodiment, two sliding selectors 410 are provided, and the two sliding selectors 410 are respectively disposed in the two grass pushers 100. The sliding selectors 410 are located between the bottom wall of the trough 110 and the connecting shaft 140. Each sliding selector 410 has three second openings 411, and the three second openings 411 correspond one-to-one with the first three grass pushing teeth 300 in the pushing direction of the grass pusher 100. The drive mechanism 420 is configured to drive the sliding selector 410 to move relative to the grass pusher 100 when the grass pusher 100 is reset, so that the sliding selector 410 drives the first three grass pushing teeth 300 in the pushing direction of the grass pusher 100 to rotate into the trough 110.

[0055] By adopting the above technical solution, when the grass pusher 100 is reset, the drive mechanism 420 can drive the sliding selector 410 to move relative to the grass pusher 100, so that the grass pusher 100 moves along the pushing direction of the grass pusher 100, thereby causing the second opening 411 on the sliding selector 410 to intersect with the first opening 120 on the grass pusher 100. At this time, the sliding selector 410 can abut against the grass pushing teeth 300, thereby causing the sliding selector 410 to drive the grass pushing teeth 300 to rotate into the groove 110. The number of second openings 411 determines the number of grass pushing teeth 300 that the sliding selector 410 can drive. By using the setting of the sliding selector 410 and the second opening 411, multiple grass pushing teeth 300 can be driven to rotate while moving, thereby improving the driving effect of multiple grass pushing teeth 300.

[0056] Combination Figures 2 to 6 The drive mechanism 420 includes a drive stop 421 and a base plate 422. The drive stop 421 is fixedly mounted on the sliding selector 410, and the base plate 422 is fixedly mounted on the baling chamber. The drive stop 421 is configured to abut against the base plate 422 when the grass pusher 100 is reset, thereby driving the sliding selector 410 to move relative to the grass pusher 100.

[0057] In this embodiment, there are two drive blocks 421, which are respectively set on the two sliding selectors 410. The cross-section of the drive blocks 421 is rectangular. There is one base plate 422, which spans between the two grass pushers 100. The hydraulic cylinder is fixedly set on the surface of the base plate 422 facing the frame 500.

[0058] By adopting the above technical solution, when the grass pusher 100 is reset, the grass pusher 100 can drive the sliding selector 410 to move synchronously. When the drive block 421 abuts against the base plate 422, the base plate 422 prevents the drive block 421 from moving with the sliding selector 410, causing the sliding selector 410 to pause its movement. At this time, the grass pusher 100 continues to reset, and relative movement occurs between the sliding selector 410 and the grass pusher 100, causing the second opening 411 to intersect with the first opening 120, thereby causing the sliding selector 410 to drive the grass pushing teeth 300 to rotate. The arrangement of the drive block 421 and the base plate 422 has a simple structure and improves the driving effect of driving the relative movement between the grass pusher 100 and the sliding selector 410.

[0059] Combination Figures 5 to 8 The drive mechanism 420 also includes a selection plate 423, which is slidably disposed on the base plate 422 along the moving direction perpendicular to the grass pusher 100. Multiple grooves 424 are formed on the selection plate 423 along the moving direction of the selection plate 423, and the depth of the multiple grooves 424 increases sequentially.

[0060] In this embodiment, there are three grooves 424, and there are two sets of three grooves 424. The two sets of grooves 424 are respectively opposite to the two sides of the grass pusher 100. The grooves 424 are configured to cooperate with the rectangular drive block 421. The side of the groove 424 near the grass pusher 100 in the pushing direction is configured to pass through the selection plate 423. The side of the groove 424 near the grass pusher 100 in the resetting direction is closed.

[0061] Combination Figures 5 to 8 The drive mechanism 420 also includes a fixing component 430 for fixing the selection plate 423 so that the drive stop 421 is opposite to one of the multiple grooves 424. When the drive stop 421 abuts against the bottom wall of the multiple grooves 424 from the deepest to the shallowest in sequence, the drive sliding selector 410 moves gradually to drive the multiple grass pushing teeth 300 in the pushing direction of the grass pusher 100 to rotate into the groove 110 in sequence.

[0062] By adopting the above technical solution, the selection plate 423 can be fixed by the fixing component 430, so that the selection plate 423 drives any one of the grooves 424 to be opposite to the drive stop 421. When the drive stop 421 is opposite to the groove 424 with the deepest depth and the grass pusher 100 is reset, the sliding selector 410 can drive the drive stop 421 to abut against the bottom wall of the groove 424 with the deepest depth. At this time, the sliding selector 410 moves relative to the grass pusher 100, so that the sliding selector 410 drives the first grass pushing tooth 300 to rotate into the groove 110; when the drive stop 421 is opposite to the second groove 424... When the grass pusher 100 is reset, the sliding selector 410 can drive the drive stop 421 to abut against the bottom wall of the second groove 424. At this time, the sliding selector 410 moves again relative to the grass pusher 100, so that the sliding selector 410 drives the first and second grass pusher teeth 300 to rotate into the groove 110. By selecting different grooves 424, the sliding selector 410 can drive different numbers of grass pusher teeth 300 to rotate into the groove 110. Users can select different grass pusher teeth 300 to rotate into the groove 110 as needed, thereby further improving the driving effect of the grass pusher teeth 300.

[0063] In this embodiment, when the drive stop 421 is opposite to the groove 424 with the greatest depth and the grass pusher 100 is reset, the drive stop 421 can abut against the bottom wall of the groove 424 with the greatest depth, causing the sliding selector 410 to move relative to the grass pusher 100. At this time, the edge of the first second opening 411 in the pushing direction of the grass pusher 100 can abut against the grass pushing tooth 300, causing the second opening 411 to squeeze the grass pushing tooth 300 to rotate, thereby causing the first grass pushing tooth 300 in the pushing direction of the grass pusher 100 to rotate into the groove 110, while the second second opening 411 in the pushing direction of the grass pusher 100 and the grass pusher 100... The third second opening 411 does not abut against the grass-pushing tooth 300; when the drive stop 421 is opposite to the second deepest groove 424 and the grass pusher 100 is reset, the drive stop 421 can abut against the bottom wall of the second deepest groove 424, causing the sliding selector 410 to move relative to the grass pusher 100. At this time, the edge of the first second opening 411 in the pushing direction of the grass pusher 100 can first abut against the grass-pushing tooth 300. The sliding selector 410 continues to move, causing the edge of the second second opening 411 in the pushing direction of the grass pusher 100 to abut against the grass-pushing tooth 300, causing the second opening 411 to squeeze the grass-pushing tooth 300. The pusher rotates, causing the first and second pusher teeth 300 in the pushing direction of the pusher 100 to rotate into the groove 110, while the third second opening 411 in the pushing direction of the pusher 100 does not abut against the pusher teeth 300; when the drive stop 421 is opposite to the groove 424 with the smallest depth and the pusher 100 is reset, the drive stop 421 can abut against the bottom wall of the groove 424 with the smallest depth, causing the sliding selector 410 to move relative to the pusher 100. At this time, the edge of the first second opening 411 in the pushing direction of the pusher 100 can first abut against the pusher teeth 300, and the sliding selector... The selector 410 continues to move, causing the edge of the second second opening 411 in the pushing direction of the grass pusher 100 to abut against the grass pushing tooth 300. The sliding selector 410 moves further, causing the edge of the third second opening 411 in the pushing direction of the grass pusher 100 to abut against the grass pushing tooth 300. This causes the three second openings 411 to sequentially squeeze the three grass pushing teeth 300 to rotate, causing the first, second, and third grass pushing teeth 300 in the pushing direction of the grass pusher 100 to rotate into the trough 110. This ensures that the first three grass pushing teeth 300 out of the five grass pushing teeth 300 rotate into the trough 110.

[0064] Combination Figures 5 to 8 The drive mechanism 420 also includes a reset assembly 440, which is configured to drive the sliding selector 410 to move relative to the pusher 100 when the pusher 100 moves in the driving direction, such that a plurality of pusher teeth 300 extend out of the pusher 100 along the first opening 120 and the second opening 411.

[0065] By adopting the above technical solution, when the grass pusher 100 moves along the pushing direction, the reset component 440 can drive the sliding selector 410 to move relative to the grass pusher 100, so that the sliding selector 410 moves along the reset direction. At this time, the sliding selector 410 can drive the second opening 411 to be opposite to the first opening 120 on the grass pusher 100. At this time, due to the setting of the elastic element 310, the grass pushing teeth 300 extend out of the grass pusher 100 along the first opening 120 and the second opening 411, thereby realizing the simultaneous reset of multiple grass pushing teeth 300, improving the reset effect of multiple grass pushing teeth 300, and thus facilitating the next drive of different numbers of grass pushing teeth 300.

[0066] Combination Figures 5 to 8 The reset assembly 440 includes a reset groove 441 and a reset member 442. The fixing assembly 430 is used to fix the selection plate 423 such that the drive stop 421 is opposite to one of the grooves 424 of the reset groove 441 or the plurality of grooves 424.

[0067] The reset groove 441 is provided on the selection plate 423. The reset member 442 is configured such that when the grass pusher 100 moves in the advancing direction, the drive sliding selector 410 moves relative to the grass pusher 100, so that the drive stop 421 abuts against the bottom wall of the reset groove 441, thereby causing each grass pusher 100 to extend out of the grass pusher 100 by means of the elastic member 310.

[0068] In this embodiment, the depth of the reset groove 441 is greater than the depth of the groove 424 with the greatest depth, and the reset groove 441 is located adjacent to the groove 424 with the greatest depth.

[0069] By adopting the above technical solution, the selection plate 423 is fixed by the fixing component 430, so that the drive stop 421 is opposite to the reset groove 441. When the grass pusher 100 moves along the pushing direction, the reset component 442 can drive the sliding selector 410 to move relative to the grass pusher 100, so that the sliding selector 410 moves along the reset direction. At this time, the drive stop 421 just abuts against the bottom wall of the reset groove 441. The sliding selector 410 can drive the second opening 411 to be opposite to the first opening 120 on the grass pusher 100, so that the grass pusher 100 extends out of the grass pusher 100 by the elastic part of the elastic component 310. By setting the reset groove 441 and the reset component 442, the synchronous reset of multiple grass pusher teeth 300 can be realized, and the reset effect of multiple grass pusher teeth 300 is improved.

[0070] Combination Figures 5 to 8The reset member 442 includes a reset stop 443, which is fixedly disposed on the sliding selector 410. The reset stop 443 is configured to abut against the base plate 422 when the grass pusher 100 moves in the pushing direction, so as to drive the sliding selector 410 to move relative to the grass pusher 100.

[0071] In this embodiment, the drive block 421 has a rectangular cross-section, and the reset groove 441 is configured to cooperate with the rectangular drive block 421.

[0072] By adopting the above technical solution, when the grass pusher 100 moves along the pushing direction, the reset stop 443 can abut against the base plate 422. At this time, the sliding selector 410 is stationary, while the driving member 200 always drives the grass pusher 100 to move, so that the sliding selector 410 moves relative to the grass pusher 100, thereby causing the sliding selector 410 to move along the reset direction. When the driving stop 421 just abuts against the bottom wall of the reset groove 441, the sliding selector 410 drives the second opening 411 to face the first opening 120 on the grass pusher 100, thereby causing the grass pushing teeth 300 to extend out of the grass pusher 100 along the second opening 411 and the first opening 120. The setting of the reset stop 443 improves the reset effect of multiple grass pushing teeth 300.

[0073] Combination Figures 5 to 8 A strip-shaped hole 4231 is provided on the selection plate 423 along the moving direction of the selection plate 423. A rod 4221 is fixedly provided on the base plate 422. The rod 4221 is slidably connected in the strip-shaped hole 4231 along the length direction of the strip-shaped hole 4231. The end of the rod 4221 away from the base plate 422 is detachably connected to a limiting member 4222. A limiting space is formed between the limiting member 4222 and the base plate 422 for the selection plate 423 to move into.

[0074] In this embodiment, there are three strip holes 4231, which are located in the middle and on both sides of the selection plate 423, respectively. There are three rods 4221, which correspond one-to-one with the three strip holes 4231. The limiting member 4222 includes a nut that is sleeved and threaded onto the rod 4221. When the drive stop 421 is located in the reset groove 441, the rod 4221 is located at one end of the strip hole 4231. When the drive stop 421 is located in the reset groove 441 with the smallest depth, the rod 4221 is located at the other end of the strip hole 4231.

[0075] By adopting the above technical solution, the strip hole 4231 and the rod 4221 can limit the movement of the selection plate 423 on the base plate 422, thereby preventing the selection plate 423 from separating from the base plate 422. The setting of the limiting member 4222 can detachably connect the selection plate 423 to the base plate 422, thereby facilitating the maintenance and replacement of the selection plate 423.

[0076] Combination Figures 5 to 8 The fixing assembly 430 includes a fixing plate 431, a drive rod 432, and a fixing member 433. The fixing plate 431 is fixedly mounted on the base plate 422. A rotating shaft 434 is passed through and rotatably connected to the fixing plate 431. One end of the drive rod 432 is fixedly connected to the rotating shaft 434, and the other end is hinged to the selection plate 423. The fixing member 433 is used to fix the rotation of the rotating shaft 434.

[0077] In this embodiment, the drive rod 432 includes a first connecting rod 435 and a second connecting rod 436. The length of the first connecting rod 435 is less than the length of the second connecting rod 436. One end of the first connecting rod 435 is fixedly connected to the rotating shaft 434, and the other end is hinged to one end of the second connecting rod 436. The end of the second connecting rod 436 away from the first connecting rod 435 is hinged to the selection plate 423.

[0078] By adopting the above technical solution, the rotating shaft 434 is driven to rotate on the fixed plate 431, which in turn drives the driving rod 432 to rotate. One end of the driving rod 432 can rotate on the rotating shaft 434, and the other end can rotate on the selection plate 423, so that the driving rod 432 drives the selection plate 423 to move. The rotating shaft 434 can be fixed by the fixing member 433, so that the reset groove 441 and any groove 424 on the selection plate 423 are relative to the driving stop 421, thereby improving the effect of driving the reset groove 441 and groove 424 on the selection plate 423 relative to the driving stop 421.

[0079] Combination Figures 5 to 8 The fixing component 433 includes a plate 437 and a plurality of fixing blocks 438. The plate 437 is fixedly mounted on the rotating shaft 434. The plate 437 has fixing holes 439 for the fixing blocks 438 to be inserted into. When the plurality of fixing blocks 438 are inserted into the fixing holes 439 in sequence, the drive stop 421 can be aligned with the reset groove 441 and the plurality of grooves 424 in sequence.

[0080] In this embodiment, the plate 437 is elongated, and four fixing blocks 438 are provided. The four fixing blocks 438 are distributed along the arc direction of the plate 437's rotation. When the fixing holes 439 are sequentially inserted into the four fixing blocks 438, the drive stop 421 can sequentially face the reset groove 441 and the three recesses 424. An installation rod 4371 is provided on the plate 437. Both ends of the installation rod 4371 are fitted with and threaded with limit nuts 4373. A spring 4372 is provided between the limit nut 4373 away from the fixing plate 431 and the plate 437. The spring 4372 is fitted on the installation rod 4371, and one end of the spring 4372 is connected to the limit nut 437. 3. The other end is connected or abutted to the plate 437; when the spring 4372 is in a compressed state, the plate 437 relies on the elastic force of the spring 4372 in the compressed state to drive the fixing hole 439 to be inserted and engaged with the fixing block 438. When it is necessary to separate the fixing block 438 from the fixing hole 439, the plate 437 is moved away from the fixing plate 431, so that the plate 437 further squeezes the spring 4372 to a compressed state, thereby causing the plate 437 to drive the fixing hole 439 to be separated from the fixing block 438. By driving the plate 437 to rotate, the plate 437 can drive the fixing hole 439 to be inserted with the fixing block 438 at different positions.

[0081] By adopting the above technical solution, the setting of the fixing block 438 and the fixing hole 439 improves the accuracy of the relative position of the drive stop 421 with the reset groove 441 and the multiple grooves 424, thereby improving the effect of the grass pusher 100 and the sliding selector 410 driving the drive stop 421 to move into the reset groove 441 and the grooves 424 when they move relative to each other.

[0082] When the drive stop 421 is opposite the deepest groove 424 and the grass pusher 100 is reset, the drive stop 421 can abut against the bottom wall of the deepest groove 424, causing the sliding selector 410 to move relative to the grass pusher 100. At this time, the edge of the first second opening 411 in the pushing direction of the grass pusher 100 can abut against the grass pushing tooth 300, causing the second opening 411 to squeeze the grass pushing tooth 300 to rotate, thereby causing the first grass pushing tooth 300 in the pushing direction of the grass pusher 100 to rotate into the groove 110, while the second second opening 411 and the third second opening 411 in the pushing direction of the grass pusher 100 do not abut against the grass pushing tooth 300; when the drive stop 421 is opposite the second deepest groove 424, the edge of the first second opening 421 in the pushing direction of the grass pusher 100 can abut against the grass pushing tooth 300. 4. When the grass pusher 100 is reset, the drive stop 421 can abut against the bottom wall of the groove 424 with the second deepest depth, causing the sliding selector 410 to move relative to the grass pusher 100. At this time, the edge of the first second opening 411 in the pushing direction of the grass pusher 100 can first abut against the grass pushing tooth 300. The sliding selector 410 continues to move, causing the edge of the second second opening 411 in the pushing direction of the grass pusher 100 to abut against the grass pushing tooth 300, causing the second opening 411 to squeeze the grass pushing tooth 300 to rotate, causing the first and second grass pushing teeth 300 in the pushing direction of the grass pusher 100 to rotate into the groove 110, while the third second opening 41 in the pushing direction of the grass pusher 100... 1. Not in contact with the pusher tooth 300; When the drive stop 421 is opposite to the groove 424 with the smallest depth and the pusher 100 is reset, the drive stop 421 can abut against the bottom wall of the groove 424 with the smallest depth, causing the sliding selector 410 to move relative to the pusher 100. At this time, the edge of the first second opening 411 in the pushing direction of the pusher 100 can first abut against the pusher tooth 300. The sliding selector 410 continues to move, causing the edge of the second second opening 411 in the pushing direction of the pusher 100 to abut against the pusher tooth 300. The sliding selector 410 moves further, causing the edge of the third second opening 411 in the pushing direction of the pusher 100 to abut against the pusher tooth 300, so that the three... The second opening 411 sequentially squeezes the three pushing teeth 300 to rotate, causing the first, second, and third pushing teeth 300 in the pushing direction of the pushing device 100 to rotate into the trough 110. This ensures that the first three pushing teeth 300 out of the five pushing teeth 300 rotate into the trough 110. The pushing tooth selection device 400 drives a specified number of pushing teeth 300 to rotate into the trough 110, thus facilitating the pushing of a specified number of bales at once. This allows for adjustment of the number of bales at the same location on the pasture, ensuring that the transport equipment can be fully loaded when transporting multiple bales at the same location multiple times, thereby improving the transport efficiency when transporting multiple bales at different locations on the pasture.
