Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly relates to a horizontal baler mounted at the rear of a semi-feed combine harvester. Background Art

[0002] For the treatment of straw by existing semi-feed combine harvesters, generally there are two methods: (1) using the built-in straw cutter of the harvester and returning the chopped straw to the field; (2) not using the straw cutter, laying the straw in strips in the field, in which case farmers can only manually recycle the straw, or use a self-powered baling machine and a baling machine mounted on a tractor to bale and recycle it. Manually recycling straw is time-consuming, laborious, costly, and has very low efficiency, directly affecting the benefits of straw recycling and comprehensive utilization. Therefore, there is an urgent need to add a baling device to the semi-feed combine harvester to meet the requirements of straw recycling technology. Summary of the Invention

[0003] The purpose of the present invention is to provide a horizontal baler mounted at the rear of a semi-feed combine harvester. By mounting the baler behind the straw cutter of the semi-feed combine harvester and transmitting the power of the straw cutter to the baler through a belt, the harvester can directly complete the work of harvesting → threshing → straw baling, serving multiple purposes with one machine.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions:

[0005] A horizontal baler mounted at the rear of a semi-feed combine harvester includes a rear-mounted baler. The baler includes a straw feeding mechanism, a straw arranging mechanism, a baling mechanism, and a tying mechanism. The straw arranging mechanism is arranged on one side opposite to the straw discharge port of the threshing part. The straw feeding mechanism is located above the straw arranging mechanism. The baling mechanism is located on one side of the straw arranging mechanism. The tying mechanism is located above the baling mechanism. The straw feeding mechanism and the straw arranging mechanism are connected by Chain A. The straw arranging mechanism and the baling mechanism are connected by Chain C. The baling mechanism and the tying mechanism are connected by Chain B.

[0006] By adopting the above technical solutions, the straw feeding mechanism feeds the threshed straw into the area of the straw arranging mechanism. The straw arranging mechanism further arranges the stubble part of the straw. The straw arranging mechanism is arranged on one side opposite to the straw discharge port of the threshing part, which can make the stubble of the straw opposite to the position of the straw arranging mechanism, so that the stubble is easier to be leveled, facilitating baling. The arranged straw gradually gathers and is squeezed by the baling mechanism, and finally is baled by the baling mechanism and the tying mechanism. The whole process is automatically continuous, greatly reducing the labor intensity of manually recycling straw, with high recycling efficiency. The recycled straw forms bundles, which are convenient for storage and handling.

[0007] A further setting of the present invention is that the baler further includes a power mechanism, the power mechanism is coaxially connected to the cutter pulley, and the cutter pulley is connected to the threshing part pulley through Belt A.

[0008] By adopting the above technical solution, when the baler works, the power of the threshing part pulley is transmitted to the cutter pulley through Belt A. When the cutter pulley rotates, it drives the power mechanism coaxially connected to the cutter pulley, and then the power is transmitted to each mechanism of the baler through the power mechanism. The entire baler can directly complete the work of harvesting → threshing → straw baling without additional power, which can be used for multiple purposes, has a simple structure, and low energy consumption.

[0009] A further setting of the present invention is that the power mechanism includes: a baler driving wheel, Belt B, Sprocket A, Link A, Chain A, Sprocket B, and a baler pulley. The baler driving wheel is coaxially connected to the cutter pulley. The baler driving wheel is connected to the baler pulley through Belt B. The baler pulley is coaxially connected to Sprocket B. Sprocket B is connected to Sprocket A through Chain A. Sprocket A is connected to the grass-pulling mechanism through a first transmission mechanism. Sprocket B is connected to the baling mechanism through a second transmission mechanism. Sprocket A is connected to the straw arranging mechanism through Link A.

[0010] By adopting the above technical solution, when the cutter pulley rotates with the threshing part pulley, it drives the baler driving wheel to rotate synchronously. When the baler driving wheel rotates, it drives the baler pulley to rotate synchronously. When the baler pulley rotates, it drives Sprocket B to rotate synchronously. When Sprocket B rotates, it transmits the power to Sprocket A through Chain A. At the same time, when Sprocket B rotates, it transmits the power to the baling mechanism through the second transmission mechanism. During the operation of the baling mechanism, the power is transmitted to the knotting mechanism through Chain B. Sprocket A transmits the power to the straw arranging mechanism through Link A, so as to realize the sequential transmission of the kinetic energy of the threshing part to each mechanism of the baler through the power mechanism, thus realizing the continuous operation of harvesting → threshing → baling. Each mechanism is relatively independent and coordinated with each other, without a complex control system, and can realize continuous automatic operation only through simple mechanical connections, with low equipment cost and good reliability.

[0011] A further setting of the present invention is that the first transmission mechanism includes: a hexagonal shaft tube A and a hexagonal shaft A. One end of the hexagonal shaft tube A is connected to Sprocket A. The other end of the hexagonal shaft tube A inserts the hexagonal shaft A. The hexagonal shaft A can move back and forth along its axis for adjustment. The other end of the hexagonal shaft A is connected to the claw mechanism A in the grass-pulling mechanism through a universal joint A.

[0012] By adopting the above technical scheme, the hexagonal shaft A can be adjusted by moving back and forth along its axis, so that the claw mechanism A connected to the other end of the hexagonal shaft A can push the straw discharged by the harvester to the straw sorting mechanism for sorting, and then collect and squeeze it through the baling mechanism, and finally bale it through the baling mechanism and the knotting mechanism. By adjusting the position where the hexagonal shaft A is inserted into the hexagonal shaft tube A, the moving range of the claw mechanism A can be effectively adjusted to adapt to straws of different lengths, with better adaptability.

[0013] The present invention is further configured as follows: the second transmission mechanism includes: a hexagonal shaft tube B and a hexagonal shaft B, one end of the hexagonal shaft tube B is connected to the sprocket B, the other end of the hexagonal shaft tube B is inserted into the hexagonal shaft B, the hexagonal shaft B can move back and forth along its axis for adjustment, and the other end of the hexagonal shaft B is connected to the sprocket F through a universal joint B.

[0014] By adopting the above technical solution, the second transmission mechanism can adjust the position of the hexagonal shaft B inserted into the hexagonal shaft tube B as needed, and the position of the baling mechanism connected thereto can be adjusted by changing the position of the hexagonal shaft B inserted into the hexagonal shaft tube B, so that the baling mechanism can be adjusted according to different straw lengths and different baling rope positions, and has better adaptability.

[0015] The present invention is further configured as follows: the straw sorting mechanism includes: a connecting rod B, a connecting rod C, a swing arm A, a swing arm B, a swing arm bearing seat and a sorting plate, the swing arm A and the swing arm B are respectively installed on the swing arm bearing seats through a rotating shaft, the swing arm bearing seats are fixedly connected to the baler frame, the sorting plate is respectively connected to the same end of the swing arm A and the swing arm B, the swing arm A and the swing arm B are respectively hinged to the two ends of the connecting rod C, the swing arm A is hinged to one end of the connecting rod B, the other end of the connecting rod B is hinged to the swing arm, the swing arm is connected to the hexagonal shaft C, and the hexagonal shaft C is connected to the sprocket A through the connecting rod A.

[0016] By adopting the above technical solution, when the hexagonal shaft C rotates, it drives the swing arm to rotate. Through the swing of the swing arm, the swing rod mechanism formed by the connecting rod B and the connecting rod C forces the swing arms A and B to reciprocate, thereby enabling the finishing plate connected to the swing arms A and B to reciprocate. The surface of the finishing plate faces the straw stubble part, and the upper surface of the swing arm bearing seat serves as the supporting surface for the straw. While the finishing plate reciprocally pats the straw stubble part, the straw is shaped by combining with the swing arm bearing seat. The swing rod mechanism formed by the swing arm, the connecting rod B, and the connecting rod C converts the rotational motion of the hexagonal shaft C into the reciprocating motion of the swing arms A and B. The structural design is ingenious. At the same time, since the hexagonal shaft C used to drive the swing rod mechanism formed by the swing arm, the connecting rod B, and the connecting rod C is connected to the sprocket A through the connecting rod A, and the power at the sprocket A is respectively transmitted to the straw sweeping mechanism and the baling mechanism through the first transmission mechanism and the second transmission mechanism. Therefore, the straw finishing mechanism cooperates with the straw sweeping mechanism and the baling mechanism, and they work together to further improve the baling effect of the straw.

[0017] The further setting of the present invention is that: arc-shaped holes for the movement trajectories of the swing arms A and B are formed on the surface of the swing arm bearing seat.

[0018] By adopting the above technical solution, arc-shaped holes for the movement trajectories of the swing arms A and B are formed on the surface of the swing arm bearing seat to ensure that the swing arms A and B operate along the set trajectories. Then, the reciprocating movement path and amplitude of the finishing plate are controlled by the running paths of the swing arms A and B, making the stubble more leveled and facilitating baling. At the same time, the swing arms A and B move along the arc-shaped holes, which can effectively avoid the phenomenon that the movement trajectories of the swing arms A and B deviate due to the impact when the finishing plate reciprocally pats the straw stubble part, and the overall structure has better stability.

[0019] The further setting of the present invention is that: the sprocket F in the second transmission mechanism is connected to the sprocket E through the chain C, the sprocket E is connected to the input shaft of the gearbox, the output shaft of the gearbox is connected to the baling mechanism, the gearbox is connected to the chain box A through the transmission shaft B. The chain box A includes the sprocket C, the sprocket D, and the chain B. The transmission shaft B is connected to the sprocket D, the sprocket D is connected to the sprocket C through the chain B, and the sprocket C is connected to the knotting mechanism and the claw mechanism B through the transmission shaft A.

[0020] By adopting the above technical solution, the second transmission mechanism transmits the power to the sprocket E through the sprocket F, then transmits it to the gearbox through the sprocket E, and finally transmits it to the baling mechanism through the gearbox. At the same time, the gearbox also transmits the power to the chain box A through the transmission shaft B, and then transmits it to the knotting mechanism and the claw mechanism B through the chain box A. The knotting mechanism ties the straw into bales, and then the claw mechanism B discharges the baled straw from the baler.

[0021] A further setting of the present invention is that the pawl mechanism B is connected to the transmission shaft A through a connecting rod. One end of the connecting rod is fixedly connected to the pawl mechanism B, and the other end of the connecting rod is connected to the transmission shaft A.

[0022] By adopting the above technical solution, when the transmission shaft A rotates, it drives the connecting rod to rotate. When the connecting rod rotates, it drives the pawl mechanism B to reciprocate, so as to remove the bundled straw from the baler. The transmission shaft A serves as the power shaft of the knotting mechanism on the one hand and the power shaft of the pawl mechanism B on the other hand, coordinating the knotting mechanism and the pawl mechanism B to jointly achieve continuous operation.

[0023] A further setting of the present invention is that the baling mechanism includes a hay pressing mechanism and a baling device. The hay pressing mechanism includes a hay pressing arm and a connecting rod mechanism for driving the hay pressing arm to reciprocate. The connecting rod mechanism includes a driving connecting rod, an intermediate connecting rod and a driven connecting rod. One end of the driving connecting rod is connected to the output shaft of the gearbox, the other end of the driving connecting rod is connected to one end of the intermediate connecting rod, the other end of the intermediate connecting rod is connected to one end of the driven connecting rod, the other end of the driven connecting rod is hinged to the outer shell of the gearbox, and the hay pressing arm is fixed to the end of the intermediate connecting rod. The baling device includes a baffle rod, a baler and a binding rope threading part. One end of the baffle rod is connected to the transmission mechanism in the gearbox through an adjusting plate. A plurality of adjusting holes are provided on the adjusting plate, and the baffle rod is fixedly connected to the adjusting plate through the adjusting holes. The transmission mechanism is connected to the baler and the binding rope threading part.

[0024] By adopting the above technical solution, when the baling mechanism performs the baling operation, the hay pressing arm in the hay pressing mechanism gradually gathers and presses the straw during the reciprocating motion. As the diameter of the hay bale increases, the hay bale continuously presses the baffle rod. Therefore, the pressing force transmitted to the baffle rod gradually increases. When it increases to the set value, the baffle rod starts to rotate. When the baffle rod rotates, it triggers the transmission mechanism in the gearbox to start moving. When the transmission mechanism moves, it drives the baler and the binding rope threading part to work for baling. By connecting the baffle rod to different adjusting holes on the adjusting plate, it is possible to increase or decrease the space of the hay bale, that is, to increase the diameter of the hay bale, so as to realize baling straw with different bale diameters according to the different needs of users.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention feeds the straw after threshing into the area of the straw arranging mechanism through a straw removing mechanism. The straw arranging mechanism arranges on one side opposite to the straw discharge port of the threshing part, and arranges the straw cutting stubble part. By doing so, the cutting stubble of the straw can be made opposite to the position of the straw arranging mechanism, making it easier to level the cutting stubble, facilitating baling. The arranged straw gradually converges and is compressed through the baling mechanism, and finally is baled through the baling mechanism and the knotting mechanism. The whole process is automatically continuous, greatly reducing the labor intensity of manual straw recycling, with high recycling efficiency. The recycled straw forms bundles, which are convenient for storage and handling.

[0027] 2. When the baler of the present invention works, the power of the threshing part pulley is transmitted to the cutter pulley through Belt A. When the cutter pulley rotates, it drives the power mechanism coaxially connected to the cutter pulley, and then transmits the power to each mechanism of the baler through the power mechanism. Without additional power, the whole baler can directly complete the work of harvesting → threshing → straw baling by the harvester. It has multiple functions in one machine, with simple structure and low energy consumption. Each mechanism is relatively independent and coordinated with each other, without a complex control system, and can achieve continuous automatic operation only through simple mechanical connections, with low equipment cost and good reliability.

[0028] 3. In the present invention, both the hexagonal shaft A and the hexagonal shaft B can move back and forth along their axes for adjustment, so that the claw mechanism A and the baling mechanism connected to the other end can adapt to the baling work of straws with different lengths and straws at different bale rope positions, making the application range of the whole device wider and the adaptability better.

[0029] 4. The straw arranging mechanism of the present invention drives the swing arm to rotate through the rotation of the hexagonal shaft C. By the rotation of the swing arm, the swing rod mechanism formed by the connecting rod B and the connecting rod C forces the swing arm A and the swing arm B to reciprocate. As a result, the arranging plate connected to the swing arm A and the swing arm B reciprocates. The surface of the arranging plate faces the straw cutting stubble part, and the upper surface of the swing arm bearing seat serves as the supporting surface of the straw. While the arranging plate reciprocally pats the straw cutting stubble part, combined with the swing arm bearing seat, the straw is arranged into a shape. The swing rod mechanism formed by the swing arm, the connecting rod B, and the connecting rod C converts the rotational motion of the hexagonal shaft C into the reciprocating motion of the swing arm A and the swing arm B. The structural design is ingenious. At the same time, since the hexagonal shaft C used to drive the swing rod mechanism formed by the swing arm, the connecting rod B, and the connecting rod C is connected to the sprocket A through the connecting rod A, and the power at the sprocket A is respectively transmitted to the straw removing mechanism and the baling mechanism through the first transmission mechanism and the second transmission mechanism. Therefore, the straw arranging mechanism cooperates with the straw removing mechanism and the baling mechanism, and further improves the baling effect of the straw.

[0030] 5. In the present invention, arc-shaped holes for the movement trajectories of swing arm A and swing arm B are provided on the surface of the swing arm bearing seat, ensuring that swing arm A and swing arm B operate along the set trajectories. Then, the reciprocating movement path and amplitude of the leveling plate are controlled by the movement paths of swing arm A and swing arm B, making the stubble more leveled and facilitating baling. At the same time, swing arm A and swing arm B move along the arc-shaped holes, which can effectively avoid the phenomenon that the movement trajectories of swing arm A and swing arm B deviate due to the impact when the leveling plate reciprocally pats the stubble part of the straw, and the overall structure has better stability.

[0031] 6. In the present invention, when the baling mechanism performs baling operations, the pressing arm in the straw pressing mechanism gradually gathers and presses the straw during the reciprocating movement. As the diameter of the bale increases, the bale continuously presses against the stop rod, so the pressing force transmitted to the stop rod gradually increases. When it increases to the set value, the stop rod starts to rotate. When the stop rod rotates, it triggers the transmission mechanism in the gearbox to start moving. When the transmission mechanism moves, it drives the baler and the binding string threading part to work for baling. By connecting the stop rod to different adjustment holes on the adjustment plate, it is possible to increase or decrease the bale space, thereby increasing the bale diameter, and thus realizing baling straw with different bale diameters according to different user requirements, with good adaptability.

Specific embodiments

[0040] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Refer to Figures 1 to 6, a horizontal baler mounted at the rear of a semi-feed combine harvester, including a baler 100 mounted at the rear. The baler 100 includes a straw guiding mechanism, a straw arranging mechanism, a baling mechanism 38 and a tying mechanism 24. The straw arranging mechanism is arranged on one side opposite to the straw discharge port of the threshing part. The straw guiding mechanism is located above the straw arranging mechanism. The baling mechanism 38 is located on one side of the straw arranging mechanism. The tying mechanism 24 is located above the baling mechanism 38. The straw guiding mechanism and the straw arranging mechanism are connected by chain A8. The straw arranging mechanism and the baling mechanism 38 are connected by chain C33. The baling mechanism 38 and the tying mechanism 24 are connected by chain B28. The straw guiding mechanism feeds the threshed straw into the area of the straw arranging mechanism. The straw arranging mechanism arranges the cut stubble part of the straw. The straw arranging mechanism is arranged on one side opposite to the straw discharge port of the threshing part of the baler 100, which can make the cut stubble of the straw opposite to the position of the straw arranging mechanism, so that the cut stubble is easier to be leveled, facilitating baling. The arranged straw gradually converges and is compressed by the baling mechanism 38, and finally is baled by the baling mechanism 38 and the tying mechanism 24. The whole process is automatically continuous, greatly reducing the labor intensity of manual straw recycling, with high recycling efficiency. The recycled straw forms bundles, which are convenient for storage and transportation.

[0042] Further, the baler 100 further includes a power mechanism. The power mechanism is coaxially connected with the cutter pulley 3. The cutter pulley 3 is connected to the threshing part pulley 1 by belt A2. When the baler 100 works, the power of the threshing part pulley 1 is transmitted to the cutter pulley 3 through belt A2. When the cutter pulley 3 rotates, it drives the power mechanism coaxially connected with the cutter pulley 3, and then transmits the power to each mechanism of the baler 100 through the power mechanism. The whole baler 100 can directly complete the work of harvesting → threshing → straw baling without additional power, with multiple functions in one machine, simple structure and low energy consumption.

[0043] Furthermore, the power mechanism includes: a baler driving wheel 4, a belt B5, a sprocket A6, a connecting rod A7, a chain A8, a sprocket B9 and a baler pulley 10, the baler driving wheel 4 is coaxially connected to the grass cutter pulley 3, the baler driving wheel 4 is connected to the baler pulley 10 through the belt B5, the baler pulley 10 is coaxially connected to the sprocket B9, the sprocket B9 is connected to the sprocket A6 through the chain A8, the sprocket A6 is connected to the grass-pulling mechanism through the first transmission mechanism, the sprocket B9 is connected to the baling mechanism 38 through the second transmission mechanism, the sprocket A6 is connected to the straw sorting mechanism through the connecting rod A7, and the grass cutter pulley 3 drives the baler driving wheel 4 to rotate synchronously with the threshing unit pulley 1, and the baler driving wheel 4 rotates When the baler pulley 10 rotates synchronously, the baler pulley 10 rotates and drives the sprocket B9 to rotate synchronously. When the sprocket B9 rotates, it transmits power to the sprocket A6 through the chain A8. At the same time, when the sprocket B9 rotates, it transmits power to the baling mechanism 38 through the second transmission mechanism. During the operation of the baling mechanism 38, the power is transmitted to the knotting mechanism 24 through the chain B28. The sprocket A6 transmits power to the straw sorting mechanism through the connecting rod A7, so that the kinetic energy of the threshing part is transmitted to each mechanism of the baler 100 in turn through the power mechanism, so as to realize the continuous operation of harvesting → threshing → baling. Each mechanism is relatively independent and cooperates with each other. There is no need for a complicated control system. Continuous automatic operation can be achieved through simple mechanical connection. The equipment cost is low and the reliability is good.

[0044] Furthermore, the first transmission mechanism includes: a hexagonal shaft tube A15 and a hexagonal shaft A20, one end of the hexagonal shaft tube A15 is connected to the sprocket A6, and the other end of the hexagonal shaft tube A15 is inserted into the hexagonal shaft A20, and the hexagonal shaft A20 can move back and forth along its axis for adjustment, and the other end of the hexagonal shaft A20 is connected to a claw mechanism A22 in the grass-moving mechanism through a universal joint A21, and the hexagonal shaft A20 can move back and forth along its axis for adjustment, so that the claw mechanism A22 connected to the universal joint A21 at the other end thereof can move the straw discharged by the harvester to the straw sorting mechanism for sorting, and then collect and squeeze it through the baling mechanism 38, and finally baling it through the baling mechanism 38 and the knotting mechanism 24, and the moving range of the claw mechanism A22 can be effectively adjusted by adjusting the position where the hexagonal shaft A20 is inserted into the hexagonal shaft tube A15 to adapt to straws of different lengths, with better adaptability.

[0045] Further, the second transmission mechanism includes: a hexagonal shaft tube B39 and a hexagonal shaft B37. One end of the hexagonal shaft tube B39 is connected to a sprocket B9. The other end of the hexagonal shaft tube B39 has the hexagonal shaft B37 inserted therein. The hexagonal shaft B37 can move back and forth along its axis for adjustment. The other end of the hexagonal shaft B37 is connected to a sprocket F34 through a universal joint B35. The second transmission mechanism can adjust the position of the hexagonal shaft B37 inserted into the hexagonal shaft tube B39 as needed. By changing the position of the hexagonal shaft B37 inserted into the hexagonal shaft tube B39, the position of the bundling mechanism 38 connected thereto can be adjusted, so that the bundling mechanism 38 can be adjusted according to different straw lengths and different bundling rope positions, and the adaptability is better.

[0046] Further, the straw arranging mechanism includes: a connecting rod B18, a connecting rod C19, a swing arm A12, a swing arm B13, a swing arm bearing seat 14, and an arranging plate 11. The swing arm A12 and the swing arm B13 are respectively installed on the swing arm bearing seat 14 through rotating shafts. The swing arm bearing seat 14 is fixedly connected to the baler frame. The arranging plate 11 is respectively connected to the same ends of the swing arm A12 and the swing arm B13. The swing arm A12 and the swing arm B13 are respectively hinged to both ends of the connecting rod C19. The swing arm A12 is hinged to one end of the connecting rod B18. The other end of the connecting rod B18 is hinged to a swing arm 17. The swing arm 17 is connected to a hexagonal shaft C16. The hexagonal shaft C16 is connected to a sprocket A6 through a connecting rod A7. When the hexagonal shaft C16 rotates, it drives the swing arm 17 to rotate. By driving the swing rod mechanism formed by the swing arm 17, the connecting rod B18, and the connecting rod C19, the swing arm A12 and the swing arm B13 are forced to reciprocate, so that the arranging plate 11 connected to the swing arm A12 and the swing arm B13 reciprocates. The surface of the arranging plate 11 faces the straw stubble part. The upper surface of the swing arm bearing seat 14 serves as the supporting surface for the straw. The arranging plate 11 reciprocally pats the straw stubble part and combines with the swing arm bearing seat 14 to form the straw into a shape. The swing rod mechanism formed by the swing arm 17, the connecting rod B18, and the connecting rod C19 converts the rotational motion of the hexagonal shaft C16 into the reciprocating motion of the swing arm A12 and the swing arm B13. The structural design is ingenious. At the same time, since the hexagonal shaft C16 used to drive the swing rod mechanism formed by the swing arm 17, the connecting rod B18, and the connecting rod C19 is connected to the sprocket A6 through the connecting rod A7, and the power at the sprocket A6 is respectively transmitted to the weed pushing mechanism and the bundling mechanism 38 through the first transmission mechanism and the second transmission mechanism. Therefore, the straw arranging mechanism cooperates with the weed pushing mechanism and the bundling mechanism 38 and acts synergistically, further improving the bundling effect of the straw.

[0047] Further, arc-shaped holes for the movement tracks of the swing arm A12 and the swing arm B13 are formed on the surface of the swing arm bearing seat 14. By forming the arc-shaped holes for the movement tracks of the swing arm A12 and the swing arm B13 on the surface of the swing arm bearing seat 14, it is ensured that the swing arm A12 and the swing arm B13 operate along the set tracks. Then, the reciprocating movement path and amplitude of the leveling plate 11 are controlled through the movement paths of the swing arm A12 and the swing arm B13, making the stubble more leveled, which is convenient for baling. At the same time, when the swing arm A12 and the swing arm B13 move along the arc-shaped holes, it can effectively avoid the phenomenon that the movement tracks of the swing arm A12 and the swing arm B13 deviate due to the impact when the leveling plate 11 reciprocally pats the stubble part of the straw, and the stability of the whole structure is better.

[0048] Further, the sprocket F34 in the second transmission mechanism is connected to the sprocket E29 through the chain C33. The sprocket E29 is connected to the input shaft 321 of the gearbox 32. The output shaft 322 of the gearbox 32 is connected to the baling mechanism 38. The gearbox 32 is connected to the chain box A25 through the transmission shaft B31. The chain box A25 includes a sprocket C26, a sprocket D30, and a chain B28. The transmission shaft B31 is connected to the sprocket D30. The sprocket D30 is connected to the sprocket C26 through the chain B28. The sprocket C26 is connected to the knotting mechanism 24 and the pawl mechanism B23 through the transmission shaft A27. The second transmission mechanism transmits power to the sprocket E29 through the sprocket F34, then transmits it to the gearbox 32 through the sprocket E29, and finally transmits it to the baling mechanism 38 through the gearbox 32. At the same time, the gearbox 32 also transmits power to the chain box A25 through the transmission shaft B31, and then transmits it to the knotting mechanism 24 and the pawl mechanism B23 through the chain box A25. The knotting mechanism 24 bales the straw, and then the pawl mechanism B23 discharges the baled straw from the baler 100.

[0049] Further, the pawl mechanism B23 is connected to the transmission shaft A27 through a connecting rod 40. One end of the connecting rod 40 is fixedly connected to the pawl mechanism B23, and the other end of the connecting rod 40 is connected to the transmission shaft A27. When the transmission shaft A27 rotates, it drives the connecting rod 40 to rotate. When the connecting rod 40 rotates, it drives the pawl mechanism B23 to reciprocate, so as to remove the baled straw from the baler 100. The transmission shaft A27 serves as the power shaft of the knotting mechanism 24 on the one hand and the power shaft of the pawl mechanism B23 on the other hand, coordinating the knotting mechanism 24 and the pawl mechanism B23 to work continuously together.

[0050] Further, the bundling mechanism 38 includes a hay pressing mechanism 41 and a bundling device 42. The hay pressing mechanism 41 includes a hay pressing arm 411 and a connecting rod mechanism 412 for driving the reciprocating movement of the hay pressing arm 411. The connecting rod mechanism 412 includes a driving connecting rod 413, an intermediate connecting rod 414, and a driven connecting rod 415. One end of the driving connecting rod 413 is connected to the output shaft 322 of the gearbox 32, the other end of the driving connecting rod 413 is connected to one end of the intermediate connecting rod 414, the other end of the intermediate connecting rod 414 is connected to one end of the driven connecting rod 415, the other end of the driven connecting rod 415 is hinged to the outer shell of the gearbox 32, the hay pressing arm 411 is fixed to the end of the intermediate connecting rod 414. The bundling device 42 includes a baffle rod 421, a bundler 422, and a twine threading part 423. One end of the baffle rod 421 is connected to a transmission mechanism 424 in the gearbox 32 through an adjusting plate 425. A plurality of adjusting holes 426 are provided on the adjusting plate 425. The baffle rod 421 is fixedly connected to the adjusting plate 425 through the adjusting holes 426. The transmission mechanism 424 is connected to the bundler 422 and the twine threading part 423. When the bundling mechanism 38 performs a bundling operation, the hay pressing arm 411 in the hay pressing mechanism 41 gradually gathers and squeezes the straw during the reciprocating movement. As the diameter of the hay bale increases, the hay bale continuously squeezes the baffle rod 421. Therefore, the squeezing force transmitted to the baffle rod 421 gradually increases. When it increases to a set value, the baffle rod 421 starts to rotate. When the baffle rod 421 rotates, it triggers the transmission mechanism 424 in the gearbox 32 to start moving. When the transmission mechanism 424 moves, it drives the bundler 422 and the twine threading part 423 to work for bundling. By connecting the baffle rod 421 to different adjusting holes 426 on the adjusting plate 425, it is possible to increase or decrease the space of the hay bale, that is, to increase the diameter of the hay bale, so as to realize bundling straw with different diameters according to the different needs of users.

[0051] The working principle of the present invention: When the cutter pulley 3 rotates with the threshing part pulley 1, it drives the baler driving wheel 4 to rotate synchronously. When the baler driving wheel 4 rotates, it drives the baler pulley 10 to rotate synchronously. When the baler pulley 10 rotates, it drives the sprocket B9 to rotate synchronously. When the sprocket B9 rotates, it transmits power to the sprocket A6 through the chain A8. At the same time, when the sprocket B9 rotates, it transmits power to the bundling mechanism 38 through the second transmission mechanism. During the operation of the bundling mechanism 38, power is transmitted to the knotting mechanism 24 through the chain B28. The sprocket A6 transmits power to the straw arranging mechanism through the connecting rod A7. The threshed straw is dialed into the area of the straw arranging mechanism through the straw dialing mechanism. The straw arranging mechanism arranges the stubble part of the straw. The arranged straw gradually gathers and squeezes through the bundling mechanism, and finally is bundled through the bundling mechanism and the knotting mechanism. The whole process is automatically continuous, greatly reducing the labor intensity of manual straw recycling, having high recycling efficiency, and the recycled straw forms a bundle, which is convenient for storage and handling.
