Description

Technical Field

[0001] This invention relates to the field of baler technology, and in particular to a straw feeding device and method for a baler. Background Technology

[0002] A baler is an agricultural machine that compresses loose materials such as crop straw and forage into tight, regular bales. It is widely used in straw recycling, livestock feed storage, and biomass fuel production, significantly improving transportation efficiency, reducing storage space, and lowering fire risk. Based on the shape of the finished product, balers are divided into square balers and round balers. Round balers produce cylindrical bales, are highly adaptable to terrain, have low equipment costs, and are suitable for hilly areas or small plots of land.

[0003] Existing technologies, such as a utility model of a baler picker without a protective ring (authorization number CN221606167U), have a simple overall structure. They enable quick replacement of the spring teeth while ensuring the teeth are firmly fixed during use, preventing them from easily falling off and improving performance.

[0004] Traditional balers commonly suffer from uneven straw feeding, resulting in inconsistent bale density and affecting storage and transportation efficiency. Currently, there is a lack of a straw feeding device and method for balers that allows the pick-up device to move the straw from the center outwards during collection, spreading it evenly and preventing it from being thicker in the middle and thinner at the edges.

[0005] Therefore, in order to address the above problems, a straw feeding device and method for a baler are proposed to solve these problems. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by developing a straw feeding device and method for balers. The device involves a pickup rod that moves periodically along a D-shaped groove, contacting the straw and causing it to move along a straw guide. After the flip plate is vertically inserted into the straw from top to bottom, it flips to both sides, causing the straw to move from the center to the sides. A pressure plate then presses the straw downwards, spreading it evenly and preventing it from being thicker in the middle and thinner at the sides.

[0007] The technical solution to the problem solved by this invention is as follows: This invention provides a straw feeding device and method for a baler, comprising: a picker and a picker frame, wherein the picker is mounted on the picker frame; the picker frame includes symmetrical covers, each of which is connected to symmetrical mounting crossbars, and each of the symmetrical mounting crossbars is connected to a set of straw guide covers; during use, the picker frame provides stable support. The symmetrical covers not only provide a reliable bearing connection position for the picker shaft, but also provide a certain degree of protection for the internal structure. The mounting crossbars connect the covers and the straw guide covers, which guide the picked-up straw to a suitable position, ensuring that the straw smoothly enters the subsequent baling process. The pickup device includes a pickup shaft, which is bearing-connected to symmetrical housings. At least one end of the pickup shaft is connected to a pulley. The pickup shaft is connected to symmetrical mounting discs, each of which is connected to a set of evenly distributed mounting slots. Each mounting slot is bearing-connected to a mounting shaft, and each mounting shaft passes through one of the symmetrical mounting discs. Each mounting shaft is connected to a set of torsion springs, and each torsion spring is connected to a symmetrical pickup rod. The symmetrical housings are connected to D-blocks, through which the pickup shaft passes. Each D-block has a D-groove, and each mounting shaft is connected to a symmetrical swing arm. Each swing arm is connected to a track block, and each track block is positioned within a corresponding D-groove. The pickup shaft rotates under the drive of the pulley, which in turn rotates the mounting discs. The mounting slots on the mounting discs provide mounting space for the mounting shafts. The torsion springs on the mounting shafts cooperate with the pickup rods, allowing the pickup rods to swing flexibly when encountering grass, thus picking up the grass more effectively. When the mounting plate rotates, the swing arm moves with the mounting shaft, and the track block moves within the D-slot, ensuring the stability of the pickup rod's trajectory during pickup and improving pickup efficiency and quality. When the pickup rod encounters a large stone, it elastically swings, and the torsion spring twists to prevent large stones from being picked up into the pickup unit. After the stone is no longer in contact, the torsion spring returns to its original position, allowing the pickup rod to return to its original position.

[0008] As an optimization, an auxiliary feeding assembly is also included. This assembly comprises a feeding cover connected to a main shaft. The main shaft is rotatably connected to symmetrical machine covers, each symmetrical machine cover being rotatably connected to a spring rod. The free ends of the symmetrical spring rods are rotatably connected to the feeding cover. The feeding cover is connected to symmetrical round head plates, each symmetrical round head plate bearing an auxiliary shaft. Spiral feeding blades can be installed on the auxiliary shaft. When the main shaft rotates to feed straw, a large amount of straw will cause the feeding cover to move. The movement of the feeding cover causes corresponding extension and retraction of the spring rods. When the amount of straw fed decreases, the spring rods return to their original position. When the auxiliary shaft rotates, the feeding blades also rotate, guiding the straw more smoothly to the subsequent baling process, further improving feeding efficiency and ensuring the baler can continuously and stably obtain straw for baling operations.

[0009] As an optimization, each end of the auxiliary shaft is connected to a set of mounting plates, and each mounting plate is connected to a set of mounting shells. Each end of the grass feed cover is connected to a set of annular plates, and each annular plate is connected to a wedge block. Each mounting shell is connected to a drive rack via a spring, and each drive rack is connected to a ball joint rod. Each spring is looped around a corresponding ball joint rod, and each ball joint rod passes through a corresponding mounting shell. Each ball joint rod matches a corresponding wedge block. Each mounting shell is connected to a circular tube shaft via a bearing, and each circular tube shaft is connected to a drive gear. Each drive gear meshes with a corresponding drive rack, and each circular tube shaft is connected to a flap. When the baler is started using the feeding device, the ball head rod rotates with the auxiliary shaft. As the ball head rod moves along the wedge block, both ends of the wedge block are arc-shaped, and the bottom of the arc is flush with the circular ring plate. When the ball head rod rotates, it moves along the surface of the wedge block, realizing the extension and retraction of the ball head rod. Because the ball head rod is connected to the drive rack, the ball head rod will push the drive rack to move inside the mounting housing after being subjected to force. The drive rack meshes with the drive gear, which is connected to the circular tube shaft. The circular tube shaft is connected to the flap, which ultimately realizes the rotation of the flap. The flap inserts into the straw from top to bottom in a blade shape. The rotation of the flap moves the straw to both sides, ensuring the stability and efficiency of the baler's feeding process.

[0010] As an optimization, each of the driving racks is connected to a driven rack, each driven rack meshes with a driven gear, each driven gear is connected to a threaded cylinder, each threaded cylinder is bearing-connected to a corresponding cylindrical shaft, each threaded cylinder is threadedly connected to a screw, each screw is connected to a U-plate, each U-plate is rotatably connected to a power arm, each power arm is rotatably connected to a pressure plate, and each pressure plate is rotatably connected to a corresponding flap. When the driving rack moves within the mounting housing, because the driving rack is connected to the driven rack, it drives the driven rack to move synchronously. The movement of the driven rack causes the driven gear it meshes with to rotate, and the rotation of the driven gear in turn drives the connected threaded cylinder to rotate. Because the threaded cylinder is threadedly connected to the screw, when the threaded cylinder rotates, the screw will move linearly along the axial direction of the threaded cylinder. The linear motion of the screw drives the connected U-plate to move. The movement of the U-plate causes the rotating power arm to swing. The swing of the power arm then drives the pressure plate to rotate. Finally, the rotation of the pressure plate helps the flip plate to better move the straw. The pressure plate squeezes the straw diagonally downwards, further ensuring the stability and efficiency of the straw feeding process of the baler.

[0011] As an optimization, a transmission assembly is also included. This assembly comprises at least one driving pulley, whose central shaft is connected to a corresponding pulley. The central shaft of the driving pulley is bearing-connected to a lower support rod, which in turn is bearing-connected to a double-rotating pulley. The double-rotating pulley is bearing-connected to an upper support rod, which is bearing-connected to the central shaft of the driven pulley. A lower synchronous belt surrounds the driving pulley and one of the double-rotating pulleys, while an upper synchronous belt surrounds the driven pulley and the other of the double-rotating pulleys. The central shaft of the driven pulley is bearing-connected to a corresponding round-head plate, and its central shaft is connected to a drive gear. This drive gear meshes with an actuating gear, which is connected to an auxiliary shaft. In actual operation, the pulleys begin to rotate under power. Since the driving pulley's central shaft is connected to the pulley, it drives the driving pulley to rotate as well. As the driving pulley rotates, the lower synchronous belt moves accordingly, thereby driving the double-rotating pulleys to rotate. The rotation of the double-rotating pulleys, in turn, drives the driven pulley to rotate via the upper synchronous belt. The rotation of the driven pulley causes the drive gear to rotate synchronously. The drive gear meshes with the actuator gear. The rotation of the drive gear drives the actuator gear to rotate, and the actuator gear is connected to the auxiliary shaft. Ultimately, through this series of transmissions, the auxiliary shaft is driven, which helps the entire baler to better complete the straw feeding work with the straw feeding device.

[0012] As an optimization, at least one of the machine covers is connected to a T-axis via a block. The T-axis passes through a T-rod, which in turn passes through a slider. The dual-wheel bearing connects to the slider. The slider can move vertically and horizontally. When the entire device is running, the feed cover oscillates as the amount of straw fed changes, allowing the slider to adjust its position. The T-rod moves along the T-axis, ensuring the stability and flexibility of the entire connection structure. The dual-wheel bearing connects to the slider. During the rotation of the dual wheels, the slider not only provides support but also adapts to the forces generated by the rotation of the dual wheels to a certain extent, ensuring smooth rotation of the dual wheels and thus guaranteeing the smooth operation of the straw feeding device for the baler.

[0013] As an optimization, the T-axis is connected to the T-rod via a transverse spring, which loops around the T-axis. The transverse spring provides a buffer when the T-rod moves along the T-axis. When a sudden increase or decrease in the feed rate causes changes in the swing amplitude of the feed hood, thus altering the speed and force of the T-rod's movement, the transverse spring absorbs and releases some energy, preventing excessive impact between the T-rod and the T-axis, reducing component wear, and extending the service life of the entire connection structure. Simultaneously, the transverse spring looping around the T-axis ensures a stable connection between the transverse spring, the T-axis, and the T-rod without excessively hindering the normal movement of the T-rod on the T-axis. This ensures that the entire device can flexibly adjust according to changes in the feed rate during operation, maintaining a stable working state at all times.

[0014] As an optimization, each of the pickup rods is positioned within the corresponding areas formed by the two guide hoods. This allows the pickup rods to perform pickup operations more precisely within the area defined by the guide hoods, preventing grass from scattering into other non-working areas and improving pickup efficiency. Simultaneously, the areas formed by the two guide hoods provide a relatively independent and stable working space for the pickup rods, reducing interference from external factors and further ensuring the stability and reliability of the grass feeding device.

[0015] A method for feeding straw into a straw feeding device for a baler includes the following steps: S1: The cover is installed on the baler, and this device replaces the existing pickup part; S2: Use a timing belt to connect the pulley to a power source, such as a vehicle engine; S3: During baling, the pulley drives the pickup shaft to rotate, causing the track block to move along the D-shaped groove, and the pickup rod to move periodically, so that it contacts the grass and drives the grass to move along the grass guide cover; S4: The auxiliary shaft rotates in the opposite direction to the picking shaft. After the flip plate is vertically inserted into the grass, it flips to both sides, causing the grass to move from the middle to both sides. The pressure plate presses the grass downwards to spread it out, avoiding a thicker middle and thinner sides.

[0016] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects: (1) This device achieves uniform spreading of straw by using a flipping plate and a pressing plate. During the baling process, the flipping plate and pressing plate are first inserted vertically into the straw pile, and then flipped to both sides. This action causes the straw to be dispersed from the middle to both sides. At the same time, the pressing plate squeezes the straw downwards, further ensuring the uniform distribution of straw in the device, effectively avoiding the uneven situation of the straw being thick in the middle and thin on both sides when baling, thereby improving the quality and efficiency of baling.

[0017] (2) This device uses synchronous belt drive to transmit power, which makes the operation of various components such as the pickup shaft and auxiliary shaft coordinated and consistent, ensuring the stability and accuracy of the baling operation. When the straw inlet cover swings, it will not affect the transmission, thus improving the working efficiency of the entire straw inlet device for the baler. The device uses a T-shaft, T-rod and slider. When the straw inlet cover swings, the T-shaft can provide stable support, the T-rod moves accordingly with the swing of the straw inlet cover, and the slider slides smoothly on the T-rod. The three components work together to effectively ensure the stability and flexibility of the connection of each component during the swing of the straw inlet cover, reduce the friction and resistance caused by the swing, make the straw feeding process smoother, and thus improve the working performance of the entire straw inlet device for the baler.

[0030] like Figures 1 to 9As shown in Embodiment 1: A straw feeding device for a baler includes: a picker 3 and a picker frame 2. The picker 3 is mounted on the picker frame 2. The picker frame 2 includes symmetrical covers 21, each symmetrical cover 21 connected to symmetrical mounting crossbars 23, and each symmetrical mounting crossbar 23 connected to a set of straw guide covers 22. During use, the picker frame 2 provides stable support. The symmetrical covers 21 not only provide a reliable bearing connection position for the picker shaft 38 but also provide some protection for the internal structure. The mounting crossbars 32 connect the covers 21 and the straw guide covers 22, which guide the picked-up straw to a suitable position, ensuring that the straw smoothly enters the subsequent baling process. The pickup device 3 includes a pickup shaft 38, which is bearing-connected to the symmetrical housing 21. At least one end of the pickup shaft 38 is connected to a pulley 37. The pickup shaft 38 is connected to symmetrical mounting discs 31. The symmetrical mounting discs 31 are respectively connected to a set of evenly distributed mounting slots 32. Each mounting slot 32 is bearing-connected to a mounting shaft 39. Each mounting shaft 39 passes through the symmetrical mounting disc 31. Each mounting shaft 39 is connected to a set of torsion springs 33. Each torsion spring 33 is connected to a symmetrical pickup rod 34. The symmetrical housing 21 is respectively connected to D-shaped blocks 310. The pickup shaft 38 passes through the symmetrical D-shaped blocks 310. The symmetrical D-shaped blocks 310 are respectively provided with D-shaped grooves 311. Each mounting shaft 39 is connected to a symmetrical swing arm 36. Each swing arm 36 is connected to a track block 35. Each track block 35 is respectively set in the corresponding D-shaped groove 311. The pickup shaft 38 rotates under the drive of the pulley 37, which in turn drives the mounting plate 31 to rotate. The mounting groove 32 on the mounting plate 31 provides mounting space for the mounting shaft 39. The torsion spring 33 on the mounting shaft 39 cooperates with the pickup rod 34, allowing the pickup rod 34 to swing flexibly when encountering grass, thus picking up grass more effectively. When the mounting plate 31 rotates, the swing arm 36 moves with the mounting shaft 39, and the track block 35 moves within the D-shaped groove 311, ensuring the stability of the movement trajectory of the pickup rod 34 during the pickup process and improving pickup efficiency and quality. When the pickup rod 34 encounters a large stone, it elastically swings, and the torsion spring 33 twists, preventing large stones from being picked up into the pickup device 3. After the stone is removed from contact, the torsion spring 33 returns to its original position, allowing the pickup rod 34 to return to its original position.

[0031] Each of the aforementioned pickup rods 34 is respectively positioned within the area formed by the two corresponding grass guide covers 22. This allows the pickup rods 34 to perform pickup operations more precisely within the area defined by the grass guide covers 22, preventing grass from scattering into other non-working areas and improving pickup efficiency. Simultaneously, the area formed by the two grass guide covers 22 provides a relatively independent and stable working space for the pickup rods 34, reducing interference from external factors and further ensuring the stability and reliability of the grass feeding device.

[0032] The workflow of this embodiment is as follows: The shroud 21 is mounted on the baler. This device replaces the existing pickup section and uses a timing belt to connect the pulley 37 to a power source, such as a vehicle engine.

[0033] During baling, the pulley 37 drives the pickup shaft 38 to rotate, causing the track block 35 to move along the D-shaped groove 311. This causes the pickup rod 34 to move periodically, contacting the grass and moving the grass along the grass guide cover 22. The D-shaped groove 311 includes a semi-circular part and a straight part. When the track block 35 moves along the vertical part, it drives the swing arm 36 to swing. The swing arm 36 drives the mounting shaft 39 to rotate, and the mounting shaft 39 drives the torsion spring 33 and the pickup rod 34 to swing, making it easier for the pickup rod 34 to contact the grass and move the grass. When the pickup rod 34 encounters a large stone, it elastically swings, and the torsion spring 33 twists to prevent large stones from being picked up into the pickup device 3. After the contact with the stone is broken, the torsion spring 33 returns to its original position, causing the pickup rod 34 to return to its original position.

[0034] Example 2: This example is a further elaboration based on Example 1, and also includes an auxiliary grass feeding component 1. The auxiliary grass feeding component 1 includes a grass feeding cover 13, which is connected to a main shaft 11. The main shaft 11 is rotatably connected to a symmetrical machine cover 21. The symmetrical machine covers 21 are rotatably connected to spring rods 12, and the free ends of the symmetrical spring rods 12 are rotatably connected to the grass feeding cover 13. The grass feeding cover 13 is connected to symmetrical round head plates 14, and the symmetrical round head plates 14 are respectively bearing connected to an auxiliary shaft 15. Spiral feed blades can be installed on the auxiliary shaft 15. When the main shaft 11 rotates to feed straw, when the amount of straw fed is large, it will drive the straw feeding cover 13 to move. The movement of the straw feeding cover 13 causes the spring rod 12 to extend and retract accordingly. When the amount of straw fed decreases, the spring rod 12 returns to its original position. When the auxiliary shaft 15 rotates, the feed blades also rotate, which can guide the straw more smoothly to the subsequent baling process, further improve the efficiency of straw feeding, and ensure that the baler can continuously and stably obtain straw for baling operations.

[0035] It also includes a transmission assembly 4, which includes at least one drive pulley 413. The central shaft of the drive pulley 413 is connected to the corresponding pulley 37. The central shaft of the drive pulley 413 is bearing-connected to a lower support rod 48. The lower support rod 48 is bearing-connected to a double rotating wheel 412. The double rotating wheel 412 is bearing-connected to an upper support rod 45. The upper support rod 45 is bearing-connected to the central shaft of the driven pulley 46. A lower synchronous belt 49 surrounds the drive pulley 43 and one of the double rotating wheels 412. An upper synchronous belt 47 surrounds the driven pulley 46 and the other of the double rotating wheels 412. The central shaft of the driven pulley 46 is bearing-connected to the corresponding round head plate 14. The central shaft of the driven pulley 46 is connected to a power gear 43. The power gear 43 meshes with an actuating gear 44. The actuating gear 44 is connected to the auxiliary shaft 15. In actual operation, pulley 37 begins to rotate under power. Since the central shaft of drive pulley 413 is connected to pulley 37, it will drive drive pulley 413 to rotate as well. When drive pulley 413 rotates, lower synchronous belt 49 moves accordingly, which in turn drives double pulley 412 to rotate. The rotation of double pulley 412 then drives driven pulley 46 to rotate through upper synchronous belt 47. The rotation of driven pulley 46 will cause drive gear 43 to rotate synchronously. Drive gear 43 meshes with actuator gear 44, and the rotation of drive gear 43 will drive actuator gear 44 to rotate. Actuator gear 44 is connected to auxiliary shaft 15. Finally, through this series of transmissions, the auxiliary shaft 15 is driven, assisting the entire baler's straw feeding device to better complete the straw feeding work.

[0036] The workflow of this embodiment is as follows: When pulley 37 rotates, it drives pulley 413 to rotate, causing lower timing belt 49 to move accordingly, which in turn drives double pulley 412 to rotate. The rotation of double pulley 412 then drives driven pulley 46 to rotate via upper timing belt 47. The rotation of driven pulley 46 causes drive gear 43 to rotate synchronously. Drive gear 43 meshes with actuating gear 44, and the rotation of drive gear 43 drives actuating gear 44 to rotate, thereby causing auxiliary shaft 15 to rotate. When the amount of grass fed is large, grass feed cover 13 swings, causing grass feed shaft 11 to rotate. Grass feed cover 13 drives round head plate 14 to swing, which in turn drives auxiliary shaft 15, drive gear 43, and actuating gear 44 to swing. Drive gear 43 drives driven pulley 46 to swing, which in turn drives double pulley 412, upper support rod 45, and upper timing belt 47 to swing. Double pulley 412 drives lower support rod 48 and lower timing belt 49 to swing.

[0037] Example 3: This example further elaborates on Example 2. A set of mounting plates 16 are connected to both ends of the auxiliary shaft 15. Each mounting plate 16 is connected to a set of mounting shells 19. A set of annular plates 17 are connected to both ends of the grass feed cover 11. Each annular plate 17 is connected to a wedge block 18. A drive rack 119 is connected to each mounting shell 19 via a spring 118. Each drive rack 119 is connected to a ball joint rod 115. Each spring 118 is looped around a corresponding ball joint rod 115. Each ball joint rod 115 passes through a corresponding mounting shell 19. Each ball joint rod 115 matches a corresponding wedge block 18. Each mounting shell 19 is connected to a circular tube shaft 121 via a bearing. Each circular tube shaft 121 is connected to a drive gear 122. Each drive gear 122 meshes with a corresponding drive rack 119. Each circular tube shaft 121 is connected to a flap 110. When the baler is started with the feeding device, the ball head rod 115 rotates with the auxiliary shaft 15. When the ball head rod 115 moves along the wedge block 18, both ends of the wedge block 18 are arc-shaped, and the bottom of the arc is flush with the ring plate 17. When the ball head rod 115 rotates, it moves along the surface of the wedge block 18, realizing the extension and retraction of the ball head rod 15. Because the ball head rod 115 is connected to the drive rack 119, the ball head rod 15 will push the drive rack 119 to move in the mounting shell 19 after being subjected to force. The drive rack 119 is engaged with the drive gear 122. The drive gear 122 is connected to the round tube shaft 121, and the round tube shaft 121 is connected to the flap 110, which finally realizes the rotation of the flap 110, so that the flap 110 inserts into the straw from top to bottom in a blade shape. The rotation of the flap 110 moves the straw to both sides, ensuring the stability and efficiency of the baler's feeding process.

[0038] The workflow of this embodiment is as follows: When the auxiliary shaft 15 rotates, it drives the mounting shell 19 and the ball head rod 115 to rotate. The ball head rod 115 moves along the annular plate 17 and the wedge block 18. When the ball head rod 115 contacts the wedge block 18 and moves along the surface of the wedge block 18, under the elastic action of the spring 118, the active rack 119 moves, driving the active gear 122 and the round tube shaft 121 to rotate, so that the flip plate 110 is inserted into the straw from top to bottom in a blade shape. The flip plate 110 rotates and moves the straw to both sides, ensuring the stability and efficiency of the straw feeding process of the baler.

[0039] Example 4: This example further elaborates on Example 3. Each driving rack 119 is connected to a driven rack 116, each driven rack 116 meshes with a driven gear 117, each driven gear 117 is connected to a threaded cylinder 120, each threaded cylinder 120 is bearing-connected to a corresponding cylindrical shaft 121, each threaded cylinder 120 is threadedly connected to a screw 114, each screw 114 is connected to a U-plate 113, each U-plate 113 is rotatably connected to a power arm 112, each power arm 112 is rotatably connected to a pressure plate 111, and each pressure plate 111 is rotatably connected to a corresponding flap 110. When the driving rack 119 moves within the mounting housing 19, because the driving rack 119 is connected to the driven rack 116, it will drive the driven rack 116 to move synchronously. The movement of the driven rack 116 causes the driven gear 117, which meshes with it, to rotate. The rotation of the driven gear 117, in turn, drives the connected threaded cylinder 120 to rotate. Because the threaded cylinder 120 is threadedly connected to the screw 114, the screw 114 will move linearly along the axial direction of the threaded cylinder 120 when the threaded cylinder 120 rotates. The linear motion of the screw 114 drives the connected U-plate 113 to move. The movement of the U-plate 113 causes the rotating power arm 112 to swing. The swing of the power arm 112 drives the pressure plate 111 to rotate. Finally, the rotation of the pressure plate 111 assists the flip plate 110 in better manipulating the straw. The pressure plate 111 squeezes the straw diagonally downwards, further ensuring the stability and efficiency of the straw feeding process of the baler.

[0040] The workflow of this embodiment is as follows: When the driving rack 119 moves, it drives the driven rack 116 to move, which in turn drives the driven gear 117 and the threaded cylinder 120 to rotate. The threaded cylinder 120 drives the screw 114 to move, which in turn drives the U-plate 113 to move. The U-plate 113 drives the power arm 112 to swing, which in turn drives the pressure plate 111 to rotate. Ultimately, the rotation of the pressure plate 111 assists the flip plate 110 in better maneuvering the straw. The pressure plate 111 squeezes the straw diagonally downwards, further ensuring the stability and efficiency of the baler's straw feeding process.

[0041] Example 5: This example further elaborates on Example 2. At least one of the machine covers 21 is connected to a T-axis 42 via a block. The T-axis 42 passes through a T-rod 410, and the T-rod 410 passes through a slider 411. The double rotating wheel 412 is connected to the slider 411 by a bearing. The slider 411 can move in the up-down and back-and-forth directions. When the entire device is running, the feeding cover 13 swings as the amount of straw fed changes, and the slider 411 can be adjusted in position. The T-rod 410 moves along the T-axis 42, ensuring the stability and flexibility of the entire connection structure. The double rotating wheel 412 is connected to the slider 411 by a bearing. During the rotation of the double rotating wheel 412, the slider 411 not only provides support but also adapts to the force generated by the rotation of the double rotating wheel 412 to a certain extent, ensuring the smooth rotation of the double rotating wheel 412 and thus ensuring the smooth operation of the straw feeding device for the baler.

[0042] The T-axis 42 is connected to the T-rod 410 via a transverse spring 41, which loops around the T-axis 42. The transverse spring 41 provides a buffering force when the T-rod 410 moves along the T-axis 42. When a sudden increase or decrease in the feed rate causes a change in the swing amplitude of the feed cover 13, thus altering the movement speed and force of the T-rod 410, the transverse spring 41 can absorb and release some energy, preventing excessive impact between the T-rod 410 and the T-axis 42, reducing component wear, and extending the service life of the entire connection structure. Simultaneously, the transverse spring 41 looping around the T-axis 42 ensures a stable connection between the transverse spring 41, the T-axis 42, and the T-rod 410, without excessively hindering the normal movement of the T-rod 410 on the T-axis 42. This ensures that the entire device can flexibly adjust according to changes in the feed rate during operation, maintaining a stable working state at all times.

[0043] The workflow of this embodiment is as follows: When the double rotating wheel 412 moves, it drives the slider 411 to move along the T rod 410. The slider 411 drives the T rod 410 to move along the T axis 410. The T rod 410 drives the horizontal spring 41 to move.

[0044] A method for feeding straw into a straw feeding device for a baler includes the following steps: S1: The cover 21 is installed on the baler, and this device replaces the existing pickup part; S2: Use a timing belt to connect the pulley 37 to a power source, such as a vehicle engine; S3: When baling, the pulley 37 drives the pickup shaft 38 to rotate, causing the track block 35 to move along the D-shaped groove 311, causing the pickup rod 34 to move periodically, so that it contacts the grass, and drives the grass to move along the grass guide cover 22. S4: The auxiliary shaft 15 rotates in the opposite direction to the picking shaft 38. After the flip plate 110 is vertically inserted into the grass, it flips to both sides, so that the grass moves from the middle to both sides. The pressure plate 111 presses the grass downward to spread the grass out, so as to avoid the grass being thick in the middle and thin on both sides.

[0045] This device achieves uniform spreading of hay by employing a flipping plate 110 and a pressing plate 111. During the baling process, the flipping plate 110 and pressing plate 111 are first inserted vertically into the hay pile, and then flipped to both sides. This action causes the hay to disperse from the center to both sides. At the same time, the pressing plate 111 compresses the hay downwards, further ensuring the uniform distribution of the hay within the device. This effectively avoids the uneven distribution of hay, where it is thicker in the middle and thinner on the sides, thus improving the quality and efficiency of baling.

[0046] This device uses synchronous belt drive to transmit power, ensuring coordinated operation between components such as the pickup shaft and auxiliary shaft. This guarantees the stability and accuracy of the baling operation. Even when the feed hood 13 swings, it does not affect the transmission, improving the overall efficiency of the baler's feed device. Employing a T-shaft 42, T-rod 410, and slider 411, the T-shaft 42 provides stable support when the feed hood 13 swings. The T-rod 410 moves accordingly with the swing, and the slider 411 slides smoothly on the T-rod 410. The three components work together to effectively ensure the stability and flexibility of the connections between components during the swing of the feed hood 13, reducing friction and resistance caused by the swing, making the feed process smoother, and thus improving the overall performance of the baler's feed device.

Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
