Description

Technical Field

[0001] The invention belongs to the technical field of straw rolling and baling, and in particular relates to a rope winding mechanism for a round straw baler. Background Art

[0002] Straw baling and rope winding are a crucial step in the straw baling process. They bundle formed straw into compact bales, making them easier to transport, store, and process, while preventing the straw from scattering during handling. Common rope winding materials include nylon rope and polypropylene rope. Nylon rope offers high strength and good wear resistance, but is relatively expensive. Polypropylene rope is less expensive and possesses a certain strength and flexibility, meeting the needs of general straw baling. The working principle is as follows: After the straw baler compresses the straw into bales, the rope winding mechanism automatically wraps the rope around the bale, typically multiple times, and then uses a knotting device to tighten the rope at both ends to form a secure bundle.

[0003] The current method of rope winding of straw is as follows: the patent application with publication number: CN112243706A discloses a round grass baler with non-stop baling, which can effectively solve the problem of the prior art that the baler needs to stop moving forward each time it winds and ties the grass bales, which greatly increases the picking time and seriously reduces the baling efficiency. The technical solution is that a power speed change transmission mechanism is installed at the lower front end of the front box body of the chassis side panel, a storage chamber is provided at the front of the front box body, a compression chamber is provided at the rear of the front box body, a rope winding mechanism is installed at the upper part of the front box body, a hydraulic mechanism is installed at the chassis side panel, and a picking mechanism is installed at the bottom of the front box side panel at the non-chain end of the chassis side panel. The rope winding mechanism and the hydraulic mechanism are respectively connected to the electrical control system. The present invention has a novel and unique structure and stable and reliable performance. It can fundamentally solve the disadvantages of intermittent operation of round grass balers, greatly improve the working efficiency, and is an innovation in the operating method and device of round grass balers.

[0004] The rope winding mechanism includes a DC motor, an active lower rope roller, and a passive lower rope roller. The active lower rope roller is connected to the passive lower rope roller. One end of the DC motor of the active lower rope roller is equipped with an active lower rope roller sprocket, which is equipped with a DC motor sprocket. The active lower rope roller sprocket and the DC motor sprocket are connected by a lower rope roller chain. The DC motor drives the active lower rope roller to rotate, and the passive lower rope roller is equipped with a tying rope. The rope winding mechanism is installed on the upper part of the front box and is used to tie round grass bales. The active lower rope roller and the passive lower rope roller wind the rope around the grass bales.

[0005] In this winding method, the rope rotates and is wound around the straw bale. This winding method cannot achieve winding of the straw bale from beginning to end, but only winds around the middle, resulting in looseness. Summary of the Invention

[0031] This embodiment discloses a rope winding mechanism for a round straw baler, which is used for a rolling mechanism and is used for baling after the straw core rotates to form a bale. As the bale continues to rotate, the rope 35 is wound around the bale to complete the baling.

[0032] Under the action of this mechanism, the bale rotates and the rope is wound around it to achieve rope winding. It is worth noting that this solution only involves rope winding after the bale is formed, and does not involve the bale shaping or the pushing process after rope winding.

[0033] This round straw baler uses a rope winding mechanism, such as Figure 1 and Figure 2 As shown, the device comprises a frame 1, on which are mounted a fixed plate 2, a transmission system, and a rope winding platform 5. During operation, the rope winding platform 5, driven by the transmission system, reciprocates horizontally along the fixed plate 2, thereby wrapping a rope 35 around a straw bale. It is worth noting that the frame 1 merely serves as the rope winding mechanism for the baler, and this embodiment only includes the function of winding the rope around the outside of a straw bale. The formation of the straw bale is not covered by this embodiment. Furthermore, the device can be directly connected to an existing straw round baler by connecting the frame 1.

[0034] Among them, the rope winding platform 5, such as Figure 4 As shown, it includes a frame, a shaft 27, and a rope-splitting plate 10. The top of the frame is slidably mounted on the fixed plate 2. That is, the frame moves back and forth on the fixed plate 2 under the drive system. To improve the smoothness of the frame sliding on the fixed plate 2, a slider 21 is provided at the top of the frame. The fixed plate 2 is provided with a guide rail 22, and the slider 21 is slidably mounted within the guide rail 22.

[0035] The shaft 27 is located below the frame and is rotatably mounted on the rope winding platform 5 . The shaft 27 is hollow, and a rope passage 28 is provided in the hollow portion thereof. The rope passage 28 is provided through the shaft 27 in a height direction.

[0036] A rope winding roller 12 is mounted on the shaft 27. This roller is used to wind a thick rope. A rope winding groove 13 is provided on the outer wall of the roller 12, spirally extending from bottom to top. The thick rope can be wound from the bottom to the top of the roller 12 along the rope winding groove 13. A rope pressing roller 14 is mounted on the side of the roller 12. This roller 14 is rotatably connected to the rope winding platform 5, with a gap between the roller 14 and the roller 12. This pressure roller 14 compresses the thick rope on the roller 12, ensuring a smooth winding of the thick rope.

[0037] To facilitate winding the thick rope around the rope winding roller 12, a guide pulley 9 is mounted on the machine body and rotatably mounted there. An upper rope passage tube 24 and a lower rope passage tube 25 are located on the sides of the rope winding roller 12, both fixed to the rope winding platform 5. The front end of the upper rope passage tube 24 corresponds to the guide pulley 9, the rear end of the upper rope passage tube 24 corresponds to the bottom end of the rope winding groove 13, and the front end of the lower rope passage tube 25 corresponds to the thin rope pulley 11. The thick rope is wound around the guide pulley 9, passes through the guide pulley 9, enters the upper rope passage tube 24, and then enters the rope winding groove 13. It then winds along the rope winding groove 13 from the bottom of the rope winding roller 12 to the top.

[0038] A rope guide tube 23 is installed above the rope winding roller 12 and in conjunction with the rope winding groove 13. The rope guide tube 23 is also fixed to the rope winding platform 5. One end of the rope guide tube 23 corresponds to the top of the rope winding groove 13, and the other end is arranged toward the top of the rope channel 28. Therefore, the thick rope wound from the top of the rope winding groove 13 enters the rope guide tube 23, exits the rope guide tube 23, enters the rope channel 28, and then enters the bottom of the rope channel 28 along the rope channel 28.

[0039] The above is the process of winding the thick rope. In this embodiment, the guide rope wheel 9, the upper rope tube 24, the rope winding groove 13 and the guide rope tube 23 can smoothly guide the thick rope from the machine body into the straw bale, and the introduction process flow can avoid the phenomenon of jamming.

[0040] Below the rope winding roller 12 is a thin rope pulley 11, also mounted on a shaft 27. A thin rope groove is provided on the thin rope pulley 11, through which the thin rope is wound through a lower rope tube 25. A rope winding claw 26 is mounted on the thin rope pulley 11 and fixed to the thin rope pulley 11. One end of the rope winding claw 26 faces the thin rope groove, while the distal end faces the end of the rope channel 28, with the distal end of the rope winding claw 26 positioned horizontally. This way, the thick rope drives the rope winding roller 12 to rotate, thereby driving the shaft 27, the thin rope pulley 11, and the rope winding claw 26 to rotate. After the thick rope emerges from the rope channel 28, the thin rope is wound around the thick rope.

[0041] A rope dividing plate 10 is provided below the shaft 27; Figure 5 As shown, the rope splitting plate 10 is provided with a reserved hole, in which an intermediate shaft 30 is mounted. Two bearings 32 are mounted on the intermediate shaft 30. A side gap 29 is reserved between the reserved holes of the two bearings 32, and a middle gap 31 is reserved between the two bearings 32. When in use, a thick rope is passed through the side gap 29, and a thin rope is passed through the middle gap 31.

[0042] A clearance is reserved between the bearing 32 and the inner wall of the reserved hole, so that after the thin rope is wound around the thick rope, it can pass through the clearance as the bearing 32 rotates. At the same time, the width of the rope 35 can be controlled by adjusting the spacing between the two bearings.

[0043] In this way, when working, the thick rope and the thin rope are put into the straw bale, and the straw bale rotates, and the thick rope and the thin rope are rolled into the circumference of the straw bale together. Under the action of the friction between the straw bale and the steel roller, the thick rope and the thin rope are pulled together, and are rotated to the straw bale as the straw bale rotates; when the thick rope and the thin rope are pulled, the rope winding roller 12 is driven to rotate, and the rope winding roller 12 drives the thin rope wheel 11 to rotate, and the rotation of the thin rope wheel 11 drives the rope winding claw 26 to rotate, and the rope winding claw 26 rotates so that the thin rope comes out of the rope winding claw 26 and rotates around the thick rope, thereby interweaving into a mesh rope belt 35, thereby improving the rope winding effect. Figure 7 and Figure 8 shown.

[0044] The above description shows that the rope winding platform 5 reciprocates on the fixed plate 2 driven by the transmission assembly. Next, we will introduce the components of the transmission unit. The transmission unit includes a transmission system and a stop pin 4, which is connected to the transmission system. The stop pin 4 is located within the frame. When the thick rope is pulled, the guide pulley 9 rotates, transmitting power to the transmission system, which in turn drives the transmission system and the stop pin 4. The movement of the stop pin 4 drives the frame, which in turn drives the rope winding platform 5.

[0045] To further ensure the use effect, the frame in this embodiment is rectangular, so that the stop pin 4 contacts the inner wall of one side of the frame, causing the frame to move. When the stop pin 4 moves to the end of the stroke, the stop pin 4 moves up along the frame under the action of the transmission system, and the stop pin 4 pushes the frame to move in the opposite direction, thereby realizing the circular transmission of the stop pin 4 and the reciprocating movement of the rope winding platform 5. As the rope winding platform 5 moves back and forth, the rope is fully wrapped around the straw bale.

[0046] To further ensure the effectiveness of the transmission system, in this embodiment, the transmission system includes a transmission chain 3 and a transmission sprocket, and the stop pin 4 is fixedly connected to a section of the transmission chain 3; the transmission sprocket includes a tensioning wheel, a driving sprocket 8 and a driven sprocket 15, and the guide rope wheel 9 transmits power to the driving sprocket 8.

[0047] The transmission chain 3 is circulated and transmitted between the driving sprocket 8 and the driven sprocket 15; the tensioning wheel is located between the transmission sprockets.

[0048] The tensioning pulleys include an upper tensioning pulley 6 and a lower tensioning pulley 7 that are spaced apart. The upper tensioning pulley 6 is engaged with the conveying chain 3 and is located above the conveying chain 3. The lower tensioning pulley 7 is engaged with the conveying sprocket and is located below the conveying chain 3. The provision of the upper tensioning pulley 6 and the lower tensioning pulley 7 ensures the stability of the conveying chain 3 during the conveying process.

[0049] In order to improve the effect of the guide pulley 9 transmitting power to the driving sprocket 8, a worm 18 is connected to the guide pulley 9, a worm wheel 19 is connected to the worm 18, and a speed transmission mechanism is connected to the worm wheel 19. Figure 3 As shown, the speed change transmission mechanism includes a first non-circular gear, a second non-circular gear, a large cylindrical gear 34, and a small cylindrical gear 33. The worm gear 19 is drivingly connected to the first non-circular gear 16, and the second non-circular gear 17 is meshed with the first non-circular gear 16. The second non-circular gear 17 rotates coaxially with the large cylindrical gear 34, which meshes with the small cylindrical gear 33, and the small cylindrical gear 33 is drivingly connected to the driving sprocket 8. In this embodiment, the size of the large and small cylindrical gears is merely relative and does not represent specific dimensions. The large size of the large cylindrical gear simply means that its size is larger than that of the small cylindrical gear.

[0050] In this embodiment, the first non-circular gear 16 and the second non-circular gear 17 are provided to drive the driving sprocket 8. The variable transmission ratio of the non-circular gears during the transmission process can change the distribution density of the ropes on the bale, thereby achieving a dense-sparse-dense-sparse-dense-sparse-dense effect. Figure 6 As shown, the rope winding effect is improved.

[0051] Example 2: This example differs from Example 1 in that a guide rail 22 is provided on the fixed plate 2 , and a slider 21 is provided on the rope winding platform 5 to cooperate with the guide rail 22 , and the slider 21 moves on the guide rail 22 .

[0052] Example 3. This example differs from Example 1 in that: the fixed plate 2 is arranged vertically, with a mounting gap reserved between the fixed plate 2 and the frame 1. The first non-circular gear 16 and the second non-circular gear 17 are mounted within the mounting gap. The guide wheel is rotatably connected to the rear of the frame 1, and the worm 18 and worm gear 19 are also mounted to the rear of the frame 1. The worm gear 19 transmits power to the first non-circular gear 16 via the first power shaft. The first non-circular gear 16 and the second non-circular gear 17 mesh with each other. The second non-circular gear 17 transmits power to the driving sprocket 8 via the first-stage acceleration gear set, thereby rotating the driving sprocket 8.

[0053] The working process is as follows: the rope reels for thick rope and thin rope are rotatably installed at the rear of the frame 1, wherein the thick rope has two rope reels. After the two thick ropes come out of the rope reels, they bypass the guide rope wheel 9, enter the front of the frame 1, and go around the upper rope tube 24. Through the upper rope tube 24, they enter the rope winding groove 13 of the rope winding roller 12, go along the rope winding groove 13 to the top of the rope winding roller 12, and enter the rope guide tube 23. After coming out of the rope guide tube 23, they enter the rope channel 28. The two thick ropes come out of the rope channel 28 and enter the two side gaps 29 of the rope pressing plate respectively, forming a forked shape.

[0054] After the thin rope is rolled out from the thin rope, it enters the thin rope wheel 11, and after coming out of the thin rope groove, it enters the rope dividing claw. After coming out of the rope dividing claw, it heads towards the rope channel 28. As the thick rope is pulled, it will drive the rope winding roller 12 to rotate, and then the thin rope wheel 11 will also rotate, and finally the rope dividing claw will rotate. When the rope dividing claw rotates, it will be wrapped around the thick rope, and after being wrapped around the thick rope, it will enter the middle gap 31 of the rope dividing plate 10.

[0055] That is, above the rope dividing plate 10, the thin ropes and thick ropes have been wound into a mesh rope belt 35. On the rope dividing plate 10, as the two bearings 32 rotate, the rope belt 35 formed by the mesh thick ropes and thin ropes enters the bottom of the rope dividing plate 10 and is wound around the straw bale.

[0056] As the mesh of thick and thin ropes 35 is wound around the bale, the conveyor chain 3 drives the rope winding platform 5 to move horizontally, allowing the mesh of thick and thin ropes 35 to be wound from one end of the bale to the other. During use, the rope winding platform 5 moves from left to right in the first stroke and from right to left in the second stroke, with the two strokes forming a complete baling process. This allows for repeated winding at both ends during intermittent stages. In addition, due to the use of the first non-circular gear 16 and the second non-circular gear 17, the mesh of thick and thin ropes 35 can be wound with varying densities, resulting in a better winding effect.

[0057] The present invention discloses a rope winding device for straw baling. The movement of the rope winding platform 5 can wind a rope belt 35 made of thick ropes and thin ropes around the straw bale, thereby realizing the rope winding of the straw bale. The device is easy to use and can achieve a good rope winding effect. The wound ropes are sparse and dense on the straw bale. At the same time, when the rope winding platform 5 reaches the end of its travel, due to the action of the transmission chain 3 and the stop pin 4, a period of time is left, thereby achieving a dense rope winding effect at the end of the straw bale and avoiding looseness.
