[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: an agricultural machinery traction device, including a plurality of fixed piles 1 for fixing a steel rope 7. The inner wall of the top of the fixed pile 1 is fixedly connected with a sleeve 2. The sleeve 2 cooperates with a lifting column 6 to form a locking structure to fix the steel rope 7. On the left and right inner walls of the bottom of the fixed pile 1, two first chutes 3 are respectively opened. The inner wall of the first chute 3 is slidably connected with a limiting block 4. The sliding of the limiting block 4 in the first chute 3 enables the lifting plate 5 to lift, so as to drive the lifting column 6 to move vertically. The top of the two limiting blocks 4 is fixedly connected with a lifting plate 5. The top of the lifting plate 5 is fixedly connected with a lifting column 6, which forms a locking structure with the sleeve 2. The bottom of the lifting plate 5 is fixedly connected with two connecting shafts 8. The bottom end of the connecting shaft 8 is rotatably connected with a rotating rod 9. By the cooperation of the rotating rod 9 and the connecting shaft 8, the sliding column 10 slides in the second chute 12 to form a self-locking structure. The outer wall of the other end of the rotating rod 9 is fixedly connected with a sliding column 10. The inner wall of the bottom of the fixed pile 1 is fixedly connected with a fixed block 11. The chute on the fixed block 11 has a special structure to form a locking structure when the sliding column 10 slides. Two second chutes 12 are respectively opened on the left and right sides of the fixed block 11 to provide a sliding track for the sliding column 10. The outer wall of the bottom of the lifting plate 5 is fixedly connected with a limiting column 13 to prevent the first spring 14 from shifting when deforming. The outside of the limiting column 13 is sleeved with a first spring 14. The deformation recovery of the first spring 14 drives the lifting plate 5 to reset. The outer wall of the fixed pile 1 is fixedly connected with a detachable component for fixing the traction device on the traction vehicle head and the agricultural machinery.

[0032] Referring to Figure 1 , Figure 2 , Figure 4, the detachable component includes a connecting plate 15 and a second connecting column 18. The connecting plate 15 is used to connect the traction device and the detachable component, and the second connecting column 18 is used to connect the tractor and the agricultural machinery. A first connecting column 16 is fixedly connected to the outer wall of the connecting plate 15. The agricultural machinery is connected to the tractor through the connection between the first connecting column 16 and the second connecting column 18. A plurality of groove columns 17 are fixedly connected to the other side of the first connecting column 16. The groove columns 17 cooperate with the clamping columns 20 to form a locking structure to fix the traction device on the agricultural machinery and the tractor. A plurality of inner boxes 19 are fixedly connected to the inside of the second connecting column 18. The inner boxes 19 are used to protect the internal self-locking structure. A clamping column 20 is slidably connected to the inside of the inner box 19. When the clamping column 20 moves, it engages with the grooves on the groove columns 17 to form a locking structure. A limiting plate 21 is fixedly connected to the outer wall of the clamping column 20. The limiting plate 21 is used to limit the deformation of the second spring 22. A second spring 22 is fixedly connected to the top of the limiting plate 21. An inclined column shell 23 is fixedly connected to the top of the inner box 19. The clamping column 20 can be disassembled through the closing and separation of the inclined column shell 23 and the bottom of the button 24, so as to facilitate the separation of the agricultural machinery and the tractor. A button 24 is fixedly connected to the top of the clamping column 20.

[0033] Refer to Figures 2 - 4 , a steel rope 7 is sleeved outside the lifting column 6. The steel rope 7 is used to connect the two fixed piles 1, so that the movement of the tractor drives the movement of the agricultural machinery. The outer wall of the sliding column 10 slides on the inner wall of the second chute 12. A self-locking structure is formed through the sliding of the sliding column 10 in the second chute 12. One end of the first spring 14 is fixedly connected to the top of the lifting plate 5, and the other end of the first spring 14 is fixedly connected to the bottom of the fixed pile 1. The lifting column 6 is locked and unlocked by the deformation and recovery of the spring. The outer wall of the connecting plate 15 is fixedly connected to the outer wall of the fixed pile 1. The bottom outer wall of the clamping column 20 slides on the bottom inner wall of the groove column 17, so that the clamping column 20 can engage with the groove column 17 to connect the first connecting column 16 and the second connecting column 18. The bottom outer wall of the button 24 is in contact with the top outer wall of the inclined column shell 23, so that the bottom of the button 24 can rotate on the top of the inclined column shell 23 to prevent the automatic engagement and locking of the clamping column 20 and the groove column 17 from causing inconvenience when replacing the agricultural machinery. The outer wall of the limiting plate 21 is in contact with the inner wall of the inner box 19 to make the sliding of the clamping column 20 stable. The inner wall of the second connecting column 18 is in contact with the outer wall of the first connecting column 16. The other end of the second spring 22 is fixedly connected to the top inner wall of the inner box 19. When the second spring 22 resumes deformation, it drives the automatic engagement of the clamping column 20 and the groove column 17. The outer wall of the clamping column 20 is in contact with the inner wall of the inclined column shell 23, so that the clamping column 20 can rotate and slide inside the inclined column shell 23.

[0034] Working principle: By pulling and rotating the button 24, the clamping post 20 is driven to move outwards. Together with the limiting plate 21, the clamping post 20 compresses the second spring 22, separating the clamping post 20 from the groove post 17. At the same time, the bottom end of the button 24 abuts against the top of the inclined post housing 23, restricting the second spring 22 from restoring deformation, thereby separating the agricultural machinery from the tractor for equipment replacement. Rotating the button 24 again, the bottom end of the button 24 fits with the top of the inclined post housing 23, and the second spring 22 restores deformation to drive the limiting plate 21 to move, thereby driving the clamping post 20 to move inwards to engage with the groove post 17, fixing the agricultural machinery and the tractor. Then, by pressing the lifting plate 5, the lifting plate 5 moves, causing the limiting block 4 to slide in the first chute 3. At the same time, the first spring 14 is compressed. The descending of the lifting plate 5 drives the rotating rod 9 to descend, causing the sliding post 10 to slide in the second chute 12 along the corresponding track, driving the rotating rod 9 to rotate. When the sliding post 10 moves to the bottom of the second chute 12, a self-locking structure is formed. At this time, the lifting column 6 is separated from the sleeve 2, and the steel rope 7 can be sleeved. After the steel rope 7 is sleeved, pressing the lifting plate 5 again drives the sliding post 10 to slide to the top of the second chute 12. At this time, the self-locking structure is opened, and the first spring 14 restores deformation to drive the lifting plate 5 to move upwards, driving the lifting column 6 to move upwards into the sleeve 2 to form a fixed structure, and the sleeve 2 bears the tension received by the lifting column 6, thereby fixing the steel rope 7 in the traction device and connecting the tractor and the agricultural machinery.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
