Description

Technical Field

[0001] The utility model relates to a straw row returning device, in particular to an adaptive straw row returning device, belonging to the technical field of protective tillage. Background Art

[0002] In the prior art, the utility model with application number 201721460718.4 discloses a front-mounted corn protective tillage straw return machine. In order to solve the problem that there is a large amount of residual straw in the seedbed before sowing, sowing at this time seriously affects the emergence rate, and the autumn return operation is not conducive to moisture conservation in the seedling belt during spring sowing, the machine is raised as a whole through the oil cylinder during transportation and at the end of the field to ensure ground clearance. During operation, the machine is lowered to the ground through the oil cylinder so that the spring teeth are in contact with the ground surface. When the tractor is running, the spring teeth generate friction with the ground, and its lateral force causes the finger plate to rotate. The rotating finger plate distributes the straw to both sides of the seedling belt, so that the seedling belt is clean and the sowing efficiency is ensured.

[0003] Similar to the above application, there are still some deficiencies:

[0004] During operation, the oil cylinder can be used to control the descent of the two sets of grass-pulling wheels, and the return spring can be used to make the bottom surfaces of the grass-pulling wheels fit together. However, when working inside the ridge, the bottom surface has a slope, and the two sets of grass-pulling wheels can only operate on the horizontal surface. They cannot adapt to the inclined terrain of the ridge, and their practicality is low.

[0005] Therefore, an adaptive straw returning device is designed to optimize the above problems. Utility Model Content

During use, the mounting frame can rotate with the line connecting the first ball and the second ball as the axis, fit against the ground, adapt to different terrains, and have higher practicality. By arranging a positioning assembly composed of a storage box, a cover, a spool, a pull rope, and a hook at both ends of the top of the mounting frame, the grass-plowing wheel can be limited when not in use, avoiding damage to passers-by caused by the rotation of the grass-plowing wheel when the dragging device is moving, thereby improving safety in use.

However, the embodiments of the present utility model are not limited thereto.

[0024] As Figures 1-4 shown, this embodiment provides an adaptive straw alignment device, including a main support 1, a mounting frame 7 located at the bottom side of the main support 1, and grass-pulling wheels 8 rotatably installed at both ends of the mounting frame 7. A first rotating shaft 2 is rotatably installed at the top of the inner side of the main support 1. Cantilevers 3 are symmetrically installed at both ends of the first rotating shaft 2. A second rotating shaft 4 is rotatably installed at the middle position between the two groups of cantilevers 3. A third rotating shaft c5 is rotatably installed between the ends of the two groups of cantilevers 3. An oil cylinder 6 is hingedly installed on the inner side of the main support 1. The output end of the oil cylinder 6 is connected to the second rotating shaft 4. A shock absorber 11 is installed on the third rotating shaft 5. A spring 12 is sleeved outside the shock absorber 11. A second rotating connector 10 is provided between the bottom end of the shock absorber 11 and the mounting frame 7. A first rotating connector 9 is provided between the end of the mounting frame 7 and the main support 1. Positioning assemblies 18 for limiting the grass-pulling wheels 8 are provided at both ends of the top of the mounting frame 7.

[0025] Overall working principle: During use, the main support 1 is installed on the tractor. During the use process, the hydraulic system of the tractor controls the telescoping of the oil cylinder 6, controls the lifting and release of the mounting frame 7. During the use process, the weeding wheels 8 at both ends of the mounting frame 7 are in contact with the ground. Due to the arrangement of the first rotating connector 9 and the second rotating connector 10, the mounting frame 7 is in an actively connected state and can be adjusted in angle. The weeding wheels 8 on the mounting frame 7 can work on an inclined or horizontal plane. During the use process, by the extrusion of the elastic force of the spring 12, the inclination of the mounting frame 7 is controlled to adapt to different terrains for use.

[0026] In this embodiment, the first rotating connector 9 includes a first mounting block 13, a first ball bead 14 and a connecting rod 15. The first mounting block 13 is fixed at the bottom inside the main support 1. The first ball bead 14 is rotatably installed inside the first mounting block 13. A connecting rod 15 is fixed between the first ball bead 14 and the end of the mounting frame 7.

[0027] Local working principle: The first ball bead 14 can rotate inside the first mounting block 13. Therefore, the mounting frame 17 can perform multi-angle rotational swinging with the first ball bead 14 as the fulcrum.

[0028] In this embodiment, the second rotating connector 10 includes a second mounting block 16 and a second ball bead 17. The second mounting block 16 is fixed at the top of the mounting frame 7. The second ball bead 17 is rotatably installed at the top of the second mounting block 16. The bottom end of the shock absorber 11 is fixedly connected to the surface of the second ball bead 17.

[0029] Local working principle: The front end and the top of the mounting frame 7 are in an actively connected state. Due to the limiting effect of the first ball bead 14 and the second ball bead 17, the mounting frame 7 can perform rotational swinging with the connection line of the first ball bead 14 and the second ball bead 17 as the axis to ensure the stability of the support and adapt to different terrains at the same time.

[0030] In this embodiment, rubber protective covers are provided on the outer sides of the first ball bead 14 and the second ball bead 17, and the rubber protective covers wrap the first ball bead 14 and the second ball bead 17.

[0031] Local working principle: By using the rubber cover, it can prevent soil from affecting the rotation of the ball beads and ensure the stable use of the device.

[0032] In this embodiment, the positioning component 18 includes a storage box 19, a cover plate 20, a spool 21, a pull rope 22 and a hook 23. The storage box 19 is fixed at the top of the mounting frame 7. The cover plate 20 is hingedly installed at the top of the storage box 19. A spool 21 is rotatably installed between the two ends of the storage box 19. A pull rope 22 is wound around the outer side of the spool 21. A hook 23 is fixed at the end of the pull rope 22.

[0033] Local working principle: After use, open the cover plate 20, pull out the internal drawstring 22 and hang the hook 23 on the weeding wheel 8 to position the weeding wheel 8 and prevent the weeding wheel 8 from rotating when the dragging device moves.

[0034] In this embodiment, buckle grooves are provided at the top of the cover plate 20, and a sealing gasket is provided at the bottom of the cover plate 20.

[0035] Local working principle: The use of the buckle groove facilitates the opening of the cover plate 20, making it convenient to use.

[0036] In this embodiment, anti-slip patterns are evenly provided along the circumferential direction at both ends of the spool 21, and the anti-slip patterns are parallel to the length direction of the spool 21.

[0037] Local working principle: When winding the drawstring 22, manually control the rotation of the spool 21 to wind and wrap the drawstring 22. The use of the anti-slip patterns makes the rotation of the spool 21 more convenient.

[0038] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
