Technical Field
[0001] This utility model relates to the field of agricultural seedling pulling technology, and in particular to an adjustable clamping and conveying device for seedling pulling. Background Technology
[0002] The clamping and conveying structure is a core component of agricultural transplanting machinery. It is specifically designed to pull out seedlings and stably transport them to subsequent transplanting and seedling separation stations through clamping. Its core objective is to achieve efficient seedling pulling.
[0003] However, existing clamping and conveying structures have fixed clamping parameters, making it difficult to match diverse needs. They cannot adjust the clamping force in real time, which can easily lead to problems with seedling carrying. At the same time, the guide components are mostly in a fixed orientation, and their conveying orientation cannot be adjusted according to usage requirements.
[0004] Therefore, an adjustable clamping and conveying device for pulling seedlings is needed to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of poor adjustment capability. To address this, we propose an adjustable clamping and conveying device for pulling seedlings.
[0006] To achieve the above objectives, this application adopts the following technical solution: an adjustable clamping and conveying device for seedling pulling, comprising a connecting platform, on one side of the connecting platform, a first gear and a second gear are movably connected to the upper end of the connecting platform, and a motor is fixedly connected thereto. The output end of the motor is fixedly connected to the first gear, and the surface of the first gear meshes with the second gear. The bottom ends of the first gear and the second gear are both fixedly connected to driving rollers, and the driving rollers are movably connected to the bottom end of the connecting platform. A belt is movably connected to the outer surface of the connecting platform, and a driven roller is movably connected to the inner side of one end of the belt. Adjustment components are evenly distributed on the inner side of the belt. The motor drives the first gear to rotate, so that the driving rollers at the bottom ends of the first gear and the second gear cooperate with the driven rollers to drive the belt to convey the seedlings. The inner adjustment components adjust the clamping width according to the thickness of the seedlings to adapt to seedlings of different sizes.
[0007] Preferably, the adjusting component includes a crossbar assembly, a first fixed post is fixedly connected to the top of the crossbar assembly, a partition post is fixedly connected to the top of the first fixed post, a second fixed post is fixedly connected to the top of the partition post, a limit cap is fixedly connected to the upper surface of the second fixed post, and movable rings are symmetrically distributed and rotatably connected to the surfaces of the first fixed post and the second fixed post.
[0008] Preferably, the surfaces of the two sets of movable rings are provided with torsion springs, the torsion springs are sleeved on the surfaces of the first fixed post and the second fixed post, and one end of the torsion spring is inserted into the interior of the first fixed post and the second fixed post. The other end of the torsion spring is inserted into the interior of the movable ring. An extension rod is fixedly connected to one side of the two sets of movable rings, and a pulley is movably connected between the two sets of extension rods.
[0009] Preferably, the crossbar assembly includes a crossbar body, which is fixedly connected to the bottom end of the first fixed post. One end of the crossbar body is provided with an upper boss, and the surface of the upper boss is provided with a first threaded hole. The other end of the crossbar body is provided with a lower boss, and the surface of the lower boss is provided with a second threaded hole, the diameter of which is larger than the diameter of the lower boss.
[0010] Preferably, the surface of the crossbar assembly is threaded with a threaded post, the diameter of which is adapted to the first threaded hole, and the bottom end of the threaded post is threaded with a screw bolt. A set of second threaded holes away from the motor is movably connected with a threaded rod, which is movably connected to the bottom end of the driven roller.
[0011] Preferably, a set of pulleys near the bottom of the crossbar assembly is threaded with a connecting seat, and an L-shaped lever is fixedly connected to the surface of the connecting seat.
[0012] The technical effects and advantages of this utility model are as follows: 1. In this utility model, the connecting platform and the seedling puller are fixed by bolts. The motor drives the gear set to rotate, causing the active roller at the bottom of the connecting platform to rotate, which in turn drives multiple sets of belts to transport seedlings in conjunction with the driven roller. The inner side of the belt is connected to the first fixed column and the second fixed column via a separator column. The first fixed column has a movable ring, and the pulley connected to the extension rod fits against the inner side of the belt. When the seedlings come into contact with the belt, they push the pulleys outward, and the movable ring rotates to compress the torsion spring. When the seedlings move away, the springs spring back to their original position. The upper and lower sets of pulleys are adapted to seedlings of different sizes and diameters, ensuring stable clamping. At the same time, the crossbar assembly can be loosened by turning the horn bolts, and the conveying direction can be adjusted by rotation.
[0013] 2. In this utility model, a threaded hole is provided at the bottom end of the connecting shaft of the lower pulley, and the connecting seat is connected to the connecting shaft of the lower pulley, so that the L-shaped lever is fixed at the bottom end of the device. When the lower pulley is rotated by the belt, the bottom L-shaped lever rotates with the pulley, and then the bottom end of the seedling is moved by the rotation. The two sets of L-shaped levers cooperate with each other to shake off the soil on the surface of the root system. Attached Figure Description

A second fixing post 21 is fixedly connected to the top of the separator post 10, and the second fixing post 21 has the same function as the first fixing post 9. A limit cap 11 is fixedly connected to the upper surface of the second fixing post 21, which limits the upper movable ring 12. The first fixing post 9 and the second fixing post 21... The surface of the belt 6 is symmetrically distributed and rotatably connected with movable rings 12. The surfaces of the two sets of movable rings 12 are provided with torsion springs 15. The torsion springs 15 are used to adjust the distance between the two pulleys 14 and reset them. The torsion springs 15 are sleeved on the surfaces of the first fixed post 9 and the second fixed post 21, with one end inserted into the interior of the first fixed post 9 and the second fixed post 21. The other end of the torsion springs 15 is inserted into the interior of the movable rings 12. One side of the two sets of movable rings 12 is fixedly connected with an extension rod 13. The extension rod 13 is used to connect the pulleys 14. The two sets of extension rods 13 are movably connected with pulleys 14. The pulleys 14 are used to keep the belt 6 running smoothly.
[0019] The crossbar assembly 7 includes a crossbar body 705, which serves as the main connecting and supporting structure. The crossbar body 705 is fixedly connected to the bottom end of the first fixed column 9. One end of the crossbar body 705 is provided with an upper boss 701, and the bottom end of the upper boss 701 is provided with a groove that matches the lower boss 703, for keeping multiple sets of crossbar bodies 705 at the same level. The surface of the upper boss 701 is provided with a first threaded hole 702, which is used to connect with other crossbar assemblies 7. A set of first threaded holes 702 near the connecting platform 1 is fixed to the seedling puller by bolts. The other end of the crossbar body 705 is provided with a lower boss 703. The surface of the lower boss 703 is provided with a second threaded hole 704, which is used to connect with the first threaded hole 702. The diameter of the second threaded hole 704 is larger than the diameter of the lower boss 703. The surface of the crossbar assembly 7 is threaded with a threaded post 16, which is used to cooperate with the horn bolt 17 to clamp and connect the two sets of crossbar assemblies 7. The diameter of the threaded post 16 is adapted to the first threaded hole 702. The bottom end of the threaded post 16 is threaded with a horn bolt 17. The surface of the second threaded hole 704 away from the motor 2 is movably connected with a threaded rod 18, which is used to support the driven roller 8. The threaded rod 18 is movably connected to the bottom end of the driven roller 8.
[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in this embodiment: the connecting platform 1 is fixed to the seedling puller with bolts. During use, the motor 2 on the surface of the connecting platform 1 drives the first gear 4 and the second gear 5 meshing with the surface of the first gear 4 to rotate, causing the two sets of driving rollers 3 at the bottom of the connecting platform 1 to rotate. The driving rollers 3 and the driven rollers 8 cooperate to make multiple sets of belts 6 rotate. The belts 6 clamp the seedlings and transport them to the rear end. The inner side of the belts 6 is connected to the first fixed post 9 and the second fixed post 21 through the partition post 10. The movable ring 12 is set on the surface of the first fixed post 9 and the second fixed post 21. The extension rod 13 connected to the movable ring 12 is attached to the inner side of the belt 6 through the pulley 14. When the seedlings come into contact with the pulley 14, the diameter of the seedlings pushes the pulley 14 to expand outward, thereby causing the movable ring 12 to rotate. At this time, the torsion spring 15 is compressed by the torsional force. When the seedlings move away from the pulley, the torsion spring 15 is compressed. At 14 o'clock, the torsion spring 15 rebounds, causing the pulley 14 to reset, and the belts 6 to come into contact with each other, so that it can adapt to seedlings of different sizes, while avoiding seedlings with different overall diameters. The upper and lower sets of pulleys 14 clamp the seedlings at different heights to ensure their stability. When it is necessary to adjust the conveying direction, the two sets of crossbar assemblies 7 are loosened by turning the horn bolt 17 at the bottom of the threaded column 16, and the direction can be adjusted by rotating the angle. It should be noted that in this structure, the diameter of the second threaded hole 704 is larger than that of the first threaded hole 702 (refer to the attached diagram of the instruction manual, the active roller 3). The threaded column 16 is only threadedly connected to the first threaded hole 702 and the horn bolt 17. Its connection capacity mainly comes from the clamping force of the horn bolt 17 and the threaded column 16. The design of this structure is mainly to avoid the situation where the second threaded hole 704 cannot rotate.
[0021] Reference Figure 5 As shown, this utility model provides a technical solution: an adjustable clamping and conveying device for seedling pulling, comprising: a set of pulleys 14 near the crossbar assembly 7 with a connecting seat 20 threaded to the bottom end, the connecting seat 20 being used to connect an L-shaped lever 19, the surface of the adjusting connecting seat 20 being fixedly connected to an L-shaped lever 19, the L-shaped lever 19 being used to shake off the soil at the bottom of the seedling.
[0022] Reference Figure 5 As shown in this embodiment, further: a threaded hole is provided at the bottom of the connecting shaft of the lower pulley 14, and the connecting seat 20 is connected to the connecting shaft of the lower pulley 14, so that the L-shaped lever 19 is fixed at the bottom of the device. When the lower pulley 14 is rotated by the belt 6, the bottom L-shaped lever 19 rotates with the pulley 14, and then the bottom of the seedling is moved by the rotation. The two sets of L-shaped levers 19 cooperate with each other to shake off the soil on the surface of the root system.
[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
