Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a swingable synchronizer for seedling picking claws. Background Technology
[0002] Agricultural machinery plays a crucial role in modern agricultural production. Through mechanized operations, it significantly improves agricultural production efficiency, enabling humans to complete various complex agricultural production tasks in a shorter time. This not only reduces the labor intensity of farmers but also makes agricultural production more intensive and large-scale. The use of agricultural machinery also helps reduce agricultural production costs and improve the market competitiveness of agricultural products. With the continuous development of science and technology, the performance and intelligence level of agricultural machinery are also constantly improving, providing strong support for the sustainable development of agricultural production.
[0003] The swinging synchronizer of the seedling grabbing claw plays a crucial role in automated transplanting operations. It ensures that the grabbing claw performs precise and synchronized swinging movements when grasping seedlings, thereby effectively guaranteeing the stability and consistency of each seedling during the transplanting process. It achieves precise coordination between the grabbing claw and other components of the transplanting machinery, avoiding seedling damage or poor transplanting results caused by asynchronous operation. At the same time, the swinging synchronizer of the seedling grabbing claw also has good adaptability and flexibility. It can adjust the swing amplitude and frequency according to the different growth characteristics of seedlings and transplanting needs, achieving efficient and precise transplanting operations, which greatly improves agricultural production efficiency and seedling survival rate.
[0004] Traditional seedling pickers are typically complex to operate, requiring operators to possess certain skills and experience. Otherwise, it is difficult to achieve precise and efficient transplanting operations. During the process of picking up and releasing seedlings, the complex linkage between various components may make it difficult for the picker to pick up and release seedlings, resulting in some seedling trays having multiple seedlings or even no seedlings. At the same time, it may damage the seedlings, such as crushing the pot or breaking the stem, thereby affecting the transplanting effect and survival rate of the seedlings. Therefore, a swingable synchronizer for the seedling picker is proposed. Utility Model Content

[0028] Example 1
[0029] like Figures 1-6 As shown, the present invention proposes a swaying synchronizer for seedling pickers, comprising a guide plate 1, a seedling rack drive shaft 6, and a drive shaft 9. The seedling rack drive shaft 6 and the drive shaft 9 are fixedly connected to the guide plate 1. A guide pin groove 8 is provided at the top of the guide plate 1, and the guide pin groove 8 completely penetrates the guide plate 1. A first linkage guide groove 7 and a second linkage guide groove 28 are respectively provided at the top of the guide plate 1, and both the first linkage guide groove 7 and the second linkage guide groove 28 penetrate the guide plate 1. Sliding seedling picker frames 14 are symmetrically slidably connected to the bottom of the guide plate 1. A sliding seat frame 15 is fixedly connected between the two sliding seedling picker frames 14, and a flipping seat is rotatably connected between them. The frame 16, the sliding frame 15, and the flipping frame 16 are all equipped with a seedling taking component. The seedling taking component includes an arc-shaped plate 19 installed on the guide plate 1, a flipping plate 26 and a seedling claw 22 installed on the arc-shaped plate 19, a reciprocating flipping groove 25 provided on the flipping plate 26, a first sliding seat 20 installed on the sliding frame 15, and a second sliding seat 21 installed on the flipping frame 16. The seedling taking component drives the flipping frame 16 to flip through the drive shaft 9. The flipping frame 16 guides the seedling claw 22 to slide along the reciprocating flipping groove 25. The seedling frame drive shaft 6 drives the first sliding seat 20 and the second sliding seat 21 to slide along the sliding frame 15 and the flipping frame 16, respectively.
[0030] A first transmission assembly is provided on the drive shaft 9 and the flipping seat 16. The first transmission assembly includes a flipping crank 10, a flipping connecting rod 11, and a rocking arm 12. A second transmission assembly is provided on the seedling frame drive shaft 6 and the sliding seat 15. The second transmission assembly includes a reciprocating crank 5, a transmission connecting rod 3, and a driven rod head 4.
[0031] The output end of the seedling frame drive shaft 6 is fixedly connected to the reciprocating crank 5, the reciprocating crank 5 is rotatably connected to the transmission connecting rod 3, and the transmission connecting rod 3 is rotatably connected to the driven rod head 4.
[0032] The drive shaft 9 and the flip crank 10 are fixedly connected, and the flip crank 10 and the flip connecting rod 11 are rotatably connected. The outer side of the flip connecting rod 11 is provided with a connecting rod elongated hole 18, and the inner side of the connecting rod elongated hole 18 is slidably provided with a swing arm hinge pin 17.
[0033] The swing arm hinge pin 17 is fixedly connected to the rocking swing arm 12. The inner side of the rocking swing arm 12 is rotatably connected to the seat frame shaft 13. The seat frame shaft 13 is fixedly connected to the flipping seat frame 16. The seat frame shaft 13 is rotatably connected to the sliding seedling claw frame 14. The bottom of the guide plate 1 is symmetrically provided with sliding grooves 27, and the sliding grooves 27 are slidably connected to the sliding seedling claw frame 14.
[0034] In this embodiment, during actual operation, the rotation of the seedling frame drive shaft 6 drives the reciprocating crank 5 to rotate. At the same time, the guide pin groove 8 provides guidance, driving the driven rod head 4 to reciprocate along the guide pin groove 8. The reciprocating motion of the driven rod head 4 drives the reciprocating motion of the sliding seat 15. The reciprocating motion of the sliding seat 15 drives the first sliding seat 20, which is slidably connected to it, to reciprocate. At the same time, the first linkage guide groove 7 guides the rotating bearing 2, allowing the rotating bearing 2 to move along the first linkage guide groove 7. Simultaneously, the movement of the rotating bearing 2 drives the movement of the bow plate 19. The movement of the bow plate 19 drives the first sliding seat 20 to slide on the sliding seat 15. When the sliding seat 15 slides to and approaches the matching seedling delivery device, the rotation of the second drive motor 9 is then controlled to drive the rotation of the flip crank 10. The rotation of the flip crank 10 drives the movement of the flip connecting rod 11.
[0035] The connecting rod elongated hole 18 on the flipping connecting rod 11 limits and guides the swing arm hinge pin 17, causing the swing arm hinge pin 17 to flip. The flipping of the swing arm hinge pin 17 causes the seat frame rotating shaft 13 to rotate. The rotation of the seat frame rotating shaft 13 causes the flipping seat frame 16, which is fixedly connected to it, to flip. The flipping of the flipping seat frame 16 causes the second slide block 21, which is slidably set to it, to flip. The flipping of the second slide block 21 causes the seedling claw 22 to flip. During the flipping process of 22, the seedling claw will move along the guide of the reciprocating flipping groove 25. Then, the control of the matching pneumatic equipment controls the seedling claw 22 to clamp the seedling and pick up the seedling. In this way, the seedling is picked up. The first drive component and the second drive component can work together to achieve precise positioning of the seedling by precisely controlling the movement trajectory and speed of the seedling picking component. This cooperation ensures that the seedling is picked up accurately every time, avoiding the situation of too many seedlings, too few seedlings, or no seedlings due to improper operation.
[0036] Example 2
[0037] like Figures 1-6 As shown, based on Embodiment 1, the driven rod head 4 is fixedly connected to the sliding seat 15, and the driven rod head 4 is slidably connected to the guide pin groove 8.
[0038] Rotary bearings 2 are slidably provided on the inner side of both driven rod heads 4. The first linkage guide groove 7 and the second linkage guide groove 28 are slidably connected to the rotary bearings 2. The rotary bearings 2 are fixedly connected to the bow plate 19. The first slide 20 is fixedly connected to the side of the bow plate 19 near the seedling claw 22. The first slide 20 is slidably connected to the sliding seat frame 15.
[0039] The side of the bow-shaped plate 19 away from the first slide block 20 is fixedly connected to the flip plate 26. The side of the flip plate 26 is provided with a reciprocating flip groove 25, which completely penetrates the flip plate 26. A sliding column 24 is slidably connected to the inner side of the reciprocating flip groove 25, and a fixing plate 23 is fixedly connected to the outer side of the sliding column 24.
[0040] The second slide 21 is fixedly connected to the side of the fixed plate 23 away from the side closest to the second slide 21. The second slide 21 is slidably connected to the flipping frame 16. The fixed plate 23 is fixedly connected to the seedling claw 22.
[0041] In this embodiment, after the curved surface is completed, the seedling frame drive shaft 6 drives the driven rod head 4 to move in the opposite direction. Similar to the above process, the movement of the driven rod head 4 drives the movement of the sliding seat 15. At the same time, the first linkage guide groove 7 guides the driven rod head 4 to slide the seedling 22 in the direction of the sliding seat 15, while having the same movement trajectory as the first linkage guide groove 7. Then, the drive shaft 9 drives the flipping seat 16 to flip again. The flipping seat 16 drives the seedling claw 22 to flip. During the flipping process, the seedling claw 22 moves along the guide of the reciprocating flipping groove 25. At this time, the seedling claw 22 is in a horizontal state. Then, the matching pneumatic equipment is controlled to control the seedling claw 22 to put the seedling. Repeating the above process completes a precise seedling picking and putting process. In the above process, the linkage effect between the various structures greatly reduces the steps and time of manual operation in the seedling picking process, thereby significantly improving work efficiency. Through the cooperation of the first drive component, the second drive component, and the seedling picking component, the seedling picking cycle can be further shortened and the overall operation speed can be improved.
