Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, specifically to an automatic uprighting structure for melon seedling cuttings. Background Technology

[0002] Cucurbit crops (such as watermelon, cantaloupe, cucumber, and pumpkin) are widely cultivated economic crops globally, with a large-scale industry and stable market demand, occupying an important position in agricultural production. Seedling cultivation is a key step in cucurbit crop cultivation, and cutting propagation, as one of the core technologies for cucurbit seedling reproduction, directly affects the survival rate, growth uniformity, and subsequent field yield of seedlings.

[0003] Traditional methods of seedling propagation cannot control the posture of seedlings during the extraction process, resulting in a low success rate. Furthermore, the lack of compaction of the substrate after propagation further compromises the survival rate of the seedlings. Additionally, most cucurbit seedling propagation operations rely heavily on manual labor, requiring significant manpower and exhibiting extremely low efficiency. Therefore, those skilled in the art have developed an automatic uprighting structure for cucurbit seedling propagation to address the problems mentioned in the background section.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This automatic seedling straightening and cutting structure for cucurbits integrates automatic seedling straightening and precise cutting by using a servo motor-driven gripper and straightening frame. This eliminates the need for manual posture adjustment, significantly improving work efficiency and reducing labor costs for large-scale seedling cultivation. The linkage control between the straightening and cutting frames prevents posture deviation during seedling transfer. Adjustable grippers and rods adapt to different cucurbit varieties and seedlings at different growth stages, greatly increasing the verticality of the cutting posture, ensuring even root distribution, significantly improving survival rate, and enhancing growth consistency. Hydraulic cylinders and servo motors precisely control the cutting depth and position, adapting to various seedling substrates. Furthermore, the equipment can be integrated into intelligent seedling systems, promoting the automation and standardization of cucurbit seedling cultivation and helping growers improve quality and efficiency.

[0021] Please see Figures 1-4 In this embodiment of the present invention, an automatic uprighting seedling cutting propagation structure for melons includes a frame 1, a first servo motor 14, and a second servo motor 15. A longitudinal slide rail 2 and a transverse slide rail 3 are provided on the front of the frame 1. A movable plate 4 is slidably connected to the transverse slide rail 3 via a sliding block. A connecting block 5 is fixedly connected to the movable plate 4. Two adjusting wheels 6 are fixedly connected to one side of the connecting block 5. An adjusting plate 7 is fixedly connected to the outer surface of the connecting block 5. A movable groove 8 is provided on one side of the connecting block 5, and a gripper 9 is slidably connected inside the movable groove 8. An uprighting frame 12 is fixedly connected to the output end of the first servo motor 14. A cutting propagation frame 13 is fixedly connected to the output end of the second servo motor 15. A third servo motor 16 is fixedly installed on one side of the connecting block 5. The output end of the third servo motor 16 is fixedly connected to the gripper 9. The connecting block 5 integrates the gripper 9, adjusting wheels 6, and other components, enabling multi-component coordinated action, reducing connection gaps between components, improving the synchronization of overall action, and ensuring the continuity of seedling clamping and uprighting. The cutting frame 13 is driven by the second servo motor 15 to complete the action of inserting the seedling into the substrate. Its end design can reduce the resistance of the substrate during insertion, ensure uniform cutting depth, and prevent the seedling from falling over.

[0022] A base 10 is fixedly connected to the bottom surface of the frame 1. A first driver 11 is fixedly installed on the upper surface of the base 10. A connecting plate 26 is fixedly connected to the output end of the first driver 11. The left side of the connecting plate 26 is fixedly connected to a first servo motor 14, and the left side of the connecting plate 26 is fixedly connected to a second servo motor 15. A steering rod 25 is fixedly connected to the left side of the connecting plate 26. A guide plate 17 is slidably connected to the outer surface of the frame 1, and two guide wheels 18 are fixedly connected to the outer surface of the frame 1. The first driver 11 provides power for the overall movement of the straightening frame 12 and the cutting frame 13. By precisely controlling the output speed and stroke, the frame 12 can quickly switch between the straightening and cutting positions, improving the work rhythm. The second servo motor 15 drives the cutting frame 13 to complete the lifting action, precisely controlling the cutting depth. The depth can be flexibly set according to the needs of different melon seedlings to meet diverse cutting requirements.

[0023] A fixing block 19 is fixedly connected to the outer surface of the movable plate 4. A movable frame 27 is slidably connected inside the longitudinal slide rail 2. A second driver 20 is fixedly installed on the right side of the movable frame 27. A hydraulic cylinder 21 is fixedly installed on the right side of the frame 1. Two adjusting rods 22 are fixedly installed on one side of the connecting block 5. A round tube 23 is fixedly connected to the outer surface of each of the two adjusting rods 22. A set of positioning screws 24 is threadedly connected to one side of the connecting block 5. A connecting plate 26 is fixedly connected to the output end of the first driver 11. A steering rod 25 is fixedly connected to the left side of the connecting plate 26. One end of the steering rod 25 is fixedly connected to one side of the straightening frame 12. The left side of the connecting plate 26 is fixedly connected to the cutting frame 13. The fixing block 19, in conjunction with the transverse slide rail 3, enables the movable plate 4 to slide with low resistance, improving the response speed and accuracy of transverse adjustment, allowing the gripper 9 to quickly align with the seedling position. The round tube 23 connects the two adjusting rods 22, ensuring that the adjusting force is evenly transmitted, ensuring synchronous adjustment on both sides, avoiding seedling clamping deviation due to uneven force, and ensuring the accuracy of posture correction.

[0024] The working principle of this utility model is as follows: First, after the equipment is started, it is supported by the frame 1, and the base 10 ensures overall stability. First, the transverse slide rail 3 drives the moving plate 4 to move laterally through the sliding block. The connecting block 5 connected to the moving plate 4 adjusts its position accordingly. At the same time, the second driver 20 on the moving frame 27 drives the fixing block 19 to assist in fine adjustment, so that the gripper 9 is aligned with the seedling to be picked. Then, the third servo motor 16 starts, driving the gripper 9 to clamp the seedling in the moving groove 8 of the connecting block 5. The adjusting wheel 6 on the connecting block 5 cooperates with the adjusting rod 22, and transmits the force through the round tube 23 to adapt to seedlings of different thicknesses. The positioning screw 24 fixes the adjusted position of the components. Next, the first driver 11 drives the first servo motor 14 to operate through the connecting plate 26. The first servo motor 14 drives the straightening frame 12 to rotate. The steering rod 25 assists the straightening frame 12 to maintain stability and corrects the posture of the seedling on the gripper 9 to ensure that the seedling is vertical. Finally, the hydraulic cylinder 21 pushes the guide plate 17 on the frame 1, which works with the guide wheel 18 to maintain stable movement. The second servo motor 15 drives the cutting frame 13 to accurately insert the upright seedling into the substrate. After the cutting is completed, all components are reset and the next round of operation begins.
