The leeks are harvested in combination with the digital and intelligent transmission, baling and collection devices, realizing the integration of picking, collecting and bundling, which greatly improves the efficiency of the integration of picking, collecting and bundling of leeks.

[0044] In one embodiment of the present invention, please refer to Figure 1-Figure 6The crawler wheel mechanism includes a crawler 4, a wheel hub 5 and a linkage shaft 7. The linkage shaft 7 is rotatably mounted in two groups at the bottom of the support plate 6. The wheel hub 5 is fixedly mounted in one group at each end of each linkage shaft 7. The crawler 4 is arranged on the wheel hub 5.

[0045] The reel cutting mechanism comprises a blade 1, a chain link 2 and a sprocket 3, wherein the sprocket 3 is rotatably mounted on a frame 8, and two groups of sprockets 3 are provided, and a chain link 2 for driving the blade 1 to move is further provided between the two groups of sprockets 3;

[0048] The double-stage conveyor belt mechanism includes a conveyor belt 32 , and two groups of conveyor belts 32 are arranged on the frame 8 .

[0049] In this embodiment, the harvester should have the ability to adapt to different planting environments, be able to move easily and accurately position. According to field investigation and measurement, the diameter of leek is about 5-8mm, the proposed design cutting range is 10-12mm, and the chain link 2 is a single-row single-hole design; the frame 8 is also provided with a first connecting shaft 16, a shaft 15, a middle shaft 14 and a second connecting shaft 17, and the first connecting shaft 16 side device is mutually meshed with a first gear 9, a second gear 10, a third gear 11 and a fourth gear 12. Considering the optimization design of the mechanical transmission system, the mechanical transmission system is the power source of the intelligent leek harvester integrated with harvesting and bundling, and its transmission efficiency and stability are crucial to the working effect of the entire equipment. By optimizing the structure and parameter design of the transmission system, the power transmission efficiency can be improved, the energy loss can be reduced, and the working efficiency of the equipment can be improved. Through the transmission of the first gear 9, the second gear 10, the third gear 11 and the fourth gear 12, the conveyor belt 32 is used to transport the harvested leek. Since the gravity-sensing falling bundling device at the rear end requires a certain falling time, the stability and reliability of the mechanical structure.

Through the overall structure analysis of the whole machine, due to the need to bear the power of the conveyor belts 32 at both ends and the front gear transmission, a frame 8 is proposed to be designed as follows Figure 1 As shown, the mechanism is then subjected to finite element analysis. Due to the gravity of the leek and the gravity of the conveyor belt 32, the yield strength is loaded with a pressure of 100N, and the deformation displacement degree of the mechanism is relatively low, so it is suitable for the frame 8 structure of the intelligent leek harvester with integrated harvesting and bundling. The double-stage conveyor belt mechanism can effectively reduce the falling time difference and avoid blockage and accumulation of leeks before bundling.

[0053] In this embodiment, the weighing box 23 is combined with the structure of the single-chip microcomputer to realize the automatic weighing function. By setting a certain weight, the leeks fall after reaching the set gravity. The top is a plate-like structure designed to open and close inward, so that the leeks can fall into the weighing box 23 for bundling. The back is a baffle 19 to prevent the leeks from spilling. The leeks are gathered to the middle of the weighing box 23 by the push rod connecting plates 21 at both ends and the small push rod 22 for bundling. The first connecting rod 24 and the large push rod 18 push the bundled leeks into the container 29 through the circular rotation and translation connecting rod movement.
