Description

Technical Field

[0001] The utility model relates to the technical field of leek harvesting, in particular to a semi-automatic leek harvester. Background Art

[0002] The number of times leeks are harvested each year depends on the growth, fertilization and market conditions of leeks. In winter and spring, leeks can be harvested three times in the greenhouse. Although the quality is good in autumn, in order to cultivate root stocks and lay the material foundation for the growth of the greenhouse, it is advisable to harvest 1-2 times. The standard for cutting leeks is 7 leaves and 1 heart. It is best to harvest in the early morning, and it is advisable to cut to 3-4 cm yellow leaf sheath on the bulb. Each subsequent cut should be slightly higher than the previous one to ensure normal growth. The yield is relatively low in the first 1-2 years after planting, and the 3-6 years are the peak growth period with the highest yield. After 10 years, it enters the aging stage and should be divided and transplanted in time.

[0003] Traditional leek harvesting operations are usually completed through manual labor, using manual tools (such as sickles) to harvest leeks one by one, and sorting and stacking them together. However, the efficiency of manual leek harvesting is relatively low, which cannot meet the needs of large-scale planting or rapid harvesting, affecting the yield and sales time. At the same time, manual leek harvesting requires a lot of manpower input and has high labor intensity, which easily leads to farmers' fatigue and low work efficiency. Therefore, there are certain defects. Utility Model Content

[0072] The specific working principle of the semi-automatic leek harvester of the utility model is as follows:

[0073] During use, the frame 1 is moved to a suitable position, and then the first drive motor 31, the second drive motor 92 and the electric push rod 21 are started. Starting the electric push rod 21 can drive the first connecting rod 22 to move toward the front side or the rear side of the frame 1. When the first connecting rod 22 moves toward the rear side, the gathering claw 24 can be driven to rotate by the second connecting rod 23, and the gathering claw 24 is gathered toward the middle position, so that the leeks can be gathered toward the middle position. Then the first drive motor 31 drives the knife disc 32 and the blade 33 to rotate. The leeks can be cut, and the second driving motor 92 drives the driving sprocket 93 to rotate. During the rotation process, the driving sprocket 93 can drive the driven sprocket 94 to rotate through the transmission chain 95, thereby driving the rotating rod 6 to rotate axially. Due to the mutual engagement of the gears 91, the rotation directions of the two rotating rods 6 are opposite, and the conveyor belt 8 can also operate to the opposite side, so that the leeks can be displaced along the surface of the conveyor belt 8, and the leeks change from the original vertical state to the longitudinal state, and finally can be placed flat in the collection basket 4, thereby completing the harvesting of the leeks;

[0074] Then the electric push rod 21 drives the first connecting rod 22 to move toward the front of the frame, so that the two gathering claws 24 separate and open from each other, and the next leek can be gathered. In conjunction with the cutting component 3, the first transmission roller 5, the rotating rod 6, the second transmission roller 7, the transmission belt 8 and the driving component 9, the leek can be harvested continuously.
