Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a light green onion harvester. Background Art

[0002] Green onions are a common vegetable and an indispensable seasoning in Chinese cuisine. After planting green onions, the correct harvesting method can ensure the quality and yield of green onions. Green onion harvester is an agricultural machinery equipment that can automatically harvest green onions, which can effectively improve farmers' harvesting efficiency, save labor, reduce agricultural costs, and increase farmers' income. The working principle of the green onion harvester is that it first uses a coulter to arch the green onions from the ground, and then the harvesting wheel drives the conveyor belt to collect the green onions, and finally collects the green onions into the harvesting box. It can effectively improve the harvesting efficiency, save labor, reduce agricultural costs, and increase farmers' income.

[0003] In the prior art, when a green onion harvester takes green onions out of the soil, a large amount of soil is easily taken out from the roots of the green onions. The existing soil shaking function is achieved by the shaking generated by mechanical driving during the transportation process. However, since the soil at the roots of the green onions is relatively moist, some of the soil is not shaken off cleanly during the shaking process. In addition, the planting density and growth thickness of green onions are different. When the green onions are dug by the harvesting knife, the bottom of the green onions are easily cut off. Therefore, we propose a lightweight green onion harvester to solve the above problems. Utility Model Content
