The two support spring frames 306 are respectively in contact with the inner sides of the two conveyor belts 303;

[0021] In this embodiment, the soil around the roots of the scallions is loosened by the soil loosening mechanism 4. Then, the driving motor 1 304 is started to drive the conveyor roller 302 to rotate, and then the conveyor roller 302 drives the conveyor belt 303 to move. Driven by the conveyor belt 303, the upper part of the scallions can move backward. By adjusting the spring tension in the tension spring frame 305, scallions of different thicknesses and lengths can be conveyed. When the tension spring frame 305 and the support spring frame 306 are used in combination, clamping force and tension are provided for the conveyor belt 303 respectively, reducing the dropping phenomenon caused by unstable clamping, and enabling the scallions to be more firmly supported and conveyed during the conveying process. The scallions are collected by the sorting and collecting mechanism 5.

[0022] Further, the soil loosening mechanism 4 includes a guide rail 401, an adjustment slot 404 and a triangular plow 408. A connecting frame 402 is installed on one side of the guide rail 401, and an adjustment block 403 is installed on the surface of the connecting frame 402. The adjustment slot 404 is opened on the lower surface of the spring roller frame 301, and the outer wall of the adjustment block 403 is slidably connected to the inner wall of the adjustment slot 404.

[0023] By inserting the triangular plow 408 into the soil, as the vehicle frame 1 moves forward, the triangular plow 408 can loosen the soil around the roots of the scallions. With the setting of the first nut, the adjustment block 403 and the adjustment slot 404, the distance between the triangular plows 408 can be adjusted. With the setting of the second nut and the adjustment rod 409, the penetration depth of the triangular plow 408 can be adjusted, so as to adapt to different ridging heights of the scallions.

[0024] Further, the sorting and collecting mechanism 5 includes a fixed frame 501. The fixed frame 501 is installed at the rear side of the vehicle frame 1. A driving motor 2 502 is installed on one side of the fixed frame 501. Both sides of the outer wall of the fixed frame 501 are rotatably connected with a rotating shaft 503.

[0025] When the conveyor belt 303 drives the upper part of the scallions to move backward, the lower part of the scallions is blocked by the conveyor belt 504 and thus falls backward, causing the scallions to fall on the conveyor belt 504. At the same time, the driving motor 2 502 is started to drive the rotating shaft 503 to rotate, and the rotating shaft 503 drives the conveyor belt 504 to move, so as to convey the scallions and collect them into the collecting box 505 on the side.

[0027] The working principle and usage process of the present utility model are as follows: The operator inserts the triangular plow 408 into the soil. As the vehicle frame 1 advances, the triangular plow 408 can loosen the soil at the roots of the green onions. Through the settings of the first nut, the adjusting block 403 and the adjusting groove 404, the distance between the triangular plows 408 can be adjusted. Through the settings of the second nut and the adjusting rod 409, the penetration depth of the triangular plow 408 can be adjusted, so as to adapt to different ridging heights of the green onions. Then, by starting the driving motor 1 304 to drive the conveyor roller 302 to rotate, and further enabling the conveyor roller 302 to drive the conveyor belt 303 to move. Driven by the conveyor belt 303, the upper part of the green onions can move backward, so as to convey green onions of different thicknesses and lengths.

When the conveyor belt 303 drives the upper part of the green onions to move backward, the lower part of the green onions is blocked by the conveyor belt 504 and thus falls backward, causing the green onions to fall on the conveyor belt 504. At the same time, start the driving motor 2 502 to drive the rotating shaft 503 to rotate, and the rotating shaft 503 drives the conveyor belt 504 to move, so as to convey the green onions and collect the green onions into the collection box 505 on the side.
