Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a leek root soil screening device. Background Art

[0002] In the process of planting leeks, fresh and healthy leek roots are usually used as the rhizomes for planting. Before planting, the soil on the surface of the rhizomes needs to be removed, and the leek roots need to be screened and pruned. When the leek roots are dug out from the original soil, there is a lot of soil on the surface of the rhizomes, which needs to be screened through a sieve. Now, in the screening process of leek roots, a drum screen is usually used to screen the soil, and a conveyor belt is installed at the feed end of the drum screen to transport the leek roots to the inside of the drum screen. In the current soil screening device, the drum screen and the conveyor belt are usually driven by separate motors. The production cost is high and multiple power interfaces are required during on-site operations, which makes it inconvenient to use on-site. Utility Model Content
