Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato cleaning, in particular to a surface soil removing device for sweet potato harvesting. Background Art

[0002] Yams, also known as sweet potatoes and sweet potatoes, are rich in protein, starch, pectin, cellulose, amino acids, vitamins, and various minerals, earning them a reputation as a "longevity food." They offer benefits such as anti-cancer, heart protection, prevention of emphysema and diabetes, and weight loss. Harvesting sweet potatoes at the right time is crucial. Harvesting too early results in lower yields, while harvesting too late exposes them to freezing, hindering storage. After harvesting, a large amount of soil accumulates on the surface of the sweet potatoes, necessitating a surface desoiling device.

In addition, the device uses a pulley to drive the belt to drive multiple roller brushes to rotate together. Due to the small contact area between some belts and the belt, they cannot be driven or cannot rotate, thus affecting the cleaning and transmission effect of the sweet potatoes.
