Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and more particularly to a peanut cleaning machine with an adjustable automatic grading function. Background Art

[0002] Peanuts are also known as groundnuts and dicotyledonous plants. The veins of the leaves are reticular and the seeds are covered with peanut peels. Historically, they have been called longevity fruit, ground beans, fallen flower ginseng, ground pine, longevity fruit, fan beans, figs, ground fruits, and Chinese beans. Peanuts are grown to nourish and help prolong life. When peanuts are just pulled out, there is dirt on the surface, which needs to be cleaned. Existing agricultural production generally uses manual cleaning of peanuts, which has poor cleaning effect and low efficiency.
