Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a peanut cleaning machine. Background technique [0002] At present, there is basically no corresponding mechanical operation for the cleaning of peanuts. Every process such as handling, picking, and raising the field is completely completed manually, especially the light impurities mixed in peanuts such as peanut seedlings and residual films. Manual cleaning is labor-intensive and low in efficiency. The existing cleaning devices in the market have a relatively complicated structure and high cost. The cleaning efficiency and cleaning effect of peanuts are low, and it is difficult to meet large-scale production. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a peanut cleaning machine which is reliable in operation, convenient in operation, good in screening effect, high in work efficiency and...
