The invention discloses an automatic grain
impurity removal device, and relates to the technical field of grain
impurity removal, the automatic grain
impurity removal device comprises a mounting rack, an impurity removal box arranged at the top of the mounting rack, a shelling box arranged at the top of the impurity removal box and a shelling box arranged at the top of the shelling box in a communicating manner, a receiving hopper is mounted at the bottom of the impurity removal box, and splitter plates are arranged on the two side surfaces of a longitudinal beam; an arc-surface-shaped rolling groove is formed in the top surface of the bearing plate; a rolling mechanism is arranged in the rolling groove; a one-way transmission
assembly is arranged in the middle of the bottom face of the bearing plate. A shifting mechanism is arranged in the lower part of the receiving hopper; according to the device, the
grinding mechanism is matched with the transmission
assembly and the shifting mechanism, so that automatic hulling, impurity removal and automatic sorting operation can be conveniently carried out on hulled and impurity-removed grains, the convenience of hulling, impurity removal and
particle sorting operation on the grains is effectively improved, and the efficiency of impurity removal on the grains is greatly improved; and meanwhile, small grains in the grains can be conveniently sorted out, and the finished product quality of the grains after impurity removal operation is improved.
