Classifying device capable of removing metal impurities

Abstract

The invention discloses a sorting device capable of removing metal impurities, comprising a bottom plate, the upper surface of the bottom plate is fixedly connected with a wallboard, two first rotating shafts are plugged into the front of the wallboard, and the first rotating shaft The surface is fixedly connected with a first transmission wheel, and the two first transmission wheels are connected through a composite belt, and the composite belt is composed of a first belt and a second belt, and the second belt is located on the inner side of the first belt. A magnet strip is fixedly connected to the surface of the second belt, and two second rotating shafts are also fixedly connected to the front of the wallboard. The invention makes the device work, and the grain material is discharged through the feeding mechanism and the upper surface of the compound belt, and the grain will be transported along with the transmission of the compound belt. When the grain moves to one side of the compound belt, the grain will be under the action of gravity It is dumped into the first storage chamber, and the metal impurities will be attached to the lower surface of the composite belt under the adsorption of the magnet strips and continue to be transported forward.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a sorting device capable of removing metal impurities. Background technique [0002] In the process of agricultural production, it is often necessary to screen impurities such as grains. In the process of grain harvesting, impurities of metal particles are often mixed in the rice, so after the rice harvesting is completed, it is necessary to remove impurities. At present, the wind-driven impurity removal method is mainly used for the metal impurities in the rice, that is, the rice is thrown down freely. Because the weight of the rice and impurities is different, the offset distance is also different under the blowing action of the wind, so as to achieve separation. effect, but the efficiency of this method is low, and the separation effect is not obvious, so it cannot meet the production needs of large quantities.
