Abstract

The invention relates to a screening device, in particular to a simple vibrating screening device of grain. The vibrating screening device comprises a taper screen. Screen walls are arranged on the periphery of the screen. A rotating shaft is fixed vertically in the center of the screen. The screen walls are connected with the rotating shaft through connecting rods. A stepped shaft is arranged above the rotating shaft. A semi-sphere protrusion is arranged on the protruding lower surface of the stepped shaft. A shaft sleeve connected with the stepped shaft is arranged below the stepped shaft and is fixed on a machine frame. Four protruding blocks are evenly distributed on the upper surface of the shaft sleeve. The protruding blocks correspond to the protrusion in position. According to the technical scheme, the screening device is simple in structure, low in cost and good in screening effect.

Description

technical field [0001] The invention relates to a screening device, in particular to a simple vibration screening device for grain. Background technique [0002] Before the grain is further processed, it is usually necessary to remove the impurities, usually after the sieving process, it is washed and dried in the sun. At present, for the screening of grain, the special screening device is not only expensive but also occupies a very large area, which is not suitable for a large number of small enterprises. Therefore be badly in need of a kind of simple in structure, cost is low and the device with good screening effect. Contents of the invention [0003] The object of the present invention is to provide a device with simple structure, low cost and good screening effect. [0004] In order to achieve the above object, the present invention provides a vibrating screening device, which includes a tapered screen, screen walls are arranged around the screen, the center of the ...
