Grain screening machine capable of removing impurities in screen mesh

Abstract

The invention discloses a grain screening machine capable of removing impurities in a screen mesh and relates to the technical field of grain screening machines. The grain screening machine comprisesa cylindrical screen mesh device, an impurity removal rocker bar and a base. The cylindrical screen mesh device comprises a cylindrical screen mesh, a conical screen mesh and a screen mesh fixing seat. The cylindrical screen mesh is fixed to the inner surface of the screen mesh fixing seat. The conical screen mesh is fixed to the inner surface of the screen mesh fixing seat. A cross is arranged onthe inner surface of the cylindrical screen mesh. A motor is fixed to one surface of the cross. The motor is matched with a third through hole of a rotary disk device. One end of the conical screen mesh is provided with a circular pipe. A through hole of the circular pipe is matched with the impurity removal rocker bar. The base comprises a fixed base, supporting columns and an impurity outlet plate. The impurity outlet plate is fixed to one surface of the base. A collection seat is fixed to the peripheral side faces of the supporting columns. Under the action of the cylindrical screen mesh device and the impurity removal rocker bar, the grain screening machine has the characteristics of being capable of centralizing impurities not passing the screen meshes and then discharging the impurities in a centralized mode, and the problems that the screening speed is low, and impurities hinder the grain screening speed and screening effect are solved.

Description

technical field [0001] The invention belongs to the technical field of grain screening machines, in particular to a grain screening machine for removing impurities in a screen. Background technique [0002] In the process of grain production, it is necessary to screen various sizes of soil and sand in the grain, so as to reduce the impurities in the grain. At present, there are many kinds of grain cleaning equipment at home and abroad, such as cylinder initial cleaning sieve, vibrating cleaning sieve, flat rotary sieve, stone removal machine, etc., but the screening speed of these cleaning equipment for grain is low, and there are still some ears of grain in the grain Such impurities lead to the problem of many impurities in the screening machine during the screening process. Impurities hinder the screening speed and screening effect of the grain, and the screening process of the screening machine is also prone to the problem of material jams. [0003] The present invention...
