Grain grinding device capable of intermittently discharging and automatically screening

Abstract

The invention relates to the technical field of grain grinding, and discloses an intermittent discharging and automatic screening grain grinding device which comprises an equipment main body, a grinding box is arranged in the equipment main body, a discharging mechanism is arranged in the grinding box, and a feeding hopper is fixedly connected to the upper end of the grinding box; a supporting plate is arranged below the grinding box, and a first motor is fixedly connected to the upper portion of the left end of the supporting plate. According to the grain grinding device capable of achieving intermittent discharging and automatic screening, after ground products fall to the upper end of the screen plate, a second motor drives a crank to rotate so as to drive a long sliding block to slide left and right in a reciprocating mode through a connecting rod, then the screen plate continuously shakes, and qualified ground products fall into a collecting box below through the screen plate; and unqualified grinding products roll into the tubular spiral conveyor and are conveyed into the feeding hopper again for secondary grinding, so that the grinding products are automatically screened and automatically recycled for secondary grinding, and the utilization rate of raw materials is increased.

Description

technical field [0001] The invention relates to the technical field of grain grinding, in particular to a grain grinding device capable of intermittent feeding and automatic screening. Background technique [0002] Grain grinding, also known as grain processing, refers to the production activities of hulling, milling and finishing grains such as rice, millet, wheat and sorghum. When the general grain grinding device is used, the grain to be ground is put into the device through a hopper for grinding, but due to the excessive input of raw materials, it is easy to accumulate inside the equipment, and the grinding mechanism inside the grinding device cannot fully grind the grain. The grinding efficiency is low, and machine blockage may occur; in addition, the general grinding device does not have the function of automatically screening the grinding products, and cannot automatically remove the incompletely ground grains, which undoubtedly causes waste of materials and reduces ...

Problems solved by technology

When the general grain grinding device is used, the grain to be ground is put into the device through a hopper for grinding, but due to the excessive input of raw materials, it is easy to accumulate inside the equipment, and the grinding mechanism inside the grinding device cannot fully grind the grain. The grinding efficiency is low, and machine blockage may occur; in addition, the general grinding device does not have the function of automatically screening the grinding products, and cannot automatically remove the incompletely ground grains, which undoubtedly causes waste of materials and reduces In order to ensure the quality of the grinding product, manual screening will consume a lot of time and energy, which cannot meet the actual production needs.

[0003] Aiming at the deficiencies of the prior art, the present invention provides a grain grinding device capable of intermittent feeding and automatic screening, which has the advantages of improving grinding efficiency, preventing machine blockage, and automatically screening grinding products, and solves the problems of low grinding efficiency and low grinding efficiency of general grinding devices. The problem of not being able to automatically screen the ground product
