A crushing device for coal mining

Abstract

The invention discloses a crushing device for coal mining. The device comprises a sliding rail, a sliding groove, a supporting plate, a fixed bolt, a rotating shaft, a first rotating cylinder, a firstbevel gear, a first electric motor, a placing trough, a second bevel gear, a sliding frame, a fixed shaft, second rotating cylinder, a linear motor, a fixed block, a fixed column, a roller, a rotating column, a connecting block, a connecting rod, a fixed rod, an electric push rod, a pressure plate, a fixed shell, a second electric motor, a knife seat, a coal mining knife, a fixed seat, a fixed bar, a baffle, a conveyor belt and a third electric motor. The crushing device for coal mining is simple in structure and novel in design, is convenient for workers to adjust the placing position of thedevice, and at the same time, is convenient to stably fix the adjusted device so as to ensure stable mining of the coal mining knife, and is convenient for the position adjustment of the coal miningknife so as to improve the using range of the device, and is convenient for the linear motor to stably push a sliding frame to move stably so as to make the using convenient.

Description

technical field [0001] The invention relates to a crushing device, in particular to a crushing device for coal mining, which belongs to the technical field of coal mining applications. Background technique [0002] A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts, and mining faces. Coal is the main solid fuel and a kind of combustible organic rock. It is formed by the luxuriant plants growing in a certain geological age, gradually accumulating into thick layers in a suitable geological environment, and buried in the bottom of the water or in the sand, and formed after a long geological age of natural coalification. [0003] At present, in the mining process of coal mines, some coal mining devices are not easy to move and fix in the coal mine, which affects the mining efficiency of the coal mine. The coal is not easy to discharge, which increases the labor intensity of the workers, reduc...

AI Technical Summary

Problems solved by technology

[0003] At present, in the mining process of coal mines, some coal mining devices are not easy to move and fix in the coal mine, which affects the mining efficiency of the coal mine. At the same time, during the mining process, the mining range of the coal mine is small, which greatly reduces the practicality of the device. The coal is not easy to discharge, which increases the labor intensity of the workers, and at the same time reduces the working efficiency of the device and affects the use process
