Coal mine crusher for mining

Abstract

The invention discloses a coal mine crusher for mining. The crusher comprises a shell and supporting legs, the shell is supported by the supporting legs, a front cover body is mounted on the left endof the shell, a rear cover body is mounted on the right end of the shell, a turnover body and the shell are coaxial, a rotating shaft is mounted in the turnover body, crushing rods are mounted on therotating shaft, and are evenly distributed around the axis of the rotating shaft, meanwhile, the crushing rods are evenly distributed in the extension direction of the axis of the rotating shaft, theends of the crushing rods are rotatably connected with swing teeth, guide rods are arranged at the positions, corresponding to the breaking rods, of the side face of the turnover body and are evenly distributed around the axes of the guide rods, meanwhile, the guide rods are evenly distributed spirally in the extension direction of the axes of the guide rods, guide wheels are arranged at the position, between contact faces of the turnover body and the shell, close to the bottom, of the inner wall of the shell, a feeding opening is formed in the front cover body, a feeding hopper is mounted onthe corresponding position of the feeding opening, and a discharging opening is formed in the rear cover body. The coal mine crusher has the advantages that uniform breaking is achieved, blockage isprevented, and work efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of coal mine mining, and in particular relates to a coal mine crusher for mining. Background technique [0002] Coal mines are areas where human beings mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. Coal mines are often very large when they are mined, and large pieces of coal will be crushed for the convenience of transportation; the existing crushers Both use the gravity of the coal itself to drop, and the material cannot be fed uniformly, which will cause damage to the crusher and seriously block the crusher, thereby affecting the work progress. Therefore, it is particularly important to solve the above-mentioned problems. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and provides a coal mining crusher for uniform crushing, blocking prevention and high working efficiency.
