Abstract

The invention relates to the technical field of coal mines, and discloses a crushing device for coal mining, which comprises a first device body, the top of the first device body is provided with a coal inlet, the inner wall of the coal inlet is fixedly connected with a funnel, the inner top wall of the first device body is fixedly connected with a beating plate, and the inner wall of the first device body is fixedly connected with a fixing plate. The top of the fixing plate is movably connected with a fixing shaft, the outer wall of the fixing shaft is movably connected with a gear disc, the top of the gear disc is fixedly connected with a rotating plate, and the outer wall of the first device body is fixedly connected with a supporting plate. According to the crushing device for coal mining, the purpose of good crushing effect is achieved, the problem that a common crushing device is poor in crushing effect is solved, secondary crushing of a whole coal mine is avoided due to the good crushing effect, the coal mine crushing working process of a user is reduced to a certain degree, and then the coal mine crushing working time is shortened; and the working efficiency of coal mine crushing is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a crushing device for coal mining. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine, and most of the coal mines in my country are underground coal mines. [0003] With the continuous mining of coal mines, people began to pay attention to the equipment required for mining. Among them, the crushing device used for coal mining has become an indispensable coal mining device. The current crushing devices on the market generally have the problem of poor crushing effect. If it is not good, it will lead to the secondary crushing of the coal mine, which will increase the working p...
