Problems solved by technology

[0003] In the processing of coal mines, coal mines need to be crushed, and a coal mine crushing device will be used. However, the existing coal mine crushing devices directly place the coal mines between two crushing pools for crushing processing. When crushing larger coal mines, it is difficult to get stuck between the two crushing teeth, so there are problems of difficult crushing and insufficient crushing

Abstract

The invention belongs to the technical field of coal mine processing, in particular to a crushing device for coal mine processing, which includes a support shell, a support plate is fixedly installed on the outer wall of the middle part on one side of the support shell, and a support plate is fixed on the outer wall of the top side of the support shell. A first groove is provided, and the inner walls at both ends of the first groove are connected to the same supporting bottom plate through a rotating shaft. The crushing device for coal mine processing is provided with a supporting bottom plate and a supporting top plate, and a first electric guide rail, a second electric guide rail and a second electric telescopic rod are arranged between the supporting bottom plate and the supporting top plate, and at the same time, a The pressing plate is provided with a bump at the bottom of the pressing plate. The coal mine can be placed between the pressing plate and the supporting base. Drive the pressing plate to press on the coal mine to achieve effective crushing of the coal mine.

Description

technical field [0001] The invention relates to the technical field of coal mine processing, in particular to a crushing device for coal mine processing. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. [0003] In the processing of coal mines, coal mines need to be crushed, and a coal mine crushing device will be used. However, the existing coal mine crushing devices directly place the coal mines between two...
