Coal mine crushing device for gypsum mine mining

Abstract

The invention discloses a coal mine crushing device for gypsum mine mining. The device comprises a crushing box, a feeding opening formed in the top of the crushing box, a crushing structure rotationally connected with the interior of the crushing box, a driving structure arranged outside the crushing box and connected with the crushing structure, crushing plate structures arranged in the crushing box, an adjusting structure arranged between the other ends of the crushing plate structures and the crushing box, and a discharging structure arranged at an opening in the bottom of the crushing box. One ends of the crushing plate structures are hinged to the crushing box; the crushing plate structures are arranged at the two sides of the crushing structure; the crushing structure is arranged right under the feeding opening; and the distance between the crushing plate structures and the crushing structure can be adjusted through the adjusting structure. The coal mine crushing device for gypsum mine mining is simple in structure, convenient to operate, high in practicability and good in crushing effect when used for crushing a coal mine, the crushing degree can be adjusted according to needs, and various different requirements are met, so that the device can be widely applied and is beneficial to application and popularization.

Description

technical field [0001] The invention relates to the technical field of crushing for coal mines used in gypsum mine exploitation, in particular to a coal mine crushing device for gypsum mine exploitation. 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. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts, and mining faces. In...
