Coal mine crushing device for coal mining

Abstract

The invention discloses a coal mine crushing device for coal mining. The coal mine crushing device comprises a crusher, a discharging channel and a dust removal mechanism; a feeding port and a discharging port are formed in the crusher; the discharging port communicates with the discharging channel; the dust removal mechanism comprises a water spraying unit and a dust suction unit; the water spraying unit comprises a push rod, an inclined plate, a solution cylinder and a first piston used in cooperation with the solution cylinder; the solution cylinder is filled with water; and the dust suction unit further comprises an air cylinder, a plurality of pressure springs and a second piston used in cooperation with the air cylinder. According to the coal mine crushing device, corresponding water spraying cooling treatment can be carried out on a coal mine which is just rolled and crushed, and dust removal can be carried out on the coal mine through sprayed water; and meanwhile, dust is further removed through the dust suction unit, and through double dust removal operation, the crushing device can have a better dust removal effect.

Description

technical field [0001] The proposal belongs to the technical field of coal mine mining equipment, and specifically relates to a coal mine crushing device for coal 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. [0003] In the process ...

AI Technical Summary

Problems solved by technology

However, in the actual process of crushing coal mines, there are the following problems: After the coal mines are crushed, they need to be transferred to a designated place. When the coal mines are transferred from the crushing device, the huge dust in the coal mines not only seriously threatens the life and health of the relevant operators, but also In the long run, it will cause considerable harm to the surrounding environment; at the same time, during the crushing process of coal mines, the temperature between the crushed coal mines is quite high. In summer or in high temperature weather, it is easy to cause coal mines to spontaneously ignite. big security risk

This patent solves the dust generated by the coal mine crushing device during the crushing process, but does not solve the large amount of dust generated when the coal mine is transferred after the coal mine is crushed; it fails to solve the safety hazard that the high temperature may cause spontaneous combustion of the coal mine after crushing; at the same time, the patent The crushing device of the scheme relies on power to achieve the target operation, which increases the cost of use
