Underground variable-diameter negative-pressure dust collection crusher for coal mine and use method thereof

Abstract

The invention discloses an underground variable-diameter negative-pressure dust collection crusher for a coal mine and a use method thereof. The underground variable-diameter negative-pressure dust collection crusher comprises a shell, a connecting rod, a supporting rod, a base, a reinforcing rib plate, a connecting pipe, a vertical pipe, a sealing cover, a negative pressure fan, a shell, a fixing frame, a first motor, a centrifugal impeller, a protective cover, a second motor, a bearing plate, a positioning frame, trundles, a rotating shaft, a dustproof iron gauze, a charging box, a spring, crushing wheels, a first material guide plate, a second material guide plate, an efficient filter, a worm, a connecting shaft, a worm wheel and a sealing gasket. The underground variable-diameter negative-pressure dust collection crusher can be used for crushing underground materials, crushing is achieved through rolling of the two crushing wheels, and the crushing efficiency is high. The crushing wheels are driven through a crushing wheel speed reduction driving mechanism, the rotating speed of the crushing wheels can be reduced, and therefore the crushing force of crushing is improved. Two negative-pressure dust collection mechanisms are arranged, so that negative pressure dust collection can be conducted on the two sides of the shell, flow guiding can be provided for generated flying dust, flying dust overflowing is avoided, the dustproof effect is good, and harm to operators is avoided.

Description

technical field [0001] The invention relates to a crusher and a using method thereof, in particular to an underground variable-diameter negative pressure dust suction crusher used in coal mines and a using method thereof, belonging to the technical field of crusher application. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, which 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, which is an open-pit coal mine. [0003] When the underground coal mine needs to be mined, it is generally necessary to use a crusher for crushing to reduce the volume of the material; when the existing crusher is used, it is easy to generate dust and cause great harm to the operator. Therefore, in view of the above problems, an underground variable-diameter negative pressure...
