mine coal crusher

Abstract

The invention discloses a mining coal crusher, which comprises a machine body shell, a support frame, a beam, a support plate, a material inlet, a material outlet, a reduction motor, a pulley, a belt, a driven pulley, a transmission gear device, a crushing device, Receiving device, the front and rear of the bottom of the body shell are respectively welded with support frames of rectangular structure, the front and rear two support frame brackets are welded with beams, the right side of the support frame is welded with a support plate, and the support plate is connected to the right side of the body shell. Fixed, the top of the body shell is welded with a material inlet, and the bottom is welded with a material outlet. The back of the body shell is equipped with a deceleration motor through bolts. The deceleration motor is fixed with the pulley, and the pulley drives the driven pulley through the belt. Rotate, and the belt pulley simultaneously drives the transmission gear unit to operate. The invention facilitates the crushing of the crushing column, avoids falling too fast, reduces the amount of recycled materials, increases the crushing efficiency of coal, avoids waste caused by cost, and reduces the cleaning work of operators.

Description

technical field [0001] The invention relates to a crusher, in particular to a mining coal crusher. Background technique [0002] Coal is a solid combustible mineral that was gradually formed by ancient plants buried in the ground through complex biochemical and physical chemical changes. The finished product of coal excavation is large and needs to be broken into small pieces, which is convenient for transportation and combustion. The traditional crusher adopts extrusion type, which is easy to increase coal and cause a large amount of coal powder, resulting in waste of cost, and the amount of recycled material in the crushing process is large. The work efficiency is low, and it is easy to cause fragments to accumulate at the discharge place, which affects the normal use of the machine. It needs to be cleaned by the staff, and further improvement is needed. Contents of the invention [0003] The object of the present invention is to provide a mining coal crusher to solve t...
