Coal crushing device facilitating movement and manual maintenance

Abstract

The invention discloses a coal crushing device facilitating movement and manual maintenance, and relates to the technical field of coal crushing. The coal crushing device includes a feeding port, a crushing chamber and a discharging port, the feeding port is formed in the top of the crushing chamber, the discharging port is arranged at the bottom of the crushing chamber and corresponds to the feeding port in position, the crushing chamber is internally provided with a first crushing device and a second crushing device, the first crushing device includes a crushing roller, a buffer arm and a motor, the buffer arm is horizontally arranged on the side wall of the crushing chamber, one end of the buffer arm is arranged on the side wall of the crushing chamber, and the crushing roller is arranged at the other end of the buffer arm; and the second crushing device and the first crushing device are of the same structures, and the second crushing device and the first crushing device are symmetrically arranged with respect to the center of the feeding port. The coal crushing device is small in vibration during operation, uniform in crushing granularity and high in crushing efficiency, and has the application and promotion value.

Description

technical field [0001] The invention relates to the technical field of coal crushing, in particular to a coal crushing device that is convenient for movement and manual maintenance. Background technique [0002] In the process of coal mining, coal crushing is an indispensable operation link. Raw coal or bituminous coal can only be transported to the next link for processing and processing after crushing. The quality of the crushing work determines the effect of the remaining reprocessing links and efficient utilization, but the performance of the crushing device directly determines the effect of material crushing. The coal crushers in the prior art generally have the disadvantages of strong vibration, uneven crushing particle size, and low crushing efficiency. It is difficult to achieve the ideal operating effect, and it is difficult to observe the internal conditions of the crusher, which leads to the inability to make reasonable adjustments and maintenance of the crusher. ...
