A multi-stage coal mine crushing device

Abstract

The invention discloses a multistage coal mine crushing device which comprises an inclined bottom guide mounting cylinder, wherein a feeding and crushing module is upwards arranged at the left upper corner of the inclined bottom guide mounting cylinder; a screw lifting module is arranged at the right upper corner of the inclined bottom guide mounting cylinder; the feeding and crushing module comprises a crushing mounting cylinder which is vertically arranged at the left upper corner of the inclined bottom guide mounting cylinder; a crushing and feeding drum is concentrically arranged at a middle position inside the crushing mounting cylinder by virtue of a supporting rotating shaft arranged in a penetrating manner; the crushing and feeding drum comprises a crushing operation cylinder matched with the crushing mounting cylinder; a plurality of feeding partition supporting columns are outwards arranged on the supporting rotating shaft in equal angle and matched with the crushing operation cylinder; discharging holes are uniformly formed between adjacent feeding partition supporting columns in a penetrating manner. The multistage coal mine crushing device disclosed by the invention has the advantages of being compact in structural design, centralized in power source, safe in feeding, high-efficiency in crushing, capable of saving time, labor and space and the like.

Description

technical field [0001] The invention relates to a coal mine machine, in particular to a multistage coal mine crushing device. Background technique [0002] Coal mine crusher is a crushing equipment that breaks coal lumps and grinds them into coal powder. The process of the coal mine crusher is a process in which coal is crushed and its surface area is continuously increased. The current coal mine crushing device adopts the traditional assembly line crushing structure, which results in a long crushing cycle, a large area of ​​the device, and increased energy consumption for transportation. Adopting the traditional feeding structure causes the crushing device to be stuck easily and the failure rate is high. [0003] In order to solve the above problems, the present invention is proposed, which overcomes the problems of the currently used coal mine crushing device, such as the adoption of the traditional assembly line crushing structure, resulting in a long crushing period, a ...

[0003] In order to solve the above problems, the present invention is proposed, which overcomes the problems of the currently used coal mine crushing device, such as the adoption of the traditional assembly line crushing structure, resulting in a long crushing period, a large area occupied by the device, and increased energy consumption for transshipment. Due to the traditional feeding structure of the crushing device, the crushing device is easily stuck and the failure rate is high, so the present invention has the advantages of compact structure design, centralized power source, safe feeding, efficient crushing, time-saving, labor-saving and space-saving, etc.
