Coal mining stone crushing and conveying device

Abstract

The invention discloses a coal mining stone crushing and conveying device which comprises a crushing shell and a mounting frame. A jaw plate is hinged to the top end of one inner side of the crushingshell, a crushing roller matched with the jaw plate is fixedly mounted at the inner top end of the crushing shell through a bearing, a filter screen is arranged between an end cover and the inner front end of the crushing shell, a conveying frame is welded at the front bottom end of the crushing shell, a conveying belt body is mounted inside the conveying frame and positioned at the end of the filter screen, gear plates in transmission connection with the conveying belt body are arranged on two sides of the front end of the conveying frame, the mounting frame is fixedly connected with two sides of the conveying frame through steel plates, and a collection box is movably mounted at the bottom of the crushing shell. The coal mining stone crushing and conveying device is simple and reasonablein structural design, convenient to operate and adjust, safe, stable, wide in applicable range and beneficial to popularization, coal briquettes are conveniently crushed, screened and transported, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a stone crushing and conveying device for coal mining. 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. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shaft...

AI Technical Summary

Problems solved by technology

When coal mines are mined, most of the coal blocks are relatively large and are inconvenient to transport. Therefore, the coal blocks need to be crushed after mining, but the broken coal blocks in the mine need to be transported manually, which not only consumes a lot of labor, but also wage efficiency. Low, the traditional conveying device has a single and fixed structure, and the length is not easy to adjust. At the same time, coal blocks of different diameters cannot be screened, which is not conducive to extensive promotion and popularization.
