Coal mine crushing device

Abstract

The invention relates to mine machinery, in particular to a coal mine crushing device. The technical problem to be solved by the invention is to provide the coal mine crushing device capable of thoroughly crushing coal mines. The coal mine crushing device comprises a main body; a feed port is formed above the main body; a discharge port is formed below the main body; the main body includes a crushing bin and a grinding bin; the crushing bin is arranged above the main body; the grinding bin is arranged at the lower part of the crushing bin; a rotating shaft is arranged in the crushing bin; a crushing roller is mounted on the rotating shaft; a broken tile crushing cutter is mounted on the crushing roller; a screen plate is arranged between the crushing bin and the grinding bin; and through holes are formed in the screen plate. The coal mine crushing device further comprises tooth roller grinding devices symmetrically arranged in the grinding bin. In the coal mine crushing device, the coal mines are primarily crushed by the effect of the crushing roller in the crushing bin, and are grinded again by the effect of the tooth roller grinding devices in the grinding bin, so that the coal mine crushing effect is greatly improved, the coal mine crushing degree is higher, and the coal mine crushing is more thorough.

Description

technical field [0001] The invention relates to a mining machine, in particular to a coal mine crushing device. Background technique [0002] At present, the coal mining industry drives the economic development of a part of the society and plays an important role in production and life. However, coal mining, processing and transportation are an important production industry chain. Coal mines are often very large when they are mined, and they are very inconvenient to transport and use. Therefore, coal mines need to be crushed, and there are various types of coal mine machinery, among which coal mine crushing devices are indispensable for coal mining equipment. The existing coal mine crushing devices have a simple structure, a single crushing method, coal mine crushing is not thorough, and the crushing effect is poor.
