Abstract

The invention discloses a comprehensive coal milling device for a coal mine. The comprehensive coal milling device comprises a machine body. A cutting arm is arranged on one side of the machine body,the end part of the cutting arm is rotatably connected to a cutting roller, a base is arranged on the lower portion of the machine body, and a first dust lowering mechanism for spraying water to a coal seam on a working face and a second dust lowering mechanism for lowering dust in air on the working face are arranged on the body. By spraying the water to the coal seam through the first dust lowering mechanism, coal dust generated by coal mining is reduced. The coal dust content in the air is further reduced by purifying the air on the working face by means of the second dust lowering mechanism, so that the physical health of coal mine workers is guaranteed. Meanwhile, a shock absorbing structure is arranged at the bottom of the device to absorb shock well in the coal milling process, so that parts in the device are prevented from being damaged by vibration, and the service life of the whole device is prolonged. The device is simple in integral structure and good in dust lowering effect.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a comprehensive coal mining device for coal mines. Background technique [0002] In the mining of coal mines, the shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. However, coal mining machines will produce a large amount of coal dust during the coal mining process, which has caused serious damage to the health of coal miners. Great harm. Contents of the invention [0003] The purpose of the present invention is to provide a comprehensive coal mining device for coal mines in order to solve the above-mentioned deficiencies in the prior art, through the first dust reduction mechanism and the second dust reduction mechanism to reduce the coal dust content in the coal mining fa...
