Thin seam coal mining machine body

Abstract

The invention relates to a thin seam coal mining machine body. The thin seam coal mining machine body comprises a machine body shell, traction systems and an electric control system, wherein the traction systems and the electric control system are arranged in the machine body shell, the electric control system is arranged in the middle, the two traction systems are arranged on the left side and the right side of the electric control system correspondingly, and the electric control system and the two traction systems are independent from one another in respective space; large-and-medium, medium-and-small and small parts of the traction systems are mainly arranged on the front portion, the middle portion and the rear portion of the machine body shell correspondingly, large-and-medium electric parts of the electric control system are mainly arranged on the front portion and the middle portion of the machine body shell, and medium-and-small electric parts of the electric control system aremainly arranged on the middle portion and the rear portion of the machine body shell; and the height of the rear portion of the machine body shell is not larger than that of the middle portion, the height of the middle portion is not larger than that of the front portion, and oil cylinder connecting lugs and rocker arm connecting lugs are arranged on the front portions of the left and right sidesoutside the machine body shell. According to the thin seam coal mining machine body, a corresponding coal mining machine can more easily meet mining requirements of thin or ultra-thin coal seams withcomplex working faces under the conditions of low mining height, high coal and rock hardness and the like.

Description

technical field [0001] The invention relates to a shearer body, which is mainly designed for a low-body high-power thin coal seam shearer, so that the corresponding shearer is more suitable for the mining of thin or extremely thin coal seams in complex working faces with high hardness of coal rocks. Background technique [0002] For the mining of thin or extremely thin coal seams, the mining height is often low (some mining height reaches the required 0.8m), and the geological conditions are complex (such as coal and rock coexistence, high hardness), etc., so in order to improve the adaptability and reliability of the shearer , generally require thin coal seam shearer body height is getting shorter and shorter, while the installed power is getting bigger and bigger. However, as the power increases, the size of the motor and transmission system will also increase a lot accordingly. Therefore, the structural layout of the thin or extremely thin coal seam shearer is an importan...

AI Technical Summary

Problems solved by technology

This method has been adopted in thin coal seam shearers. Although it can improve the structural layout to a certain extent, for example, it helps to increase the clearance of the machine, but at the same time it brings other outstanding problems, including being close to the coal mine. The local structure height of the shearer on one side of the wall is relatively high, the span between the left and right rollers is relatively large, the adaptability of the rollers to the mining height is poor, the height of the shearer machine under the support is high, and the coal passing space above the scraper conveyor is small, which is difficult for undulations. Poor work surface adaptability, etc.

Therefore, this scheme is still difficult to meet the mining needs of extremely thin or thin coal seams, especially the mining needs of extremely thin or thin coal seams with complex conditions such as low mining height and high coal rock hardness.
