Single-motor and double-cutting-system thin seam coal mining machine

Abstract

The invention relates to a single-motor and double-cutting-system thin seam coal mining machine. The single-motor and double-cutting-system thin seam coal mining machine comprises cutting systems, a machine body, a guiding device, a dragging connecting device and a supporting sliding shoe, wherein the roots of motor-free rocker arms of the cutting systems are rotationally supported in a standing shell of a non-swing transmission part, large-size and medium-size parts such as a single cutting motor, two sets of large gears and a planetary mechanism of the cutting systems do not have position change along with swing of the rocker arms, the standing shell is fixed to the machine body and located in front of the machine body, the two form a basic framework of the coal mining machine, the guiding device and the supporting sliding shoe are installed on the basic framework and support the rear part and the middle part of the basic framework from the lower part, and the machine body is in floating connection with a dragging chain of a scraper conveyor through the dragging connecting device. With the single-motor and double-cutting-system thin seam coal mining machine, the structural arrangement difficulty of a short-machine-body high-power thin seam coal mining machine for an ultra-thin or thin coal seam working face with the complex conditions including small mining height, high coalrock hardness and the like can be solved.

Description

technical field [0001] The invention relates to a thin coal seam shearer, which is especially suitable for the mining of extremely thin or thin coal seam working faces with complex conditions such as low mining height and high hardness of coal rock. 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. Therefore, in order to improve the reliability of the shearer, in While the body of the thin coal seam shearer is required to be short enough, the installed power is required to be larger and larger to improve its adaptability. However, as the power increases, the size of the motor and transmission system also increases correspondingly, and the space of the coal mining face is usually small when the thin coal seam is mined. If the overall size of the shearer is too large, t...
