Embodiment Construction

[0044] The invention discloses a height-adjustable cutting system with internal power, such as Figure 1-16 As shown, it includes a non-oscillating transmission part 1, a motorless rocker arm 2, a cutting motor, a hydraulic system 4 and an oil cylinder 3. The non-oscillating transmission part includes a static housing 11 and a front-stage transmission system arranged in the static housing. The motorless rocker arm is equivalent to a swing transmission part, including a rocker arm housing 21 and a rear stage transmission system arranged in the rocker arm housing. A motor installation cavity and a rocker arm installation cavity 114 are arranged in the static housing, the cutting motor is fixedly installed in the motor installation cavity, and the root of the cylindrical structure of the rocker arm housing is rotatably supported on the The rocker arm is installed in the cavity so that the rocker arm housing can swing with a fixed axis relative to the static housing, wherein the ...

Abstract

The invention relates to a height-adjustable cutting system with internal power. The height-adjustable cutting system comprises a non-swinging transmission part and a motor-free rocker arm, wherein the non-swinging transmission part comprises a standing shell and a preceding-stage transmission system, the motor-free rocker arm comprises a rocker arm shell and a post-stage transmission system, a cutting motor is installed in the standing shell, the base of the rocker arm shell is rotatably supported in the standing shell, an output shaft of the cutting motor is linked to the post-stage transmission system through the preceding-stage transmission system, a large gear and a planetary mechanism which are coaxially connected with an input end of the post-stage transmission system are arranged in a base cavity of the rocker arm shell, the two ends of an oil cylinder are hinged to the rocker arm shell and the standing shell respectively, a hydraulic system of the oil cylinder is installed inan oil tank of the standing shell, and one transmission shaft in the preceding-stage transmission system replaces a hydraulic system pump motor to provide power for the hydraulic system. By means of the height-adjustable cutting system, the problems in configuration of the structure of a hydraulic system pump case of a short-body large-power thin coal seam shearer for a coal rock working face witha low exploiting height and a complicated geological condition can be solved.

Description

technical field [0001] The invention relates to a cutting system of a coal shearer, in particular to a hydraulic system pump box built in, which is suitable for the cutting system of a low body and thin coal seam coal shearer with a low mining height and complex working conditions. Background technique [0002] For the mining of thin or extremely thin coal seams, the mining height is often low (some mining height requirements reach 0.8m), and the geological conditions are complex, such as coal and rock coexistence, etc. Therefore, in order to improve the reliability of the shearer, the thin coal seam shearer installed Power requirements are increasing to increase their adaptability. However, as the power increases, the size of the motor and transmission system also increases a lot. However, when thin coal seams are mined, the space of the coal mining face is usually narrow. If the overall size of the shearer is too large, the peripheral space of the shearer will be compress...
