Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] like figure 1 and figure 2 As shown, the present invention is preferably a kind of coal shearer: the two ends of the coal shearer are all provided with the traction part 3 that is used for traction coal shearer walking, and the cutting part 2 is installed on the traction part 3, and the cutting part 2 is installed There are rollers 1. A traction planetary reducer 4 and a traction motor 5 are installed in the traction part 3 . The traction motor 5 draws the shearer through the traction planetary reducer 4 (such as figure 1 shown).

[0024] like figure 1 As shown, a first cutting motor 31 and a second cutting motor 32 are installed on the traction unit 3, the first cutting motor 31 an...

Abstract

The invention discloses a coal shearer, which comprises a traction part used for traction of the coal shearer, a cutting part is installed on the traction part, a roller is installed on the cutting part, the cutting part and the traction part are rotatably connected, and the A first cutting motor and a second cutting motor are installed on the traction part, and the first cutting motor and the second cutting motor are coaxially arranged; the first cutting motor and the second cutting motor are used to drive the drum to rotate. The invention shortens the length of the rocker arm, reduces the vibration moment generated when the drum cuts coal, and improves the stability of the whole machine; avoids the blocking of the cutting motor on the coal opening when the cutting part is raised and lowered; improves the adaptability of the shearer to the undulating working face . Ensure the strong cutting ability of the whole machine to meet the needs of green and energy-saving production.

Description

technical field [0001] The invention relates to the field of coal mining machinery, in particular to a coal mining machine. Background technique [0002] Generally, the operating conditions of thin coal seam shearers are relatively harsh, and there are many problems such as faults, gangue, and large fluctuations in the working face, which makes the design starting point and structure of thin coal seam shearers very different from traditional medium-thick coal seam shearers. . [0003] At present, the thin coal seam shearer is designed to pursue the lowest machine surface height and the largest coal passing area. Due to the large volume of the existing thick coal seam shearer, the internal transmission system is complicated, and the transmission system is large in volume. [0004] For example: according to different traction requirements, the traction part reducer is usually composed of a three-stage spur gear transmission system to reduce the high speed of the AC variable ...
