Semi-suspended thin seam mining machine traction part with crushing device

Abstract

The invention relates to a semi-suspension type thin seam mining machine traction part with a crushing device, which comprises a traction part shell, a traction motor, a traction part planetary reducer and the crushing device, and the traction motor and the traction part planetary reducer are arranged at the front part in the traction part shell side by side; an output shaft of the traction motor is connected with the input end of the traction part planetary reducer through a gear transmission mechanism, the output end of the traction part planetary reducer is in coaxial transmission connection with a transmission shaft, and most of the transmission shaft and the gear transmission mechanism are located on the rear portion in the traction part shell. And the crushing device is mounted on the outer side wall of the rear part of the traction part shell in the positive traction direction. By changing the structural form of the traction part and installing the crushing device, the problem of coal blockage between the body of the coal mining machine and the chute of the scraper conveyor is solved.

Description

technical field [0001] The invention relates to a traction part of a thin coal seam shearer, which adopts a semi-suspended arrangement type and is used to solve the problem of small coal passing space. Background technique [0002] The thin coal seam shearer has a short fuselage and a small space for passing coal. Large lumps of coal or gangue are easily blocked between the fuselage and the chute of the scraper, resulting in coal blocking, which causes the shearer to be overloaded and needs to be shut down for processing. Affect the working efficiency of the shearer. SUMMARY OF THE INVENTION [0003] The invention aims to provide a traction part of a semi-suspended thin coal seam shearer with a crushing device, which can solve the problem of coal blocking between the body of the shearer and the chute of the scraper by changing the structure of the traction part and installing the crushing device . [0004] The main technical solutions of the present invention include: ...
