Abstract

The invention relates to the field of coal mine underground fully-mechanized face mining and conveying and particularly provides a middle groove for an automatic towing cable chain traction coal mining machine and a scraper conveyer. The middle groove comprises a main groove body, a sliding rack cover, a towing cable upper chain cover, cable groove cover plates and detachable cable grooves, wherein the towing cable upper chain cover and the main groove body are connected together adopting bolts to form a towing cable upper chain way in a semi-enclosed state, and the towing cable upper chain way and a towing cable lower chain way are of an up and down arrangement structure in the vertical direction. The middle groove is suitable for thin-coal-seam chain traction coal mining machines and integrates coal conveying, coal mining machine traction guiding and coal mining machine cable towing guiding into a whole, two chain ways of an automatic towing cable system are vertically arranged on the outer side of a coal mining machine power supply cable groove, a chain is made to be engaged with a driving chain wheel better to be not prone to generating chain off, and the middle groove for theautomatic towing cable chain traction coal mining machine and the scraper conveyer are also more convenient to maintain.

Description

technical field [0001] The invention relates to the mining and conveying field of fully mechanized mining working faces in underground coal mines, in particular to a middle groove and a scraper conveyor used for an automatic towline chain traction coal shearer. Background technique [0002] In thin coal seams and extremely thin coal seams, shearers using chain traction are more and more favored by users because of their small body height and high cutting power. In the limited coal mining space of the thin coal seam, affected by the coal mining process, the scraper conveyor on the working face must have the automatic cable towing function of the coal mining machine cable, so that the complete set of coal mining equipment will develop towards automation and intelligence, and reduce labor costs. Operating time, improve coal mining efficiency and safety. At present, there is a scraper conveyor that can be used in conjunction with a chain traction shearer (authorized announcemen...
