Abstract

The invention relates to a hauling device for a thin seam shearer, in particular to a hauling part for a chain hauled shearer. The hauling part includes a head hauling part and a tail hauling part that are respectively mounted on a head rack and a tail rack of a scraper conveyer. The head hauling part and the tail hauling part both include a hauling motor, the hauling motor is connected to a decelerator fixed in a shroud through a shaft coupling, the decelerator is in connection with a chain wheel through a pin coupling, and a hauling chain positioned in a scraper conveyer chain channel is twined on the chain wheel. The hauling part provided by the invention is installed on the head rack and the tail rack of the scraper conveyer, and the part riding right over the scraper conveyer is only a hauling part omitted shear frame, thus reducing the thickness of the shearer on the scraper conveyer, and ensuring the coal space of the shearer. The hauling part for the chain hauled shearer provided by the invention solves the defects of high machine surface height, narrow and small coal space, complex structure and poor adaptability of existing thin seam electrically hauled shearers.

Description

technical field [0001] The invention relates to a traction device of a thin coal seam shearer, in particular to a traction part for a chain traction shearer. Background technique [0002] With the gradual reduction of coal resources, people pay more and more attention to the thin coal seam coal resources that were difficult to mine in the past. In order to develop such resources efficiently, the requirements for thin coal seam shearers are also increasing. high. First of all, the height of the thin coal seam shearer is affected by the thickness of the coal seam and is generally required to be less than 1 meter; secondly, the space for the shearer to pass through the coal should not be too narrow, and the minimum clear height of the coal pass should not be less than 0.3 meters, otherwise, The mined coal is difficult to be transported smoothly from the working face. The thickness of the scraper conveyor itself is 0.3 meters, which requires the design of the shearer frame with...
