Abstract

The invention relates to the technical field of coal mining equipment, in particular to a scraper conveying device, a double-toothed-rail scraper conveyor and a coal mining device. The scraper conveying device comprises middle grooves. The double-toothed-rail scraper conveyor comprises a machine head transmission part, a transition groove, an adjusting groove, a machine tail part and a middle groove body formed by the multiple middle grooves which are fixedly connected together. The coal mining device comprises a coal mining machine body and the double-toothed-rail scraper conveyor. The structure is reasonable and compact, by arranging toothed rails, the coal mining machine can walk on the double-toothed-rail scraper conveyor through toothed rail wheels, the phenomena that the coal miningmachine is uneven in stress, stuck and cannot walk smoothly in the working process are avoided, and installation and maintenance are also convenient; by arranging detaining grooves, the problems thatcoal cutter cutting rollers on the left side and the right side of a coal cutter body are uneven in stress, stuck and incapable of walking smoothly, the coal cutter body inclines, the coal cutter bodyjumps, and a coal cutter topples over can be solved, the failure rate of the coal cutter is decreased, and the coal cutting efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of coal mining equipment, and relates to a scraper conveying device, a double rack scraper conveyor and a coal mining device. Background technique

[0002] The traditional double rack scraper conveyor is generally one-sided rack, the other side of the scraper conveyor is equipped with a shovel, the upper side of the shearer shovel is the shearer drum, and the front of the shearer shovel is shovel. coal, this type of scraper conveyor generally has a large cross-sectional size (the cross-sectional size is generally 630mm and above), and the weight of the matching shearer is also relatively heavy. There is a cutting drum on one side, and the other side of the shearer is a walking gear mechanism that can engage with the single-side rack conveyor to travel. For the use of a single-side drum shearer with a single-side rack scraper conveyor, the force is generally not There will be problems of uneven force, sticki...
