[0002] At present, coal mines mostly use comprehensive coal mining units, which are only suitable for large-scale coal mines, and the coal reserves of thin coal seams account for 20% of the total coal reserves in my country. The coal mining technology for thin coal seams is still very backward, and the equipment efficiency is very low. Some even Mining by artificial blasting is labor-intensive, and production is not safe, and cannot meet the needs of production

Embodiment Construction
[0010] Refer to attached figure 1 , 2 The walking part of the planing trackless shearer includes two track driving wheels 3 and track driven wheels 8, the driving wheels 3 and the driven wheels 8 are connected with track chains 7 to form track sprockets, and the dust cover 2 is fixed on it. On the dust cover 2, a drive motor 14 is fixed in the middle of the two sets of crawler sprockets, and the drive motor 14 is connected to the travel part reducer 12 on the shaft. An electric control box 13 is installed in parallel with the drive motor 14, and one is fixed on the upper end of the electric control box 13. Miner's lamp 1, walking portion speed reducer 12 is equipped with steering handle 10, brake handle 11 and miner's lamp 20,21, and miner's lamp 1,20,21 is used for the illumination of walking front and back direction and coal mining wall respectively, and operation turns to handle 10 can Change the walking direction of the shearer to realize forward and reverse planing of co...

Abstract
The invention belongs to coal mining machinery, in particular to a planing trackless coal mining machine, which mainly consists of a driving motor (14), an electric control box (13), a traveling part reducer (12), a water tank (17), a water pump (18 ), cable retractable shaft (19), miner's lamp (1), (20), (21), crawler drive wheel (3), crawler driven wheel (8), dust cover (2), and the fuselage on the crawler A planer head fixing bolt (15) is installed on the upper side, a top planer (6) with two-way planer blades is fixedly installed on the upper end of the palm plate (26), and several rows of symmetrical waist knives (9) and rotary knife rests (23) are installed in the middle. ), bottom knives (5) and limit blocks (4) are installed symmetrically on both sides of the lower end, an isosceles triangle rotation control hole (27) is provided on the palm plate, and a pre-planing knife (24) is installed in the middle of the front end of the palm plate (26) , fixed limit blocks (25) on both sides, high production efficiency, simple structure, easy maintenance, and lower price than existing shearers.
Description
technical field [0001] The invention belongs to coal mining machinery, in particular to a planing type trackless coal mining machine. Background technique [0002] At present, coal mines mostly use comprehensive coal mining units, which are only suitable for large-scale coal mines, and the coal reserves of thin coal seams account for 20% of the total coal reserves in my country. The coal mining technology for thin coal seams is still very backward, and the equipment efficiency is very low, and some even Exploitation with artificial blasting is labor-intensive, and production is not safe, which cannot meet the needs of production. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a planing type trackless coal mining machine suitable for mining coal in thin coal seams, simple in structure and easy to use. [0004] The technical solution adopted by the present invention to solve the t...
