Embodiment 1

[0033] Such as figure 1 , figure 2 The shown embodiment 1 discloses a chain coal cutter, including a traction part 1, a motor part 2, and a coal cutting part; the traction part 1 is connected to the box body 11, and the motor part 2 and the transmission part 3 are located In the box body 11, the motor part 2 is connected and drives the coal cutting part through the transmission part 3; the box body 11 has a T-shaped structure, and the coal cutting part is arranged outside the box body 11, on both sides of the T-shaped protruding part, and is distributed in a symmetrical structure .

[0034] The coal cutting part is used for cutting the coal seam 10 below the box body 11 . In this embodiment, the transmission part 3 has a sprocket shaft 4, and the two ends of the sprocket shaft 4 pass through the two ends of the T-shaped protrusion of the box body 11. The transmission part 3 drives the sprocket shaft 4 to rotate through the motor part 2, and the transmission part 3 Output a...

Embodiment 2

[0042] This embodiment discloses a chain coal cutter, which includes a traction part 1, a motor part 2, and a coal cutting part. The difference between this embodiment and embodiment 1 is:

[0043]Two sprockets 5 are arranged symmetrically on the sprocket shaft 4 , that is, there is one sprocket 5 on each side of the T-shaped protrusion of the box body 11 . The position of the sprocket 5 is fixed by setting the sleeve 41 between the sprocket 5 and the T-shaped protrusion of the box body 11; the outermost end of the sprocket shaft 4 has an end cover 9, and the sprocket 5 and the sleeve 41 are installed and covered. The end cap 9 fixes the positions of the two sprockets 5 . It is also possible to change the distance between the pre-prepared sprockets according to actual needs by replacing the sleeve 41 or adjusting the length of the sleeve, so that the cutting effect of the coal cutter meets the predetermined coal mining effect of a specific coal seam.

[0044] The chain plate...

Abstract

The invention discloses a chain coal cutter, and belongs to the technical field of coal mine machines. The chain coal cutter comprises a traction portion, a motor portion and a coal cutting portion. The traction portion is connected with the motor portion, and the motor portion is connected with and drives the coal cutting portion through a transmission portion. The motor portion and the transmission portion are located in a box body, and the coal cutting portion is arranged outside the box body and is used for cutting a coal bed below the box body. The coal cutting portion is provided with a plurality of chains, and the upper ends of the chains are arranged on chain wheels in a sleeved mode. The chain coal cutter has the advantages of being large in coal cutting area, high in coal cutting efficiency and high in adaptability, saving energy, being environmentally friendly and low in manufacturing cost and the like. The cutting portion works on the coal bed below a coal cutter body, and the prostrating mining function of the chain coal cutter is achieved.

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery in coal mines, in particular to a chain coal cutter. technical background [0002] The equipment level of coal mining machinery is one of the important symbols of the technical level of coal mines. The selection of coal mining machinery depends on the occurrence conditions of the coal seam. [0003] The storage of steep coal seams in my country accounts for about 14.05% of the total coal storage. These coal seams are mainly distributed in Sichuan, Xinjiang, Guangdong, Fujian, Gansu, Inner Mongolia and Northeast China. The annual output of steep coal seams It accounts for about 8% to 10% of the total coal production in the country, but in some provinces (regions) the production of high-inclination coal seams accounts for a large proportion. For example, in Sichuan Province, 40% to 50% of coal production comes from steep-inclination coal seams. . At present, the mechanized mining equi...
