Two-arm and four-roller coal mining machine

Abstract

The invention discloses a two-arm and four-roller coal mining machine, and belongs to the technical field of coal mine machines. The two-arm and four-roller coal mining machine comprises a traction part, a motor, a drive part, rocker arms and a height-regulating device. The motor is connected with the drive part and used for supplying power to the two-arm and four-roller coal mining machine. The drive part is connected with the two rocker arms, namely the first rocker arm and the second rocker arm, and each rocker arm is connected with two sets of rollers. The traction part is connected with traction equipment and used for driving the entire two-arm and four-roller coal mining machine to move. Due to the fact that the two-arm and four-roller coal mining machine is provided with four rollers, the coal mining area is greatly increased, and the sizes of the rollers can be changed according to actual needs. A worm and gear device is used for regulating the coal mining height, so that energy saving and environmental protection are achieved. According to the coal mining machine, the left-right vacillating coal mining height can be regulated according to actual terrain, and thus the adaptability of the coal mining machine is enhanced. The two-arm and four-roller coal mining machine has the advantages of being large in coal mining area, high in coal mining efficiency, adjustable in coal mining height, high in adaptability, saving in energy and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery in coal mines, in particular to a double-arm four-drum shearer suitable for steeply inclined coal seams. 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 c...

AI Technical Summary

Problems solved by technology

At present, the mechanized mining equipment for steeply inclined coal seams in my country cannot meet the needs of our country. Therefore, it is very necessary to develop a shearer with strong adaptability, high yield and high efficiency to meet the needs of coal mining in our country.
