Embodiment Construction

[0028] The core of the present invention is to provide a shearer with a reasonable distribution of the traction force of the shearer. On the basis of satisfying the demand of the shearer for large traction force, the distance between the pin-rail wheels of the shearer and the scraper conveyor is reduced. The working pressure between the pin rails also improves the stability of the shearer. Another core of the present invention is to provide a comprehensive coal mining equipment including the above coal mining machine.

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0030] Please refer to figure 2 , figure 2 It is a structural schematic diagram of a shearer placed on a scraper conveyor provided by a specific embodiment of the present invention.

[0031] In a specific embodiment, the sh...

Abstract

The invention discloses a coal mining machine which comprises at least three driving parts (26) and a traveling box, wherein the driving parts (26) are connected with the traveling box; and the pin gear of each driving part (26) is engaged with the pin rail of a scraper conveyor. The traction force distribution of the coal mining machine is reasonable. On the premise of satisfying the demands of the coal mining machine for large traction force, the working pressure between the pin gear of the coal mining machine and the pin rail of the scraper conveyor is reduced, and the stability of the coal mining machine is enhanced. The invention also discloses an integrated coal mining facility comprising the coal mining machine.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a coal mining machine. In addition, the present invention also relates to a comprehensive coal mining equipment including the above coal mining machine. Background technique [0002] my country is the main coal-producing country in the world, and the total number of coal mines exceeds the sum of the number of coal mines in all other countries in the world. At present, comprehensive mechanized coal mining has become the main method of mining coal seams. [0003] Comprehensive mechanized coal mining refers to the entire production process of the coal mining face, including coal breaking, coal loading, coal transportation, support, goaf treatment, mining roadway transportation, and excavation. The complete set of equipment for fully mechanized mining face mainly includes: shearer, scraper conveyor and hydraulic support. Shearer is coal breaking equipment for comprehe...
