Abstract

The invention discloses a coal shearer and its cutting part transmission structure, wherein, the cutting part transmission structure of the coal shearer comprises: a cutting motor, a gear transmission part and a drum, and the cutting motor passes through the gear The transmission part is connected with the drum, and the cutting motor is installed on the traction part of the shearer. In the transmission structure of the cutting part of the shearer provided by the present invention, the cutting motor does not swing with the rocker arm, which does not affect the coal passing space of the scraper machine. The shortened rocker arm can shorten the center distance between the two drums of the shearer and facilitate the operation of the lifting equipment. stability.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a coal shearer and a transmission structure of a cutting part thereof. Background technique [0002] Under thin coal seam mining conditions, the coal has high hardness, gangue, faults and other geological structures are common, the thickness of the coal seam varies greatly, the fluctuation changes greatly, the labor intensity of the workers is high, the operation and maintenance are difficult, and the coal loading effect is not good. Therefore, for thin coal seam working conditions, it is required that the coal shearer must have sufficient cutting power and traction power in a limited space, and at the same time, the layout of the whole machine should be compact, the height of the fuselage should be low, and the scraper must be guaranteed There is enough coal passing space between the transport and the shearer to ensure the transport capacity of the scraper conveyor.
