Abstract

The invention discloses a fully-mechanized excavator for mining, which comprises a support frame and a plurality of hanger mechanisms. The hanger mechanism includes a U-shaped fixed frame, two movable blocks, two movable frames, three strings of supporting rollers and two transverse Shifting device, three strings of rollers are sequentially arranged between the movable block and the movable frame, between two movable frames and between the movable frame and the movable block through the roller shaft. The invention changes the heights and inclination angles of the three strings of rollers by moving the traversing device, and changes the angle of the equipment according to different transport volumes, increases the practicability and durability of the equipment, and reduces maintenance costs.

Description

technical field [0001] The invention relates to a fully mechanized excavator for mining. Background technique [0002] Fully mechanized excavator, short for comprehensive mechanized roadheader, is a comprehensive mechanized equipment that integrates multiple functions of excavation, rock loading, coal transportation, even support, and nailing. [0003] The tail end of the fully mechanized excavator is provided with a conveyor belt for conveying the excavated materials. The conveyor belt is arranged on a belt frame, and the belt is supported by a plurality of three-string rollers arranged on the belt frame. [0004] Each roller of the three strings of rollers on the existing belt frame can only rotate, and cannot adjust the height and angle. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a fully mechanized excavator for mining with adjustable conveyor belt position. [0006] In order to solve the above problems...
