Abstract
The utility model discloses a supporting and balancing device of a low seam coal-mining machine, which comprises a coal-mining machine body, a rear supporting skid shoe, a conveyor shovel plate, a conveyor, a coal-mining machine gap bridge, a conveyor baffle ledge, a conveyor guide block, a conveyor connecting lug, a connecting pin, a push rod connecting head, a push rod, a hydraulic bracket base, an upright post, a top beam and a base gap bridge. A jack which is arranged on the push rod is fixedly connected on the base gap bridge of the hydraulic bracket base, and the push rod connecting head which is connected with the conveyor is arranged at the front end of the push rod. As the push rod is pressed by the jack after a front supporting skid shoe at the coal wall side of the coal-mining machine body is cancelled, the coal-mining machine cannot be inclined downwards, so as to be beneficial for controlling the coal-mining height of a coal-mining working surface, and avoid the front supporting skid shoe of the coal-mining machine from being easily damaged due to being affected by a component force for a long term when the coal-mining machine is in walking. Due to low seam on the working surface, the front supporting skid shoe is difficult for replacement and maintenance after being damaged.
