Abstract

The invention provides a movable pushing device used for a coal mining machine. The movable pushing device comprises a movable pushing seat and a guide device, wherein the guide device is fixed on a body of the coal mining machine, the movable pushing seat is installed on the guide device, sliding teeth of the movable pushing seat are matched with sliding chutes of the guide device, clamping teeth of a body of the movable pushing seat are matched with clamping grooves of the guide device, one end of a height adjustment cylinder is connected with a movable pushing seat through a gland of the height adjustment cylinder, the other end of the height adjustment cylinder is hinged with a pushing cylinder, one end of the pushing cylinder is hinged with the movable pushing seat, and the other end of the pushing cylinder is hinged on a hydraulic support. The invention further provides the coal mining machine equipped with the movable pushing device. According to the technical scheme of the movable pushing device and the coal mining machine, the movable pushing seat can move along the guide device and be stopped when moving to a required position, therefore the requirement of safe support after the change of the width of working faces can be satisfied, and the safety is improved.
