Abstract

The invention discloses a coal cutting visualization device of a coal mining machine. The device comprises a protection shell, a protection window frame and two camera components, wherein each camera component is provided with a water pipe bracket and a water pipe arranged on the water pipe bracket; the camera component comprises a mine camera and a camera shield sleeved on the outer part of the mine camera; a second rotation frame is arranged at the top of the camera shield; the side surface of the second rotation frame is connected with a first rotation frame through a bolt; a mine LED (light emitting diode) lamp is fixed on the side surface of the camera shield; by adjusting the angle of the mine camera, the mine camera in one camera component can observe the roller top at a cutting part of the coal mining machine, and the mine camera of the other camera component can observe the roller bottom at the cutting part of the coal mining machine; the angle of the miner camera can be adjusted at will for observation without influencing the work of the coal mining machine or the transportation of the coal; the coal cutting conditions by the roller at the cutting part of the coal mining machine can be clearly observed; the roller is effectively prevented from cutting a top plate and a bottom plate of the coal layer; and the coal cutting visualization device has a simple and compact structure, a small volume and high reliability and is easy to assemble and disassemble.

Description

technical field [0001] The invention relates to a coal cutting visualization device of a shearer, in particular to a device suitable for remotely observing the coal cutting status of a cutting part of the shearer and distinguishing coal rocks. technical background [0002] With the continuous improvement of coal mine safety production requirements, the safety of personnel and equipment in the underground mining face has been highly valued by the society. Among the many safeguard measures, unmanned coal mining technology has received extensive attention, and remote monitoring of the coal mining process is one of the key technologies to realize unmanned coal mining. The environment of the underground working face is harsh, the dust is relatively large, and the movement of the shearer and the change of the inclination angle of the rocker arm have a great impact on the monitoring effect of the coal cutting status of the shearer; The situation happens from time to time, w...
