Device and method for monitoring and identifying coal rock for coal cutter in real time

Abstract

Disclosed are an apparatus and a method for real-time coal surveying and identification for a shearer, suitable for use in the coal cutting process of a coal drill-type shearer. The apparatus is composed of vibration sensors (1), an electric current sensor (2), a single-chip machine (4), a warning circuit (5), a display (6) and an output circuit (7). The method for surveying and identification involves arranging four vibration sensors (1) evenly around a shearer drill clamp, detecting by the electric current sensor the electric current of a driving motor of a drill bit of the shearer, judging whether or not a drill rod has contacted coal by an increase in the driving electric current of the drill motor, judging the position of the drill bit contacting the coal by means of the vibration sensors distributed around the drill clamp, providing information to control the drill rod, and achieving intelligent control of the drill-type shearer. The apparatus has a simple structure, is convenient to operate, and has good usage effects.

Description

technical field [0001] The invention relates to a real-time monitoring and identification method and device for coal rocks of a coal mining machine, and is especially suitable for the real-time monitoring and identification device and method for coal rocks of a coal mining machine used in the coal mining process of a coal mining drill type coal mining machine. Background technique [0002] Drilling shearer is currently a new type of coal mining machine to adapt to thin coal seam mining. In drilling coal mining, when the drill pipe encounters hard coal rock, it will deviate from the drill, which will not only easily damage the drill pipe, but also affect the depth of coal drilling. Corrective control is often required at this time. The current method is to rely on the miner’s vision to judge the situation where the drill pipe hits the coal rock. When the miner finds that the drill pipe has drilled into the coal rock and deviated, the drill pipe has already deviated and it wil...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a real-time monitoring and identification device and method for coal and rock of a shearer with simple structure and convenient operation, aiming at the fact that the coal mining machine in the traditional planing mode cannot automatically carry out coal and rock identification.
