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

Abstract

The invention discloses a device and a method for monitoring and identifying coal rock for a coal cutter in real time, and is suitable for use in the coal mining process of a coal drill-type coal cutter. The device is composed of four vibration sensors, a current sensor, a single chip, an alarm circuit, a display and an output circuit. The monitoring and identifying method comprises the steps of: evenly distributing the four vibration sensors around a drill clamp of the coal cutter, detecting the current of a driving motor of a drill of the coal cutter by the current sensor; judging whether a drill stem is contacted with the coal rock by increasing the driving current of the drill motor; and judging the position of the drill contacted with the coal rock by using the vibration sensors distributed around the drill clamp, and providing information for control on the drill stem, so as to achieve the intelligent control on the drill-type coal cutter. The device is simple in structure, convenient to operate and good in using effect.

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.
