Abstract

The invention relates to a coal-rock recognition device based on cutting of a drum shearer. The coal-rock recognition device comprises a protective sleeve, a mounting bracket, a water sprayer, an ultrasonic transducer, a laser transmitter and a laser receiver; the mounting bracket is mounted in the protective sleeve; the protective sleeve is mounted on a shell of a rocker arm; and the water sprayer, the ultrasonic transducer, the laser transmitter and the laser receiver are all mounted on the mounting bracket. The coal-rock recognition device has the beneficial effects that a water flow sprayed by the water sprayer can serve as a coupling medium through the effect of ultrasonic wave receiving and transmitting of the ultrasonic transducer, a coal-rock interface is recognized according to the backward wave characteristic, and the coal-rock interface can be recognized according to the laser characteristic through laser transmitting of the laser transmitter and laser receiving of the laser receiver so that the coal-rock interface recognized through the backward wave characteristic and the coal-rock interface recognized through the laser characteristic can be compared, the recognition ability of the drum shearer over the coal-rock interface is improved, and thus cutting operation of the drum shearer is facilitated.

Description

technical field [0001] The invention belongs to the technical field of coal mining engineering, and specifically provides a coal rock identification device based on cutting by a drum shearer. Background technique [0002] The drum shearer is a complex mechanical equipment for coal mining that integrates mechanical systems and electrical systems. The use of mechanized coal mining can reduce physical labor and improve safety, so as to achieve high output, high efficiency and low consumption. . When the drum shearer is cutting coal, the identification of coal rocks is the key to realize the automation of coal mining. There are many existing coal rock identification methods, such as the sensor method based on the natural γ-ray radiation characteristics of coal rocks, the drum based The coal-rock interface recognition sensor method and the coal seam interface infrared detection method, which respond to the shearer's cutting force, have not been well applied due to immature techn...
