Coal and rock identification device based on cutting by drum shearer

Abstract

The invention relates to a coal and rock identification device based on the cutting of a drum shearer. The coal and rock identification device includes a protective sleeve, a mounting bracket, a water sprayer, an ultrasonic transducer, a laser transmitter, and a laser receiver. In the protective sleeve, the protective sleeve is installed on the shell of the rocker arm, and the water sprayer, ultrasonic transducer, laser transmitter and laser receiver are all installed on the mounting bracket. The beneficial effects of the present invention are: through the function of transmitting and receiving ultrasonic waves of the ultrasonic transducer, the water flow ejected from the sprinkler can be used as the coupling medium, the coal-rock interface can be identified according to the echo characteristics, and the laser and laser can be emitted by the laser transmitter. The receiver receives the laser and can identify the coal-rock interface according to the laser characteristics, so that the coal-rock interface identified by the echo characteristics can be compared with the coal-rock interface identified by the laser characteristics, and the coal-rock interface of the drum shearer can be improved. Recognition ability, in order to facilitate the cutting operation of the roller shearer.

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...
