Heading machine cutting head based on ultrasonic resonance

Abstract

The invention discloses a heading machine cutting head based on ultrasonic resonance. The cutting head consists of an ultrasonic transducer, an ultrasonic vibrator, telescopic cutting teeth, a roller,an ultrasonic generator, fixed cutting teeth and a frequency scanning core, wherein the ultrasonic transducer is a high-power ultrasonic transducer; the ultrasonic vibrator excites rock to vibrate and reduces the rock strength; the telescopic cutting teeth extend out by the aid of hydraulic thrust, cut into rock to cut the rock and can rotate with the ultrasonic vibrator synchronously; the fixedcutting teeth are mounted on the roller and cut the rock through rotation; the frequency scanning core scans the rock frequency in real time and feeds back the rock frequency to an operation system, and the operation system adjusts the ultrasonic frequency emitted by the ultrasonic generator in real time according to the feedback result. The cutting head has good adaptability to geological conditions, performs synchronous vibration and cutting, has controllable vibration range, high broken rock heading speed, high efficiency and long cutting tooth service life and can be applied to roadway heading in high-hardness rock strata to realize efficient breaking of hard rock.

Description

technical field [0001] The invention relates to a roadheader cutting head based on ultrasonic resonance, which is mainly used in roadway excavation, underground mining, etc., and belongs to the cross-application field of construction machinery technology and ultrasonics. Specifically, the utility model relates to a cutting head of an ultrasonic high-efficiency roadheader and a method for using the same in roadheading. Background technique [0002] The roadheader is a complete vehicle equipment that can realize the purposes of cutting, crushing, loading, and transportation at the same time. The working principle of the roadheader is: the power output by the motor is transmitted to the two-stage planetary reducer, and the power is transmitted to the cutting head through the cantilever section. The cutting touches the rock and makes it peel off. At the same time, the excavation process is realized by combining the advancement of the track of the roadheader. The mirror image cu...
