Becoming standing wave resonance, horn, by after the Amplitude amplification of output, is applied directly on the pick of drill bit, pick
Impact grinding rock.When rock is resonated, inside can quickly produce damage, and the intensity of rock can be significantly
Degree drastically declines.Ultrasonic vibrator is connected on the fluted disc of churning driven head by this utility model first.
During this bit operation, the ultrasonic activation that ultrasonic vibrator produces is by horn shaking output
Width amplify after, be applied directly on the pick of drill bit, pick impact rock so that the transmission of ultrasound wave away from
From minimizing, the energy loss reduced in propagating on the way of maximum.Thus damage hole rapidly and efficiently
Bed rock stone so that it is intensity rapid decrease.Owing to rock strength reduces, the abrasion of drill bit reduces, and extends
In the life-span of drill bit, improve drilling efficiency.Thus realize ultrasonic activation auxiliary rotary drilling.
The beneficial effects of the utility model:
1, ultrasonic vibrator is connected on the fluted disc of churning driven head by this utility model, and carries out with pick
Connect, overcome churning driven head and creep into the technical problem that hard rock exists.This utility model can be at drill bit
Directly produce ultrasonic activation on pick, be not required to transmit through drilling rod, substantially increase Energy harvesting
Rate；
2, this utility model applies supersonic frequency alternating voltage on ultrasonic vibrator, and input voltage frequency sets
Being set to the operating frequency of ultrasonic vibrator, piezoceramic material selected by this ultrasonic vibrator, utilizes pressure
The inverse piezoelectric effect of electroceramics, converts electric energy to mechanical energy, is formed and stay in whole ultrasonic vibrator
Ripple resonates.Make rock when being resonated, quickly produce fatigue broken, improve rate of penetration.This practicality
The novel bit wear that reduces, extends bit life.
