1. The impactor of a down-the-hole drilling rig is a key component of down-the-hole drilling rig drilling. It is used to provide axial reciprocating rock-breaking impact force to the drill bit in order to cool the drill bit and entrain cuttings.
2. It is also the power fluid for downhole power drilling tools. The structure is shown in the figure below, which mainly consists of rear joint, outer sleeve, check valve, air regulating plug, cylinder, valve seat, piston, guide sleeve, disc spring, snap ring, spring, retaining ring, rubber ring, front Connectors, etc.
Performance characteristics of down-the-hole drilling rig impactors:
1. The contemporary new rock drilling theory is used to design the internal structural dimensions of the impactor, so that the impactor can obtain ideal energy transfer, with large single impact power and fast rock drilling speed.
2. Unique taper diameter reduction design. If gravel and soil are stuck during drilling,the taper diameter reduction can reduce the lifting resistance when the drill rig is lifted up, greatly reducing the failure of the impactor to be lifted out.
