1. The internal structure and size of the impactor are designed using the contemporary new rock drilling theory,
so that the impactor can obtain ideal energy transfer, large single impact power and fast rock drilling speed.
2. In order to prevent dust pollution during perforation and rock drilling operations, the main components
of the product also use a special computer-controlled heat treatment process to facilitate the addition
of a small amount of high-pressure water to the compressed air for wet rock drilling to protect the health of the operator.
3. This design allows users to directly connect to the drill rod without a reducer, reducing user production costs.
The impactor of a down-the-hole drill is a key component of the drilling process of a down-the-hole drill.
It is used to provide axial reciprocating rock-breaking impact force to the drill bit in order to cool the drill bit and carry rock cuttings, etc.
It is also the power fluid of the bottom hole power drill tool.
Working principle of the impactor of a down-the-hole drill:
The compressed gas enters the impactor through the drill pipe and is then discharged from the drill bit. The discharged exhaust gas is used to remove the rock.
The rotary motion of the impactor is provided by the rotary head, and the axial thrust is provided by the propeller,
which is transmitted to the impactor through the drill rod. The drill sleeve is mainly used to transmit propulsion force and rotary motion to the drill bit.
The retaining ring controls the axial movement of the drill bit, and the check valve is used to prevent debris such as rock chips from entering
the impactor when the compressed air supply is stopped. During the drilling process, the drill bit is pushed into the impactor and pressed on the drill sleeve.
At this time, the piston directly impacts the drill bit for rock drilling. When the drill bit is lifted off the bottom of the hole, strong blowing begins.
