The impactor is a key component in the drilling of a down-the-hole drilling rig. It is used to provide axial reciprocating crushing impact force to the drill bit to cool the bit and entrain cuttings. It is also the power fluid of the bottom hole power drilling tool. The structure is as follows As shown in the figure, it is mainly composed of rear joint, outer tube, check valve, air regulator, cylinder, valve seat, piston, guide sleeve, disc spring, snap ring, spring, retaining ring, rubber ring, front joint, etc. .


1. The internal structure size of the impactor is designed using contemporary rock drilling theories, so that the impactor can obtain the most ideal energy transfer, with large single impact power and faster rock drilling speed.
2. The unique taper diameter reduction design, if crushed stone and soil jam occurs during drilling, the taper diameter reduction when the drilling rig is raised can reduce the lifting resistance and greatly reduce the occurrence of failures that the impactor cannot lift.
3. In order to prevent dust pollution in perforated rock drilling operations, the main parts of the product also adopt a special computer program-controlled heat treatment new technology to facilitate adding a small amount of high-pressure water to the compressed air to perform wet rock drilling to protect the operator. health.
4. With this design, users can directly connect with drill pipes without reducing joints, reducing user production costs.
5. The selected raw materials and advanced processing technology have more stable performance and longer life.
6. It has the simplest and most reliable internal structure with easy assembly and disassembly, with fewer failures and convenient maintenance.
