Problems solved by technology

[0005] The above-mentioned type of rotary drilling rig connects the impact barrel drill to the rotary drilling rig through the connecting party, and after the pipeline is connected, it enters the rock formation at the bottom of the hole. The drilling rig drives the impactor to rotate to realize continuous drilling deep into the rock layer, but the overall structure of this type of percussion barrel drill is complex, and the structural layout is unreasonable, the overall gas pipeline is easily damaged, and it is difficult to repair

Abstract

The invention discloses an annular cluster-type down-hole hammer. The annular cluster-type down-hole hammer comprises a down-hole hammer body; a cylindrical cavity is formed in the down-hole hammer body; a plurality of crushing hammer heads are arranged on the lower end surface of the down-hole hammer body; an impactor hammer for driving the crushing hammer heads to impact a rock layer is arrangedin the down-hole hammer body; and a storage device for collecting and storing crushed stone powder is arranged on the down-hole hammer body. The rock layer is crushed by using an impacting and crushing principle of the impactor hammer, so that the operation efficiency can be improved, and the energy consumption is reduced; and the crushing of a rock layer with a large-diameter pile hole can be realized, the overall work is pollution-free, slag is discharged directly with high-pressure exhaust gas discharged by the impactor hammer, the vibration of the hammer body is small, a drilling rig device and a hole wall are not damaged, and the hole forming quality is high.

Description

technical field [0001] The present invention relates to a down-the-hole hammer, specifically, an annular cluster type down-the-hole hammer with simple structure, convenient use, high operating efficiency, low energy consumption, no pollution, small vibration of the hammer body, and high hole-forming quality. The utility model belongs to the technical field of drilling machinery. Background technique [0002] Rotary drilling rig is a common large-scale pile driver, which can quickly drill into rock and soil layers. It is mainly used in the construction of large pile holes. Generally, large-diameter pile holes are driven by rotary drilling rigs in hard rock environments. Wheel barrel drill for work. The barrel drilling operation method is to apply pressure to the barrel drill through the drilling rig, use the alloy cone on the barrel drill to roll and break the rock formation, and then cut out the ring groove, and use the mud circulation method to discharge the slag, and then...
