Water drilling machine

Abstract

The invention provides a water drilling machine and relates to the field of engineering machines. The water drilling machine comprises a machine body, a drill bit, a handle and a water spraying device. A motor is arranged inside the machine body, the drill bit is arranged on the left side of the machine body, the drill bit is connected with the motor, the handle is arranged on the right side of the lower portion of the machine body, a switch is arranged on the handle, the water spraying device comprises a nozzle, an automatic on-off valve and a water pipe, the water pipe is connected with theautomatic on-off valve, the other end of the automatic on-off valve is connected with the nozzle, the nozzle is arranged above the left side of a connecting piece, the nozzle is parallel to the top ofthe drill bit, the other end of a water inlet pipe is connected with a water tank, the water tank is sealed, and a booster is arranged above the water tank. The nozzle is arranged for cooling the rotary drill bit, drilling operation can be completed through only one worker, the labor cost is reduced, a dustproof cover is arranged outside the drill bit, the dustproof cover is tightly attached to the wall face in the drilling process, dust is greatly reduced, and worker health is protected.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a hand-held water drilling machine. Background technique [0002] The water drilling rig is a kind of drilling equipment, which is used to drill holes on the outer wall of the building for air conditioners, smokers and other equipment. The general method of use is to attach the drill bit of the water drilling rig to the wall where the hole needs to be drilled, and then rotate the drill bit. The drill bit slowly enters the wall, and finally the drill bit passes through the wall, leaving a hole in the wall for other equipment. During the drilling process, water needs to be added to the drill bit. The drill bit cools down, and the second is to make the water absorb the dust generated during the drill bit rotation. Existing water drilling rigs are generally hand-held, aiming at the wall to drill holes, and another worker is required to add water to the rotating drill bit to cool...

AI Technical Summary

Problems solved by technology

Existing water drilling rigs are generally hand-held, aiming at the wall to drill holes, and another worker is required to add water to the rotating drill bit to cool down, which increases the number of workers and increases the cost; even if water is used to absorb dust, there will still be some Dust is generated, which is not conducive to the health of workers, and it is easy to get pneumoconiosis after working for a long time, and it is also not conducive to the cleaning of dust in the later stage
