Dust-free and mud-free water drilling machine

Abstract

The invention belongs to the technical field of water drilling machines, and particularly relates to a dust-free and mud-free water drilling machine. The dust-free and mud-free water drilling machine comprises a motor, an adjusting transmission mechanism, a fixing sleeve, a sealing module, a first drill bit, a second drill bit and a third drill bit. According to the dust-free and mud-free water drilling machine, before punching, a shallow hole larger than the outer diameter is firstly drilled out in the wall surface through the first drill bit, when the second drill bit is used for punching, the conical surface of a sealing rubber ring in a sealing module is inserted into the punched shallow hole, and the rubber sealing ring plays a sealing role between the second drill bit extending into a cavity and the wall surface; and the situation that in the water cooling process, slurry is brought out by cooling water and flows down from the lower side of the hole in a wall attaching mode, or in the punching process, the slurry is splashed to the periphery of the hole, and inconvenience is brought to follow-up cleaning of punching is avoided.

Description

technical field [0001] The invention belongs to the technical field of water drilling machines, in particular to a dust-free and mud-free water drilling machine. Background technique [0002] At present, in industrial or civil buildings, water drilling rigs are often used for drilling operations during the installation of pipelines and equipment. The water drilling rig is a general-purpose wall drilling machine, which consists of a motor, a transmission and a water drill. [0003] In the process of drilling a wall hole with a water drill, especially when the wall is relatively thick, it is necessary to inject water to cool it during the process of drilling through the wall, otherwise it will cause the drill bit to overheat and damage the drill bit. During the water cooling process, the water will rush down the drill hole The mud is brought out from the side and flows down from the lower side of the hole against the wall.

[0003] In the process of drilling a wall hole with a water drill, especially when the wall is relatively thick, it is necessary to inject water to cool it during the process of drilling through the wall, otherwise it will cause the drill bit to overheat and damage the drill bit. During the water cooling process, the water will rush down the drill hole The mud is brought out from the side and flows down from the lower side of the hole against the wall. On the other hand, under the rotating drill bit, part of the mud is splashed around the hole. After the drilling is completed, the cleaning of the wall is not easy to clean, especially for Lime white walls are difficult to clean. The existing technology is to add a splash guard at the drilled hole. When the wall is flat, it can prevent the mud from sticking to the wall. However, for uneven walls or tiles There will still be some mud flowing out of the groove at the place; and this method will cover the relative position of the drill bit and the borehole, affecting the operator's operation
