Embodiment 1

[0012] A percussion drill with a liquid spray device, such as figure 1 As shown, the hammer drill housing 1 is included, and the middle part of the upper end surface of the hammer drill housing 1 is provided with a mounting seat 3, and the right part of the mounting seat 3 is fixedly connected with a universal pipe nozzle 2. When the hammer drill with a liquid spraying device is working, The external infusion tube is directly inserted into the quick connector to connect with the liquid spray device, which is fast and convenient. The position of the universal tube can be adjusted according to the needs, and the liquid with pressure flows out from the nozzle and mixes with the dust in time, reducing the air pollution at the work site; The liquid plays the role of cooling and lubricating, keeps the temperature of the drill bit normal, improves the service life of the drill bit, does not need to be replaced frequently and fails; ensures normal work, improves the working environment...

Embodiment 2

[0014] The impact drill housing 1 has an internal thread in the middle of the upper end surface, and the center of the lower end surface of the mounting seat 3 has an external thread. The mounting seat 3 is threadedly connected with the middle of the upper end surface of the impact drill housing 1, and the connection is tight, detachable, easy to maintain and replace. .

[0015] The mounting seat 3 has a through hole 6 from left to right; the left part of the through hole 6 of the mounting seat 3 has an internal thread, the right end of the quick connector 5 has an external thread, and the right end of the quick connector 5 is threadedly connected with the left end of the mounting seat 3; the mounting seat 3 There is a regulating valve with a regulating handle in the middle 4, the regulating valve can adjust the flow and pressure of the input liquid in a timely manner according to the site conditions; the quick connector structure makes it easy to insert the external liquid pip...

Abstract

The invention belongs to the technical field of electronic products, and particularly provides a percussion drill with a liquid spraying device. The percussion drill comprises a percussion drill shell, a mounting seat is mounted in the middle of the upper end face of the percussion drill shell, and the right portion of the mounting seat is fixedly connected with a universal pipe nozzle, so that the problem that existing percussion drills are not provided with liquid spraying devices is solved. When the percussion drill works, an external liquid delivery pipe is directly inserted into a quick joint to be connected with the liquid spraying device, so that quickness and convenience are realized; position of a universal pipe can be adjusted according to needs, and liquid with pressure flows out from the nozzle to be mixed with dust timely, so that air pollution of a working site is reduced; the liquid plays a role in cooling and lubricating, so that temperature of a drill bit is maintained normal, service life of the drill bit is prolonged, and faults caused by frequent replacement are avoided; normal working is guaranteed, environment of the working site is improved, physical health of operating personnel is benefited, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electromechanical products, and in particular relates to an impact drill with a liquid spraying device. Background technique [0002] There are many types and types of impact drills, which are widely used in mining, architectural decoration, municipal construction, electromechanical engineering, directional blasting and other engineering fields; but at present, a large amount of dust is generated when the impact drill is working; The temperature rises sharply, the temperature cannot be lowered, and there is no lubrication between the drill bit and the object to be drilled, resulting in the drill being hot, worn, and blunt; currently, the impact drill does not have a liquid spray device, which cannot solve the appeal problem and affects normal work. Contents of the invention [0003] The purpose of the invention is to overcome the problem that the existing percussion drill has no liquid injection device....
