Drill bit cooling dust-proof device

Abstract

A drill bit cooling dust-proof device comprises an outer cylinder body and an inner cylinder body both in a vertical arrangement, wherein the inner cylinder body is coaxially arranged inside the outercylinder body, an annular cavity is formed between the outer cylinder body and the inner cylinder body, and the upper ends of the inner cylinder body and the outer cylinder body are fixedly connectedthrough an upper annular plate; the lower end of the inner cylinder body is lower than the lower end of the outer cylinder body, and a conical barrel is fixedly connected to the lower end of the outer cylinder body; the structure of the conical barrel is thin in the upper and thick in the lower, the lower end of the conical barrel and the lower end of the inner cylinder body are fixedly connectedthrough a lower annular plate, and a pipe joint is arranged on the upper part of the outer cylinder body; a plurality of nozzles are evenly arranged on the lower annular plate in the circumferentialdirection, and an upper bearing assembly and a lower bearing assembly are arranged on the upper and lower parts of the inner wall of the inner cylinder body correspondingly. According to the device, the spread of dust during the construction of the drill bit is effectively prevented, and an auxiliary effect of cooling the working drill bit is achieved, so that the physical health of constructors is greatly guaranteed, and at the same time, the service life of the drill bit is prolonged, and the construction level is improved.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a temperature-cooling and dust-proof device for drill bits. Background technique [0002] Drill bits are an essential tool for mining engineering and are also widely used in various engineering fields. During the use of the drill bit, it is often accompanied by bursts of dust, which poses a threat to the health of the staff. Once the dust particles are inhaled by the human body, the viruses and bacteria carried in them are likely to cause respiratory tract infection. After long-term accumulation, it may even lead to pneumoconiosis, which seriously affects the respiratory function of the lungs. At present, there are no effective dust suppression measures during the drilling operation. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a drill bit cooling and dust-proof device with simple s...
