A cooling and dust-proof device for a drill bit, comprising an outer cylinder and an inner cylinder both arranged vertically, the coaxial line of the inner cylinder is arranged inside the outer cylinder, an annular cavity is formed between the outer cylinder and the inner cylinder, and the inner cylinder The upper end of the outer cylinder is fixedly connected with the upper annular plate, the lower end of the inner cylinder is lower than the lower end of the outer cylinder, and the lower end of the outer cylinder is fixedly connected with a tapered cylinder. The tapered cylinder has a thin upper and thicker structure. The lower end of the cylinder and the lower end of the inner cylinder are fixedly connected by the lower annular plate, the upper part of the outer cylinder is provided with a pipe joint, and several nozzles are evenly arranged on the lower annular plate along the circumferential direction, and the upper and lower parts of the inner wall of the inner cylinder An upper bearing assembly and a lower bearing assembly are respectively provided. The invention can effectively prevent the dust from spreading during the drill bit construction process, and can also play an auxiliary role in cooling the working drill bit, which greatly protects the health of construction workers, and is also beneficial to prolong the service life of the drill bit and improve the construction level.
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...
