Adjustable mining drill bit cleaning device

The invention discloses an adjustable mining drill bit cleaning device which comprises a shell. A pressure-bearing cover is fixed onto the shell; a servo motor is installed on the outer side of the pressure-bearing cover; a motor shaft bearing on the servo motor penetrates through the pressure-bearing cover; a rotor is in key connection with the outer side of a motor shaft in the pressure-bearing cover; and a water conveying hose is arranged between the rotor and the inner wall of the pressure-bearing cover. According to the adjustable milling drill bit cleaning device, cleaning can be conducted according to the ultrasonic cleaning principle; in the cleaning process, a drill bit rotates, and the water flow direction is opposite to the rotating direction of the drill bit, so that the cleaning effect and the cleaning efficiency can be improved; meanwhile, the inclination angle of inclined rotation of the drill bit can be changed according to the size of the drill bit, so that the cleaning effect and the cleanin
