When the rotating motor moves downward, it will drive the cleaning brush disc to move downward, and then the rotating motor rotates to drive the cleaning brush disc to rotate and cooperate with the spraying device to clean the metal grinding disc.

[0007] According to the above technical solution, a first spring is sleeved on the surface of the fixing rod, and the baffle contacts the surface of the partition. When the hand releases the arc-shaped sliding plate, the elastic force of the first spring itself will drive the arc-shaped sliding plate to reset.

[0008] According to the above technical solution, a limiting device for preventing the metal grinding disc from moving and a supporting device for supporting the equipment are arranged on the chassis. The limiting device includes a connecting plate, a pulley frame, a fixing plate and a trapezoidal slider. The electric telescopic rod moves downward to drive the connecting plate to move downward. The downward movement of the connecting plate will drive the pulley frame to move downward. The downward movement of the pulley frame will contact the trapezoidal slider. The connecting plate is fixedly installed at the output end of the electric telescopic rod. The pulley frame is fixedly installed at the bottom of the connecting plate. The fixing plate is fixedly installed on the inner wall of the chassis. The trapezoidal slider is slidably installed on the top of the fixing plate.

[0009] According to the above technical solution, a sliding rod is slidably installed on the inner wall of the chassis. A rotating plate is rotatably installed on the surface of the sliding rod. A sealing ring is arranged inside the spraying device. A hollow sliding rod is slidably installed on the inner wall of the sealing ring. A triangular block is fixedly installed on the surface of the hollow sliding rod. A short rod is arranged on the surface of the sliding rod. The movement of the short rod towards the spraying device will push the triangular block towards the sealing ring. The movement of the triangular block towards the sealing ring will drive the hollow sliding rod towards the sealing ring.

[0010] According to the above technical solution, a second spring is arranged between the trapezoidal slider and the fixed plate. When the pulley frame is separated from the trapezoidal slider, the self-elastic force of the second spring will drive the trapezoidal slider to reset. The short rod is in contact with the surface of the triangular block. A third spring is arranged between the chassis and the sliding rod. When the pulley frame is reset, the third spring that loses the extrusion of the pulley frame will drive the sliding rod to reset.

[0011] According to the above technical solution, the support device includes a connecting rod, a square plate, a support block and a trapezoidal plate. By moving the sliding rod in the direction close to the spraying device, the connecting rod is driven to move in the direction close to the spraying device. When the connecting rod moves in the direction close to the spraying device, the square plate will be driven to move in the direction close to the spraying device. The connecting rod is fixedly installed at the bottom of the sliding rod, the square plate is fixedly installed at the bottom of the connecting rod, the support block is slidably installed on the inner wall of the chassis, and the trapezoidal plate is fixedly installed on the surface of the support block.

[0012] According to the above technical solution, a long rod is fixedly installed at the bottom of the square plate. A drain groove is formed inside the chassis.

When the long rod moves in the direction close to the spraying device, it will push the trapezoidal block to move away from the drain groove. When the trapezoidal block moves away from the drain groove, it will drive the sealing baffle to move away from the drain groove.

[0013] According to the above technical solution, a fifth spring is arranged between the support block and the chassis. When the square plate is separated from the trapezoidal plate, the self-elastic force of the fifth spring will drive the support block to reset. A sixth spring is arranged between the drain groove and the sealing baffle. When the long rod is separated from the trapezoidal block, the self-elastic force of the sixth spring will drive the sealing baffle to reset.

[0014] The present invention provides a surfacing equipment for the metal grinding disc of a ball mill. It has the following beneficial effects: (1) In this invention, first, the driving device drives the placing disc to move to the outside of the chassis. Then, by pulling the arc-shaped slide plate to move away from the middle of the placing disc, and then placing the metal grinding disc of the ball mill on the placing disc. When the arc-shaped slide plate is released, the self-elastic force of the first spring will drive the arc-shaped slide plate to reset and clamp the metal grinding disc. The cooperation of the baffle and the partition plate prevents water from flowing into the driving device during spraying, resulting in equipment damage and affecting subsequent surfacing. When the cleaning is completed, the driving device drives the metal grinding disc into the surfacing box, and the surfacing device inside the surfacing box repairs the worn or damaged metal grinding disc to extend its service life and improve the efficiency of the ball mill.

[0015] (2) In this invention, the arc-shaped slide plate is pressed against by the trapezoidal slider to prevent the metal grinding disc from rotating along with the cleaning brush disc during the cleaning rotation, which affects the cleaning effect. At the same time, when the triangular block moves towards the sealing ring, it will drive the hollow slide rod to move towards the sealing ring. When the hollow slide rod moves towards the sealing ring, the spraying device will spray, eliminating the need for manual operation and improving work efficiency.

[0016] (3) In this invention, the support block moves upward to support the bottom of the placement tray, preventing instability during cleaning that may cause the placement tray to shake and affect the normal use of the device. At the same time, when the trapezoidal block moves away from the drainage groove, it will drive the sealing baffle to move away from the drainage groove. By moving the sealing baffle away from the drainage groove, the drainage groove is opened, allowing the water generated during the spraying of the spraying device to drain away, preventing excessive water accumulation that may affect the normal use of the device.
