[0023] A hidden groove is provided on the upper end surface of the vertical plate 1, and a rotating motor is provided at the bottom of the hidden groove. A turntable 10 is provided above the vertical plate 1, and the turntable 10 is connected to the rotating motor through a lower lifting mechanism. A wiping assembly 11 is installed on the bottom wall of the turntable 10, and a water pump 12 and a pump liquid box 13 are installed on the upper end surface of the turntable 10. A water spray pipe connected to the water pump 12 is installed on the bottom wall of the turntable 10, and a piston plate 18 is sealed and slidably provided in the pump liquid box 13. A support frame 14 is provided on the upper end surface of the pump liquid box 13, and the piston plate 18 is connected to the support frame 14 through an upper lifting mechanism.

[0024] A liquid outlet pipe connected to the pump liquid box 13 is installed on the bottom wall of the turntable 10, and a liquid inlet pipe is installed on the outer wall of the pump liquid box 13. A first one-way valve is provided in the liquid inlet pipe, and a second one-way valve is provided in the liquid outlet pipe. The longer end of the liquid inlet pipe is in the cleaning liquid storage tank, and the one-way flow of the cleaning liquid is achieved by means of the first one-way valve and the second one-way valve.

[0025] A collecting trough 8 is provided below the vertical plate 1, and a support leg is installed on the bottom wall of the vertical plate 1, and the support leg is tilted. The inner bottom wall of the collecting trough 8 is convex, and a drain pipe is provided on the side wall of the collecting trough 8, and an electric valve is provided in the drain pipe. The support leg is tilted to ensure the stability of the vertical plate 1 and other components. The inner bottom wall of the collecting trough 8 is convex, which facilitates the liquid to enter the two ends of the collecting trough 8, and then the electric valve is opened to discharge through the drain pipe.

[0026] The limiting mechanism includes a limiting rod 5 arranged in the rotating groove 2, and the limiting rod 5 slides through the moving block 4. The limiting rod 5 is arranged parallel to the double-headed screw 3, which realizes the limiting operation of the moving block 4 to prevent it from rotating with the double-headed screw 3, and an adjusting motor 6 connected to the double-headed screw 3 is installed on the outer wall of one side of the vertical plate 1.

After the chain on the bucket elevator is installed, the adjusting motor 6 is started to drive the double-headed screw 3 to rotate. When the double-headed screw 3 rotates, the moving block 4 on its outer wall drives the two sprocket wheels 7 to move away, so that the chain is gradually tightened.

[0030] Subsequently, the wiping assembly 11, water pump 12 and pump liquid box 13 are lifted, rotated and adjusted with the help of the rotating motor and the lower cylinder 9, and the liquid outlet pipe, the wiping assembly 11 and the water spray pipe are adjusted in turn to correspond to the chain; at the same time, the rotating motor 17 is started, which drives the chain to rotate with the help of the sprocket 7, so that the entire chain can be stained with cleaning liquid, the wiping assembly 11 can wipe the entire chain, and the water spray pipe can realize the flushing operation of the entire chain.

[0031] Finally, the rotating motor 17 cooperates with the sprocket 7 to drive the chain to rotate continuously, so that the liquid on the chain can be shaken off. Finally, the double-headed screw 3 is reversed to release the tension of the chain, and then the chain can be removed.
