When the cylinder 4 is in a retracted position, the top wall of the rotating rod 12 contacts the inner ring end wall of the support sleeve 6, so that the two symmetrically installed scrapers 13 tilt downward, and the tilt angle is centered on the axis of the shell. When the cylinder 4 pushes the motor 5 to move downward, the top wall of the rotating rod 12 is separated from the limit fixation of the support sleeve 6, and the bottom end of the scraper 13 contacts the bottom wall of the shell. As the motor 5 continues to drive the stirring The rod 10 moves downward, and the scraper 13 reacts with the bottom wall of the shell and opens toward the side wall of the shell until the bottom wall of the scraper 13 completely contacts the bottom wall of the shell. The length of the two symmetrically rotatably mounted scrapers 13 is equal to the inner diameter of the shell. The cylinder 4 is powered off, and the motor 5 stops moving downward. The output end of the motor 5 rotates slowly, driving the scraper 13 to rotate slowly. The rotating rod 12 and the scraper 13 are rotatably mounted on the stirring rod 10, thereby increasing the cleaning area of ​​the cleaning device and enabling a more comprehensive cleaning of the bottom wall of the shell.

The distance between the side wall of the blocking block 9 and the axis of the shell is greater than the maximum distance between the drain hole 17 and the axis of the shell, but less than the distance between the axis of the waste hole 27 and the axis of the shell. When cleaning impurities, the sliding impurities slide along the side wall of the scraper 13 toward the axis of the shell and enter the waste hole 27. The bottom wall of the blocking block 9 contacts the bottom of the shell. At this time, the outer wall of the blocking block 9 is located above the waste hole 27, and the blocking block 9 blocks the impurities. Under the joint action of the blocking block 9 and the scraper 13, the impurities enter the waste hole 27 to prevent the impurities from entering the drain hole 17.

When the spring 21 is in an initial state, a part of the protrusion contacts the first electric block 22. When the motor 5 moves downward, the bottom wall of the sliding block 25 contacts the top wall of the protrusion and continues to push the second electric block 23 downward. The spring 21 is stretched, the first electric block 22 and the second electric block 23 are separated from each other, the power line of the cylinder 4 is disconnected, the output end of the cylinder 4 stops moving downward, and the motor 5 stops moving downward. At this time, the bottom end of the stirring just contacts the bottom wall of the shell, and the shaft of the motor 5 rotates slowly again, driving the stirring blade 11 and the scraper 13 to slowly clean the impurities on the bottom wall of the shell.
