A connecting rod 2 is arranged on the stirring shaft 1, the connecting rod 2 is installed on the stirring shaft 1, and a scraper 3 is arranged on one side of the connecting rod 2. An adjusting assembly 4 is arranged on the connecting rod 2, the adjusting assembly 4 adjusts the scraper 3 to tightly press against the inner wall of the tank body, and the scraper 3 on the connecting rod 2 scrapes the material on the inner wall of the tank body with the rotating shaft 31.

[0027] The connecting rod 2 is in the shape of a frame, and the frame-shaped cross section of the connecting rod 2 is rectangular, and the length direction of the cross section of the connecting rod 2 is parallel to the axis direction of the connecting rod 2, and one side of the length direction of the connecting rod 2 is provided with a connecting disc 21, and the connecting rod 2 is welded on the connecting disc 21. In addition, the stirring shaft 1 is provided with a rotating disc 12, the rotating disc 12 is coaxial with the stirring shaft 1, the connecting disc 21 is provided with a connecting bolt 22, one end of the connecting bolt 22 penetrates through the connecting disc 21 and is connected with the rotating disc 12. In use, the connecting rod 2 drives the connecting disc 21 to rotate through the rotating disc 12, and with the rotation of the connecting disc 21, the connecting rod 2 rotates in the tank.

[0028] In order to scrape the material in the tank, a group of scrapers 3 is installed on each side in the width direction and one side in the length direction of the connecting rod 2. In use, the scrapers 3 on both sides in the width direction of the connecting rod 2 process the inner wall of the tank, and the scraper 3 on one side in the length direction of the connecting rod 2 processes the bottom of the tank. The structures and functions of the three groups of scrapers 3 are the same, only the positions on the connecting rod 2 are different, so only the scraper 3 on one side in the width direction of the connecting rod 2 is described.

[0029] Referring to Figures 2-3 , the adjusting assembly 4 comprises an adjusting plate 41, the adjusting plate 41 is in the shape of a rectangular plate, the connecting rod 2 is provided with a guide groove 23, the adjusting plate 41 is provided with an adjusting block 42, two adjusting blocks 42 are arranged along the length direction of the adjusting plate 41, one end of the two adjusting blocks 42 is connected with the adjusting plate 41, and the other end penetrates through the guide groove 23.
