By setting the angle adjustment groove 4 on the main shaft 3 and matching the positioning connection block 5 that can adjust the angle of the scraper 8, after the scraper 8 is worn, the angle of the scraper 8 can be adjusted so that the scraper 8 has an angular position in contact with the wall surface for shoveling operation, thereby quickly improving the shoveling efficiency without manual grinding or replacement of the tool, which is beneficial to improving work efficiency and reducing use costs.

[0026] In actual use, Figure 4 As shown, in the initial state, the scraper 8 is arranged along the radial direction of the main shaft 3, and the working end of the scraper 8 has an original blade. As the main shaft 3 rotates, the blade of the scraper 8 contacts and wears the wall surface. The wear area 28 of the scraper 8 at the initial angle is as shown in FIG. Figure 4 As shown, after wear, the contact area between the scraper 8 and the wall surface becomes larger, and the scraping efficiency decreases; Figure 5 As shown, the positioning connection block 5 is removed from the angle adjustment slot 4, and the angle is adjusted to the left and then reinstalled into the angle adjustment slot 4. At this time, the scraper 8 contacts the wall surface again at the side edges and corners after being worn at the initial angle, and the surface contact is changed to line contact, thereby improving the working efficiency. At this angle, the scraper 8 wear area 28 is as shown in FIG. Figure 5 As shown, after the scraper 8 is worn again, the edges and corners are generated again; Figure 6 As shown, after the scraper 8 is adjusted again, the worn edges generated at the previous working angle are brought into contact with the wall surface, and the worn area 28 at the second angle is as shown in FIG.
