[0032] As a technical optimization solution of the present utility model, by providing the reinforcing blocks 11, the structural strength of the moving frame 6 can be enhanced, preventing the moving frame 6 from deforming during long-term use, resulting in the inability to use the moving frame 6 normally, and improving the usage stability of the moving frame 6.

[0033] Reference Figure 1 , a protective shell 12 is provided outside the motor 74, and the surface of the protective shell 12 is fixedly connected to the surface of the rotary tillage seat 2.

[0034] As a technical optimization solution of the present utility model, by providing the protective shell 12, the first helical gear 72 and the second helical gear 73 can be shielded and protected, preventing foreign objects from the outside from contacting the first helical gear 72 and the second helical gear 73, resulting in jamming at the meshing part of the first helical gear 72 and the second helical gear 73, and improving the cooperation safety of the first helical gear 72 and the second helical gear 73.

[0035] Working principle and usage process of the present utility model: When in use, when it is necessary to clean the inner wall of the protective cover 1, start the motor 74. The motor 74 drives the second helical gear 73 to rotate. The second helical gear 73 drives the first helical gear 72 to rotate. The first helical gear 72 drives the screw rod 71 to rotate. The screw rod 71 drives the moving frame 6 to move. The moving frame 6 drives the transmission block 5 to move. The transmission block 5 drives the scraper 4 to move. During the movement of the scraper 4, the adhered rotary tillage materials on the inner wall of the protective cover 1 are scraped off. There is no wear of the rotary tillage materials on the rotary tillage tool holder 3, and the rotary tillage tool holder 3 can be used for a longer time.

[0036] In summary, for the rotary tillage tool for agricultural use with a protection function, through the combined use of the protective cover 1, the rotary tillage seat 2, the rotary tillage tool holder 3, the scraper 4, the transmission block 5, the moving frame 6 and the control mechanism 7, it solves the problem that the protective plate is used to block the rotary tillage materials to prevent the rotary tillage materials from splashing everywhere to protect the user. However, the rotary tillage materials will adhere to the inner wall of the protective plate. When the rotary tillage materials accumulate to a certain thickness, the rotary tillage materials will impact the rotary tillage blades, and this behavior will accelerate the wear of the rotary tillage blades, resulting in a significant reduction in the service life of the rotary tillage blades.
