The drive gear 6 is meshed with a driven gear 7 on its outer wall. The mounting frame 2 has a "U" shaped cross section. The drive bevel gear 103 is meshed with a driven bevel gear 4 on its outer wall. A rotating block 5 is provided on the outer walls of the driven bevel gear 4, the drive gear 6, and the driven gear 7. The outer wall of the rotating block 5 is provided with a mounting groove 501. The cleaning roller 3 is symmetrically arranged on both sides of the blade 102. The outer wall of the cleaning roller 3 is in contact with the outer wall of the blade 102. The length of the cleaning roller 3 is greater than the diameter of the blade 102. The drive gear 6 and the driven gear 7 are correspondingly arranged.
[0026] When the main body 1 of the weeder is started, the output shaft 101 drives the blade 102 to rotate at high speed to perform weeding. At this time, the active bevel gear 103 fixed on the outer wall of the output shaft 101 rotates synchronously and drives the rotating block 5 to rotate through the meshing driven bevel gear 4. The mounting groove 501 on the outer wall of the rotating block 5 and the hexagonal cross section of the connecting shaft 301 form a transmission fit, so that the connecting shaft 301 drives the cleaning roller 3 to rotate synchronously. Since the cleaning roller 3 is symmetrically arranged on both sides of the blade 102 and its outer wall is in contact with the blade 102, it can physically scrape off the weed residue, juice and dirt attached to the surface of the blade 102 during its rotation. At the same time, the active gear 6 and the driven gear 7 inside the mounting frame 2 mesh to ensure that the rotation direction of the cleaning roller 3 on both sides is consistent and the speed is synchronized, avoiding the blade 102 from being deflected due to uneven cleaning force on one side, thereby achieving efficient and uniform cleaning of the blade 102, preventing weed juice from corroding the blade 102 in real time, and improving the durability of the equipment.
