The connection between the pressure ring 28 and the protrusion 29 is a smooth transition to ensure that the pressing wheel 11 can roll smoothly from the pressure ring 28 and the protrusion 29.

[0034] When in use, the soil is loosened by the rotating rotary tiller 3 on the body 1. During this process, the cleaning rod 13 drives the multiple cleaning hooks 30 to rotate, so that when the rotary tiller 3 rotates to the cleaning hook 30, the rotating cleaning hook 30 can pull the grass wrapped on the rotary tiller 3 to remove the grass wrapped from the rotary tiller 3, so that the rotary tiller 3 can work normally. At the same time, the cleaning rod 13 will also drive the pressing wheel 11 to roll on the pressing ring 28 when driving the cleaning hook 30 to rotate. When the pressing wheel 11 rolls to the protrusion 29, it will drive the wheel seat 9 to move downward, so as to drive the pressing frame 12 to move and push the guide sleeve 25, so that the guide sleeve 25 can slide on the guide frame 24, and then drive the push plate 32 on the supporting frame 20. The cleaning hook 30 is moved to push the grass wrapped on the cleaning hook 30 toward the end of the cleaning hook 30. During this process, the blade 33 on the push plate 32 will cut the grass wrapped to cut off and remove it, so that a large amount of grass wrapped will not be attached to the cleaning hook 30 to affect the pulling effect of the cleaning hook 30. If the blade 33 is not sharp enough after long-term use, the locking column 15 can be directly pulled to allow the locking column 15 pushed out by the fixing spring 16 to be disengaged from the fixing socket 18 and the insert tooth 19, and then the carrier 20 is pulled outward to extract the insert tooth 19 from the fixing socket 18, so that the carrier 20 is disassembled, and then the blade 33 on the carrier 20 is polished or replaced to ensure the sharpness of the blade 33.
