At this time, the rotating plate 5 is rotated to fix the fixed column 4 and the outside of the protective plate 3, thereby fixing the protective plate 3 to the top of the tiller casing 1, thereby realizing protection of the motor 2 and facilitating the disassembly of the protective plate 3 for maintenance and recycling, thereby saving production costs.

[0028] Reference Figure 1 and Figure 5 A retaining ring 12 is fixedly connected to the rear side of the tiller casing 1, and a nut 15 is threadedly connected to the front end of the threaded column 13. At this time, the nut 15 is rotated, and the retaining ring 12 expands outward under the rotation of the nut 15. The middle right side of the retaining ring 12 is threadedly connected to the threaded column 13, and the external thread of the threaded column 13 is connected to the elastic plate 14. At this time, the distance between the elastic plate 14 and the threaded column 13 is increased, and the threaded column 13 has room for movement. Then, the nut 15 is rotated, and the gap between the threaded column 13 and the elastic plate 14 is reduced. The middle part of the retaining ring 12 is slidably connected to the retaining column 19, and then the height of the retaining column 19 is adjusted according to the depth to be leveled, and the retaining column 19 is pulled according to demand.

[0029] An adjustment mechanism is provided on the right side of the tiller housing 1, and the adjustment mechanism includes a cavity 16, a second spring 17 and a card ball 18.

[0031] Working principle: first place the tiller casing 1 to a suitable position, then place the protective plate 3 to the top of the tiller casing 1, and then move the fixed column 4 downward. When the fixed column 4 enters the interior of the card slot 11, press the rotating plates 8 on both sides at the same time. At this time, the rotating plate 8 drives the moving column 7 to rotate. As the rotating plate 8 fits the limit groove, the moving column 7 will move downward. At this time, the top column 9 will move downward along the inner wall of the sliding groove 6. At the same time, the spring 10 is compressed. When the rotating plate 8 slides over the card slot 11, the rotating plate 8 is no longer subjected to force and expands outward under the reaction force of the spring 10. At this time, the top of the rotating plate 8 is engaged with the inner wall of the card slot 11. At this time, rotate the rotating plate 5 to fix the fixed column 4 and the outside of the protective plate 3, thereby fixing the protective plate 3 to the top of the tiller casing 1, and then adjust the height of the card column 19 according to the depth to be leveled. At this time The nut 15 is turned, and the retaining ring 12 is expanded outward under the rotation of the nut 15. At this time, the distance between the elastic plate 14 and the threaded column 13 increases, and the threaded column 13 has space to move. At this time, the retaining column 19 is pulled according to demand. During the pulling process, the second retaining groove 20 will squeeze the retaining ball 18. At this time, the retaining ball 18 moves toward the inside of the cavity 16 and squeezes the second spring 17. At this time, the second spring 17 is compressed. When the retaining ball 18 is engaged with another second retaining groove 20, the second spring 17 generates a reaction force on the retaining ball 18, so that the retaining ball 18 is fixed to the second retaining groove 20. Then, the nut 15 is turned, and the gap between the threaded column 13 and the elastic plate 14 is reduced, thereby locking the retaining column 19 through the retaining ring 12. Then, the motor 2 is started by the controller. Under the drive of the motor 2, the tiller head breaks and levels the soil, and then the push plate 21 levels the broken soil.
