The auxiliary plowshare comprises a plowshare main plate and a plowshare welded to the front of the plowshare main plate. The plowshare main plate is parallel to the side plates, the plowshare is perpendicular to the plowshare main plate, and the bottom end of the plowshare has a pointed bottom. This method provides a simple and reasonable structure. During tillage, the auxiliary plowshare helps the rotary tiller penetrate deeper into the soil, achieving a good deep tillage effect without leaving the soil uncultivated.

[0028] Specifically, a first push block 5 is connected to the inner wall of the first cavity 3. This first push block 5 is connected to a first push rod 6 at the center of its bottom end. This first push rod 6 acts like a bridge, transmitting force to the movable rod 7 below, thereby driving the movable rod 7 to slide within the second cavity 4. The movable rod 7 acts as an intermediary, its end tightly integrated with the connecting plate 8. Finally, the left edge of the connecting plate 8 seamlessly connects to the plowshare 10. The entire structure is designed to ensure that when the plowshare 10 needs to adjust the tillage depth, the linkage between the first push block 5, the first push rod 6, and the movable rod 7 allows for precise and powerful movement to meet various complex tillage needs.

[0029] Reference Figure 1 、 Figure 3 and Figure 4The adjusting mechanism 9 includes a first mounting groove 901, which is opened at the inner left end of the connecting plate 8. The inner side wall of the first mounting groove 901 is fixedly connected to a second push block 902. The middle part of the right end of the second push block 902 is fixedly connected to a second push rod 903. Two first assembly holes 904 are opened on the right side of the top of the second push rod 903. The right end of the plowshare 10 is hinged with two plow wings 905. The adjacent sides of the two plow wings 905 are each provided with a second mounting groove 906. The two second mounting holes 906 are fixedly connected to the inner side wall of the first mounting groove 901. The inner side walls of the groove 906 are fixedly connected to the steering blocks 907, and the adjacent sides of the two steering blocks 907 are rotatably connected to the support rods 908. The adjacent ends of the two support rods 908 are each provided with a second assembly hole 909.
