The plow tooth rod 32 drives the upper support arm 31 to rotate with the third hinge shaft 33 as the axis. With the cooperation of the plow tooth rod 32 and the loosening disk 26, the large soil particles in the soil turned over by the positioning arm 7 are crushed again. Processing is used to facilitate subsequent greening maintenance. When the plow tooth rod 32 moves, when the plow tooth rod 32 is blocked by hard soil, the plow tooth rod 32 can rotate with the third hinge shaft 33 as the axis to elastically protect the plow tooth rod 32 to prevent the rigidity of the plow tooth rod 32 from breaking. The side cylinder 18 drives the linkage arm 19 to rotate through the second hinge shaft 25, and the linkage arm 19 drives the power shaft 20 to rotate. The power shaft 20 drives the rocker arm 22 to rotate, and the rocker arm 22 drives the hub shaft 30 and the walking wheel 23 to rotate. When the power shaft 20 rotates, the fixed sleeve 21 provides a movable The support is used to facilitate driving the four sets of walking wheels 23 to rotate, to facilitate lifting the front frame 5, the main frame 2, and the rear frame 4 to a higher place, to facilitate loosening operations at different depths. The middle cylinder 13 drives the lower swing arm 14 to move through the upper clamping shaft 15, and the lower swing arm 14 drives the side frame 3 to rotate with the first hinge shaft 16 as the axis. The main frame 2 supports the upper clamping shaft 15 through the limiting arm 17 to facilitate the expansion of the two sets of side frames 3, to facilitate the adjustment of the loosening area.
