[0018] Reference Figure 1-3This utility model provides an embodiment of an adaptive tillage depth adjustment garden management machine, comprising a body 1, with rollers 2 rotatably connected to both sides of the lower part of the body 1 for easy movement. A mounting base 3 is fixedly connected to the front end of the body 1, providing support. Limiting grooves 4 are formed on both sides of the bottom of the mounting base 3, serving a limiting function. Adjusting seats 5, T-shaped and corresponding to the limiting grooves 4, are slidably connected within each limiting groove 4. A mounting plate 6 is fixedly connected to the bottom of the adjusting seat 5, providing fixed support. Two limiting holes 7 are formed on the outer side of the adjusting seat 5, cooperating with limiting pins 9 for limiting. Evenly distributed through holes 8 are formed on both sides of the mounting base 3. A bidirectional threaded rod 10 passes through and rotatably connects to the two mounting plates 6. Moving blocks 12 are threadedly connected to both sides of the outer ring of the bidirectional threaded rod 10, enabling the two moving blocks 12 to move relative to or away from each other via the bidirectional threaded rod 10. Each of the two movable blocks 12 is rotatably connected to a support frame 15 on one side, which provides support. A lifting seat 13 is located below the bidirectional threaded rod 10, and grooves are provided on both sides of the lifting seat 13. Fixed plates 17 are fixedly connected to both sides of the bottom of the lifting seat 13, providing support. A rotating shaft 18 passes through and rotatably connects the two fixed plates 17. Evenly distributed loosening blades 19 are fixedly connected to the outside of the rotating shaft 18, allowing the loosening blades 19 to rotate via the rotating shaft 18.

[0019] Two through holes 8 are fitted with limit pins 9, the ends of which are located within limit holes 7 and threadedly connected to them. The limit pins 9, screwed into the limit holes 7, serve a limiting function. A first motor 11 is fixedly connected to the outer side of the left mounting plate 6, and its output is fixedly connected to a bidirectional threaded rod 10, allowing the motor 11 to rotate. A connecting seat 14 is fixedly connected to the top of the lifting seat 13, rotatably connected to the end of the support frame 15, serving a connecting function. Guide posts 16 are fixedly connected to the inner sides of both mounting plates 6, with limit blocks (not shown in the figure) at their bottom. The lifting seat 13 moves up and down along the guide posts 16 via grooves on both sides, improving stability. A second motor 20 is fixedly connected to the outer side of the left fixed plate 17, and its output is fixedly connected to a rotating shaft 18, allowing the second motor 20 to rotate.

The push handle 22, together with the roller 2, facilitates the movement of the body 1.

[0020] Working principle: When fine-tuning the front and rear positions of the loosening blade 19 is required, the two adjusting seats 5 slide within the limiting grooves 4 of the mounting base 3. The limiting pins 9 are inserted into the corresponding through holes 8 and screwed into the limiting holes 7 to fix the position of the adjusting seats 5, thus achieving fine-tuning of the front and rear positions of the loosening blade 19. When adjusting the loosening depth, the first motor 11 drives the bidirectional threaded rod 10 to rotate, causing the two moving blocks 12 to move towards or away from each other. The moving blocks 12, through the support frame 15, push the connecting seat 14 and the lifting seat 13 to slide up and down along the guide column 16, achieving precise adjustment of the vertical height of the loosening blade 19. The guide column 16 ensures the smooth movement of the lifting seat 13, preventing wobbling. The second motor 20 drives the rotating shaft 18 to rotate, causing the loosening blade 19 to rotate at high speed, achieving soil tillage.
