[0033] Specifically, the connecting rod 501 and the two sets of gears 5 are driven to rotate by rotating the rocker 502. When the two sets of gears 5 rotate, the lifting tooth plate 4 is driven to lift and lower inside the adjusting plate 2. When the lifting tooth plate 4 is lifted and lowered, the limit plate 3 and the two sets of grooming rods 301 can be driven to lift and lower, so as to facilitate the adjustment of the height of the two sets of grooming rods 301, so that the two sets of grooming rods 301 can push away hard objects such as stones on the ground, and effectively protect the two sets of mowing blades 9. After the adjustment of the grooming rods 301 is completed, the lifting tooth plate 4 is fixed and limited by the fixing assembly, so as to improve the stability of the two sets of grooming rods 301, so as to facilitate the pushing away of hard objects such as stones.

[0034] Reference Figure 2-4 The fixed component includes a fixed tooth plate 6, which is slidably connected to one side of the adjusting plate 2, and the fixed tooth plate 6 is meshed with the lifting tooth plate 4. One end of the fixed tooth plate 6 is connected to a pull rod 603, and the other end of the pull rod 603 extends to the outside of the adjusting plate 2 and is connected to a pull ring 602. A spring 601 is installed on the surface of the pull rod 603 located inside the adjusting plate 2, and one end of the spring 601 is connected to the fixed tooth plate 6, and the other end of the spring 601 is connected to the inner wall of the adjusting plate 2.

[0035] Specifically, by pulling the pull ring 602, the fixed tooth plate 6 and the pull rod 603 are moved, so that the fixed tooth plate 6 is meshed with the lifting tooth plate 4, the lifting tooth plate 4 can be limited and fixed, and the elastic action of the spring 601 can make the fixed tooth plate 6 always fit with the lifting tooth plate 4, thereby improving the stability of the fixed tooth plate 6.

[0036] Reference Figure 1-3 Two sets of transmission shafts 901 are connected to one side of the cart 1, and the bottoms of the two sets of transmission shafts 901 are connected to the two sets of mowing blades 9. The tops of the two sets of transmission shafts 901 are located on the surface of the cart 1 and a driving assembly is arranged.

Transmission belts 903 are installed inside the two sets of connecting shafts 902, and a driving motor 904 is connected to the top of one set of connecting shafts 902.

[0037] Specifically, a driving motor 904 drives a group of connecting shafts 902 to rotate. After one group of connecting shafts 902 rotates, the other group of connecting shafts 902 rotate synchronously under the action of the transmission belt 903. After the two groups of connecting shafts 902 rotate, they can drive the lawn mower 9 and the transmission shaft 901 to rotate, and the lawn mower 9 can remove the weeds.

[0038] Reference Figure 2-4 Two sets of mounting frames 801 are installed on one side of the two sets of mowing blades 9, and the two sets of mounting frames 801 are rotatably connected to the soil-turning roller 8 inside. Multiple sets of soil-turning blades 802 are installed on the surface of the soil-turning roller 8. A spray box 7 is installed on one side of the two sets of mounting frames 801, and a medicine adding port 701 is connected to the top of the spray box 7, and multiple sets of spray heads 702 are connected to the bottom of the spray box 7.

[0039] Specifically, through the functions of two sets of mounting frames 801, tilling blades 802 and tilling rollers 8, the soil can be loosened after the mowing blades 9 have finished weeding, which is convenient for the subsequent planting of fruit trees. At the same time, the grass roots can be completely removed to improve the weeding effect. After the loosening of the soil is completed, the spray box 7, the medicine adding port 701 and the spray head 702 can cooperate to spray the soil with medicine, which is convenient for the planting of fruit trees.

[0040] Reference Figure 1-3 A push rod 101 is connected to the side of the cart 1 away from the adjustment plate 2, and four sets of moving wheels 102 are installed at the bottom of the cart 1.

[0041] Specifically, the push rod 101 facilitates the staff to push the cart 1 to move, and the four sets of moving wheels 102 at the bottom facilitate the movement of the cart 1.

[0042] Working principle: When in use, connect the mobile power supply and the controller to the device, add the corresponding medicine into the spray box 7 through the medicine adding port 701, pull the pull ring 602 to drive the fixed tooth plate 6 and the pull rod 603 to move, so that the fixed tooth plate 6 is separated from the lifting tooth plate 4, and the fixing effect of the lifting tooth plate 4 is released, and the two sets of rocking wheels 502 are rotated to drive the gear 5 to rotate, and when the gear 5 rotates, it drives the lifting tooth plate 4 to rise and fall inside the adjustment plate 2, and when the lifting tooth plate 4 rises and falls, it drives the limit plate 3 and the two sets of sorting rods 30 1 is lifted and lowered so that the two groups of grooming rods 301 are inserted into the soil, and the driving motor 904 is started to drive the two groups of mowing blades 9 to rotate, and the cart 1 is pushed to move. When the cart 1 moves, the two groups of grooming rods 301 can push away hard objects such as stones on the ground to prevent the mowing blades 9 from being damaged. After the mowing blades 9 have finished weeding, the soil-turning roller 8 and the soil-turning blade 802 loosen the soil to facilitate the planting of fruit trees. After the soil loosening is completed, the spray head 702 sprays the medicine inside the spray box 7 to completely remove the weeds.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
