[0036] Embodiment 2

[0037] Please refer to Figure 1 And Figure 4As shown in the figure, an agricultural weeding and garden maintenance device is provided. Inside the inner wall of the protective shell 1 of the weeding device, a motor box 19 is welded. Inside the motor box 19, a mowing motor 22 is fixedly connected. On one side of the mowing motor 22, a motor rotating shaft 20 is integrally arranged. At one end of the motor rotating shaft 20, a mowing blade 21 is snap-connected. On the other side of the mowing motor 22, an electrical connection pipe 23 is electrically connected. At one end of the electrical connection pipe 23, a storage battery 24 is electrically connected. And on the top of the storage battery 24, a control element 25 is electrically connected. On the other side of the protective shell 1 of the weeding device, a medicine cylinder clamping block 27 is snap-connected. At the bottom of the medicine cylinder clamping block 27, a clamping block spring 30 is closely attached. On one side of the medicine cylinder clamping block 27, a medicine placement cylinder 28 is integrally arranged. And on one side of the medicine placement cylinder 28, a jitter pedal 29 is welded. Inside the protective shell 1 of the weeding device, a pressing wheel rotating shaft 31 is rotatably connected. And on the outer wall of the pressing wheel rotating shaft 31, a land leveling pressing wheel 32 is welded.

[0038] The mowing blade 21 is rotatably connected to the mowing motor 22 through the motor rotating shaft 20, and the outer diameter of the mowing blade 21 is smaller than the inner diameter of the protective shell 1 of the weeding device. Then, when the power is turned on, after the control element 25 receives the instruction, the storage battery 24 provides power to the mowing motor 22. The mowing motor 22 drives the motor rotating shaft 20 and the mowing blade 21. After the mowing blade 21 cuts the weeds, the grass clippings fall inside the protective shell 1 of the weeding device and the front baffle 3.

[0039] The land leveling pressing wheel 32 is rotatably connected to the protective shell 1 of the weeding device through the pressing wheel rotating shaft 31, and the protective shell 1 of the weeding device and the medicine cylinder clamping block 27 form an elastic structure through the clamping block spring 30. When the land leveling pressing wheel 32 is placed down, while the weeding device is moving forward, the road surface can be flattened by the rotation of the land leveling pressing wheel 32, which also facilitates other subsequent operations. If there are small weeds that are difficult to cut, or if drugs need to be spread, an appropriate amount of agricultural drugs or drugs to be spread can be introduced into the medicine placement cylinder 28. When it is necessary to sprinkle, step on the jitter pedal 29. The jitter pedal 29 drives the medicine cylinder clamping block 27 downward. The medicine cylinder clamping block 27 presses the clamping block spring 30 downward. When the jitter pedal 29 is released, the clamping block spring 30 rebounds upward. When moving up and down, the mesh-like setting at the bottom of the medicine placement cylinder 28 will sprinkle the powdery or other drugs inside, for secondary treatment of the ground.

[0040] Working principle:

[0041] First, push the weeding device onto the grass that needs to be weeded and check if the large adjusting roller 18 is damaged. If it is damaged, the roller can be removed and replaced by turning the fixing screw 17 of the rotating shaft. When pushing the weeding device, the height of the tires can be adjusted according to different ground conditions. After lifting the front or rear wheel that needs to be adjusted, the large adjusting roller 18 drives the outer rotating shaft 16, the rotating shaft linkage rod 15, and the inner rotating shaft 14. After adjusting the inner rotating shaft 14 to the corresponding height slot of the roller moving slot 13, lower the large adjusting roller 18. The inner rotating shaft 14 will be stuck in the corresponding slot along the inclined slot. Then, turn on the power. After the control element 25 receives the instruction, the storage battery 24 supplies power to the mowing motor 22. The mowing motor 22 drives the motor rotating shaft 20 and the mowing blade 21. After the mowing blade 21 cuts the weeds, the grass clippings fall inside the weeding device protective shell 1 and the front stop 3. Then, the weed sorting plate 11 will sort and stack the cut weeds in the grassland. After accumulating a certain amount, pull the grass raking plate towing rod 7. The grass raking plate towing rod 7 drives the grass raking plate transmission block 8 to rotate, and drives the grass raking plate fixing plate 10 through the transmission block rotating shaft 9. After the grass raking plate fixing plate 10 rotates to a certain angle, it no longer blocks the weed sorting plate 11, and the weed sorting plate 11 rotates backward. The stacked cut grass will be diverted into two rows by the sub-groove pushing plate 26 and left on the grassland that has been passed. The piled-up weeds are convenient for subsequent cleaning and treatment. At the same time, when encountering plants that are not flexible enough to enter the front stop 3, the fixed towing rope 5 can be pulled. The fixed towing rope 5 drives the towing rope fixing ring 4, thereby driving the front stop 3. The front stop 3 rotates to fit the weeding device protective shell 1 through the hinge 2, and the mowing blade 21 is exposed, which can better cut plants with a certain hardness.

[0042] Next, when mowing the grass, if encountering uneven land or needing to flatten the land, the rear wheel can be adjusted and the land leveling roller 32 can be placed down. While the weeding device is moving forward, the road surface can be flattened by the rotation of the land leveling roller 32, which is also convenient for other subsequent operations. If there are small grasses that are difficult to cut or drugs that need to be sprinkled, an appropriate amount of agricultural drugs or drugs to be sprinkled can be introduced into the drug placement cylinder 28. When it is necessary to sprinkle, step on the jitter pedal 29. The jitter pedal 29 drives the drug cylinder locking block 27 downward. The drug cylinder locking block 27 presses the locking block spring 30 downward. When the jitter pedal 29 is released, the locking block spring 30 rebounds upward. During the up and down movement, the mesh-like setting at the bottom of the drug placement cylinder 28 will sprinkle the powder or other drugs inside, and perform secondary treatment on the ground.
