The drive motor drives the first drive wheel to rotate, and after being driven by the transmission belt, the open ring body rotates around the trunk. At the same time, the second drive wheel rotates around the trunk, and the second drive wheel drives the hollow vertical roller to rotate. The whitewashing agent in the material cylinder enters the hollow vertical roller through the connecting pipe. Under the action of centrifugal force, the whitewashing agent is thrown out from each discharge hole, and the brush on the hollow vertical roller applies the whitewashing agent to the trunk. Because the hollow vertical roller is in a rotating state, the residual amount of whitewashing agent on the brush can be effectively reduced under the action of centrifugal force, which is conducive to the brush applying the whitewashing agent to the outer wall of the trunk. The structure is more scientific and reasonable, which facilitates the connection between the whitewashing mechanism and the tree. The whitewashing agent is supplied through a closed pipeline, which effectively reduces the risk of leakage, further increases the coating area, and improves the whitewashing efficiency of the trees.

A drive assembly for driving the open ring body 3 to rotate is mounted on the open ring frame 1. The drive assembly includes two first drive wheels 4, a transmission belt 5 sleeved on the two first drive wheels 4, and a drive motor 6 that provides power for the rotation of the first drive wheels 4. The transmission belt 5 is tightly... The whitening mechanism includes a frame 7 fixedly connected to the open ring 3, a U-shaped frame 8 installed on the frame 7, a hollow vertical roller 9 rotatably installed on the U-shaped frame 8, a second drive wheel 10 fixedly installed on the hollow vertical roller 9, a material cylinder 11 and a connecting pipe 12 installed on the top of the frame 7. One end of the connecting pipe 12 extends into the bottom of the material cylinder 11, and the other end of the connecting pipe 12 is rotatably and sealingly connected to the top of the hollow vertical roller 9. The hollow vertical roller 9 is provided with multiple rows of brushes 24 and a discharge hole 13 communicating with the inside of the hollow vertical roller 9. Furthermore, the outer wall of the open ring 3 is in close contact with the outer diameter of the limiting wheel 2; the distance between the two first drive wheels 4 is greater than the size of the opening on the open ring 3; the connecting pipe 12 is connected to the interior of the hollow vertical roller 9, and the connecting pipe 12 is connected by a rotating seal such as a mechanical shaft seal; an electric control valve is installed on the connecting pipe 12, and in the non-use state, the connecting pipe 12 is blocked by the electric control valve to prevent the whitening agent in the barrel 11 from flowing out; the connecting pipe 12 is made of a plastic flexible hose.

[0030] For details, please refer to Figure 1 or Figure 3 A baffle 14 is fixedly installed on the U-shaped frame 8, and the baffle 14 covers the hollow vertical roller 9; furthermore, the baffle 14 is located on the side of the hollow vertical roller 9 away from the tree to be whitened; the brush 24 is in close contact with the inner wall of the baffle 14.

[0031] For details, please refer to Figure 3 A slide rod 15 is fixedly installed on the U-shaped frame 8. The slide rod 15 is slidably installed on the frame body 7. A spring 16 is sleeved on the slide rod 15. The U-shaped frame 8 is elastically connected to the frame body 7 through the spring 16. Furthermore, one end of the spring 16 abuts against the U-shaped frame 8, and the other end of the spring 16 abuts against the frame body 7. An anti-detachment cap is screwed onto the end of the slide rod 15.

[0032] For details, please refer to Figure 1 The single-row brushes 24 are arranged in a spiral curve around the outer wall of the hollow vertical roller 9.

[0035] The whitewashing device for garden tree maintenance provided in this embodiment can block the whitewash that is not thrown out on the side of the hollow vertical roller 9 that is not facing the tree. During the rotation of the brush 24, the whitewash on the inner wall of the baffle 14 is re-adhered to the brush 24. The whitewash is then applied to the trunk of the tree by the brush 24, which can improve the uniformity of the whitewash application and reduce the waste of whitewash.

[0036] Under the action of spring 16 and slide bar 15, the second drive wheel 10 and brush 24 can make elastic contact with the outer wall of the tree trunk.
