[0025] In the above technical solution, the liquid extraction pump 15 can be used to extract the paint in the material cylinder 14. The connecting pipe 12 can be used to connect the liquid extraction pump 15 and the connecting pipe 12 through a water pipe. The paint can be sprayed out through the spray nozzles 13 provided on the connecting pipe 12 to spray the trunk of the tree.

[0026] In the present utility model, the power assembly 3 includes a motor 301. The motor 301 is fixedly connected to the top of the mounting plate 201. The rotating shaft of the motor 301 passes through the arc-shaped plate 5 at the top of the inner arc surface of the mounting plate 201, and a gear 302 is provided at one end of the rotating shaft passing through the mounting plate 201.

[0027] In the above technical solution, by setting the motor 301, when the motor 301 rotates forward, it can drive the gear 302 arranged on the output shaft of the motor 301 to rotate. By setting the gear 302 meshing with the arc-shaped rack 9, the rotation of the gear 302 can drive the rack to move. The movement of the rack can drive the arc-shaped slider 7 at the top of the rack to slide toward the motor 301 in the arc-shaped through groove 6, and further drive the mounting frame 10 and the connecting pipe 12 fixed on the mounting to slide toward the motor 301 end in the arc-shaped sliding groove 11. When the liquid extraction pump 15 starts to work, the spraying mechanism 2 can spray half of the tree trunk.

[0028] In the present utility model, the auxiliary rotation assembly 4 includes a group of fixing plates 401, and the two fixing plates 401 are respectively fixedly connected to the centers of the top and bottom of the mounting plate 201. At one end of each fixing plate 401 close to the inner arc surface of the mounting plate 201, there is a connecting plate 402. At the end of the connecting plate 402 away from the fixing plate 401, there is an abutting plate 403. A group of through holes 404 are provided on the abutting plate 403, and telescopic columns 405 are respectively inserted into the through holes 404. One end of the telescopic column 405 close to the fixing plate 401 passes through the through hole 404, and a nut 406 is threadedly connected to the end of the telescopic column 405 passing through the through hole 404. The end of the telescopic column 405 away from the fixing plate 401 is fixedly connected to a U-shaped wheel frame 407. Auxiliary wheels 408 are rotatably connected to both ends of the U-shaped wheel frame 407. A spring 409 is sleeved on the telescopic column 405.

[0029] In the above technical solution, by arranging the auxiliary wheels 408 rotatably connected to both ends of the U-shaped wheel frame 407, after the motor 301 drives the nozzle 13 to move to the end of the motor 301, the mounting plate 201 can be rotated by operating the operating handle 18 along the spraying direction of the tree trunk, and the whole spraying mechanism 2 can be driven to rotate on the tree trunk, so as to spray the unsprayed half of the tree trunk.

[0030] The working principle of the tree whitening device for municipal gardens of the present utility model is as follows:

[0031] In use, first, push the flatbed cart 1 to a position near the tree to be sprayed. Then, pick up the spraying mechanism 2 by operating the operating handle 18. Align the inner arc surface of the semi-circular mounting plate 201 in the spraying mechanism 2 with the trunk part of the tree. Next, move the spraying mechanism 2 towards the trunk part so that the auxiliary wheels 408 in the auxiliary rotation assemblies 4 located at the top and bottom of the mounting plate 201 are both attached to the trunk. After that, start the liquid suction pump 15. The liquid suction pump 15 pumps out the paint in the paint barrel 14, transports it through the water pipe to the nozzle 13, and sprays it onto the trunk. (It should be noted that: between the liquid suction pump 15 and the paint barrel 14 and between the liquid suction pump 15 and the connecting pipe 12, they are always connected by a water pipe in the initial state.) Then, start the motor 301 to rotate forward. The forward rotation of the motor 301 drives the gear 302 to rotate. The rotation of the gear 302 can drive the rack to move. The movement of the rack can drive the arc-shaped slider 7 at the top of the rack to slide towards the motor 301 side in the arc-shaped through groove 6. Furthermore, it can drive the mounting frame 10 and the connecting pipe 12 fixed on the mounting to slide towards the motor 301 end in the arc-shaped sliding groove 11, so that the spraying mechanism 2 can spray half of the tree trunk. After the motor 301 drives the nozzle 13 to move to the motor 301 end and finishes spraying half of the tree trunk, rotate the mounting plate 201 along the spraying direction of the tree trunk by operating the operating handle 18. During this process, each auxiliary wheel 408 rotates on the trunk, which can drive the entire spraying mechanism 2 to rotate on the trunk, and then can spray the unsprayed half of the trunk. After the spraying is completed, first control the liquid suction pump 15 to stop rotating, and then control the motor 301 to rotate in reverse, so that the gear 302 drives the rack to rotate, and then the arc-shaped slider 7 slides towards the end far from the motor 301 in the arc-shaped through groove 6. When the arc-shaped slider 7 slides to the end of the arc-shaped through groove 6 far from the motor 301, the nozzle 13 returns to its original position, completing an entire spraying process.

[0032] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
