[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a whitewashing device for seedling maintenance includes two spray sleeves 1, a positioning assembly 2 is installed inside the spray sleeve 1, the positioning assembly 2 includes a ring tube 4, the ring tube 4 is fixedly installed on the inner wall of the spray sleeve 1, three nozzles 5 are installed on the inner ring of the ring tube 4, three rollers 6 are movably installed on the upper and lower ends of the inner wall of the spray sleeve 1, a connecting pipe 7 is connected to the top of the ring tube 4, a grip rod 8 is movably installed on the outer ring of the spray sleeve 1, and a delivery pipe 9 is installed on the top of the grip rod 8 and connected to the connecting pipe 7.

[0022] In this embodiment, the top view of the spray sleeve 1 is in the shape of a semicircle, and the two spray sleeves 1 are symmetrically arranged. The two spray sleeves 1 are sleeved on the periphery of the seedlings to fully spray the white material.

[0023] In this embodiment, the nozzle 5 and the roller 6 are both installed in a ring-shaped manner. The roller 6 is located in the inner circle of the spray sleeve 1 and is movably rotated. When the spray sleeve 1 slides up and down around the seedlings for spraying, it is supported by the rotation of the roller 6.

[0024] In this embodiment, the connecting pipe 7 and the rear end of the delivery pipe 9 are connected to each other, and the front end of the delivery pipe 9 is used to connect to the spray liquid box. The paint is transported to the ring pipe 4 through the circulation pump in the spray liquid box, and sprayed out through the nozzle 5 to spray the surface of the seedlings.

[0025] In this embodiment, a rotating assembly 3 is installed between the outer side of the spray sleeve 1 and the handle 8. The rotating assembly 3 includes a rotating shaft 10 and a movable sleeve 11. The rotating shaft 10 is fixedly installed on the outer side of the spray sleeve 1, and the movable sleeve 11 is fixedly installed at the rear end of the handle 8 and is sleeved on the outside of the rotating shaft 10. A spring 12 is installed between the outer periphery of the rotating shaft 10 and the movable sleeve 11. An arc groove 13 is provided on the inner wall of the movable sleeve 11. A fixed block 14 is installed on the outer periphery of the rotating shaft 10 and in the arc groove 13. Through the rotation of the rotating shaft 10, the spray sleeve 1 is located inside the handle 8 and rotates, which facilitates the spray sleeve 1 to maintain balance when spraying in the upper and lower positions.

[0026] In this embodiment, the movable sleeve 11 is sleeved on the outside of the rotating shaft 10 and is arranged to rotate movably. The two ends of the spring 12 are respectively connected to the inner walls of the rotating shaft 10 and the movable sleeve 11. Under the action of the spring 12, the rotating shaft 10 drives the spray sleeve 1 to rotate, and the spray sleeve 1 automatically rotates back to its position after spraying is completed.

[0027] In this embodiment, the fixed block 14 is fixedly installed with the rotating shaft 10 and is slidably arranged in the arc groove 13. The fixed block 14 rotates with the rotating shaft 10 and stops automatically when it rotates to a specified angle through the arc groove 13.

[0028] It should be noted that the utility model is a whitening device for seedling maintenance. When in use, the front end of the delivery pipe 9 is connected to the circulation pump in the spray liquid box, and the spray liquid of the spray liquid box is delivered to the delivery pipe 9 through the circulation pump. When spraying the seedlings, the two spray sleeves 1 are located on the periphery of the seedlings, and the paint is delivered to the annular tube 4 and sprayed out through the nozzle 5 to evenly spray the paint onto the surface of the seedlings. The spray sleeve 1 is slid downward, and the roller 6 rotates in contact with the surface of the seedlings to provide support. When the spray sleeve 1 slides downward, the grip 8 is tilted, and the rotation of the rotating shaft 10 ensures that the spray sleeve 1 is always sprayed perpendicular to the seedlings. After the spraying is completed, the two spray sleeves 1 are taken out, and the spray sleeve 1 is rotated under the action of the spring 12. The fixed block 14 is located in the arc groove 13 and slides to the specified position to stop the spray sleeve 1 from rotating, and then the spray sleeve 1 automatically rotates back to its position for the next spraying.
