Two spraying parts are symmetrically arranged at one end of the adjusting bracket 3 far away from the lifting fixing plate 6. An adjusting part for angle adjustment is arranged between the two spraying parts and the adjusting bracket 3 for adjusting the angle to form an annular spray on the tree.

[0024] During specific implementation, in the actual spraying process of apple tree canker disease, usually, a spraying device is held manually to atomize and spray the outside of the fruit tree, and it is necessary for the operator to move around the fruit tree to spray the outside of the fruit tree comprehensively to achieve the treatment effect. When spraying, only one side can be sprayed each time, and the operator needs to move around the tree to spray the tree comprehensively. First, it affects the spraying efficiency. Second, it cannot achieve a comprehensive and uniform spraying on the fruit tree and cannot comprehensively treat the fruit tree. Therefore, in this solution, spraying parts are arranged at one end of the adjusting bracket 3, and the opening and closing angles of the two spraying parts are adjusted through the adjusting part, so that the two spraying parts form an annular sleeve on the fruit tree, and the fruit tree is sleeved between the two spraying parts, thereby achieving a comprehensive spray on the fruit tree. And in cooperation with the lifting part, the spraying parts move from bottom to top to achieve a uniform spray on the outside of the fruit tree;

[0025] And in this solution, a rotating motor 7 is arranged between the adjusting bracket 3 and the lifting fixing plate 6. When spraying the tree trunk, the rotating motor 7 can be started, and the rotating motor 7 drives the adjusting bracket 3 to rotate upward, so that the two spraying parts form an annular spray on the tree trunk.

[0026] In this embodiment: The spraying part includes an arc-shaped spraying pipe 8. One end of the arc-shaped spraying pipe 8 close to the adjusting bracket 3 is fixedly connected with a rotating shaft 10. The rotating shaft 10 penetrates through the adjusting bracket 3 and is rotatably connected with the adjusting bracket 3. A plurality of atomizing nozzles 9 for atomizing spraying are arranged inside the arc-shaped spraying pipe 8. The arc-shaped spraying pipe 8 is arranged to be hollow inside.

[0027] The adjusting member includes a hydraulic telescopic rod 13 fixedly connected to the bottom of the adjustment bracket 3. The telescopic end of the hydraulic telescopic rod 13 is fixedly connected with a transmission rack 12. A transmission gear 11 is fixedly connected to the outside of the rotating shaft 10, and the transmission gear 11 is meshed and connected with the transmission rack 12.

[0028] One end of each of the two arc-shaped spray pipes 8 is fixedly communicated with a branch pipe 19 between the medicine storage barrels 2 for supplying liquid medicine to the arc-shaped spray pipes 8.

[0029] During specific implementation, when a water pump is arranged inside the medicine storage barrel 2, the water pump conveys the liquid medicine into the two arc-shaped spray pipes 8 through the branch pipe 19, and then spray treatment is carried out through the atomizing nozzles 9 arranged inside the arc-shaped spray pipes 8. When it is necessary to adjust the opening and closing angles of the two arc-shaped spray pipes 8, by starting the hydraulic telescopic rod 13, the telescopic end of the hydraulic telescopic rod 13 drives the fixedly connected transmission rack 12 to move, the transmission rack 12 drives the meshed and connected transmission gear 11 to rotate, and further the transmission gear 11 can drive the rotating shaft 10 to rotate, so that the arc-shaped spray pipes 8 deflect, and the opening and closing angles of the two arc-shaped spray pipes 8 can be adjusted according to fruit trees of different sizes, and different sizes of fruit trees can be adapted for adjustment.

[0030] In this embodiment: it includes a lifting lead screw 5. The lifting lead screw 5 is arranged inside the fixed frame 4 and is rotationally connected with the fixed frame 4. The lifting lead screw 5 penetrates through the lifting fixing plate 6 and is connected with the lifting fixing plate 6 through a ball screw pair. A servo motor is fixedly connected to the top of the fixed frame 4, and the output shaft of the servo motor is fixedly connected with the lifting lead screw 5.

[0031] During specific implementation, by starting the servo motor, the servo motor drives the lifting lead screw 5 to rotate, and further the lifting fixing plate 6 is lifted and lowered.

[0033] Specifically, during the spraying process of fruit trees, there are a large number of dead wood shells on the surface of the fruit trees. If the medicine is sprayed on the surface of the tree shell, the medicine cannot effectively treat the fruit trees. At the same time, when spraying the tree trunk, there will be a large number of leaves on the outside. Therefore, in this solution, a toggle rope 14 is set between the two ends of the top of the two arc-shaped spray pipes 8. When the arc-shaped spray pipe 8 rises to spray, the toggle rope 14 first contacts the tree trunk. If it is a dead tree shell, the diseased tree shell will be glassed. Since the diseased tree shell is dead, it is easy to separate. In addition, in this solution, a winding drum 15 is set at one end of the toggle rope 14. When encountering an obstacle, the toggle rope 14 can pull the winding drum 15 to rotate, so that the toggle rope 14 wrapped around the outside of the winding drum 15 can be released. At the same time, when spraying the tree trunk, the branches can also be toggled to avoid affecting the spraying.
