[0025] One end of the rotating rod 23 close to the sealing chamber 26 is fixedly connected to the disc 22, and the support rod 21 is fixedly connected to the disc 22. The movable plug 28 is arranged in a convex shape, and the upper end of the movable plug 28 is slidably connected in the opening. When the support rod 21 moves in a circular motion, it can intermittently push the movable plug 28 to move right in the sealing chamber 26.
[0026] A square cavity 2 is fixedly connected to the vehicle body 1, one end of which is connected to the telescopic cavity 32, an arc cavity 3 is fixedly connected to the square cavity 2, a rotating shaft 15 is rotatably connected in the arc cavity 3, and a fan blade 16 is installed on the outer surface of the rotating shaft 15 in a ring array. When the medicine passes through the square cavity 2, it will push the fan blade 16 and drive the rotating shaft 15 to rotate. An elliptical cavity 4 is fixedly connected to one side of the arc cavity 3, and a piston plate 17 is slidably connected in the elliptical cavity 4. The end of the rotating shaft 15 away from the fan blade 16 passes through the elliptical cavity 4 and is threadedly connected to the piston plate 17. When the rotating shaft 15 moves, it can drive the piston plate 1 7 moves, an airbag 34 is fixedly connected in the spraying chamber 7, one end of the spraying chamber 7 is fixedly connected to the spraying port 33, the airbag 34 is located on one side of the spraying port 33, an air release pipe 35 is fixedly connected to the airbag 34, an exhaust chamber 18 is fixedly connected between the elliptical chamber 4 and the airbag 34, the amount of gas input into the exhaust chamber 18 into the airbag 34 is greater than the amount discharged by the air release pipe 35, so the airbag 34 will expand, and then no longer enter the airbag 34 through the exhaust chamber 18, the gas in the airbag 34 will be slowly discharged through the air release pipe 35 until the airbag 34 is reset and the spraying port 33 is no longer closed.
[0027] In the present invention, when in use, the hydraulic pump 19 is first used to absorb the medicine in the water storage chamber 8 and discharge it into the telescopic chamber 32 through the square chamber 2. When the medicine passes through the square chamber 2, it will push the fan blades 16 in the arc chamber 3 and drive the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 can drive the piston plate 17 to move horizontally in the elliptical chamber 4, and squeeze the gas in the elliptical chamber 4 into the air bag 34 through the exhaust chamber 18. As the gas in the air bag 34 increases rapidly, it expands and closes the spray port 33 on one side. At this time, as more and more gas enters the telescopic chamber 32, the telescopic chamber 32 can be pushed to expand, and the spray chamber 7 can be pushed up to be flush with the tree top. At the same time, when the spray chamber 7 moves up, one end of the shielding cloth 6 can be pulled up. When the shielding cloth 6 is pulled, it can drive the winding roller 14 to rotate clockwise, and drive the rack plate 13 to move to the left, while compressing the first spring 10.
[0028] When the spraying chamber 7 is flush with the tree top, the hydraulic pump 19 is turned off. At this time, the medicine in the water storage chamber 8 no longer flows into the telescopic chamber 32, and the fan blades 16 and the rotating shaft 15 no longer rotate. After the gas in the airbag 34 is slowly discharged through the vent pipe 35, the airbag 34 shrinks and resets, and the spraying port 33 is no longer sealed. The rack plate 13 resets and moves under the pulling force of the first spring 10, which can drive the winding roller 14 to reset and rotate, and wind the shielding cloth 6 again. When winding the shielding cloth 6, the spraying chamber 7 can be pulled down, and the telescopic chamber 32 is compressed at the same time. After the telescopic chamber 32 is compressed, the medicine inside is squeezed through the spraying port on the spraying chamber 7. 33 is sprayed onto the tree trunk, so that the spraying chamber 7 starts spraying at the same level as the tree top. During the descent of the spraying chamber 7, it can continuously, evenly and vertically spray on the tree. After the telescopic chamber 32 is completely contracted, the spraying chamber 7 will also move down to the bottom of the tree, and can also spray an appropriate amount of medicine according to the height of the tree, avoiding excessive or insufficient spraying of the medicine during manual spraying, which affects the therapeutic effect on pests and trees. At the same time, during the descent of the spraying chamber 7, if the external wind blows the atomized medicine to a place where the staff is, the shielding cloth 6 shields the sprayed medicine to avoid the medicine adhering to the staff and causing harm.
[0029] Before the spray chamber 7 descends, the magnetic block 25 is first pulled. At this time, the magnetic block 25 slides in the rotating rod 23 and no longer adsorbs the moving plate 24. At this time, the moving plate 24 located at the lower side of the roller 20 slides downward under its own gravity and engages with the rack plate 13. The rack plate 13 moves to the right under the push of the first spring 10, and can drive the roller 20 and the rotating rod 23 to rotate when resetting. When the disc 22 and the support rod 21 rotate with the rotating rod 23, the support rod 21 moves in a circular motion and pushes the moving plug 28 in the sealing chamber. 26, and compresses the second spring 30. When the movable plug 28 moves to the right in the sealing chamber 26, the one-way valve on the air inlet pipe 31 is closed, and the one-way valve on the air supply pipe 29 is opened. The movable plug 28 can pressurize the gas in the sealing chamber 26 to enter the telescopic chamber 32 through the air supply pipe 29, and has a disturbing effect on the medicine in the telescopic chamber 32, forming bubbles moving from bottom to top, avoiding the precipitation of medicine in the medicine in the telescopic chamber 32, making the sprayed medicine mixture more uniform, which is beneficial to the control of tree pests.
[0030] When the support rod 21 pushes the movable plug 28 to move to the right to a certain distance, as the support rod 21 continues to rotate and no longer pushes the movable plug 28, the movable plug 28 moves to the left and resets under the push of the second spring 30. When the movable plug 28 moves to the right in the sealed chamber 26, the one-way valve at the connection between the left end of the sealed chamber 26 and the water tank opens, and the water in the water tank can enter the sealed chamber 26 and is located on the left side of the movable plug 28. When the movable plug 28 moves to the left in the sealed chamber 26, the one-way valve at the connection between the left end of the sealed chamber 26 and the water tank is closed, and the connecting pipe When the one-way valve on 5 is opened, the movable plug 28 can squeeze the water in the sealing chamber 26 to flow into the mounting seat 39 through the connecting pipe 5, and spray the water on the cleaning roller 38 through the water nozzle, so as to clean the cleaning roller 38. When the winding roller 14 rotates to reel in the shielding cloth 6, the rotation of the winding roller 14 can drive the cleaning roller 38 to rotate through the transmission belt 36. The cleaning roller 38 is on one side of the shielding cloth 6. The rotation of the cleaning roller 38 can tilt the surface of the shielding cloth 6, so that the shielding cloth 6 can remain clean when entering the storage chamber 37.
