[0063] Embodiment 2

[0064] The same as embodiment 1 is not described, and the difference from embodiment 1 is that:

[0065] Please refer to Figure 1 , further comprising a storage tank, the storage tank stores a protective liquid, and the storage tank is provided with a delivery pump for delivering the protective liquid, a plurality of spray heads 4 are evenly distributed on the inner wall of the film coating arc plate 1, and the film coating arc plate 1 is provided with a spray groove in communication with the spray heads 4; the delivery pump is provided with a delivery pipe, and the delivery pipe is in communication with the spray groove at the extension end.

[0066] In the embodiment, all the hydraulic rods are electric hydraulic push rods, the storage tank is further provided with a storage battery for providing power, and a controller for controlling the movement of each electric hydraulic push rod and the driving motor.

[0067] The protective liquid is lime, which is a solution of lime powder mixed with water. Brushing lime on trees can kill bacteria and disinfect. In early winter, bacteria hide in the cracks of trees and cause harm to plants in the coming spring. Therefore, a solution of lime powder mixed with water can be used to prevent disease by applying it to the surface of the tree. Brushing lime on trees can prevent insect pests. In summer, there are more insects, so the probability of plant insect pests is higher. Using lime containing insect poison can reduce the probability of plant insect pests and also avoid animals gnawing trees. Applying lime to trees in winter can prevent frost damage. The daytime temperature in winter is usually around 10 degrees, and if the tree bark is dark, it will absorb light and heat, increasing the heat in the plant. The temperature at night is often below 0 degrees, so the tree trunk of the plant will crack due to the large difference between day and night temperatures.

[0068] In use, the embodiment of the present application:

[0069] Before the film 2 is wound and laid, the first hydraulic rod 33 is controlled to drive the rack 34 to move, so that the roller gear 3 can be rotated from horizontal to upwardly inclined, so that the film coating arc plate 1 can be spirally moved upward on the trunk through the angle change of the roller gear, and at the same time the driving motor is started to drive the roller gear to rotate, and the conveying pump is started to uniformly spray the protective liquid on the trunk, so that the film coating arc plate 1 can be periodically spirally moved up and down by controlling the inclined direction of the roller gear, and the protective liquid can be fully applied on the trunk, so as to ensure the protection effect of the protective liquid on the trunk.

[0070] After the spraying is completed, the automatic winding of the film 2 can be performed, and such design combines the spraying of the protective liquid and the winding of the film 2, so that the film coating arc plate 1 can spray the protective liquid and wind the film 2 on the trunk in sequence, improves the overall work efficiency, effectively reduces the labor intensity of workers, and improves the protection effect on the tree.

8. A forest pest control method characterized by, The method comprises the following steps: S1, the trunk is first encircled at the center position by the film arc plate, then the first fixed rod and the second fixed rod are controlled to be elongated, so that the rolling ball and the rolling gear are extruded and fixed between the trunk, and the film arc plate is fixed on the trunk; S2, then the third hydraulic rod is controlled, the extrusion plate is adsorbed by the suction cup, the film is driven to move towards the trunk, when the extrusion plate approaches the trunk, the trunk drives the transmission rod to move towards the transmission groove, the positioning rod is driven to move outward through hydraulic transmission, so that the positioning rod extrudes the positioning nails outward, and the positioning nails fix the film on the trunk, then the suction cup is controlled to separate the suction cup from the film, and the extrusion plate is separated from the trunk; S3, then the driving motor is driven to rotate the rolling gear, so that the film arc plate rotates around the trunk for a set number of turns, and the film can be wound in a ring shape on the trunk, then the first hydraulic rod is controlled to drive the rack to move, so that the rolling gear can be rotated from a horizontal state to an upwardly inclined state, so that the film arc plate can move upward on the trunk in a spiral shape, and the film can be wound on the trunk in a spiral shape; S4, after the spiral winding is completed, the first hydraulic rod is controlled to restore the rack to the initial position, and the rolling gear is restored to the horizontal state, so that the film can be wound in a ring shape on the upper end of the trunk, then the third hydraulic rod is controlled again, the extrusion plate is driven to move towards the trunk, and the film is fixed on the trunk by the positioning nails. S5 then restores the extrusion plate to the initial position through the third hydraulic rod, controls the roller gear to rotate by a certain angle, and moves the suction cup to the film outside the positioning nail, at this time, controls the third hydraulic rod to make the extrusion plate close to the film, starts the suction mechanism, and makes the suction cup adsorb the film. Since the film is in an inclined state, the transmission rod will not be pressed against the trunk when the suction cup adsorbs the film. Then, the cutting knife is controlled to extend, the inclined film is cut and separated by the cutting knife, and the automatic film covering of the trunk is realized.
