[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] like Figure 1-4 As shown, this utility model provides an insect-proof device for tea cultivation, including a protective net structure 1 and an insect-repelling device 2 installed within the protective net structure 1. The protective net structure 1 includes a side net planted in the tea garden and surrounding the tea trees, and a top net that seals the top of the side net. The side net is connected to a support rod 3 planted vertically in the tea garden. The insect-repelling device 2 is installed on a fixed frame 4 fixedly set on the upper part of the side net. The insect-repelling device 2 includes a horizontal moving rod 21, a lifting mechanism 22, and an insect-repelling roller 23. The two ends of the horizontal moving rod 21 are slidably installed in the sliding grooves I41 set on the inner walls of both sides of the fixed frame 4, and are threadedly connected to the screw rods I42 installed at both ends of the fixed frame 4 parallel to the sliding grooves I41. The lifting mechanism 22 is movably installed at the bottom of the horizontal moving rod 21, and the insect-repelling roller 23 is rotatably installed at the lower end of the lifting mechanism 22. This invention utilizes a protective net structure 1 to block some larger pests from entering the tea garden, preventing damage to the tea leaves. Simultaneously, an insect-repelling roller 23 within the protective net structure 1 beats the tea leaves, dislodging small pests attached to them. The insect-repelling roller 23 can move laterally and longitudinally between tea bushes via an insect-repelling device 2. The rotation of the lead screw Ⅰ 42 drives the lateral moving rod 21 to move laterally within the slide groove Ⅰ 41, thus moving the insect-repelling roller 23 laterally. The lifting mechanism 22 moves longitudinally along the lateral moving rod 21. This causes the insect-repelling roller 23 to move longitudinally, and the lifting mechanism 22 causes the insect-repelling roller 23 to move up and down. When repelling pests on tea trees, the lifting mechanism 22 drives the insect-repelling roller 23 to move downward between the tea trees. Then, through the lateral and longitudinal movement of the insect-repelling device 2, the insect-repelling roller 23 moves between the tea trees, beating the tea leaves and knocking the pests off, thus preventing the pests from damaging the tea leaves. By using this device to control pests, it is possible to avoid spraying too much pesticide on the tea leaves, which would pollute the tea leaves and the soil, thereby improving the quality and safety of the tea.

[0019] The insect-repelling roller 23 has elastic plastic rods 231 evenly arranged on its side wall. When the insect-repelling roller 23 rotates, it drives the elastic plastic rods 231 to rotate and beat the tea leaves, which is more effective in knocking off the pests on the tea leaves and improving the quality and efficiency of insect prevention.

[0020] The side netting is equipped with a door 5 for easy access by workers. The door 5, which can be opened and closed, allows workers to easily enter the protective netting structure 1 to carry out their work.

[0021] The lead screw I42 is connected to the motor I43 installed at the end of the fixed frame 4. The motor I43 drives the lead screw I42 to rotate, thereby driving the transverse moving rod 21 to move laterally in the slide groove I41, which in turn drives the insect repelling roller 23 to move laterally to beat the tea leaves and knock off the pests.

[0022] The bottom of the transverse moving rod 21 is provided with a sliding groove II 211 to facilitate the sliding installation of the upper end of the lifting mechanism 22. A lead screw II 212, which is threadedly connected to the upper end of the lifting mechanism 22, is rotatably installed in the sliding groove II 211. The lead screw II 212 is driven by a motor II 213 installed at the end of the sliding groove II 211. The motor II 213 drives the lead screw II 212 to rotate, thereby driving the lifting mechanism 22 to move in the sliding groove II 211, which in turn drives the drive roller to move and beat the tea leaves, knocking off pests.

[0023] The lifting mechanism 22 includes a slider 221, a mounting frame I 222, a fixing sleeve 223, a lifting rod 224, a lead screw III 225, and a motor III 226. The slider 221 is slidably installed in the slide groove II 211 and threadedly connected to the lead screw II 212. The mounting frame I 222 is connected to the bottom of the slider 221, and the fixing sleeve 223 is connected to the bottom of the mounting frame I 222. The lifting rod 224 is telescopically installed in the fixing sleeve 223 and threadedly connected to the lead screw III 225 installed in the fixing sleeve 223. The lead screw III 225 is drively connected to the motor III 226 installed in the mounting frame I 222. The insect repellent roller 23 is rotatably installed at the lower end of the lifting rod 224. Motor III226 drives lead screw III225 to rotate, driving lifting rod 224 to move up and down in fixed sleeve 223, thereby driving insect repelling roller 23 to move up and down. When it is necessary to drive away pests on tea leaves, insect repelling roller 23 is lowered and moved between tea trees to pat the tea leaves. After the insect repelling is completed, insect repelling roller 23 is raised to carry out tea picking and watering.

[0024] The lower end of the lifting rod 224 is connected to the mounting frame II 6, and the lower end of the mounting frame II 6 is rotatably connected to the insect-repelling roller 23. The insect-repelling roller 23 is connected to the motor IV 7 installed in the mounting frame II 6. The motor IV 7 drives the insect-repelling roller 23 to rotate, and the elastic plastic rod 231 on the insect-repelling roller 23 rotates to beat the tea leaves, thereby knocking off the pests on the tea leaves.

[0025] Work process:

[0026] This invention utilizes a protective net structure 1 to block some larger pests from entering the tea garden, preventing damage to the tea leaves. Simultaneously, an insect-repelling roller 23 within the protective net structure 1 beats the tea leaves, dislodging small pests attached to them. The insect-repelling roller 23 can move laterally and longitudinally between tea bushes via an insect-repelling device 2. The rotation of the lead screw Ⅰ 42 drives the lateral moving rod 21 to move laterally within the slide groove Ⅰ 41, thus moving the insect-repelling roller 23 laterally. The lifting mechanism 22 moves longitudinally along the lateral moving rod 21. This causes the insect-repelling roller 23 to move longitudinally, and the lifting mechanism 22 causes the insect-repelling roller 23 to move up and down. When repelling pests on tea trees, the lifting mechanism 22 drives the insect-repelling roller 23 to move downward between the tea trees. Then, through the lateral and longitudinal movement of the insect-repelling device 2, the insect-repelling roller 23 moves between the tea trees, beating the tea leaves and knocking the pests off, thus preventing the pests from damaging the tea leaves. By using this device to control pests, it is possible to avoid spraying too much pesticide on the tea leaves, which would pollute the tea leaves and the soil, thereby improving the quality and safety of the tea.

[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
