Description

Technical Field

[0001] This utility model relates to the technical field of fruit tree pest control equipment, specifically a pesticide application device for fruit trees. Background Technology

[0002] Fruit trees are highly susceptible to pests such as aphids, fruit borers, and spider mites during the critical stages of growth, flowering, and fruiting. These pests cause leaves to curl and fall off, and fruits to become deformed and rotten by feeding on leaves, boring into fruits, or sucking sap. This can result in yield losses of 30%-50% and a decrease in commercial value, or even cause the entire tree to wither and die. To combat these pests, traditional orchards generally rely on manual spraying using 15-20 liter plunger sprayers carried on the back.

[0003] However, for tall fruit trees such as apples and citrus trees that are over 4 meters tall, the vertical spraying height of traditional backpack sprayers is usually less than 2.5 meters, which can only cover the middle and lower layers of the canopy. Meanwhile, more than 70% of aphids gather at the top of the new shoots, forcing fruit farmers to climb bamboo ladders or cut branches to spray again. This increases the safety risks of falling from heights and pesticide poisoning, and the repeated trampling damages the soil structure of the orchard. Therefore, we propose a new type of pesticide application device for fruit trees. Utility Model Content

[0021] This utility model provides a technical solution:

[0022] Please see Figures 1-5 A pesticide application device for fruit trees, characterized in that it includes a tree hoop 1 and a fastening rod 2 threadedly connected to the tree hoop 1, and the tree hoop 1 is provided with a pesticide application structure 3.

[0023] The application structure 3 includes a V-block 301 fixedly installed on the tree hoop 1, a rotating component 302 fixedly installed on the V-block 301, a horizontal adjustment component 303 provided on the rotating component 302, a spraying component 304 fixedly installed on the horizontal adjustment component 303, and a vertical adjustment component 305 provided on the spraying component 304.

[0024] The application structure 3 is fixed to the tree hoop 1 by the V-block 301. The rotating component 302 drives the lateral adjustment component 303 to rotate circumferentially. The lateral adjustment component 303 extends to adjust the lateral coverage of the spraying component 304. The spraying component 304 draws pesticide through the water pump 3043 and sprays it through the atomizing nozzle 3046. At the same time, the vertical adjustment component 305 can adjust the spraying height to cover the top of the fruit tree. This structure realizes precise application of pesticides to the fruit tree in all directions and at multiple levels, effectively solving the problems of uneven spraying and blind spots in traditional equipment, significantly improving pest control efficiency and operational safety, while reducing pesticide usage and the risk of poisoning.

[0025] Please see Figure 1 , Figure 2 and Figure 5 The rotating assembly 302 includes a servo motor 3021 fixedly mounted on the V block 301, and a rotating rod 3022 fixedly mounted on the output end of the servo motor 3021. The rotating assembly 302 also includes a housing 3023 fixedly mounted on the tree hoop 1. The rotating rod 3022 passes through the housing 3023. A drive gear 3024 is fixedly mounted on the top end of the rotating rod 3022. A driven gear 3025 meshes with the outer side of the drive gear 3024. An arc-shaped groove is provided at the bottom of the housing 3023. A linkage rod 3026 adapted to the arc-shaped groove is fixedly mounted on the driven gear 3025.

[0026] The rotating component 302 is driven by the servo motor 3021 to rotate the rotating rod 3022, which in turn drives the drive gear 3024 to rotate. The drive gear 3024 meshes with the driven gear 3025 to rotate, and the linkage rod 3026 on the driven gear 3025 swings regularly in the arc-shaped groove at the bottom of the casing 3023. This component realizes the circumferential rotational spraying of the spraying component 304. The gear transmission ensures the stability and accuracy of the rotation. Combined with the arc-shaped groove limiting, the liquid can be evenly covered in all directions of the fruit tree. It effectively solves the problem that the top of the canopy and hidden parts are difficult to reach by traditional manual spraying, and significantly improves the efficiency and effect of pest control.

[0027] Please see Figure 1 , Figure 2 and Figure 4 The lateral adjustment assembly 303 includes a hollow crossbar 3031 fixedly installed at the lower end of the linkage rod 3026. A lateral electric telescopic rod 3032 is fixedly installed in the inner cavity of the hollow crossbar 3031, and a movable rod 3033 is fixedly installed at the output end of the lateral electric telescopic rod 3032. A limiting groove is symmetrically opened on the hollow crossbar 3031, and a slider is symmetrically installed on the outer side of the movable rod 3033. The slider is adapted to the limiting groove and is located in the limiting groove.

[0028] The lateral adjustment component 303 drives the hollow crossbar 3031 through the linkage rod 3026. The lateral electric telescopic rod 3032 inside the hollow crossbar 3031 drives the movable rod 3033 to extend and retract horizontally along the limiting slide groove. The slider slides in the limiting slide groove to ensure smooth extension and retraction, so as to adapt to the lateral diffusion distance of different fruit tree branches and leaves. This component realizes the flexible adjustment of the horizontal position of the spraying component 304, ensuring that the liquid can cover the entire lateral area of ​​the fruit tree canopy, and achieves all-round spraying in conjunction with the rotating component 302.

[0029] Please see Figure 1 , Figure 2 and Figure 3 The spraying assembly 304 includes a medicine placement box 3041 fixedly installed at the end of the movable rod 3033 away from the transverse electric telescopic rod 3032. A medicine tank 3042 is movably installed in the inner cavity of the medicine placement box 3041. A water pump 3043 is fixedly installed at the center of the top of the medicine tank 3042. The liquid extraction end of the water pump 3043 is located at the bottom of the inner cavity of the medicine tank 3042. A retractable rubber hose 3044 is fixedly installed at the liquid outlet end of the water pump 3043. A liquid distribution plate 3045 communicating with the inner cavity of the retractable rubber hose 3044 is fixedly installed at the liquid outlet end of the retractable rubber hose 3044. A plurality of atomizing nozzles 3046 are fixedly installed on the liquid distribution plate 3045.

[0030] The spraying assembly 304 supports the pesticide placement box 3041 via a movable rod 3033. The water pump 3043 in the pesticide tank 3042 draws the pesticide solution, which is then transported to the distribution plate 3045 via a retractable rubber hose 3044. Finally, the pesticide mist is sprayed out by the atomizing nozzle 3046 to achieve the spraying function. As the core execution component, this assembly pressurizes the pesticide solution through the water pump 3043 and refines it through the atomizing nozzle 3046. In conjunction with the rotating assembly 302 and the lateral adjustment assembly 303, the pesticide solution is evenly distributed over the fruit tree canopy. This effectively solves the problems of uneven pesticide deposition and incomplete coverage in traditional spraying methods, significantly improving the pest control effect and operational efficiency, while reducing pesticide waste and environmental pollution risks.

[0031] Please see Figure 1 and Figure 2 The vertical adjustment assembly 305 includes a vertical electric telescopic rod 3051 fixedly installed on the medicine placement box 3041. An L block 3052 is fixedly installed at the output end of the vertical electric telescopic rod 3051, and the L block 3052 is fixedly connected to the dispensing plate 3045.

[0032] The vertical adjustment component 305 drives the L block 3052 to adjust the height of the liquid distribution plate 3045 in the vertical direction through the extension and retraction of the vertical electric telescopic rod 3051, thereby changing the spraying height of the atomizing nozzle 3046. This component effectively solves the problem that traditional spraying equipment has difficulty reaching the new shoots at the top of fruit trees. By precisely controlling the spraying height, it ensures that the pesticide can evenly cover all growth levels of the fruit trees, significantly improving the comprehensiveness and effectiveness of pest control operations.

[0033] In practical use, the working principle of this utility model is as follows:

[0034] When using this fruit tree pesticide application device, the operator first places the tree hoop 1 at the designated height on the main trunk of the fruit tree. Then, by rotating the fastening rod 2, the device is secured to the tree trunk, avoiding the operational risks associated with traditional backpack sprayers that require manual climbing. After securing, the lateral adjustment component 303 is activated. The lateral electric telescopic rod 3032 inside the hollow crossbar 3031 drives the movable rod 3033 to extend outward, ensuring that the total length of the end of the movable rod 3033 and the hollow crossbar 3031 exceeds the maximum transverse diameter of the tree crown by 10-15%.

[0035] Once the lateral adjustment is in place, the rotating component 302 begins to operate. The servo motor 3021 drives the drive gear 3024 to rotate via the rotating rod 3022. The rotation of the drive gear 3024 drives the driven gear 3025 to rotate. The rotation of the driven gear 3025 drives the linkage rod 3026 to rotate. The linkage rod 3026, under the limit of the arc groove, realizes the regular oscillating spraying of the spraying component 304. The rotation of the linkage rod 3026 drives the lateral adjustment component 303 to rotate, and simultaneously starts the spraying component 304 to spray pesticides during the rotation process. At this time, the water pump 3043 draws pesticide liquid from the pesticide tank 3042 and delivers it to the distribution plate 3045 through the retractable rubber hose 3044. The pesticide mist is sprayed out through the atomizing nozzle 3046. Combined with the centrifugal atomization effect generated by the rotating component 302, the pesticide particles penetrate the gaps between branches and leaves under the action of centrifugal force.

[0036] For the hidden parts at the top of the tree canopy, the vertical electric telescopic rod 3051 of the vertical adjustment component 305 can lift the liquid distribution plate 3045 to a height of 4.5 meters above the ground, and together with the atomizing nozzle 3046, accurately cover the growth points of the new shoots at the top of the fruit tree that are difficult to reach by traditional methods.

[0037] To address the coverage blind spots inherent in single-point fixed spraying, after the initial spraying, a quick-release mechanism moves the tree hoop to a position 180° opposite the trunk, and all the above operations are repeated to achieve grid-like coverage of the tree canopy in three dimensions. Compared to traditional manual respraying, this dual-position operation method improves the uniformity of pesticide deposition, avoids prolonged exposure of operators to pesticides, and shortens the application time per fruit tree. It significantly improves the core pain points of existing technologies, such as difficulties in working at heights and low efficiency of repeated spraying.

[0038] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
