Description

Technical Field

[0001] This utility model relates to the field of agricultural pest and disease control equipment technology, specifically to a directional spraying device for the control of pests and diseases in chestnut trees. Background Technology

[0002] In chestnut tree cultivation, pest and disease control is a crucial aspect of ensuring chestnut yield and quality. Currently, traditional spraying methods mainly include manual backpack spraying and large-scale mechanical spraying. Manual backpack spraying has many drawbacks, such as high labor intensity and low work efficiency. Furthermore, due to the limited pump pressure of manual backpack spraying, it is difficult to ensure that the pesticide solution reaches the top of the chestnut trees, affecting the spraying effect and failing to meet the pest and disease control needs of large-scale chestnut forests.

[0003] While large-scale mechanical spraying improves work efficiency, it also suffers from low pesticide utilization and significant impact on the surrounding ecological environment because it cannot target specific areas of chestnut trees affected by pests and diseases. Furthermore, since chestnut trees are mostly planted in mountainous areas, mechanical spraying vehicles are difficult to move to these areas for spraying, affecting the effectiveness of the spraying. With the increasing awareness of agricultural product quality and safety and ecological environmental protection, there is an urgent need for a chestnut tree pest and disease control device that can achieve targeted spraying, improve pesticide utilization, and reduce labor intensity.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4This utility model provides a technical solution: a directional spraying device for the prevention and control of diseases and pests in chestnut trees, including a booster pump 1, a delivery pipe 11 fixedly installed at the outlet end of the booster pump 1, multiple hoses 13 connected to the delivery pipe 11, nozzles 14 installed at the ends of the hoses 13, a vertical rod 2 for support provided on one side of the hoses 13, a support 22 horizontally rotatably connected to the top of the vertical rod 2, the support 22 having its rotation angle limited by a first fastening bolt 232, a connecting rod 25 rotatably connected to the support 22 along the vertical direction, and nozzles 14 fixedly installed at the front end of the connecting rod 25. The rotation angle is limited between the supports 22 by the second fastening bolt 24. The inlet end of the booster pump 1 is fixedly installed with a suction pipe 10, which is connected to an external liquid storage container. The booster pump 1 draws liquid from the external liquid storage container through the suction pipe 10. After being pressurized, the liquid is transmitted to the nozzle 14 through the delivery pipe 11, connector pipe 12, and hose 13 and sprayed out. The booster pump 1 increases the liquid pressure, which solves the problem that the pressure of manual backpack sprayers is insufficient and it is difficult to spray to the top of the chestnut tree. At the same time, the setting of multiple hoses 13 and nozzles 14 can meet the needs of multi-directional spraying, improving spraying efficiency and coverage.

[0029] like Figure 1 As shown, multiple connector pipes 12 are fixedly installed on the delivery pipe 11, and the hose 13 is connected to the connector pipe 12 by a flange, which facilitates installation and disassembly.

[0030] like Figure 2 As shown, an insertion cone 201 is fixedly installed at the bottom of the vertical rod 2. The insertion cone 201 is conical, which allows it to be easily inserted into the ground. The vertical rod 2 is then stably positioned around the chestnut tree, allowing the nozzle 14 installed on the vertical rod 2 to spray the chestnut tree in a directional manner, effectively targeting the affected areas and improving pesticide utilization.

[0031] like Figure 2 As shown, the vertical rod 2 is equipped with multiple pipe clamps 20 arranged along the height direction of the vertical rod 2. The hose 13 is engaged with the pipe clamps 20 to limit the hose 13, prevent the hose 13 from shaking or tangling during the spraying process, ensure the stability of the liquid delivery, and facilitate the arrangement and storage of the hose 13.

[0032] like Figure 3As shown, a limiting plate 23 is fixedly installed at the bottom of the support 22. A protruding post 231 is fixedly installed at the center of the bottom surface of the limiting plate 23. The protruding post 231 is located inside the vertical rod 2 and is rotatably connected to the vertical rod 2. A perforated plate 21 is fixedly installed at the top of the vertical rod 2. The perforated plate 21 is provided with multiple limiting holes 211. The first fastening bolt 232 is threadedly connected to the limiting plate 23. The first fastening bolt 232 is inserted into the corresponding limiting hole 211. The support 22 can be horizontally rotated to adjust its orientation. After adjustment, the rotation angle of the support 22 is limited by the insertion and engagement of the first fastening bolt 232 with the limiting hole 211 of the perforated plate 21, so as to achieve precise positioning of the nozzle 14 in the horizontal direction and meet the spraying needs of different directions.

[0033] like Figure 3 and Figure 4 As shown, a U-shaped groove 221 is provided inside the support 22. The end plate of the connecting rod 25 is located inside the U-shaped groove 221 and is rotatably connected to the left and right sides of the groove 221 via a rotating shaft. Multiple insertion holes 251 are provided on the end plate of the connecting rod 25. The second fastening bolt 24 is threadedly connected to the support 22 and is inserted into the insertion hole 251. This allows the end of the connecting rod 25 to rotate within the U-shaped groove 221 to adjust the pitch angle of the nozzle 14. After adjustment, the second fastening bolt 24 is inserted into the insertion hole 251 to restrict the rotation of the connecting rod 25, thus fixing the angle of the nozzle 14 in the vertical direction. Combined with horizontal adjustment, the orientation of the nozzle 14 can be precisely controlled, enabling directional spraying of pesticides on the diseased and pest-infested parts of the chestnut tree.

[0034] It is worth noting that a handle 26 is also fixedly installed at the end of the connecting rod 25, and a handle 27 is fixedly installed at the end of the handle 26. This allows the operator to easily rotate the connecting rod 25 to adjust the angle of the nozzle 14 by holding the handle 27 and using the handle 26. This makes the operation more labor-saving and convenient, and improves the flexibility and efficiency of the spraying operation.

[0035] In this embodiment, the outer diameter of the limiting disk 23 is larger than the outer diameter of the perforated disk 21, so that the limiting disk 23 can provide waterproof protection by blocking the upper part, thus achieving waterproof protection for the lower protruding post 231.

[0036] Finally, it should be noted that the booster pump 1, external power supply and corresponding control system involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0037] When using the directional spraying device for the prevention and control of diseases and pests of chestnut trees, first connect the suction pipe 10 to the external liquid storage container, insert the insertion cone 201 at the bottom of the vertical rod 2 into the ground around the chestnut tree, so that the nozzle 14 is in a suitable spraying position to prepare for spraying. Then, hold the handle 27 and drive the connecting rod 25 through the handle rod 26. Using the U-shaped groove 221 and the rotating shaft in the support 22, roughly adjust the nozzle 14 to a suitable pitch angle. Then, tighten the second fastening bolt 24 into the insertion hole 251 to fix the connecting rod 25. Next, rotate the limiting plate 23 to drive the support 22 to rotate horizontally on the vertical rod 2 to adjust the position of the nozzle 14. After determining the position, tighten the first fastening bolt 232 into the limiting hole 211 of the perforated plate 21 to complete the fixation of the nozzle 14 angle.

[0038] Then, use pipe clamp 20 to fix hose 13 to vertical pole 2 to prevent hose from shaking. Start booster pump 1. The liquid medicine is sucked in from suction pipe 10, pressurized and then sprayed out from nozzle 14 through delivery pipe 11, connector pipe 12 and hose 13 to spray the diseased and pest-infested parts of chestnut tree. During the spraying process, with personnel wearing protective clothing, the angle of nozzle 14 can be finely adjusted at any time by handle 27 to achieve better spraying effect.
