Description

Technical Field

[0001] This utility model relates to the field of fruit tree disease and pest control technology, and in particular to a spraying device for fruit tree disease and pest control. Background Technology

[0002] With the development of agricultural modernization, fruit tree cultivation, as an important component of agricultural production, directly impacts farmers' economic income and social food security through its yield and quality. However, the occurrence of pests and diseases is one of the main factors affecting the healthy growth of fruit trees. Effective pest and disease control can not only reduce economic losses but also ensure fruit quality; therefore, researching and developing efficient pest and disease control methods is of great significance.

[0003] Among existing fruit tree pest and disease control measures, chemical control remains one of the most commonly used methods. Traditional chemical control methods mainly rely on manual spraying. While this method is direct, it has several shortcomings due to the limitations of manual operation. First, manual spraying is relatively inefficient, especially in large-scale orchards, requiring a significant investment of manpower and time. Second, due to human height limitations, it is often difficult to cover the higher branches and leaves of fruit trees, causing these areas to become breeding grounds for pests and diseases, thus affecting the overall control effect.

[0004] To address these issues, drone spraying technology has been gradually introduced into the field of fruit tree pest and disease control in recent years. Drone spraying offers advantages such as a wide operating range and high flexibility, enabling large-scale pesticide spraying to be completed in a short time, significantly improving work efficiency and reducing labor costs. However, the top-down spraying method of drones also presents certain problems, namely, the difficulty in effectively spraying pesticides onto the lower branches and leaves of fruit trees. This may result in pest and disease residues in the lower area of ​​the fruit tree, thus affecting the overall control effect. Utility Model Content

[0005] The purpose of this invention is to provide a spraying device for the prevention and control of fruit tree diseases and pests, which adopts an automatic up-and-down swing spraying method, which can improve spraying efficiency and ensure comprehensive coverage of all parts of the fruit tree.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A spraying device for controlling fruit tree diseases and pests includes a vehicle body, with wheels at the lower end of the vehicle body and a liquid storage tank at the upper end of the vehicle body. A slide rail is vertically arranged in the middle of the rear end of the vehicle body, and a vertical slide bar is slidably connected to the slide rail. A drive disc is rotatably connected to the vehicle body below the vertical slide bar. A drive motor for driving the drive disc to rotate is installed in the vehicle body. A connecting rod is rotatably connected between the eccentric part of the drive disc and the lower end of the vertical slide bar. Vertically arranged rotating frames are provided on both sides of the slide rail. Each rotating frame is rotatably connected to multiple spray sleeves distributed along its height direction and rotating in a vertical plane. Each spray sleeve has an opening at one end away from the slide rail, and the end of each spray sleeve away from the opening is rotatably connected to the side of the vertical slide rail. Each spray sleeve has multiple air inlets at the end away from the opening. Each spray sleeve is equipped with an electric fan. A spray pipe is provided outward from the side of the corresponding electric fan away from the corresponding air inlet in each spray sleeve. A spray nozzle is provided at the end of each spray pipe away from the corresponding electric fan. Each rotating frame is equipped with a high-pressure spray pipe arranged along its height direction. Each high-pressure spray pipe is connected to multiple infusion hoses connected to the corresponding spray pipe. A water pump is installed on the vehicle body. The inlet end of the water pump is connected to the storage tank, and the outlet end of the water pump is connected to an outlet pipe connected to each high-pressure spray pipe.

[0007] By adopting the above technical solution, when spraying pesticides in the orchard, the water pump works, causing the pesticide solution to flow through the high-pressure spray pipe, infusion hose, and spray pipe, finally exiting from the spray nozzle. Simultaneously, the electric fan generates an outward high-pressure airflow, spraying the atomized pesticide solution outward at high speed. The airflow causes the branches and leaves of the fruit trees to sway, ensuring the pesticide solution reaches the inner branches and leaves. Furthermore, the drive motor drives the drive disc to rotate, and the rotating drive disc, through a connecting rod, pulls the vertical slide rails up and down. The up-and-down movement of the slide rails, through the rotating swing arm, causes the spray sleeve to swing up and down, allowing the pesticide mist to oscillate and spray onto the fruit trees, ensuring complete coverage of the branches and leaves and improving the control effect.

[0008] A further feature of this invention is that one end of the drive disc is connected to a transmission pulley, the power output shaft of the drive motor is connected to a drive pulley, and the transmission pulley and the drive pulley are connected by a belt drive.

[0009] A further feature of this invention is that the slide rail is hollow and open at the bottom, the vertical slide bar is slidably connected within the slide rail, the slide rail has grooves on both sides, the vertical slide bar has rotating heads on both sides corresponding to the spray sleeves, and each spray sleeve has a rotating swing arm rotatably connected to the corresponding rotating head at the end away from its opening.

[0010] A further feature of this invention is that the upper end of the liquid storage tank is provided with a liquid filling port, and the liquid filling port is detachably connected with a sealing cap.

[0011] A further feature of this invention is that each rotating frame has multiple rotating holes corresponding to the spray sleeves, and each spray sleeve has a rotating shaft on one side that is rotatably connected to the corresponding rotating hole. Each rotating shaft extends out of the corresponding rotating hole and is provided with a limiting piece.

[0012] In summary, this utility model has the following beneficial effects: This utility model uses an automatic atomized spraying method to replace manual labor, which can effectively improve work efficiency and reduce labor costs. At the same time, during the spraying process, it can swing up and down to form an oscillating mist airflow, which evenly sprays the pesticide onto the branches and leaves of the fruit trees. The mist airflow can also blow and sway the branches and leaves of the fruit trees, so that the inner branches and leaves can be sprayed with the pesticide. The pesticide can more comprehensively cover the branches and leaves of the fruit trees, resulting in better prevention and control effects. Attached Figure Description
