Description

Technical Field

[0001] This utility model relates to the field of pest and weed control technology, specifically to a pesticide application device for pest and weed control. Background Technology

[0002] In the prevention and control of pests and weeds in agricultural greenhouses, the spraying device needs to balance efficient spraying with operational safety. Taking a spraying device for pest and weed control disclosed in patent CN222264141U as an example, this spraying device can be used to spray crops in the greenhouse to prevent and control pests and weeds. It can build a track in the greenhouse so that the spraying equipment, consisting of a base, medicine tank, water pump, liquid supply pipe, and nozzle, can move along the track. The nozzle can spray while moving. The spraying equipment can move on the track without the need for workers to push it, so that workers do not need to enter the spraying environment, which can avoid workers inhaling the medicine and improve the spraying efficiency. However, atomized pesticides settle quickly in static air, making it difficult to penetrate the crop canopy, resulting in insufficient coverage on the underside of leaves and lower branches. At the same time, traditional nozzles rely solely on liquid pressure for atomization, resulting in uneven droplet size distribution, which easily leads to localized accumulation or loss on the leaf surface, reducing the control effect and increasing pesticide waste. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pesticide application device for the control of diseases, pests and weeds, which can effectively solve the problem that it is difficult to spray the atomized pesticide solution onto the back of the leaf in the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a pesticide application device for the control of diseases, pests, and weeds, comprising: Slide rail; Atomizing spray assembly includes a liquid storage tank disposed below a slide rail, a guide pipe fixedly installed at the lower end of the liquid storage tank, an atomizing nozzle disposed inside the guide pipe, and external hollow frames symmetrically disposed on both sides of the liquid storage tank, the lower end of the external hollow frames being fixedly connected to the outer wall of the guide pipe. An air supply assembly, the air supply assembly including an air delivery chamber opened in an external hollow frame, the air delivery chamber being connected to a guide pipe.

[0005] Preferably, a movable frame is slidably installed on the outer wall of the slide rail, the lower end of the movable frame is fixedly connected to the liquid storage tank, and a flared mouth is fixedly installed on the lower end face of the guide pipe.

[0006] Preferably, a water pump is fixedly installed at the lower end of the liquid storage tank and inside the guide pipe, and an atomizing nozzle is fixedly installed at the output end of the water pump.

[0007] Preferably, the lower end face of the external hollow frame is connected to a connecting pipe, the lower end face of the connecting pipe is connected to an annular jet pipe, the lower end face of the annular jet pipe is provided with a jet port, a regulating valve is fixedly installed on the inner wall of the air supply chamber near the guide pipe, and a solenoid valve is fixedly installed on the inner wall of the connecting pipe.

[0008] Preferably, an external block is fixedly installed on one side of the mobile frame, an air inlet is fixedly installed on one end of the external block, a bracket is fixedly installed inside the air inlet, a rotary drive is fixedly installed on the upper end of the bracket, and a fan blade is fixedly installed on the output end of the rotary drive through the bracket. The fan blade is rotatably connected to the bracket.

[0009] Preferably, the lower end of the air inlet barrel is connected to an air inlet pipe, and the lower end of the air inlet pipe is connected to the air delivery chamber.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. The fan blades are driven by a rotating drive to generate a high-speed airflow. After being split by the air delivery chamber, most of the airflow blows downwards onto the plant through the nozzle of the annular jet pipe. This airflow forcibly disturbs the leaves, fully exposing both the front and back of the leaves. At the same time, a small portion of the airflow is injected into the guide pipe through the regulating valve and mixes with the pesticide mist sprayed from the atomizing nozzle to form a two-phase flow of gas and liquid. The synergistic effect of the two airflows (i.e., leaf disturbance + droplet delivery) allows the pesticide to penetrate to the lower branches and leaves and the dead corners on the back of the leaves, solving the problem of blind spots caused by leaf shading in static pesticide application. 2. By adding a flared end to the guide tube, combined with the airflow into the air delivery chamber, the atomizing nozzle sprays a secondary diffusion and acceleration of the drug mist. The airflow forces the drug mist to form a swirling flow in the flared end, which greatly refines the droplet size and improves the uniformity of distribution. At the same time, the airflow pushes the droplets to the leaf surface quickly, shortening their suspension time in the air and reducing the loss of drug solution caused by natural settling or drift.

A guide pipe 206 is fixedly installed at the lower end of the liquid storage tank 202. An atomizing nozzle 205 is installed inside the guide pipe 206. External hollow frames 203 are symmetrically arranged on both sides of the liquid storage tank 202. The lower end of the external hollow frame 203 is fixedly connected to the outer wall of the guide pipe 206. A water pump 204 draws the liquid from the liquid storage tank 202 to the guide pipe 206, where it is broken into droplets of 80~150μm by the atomizing nozzle 205 (the nozzle can be replaced to adjust the particle size according to the type of crop). For example, coarse droplets (above 120μm) are used for leafy vegetables, while fine droplets (below 100μm) are needed for aphid control. The air supply assembly 3 includes an air delivery chamber 301 opened inside the external hollow frame 203, and the air delivery chamber 301 is connected to the guide pipe 206.

[0017] Reference Fig. 2 A movable frame 201 is slidably installed on the outer wall of the slide rail 1. The lower end of the movable frame 201 is fixedly connected to the liquid storage tank 202. A flared mouth 207 is fixedly installed on the lower end face of the guide pipe 206. The movable frame 201 moves automatically along the slide rail 1 (the walking speed is adjustable from 0.3 to 1.2 m / s), driving the liquid storage tank 202 to be positioned in the crop area. After setting the path through a handheld terminal, the worker does not need to enter the application area.

[0018] Reference Fig. 2 A water pump 204 is fixedly installed at the lower end of the liquid storage tank 202 and inside the guide pipe 206, and an atomizing nozzle 205 is fixedly installed at the output end of the water pump 204.

[0019] Reference Figs. 2-3 The lower end face of the external hollow frame 203 is connected to a connecting pipe 303, and the lower end face of the connecting pipe 303 is connected to an annular jet pipe 304. The lower end face of the annular jet pipe 304 has a jet port. A regulating valve 302 is fixedly installed on the inner wall of the air supply chamber 301 near the guide pipe 206. A solenoid valve is fixedly installed on the inner wall of the connecting pipe 303. The solenoid valve is a normally open solenoid valve.

[0020] Reference Figs. 2-3 An external block 305 is fixedly installed on one side of the mobile frame 201. An air inlet 306 is fixedly installed on one end of the external block 305. A bracket 307 is fixedly installed inside the air inlet 306. A rotary drive 308 is fixedly installed on the upper end of the bracket 307. The rotary drive 308 uses an existing motor. The output end of the rotary drive 308 passes through the bracket 307 and is fixedly installed with a fan blade 309. The fan blade 309 is rotatably connected to the bracket 307.

[0021] Reference Figs. 2-3 The lower end of the air intake barrel 306 is connected to the air intake pipe 310, and the lower end of the air intake pipe 310 is connected to the air delivery chamber 301. The rotating drive component 308 drives the fan blades 309 to generate an airflow of 8-10 m / s, which is input into the air delivery chamber 301 through the air inlet pipe 310. 70%-80% of the airflow enters the annular jet pipe 304 through the connecting pipe 303 and blows downwards onto the crop (causing the leaves to turn over and expose the back). 20%-30% of the airflow is injected into the guide pipe 206 through the regulating valve 302 and mixes with the droplets to form a gas-liquid two-phase flow (to prevent the droplets from accumulating on the pipe wall).

[0022] The working principle of this utility model is as follows: The slide rail 1 is installed inside the greenhouse to facilitate the movement of the atomizing spray assembly 2 and the air supply assembly 3 within the greenhouse. The pesticide is mixed with water and placed inside the storage tank 202. As the slide rail 1 drives the moving frame 201 to move the storage tank 202, the water pump 204 is activated to extract the pesticide solution from the storage tank 202 and spray it through the atomizing nozzle 205, atomizing the pesticide solution within the guide pipe 206. The rotating drive component 308 drives the fan blades 309 to rotate within the air intake 306, drawing outside air into the air intake 306, which is then discharged into the air delivery chamber 301 through the air intake pipe 310. First, the solenoid valve is opened, allowing most of the air to be delivered from the air delivery chamber 301 to the connecting pipe 303. Then, the air is blown out onto the plant through the annular jet pipe 304, causing the plant leaves to sway. After most of the air has been delivered through the solenoid valve box connecting pipe 303 and the annular jet pipe 304, the regulating valve 302 is opened, allowing some air to be delivered through the air delivery chamber 301 to the guide pipe 206, which in turn delivers the atomized pesticide to the surface of the plant. In this way, most of the air blows and sways the plant leaves, allowing the atomized pesticide to be sprayed evenly on both sides of the plant leaves, avoiding uneven spraying that could damage the plant due to pests or other pests.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
