Description

Technical Field

[0001] This utility model relates to an agricultural pesticide application device, specifically a combined spraying device. Background Technology

[0002] Cucurbit crops exhibit vigorous branching; for example, the common watermelon can have as many as 8-9 primary branches. During the flowering and fruiting period, it has numerous leaves with a large surface area, and the creeping branches and leaves intertwine and shade each other. During the growing season, common watermelons are severely affected by pests and diseases. Existing spraying machinery and methods apply pesticides from above the leaves. While the uppermost leaves can fully receive the pesticide, the pesticide cannot penetrate the leaf layer from top to bottom. This results in uneven pesticide distribution on the undersides of the leaves and in areas where leaves overlap, failing to achieve uniform pesticide application across the entire field.

[0003] The underside of melon leaves has more stomata than the upper side. These stomata are the respiratory channels through which plants exchange gases with the environment, making them susceptible to pathogen infection. Furthermore, the underside of leaves is less affected by sunlight, wind, and rain, making it even more vulnerable to pathogens. Existing spraying machinery and methods cannot completely eliminate pathogens and insect eggs in the field, and pest and disease control is short-lived, requiring more frequent applications of pesticides, manpower, and resources for pest and disease control. Therefore, there is a need to design a device suitable for applying pesticides to cucurbit crops. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a combined spraying device to address the shortcomings of the prior art. The device has a scientific and reasonable structural design, is highly practical, and firstly separates the leaves by disturbing the airflow close to the ground, and then increases the coverage of the pesticide on the crop leaves by spraying the pesticide from top to bottom and from the left and right sides, thereby improving the application efficiency, ensuring the effect of preventing pests and diseases on crops, and having a low manufacturing cost, which can be widely used.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a combined spraying device, characterized in that it includes a combined pipe, independent pipes, and combined nozzles. The combined pipe and independent pipes are mounted on a support, and the distance between the independent pipes and the combined pipe is 1-1.5m. The combined pipe is set above the rows of planted crops. Multiple combined nozzles are equidistantly connected to the lower side of the combined pipe, and multiple liquid spray nozzles are equidistantly connected to the lower side of the independent pipes. The combined pipe includes an air supply pipe and a liquid supply pipe fixedly installed side by side. The air supply pipe is connected to a pressurized air tank, and the liquid supply pipe and independent pipe are connected to a pressurized pesticide tank. The pressurized air tank and pressurized pesticide tank are set at the front end of the sprayer. The combined nozzle is provided with a pesticide pipe connector, a spray head, an air pipe connector, and a jet nozzle. The inlet end of the pesticide pipe connector is connected to the liquid supply pipe, and two spray heads are connected to both sides of the outlet end of the pesticide pipe connector. The inlet end of the air pipe connector is connected to the air supply pipe, and two jet nozzles are connected to both ends of the outlet end of the air pipe connector. The pesticide pipe connector and the air pipe connector are fixedly connected.

[0006] Preferably, the infusion tube is connected to the medicine tube connector via a drooping tube, the gas infusion tube is connected to the gas tube connector via a drooping tube, and the independent tube is connected to the medicine direct spray head via a drooping tube.

[0007] Preferably, the combined nozzle is 10cm above the ground, a liquid valve is installed at the position where the infusion pipe connects to the pressurized pesticide tank, a liquid valve is installed at the position where the independent pipe connects to the pressurized pesticide tank, and a gas valve is installed at the position where the gas infusion pipe connects to the pressurized gas tank.

[0008] This utility model has the following advantages compared with the prior art:

[0009] 1. This utility model utilizes a combined spraying method, employing a top-down spraying approach within crop planting rows to ensure even distribution of pesticide solution across stems, leaves, and unshaded lower stems and leaves, as well as in the surrounding space. Between leaf planting rows, airflow disturbance and side-to-side spraying are used. Airflow disturbance causes temporary separation between leaves touching the ground and leaves overlapping each other, while side-to-side spraying ensures even distribution of pesticide solution across the lower parts of shaded leaves and the ground, thereby improving operational efficiency and achieving optimal control effects.

[0010] 2. This utility model has a simple and reasonable structure, low manufacturing cost, strong practicality, easy installation, and good application effect and high efficiency.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0015] Detailed Implementation

[0016] like Figure 1 and Figure 2As shown, this utility model includes a combined pipe, independent pipes 8, and combined nozzles 7. The combined pipe and independent pipes are mounted on a bracket, with a spacing of 1-1.5m between them. The combined pipe is positioned above the rows of planted crops. Multiple combined nozzles 7 are equidistantly connected to the lower side of the combined pipe, and multiple liquid spray nozzles 9 are equidistantly connected to the lower side of the independent pipes 8. The combined pipe includes a gas supply pipe 5 and a liquid supply pipe 6 fixedly installed side by side. The gas supply pipe 5 is connected to a pressurized gas tank, and the liquid supply pipe 6... A pressurized pesticide tank is connected to an independent pipe 8. The pressurized air tank and the pressurized pesticide tank are located at the front end of the sprayer. The combined nozzle 7 is equipped with a pesticide hose connector 1, a spray head 2, an air hose connector 3, and a jet nozzle 4. The inlet end of the pesticide hose connector 1 is connected to an infusion pipe 6, and the two outlet ends of the pesticide hose connector 1 are connected to two spray heads 2. The inlet end of the air hose connector 3 is connected to an air supply pipe 5, and the two outlet ends of the air hose connector 3 are connected to two jet nozzles 4. The side walls of the pesticide hose connector 1 and the air hose connector 3 are welded and fixed. The jet direction of the two jet nozzles 4 is inclined upward at 45°, and the spray direction of the two spray heads 2 is horizontal.

[0017] In this embodiment, the infusion tube 6 is connected to the medicine tube connector 1 via the drooping tube 10, the gas infusion tube 5 is connected to the gas tube connector 3 via the drooping tube 10, and the independent tube 8 is connected to the medicine direct spray head 9 via the drooping tube 10.

[0018] In this embodiment, the combined nozzle 7 is 10cm above the ground, the direct spray nozzle 9 is above the crop, the infusion pipe 6 is connected to the pressurized pesticide tank with a liquid valve, the independent pipe 8 is connected to the pressurized pesticide tank with a liquid valve, and the gas pipe 5 is connected to the pressurized gas tank with a gas valve. The independent pipe 8, the gas pipe 5, and the infusion pipe 6 are controlled by independent valves.

[0019] When using, first turn on the 10cm ground-level spray head 4 to spray airflow to both sides, briefly separating the ground-level leaves from the shaded leaves. Then spray pesticide from the spray head 2 to both sides, creating droplet mist around the lower branches and leaves of the plant, allowing the pesticide to fully contact the ground and leaves, thoroughly killing pests and diseases at the lower part of the plant. Next, turn on the independent pipe 8 and spray pesticide from top to bottom from the direct spray head 9, ensuring that the upper leaves and exposed ground fully receive the pesticide, increasing the coverage area of ​​the pesticide.

[0020] In practice, the focus is on disease control for watermelons. The main disease outbreak period is 60 days from July to August each year. Currently, large-scale growers in watermelon producing areas control diseases by spraying pesticides 10-12 times, averaging once every 5 days. Generally, pesticides are effective for 10-15 days, and only 4-5 sprays are needed to achieve the desired control during the 60-day disease outbreak period.

[0021] This invention enables uniform spraying across the entire field, eliminating previously unsprayable areas such as the undersides of leaves, overlapping leaves, and the ground, thus completely eradicating pathogens. This invention will significantly reduce the number of pesticide applications and the amount of pesticides and labor required, achieving the goals of cost reduction and efficiency improvement.

[0022] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any simple modifications, alterations, and equivalent changes made to the above embodiments based on the technical essence of this utility model shall still fall within the protection scope of this utility model.
