Description

Technical Field

[0001] This invention relates to an orchard spraying system, belonging to the field of orchard spraying technology. Background Technology

[0002] In the agricultural sector, orchard management and maintenance are undoubtedly crucial. Among these aspects, pest and disease control is a key component, directly impacting the health of fruit trees and the quality of the fruit. To effectively address this challenge, orchard spraying equipment has become an indispensable tool for fruit farmers.

[0003] While current orchard sprayers have played a role in controlling pests and diseases, some problems still exist in practical applications. Firstly, traditional orchard sprayers typically rely solely on manual stirring to mix the pesticide solution. Some pesticides have poor solubility, making it difficult to achieve uniform mixing through simple stirring. This can lead to uneven pesticide concentrations during spraying, affecting the control effect. Areas with excessively high concentrations may cause phytotoxicity, harming fruit trees and fruits, while areas with excessively low concentrations may fail to effectively control pests and diseases, thus impacting the overall control outcome.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0005] To address the shortcomings of the prior art, this invention provides an orchard spraying system that can mix pesticides through its built-in pesticide circulation system, ensuring uniform mixing and complete dissolution of the pesticides, thus avoiding pesticide residues and reducing environmental pollution.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] An orchard spraying system includes a main spray tank with a water inlet on the top.

[0008] It also includes an inlet filter, which is connected to the main medicine tank via a three-way valve;

[0009] It also includes a diaphragm pump and a pressure control valve. The premixed drug solution flows from the inlet filter to the diaphragm pump through the pumping action of the diaphragm pump, and then flows to the pressure control valve.

[0010] The pressure control valve is equipped with two liquid nozzles and is connected to the main medicine tank via a pipeline.

[0011] Furthermore, an outlet filter is installed between the pressure control valve and the diaphragm pump, and a reflux switch is installed at the lower end of the outlet filter. The reflux switch of the outlet filter is connected to the main medicine tank through a pipeline.

[0012] Furthermore, the diaphragm pump is equipped with a flushing water circuit switch, and the filter screen is equipped with a flushing nozzle.

[0013] Furthermore, the pressure control valve is equipped with a working state selection knob, and the working states of the pressure control valve include overflow state, stop state, left side injection state, both sides injection state, and right side injection state.

[0014] Furthermore, the main medicine box is equipped with a cleaning water tank, which is connected to the inlet filter via a three-way valve.

[0015] Furthermore, the diaphragm pump is also equipped with a cleaning water circuit switch, and the main medicine tank is equipped with a cleaning nozzle.

[0016] Furthermore, a filter screen is installed at the water inlet.

[0017] Furthermore, a drain outlet is provided at the bottom of the main medicine box.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] 1. Adjust the pressure control valve to overflow mode. In this mode, the premixed solution flows into the inlet filter through the three-way valve, and then flows to the pressure control valve through the pumping action of the diaphragm pump. Finally, it flows back to the main tank from the pressure control valve. In the continuous circulation process, the agent and water are completely mixed. After thorough mixing, the agent is then sprayed, which improves the efficacy.

[0020] 2. The diaphragm pump is equipped with a flushing water circuit switch, and the filter screen is equipped with a flushing nozzle. The medicine flowing out from the flushing water circuit switch flows into the flushing nozzle inside the filter screen to form a flushing circuit. The residual medicine on the medicine packaging bag and the filter screen is flushed through the flushing nozzle, thereby reducing environmental pollution.

[0021] 3. After the first filtration by the inlet filter, the liquid medicine will enter the outlet filter for a second filtration, thereby improving the purity of the liquid medicine reaching the nozzle and ensuring that there are no impurities or particles clogging the nozzle, thus guaranteeing the spraying effect of the liquid medicine.

[0022] 4. The diaphragm pump is also equipped with a cleaning water circuit switch, and the main medicine tank is equipped with a cleaning nozzle. The cleaning water flowing out of the cleaning nozzle flows to the cleaning nozzle in the main medicine tank to form a cleaning circuit. The cleaning nozzle sprays clean water onto the inner wall of the main medicine tank to clean the main medicine tank. At the same time, the cleaning water flows to the rinsing nozzle through the flushing circuit to clean the filter screen.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0029] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] like Figure 1-3 As shown, the present invention provides an orchard spraying system, which includes three working processes: a pesticide addition process, a spraying process, and a cleaning process. After adding pesticide, the system first performs the pesticide addition process to fully mix the pesticide solution, then performs the spraying process to spray the orchard, and finally performs the cleaning process to wash the pesticide solution in the system with clean water.

[0031] The present invention includes a main medicine tank 1, the top of which is provided with a water inlet 2 and a filter screen 3 is installed at the water inlet 2. Water and medicine are added to the main medicine tank 1 through the water inlet 2 according to the required concentration to form a premixed medicine solution. The filter screen 3 installed at the water inlet can perform preliminary filtration on the liquid during the addition process.

[0032] The present invention also includes an inlet filter 6, which is connected to the main medicine tank 1 via a three-way valve 5.

[0033] It also includes a diaphragm pump 7 and a pressure control valve 11. The premixed drug solution flows from the inlet filter 6 to the diaphragm pump 7 through the pumping action of the diaphragm pump 7, and then flows to the pressure control valve 11.

[0034] The pressure control valve 11 is equipped with two liquid nozzles 12, and the pressure control valve 11 is connected to the main medicine tank 1 through a pipeline.

[0035] The pressure control valve 11 is used to adjust the pressure of the liquid medicine sprayed from the liquid medicine nozzle 12. The pressure control valve 11 is also equipped with a working state selection knob. The working states of the pressure control valve 11 include overflow state, stop state, left side spraying state, both sides spraying state and right side spraying state.

[0036] A liquid outlet filter 10 is provided between the pressure control valve 11 and the diaphragm pump 7. A reflux switch is provided at the lower end of the liquid outlet filter 10. The reflux switch of the liquid outlet filter 10 is connected to the main medicine tank 1 through a pipeline.

[0037] Dosing process:

[0038] First, turn on the medicine circulation system to thoroughly mix the medicine. Its circulation loop is as follows: Figure 1 As shown, when the pressure control valve 11 is adjusted to the overflow state, the premixed medicine solution flows into the inlet filter 6 through the three-way valve 5, and then flows to the pressure control valve 11 through the pumping action of the diaphragm pump 7, and finally flows back to the main medicine tank 1 from the pressure control valve 11. In the continuous circulation process, the medicine and water are completely mixed. After being fully mixed, the medicine is then sprayed, which improves the efficacy.

[0039] The liquid outlet filter 10 further filters the liquid medicine. The reflux switch of the liquid outlet filter 10 is in the open state, and part of the liquid medicine flows back to the main medicine tank 1 from the reflux switch for mixing.

[0040] The medicine and water undergo preliminary filtration when added to filter screen 3, then flow through inlet filter 6 for the first filtration, and then flow to outlet filter 10 for the second filtration, in order to ensure the purity of the medicine solution.

[0041] The diaphragm pump 7 is equipped with a flushing water circuit switch 9, and the filter screen 3 is equipped with a flushing nozzle 1401. The medicine flowing out from the flushing water circuit switch 9 flows into the flushing nozzle 1401 in the filter screen 3, forming a flushing circuit 14. The residual medicine on the medicine packaging bag and the filter screen 3 is flushed through the flushing nozzle 1401, thereby reducing environmental pollution.

[0042] Spraying process:

[0043] The pesticide circulation loop during the spraying process is as follows: Figure 2 As shown, the first step is to adjust the three-way valve 5 to a specific position so that the main medicine tank 1 is connected to the inlet filter 6. After adjusting the three-way valve 5, the mixed medicine solution begins to flow out from the pipe below the main medicine tank 1. The mixed medicine solution flows through the three-way valve 5 and the inlet filter 6 in sequence. The inlet filter 6 can perform the first filtration of the medicine solution to ensure its purity.

[0044] After the first filtration by the inlet filter 6, the liquid medicine flows into the diaphragm pump 7, which pressurizes the liquid medicine to ensure that it has a certain pressure before reaching the liquid medicine nozzle 12. This allows the sprayed liquid medicine to better cover the target area. Then, the liquid medicine enters the outlet filter 10 for a second filtration, thereby improving the purity of the liquid medicine reaching the liquid medicine nozzle 12 and ensuring that there are no impurities or particles clogging the liquid medicine nozzle 12, thus guaranteeing the spraying effect of the liquid medicine.

[0045] After filtration, the pesticide solution reaches pressure control valve 11. Depending on the specific needs of the orchard, the pressure of pressure control valve 11 is adjusted. At this time, the working state of pressure control valve 11 is adjusted to left-side spray, side-side spray, or right-side spray. After adjustment by pressure control valve 11, the pesticide solution reaches the left and right pesticide nozzles 12. The pesticide nozzles 12 can atomize the pesticide into fine droplets and spray them evenly onto the target area. During this process, the water circuit switch below the outlet filter 10 can be opened to ensure that the pesticide can flow smoothly back to the main tank 1 in case of water pressure overload, thereby stabilizing the pressure within the system.

[0046] Cleaning process:

[0047] The cleaning process's chemical solution circulation loop is as follows: Figure 2 As shown, the main medicine box 1 is equipped with a cleaning water tank 4, which contains cleaning water.

[0048] First, the three-way valve 5 needs to be adjusted to a specific position to connect the cleaning water tank 4 with the inlet filter 6. At this point, clean water flows out from the pipe below the cleaning water tank 4 and enters the inlet filter 6. The inlet filter 6 ensures that any impurities or particles are filtered out before the clean water enters the diaphragm pump 7, maintaining its purity. After passing through the inlet filter 6, the clean water flows into the diaphragm pump 7. The diaphragm pump 7 is used to pump the clean water, ensuring a continuous and stable delivery of clean water and guaranteeing a smooth cleaning process. After being pressurized by the diaphragm pump 7, the clean water enters the outlet filter 10, which further filters out impurities from the clean water.

[0049] After the liquid is filtered, the clean water reaches the pressure control valve 11. The pressure of the pressure control valve 11 is adjusted, and the valve is opened to adjust the spray on both sides to complete the cleaning of the spray pipe and the liquid nozzle 12.

[0050] The diaphragm pump 7 is also equipped with a cleaning water circuit switch 8. The main medicine tank 1 is equipped with a cleaning nozzle 1501. Cleaning water flowing from the cleaning nozzle 1501 flows to the cleaning nozzle 1501 inside the main medicine tank 1, forming a cleaning circuit 15. Clean water is sprayed onto the inner wall of the main medicine tank 1 through the cleaning nozzle 1501 to clean the main medicine tank 1. Simultaneously, through the flushing circuit 14, cleaning water flows to the flushing nozzle 1401 to clean the filter screen 3. Additionally, by opening the return water switch below the outlet filter 10, when the pressure in the circuit exceeds the set pressure, this return water switch allows clean water to flow back to the main medicine tank 1, thereby ensuring stable operation of the cleaning process.

[0051] A drain outlet 13 is provided at the bottom of the main medicine tank 1, through which the medicine liquid or wastewater in the main medicine tank 1 is discharged.
