Description

Technical Field

[0001] The invention relates to the technical field of sprayers, and in particular to a precise electric sprayer used for drug efficacy testing. Background Art

[0002] In the field of agriculture and plant protection, efficacy testing is an important part of evaluating the effects of pesticides or other agents. When conducting efficacy tests, accurate application of pesticides is the key to ensuring the accuracy of test results. However, existing sprayers have some shortcomings in practical applications.

[0003] Traditional sprayers usually have only one medicine box and cannot load one (different repeated medicine liquid) or multiple differently treated medicine liquids at the same time. This results in the need to frequently replace the medicine liquid during efficacy testing. The operation is cumbersome and not only wastes time, but is also prone to errors, affecting the accuracy of the test results.

[0004] In addition, the spray effect of traditional sprayers is not satisfactory. The design of the nozzle often fails to spray the liquid medicine evenly, resulting in unsatisfactory coverage and adhesion of the liquid medicine, thus affecting the evaluation of the efficacy of the medicine.

[0005] During the application process, it is also very important to monitor the various parameters of the spray in real time. However, existing sprayers often lack effective monitoring methods, and cannot timely understand the spray pressure, time, and flow parameters, making it difficult to adjust according to actual conditions, which will also have an adverse effect on the results of the efficacy test.

[0006] At the same time, impurities in the drug solution may affect the efficacy of the drug, and traditional sprayers have limited ability to filter drug solutions and cannot effectively remove impurities, thus affecting the accuracy of the test.

[0007] In addition, the mobility and ease of operation of traditional sprayers need to be improved. In actual efficacy tests, spraying operations need to be performed at different locations. If the sprayer is inconvenient to move, it will bring great difficulties to the test. Moreover, the complicated operation process will also increase the workload and difficulty of the operator.

The electric spray control button 902 is connected to the first electromagnetic valve 301, the second electromagnetic valve 302, the third electromagnetic valve 303 and the fourth electromagnetic valve 304 circuit.

[0053] Working principle of electric sprayer:

[0054] 1. Loading of drug liquids: Load different drug liquids into four small medicine boxes 12, namely, the first small medicine box 121, the second small medicine box 122, the third small medicine box 123, and the fourth small medicine box 124. The capacity of each small medicine box 12 is 2.5L.

[0055] 2. Liquid medicine delivery: The first electromagnetic valve 301, the second electromagnetic valve 302, the third electromagnetic valve 303 and the fourth electromagnetic valve 304 in the medicine box liquid delivery component 2 are controlled by the electric spray control button 902. When it is necessary to deliver the liquid medicine in a small medicine box 12, open the electromagnetic valve on the corresponding medicine delivery tube, and the liquid medicine enters the spray pumping motor 401 through the medicine delivery tube; the large medicine box 11 is filled with clean water. When each small medicine box (the first small medicine box 121, the second small medicine box 122, the third small medicine box 123 and the fourth small medicine box 124) completes the spraying operation, it can be switched to the large medicine box 11, so that clean water flows into the spray, and the sprayer connecting rod and the nozzle device are fully cleaned. The purpose of this is to prevent different agents or pesticides of different concentrations from being infected and mixed with each other, and to ensure the cleanliness of the spray system. After each spraying of the small medicine box is completed, it is promptly switched to clean water for cleaning in the large medicine box 11, which can effectively avoid drug residue and mixing, provide reliable protection for subsequent efficacy tests, and make the test results more accurate and scientific.

[0056] When the pesticide in the first small medicine box 121 is sprayed, the first electromagnetic valve 301 is closed and switched to clean water in the large medicine box 11 for cleaning, which can effectively avoid residual and mixed pesticides. After cleaning, the second electromagnetic valve 302 is opened to spray the second pesticide, and so on, to complete the spray test of four pesticides.

[0057] 3. Spraying power: The spray pumping motor 401 is started to extract the medicine liquid from the medicine delivery tube and deliver the medicine liquid to the sprayer nozzle assembly 5 through the delivery tube 402.

[0058] 4. Spraying operation: The liquid medicine enters the spray connecting pipe 501, passes through the connecting pipe sleeve 502 and enters the spray pipe 503. At the connection between the spray pipe 503 and the connecting pipe, the leakproof sealing ring 7 prevents the liquid medicine from leaking. The liquid medicine is finally sprayed out from the fan-shaped nozzle 504 in the form of spray.

[0059] 5. Monitoring function:

[0060] Pressure monitoring: A pressure gauge 601 is provided on the delivery pipe 402 to monitor the pressure of the drug solution delivery.

[0061] Time recording: The timer 602 is also arranged on the delivery pipe 402 to record the time of spraying.

[0062] Pressure regulation: When the pressure is too high, the pressure relief valve 603 works to release the excess pressure to protect the spray pumping motor 401 and the entire spray system.

[0063] Flow control: The flow control valve can adjust the flow of the liquid medicine to meet different spray requirements.

[0064] Liquid level monitoring: The liquid level sensor 605 on each small medicine box 12 monitors the liquid level of the medicine in the small medicine box 12 in real time, so that the user can understand the remaining amount of the medicine.

[0065] Drug liquid filtration: The drug liquid filter cores 8 on the first drug delivery tube 201 , the second drug delivery tube 202 , the third drug delivery tube 203 and the fourth drug delivery tube 204 filter the drug liquid to remove impurities and ensure the quality of the spray.

[0066] 6. Control and display: The electric spray control display 901 in the electric spray control assembly 9 can display the working status and related parameters of the sprayer, such as the liquid level, spray time, and pressure. The user controls the electromagnetic valve through the electric spray control button 902 to achieve the selection of different liquids in the small medicine box 12 and the control of the spray operation.

[0067] In summary, this precision electric sprayer achieves precise control and spraying operation of different liquid medicines through the coordinated work of various components. It also has a monitoring function and can meet the needs of drug efficacy testing.

[0068] Specific working process of electric sprayer:

[0069] 1. Preparation of Drug Solution

[0070] Pour different medicine liquids into four small medicine boxes 12, namely the first small medicine box 121, the second small medicine box 122, the third small medicine box 123, and the fourth small medicine box 124. The capacity of each small medicine box 12 is 2.5L.

[0071] 2. Start the sprayer

[0072] Turn on the power of the electric spray control assembly 9, and the electric spray control display 901 displays the initial state information of the sprayer.

[0073] 3. Choose the solution

[0074] The electromagnetic valve corresponding to the small medicine box 12 to be sprayed is selected through the electric spray control button 902. For example, if the liquid medicine in the first small medicine box 121 is to be used, the first electromagnetic valve 301 is opened, and the other electromagnetic valves remain closed.

[0075] 4. Liquid drug delivery

[0076] After the corresponding electromagnetic valve is opened, the drug liquid enters the medicine box liquid delivery component 2 through the drug delivery tube connected thereto, such as the first drug delivery tube 201.

[0077] 5. Spray power start

[0078] The liquid medicine in the medicine box liquid delivery assembly 2 enters the spray pumping motor 401 , and the spray pumping motor 401 is started to extract the liquid medicine and deliver it to the sprayer nozzle assembly 5 through the delivery pipe 402 .

[0079] 6. Spray operation

[0080] The liquid medicine enters the spray connection pipe 501, passes through the connection pipe sleeve 502, and enters the spray pipe 503. At the connection between the spray pipe 503 and the connection pipe, the leakproof sealing ring 7 prevents the liquid medicine from leaking. Finally, the liquid medicine is sprayed out from the fan-shaped nozzle 504 in the form of spray.

[0081] 7. Monitoring process

[0082] During the spraying process, the pressure gauge 601 monitors the pressure of the liquid medicine in the delivery pipe 402 in real time, and the timer 602 records the spraying time.

[0083] The liquid level sensor 605 monitors the liquid level of each small medicine box 12 in real time and displays the information on the electric spray control display 901.

[0084] The flow meter 604 monitors the flow rate of the liquid medicine in the spray tube 503 .

[0085] When the pressure in the delivery pipe 402 is too high, the pressure relief valve 603 automatically opens to release the excess pressure and protect the spray system.

[0086] 8. Switching the solution

[0087] The large medicine box 11 is filled with clean water. After each small medicine box (the first small medicine box 121, the second small medicine box 122, the third small medicine box 123 and the fourth small medicine box 124) completes the spraying operation, it can be switched to the large medicine box 11 to allow clean water to flow into the spray, and the sprayer connecting rod and the nozzle device are fully cleaned. The purpose of this is to prevent different agents or pesticides of different concentrations from being infected and mixed with each other, and to ensure the cleanliness of the spray system. After each small medicine box is sprayed, it is promptly switched to the clean water of the large medicine box 11 for cleaning, which can effectively avoid agent residue and mixing, provide reliable protection for subsequent efficacy tests, and make the test results more accurate and scientific.

[0088] When the pesticide in the first small medicine box 121 is sprayed, the first electromagnetic valve 301 is closed and switched to clean water in the large medicine box 11 for cleaning, which can effectively avoid residual and mixed pesticides. After cleaning, the second electromagnetic valve 302 is opened to spray the second pesticide, and so on, to complete the spray test of four pesticides.

[0089] 9. After the spraying is finished and the efficacy test is completed, the spray pumping motor 401 and all electromagnetic valves are turned off to stop the spraying operation.

[0090] Embodiment 2: A precise electric sprayer used for drug efficacy test, four pesticides to be tested are respectively loaded into a first small medicine box 121, a second small medicine box 122, a third small medicine box 123 and a fourth small medicine box 124, each small medicine box 12 has a capacity of 2.5L.

[0091] Through the electric spray control display 901 and the electric spray control button 902, check whether the various solenoid valves, spray pumping motor 401, pressure gauge 601, timer 602, pressure release valve 603, flow control valve and liquid level sensor 605 components are working normally.

[0092] 2. Spray operation

[0093] Set the test parameters, such as spray pressure, spray time and liquid flow rate.

[0094] First, open the first electromagnetic valve 301, start the spray pumping motor 401, and deliver the pesticide in the first small medicine box 121 to the sprayer nozzle assembly 5 through the delivery pipe 402, and evenly spray it on the test plant through the fan-shaped nozzle 504. At the same time, the pressure gauge 601, the timer 602 and the flow meter 604 monitor the spray pressure, time and flow in real time. The large medicine box 11 is filled with clean water. When each small medicine box (the first small medicine box 121, the second small medicine box 122, the third small medicine box 123 and the fourth small medicine box 124) completes the spraying operation, it can be switched to the large medicine box 11, so that clean water flows into the spray, and the sprayer connecting rod and the nozzle device are fully cleaned. The purpose of doing this is to prevent different agents or pesticides of different concentrations from being infected and mixed with each other, and to ensure the cleanliness of the spray system. After each small medicine box spray is completed, it is promptly switched to the clean water of the large medicine box 11 for cleaning, which can effectively avoid the residue and mixing of the agent, provide reliable protection for the subsequent efficacy test, and make the test results more accurate and scientific.

[0095] When the pesticide in the first small medicine box 121 is sprayed, the first electromagnetic valve 301 is closed and switched to clean water in the large medicine box 11 for cleaning, which can effectively avoid residual and mixed pesticides. After cleaning, the second electromagnetic valve 302 is opened to spray the second pesticide, and so on, to complete the spray test of four pesticides.

[0096] 3. Test records

[0097] During the spraying process, the spraying time, spraying pressure, liquid flow rate and liquid level change data of each pesticide are recorded in detail.

[0098] Observe the reactions of the test plants and record the efficacy of the pesticides, such as the effects on pest control and disease prevention and the growth conditions of the plants.

[0099] 4. End of the experiment

[0100] After the spray test is finished, the spray pumping motor 401 and all electromagnetic valves are turned off to clean the residual liquid inside the sprayer.

[0101] The test data are collated and analyzed to obtain the pesticide efficacy evaluation results.

[0102] Example 3: A precision electric sprayer for efficacy testing, plant growth regulator efficacy testing

[0103] 1. Preparation of Drug Solution

[0108] First, open the first electromagnetic valve 301, and let the plant growth regulator in the first small medicine box 121 enter the spray pumping motor 401 through the medicine delivery tube, and then the spray pumping motor 401 will deliver the liquid medicine to the sprayer nozzle assembly 5, and finally spray it from the fan-shaped nozzle 504 and spray it evenly on the test plants. During this process, the monitoring component 6 will monitor the various parameters of the spray in real time. The large medicine box 11 is filled with clean water. When each small medicine box (the first small medicine box 121, the second small medicine box 122, the third small medicine box 123 and the fourth small medicine box 124) completes the spraying operation, it can be switched to the large medicine box 11 to allow clean water to flow into the spray, and the sprayer connecting rod and the nozzle device are fully cleaned. The purpose of this is to prevent different agents or pesticides of different concentrations from being infected and mixed with each other, and to ensure the cleanliness of the spray system. After each spraying of the small medicine box is completed, it is promptly switched to clean water for cleaning in the large medicine box 11, which can effectively avoid drug residue and mixing, provide reliable protection for subsequent efficacy tests, and make the test results more accurate and scientific.

[0109] The plant growth regulators in the four small medicine boxes 12 are sprayed in turn according to a predetermined sequence.

[0110] 3. Data recording and observation

[0111] The time, pressure, flow rate data of each spraying, and the usage amount of the liquid medicine in each small medicine box 12 are recorded.

[0112] Regularly observe the growth of test plants, such as plant height, leaf area, and root development, and record the effects of plant growth regulators on plant growth.

[0113] 4. End of the experiment

[0114] After completing all spraying operations, turn off the power supply and all valves of the sprayer.

[0115] Clean the sprayer and dispose of any remaining liquid medicine properly.

[0116] The test data were analyzed to evaluate the regulatory effects of different concentrations of plant growth regulators on plant growth; the purpose of the experiment was to test the control effect of the precision electric sprayer on plant diseases and insect pests under different liquid combinations and spray parameters.

[0123] 2. Open the first electromagnetic valve 301, start the spray pumping motor 401, and spray the first pesticide solution on the first test field. During the spraying process, the monitoring component 6 monitors the spray pressure, time, and flow parameters in real time to ensure the accuracy of the spraying operation.

[0124] 3. After the spraying of the first pesticide liquid is completed, the first electromagnetic valve 301 is closed, the second electromagnetic valve 302 is opened, and the second pesticide liquid is sprayed on the first test field according to the same spray parameters.

[0125] 4. Similarly, the first test field was sprayed with four types of pesticide solutions in sequence.

[0126] 5. Push the precision electric sprayer to the second test field, adjust the spray parameters to spray pressure of 4MPa, spray time of 6 minutes, and liquid flow rate of 2.5L / min, and then carry out spray treatment according to the same liquid sequence and operation method as the first test field.

[0127] 6. Push the precision electric sprayer to the third test field, set the spray parameters as spray pressure of 5MPa, spray time of 7 minutes, and liquid flow rate of 3L / min, and also carry out spray treatment according to the order of liquid.

[0128] 7. On the 1st, 3rd, 5th and 7th day after spraying, observe and record the plant disease and insect pest conditions in the three test fields, including the types, quantities and degree of damage of the diseases and insect pests.

[0129] 8. Evaluate and analyze the pest control effects of the three experimental fields, and compare the pest control effects of different spray parameters and liquid combinations.

[0130] Experimental results and analysis:

[0131] Through the observation and data recording of three test fields, the control effects of different spray parameters and liquid medicine combinations on plant diseases and insect pests are analyzed. For example, if the spray pressure in the first test field is 3MPa, the spray time is 5 minutes, and the liquid medicine flow rate is 2L / min, the number of pests and diseases is significantly reduced, and the degree of harm is reduced, indicating that the spray parameters and liquid medicine combination have a good control effect on pests and diseases. By comparing the results of the three test fields, the best spray parameters and liquid medicine combination can be obtained, which provides a reference for actual pest control.
