Description

Technical Field

[0001] The present invention relates to the technical field of pesticide preparation mixing, and in particular to a method for quickly detecting the effect of pesticide preparation tank mixing. Background Art

[0002] In most pesticide application scenarios, multiple pesticide formulations are mixed and used, which often causes flocculation and stratification, leading to pesticide denaturation, nozzle clogging and reduced efficacy. The fundamental reason for the flocculation and stratification of pesticide tank mixes lies in the combined effect of the conflicting physical and chemical properties of different formulations and improper environmental operations. The ion antagonism of the formula ingredients is one of the core inducements. For example, cations such as calcium and magnesium in the formulation combine with phosphate adjuvants to form precipitates; the difference in solvent polarity destroys the emulsification balance, leading to oil precipitation or particle aggregation. The interaction failure of adjuvants further aggravates the problem. For example, the mismatch of HLB values ​​of different surfactants leads to a decrease in dispersion ability, which directly affects the field application effect. Especially under large-scale planting conditions, farmers often prepare hundreds of liters of liquid medicine at a time. Once flocculation and precipitation occur, huge economic losses will occur.

[0003] In Chinese Patent 202211123145.1, the chemical compatibility of the pesticide solution cannot be detected, and the traditional manual visual inspection method cannot quantify the mixing uniformity. In addition, due to the changing application scenarios and the different formulations of different manufacturers, it is impossible to guide on-site dispensing. Therefore, the present invention proposes a rapid detection method for the tank mixing effect of pesticide formulations to solve the problems existing in the prior art. Summary of the Invention

[0004] In response to the above problems, the purpose of the present invention is to propose a rapid detection method for the tank-mixing effect of pesticide preparations. The rapid detection method for the tank-mixing effect of pesticide preparations can complete the mixing effect evaluation of pesticide preparations in a short time by quickly detecting the physical and chemical parameters of the sample, thereby improving work efficiency. The use of the mixing effect to determine the threshold makes the detection method simple to operate and does not require complex equipment. Compared with traditional laboratory detection methods, the rapid detection method is usually lower in cost, saving detection costs.

[0005] To achieve the purpose of the present invention, the present invention is implemented by the following technical solutions: a rapid detection method for the effect of pesticide formulation tank mixing, comprising the following steps;

[0006] Step 1: Collect representative samples through sampling tubes, ensuring that the sampling points cover different parts of the liquid medicine; collect the prepared mixed liquid medicine.

[0007] Step 2: After the collection is completed, the pesticide sample is quantitatively transferred to the detection container and tested by three sensors installed inside the detection container, namely spectral image detection, turbidity detection and suspended particle detection;

[0008] Step 3: Compare the sensor detection data values ​​at different locations horizontally;

[0009] Step 4: Evaluate the test parameters based on the comparison results, and test the barrel mixes whose parameters are within the preset threshold range. At the same time, if the parameters exceed the preset threshold range, the barrel mix effect will be judged as poor.

[0010] Step 5: Record the sampling location and time, list the sample's spectral image, turbidity, and suspended particle detection values, display the comparison results between the detection values ​​and the preset thresholds, and based on the analysis results, give an overall assessment of the drug solution mixing effect to complete the detection work.

[0011] A further improvement is that in step 1, samples are collected from different parts of the medicinal liquid, the collected samples are introduced into a detection container, and samples are collected from the upper layer, middle layer and lower layer of the medicinal liquid respectively.

[0012] A further improvement is that in step 2, after collecting the samples, the pesticide samples are introduced into the detection container for rapid detection, and the detection equipment is provided with three layers, with three sets of sensors installed above each layer of detection equipment from top to bottom.

[0013] A further improvement is that in step 2, the first layer of the detection container is provided with a group of spectral image sensors, and the second and third layers are respectively provided with three groups of turbidity sensors and three groups of suspended matter sensors. The spectral image sensor of the first layer is a rotary sensor, which obtains spectral images of pesticides through 360° rotation. Six sensors are respectively provided inside the second and third layers, and the angle of each sensor is 60°.

[0014] A further improvement is that in step 2, when performing turbidity and suspended matter detection, the second layer and the third layer are tested simultaneously and the data after the detection are compared to calculate the CV value of the test result.

[0015] A further improvement is that in step three, after completing sample collection and parameter measurement, all measured parameter values ​​including spectral images, turbidity and suspended particle data are recorded.

[0016] A further improvement is that in step four, when making result judgments, it is ensured that the components in the liquid medicine are evenly distributed. When the detection parameter values ​​are all within the preset threshold range, the mixed liquid medicine system is judged to be stable and uniform and can be directly used for field spraying. When the detection parameter values ​​exceed the preset threshold range, it is judged that the effect is poor.

[0017] A further improvement is that in step five, a report template is created to record the comparison analysis and conclusions of the parameters, where the basic parameters of the spectral image are 400nm-700nm, the basic parameter of turbidity is 15NTU, and the basic parameter of suspended particles is 100,000 particles per milliliter, giving an overall evaluation of the mixing effect of the pesticide solution.

[0018] The beneficial effects of the present invention are as follows: the present invention can complete the evaluation of the mixing effect of the pesticide preparation in a short time by quickly detecting the physical parameters and chemical parameters of the sample, thereby improving work efficiency; the use of the mixing barrel effect to determine the threshold value makes the detection method simple to operate; and by setting up multiple groups of different sensors inside the detection container, the pesticide solution is subjected to multi-layer detection; compared with traditional laboratory detection methods, the rapid detection method is usually less expensive, saving detection costs; the rapid detection can provide instant feedback, facilitating timely adjustment of the mixing ratio, and ensuring the quality of the pesticide preparation; through rapid detection, pesticide waste caused by improper mixing can be avoided, which helps to save resources; the rapid detection method reduces the impact on the environment; the preparation and uploading of the detection report to the cloud platform facilitates long-term storage and remote access of data, which helps subsequent data analysis and quality control.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0021] Figure 2 It is a cross-sectional view of the detection container of the present invention. DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] In document 202211123145.1, a 0.04wt% to 0.1wt% solution is diluted with water, and then the pesticide formulation is diluted with this solution for subsequent spraying. This can effectively improve the physical and chemical properties of the pesticide solution, increase the efficiency of the active ingredients reaching the site of action, and thus improve the effect of the pesticide formulation on the target. When the same dose of pesticide formulation is applied, the mortality rate of pests can be increased. The inability to detect the effect of the mixed pesticide formulation will lead to subsequent use. External factors such as high water hardness, sudden temperature changes, and incorrect mixing sequence will destroy the formulation structure. For example, the rupture of the microcapsule wall material will cause the sudden release of active ingredients, or the suspended particles will settle due to the "salting out effect". These physical and chemical imbalances will eventually lead to the loss of uniformity of the solution and the decrease in the stability of the active ingredients, which directly affects the effect of field application. This application uses the confusion effect to quickly detect pesticides. Multiple sets of sensors are used to monitor the spectral images, turbidity, and suspended particle data of pesticides to determine the threshold to ensure the quality of the pesticide formulation mixing, greatly improving the efficiency and quality of detection.

[0025] according to Figure 1 As shown, this embodiment provides a rapid detection method for the tank mix effect of pesticide formulations, comprising the following steps:

[0026] Step 1: Collect representative samples through sampling tubes, ensuring that the sampling points cover different parts of the liquid; collect the prepared mixed liquid;

[0027] Step 2: After the collection is completed, the pesticide sample is quantitatively transferred to the detection container and tested by three sensors installed inside the detection container, namely spectral image detection, turbidity detection and suspended particle detection;

[0028] Step 3: Compare the detected actual parameter value with the preset threshold;

[0029] Step 4: Evaluate the test parameters based on the comparison results. Test the barrel mixes whose parameters are within the preset threshold range. If the parameters exceed the preset threshold range, the barrel mix is ​​judged to be poor and re-mixed and the formula is adjusted.

[0030] Step 5: Record the sampling location and time, list the sample's spectral image, turbidity, and suspended particle detection values, display the comparison results between the detection values ​​and the preset thresholds, and based on the analysis results, give an overall assessment of the drug solution mixing effect to complete the detection work.

[0031] In step one, prepare contamination-free sampling tubes and collect samples from different parts of the liquid medicine. Before sampling, ensure that there is no debris and contaminants on the surface of the liquid medicine around the sampling point. Collect samples from the upper, middle and lower layers of the liquid medicine.

[0032] In step 2, after the samples are collected, the pesticide samples are introduced into the detection container for rapid testing. The detection equipment is set up in three layers, and three sets of sensors are installed above each layer of detection equipment from top to bottom. After the sample is added to the detection container, they are respectively a spectral image sensor, a turbidity sensor and a suspended matter concentration sensor. The three sets of sensors are used to calculate the deviation of the barrel mixing effect.

[0033] In step 2, the first layer of the detection container is provided with a spectral image sensor, and the second and third layers are respectively provided with three groups of turbidity sensors and three groups of suspended matter sensors. The spectral image sensor of the first layer is a rotary sensor, which obtains spectral images of pesticides through 360° rotation. Six sensors are provided inside the second and third layers, and the angle of each sensor is 60°, which are used to automatically calculate the pesticide parameters and display the results on the display.

[0034] In step 2, when conducting turbidity and suspended matter tests, the second and third layers are tested simultaneously and the data after the tests are completed are compared to calculate the CV value of the test results. The solution volume of each layer in the container is the same. By conducting the same test on each layer of pesticide and comparing the test results, the stability of the pesticide solution is tested.

[0035] In step three, after completing sample collection and parameter measurement, all measured parameter values, including spectral images, turbidity and suspended particle data, are recorded. The sensor is equipped with three sets of lights to judge the stability of the configured pesticide. If a green light is displayed, it is below the threshold, if a yellow light is displayed, the threshold is too high, and if a red light is displayed, the threshold is extremely high.

[0036] In step four, when judging the results, ensure that the components in the liquid medicine are evenly distributed. When the detection parameter values ​​are all within the preset threshold range, the mixed liquid medicine system is judged to be stable and uniform and can be directly used for field spraying. When the detection parameter values ​​exceed the preset threshold range, it is judged that the effect is poor.

[0037] In step five, create a report template to record the parameter comparison analysis and conclusions. The basic parameters of the spectral image are 400nm-700nm, the basic parameter of turbidity is 15NTU, and the basic parameter of suspended particles is 100,000 particles per milliliter. Give an overall assessment of the mixing effect of the pesticide solution. Compare the reflectance value of the spectral image with the preset threshold to determine whether there is a significant spectral difference. Compare the turbidity value with the basic parameter. The basic parameter is 15NTU. A turbidity value below 15NTU indicates that the solution is well mixed. Compare the particle count with the basic parameter. The basic parameter is 100,000 particles per milliliter. A count below 100,000 particles indicates that the solution is evenly mixed.

[0038] This method for rapidly detecting the effect of a tank mix of pesticide formulations collects representative samples for detection through a sampling test tube. The infrared spectrometer probe above the detection equipment automatically rotates 360 degrees above the equipment to obtain spectra at different positions inside the equipment. The analysis method of the concentration sensor is consistent with that of the suspended matter sensor. Three sensors are provided on each layer of the equipment, and three lights are corresponding to the three sensors. The stability of the configured pesticide is judged by the lighting situation, which is used to calculate the deviation and coefficient of variation. A threshold is set before the test. After the test, a green light is displayed when the value is lower than the set threshold, a yellow light is displayed when the threshold is higher, and a red light is displayed when the threshold is extremely high. When the test parameter values ​​are all within the preset threshold range, it is determined that the tank mix effect does not need to be stirred again. When the test parameter values ​​exceed the preset threshold range, the mixing formula of the tank mix liquid is adjusted. If a uniform and stable mixed liquid cannot be achieved, consider changing the type of pesticide to ensure that the ingredients in the liquid are evenly distributed, and then adjust the formula and mixing ratio of the pesticide formulation.
