[0002] Implanting pesticide strips into trees is an effective means of controlling tree diseases and pests. By measuring the dissolution rate and extent of pesticide strips under certain conditions, the effectiveness of releasing drugs within the tree can be evaluated, thereby ensuring the quality and efficacy of pesticides. Accurate and reliable measurement results are of great significance for optimizing pesticide strip formulations and improving drug performance.

However, this method makes it difficult for the strips to sink to the bottom of the beaker, and it cannot effectively simulate the melting and transformation of pesticide strips.

[0004] Therefore, how to effectively simulate the melting transformation of pesticide strip agents and improve the accuracy of pesticide strip agent melting transformation determination is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0037] The following combination Figures 1 to 5 This application will be described in further detail.

[0038] This application discloses a device for determining the melting point of pesticide strips.

[0039] A device for determining the melt flow of pesticide strips. (Reference) Figure 1 and Figure 2 The device includes a housing 1 and several melting cylinders 2. The housing 1 can hold an aqueous solution for dissolving pesticide strips. The upper part of the housing 1 is open, and the several melting cylinders 2 are fixedly connected together and placed in the aqueous solution inside the housing 1. Each melting cylinder 2 is provided with a sieve plate 21 for supporting the pesticide strips. Each melting cylinder 2 holds one pesticide strip. The several melting cylinders 2 can be completely immersed in the aqueous solution inside the housing 1. In this embodiment, the number of melting cylinders 2 is 3, while in other embodiments, it is 2 or 4, depending on the number of pesticide strips measured each time. The pesticide strip melting test device can effectively hold the aqueous solution and place the strips through several melting cylinders 2. The sieve plate 21 inside the melting cylinders 2 supports the pesticide strips. The multiple melting cylinders 2 are fixedly connected and completely immersed in the aqueous solution, so that the pesticide strips remain in the middle of the aqueous solution during the melting process, preventing the pesticide strips from sinking to the bottom and improving the accuracy and reliability of the test.

[0040] Reference Figure 2 and Figure 3The melting and transformation cylinder 2 includes a cylinder 22 and a sieve plate 21. The cylinder 22 has openings at both ends. In this embodiment, the cylinder 22 is cylindrical, while in other embodiments, it is square. The shape of the sieve plate 21 is determined according to the shape of the cylinder 22. The sieve plate 21 is fixed in the middle of the cylinder 22. The sieve plate 21 can be fixed to the cylinder 22 by welding, bonding, or screw fastening. The sieve plate 21 has several first water-permeable holes 211. The diameter of the first water-permeable holes 211 is smaller than the diameter of the pesticide strip. The pesticide strip is supported on the sieve plate 21 located in the middle of the cylinder 22. The pesticide strip diffuses from the middle of the solution in the tank 1 to the surrounding area, which helps to effectively simulate the melting and transformation of the pesticide strip and improve the accuracy of the pesticide strip melting and transformation measurement.

[0041] Reference Figure 2 and Figure 3 The cylinder 22 is provided with several second water-permeable holes 221 for water permeation. These holes 221 are distributed on both sides of the sieve plate 21. The holes 221 allow the aqueous solution in the chamber 1 to flow fully into the melting cylinder 2 and come into contact with the pesticide strips. This ensures that the pesticide strips are in full contact with the aqueous solution during the melting process, improving the accuracy of the pesticide strip melting test. The cylinder 22 and sieve plate 21 of the melting cylinder 2 are made of stainless steel, which gives the device good corrosion resistance and service life. This ensures that the pesticide strips are not affected by material corrosion during the melting test, improving the accuracy of the test results.

[0042] Reference Figure 4 and Figure 5 The melting point determination device also includes a lifting mechanism 3 for raising and lowering the melting point cylinder 2. The lifting mechanism 3 includes a lifting frame 31 and a drive assembly 32. The lifting frame 31 includes a support part 311 located inside the housing 1 for supporting several melting point cylinders 2, and a transmission part 312 located on both sides outside the housing 1 for transmitting power to the drive assembly 32. The support part 311 and the transmission part 312 are fixedly connected. The melting point cylinder 2 can be lowered into the housing 1 or extended out of the housing 1 by the lifting mechanism 3, which can realize the smooth raising and lowering of the melting point cylinder 2, thereby ensuring the stability of the pesticide strip during the determination process, improving the accuracy and reliability of the determination, and improving the convenience of operating the melting point cylinder 2 and reducing the labor intensity of the test personnel.

[0043] Reference Figure 5The drive assembly 32 includes two drive motors 321 and two transmission screws 322. The two drive motors 321 are fixedly installed on both sides of the housing 1, and the two transmission screws 322 are rotatably installed on the housing 1 at positions corresponding to the drive motors 321. The transmission screws 322 are connected to the output shafts of the drive motors 321. A nut 3121 is installed on the transmission part 312, and the transmission screws 322 are connected to the nut 3121. The two drive motors 321 drive the two transmission screws 322 to rotate, and the transmission screws 322 drive the nut 3121 and the transmission part 312 to rise and fall. The transmission part 312 drives the lifting frame 31 to rise and fall smoothly, thereby realizing the precise control of the melting cylinder 2 in the aqueous solution, improving the accuracy and reliability of pesticide strip melting determination, and reducing the labor intensity of the test personnel.

[0044] Reference Figure 1 The melting point determination device also includes a weighing component 4, which is used to weigh the aqueous solution in the tank 1. The weighing component 4 includes four weighing sensors 41, which are supported and installed on the support legs 11 at the bottom of the tank 1. The weighing component 4 can accurately weigh the aqueous solution in the tank 1, thereby accurately controlling the amount of pesticide strip agent melting point solution used and improving the accuracy of melting point determination.

[0045] Reference Figure 1 The bottom of the housing 1 is provided with a water valve 5 for draining the aqueous solution of the housing 1. In this embodiment, the water valve 5 is a manual water valve 5, while in other embodiments of this application, an electric water valve 5 is used, which can facilitate automatic control. The water valve 5 at the bottom of the housing 1 facilitates the rapid drainage of the aqueous solution after the measurement is completed, which is convenient for subsequent testing of the aqueous solution and improves the ease of use and work efficiency of the device.

[0046] The working process of a pesticide strip melting test device is as follows: During the initial test, the water valve 5 is closed, the support part 311 of the lifting frame 31 is positioned at the top of the housing 1, and the three melting cylinders 2 are placed on the support part 311. The three pesticide strips are placed on the sieve plates 21 of the three melting cylinders 2 respectively. An aqueous solution of a certain temperature is added to the housing 1, and the weighing component 4 weighs the aqueous solution. Once the aqueous solution reaches the predetermined weight, water addition is stopped, the drive motor 321 is started to rotate, driving the transmission screw 322 to rotate. The transmission unit 312 drives the support part 311 of the lifting frame 31 to descend to the bottom of the box 1, so that the three melting cylinders 2 and the pesticide strip are completely immersed in the aqueous solution. The drive motor 321 is de-energized and stops working. After the pesticide strip is immersed in the aqueous solution for a predetermined time, the drive motor 321 is started to rotate, so that the support part 311 rises to the top of the box 1. The pesticide strip is observed to see if it has melted or softened. If it has completely melted or softened, it is qualified. The water valve 5 is opened to drain the aqueous solution containing the pesticide strip into the test container for subsequent testing.

[0047] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
