Description

Technical Field

[0001] This invention relates to the technical field of efficacy testing equipment for acaricides, specifically to an efficacy testing device and method for acaricides for two-spotted spider mites. Background Technology

[0002] Acaricide efficacy testing is an important technical means to evaluate the control effect of acaricides, determine the appropriate application concentration, and analyze the characteristics of the agents. It typically involves treating target mites with different concentrations of the acaricide and judging the efficacy based on indicators such as mortality rate, knockdown rate, and persistence. Currently, in the efficacy evaluation of agricultural mites such as the two-spotted spider mite, different concentrations of acaricide solution are usually prepared artificially and added to separate test containers for testing.

[0003] However, existing acaricide efficacy testing equipment still has certain shortcomings in practical applications: On the one hand, different concentrations of pesticide solutions usually need to be manually prepared and added one by one, making it difficult to conduct simultaneous tests of multiple concentration gradients, resulting in a long test cycle and affecting detection efficiency; on the other hand, traditional methods of adding pesticide solutions can easily cause uneven diffusion of the solution inside the test container, leading to differences in the amount of pesticide applied to some mites, thus affecting the accuracy and repeatability of efficacy evaluation results. In addition, during the test, the pesticide solution can easily adhere to the inner wall of the test container or the surface of the filter structure, which not only affects subsequent observations but may also cause test residues to interfere with the data of the next set of tests.

[0004] Meanwhile, existing experimental devices usually require manual treatment of the test subjects and waste liquid after the test. The drug solution and mites are difficult to separate and collect quickly, which increases the operational burden on the test personnel and reduces the standardization of the test process.

[0005] Therefore, there is an urgent need for a device for testing the efficacy of acaricides for two-spotted spider mites, which can automatically supply different doses of the acaricide solution, uniformly diffuse the acaricide solution, clean up residues in the test chamber, and separate and recover the test subjects from the acaricide solution, so as to improve the automation level, test efficiency, and stability of test results in the acaricide efficacy evaluation process. Summary of the Invention

[0006] The purpose of this invention is to provide an efficacy testing device and method for a two-spotted spider mite acaricide, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] This invention relates to an efficacy testing apparatus and method for a two-spotted spider mite acaricide, comprising a workbench, a support frame fixedly connected to the bottom of the workbench, a support ring fixedly connected to the end of the workbench, a stirring tank fixedly connected to the inner wall of the support ring, a power unit fixedly connected to the top of the stirring tank, and a transparent test container fixedly connected to the surface of the workbench, and further comprising:

[0009] The infusion mechanism includes a drain pipe, an end of which is fixedly connected to a solenoid valve, and the output end of the solenoid valve is fixedly connected to an inlet pipe. The infusion mechanism delivers the uniformly mixed acaricide solution in the mixing tank to the corresponding transparent test tanks according to a preset dosage, so as to form a drug efficacy test environment with different concentration gradients.

[0010] The spraying mechanism includes a rotating ring, on the surface of which a spray pipe and a scraper are fixedly connected. A nozzle is fixedly connected to the surface of the spray pipe. The spraying mechanism drives the spray pipe to rotate through the rotating ring, so that the nozzle forms a circumferential spraying path. At the same time, the scraper is used to clean the residual liquid inside the transparent test tank in a synchronous manner to improve the uniformity of liquid distribution.

[0011] A storage mechanism includes a pull-down bracket, a pull-down rod hinged to the surface of the pull-down bracket, and a sealing disc hinged to the end of the pull-down rod away from the pull-down bracket. The storage mechanism is used to control the opening of the test chamber after the efficacy test is completed, so as to separate and collect the test subject from the waste liquid.

[0012] Furthermore, the surface of the workbench is provided with a storage hole, and the inner wall of the test transparent tank is connected to the inner wall of the storage hole. There are three test transparent tanks, which are arranged side by side on the surface of the workbench. The inner wall of the test transparent tank is provided with a sealing door.

[0013] Furthermore, the infusion mechanism includes a water pump, the output end of which is fixedly connected to a water pump pipe, the output end of which is fixedly connected to a rotating shaft, and a stirring frame is fixedly connected to the surface of the rotating shaft. The stirring frame is driven to rotate by the power device, so that the acaricide and water are fully mixed to form a uniform test solution.

[0014] Furthermore, the end of the rotating shaft away from the power device is rotatably connected to the inner wall of the mixing tank, the bottom of the water pump is fixedly connected to the surface of the workbench, and the ends of the water pump pipe and the drain pipe are both fixedly connected to the output end of the water pump.

[0015] Furthermore, the spraying mechanism includes a water inlet tank, a cross plate fixedly connected to the inner wall of the rotating ring, a driven ring fixedly connected to the side of the scraper away from the rotating ring, a cleaning plate fixedly connected to the surface of the driven ring, a motor fixedly connected to the top of the water inlet tank, a drive shaft fixedly connected to the output end of the motor, and a filter cylinder fixedly connected to the top of the inner wall of the transparent test tank.

[0016] Furthermore, the surface of the water inlet bucket is fixedly connected to the top of the inner wall of the test transparent tank, the inner wall of the rotating ring is slidably connected to the inner wall of the water inlet bucket, the inner wall of the driven ring is slidably connected to the inner wall of the filter cylinder, the side of the scraper away from the rotating ring is in contact with the inner wall of the filter cylinder, both sides of the cleaning plate are in contact with the outer wall of the filter cylinder and the inner wall of the test transparent tank, and the end of the drive shaft away from the motor is fixedly connected to the surface of the cross plate.

[0017] Furthermore, the storage mechanism includes a storage box, a storage slide plate slidably connected to the inner wall of the storage box, an electric telescopic rod fixedly connected to the surface of the storage box, a recycling pipe fixedly connected to the bottom of the storage box, and a collection bucket fixedly connected to the end of the recycling pipe away from the storage box.

[0018] Furthermore, the output end of the electric telescopic rod is fixedly connected to the bottom of the pull-down bracket, the outer wall of the sealing disc is hinged to the inner wall of the storage hole, the bottom of the filter cylinder is in contact with the surface of the sealing disc, the top of the storage box is fixedly connected to the bottom of the workbench, the bottom of the collection bucket is fixedly connected to the top of the inner wall of the support frame, and the inner wall of the storage box and the inner wall of the storage hole are interconnected.

[0019] Furthermore, a method for testing the efficacy of a two-spotted spider mite acaricide includes the following steps:

[0020] S1: First, add the medicine and water into the mixing tank, and then start the power unit to drive the shaft to rotate. When the shaft rotates, it will drive the mixing rack to rotate. During the rotation of the mixing rack, the medicine and water will be mixed more evenly. Next, open the sealed door and put the same number of mites into the three test transparent tanks.

[0021] S2: By using a water pump and a solenoid valve, different amounts of pesticide can be delivered to the inside of the water inlet tank. This allows for testing on mites using different amounts of pesticide. The combination of the water pump and the solenoid valve effectively delivers different amounts of pesticide to the three water inlet tanks. The amount of pesticide can be observed through the scale on the surface of the transparent test tank, thus obtaining the mite-killing effect of different amounts of pesticide and improving the efficiency of acaricide testing.

[0022] S3: When the scraper rotates, it will drive the driven ring to slide in a ring shape on the inner wall of the filter cylinder. When the driven ring slides, it will drive the cleaning plate to rotate. When the cleaning plate rotates, it will clean the inner wall of the test transparent tank and the outer wall of the filter cylinder, preventing the reagent from remaining on the inner wall of the test transparent tank and the outer wall of the filter cylinder.

[0023] S4: Finally, the medicine flows into the collection bucket through the recycling pipe, thereby collecting and separating the medicine and mites. After the mites flow into the inside of the collection slide, the staff can pull out the collection slide to clean the mites. The collection slide and the collection bucket effectively separate and collect the medicine and mites.

[0024] The present invention has the following beneficial effects:

[0025] The efficacy test of the acaricide of this invention involves first adding the acaricide and water into a mixing tank, then starting a power unit to rotate a shaft. The rotation of the shaft causes the mixing rack to rotate, further homogenizing the acaricide and water. Next, the sealed door is opened, and an equal number of mites are placed into three transparent test containers, each equipped with a graduated gauge. A water pump is then activated to extract the homogenized acaricide from the mixing tank via a water pipe. The acaricide is then transferred to a drain pipe via the water pump. Since there are three drain pipes, three solenoid valves, and three inlet pipes, one solenoid valve is opened while the other two are closed. The solenoid valve then transfers the acaricide to the inlet pipe, which in turn outputs the acaricide to a water tank. This process of transferring the acaricide... In this process, staff can determine the dosage of the pesticide according to the scale on the surface of the transparent test tank. When the pesticide delivered by the inlet pipe reaches the specified dosage, the solenoid valve is closed to stop the pesticide delivery. At this time, another solenoid valve can be opened, and the other two solenoid valves can be closed. Finally, the pesticide is delivered to another water tank through the inlet pipe. Since there are three inlet pipes and three water tanks, different dosages of pesticide can be delivered to the water tanks through the cooperation of a water pump and solenoid valves. This allows for testing on mites with different dosages of pesticide. By effectively using the cooperation of the water pump and solenoid valves, different dosages of pesticide can be delivered to the three water tanks respectively, and the dosage can be observed through the scale on the surface of the transparent test tank. This allows for obtaining the mite-killing effect of different dosages of pesticide, thereby improving the efficiency of the acaricide test.

[0026] This invention employs a spraying mechanism. As the pesticide enters the inlet tank, it simultaneously flows into four spray pipes. A motor then drives a drive shaft, which in turn rotates a cross plate. This rotation causes a rotating ring to slide in a ring shape against the inner wall of the inlet tank. The sliding ring, in turn, rotates the spray pipes and scraper. The scraper's rotation, in turn, rotates the nozzles. The pesticide flowing into the spray pipes is then sprayed outwards through the nozzles, ensuring even distribution of the pesticide onto the inner wall of the filter cartridge. The rotation of the scraper 34 pushes the pesticide on the inner wall of the filter cartridge 41, causing it to flow through the filter holes on the surface of the filter cartridge 41 to the outer wall. Finally, the pesticide flows down the surface of the filter cartridge 41 to the bottom of the inner wall of the transparent test tank, allowing mites to come into contact with the pesticide. This also helps to clean the filter cartridge. The inner wall is cleaned by the scraper rotating, which causes the driven ring to slide in a ring shape on the inner wall of the filter cartridge. As the driven ring slides, it drives the cleaning plate to rotate. The rotation of the cleaning plate cleans the inner wall of the transparent test container and the outer wall of the filter cartridge, preventing the reagent from remaining on the inner wall of the transparent test container and the outer wall of the filter cartridge. It also prevents mites from sticking to the outer wall of the filter cartridge and the inner wall of the transparent test container. Effectively, the rotating scraper causes the reagent to flow through the filter holes to the outer wall of the filter cartridge and finally to the bottom, so that the mites come into contact with the reagent. At the same time, it cleans the inner wall of the filter cartridge, preventing the reagent from remaining on the inner wall of the filter cartridge. The rotation of the cleaning plate also cleans the inner wall of the transparent test container and the outer wall of the filter cartridge of any remaining reagent, while also preventing mites from sticking to the outer wall of the filter cartridge and the inner wall of the transparent test container.

[0027] This invention utilizes a collection mechanism. After the mite test is completed, an electric telescopic rod is activated to pull the pull-down bracket downwards. As the pull-down bracket 54 moves downwards, it pulls the end of the pull-down rod 55 downwards. Since there are two pull-down rods 55 and two sealing discs 56, as the end of the pull-down rod 55 moves downwards, the other end of the pull-down rod pulls the sealing disc downwards and expands in a direction away from each other, thereby separating the surface of the sealing disc from the bottom of the filter cartridge. After the sealing disc separates from the filter cartridge, the mites and the medicine flow into the inside of the collection slide. At this time, the mites remain inside the collection slide, while the medicine flows through the filter holes into the inside of the recovery pipe. Finally, the medicine flows into the collection bucket through the recovery pipe, thus collecting and separating the medicine and mites. After the mites flow into the inside of the collection slide, the staff can pull out the collection slide to clean the mites. The collection slide and the collection bucket effectively separate and collect the medicine and mites.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-10 As shown, this invention relates to an efficacy testing device and method for a two-spotted spider mite acaricide, comprising a workbench 1, a support frame 2 fixedly connected to the bottom of the workbench 1, a support ring 3 fixedly connected to the end of the workbench 1, a stirring tank 4 fixedly connected to the inner wall of the support ring 3, a power unit 5 fixedly connected to the top of the stirring tank 4, and a transparent test container 6 fixedly connected to the surface of the workbench 1, and further comprising:

[0044] The infusion mechanism 10 includes a drain pipe 13, with a solenoid valve 14 fixedly connected to the end of the drain pipe 13, and an inlet pipe 15 fixedly connected to the output end of the solenoid valve 14. The infusion mechanism 10 delivers the acaricide solution mixed evenly in the mixing tank 4 to the corresponding transparent test tank 6 according to the preset dosage, so as to form a drug efficacy test environment with different concentration gradients.

[0045] The spraying mechanism 30 includes a rotating ring 32, on the surface of which a spraying pipe 33 and a scraper 34 are fixedly connected. A nozzle 35 is fixedly connected to the surface of the spraying pipe 33. The spraying mechanism 30 drives the spraying pipe 33 to rotate through the rotating ring 32, so that the nozzle 35 forms a circumferential spraying path. At the same time, the scraper 34 is used to clean the residual liquid inside the transparent test tank 6 to improve the uniformity of liquid distribution.

[0046] The storage mechanism 50 includes a pull-down bracket 54, a pull-down rod 55 hinged to the surface of the pull-down bracket 54, and a sealing disc 56 hinged to the end of the pull-down rod 55 away from the pull-down bracket 54. The storage mechanism 50 is used to control the opening of the test chamber after the efficacy test is completed, so that the test object and the waste liquid can be separated and collected.

[0047] The surface of the workbench 1 is provided with a storage hole. The inner wall of the test transparent tank 6 is connected to the inner wall of the storage hole. There are three test transparent tanks 6, which are arranged side by side on the surface of the workbench 1. The inner wall of the test transparent tank 6 is provided with a sealing door.

[0048] The infusion device 10 includes a water pump 11, the output end of which is fixedly connected to a water pump pipe 12, and the output end of the power device 5 is fixedly connected to a rotating shaft 16. A stirring rack 17 is fixedly connected to the surface of the rotating shaft 16. First, the medicine and water are added into the inside of the stirring tank 4. Then, the power device 5 is started to drive the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it will drive the stirring rack 17 to rotate. During the rotation of the stirring rack 17, the medicine and water will be stirred more evenly.

[0049] The end of the rotating shaft 16 away from the power unit 5 is rotatably connected to the inner wall of the mixing tank 4. The bottom of the water pump 11 is fixedly connected to the surface of the workbench 1. The ends of the water pump pipe 12 and the drain pipe 13 are both fixedly connected to the output end of the water pump 11. Next, the sealed door is opened and the same number of mites are placed inside the three transparent test tanks 6. Each of the three transparent test tanks 6 is equipped with a scale. Then, the water pump 11 is started to extract the uniformly stirred agent inside the mixing tank 4 through the water pump pipe 12. Then, the agent is transferred to the inside of the drain pipe 13 through the water pump 11. Since there are three drain pipes 13, three solenoid valves 14, and three inlet pipes 15, one of the solenoid valves 14 is opened first, while the other two solenoid valves 14 are closed. Then, the solenoid valve 14 transfers the agent to the inside of the inlet pipe 15. Then, the inlet pipe 15 outputs the agent to the inside of the water tank 31. During the process of transferring the agent... Staff can determine the dosage of the pesticide according to the scale on the surface of the transparent test tank 6. When the pesticide delivered by the inlet pipe 15 reaches the specified dosage, the solenoid valve 14 is closed to stop the pesticide delivery. At this time, another solenoid valve 14 can be opened and the other two solenoid valves 14 can be closed. Finally, the pesticide is delivered to the interior of another water inlet tank 31 through the inlet pipe 15. Since there are three inlet pipes 15 and three water inlet tanks 31, different dosages of pesticide can be delivered to the interior of the water inlet tank 31 through the cooperation of the water pump 11 and the solenoid valve 14. Thus, different dosages of pesticide can be used to test for mites. By cooperating with the water pump and the solenoid valve, different dosages of pesticide can be delivered to the three water inlet tanks 31 respectively. The dosage can be observed through the scale on the surface of the transparent test tank 6, so as to obtain the mite-killing effect of different dosages of pesticide, thereby improving the efficiency of the acaricide test.

[0050] The spraying mechanism 30 includes a water inlet tank 31. When the agent enters the water inlet tank 31, it flows into the four spray pipes 33. A cross plate 36 is fixedly connected to the inner wall of the rotating ring 32. A driven ring 37 is fixedly connected to the side of the scraper 34 away from the rotating ring 32. When the rotating ring 32 slides, it drives the spray pipes 33 and the scraper 34 to rotate. When the scraper 34 rotates, it drives the nozzle 35 to rotate. At this time, the agent flowing into the spray pipes 33 is sprayed outward through the nozzle 35, thus evenly spraying the agent onto the inner wall of the filter cylinder 41. A cleaning plate 38 is fixedly connected to the surface of the driven ring 37. A motor 39 is fixedly connected to the top of the water inlet tank 31. A drive shaft 40 is fixedly connected to the output end of the motor 39. The filter cylinder 41 is fixedly connected to the top of the inner wall of the test transparent tank 6. When the scraper 34 rotates, it drives the driven ring 37 to rotate in the filter cylinder. The inner wall of the filter cylinder 41 slides in a ring shape. When the driven ring 37 slides, it drives the cleaning plate 38 to rotate. When the cleaning plate 38 rotates, it cleans the inner wall of the transparent test tank 6 and the outer wall of the filter cylinder 41, preventing the agent from remaining on the inner wall of the transparent test tank 6 and the outer wall of the filter cylinder 41. At the same time, it prevents mites from sticking to the outer wall of the filter cylinder 41 and the inner wall of the transparent test tank 6. Effectively, during the rotation of the scraper 34, the agent flows through the filter holes to the outer wall of the filter cylinder 41 and finally flows to the bottom, allowing mites to come into contact with the agent. At the same time, it cleans the inner wall of the filter cylinder 41, preventing the agent from remaining on the inner wall of the filter cylinder 41. Also, during the rotation of the cleaning plate 38, it cleans the agent remaining on the inner wall of the transparent test tank 6 and the outer wall of the filter cylinder 41, while also preventing mites from sticking to the outer wall of the filter cylinder 41 and the inner wall of the transparent test tank 6.

[0051] The surface of the inlet tank 31 is fixedly connected to the top of the inner wall of the transparent test tank 6. The inner wall of the rotating ring 32 is slidably connected to the inner wall of the inlet tank 31. When the cross plate 36 rotates, it will drive the rotating ring 32 to slide in a ring shape on the inner wall of the inlet tank 31. The inner wall of the driven ring 37 is slidably connected to the inner wall of the filter cylinder 41. The side of the scraper 34 away from the rotating ring 32 contacts the inner wall of the filter cylinder 41. Both sides of the cleaning plate 38 are in contact with the outer wall of the filter cylinder 41 and the inner wall of the transparent test tank 6. When the scraper 34 rotates, it will push the reagent on the inner wall of the filter cylinder 41 to rotate and make the reagent pass through. The filter holes on the surface of the filter cylinder 41 flow to the outer wall of the filter cylinder 41. Finally, the medicine flows along the surface of the filter cylinder 41 into the bottom of the inner wall of the transparent test tank 6, allowing the medicine to flow through the filter holes on the surface of the filter cylinder 41 to the outer wall of the filter cylinder 41, and finally into the bottom of the inner wall of the transparent test tank 6, so that the mites come into contact with the medicine. At the same time, the inner wall of the filter cylinder 41 can also be cleaned. The end of the drive shaft 40 away from the motor 39 is fixedly connected to the surface of the cross plate 36. At this time, the motor 39 is started to drive the drive shaft 40 to rotate. When the drive shaft 40 rotates, it will drive the cross plate 36 to rotate.

[0052] The storage mechanism 50 includes a storage box 51, a storage slide plate 52 slidably connected to the inner wall of the storage box 51, an electric telescopic rod 53 fixedly connected to the surface of the storage box 51, a recycling pipe 57 fixedly connected to the bottom of the storage box 51, and a collection bucket 58 fixedly connected to the end of the recycling pipe 57 away from the storage box 51. When the sealing disc 56 separates from the filter cartridge 41, mites and medicine will flow into the interior of the storage slide plate 52. At this time, the mites will remain inside the storage slide plate 52, while the medicine will flow through the filter holes into the interior of the recycling pipe 57. Finally, the medicine will flow into the interior of the collection bucket 58 through the recycling pipe 57, thereby collecting and separating the medicine and mites. After the mites flow into the interior of the storage slide plate 52, the staff can pull out the storage slide plate 52 to clean the mites. The storage slide plate 52 and the collection bucket 58 effectively separate and collect the medicine and mites.

[0053] The output end of the electric telescopic rod 53 is fixedly connected to the bottom of the pull-down bracket 54. The outer wall of the sealing plate 56 is hinged to the inner wall of the storage hole. The bottom of the filter cylinder 41 is in contact with the surface of the sealing plate 56. After the mite test is completed, the electric telescopic rod 53 is activated to pull the pull-down bracket 54 downward. When the pull-down bracket 54 moves downward, it will pull the end of the pull-down rod 55 downward. Since there are two pull-down rods 55 and two sealing plates 56, when the end of the pull-down rod 55 moves downward, the other end of the pull-down rod 55 will pull the sealing plate 56 downward and expand in a direction away from each other, thereby separating the surface of the sealing plate 56 from the bottom of the filter cylinder 41. The top of the storage box 51 is fixedly connected to the bottom of the workbench 1. The bottom of the collection bucket 58 is fixedly connected to the top of the inner wall of the support frame 2. The inner wall of the storage box 51 is connected to the inner wall of the storage hole.

[0054] A method for testing the efficacy of a two-spotted spider mite acaricide, comprising the following steps:

[0055] S1: First, add the medicine and water into the mixing tank 4, and then start the power unit 5 to drive the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it will drive the mixing rack 17 to rotate. During the rotation of the mixing rack 17, the medicine and water will be mixed more evenly. Next, open the sealed door and put the same number of mites into the three test transparent tanks 6.

[0056] S2: By cooperating with the water pump 11 and the solenoid valve 14, different amounts of pesticide can be transferred to the inside of the water inlet tank 31. This allows for testing on mites using different amounts of pesticide. The water pump 11 and the solenoid valve 14 can effectively deliver different amounts of pesticide to the three water inlet tanks 31. The amount of pesticide can be observed through the scale on the surface of the transparent test tank 6, thus obtaining the mite-killing effect of different amounts of pesticide and improving the efficiency of the acaricide test.

[0057] S3: When the scraper 34 rotates, it will drive the driven ring 37 to slide in a ring shape on the inner wall of the filter cylinder 41. When the driven ring 37 slides, it will drive the cleaning plate 38 to rotate. When the cleaning plate 38 rotates, it will clean the inner wall of the test transparent tank 6 and the outer wall of the filter cylinder 41 to prevent the reagent from remaining on the inner wall of the test transparent tank 6 and the outer wall of the filter cylinder 41.

[0058] S4: Finally, the medicine flows into the collection bucket 58 through the recycling pipe 57, thereby collecting and separating the medicine and mites. After the mites flow into the storage slide plate 52, the staff can pull out the storage slide plate 52 to clean the mites. The storage slide plate 52 and the collection bucket 58 effectively separate and collect the medicine and mites.

[0059] In use, first add the reagent and water into the mixing tank 4, then start the power unit 5 to drive the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it will drive the stirring rack 17 to rotate. During the rotation of the stirring rack 17, the reagent and water will be mixed more evenly. Next, open the sealed door and put the same number of mites into the three transparent test tanks 6. Each of the three transparent test tanks 6 is equipped with a scale. Then, start the water pump 11 to extract the evenly mixed reagent inside the mixing tank 4 through the water pump pipe 12. Then, the water pump 11 will transfer the reagent to the drain pipe 13. Since there are three drain pipes 13, solenoid valves 14 and liquid inlet pipes 15, open one of the solenoid valves 14 first. The other two solenoid valves 14 are closed. Solenoid valve 14 then transfers the reagent to the inlet pipe 15, which in turn outputs the reagent to the water inlet tank 31. During reagent transfer, the operator can determine the dosage based on the scale on the surface of the transparent test tank. Once the designated dosage is reached, solenoid valve 14 is closed to stop the transfer. At this point, another solenoid valve 14 can be opened, and the other two solenoid valves 14 are closed. Finally, the reagent is transferred to the water inlet tank 31 via inlet pipe 15. Since there are three inlet pipes 15 and three water inlet tanks 31, different dosages can be transferred using the cooperation of the water pump 11 and solenoid valves 14. The pesticide is transferred into the inlet tank 31, allowing for testing on mites using different dosages. Simultaneously, as the pesticide enters the inlet tank 31, it flows into the four spray pipes 33. At this point, the motor 39 starts, driving the drive shaft 40 to rotate. This rotation of the drive shaft 40 causes the cross plate 36 to rotate, which in turn causes the rotating ring 32 to slide in a ring shape on the inner wall of the inlet tank 31. This sliding motion of the rotating ring 32 causes the spray pipes 33 and the scraper 34 to rotate. The rotation of the scraper 34 then causes the nozzle 35 to rotate. The pesticide flowing into the spray pipes 33 is then sprayed outwards through the nozzle 35, ensuring even distribution of the pesticide onto the inner wall of the filter cartridge 41. The rotation of the scraper 34 also pushes... The reagent on the inner wall of the filter cartridge 41 rotates, causing it to flow through the filter holes on the surface of the filter cartridge 41 to the outer wall of the filter cartridge 41. Finally, the reagent flows down the surface of the filter cartridge 41 into the bottom of the inner wall of the transparent test tank 6, allowing mites to come into contact with the reagent. Simultaneously, the inner wall of the filter cartridge 41 is cleaned. As the scraper 34 rotates, it drives the driven ring 37 to slide in a ring shape on the inner wall of the filter cartridge 41. The sliding of the driven ring 37 drives the cleaning plate 38 to rotate, cleaning the inner wall of the transparent test tank 6 and the outer wall of the filter cartridge 41. This prevents reagent residue from remaining on the inner wall of the transparent test tank 6 and the outer wall of the filter cartridge 41, and also prevents mites from sticking to the outer wall of the filter cartridge 41 and the inner wall of the transparent test tank 6.After the mite test is completed, the electric telescopic rod 53 is activated to pull the pull-down bracket 54 downwards. As the pull-down bracket 54 moves downwards, it pulls the end of the pull-down rod 55 downwards. Since there are two pull-down rods 55 and two sealing discs 56, as the end of the pull-down rod 55 moves downwards, the other end of the pull-down rod 55 pulls the sealing disc 56 downwards and expands it in a direction away from each other, thus separating the surface of the sealing disc 56 from the bottom of the filter cartridge 41. After the sealing disc 56 separates from the filter cartridge 41, the mites and the pesticide flow into the inside of the collection slide plate 52. At this time, the mites remain inside the collection slide plate 52, while the pesticide flows through the filter holes into the inside of the recovery pipe 57. Finally, the pesticide flows through the recovery pipe 57 into the inside of the collection tank 58, thus collecting and separating the pesticide and mites. After the mites have flowed into the inside of the collection slide plate 52, the staff can pull out the collection slide plate 52 to clean the mites.
