Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide residue testing technology, specifically to a pesticide residue testing device for agricultural products. Background Technology
[0002] Nowadays, when people grow vegetables and other edible crops, they often spray pesticides on them to ensure their healthy growth and prevent the occurrence of pests, diseases, or weeds, thereby ensuring the quality of these plants. However, after harvesting, pesticide residues are very likely to remain on these plants. If people eat them, it will affect their health over a long period of time. Therefore, pesticide residue testing is required before these plants enter the market.
[0003] Currently, when testing agricultural products for pesticide residues, the testing equipment retains residue from the previous batch of agricultural products. This causes the previous batch of agricultural products to mix with newly added agricultural products, resulting in inaccurate testing and affecting the quality of pesticide residue testing. Furthermore, when testing agricultural products with little juice, they need to be mixed with water to form a liquid, but this can easily lead to uneven mixing of agricultural products and water, affecting the pesticide residue test results. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an agricultural product pesticide residue testing device, which solves the problems of residual agricultural products from the previous test, causing the previous batch of tested agricultural products to mix with newly added agricultural products, resulting in inaccurate agricultural product testing, and uneven mixing of agricultural products with water when mixing agricultural products for testing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A pesticide residue testing device for agricultural products includes a support plate and a support frame fixedly connected to the top of the support plate. A testing barrel is fixedly connected between the two sides of the inner cavity of the support frame via a connecting plate. A motor is fixedly connected to the top of the support plate. The output shaft of the motor is fixedly connected to a rotating rod via a coupling. One end of the rotating rod passes through the testing barrel and extends into its interior. A rotating pipe is fixedly connected to the end of the rotating rod extending into the testing barrel. One end of the rotating pipe passes through the support frame and extends above it. A rotating opening adapted to the rotating pipe is provided at the top of the support frame. A water pipe is rotatably connected to the end of the rotating pipe extending above the support frame via a sealed bearing. Water spray heads are connected to all four sides of the rotating pipe and inside the testing barrel. A water storage tank is fixedly connected to the bottom of the support plate. A drain pipe is connected to the bottom of the inner cavity of the testing barrel. One end of the drain pipe passes through the water storage tank and extends into its interior.
[0006] Preferably, a plurality of fixed sleeves are fixedly connected to the surface of the rotating rod and inside the inspection barrel, and agitation plates are fixedly connected to both sides of the surface of the fixed sleeves.
[0007] Preferably, L-shaped plates are fixedly connected to the lower sides of both sides of the rotating rod surface.
[0008] Preferably, an electric telescopic rod is fixedly connected to the top of the support frame and behind the rotating tube through an opening, and a limit frame is fixedly connected to the telescopic end of the electric telescopic rod.
[0009] Preferably, both sides of the limiting frame are slidably connected to sliding rods through openings, and one end of each sliding rod is fixedly connected to a clamping plate.
[0010] Preferably, a spring is fixedly connected to the surface of the sliding rod between the limiting frame and the clamping plate, and a pesticide residue test card is provided between the two clamping plates.
[0011] Beneficial effects
[0012] This utility model provides a device for testing pesticide residues in agricultural products. Compared with existing technologies, it has the following advantages:
[0013] (1) This utility model allows water to flow through a water pipe, which in turn allows water to enter a rotating pipe. The rotating pipe is then rotated by a motor, which in turn drives the rotating rod to rotate. The rotating rod in turn drives multiple spray nozzles on the rotating pipe to rotate. As the multiple spray nozzles rotate, they spray water, which effectively sprays water onto the inner wall of the test barrel. This facilitates cleaning of the inside of the test barrel and effectively removes any residual agricultural products, ensuring the quality of the next agricultural product pesticide residue test.
[0014] (2) This utility model drives multiple fixed sleeves to rotate by rotating rod, which in turn drives the stirring plate to rotate, so that the multiple stirring plates mix the agricultural products and water evenly. Then, the electric telescopic rod is controlled to drive the limiting frame to move downward, and the limiting frame will drive the pesticide residue test card to move downward into the test bucket, so that the pesticide residue test of agricultural products can be carried out well.

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a pesticide residue testing device for agricultural products, including a support plate 1 and a support frame 2 fixedly connected to the top of the support plate 1. A testing barrel 3 is fixedly connected between the two sides of the inner cavity of the support frame 2 via a connecting plate. A motor 4, a servo motor, is fixedly connected to the top of the support plate 1 and electrically connected to an external power source. It is controlled by a control switch. The output shaft of the motor 4 is fixedly connected to a rotating rod 5 via a coupling. One end of the rotating rod 5 passes through the testing barrel 3 and extends into the interior of the testing barrel 3. A sealed rotating port adapted to the rotating rod 5 is provided at the bottom of the testing barrel 3. One end of the inner part is fixedly connected to a rotating pipe 6. One end of the rotating pipe 6 passes through the support frame 2 and extends to the top of the support frame 2. The top of the support frame 2 is provided with a rotating port that matches the rotating pipe 6. The end of the rotating pipe 6 that extends to the top of the support frame 2 is rotatably connected to a water pipe 7 through a sealed bearing. Spray nozzles 8 are connected to all four sides of the surface of the rotating pipe 6 and inside the test tank 3. A water storage tank 9 is fixedly connected to the bottom of the support plate 1. A drain pipe 10 is connected to the bottom of the inner cavity of the test tank 3. One end of the drain pipe 10 passes through the water storage tank 9 and extends into the interior of the water storage tank 9. L-shaped plates 13 are fixedly connected to the lower sides of both sides of the rotating rod 5.
[0022] It should be noted that water pipe 7 is connected to an external water source for water to flow through it.
[0023] Furthermore, in order to agitate the agricultural products and water evenly, several fixed sleeves 11 are fixedly connected to the surface of the rotating rod 5 and inside the inspection barrel 3, and agitating plates 12 are fixedly connected to both sides of the surface of the fixed sleeves 11.
[0024] Furthermore, to facilitate the testing of pesticide residues in agricultural products, an electric telescopic rod 14 is fixedly connected to the top of the support frame 2 and behind the rotating tube 6 through an opening. The electric telescopic rod 14 is electrically connected to an external power source and controlled by a control switch. A limit frame 15 is fixedly connected to the telescopic end of the electric telescopic rod 14. Sliding rods 16 are slidably connected to both sides of the limit frame 15 through openings. A clamping plate 18 is fixedly connected to one end of the sliding rod 16. A spring 17 is fixedly connected to the surface of the sliding rod 16 between the limit frame 15 and the clamping plate 18. A pesticide residue test card 19 is set between the two clamping plates 18. The pesticide residue test card 19 is a test paper made of cholinesterase, which is highly sensitive to organophosphorus and carbamate pesticides, and a colorimetric reagent.
[0025] It should be noted that there is a water outlet pipe connected to the lower side of one side of the water storage tank 9, which makes it convenient to drain the cleaning water in the water storage tank 9.
[0026] In use, pull the two clamping plates 18 to both sides and place the pesticide residue test card 19 between the two clamping plates 18. The force of the spring 17 causes the two sliding rods 16 to drive the two clamping plates 18 to clamp and fix the pesticide residue test card 19. The agricultural products to be tested are crushed into a pulp and put into the test bucket 3. Then, a quantitative proportion of water is added to the test bucket 3. The motor 4 drives the rotating rod 5 to rotate. The rotating rod 5 will drive the multiple stirring plates 12 to rotate through multiple fixed sleeves 11, so that the multiple stirring plates 12 will stir and mix the agricultural products. Then, stop stirring and control the electric telescopic rod 14 to extend and drive the limiting frame 15 to move downward. The limiting frame 15 will drive the pesticide residue test card 19 to extend into the test bucket 3, and the agricultural products are tested through the pesticide residue test card 19.
[0027] By controlling the retraction of the electric telescopic rod 14, the limiting frame 15 is moved upward. The limiting frame 15 will move the pesticide residue test card 19 upward. By introducing external water into the water pipe 7, water is added into the rotating pipe 6. The motor 4 is controlled again to drive the rotating rod 5 to rotate. The rotating rod 5 will drive the rotating pipe 6 to rotate, so that the multiple water spray heads 8 on the rotating pipe 6 will spray water while rotating to clean the inner wall of the test barrel 3. At the same time, the rotating rod 5 will drive the L-shaped plate 13 to rotate, and the L-shaped plate 13 will coat the inner wall of the test barrel 3. By opening the valve, the cleaning water in the test barrel 3 is discharged into the water storage tank 9 through the drain pipe 10.
