Description

Technical Field

[0001] The present invention relates to the technical field of agricultural products, and specifically to a device for detecting pesticide residues in agricultural products and its usage method. Background Technique

[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties in various regions. The state stipulates that primary agricultural products refer to plants, animals, and their products obtained in agricultural activities, excluding various processed products.

[0003] Existing pesticide detections of agricultural products are all carried out through detectors. However, before detection, the fetched agricultural products need to be stirred, then taken out, and chemical reagents for reaction are added, and then put into the detector for detection, resulting in the complication of the technological process. In addition, each stirring can only be carried out singly, resulting in the inability to stir multiple agricultural products simultaneously, and the need to replace the detection tube with liquid each time during detection, which is rather troublesome. Summary of the Invention

A stirring and liquid inlet device is arranged on the top of the detector, and a continuous detection device is arranged in the detection chamber of the detector. The stirring and liquid inlet device consists of a support mechanism, a cover mechanism, and a driving mechanism.

[0008] The driving mechanism includes a circular column and a servo motor. The output end of the servo motor is fixedly connected with a first gear. The surface of the first gear is symmetrically meshed with second gears. The surfaces of the second gears are symmetrically and fixedly sleeved with rotating rods. Stirring mechanisms are arranged on the surfaces of the rotating rods. Circular grooves are symmetrically and fixedly formed on the surface of the circular column, and electromagnetic nozzles are symmetrically and fixedly communicated with the bottom of the circular column.

[0009] The stirring mechanism includes a sleeve. Sleeve plates are symmetrically and fixedly sleeved on the upper and lower ends of the sleeve. Interlaced blades are symmetrically and fixedly connected to the opposite surfaces of the sleeve plates.

[0010] The continuous detection device includes a fixed plate. On both sides and in the middle of the surface of the fixed plate, a first chute and a second chute are respectively and fixedly opened. A battery panel is fixedly arranged at the bottom of the fixed plate. Miniature electric telescopic rods are fixedly connected to the inner walls of the first chute and the second chute. The output ends of the miniature electric telescopic rods are fixedly connected with push plates. A plurality of grooves are opened on the surface of the fixed plate. Tensioning mechanisms are fixedly connected to the inner cavities of the plurality of grooves. The output ends of the tensioning mechanisms are fixedly connected with push plates. Slide rails are symmetrically and fixedly connected to both sides of the fixed plate.

[0011] Preferably, the tensioning mechanism includes a sleeve fixed to the bottom of the inner cavity of the groove. A telescopic rod is slidably sleeved in the inner cavity of the sleeve. A spring is fixedly connected between the bottom of the telescopic rod and the inner wall of the sleeve.

[0012] Preferably, the support mechanism includes a sleeve disk rotatably sleeved on the surface of the rotating rod. A connecting plate is fixedly connected to the surface of the sleeve disk. One end of the connecting plate is fixed to the surface of the circular column.

[0013] Preferably, the capping mechanism includes two outer caps rotatably sleeved on the surface of the circular column through hinges. Arc-shaped grooves are symmetrically and fixedly opened on the surface of the outer caps. Handles are symmetrically and fixedly connected to the tops of the arc-shaped grooves.

[0014] Preferably, the circular column is rotatably sleeved on the top of the detector. The servo motor is fixed on the top of the sleeve disk. The rotating rod is located in the inner cavity of the circular groove. The electromagnetic nozzle is in communication with the inner cavity of the circular groove.

[0015] Preferably, the fixed plate, the battery panel and the slide rails are slidably sleeved in the inner cavity of the detection chamber of the detector. The surface of the push plate fits with the inner cavities of the first chute and the second chute. The limiting plate is slidably sleeved in the inner cavities of the first chute, the second chute and the groove.

[0016] Preferably, both ends of the sleeve plate fit with the inner cavity of the circular groove. The sleeve is fixed on the surface of the rotating rod.

[0017] The present invention also discloses an agricultural product pesticide residue detection device, and its usage method includes the following steps:

[0018] S1. Stirring: By matching the arc-shaped groove with the rotating rod, hold the handle and open the outer cover through the hinge. Then, put different agricultural products into the inner cavity of the circular groove. Next, close the cover mechanism and start the servo motor. The output end of the servo motor drives the first gear to engage and rotate with the second gear, and drives the sleeve to rotate through the rotating rod, so that the blades on the relatively arranged sleeve plates crush the agricultural products. After stirring is completed, open the cover mechanism again, put the reaction chemical agents into the inner cavity of the circular groove respectively, and stir again to make them evenly mixed;

[0019] S2. Continuous detection: Then, open the electromagnetic nozzle, so that the electromagnetic nozzle injects the liquid in the inner cavity of the circular groove into the first detection tube in the inner cavities of the second chute and the first chute, and start the detector for detection. After the detection is completed, when the second detection is required, start the micro electric telescopic rod. The telescopic end of the micro electric telescopic rod drives the push plate to push the detection tube into the inner cavities of the first chute and the second chute. The generated force will cause the detection tube to squeeze the limit plate, so that the limit plate slides in the inner cavity of the sleeve through the elastic force generated by the telescopic rod and the spring, so that the limit plate retracts, and the first detected detection tube slides out from the surface of the limit plate. After it loses the extrusion force, the telescopic rod connected to the spring will reset the limit plate, and the subsequent detection tube will be blocked by the limit plate again, and the micro electric telescopic rod will also stop extending, so that the port of the detection tube is exactly aligned with the outlet of the electromagnetic nozzle, and continuous detection can be carried out.

[0020] Beneficial effects

[0021] The present invention provides an agricultural product pesticide residue detection device and its use method. Compared with the prior art, it has the following beneficial effects:

[0022] 1. For the agricultural product pesticide residue detection device and its use method, by matching the arc-shaped groove with the rotating rod, hold the handle and open the outer cover through the hinge. Then, put different agricultural products into the inner cavity of the circular groove. Next, close the cover mechanism and start the servo motor. The output end of the servo motor drives the first gear to engage and rotate with the second gear, and drives the stirring mechanism to crush the agricultural products through the rotating rod. After stirring is completed, open the cover mechanism again, put the reaction chemical agents into the inner cavity of the circular groove respectively, and stir again to make them evenly mixed. Through the stirring of multiple circular grooves, the integration of stirring and detection can simplify the process and solve the problem of simultaneously stirring and detecting different agricultural products that cannot be stirred simultaneously.

[0023] 2. The agricultural product pesticide residue detection device and its usage method drive the sleeve to rotate through a rotating rod, so that the sleeve plate rotates relative to the blades arranged in a staggered manner to crush the agricultural products. By increasing the stirring area and the same-sized gaps, the agricultural products can be broken more evenly during stirring.

[0024] 3. The agricultural product pesticide residue detection device and its usage method start the micro electric telescopic rod. The telescopic end of the micro electric telescopic rod drives the push plate to push the detection tube into the inner cavities of the first chute and the second chute. The generated force will cause the detection tube to squeeze the limit plate, so that the limit plate slides in the inner cavity of the sleeve through the elastic force generated by the telescopic rod and the spring, so that the limit plate retracts, and the first detected detection tube slides out from the surface of the limit plate. After it loses the extrusion force, the telescopic rod connected by the spring will reset the limit plate, and the subsequent detection tubes will be blocked by the limit plate again, and the micro electric telescopic rod will also stop extending, so that the port of the detection tube is exactly aligned with the outlet of the electromagnetic nozzle. Continuous detection is achieved through multiple stored detection tubes, avoiding the troublesome problem of replacing the detection tubes with liquid during detection.

[0039] Please refer to Figure 1 , an embodiment of the present invention provides a technical solution: an agricultural product pesticide residue detection device, and its usage method includes the following steps:

[0040] S1. Stirring: By matching the arc-shaped groove 222 with the rotating rod 233, hold the handle 224 and open the outer cover 221 through the hinge 223. Then put different agricultural products into the inner cavity of the circular groove 232. Then close the cover mechanism 22 and start the servo motor 235, so that the output end of the servo motor 235 drives the first gear 236 to engage and rotate with the second gear 237. Drive the sleeve 2341 to rotate through the rotating rod 233, so that the opposite blades 2343 of the sleeve plate 2342 crush the agricultural products. After stirring is completed, open the cover mechanism 22 again, and put the reacted chemical agents into the inner cavity of the circular groove 232 respectively, and stir again to make them blend evenly;

[0041] S2. Continuous detection: Then open the electromagnetic nozzle 238, so that the electromagnetic nozzle 238 injects the liquid in the inner cavity of the circular groove 232 into the first detection tube in the inner cavities of the second chute 34 and the first chute 33, and start the detector 1 for detection. After the detection is completed, when a second detection is required, start the micro electric telescopic rod 310, so that the telescopic end of the micro electric telescopic rod 310 drives the push plate 35 to push the detection tube in the inner cavities of the first chute 33 and the second chute 34. The generated force will cause the detection tube to squeeze the limit plate 39, so that the limit plate 39 slides in the inner cavity of the sleeve 381 by the elastic force generated by the telescopic rod 382 and the spring 383, so that the limit plate 39 retracts, and the first detected detection tube slides out from the surface of the limit plate 39. After losing the extrusion force, the telescopic rod 382 connected to the spring 383 will reset the limit plate 39, and the subsequent detection tubes will be blocked by the limit plate 39 again, and the micro electric telescopic rod 310 will also stop extending, so that the port of the detection tube is exactly aligned with the outlet of the electromagnetic nozzle 238, and continuous detection can be carried out.

[0042] Further, the solar panel 32 is electrically connected to the micro electric telescopic rod 310 through a wire to control the start of the micro electric telescopic rod 310. The first chute 33 is different from the second chute 34, and the push plates 35 in the inner cavities of the first chute 33 and the second chute 34 are also different. The second chute 34 is a cross-shaped chute, and there are two push plates 35 in the inner cavity of the second chute 34 and they are the same as each other. In addition, the positions of the grooves 37, the tensioning mechanism 38 and the limiting plate 39 on the surface of the fixing plate 31 are also different. Moreover, since the circular column 231 is rotatably sleeved on the top of the detector 1, it can be removed when detecting different types of agricultural products. After the circular groove 232 is cleaned with clean water, it can be used again. Then, the gap between the limiting plate 39 and the micro electric telescopic rod 310 can store five test tubes, so that five different agricultural products can be continuously detected.

[0043] Further, the detector 1 is developed based on the enzyme inhibition principle and the photoelectric colorimetry principle. Under certain conditions, organophosphorus and carbamate pesticides have an inhibitory effect on the normal function of cholinesterase, and the inhibition rate is positively correlated with the concentration of pesticides. Under normal circumstances, the enzyme catalyzes the hydrolysis of the neurotransmission metabolite acetylcholine, and its hydrolysis product reacts with the chromogenic agent to produce a yellow substance. The change value of the absorbance at 412 nm with time is measured by a spectrophotometer, and the inhibition rate is calculated. Whether there is residue of organophosphorus or carbamate pesticides in the sample can be judged through the inhibition rate.
