Description

Technical Field

[0001] This utility model belongs to the field of agricultural product testing technology, and in particular relates to a device for detecting drug residues in agricultural products. Background Technology

[0002] In agricultural production, after pesticides are applied, some pesticides remain directly or indirectly in grains, vegetables, fruits, and livestock products. Of the pesticides applied to crops, some adhere to the crops, while some are scattered in the soil, atmosphere, and water environment. Some of the pesticides remaining in the environment are absorbed by plants. Residual pesticides can directly reach humans and animals through plant fruits, water, or the atmosphere, or ultimately be transferred to humans and animals through the environment and food chain. Therefore, it is necessary to use pesticide residue detection equipment to detect the degree of pesticide residues.

[0003] The most common portable pesticide residue testing equipment is a portable case, such as the PR-12N pesticide residue detector. However, when using this equipment, it is still necessary to select internal accessories according to the procedure, and after use, the accessories need to be cleaned and put back in place, which is inconvenient. Utility Model Content

[0004] This utility model provides a drug residue detection device for agricultural products, aiming to solve the problem mentioned in the background art that existing common portable drug residue detection devices still require selecting internal accessories according to the process to work, and the accessories need to be cleaned and put back after use, which is inconvenient.

[0005] To solve the above problems, this utility model is implemented as follows: an agricultural product pesticide residue detection device, comprising: a housing; a rubber bladder installed inside the housing via a connecting plate for storing agricultural product soaking solution; a dropper fixed to the bottom of the rubber bladder and extending outside the housing for discharging the agricultural product soaking solution, the dropper being fitted with a mounting bracket; a guide tube installed on the top of the rubber bladder for assisting in adding agricultural product samples; a protective cover detachably installed on the top of the guide tube for sealing the guide tube; and a testing component disposed on the mounting bracket for detecting pesticide residues.

[0006] Preferably, the test assembly includes a bottom cover threaded onto the outside of the mounting bracket; and a test strip for detecting pesticide residues, which is attached to the bottom cover by an adhesive sheet and is located directly below the dropper.

[0007] Preferably, a colorimetric card for comparing pesticide residue levels is installed on the outer wall of the housing, and the colorimetric card is covered with a waterproof membrane for isolating wastewater.

[0008] Preferably, an extension rod is installed on the top inner wall of the protective cover, and a push plate that can contact the inner wall of the guide cylinder is fixed at the bottom of the extension rod. The push plate is provided with mesh holes and is used to push the agricultural product sample stuck in the guide cylinder.

[0009] Preferably, a threaded cylinder is fixedly sleeved on the outside of the guide cylinder, the protective cover is threadedly sleeved on the outside of the threaded cylinder, and handles for providing gripping points are installed on both sides of the housing, and the handles are covered with anti-slip pads.

[0010] Preferably, the mounting bracket has an opening at the bottom of the dropper, which allows the agricultural product soaking solution to pass through, and anti-slip strips are installed on the outer walls of both the protective cover and the bottom cover.

[0011] Preferably, a hanging rope is installed on the top of the protective cover, and adjustment ports are provided on both sides of the housing to allow the rubber bladder to pass through, with the rubber bladder extending outside the housing through the adjustment ports.

[0012] Preferably, the mounting bracket is provided with a vent hole for balancing air pressure, the connecting plate is provided with an operating port, and a plug is installed in the operating port by internal thread.

[0013] Compared with related technologies, the agricultural product pesticide residue detection equipment provided by this utility model has the following beneficial effects:

[0014] Compared to existing technologies, the agricultural product pesticide residue detection equipment provided in this solution uses a rubber bladder to store the soaking solution of agricultural products. This design not only ensures the sealing and durability of the soaking solution but also allows users to easily squeeze the rubber bladder to discharge some of the soaking solution for testing. Simultaneously, the design of the feed tube and protective cap allows agricultural product samples to smoothly and accurately enter the rubber bladder and mix with the soaking solution, thereby improving the convenience and accuracy of sample addition. The dropper and mounting rack in the equipment provide users with the possibility of precisely controlling the discharge rate and volume of the soaking solution. The dropper design allows users to adjust the discharge rate of the soaking solution as needed, while the mounting rack not only supports and fixes the dropper but also provides a stable mounting platform for the testing components. This design makes the entire detection equipment structure more compact and stable, improving the accuracy and reliability of the detection. The introduction of the testing components makes the detection process more intuitive and convenient. The test strips absorb the soaking solution discharged from the dropper and display the pesticide residue status in the agricultural products through specific chemical reactions or biometric technologies. Users can directly observe the color change or pattern display on the test strips to determine the degree of pesticide residue, thus quickly obtaining the test results.

[0015] In addition, the equipment is also designed with auxiliary components such as colorimetric cards, waterproof membranes, push plates, extension rods, handles, and anti-slip mats. The introduction of these components further improves the practicality and convenience of the equipment. The design of the colorimetric cards and waterproof membranes makes the test results more intuitive and easier to understand. The push plates and extension rods solve the problem of agricultural product samples getting stuck in the guide tube. The handles and anti-slip mats provide users with a more comfortable grip experience. The design of the hanging rope allows users to easily carry the entire testing equipment.
