Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, and in particular to a pesticide residue detection and sampling device. Background Technology

[0002] The development of agricultural industrialization has made agricultural production increasingly reliant on exogenous substances such as pesticides, antibiotics, and hormones. The irrational use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer safety and impacting agricultural trade. Therefore, it is necessary to test for pesticide residues to prevent adverse consequences caused by excessive pesticide residues.

[0003] A search revealed a public disclosure (announcement) number: CN214149894U, which discloses a pesticide residue detection sampling device. This device solves the problem of inaccurate pesticide detection caused by rinsing pesticide samples with water. It includes an outer cylinder with a through-groove at its top. An inner cylinder, penetrating the through-groove, is located inside the outer cylinder. A retaining seat, engaging with the inner cylinder, is located at the bottom of the outer cylinder. An inlet is located on one side of the inner cylinder, and a movable door, movably connected to the inlet, is located on the outer wall of the inner cylinder. A pressing mechanism is located in the middle of the inner cylinder, and a spraying mechanism is located on one side of the pressing mechanism. Through the combined action of the pressing and spraying mechanisms, water is sprayed evenly from the nozzle, ensuring thorough contact between the sample and the water. This allows for soaking the sample, accelerating the mixing of pesticides and water, and ensuring complete removal of pesticide residues, thereby improving the accuracy of the detection and the experiment.

[0004] While the above methods can speed up the thorough mixing of pesticides and water, the number of crops that can be washed at one time is limited. In addition, pesticide residues adhering to the surface of crops require external assistance to be removed, and the detection process is relatively complicated, making it difficult to quickly detect and intuitively observe the test results. Utility Model Content

[0005] The main purpose of this utility model is to provide a pesticide residue detection and sampling device. By setting up a sampling unit, it solves the problem that the number of crops that can be washed at one time is limited, and that pesticide residues attached to the surface of crops require external force to be removed. By setting up a detection unit, it solves the problem that the detection process is relatively complicated and difficult to detect quickly and intuitively observe the detection results.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pesticide residue detection sampling device includes a concave detection box, a sampling unit disposed inside the detection box, and a detection unit disposed on the side of the sampling unit.

[0008] The sampling unit includes a detachable plate detachably disposed at the top of the middle part of the detection box, a sliding component disposed inside the detachable plate, and a sample storage component disposed at the bottom of the sliding component.

[0009] The detection unit includes rotating components located on both sides inside the detection box, and a discharge component located at the bottom of the rotating components.

[0010] Preferably, the sliding component in the sampling unit includes a convex groove formed at the bottom of the detachable plate, a movable plate disposed inside the convex groove, and a drain frame fixedly connected to the bottom of the movable plate.

[0011] Preferably, the sample storage component in the sampling unit includes a convex disk detachably disposed inside a detachable plate, two driven shafts rotatably connected to the bottom end of the convex disk, and a plurality of flexible blocks disposed on the surface of the driven shafts.

[0012] Preferably, the sampling unit further includes two handles fixedly connected to the top of the detachable plate, and a flushing pipe disposed inside the detection box and facing the leakage frame.

[0013] Preferably, the rotating component in the detection unit includes two rotating motors fixedly connected to one side of the detection box, a rotating shaft disposed at the output end of the rotating motor and extending into the inside of the detection box, a baffle fixedly connected to the surface of the rotating shaft, a flexible plate fixedly connected to one side of the baffle, and a detection groove formed by the baffle and the inner wall of the detection box in a trapezoidal shape.

[0014] The two baffles and the inner wall of the bottom center of the detection box form a temporary storage groove.

[0015] Preferably, the discharge component in the detection unit includes a discharge pipe disposed on one side of the bottom of the detection tank and extending to the outside of the detection box, and a valve fixedly connected to one end of the discharge pipe.

[0016] Preferably, the detection unit further includes a dosing hole located at the top of the detection box and connected to the detection slot, and two observation windows located on one side of the detection box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] I. In this utility model, by setting up a sampling unit, the detachable plate can be removed, and multiple movable plates in the convex groove can be separated from the detection box. Then, the movable plates can be slid away from the convex groove, and the convex plate can be removed to place the crops in the drainage frame. Similarly, it is convenient and quick to remove the crops. Then, the movable plates can be inserted back into the convex groove. Multiple movable plates can be placed in the convex groove, so multiple crops can be placed. Then, the crops are washed by the flushing pipe. The water flow moves and drives the crops to rotate, which also drives the driven shaft and flexible block to rotate, further accelerating the flow rate of water near the crops, thereby separating pesticide residues on the crops and improving the accuracy of subsequent detection.

[0019] II. In this utility model, by setting up a detection unit, after the crops are cleaned, the rotating motor is started to drive the rotating shaft to rotate, which in turn drives the baffle and flexible plate to rotate, so that the temporary storage tank and the detection tank are connected. The water resources containing pesticide residues in the temporary storage tank enter the detection tank, and the detection reagent is added through the dosing hole. The detection results can be directly observed through the observation window. After the detection is completed, the valve is started to discharge the mixture through the discharge pipe. This eliminates the need to collect the water resources containing pesticide residues and re-detect them, thus optimizing the convenience of detection. Attached Figure Description
