Description

Technical Field

[0001] This utility model relates to the field of pesticide detection technology, and more specifically, to an outdoor pesticide detector. Background Technology

[0002] Outdoor pesticide testing is a method of quickly screening agricultural products (such as fruits, vegetables, and grains) for pesticide residues on the surface or in the shallow tissues of production sites such as farmland, orchards, and vegetable greenhouses. Its main purpose is to immediately determine whether agricultural products have the risk of exceeding pesticide residue standards, provide a rapid basis for decision-making in harvesting and distribution, and prevent agricultural products with excessive pesticide residues from entering the market. The main testing steps include sample selection, pesticide residue extraction, detection reaction, and result interpretation.

[0003] Currently, the process of extracting pesticide residues usually requires the use of disposable gloves, utility knives, measuring cups, and other tools to pick and chop agricultural products before reacting them with test reagents. However, during the above testing process, the agricultural products frequently come into contact with gloves, resulting in the removal of some pesticides from the surface. Furthermore, by using existing measuring cups to react the reagents with the crops and then allowing them to stand, the testing environment is exposed to the air, which can easily introduce external interference factors and affect the accuracy of the test results. Utility Model Content

[0004] To overcome the aforementioned shortcomings of the prior art, this utility model provides an outdoor pesticide detector to address the problems of frequent contact between agricultural products and gloves, which leads to the removal of pesticides from the surface. Furthermore, the existing method of using a measuring cup to react reagents with crops exposes the testing environment to air, easily introducing external interference factors that affect the accuracy of the test results.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an outdoor pesticide detector, including a detection bottle, a feed inlet at the top of the detection bottle, a hinge shaft welded to the outside of the feed inlet, two half-cut sealing caps fitted on the feed inlet, both half-cut sealing caps hinged to the hinge shaft, a pull ring on the outside of each half-cut sealing cap, an elastic element between the two half-cut sealing caps, a cutter on the inside of one half-cut sealing cap, and a groove corresponding to the cutter on the inside of the other half-cut sealing cap.

[0006] Preferably, the inside of the test bottle is provided with a stirring assembly, the stirring assembly including a base, the base being fixed to the bottom of the inner cavity of the test bottle, a vertical slag-blocking net being provided inside the test bottle, the upper and lower ends of the slag-blocking net being connected to the test bottle and the base respectively, a stirring rod passing through and rotating in the middle of the test bottle and the base, stirring blades being evenly distributed on the part of the stirring rod located inside the slag-blocking net, and a rotating disc being provided at the end of the stirring rod located outside the test bottle.

[0007] Preferably, the base and stirring blades are both made of silicone rubber, and the slag-blocking net is made of polyester fiber.

[0008] Preferably, the test bottle is further provided with a crushing assembly, which includes crushing halves symmetrically arranged on both sides of the inner cavity of the test bottle. A sliding rod is fixedly connected to the opposite side of the crushing halves, and a handle is fixedly connected to the end of the sliding rod away from the crushing halves. The sliding rod is slidably inserted into both sides of the test bottle, and a return spring is also sleeved on the sliding rod between the test bottle and the handle.

[0009] Preferably, a plurality of crushing teeth are distributed on the opposite sides of the two extrusion halves, the crushing teeth on the two extrusion halves are staggered, and a groove is formed in the middle of the crushing teeth.

[0010] Preferably, the bottom of the test bottle is provided with a support frame.

[0011] Preferably, the test bottle is transparent, and scale lines are provided on the outside of the test bottle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of an elastic element, allows the two semi-cut sealing caps to close and seal the inlet opening without external force, creating a relatively sealed environment for the sample and reagent reaction inside the test bottle. This reduces interference from external factors and self-oxidation and volatilization. Furthermore, by pulling the handle with the thumb and forefinger, the semi-cut sealing caps can be rotated open, allowing the agricultural product to be directly inserted into the inlet. A cutter then cuts the product into the test bottle for subsequent testing steps. This significantly reduces contact with the agricultural product, avoids the removal of pesticides from its surface, and thus improves the accuracy of the test results.

[0014] This invention uses a rotating disc to make the stirring blades rotate and stir the sample, ensuring thorough mixing of the sample and reagents and improving detection efficiency.

[0015] This invention uses repeated pressing of the handle to cause the crushing teeth on the extrusion half to squeeze each other, thus crushing the test sample. At the same time, it can be combined with a stirring component to adjust the extrusion angle, allowing the pesticides in the sample to fully react with the reagents. Attached Figure Description
