specific Embodiment approach

[0053] The edge of the lower shell 5, the edge of the lower partition 17, and the edge of the upper slot 16 form a continuous lower edge 20;

[0054] The edge of the upper casing 4, the edge of the upper partition 7, and the edge of the lower slot 18 form a continuous upper edge 19;

[0055] The lower edge 20 is fixedly connected with a rubber sealing strip 21 , and the upper edge 19 is provided with a sealing groove 22 for inserting the rubber sealing strip 21 .

[0056] Through the above technical solution, through the cooperation of the rubber sealing strip 21 and the sealing groove 22, the rubber sealing strip 21 can be embedded in the sealing groove 22 during the process of assembling the upper casing 4 and the lower casing 5 to form a sealing structure, so that The solution can be prevented from seeping out from the gap between the upper case 4 and the lower case 5 .

[0057] As an improved specific implementation,

[0058] The upper casing 4 is provided with an upper ...

Abstract

The invention discloses a device for detecting pesticide residues in food, which comprises a soaking box, an input pipe and an output pipe; the soaking box includes an upper shell and a lower shell, and two half cavities are formed after the upper shell and the lower shell are combined A complete accommodating cavity; a rotating rod is provided in the through hole, a first external thread is provided on the rotating rod, a first external thread is provided on the rotating rod, and a first external thread is provided on the through hole to cooperate with the first external thread The first internal thread of the rotating rod forms a screw structure; one end of the rotating rod is located in the accommodating cavity, and the other end passes through the perforation. A conduction hole is provided, and a pull rod is arranged in the conduction hole, one end of the pull rod is connected to the rolling plate in rotation, and the other end extends out of the soaking tank, and the pull rod is provided with an injection hole; the output pipe is socketed On the outlet pipe, the inlet pipe is used to be inserted into the opening of the injection hole on the side of the pull rod facing away from the rolling disc. This allows for automated soaking before being transported to the testing facility.

Description

technical field [0001] The invention relates to a food testing device, more specifically to a device for testing food pesticide residues. Background technique [0002] The phenomenon that a part of the pesticide remains directly or indirectly in grains, vegetables, fruits, livestock products, aquatic products, soil and water after the application of pesticides in agricultural production. [0003] The amount of pesticides used in agricultural products in my country remains high, and the unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting the safety of consumers, and in severe cases, it will cause consumers to become ill, develop abnormally, and even directly lead to poisoning die. Excessive pesticide residues will also affect the trade of agricultural products. Countries all over the world attach great importance to the issue of pesticide residues, and have set increasingly strict limits for pesticide r...
