Technical Field

The invention relates to the technical field of agricultural product detection, in particular to an embedded type segmented sampling device for agricultural product detection.

Background

The development of agricultural industrialization makes the production of agricultural products depend on exogenous substances such as pesticides, antibiotics and hormones. For a long time, the use amount of agricultural chemicals in agricultural product production in China is high, and the unreasonable use of the agricultural chemicals can lead to the overproof pesticide residues in the agricultural products and influence the edible safety of consumers; when serious, the disease is caused, the development is abnormal, and even the poisoning and death are directly caused. Meanwhile, the pesticide residue exceeding standard also influences the normal export of agricultural products. Therefore, the problem of pesticide residue is highly emphasized in all countries in the world, and increasingly strict limit standards are established for pesticide residue in various agricultural and sideline products, so that the export of agricultural products in China faces a severe challenge.

When detecting agricultural products, an embedded sectional sampling device for detecting agricultural products is mostly adopted as in patent application No. CN201821092150.X, wherein the embedded sectional sampling device comprises a bracket, a detection platform, an embedded server, a controller, a communication module and an optical detection module, wherein the detection platform, the embedded server, the controller, the communication module and the optical detection module are arranged on the bracket; the optical detection module comprises a light source and a spectrometer; the embedded server is electrically connected with the controller, and the controller is connected with the optical detection module through a communication module; at least one cuvette groove is arranged on the detection platform, and the cuvette grooves are arranged in a single row; the detection platform is characterized in that a sliding rail is horizontally arranged on the support, the detection platform can horizontally move along the sliding rail, and a rocking handle is arranged on one side of the support. According to the invention, a plurality of cuvette grooves capable of moving horizontally are arranged, so that samples at a plurality of parts of an agricultural product can be detected simultaneously. The agricultural product detection device is simple in structure and convenient and fast to operate, and can acquire multiple groups of data without replacing instruments, so that the detection time of agricultural products is short, and the numerical value is accurate.

In the agricultural product processing procedure, especially at the in-process that the grain detected, adopt traditional sampler, when the sampler inserted grain, the grain that gets into at first is the outermost end, and after grain entered fully, inside grain then can not get into, and the scope that leads to taking a sample can only be the outermost grain that has the within range, leads to the sample effect to have the limitation.

Therefore, in view of the above, research and improvement are made for the existing structure and defects, and an embedded segmented sampling device for agricultural product detection is provided, so as to achieve the purpose of higher practical value.
