Description

Technical Field

[0001] The utility model relates to the field of agricultural product detection equipment, in particular to a grinding device for agricultural product detection with a multi-stage crushing structure. Background Art

[0002] Grinding equipment for agricultural product testing can grind agricultural product samples (such as grains, beans, nuts, fruits and vegetables, etc.) into a fineness suitable for analytical testing. This is very important for maintaining sample uniformity and improving analytical accuracy. At the same time, ground agricultural product samples can be used for various component analyses, such as nutrients (protein, fat, fiber, minerals, etc.), additives, pesticide residues, microbial contamination, etc. These analyses help evaluate the quality of agricultural products.

[0003] At present, most grinding equipment used in agricultural product testing is designed with only a set of simple crushing structures. This single crushing structure often cannot fully crush the samples when processing agricultural product samples, resulting in uneven and incomplete sample crushing. This insufficient crushing will have a negative impact on subsequent test results and reduce the accuracy and reliability of the analysis.

[0004] Therefore, in view of the fact that most of the grinding equipment used in the above-mentioned agricultural product testing is only equipped with a set of simple crushing structures in design, which leads to the situation that the agricultural product samples are not crushed evenly and thoroughly, a grinding equipment for agricultural product testing with a multi-stage crushing structure can be designed. Through the belt drive structure and the rotating structure, the agricultural products can be crushed and ground while avoiding the problem of uneven and thorough crushing of agricultural product samples.
