Description

Technical Field

[0001] The invention belongs to the field of agricultural product quality detection equipment, and in particular relates to a sampling device for agricultural product quality detection. Background Art

[0002] With the development of the economy and society, food safety is becoming increasingly important to the general public. Agricultural products are essential to daily meals, but modern agricultural production requires the use of large amounts of pesticides and fertilizers to ensure high yields. To ensure food safety, agricultural product testing is essential before agricultural products are released to the market. Existing agricultural product testing devices directly insert samples into agricultural products such as potatoes, apples, and peaches. Since the surfaces of the agricultural products are not cleaned, residual pesticides on the surface may affect the test results. Secondly, existing agricultural product testing devices only sample the agricultural products once, and this single sampling may also affect the accuracy of the test results.
