The food nutrient content detection device according to claim 1, wherein: the sample receiving device (2) comprises a conveying platform (21), a butt joint flat plate (22) and a glass ware (23), wherein the glass ware (23) is placed on the upper surface of the butt joint flat plate (22), the butt joint flat plate (22) is placed on the surface of the conveying platform (21), and the outer wall of the glass ware (23) is in contact with the edge of the fluorescent smear (119).

8. A detection method of a food nutrient content detection device is characterized by comprising the following steps:

s1, placing food to be detected on a containing tray main body (151), and driving a cutting belt (36) to rotate through a limiting gear (35) to complete pressing and cutting of food samples so that the food samples enter a quantitative distribution box (12);

s2, firstly, the food samples are subjected to solid-liquid separation, and the cleaning plate (18) can scrape the food samples in the tray main body (151) out of the residual solid samples;

s3, the scraped food sample directly falls into the receiving box body (121), and when the weight of the food sample gradually increases, the conical discharging block (126) positioned below the receiving box body is moved out of the built-in connecting pipe (127) to wait for the sample to be refilled;

s4, the sample discharged from the built-in connecting pipe (127) is in contact with the edge of the glass ware (23) and the fluorescent smear (119), so that the glass ware (23) loaded with the food sample is marked, and finally the food sample in the glass ware (23) is detected by using a double-condensed urea method.
