Abstract

This utility model belongs to the field of pesticide residue detection technology in rice, and particularly relates to a sampling device for pesticide residue detection in rice. It includes a base, a pesticide residue detector mounted on the top surface of the base, a stirring drum fixed to the base via support legs, a stirring assembly inside the stirring drum, a sampling tube connected to the side wall of the stirring drum, and a thin tube connected to the sampling tube. A slide is mounted on the top surface of the base, with a slider sliding on the slide. The slider has a clamping and positioning assembly for holding a cuvette, and a driving assembly for driving the slider to reciprocate and rotate the cuvette. This utility model can achieve uniform mixing of the extract and reagents, improving sampling accuracy and detection effect, reducing human error, and increasing detection efficiency.
