Sample crushing device for pesticide residue detection

Abstract

The utility model relates to the technical field of pesticide residue detection, in particular to a sample crushing device for pesticide residue detection, which comprises a bottom box and a support plate, the upper end of the bottom box is fixedly connected with the support plate, an extrusion device is arranged in the bottom box, and the support plate is fixedly connected with the bottom box. And the upper end of the supporting plate is fixedly connected with a cylinder, the upper end of the cylinder is provided with a crushing device, and the left side of the cylinder is fixedly communicated with a feeding port. Through cooperation of the crushing device and the barrel and rotation of a first crushing roller and a second crushing roller in different directions, fruit samples are crushed, the crushing effect is improved, through cooperation of the extrusion device and the box body, in the sliding plate movement process, a scraping plate is pushed to be tightly attached to the bottom of the box body under the elastic effect of a spring, and the crushing effect is improved. Fruits are squeezed while the sliding plate moves, juice flowing out of the squeezed fruits is discharged through the liquid outlet, the juice is increased, and the detection accuracy is improved.
