Abstract

The invention discloses a rotary positioning device and a detection system for detecting pesticide residue on the surface of fruits, belonging to the field of pesticide detection. The rotary positioning device comprises a bottom plate, a fixed mount, a movable mount and a spring, wherein the upper part of the bottom plate is provided with a bottom stand column; the fixed mount is fixedly connected with the bottom plate; the upper part of the fixed mount is provided with a through hole for exciting light to pass through; the upper part of the movable mount is provided with a roller for driving a sample to be tested to rotate while the lower part of the movable mount is provided with a sleeve matched with the bottom stand column; the sleeve is sleeved on the bottom stand column; a positioning nut is arranged on the outer side of the sleeve; and the spring is sleeved outside the sleeve and arranged between the bottom plate and the positioning nut. According to the rotary positioning device and the detection system, nondestructive detection of the pesticide residue on the surface of fruits is realized with less detection time, low detection working capacity and high detection precision.

Description

technical field [0001] The invention relates to the technical field of pesticide detection, in particular to a rotary positioning device and a detection system for detecting pesticide residues on fruit surfaces. Background technique [0002] Pesticides generally refer to the collective name of chemical agents used to prevent pests, weeds and other harmful organisms that harm crops and agricultural by-products, and are important agricultural production materials. Due to population growth and shortage of arable land resources, the demand for the production and use of pesticides in our country continues unabated. According to statistics, more than 15 provinces in my country must use pesticides in large quantities. However, due to long-term and large-scale use, small or trace amounts of pesticides remain on the surface of fruits and vegetables, which can easily cause acute or chronic poisoning to the human body. Studies have shown that long-term consumption of fruits and veget...
