Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pesticide detection, especially to a multiple residual pesticide detector. BACKGROUND

[0002] The pesticide detector is a device for rapidly detecting the pesticide residue in food, water, soil and other samples. It qualitatively or quantitatively analyzes the pesticide residue by chemical, biological or physical methods to ensure food safety and environmental health.

[0003] The electrochemical sensor is usually composed of a working electrode, a counter electrode and a reference electrode. The working electrode reacts with the pesticide to generate an electrical signal. The counter electrode provides a current loop. The reference electrode provides a stable potential reference.

[0004] In the prior art, although a certain pesticide content detection effect can be achieved in use, the existing pesticide detector lacks the function of convenient detection of multiple pesticide contents, resulting in a lack of effective detection means when detecting pesticide residues on the surface of plants, so that the content of the pesticide cannot be effectively measured, affecting the subsequent work. In view of this, we propose a multiple residual pesticide detector to solve the above problems. SUMMARY

Then the water pump is started to transfer the water in the water tank into the box body through the transmission pipe. At this time, the lifting groove is located at the bottom of the box body. During the soaking process, the motor one drives the stirring bracket to rotate to accelerate the precipitation of the pesticide. Then the motor two drives the gear to move in cooperation with the rack to lift the lifting groove. The plant is separated from the water. After a certain period of time, the electrochemical sensor is started to detect the pesticide content in the water. Then the data is transmitted to the upper end of the display screen. After detection, the control valve is opened to discharge the water. The lifting groove falls to the lowest point. Then the water is added into the box body. Then the above operation is repeated. The overall multiple pesticide content detection effect can be achieved. The device is simple in design, reliable in work and high in practicability.
