Identification and detection device for pollution-free vegetables

Abstract

The invention aims to solve the identification problem of pollution-free vegetables, and discloses an identification and detection device for pollution-free vegetables. The device comprises an observation cylinder, wherein a second end cover and a first end cover are mounted at the left end and the right end of the observation cylinder respectively, a connecting rope is connected between the second end cover and the observation cylinder, a thermometer is fixedly installed on the inner side face of the second end cover, a water tank is fixedly installed in the middle of the upper surface of the observation cylinder, a water pump is fixedly installed on the upper side of the water tank, a fourth guide pipe is communicated between the water pump and the water tank, the water pump is communicated with a third guide pipe, a material pumping pump is fixedly mounted in the middle of the lower surface of the observation cylinder, a second guide pipe is communicated between the material pumping pump and the observation cylinder, a material storage box is fixedly installed on the lower side of the material pumping pump, and a first guide pipe is communicated between the material storage box and the material pumping pump. By reasonably washing and collecting soil on vegetables, whether the vegetables are pollution-free or not can be visually detected.

Description

technical field [0001] The invention relates to the field of vegetable detection, in particular to an identification and detection device for pollution-free vegetables. Background technique [0002] Pollution-free vegetables refer to vegetables that do not contain harmful substances that are not allowed to be contained in the vegetable products, and the content of other substances is controlled within the allowable range. In a broad sense, pollution-free vegetables are a general term for vegetables that are safe, high-quality, and nutritious. According to the regulations of China Green Food Development Center, pollution-free vegetables are usually divided into two grades: AA grade and A grade. [0003] The planting of pollution-free vegetables does not use chemically synthesized fertilizers, but mainly fertilizes with animal manure. Among them, the use of animal manure for fertilization will cause more microorganisms to exist in the soil, which is good for vegetables and wi...

Problems solved by technology

[0003] The planting of pollution-free vegetables does not use chemically synthesized fertilizers, but mainly fertilizes with animal manure. Among them, the use of animal manure for fertilization will cause more microorganisms to exist in the soil, which is good for vegetables and will not be affected by fertilizers. Damage to vegetables, but from the outside, it is not easy to see the difference between vegetables, it is not easy to identify pollution-free vegetables, and it is inconvenient to choose. Therefore, it is urgent to design an identification and detection device for pollution-free vegetables to solve the problem of vegetable identification. question
