Scanning device for plant root system

The utility model discloses a scanning device for plant root systems, which relates to the technical field of agriculture and forestry research and novel intelligent detection and solves the problems that the root system must be pulled out when the root system growth condition is detected in the prior art, and thus, the plant is damaged, the research is inconvenient and the entire growth process of the same plant can not be detected. The utility model is characterized in that an upper end opening of a transparent shell body 4 is sheathed on the excircle surface on the lower side of each of the fixed bases 1-6 of a horizontal rotary /vertical lifting mechanism 1, the lower end of each of the vertical sliding rack gears 1-7 of the 1 is connected to the upper end face of a lamp cover 5, the upper end face of the inner side of the 5 is connected to the upper end face of a fixed support 2-1 of a horizontal straight line moving mechanism, and the lower end of a straight line moving slide block 2-2 on the lower end of the 2 is connected to the bottom face of a chromatic CCD video camera head 3. The utility model directly samples the plant root systems with images in a contactless mode and does not hurt the plant root systems, with the advantages of high measuring precision, simple structure and easy use and maintenance.
