Plant specimen sampling detector
Technical Field
The invention relates to a detection machine, in particular to a detection machine for sampling a plant specimen.
Background
The plant specimen is one of the powerful means for solving the teaching aid of botany. When we say a plant in class, it is preferable to have a living body of the plant in order to enhance understanding. However, some plants are regional and seasonal, and if plant specimens are available, the limitation of regional and seasonal is not caused. Meanwhile, the plant specimen is convenient for storing the shape and the color of the plant, so that the plant specimen can be observed and researched again in the future. A few plant specimens also have collection value.
And (3) detection: the specified technical performance indexes of a certain object (gas, liquid and solid) are tested and tested by a specified method. The method is suitable for quality assessment in various industries, such as civil and architectural engineering, water conservancy, food, chemistry, environment, machinery and the like.
Because present when going on the record data to the plant specimen through the detector, can not press from both sides the plant specimen that needs detect and press from both sides the fixed data that lead to detecting of the time-out plant specimen because of external factors skew position and have the deviation great to and can not adjust the height and detect, lead to the data comparison simplification that detects out, nevertheless when placing the deposit to the plant specimen, not deposit at the eminence and lead to the plant specimen to regain the tide unable use.
Therefore, it is urgently needed to develop a plant specimen sampling detector which can clamp and fix a plant specimen to prevent a detection offset position, can adjust the height to detect and can avoid the plant specimen from storing moisture regain, so as to overcome the defects that in the prior art, when the plant specimen to be detected cannot be clamped and fixed to cause detection, the deviation of the detection data of the plant specimen is large due to the offset position of an external factor, the height cannot be adjusted to detect, the detected data is relatively simple, and the plant specimen cannot be stored at a high place to cause the moisture regain of the plant specimen to be used.
