Detection tube special for ecological microscopic grain storage image acquisition

The invention provides a detection tube special for ecological microscopic grain storage image acquisition. The detection tube special for ecological microscopic grain storage image acquisition comprises a tube body for accommodating image acquirer, a cone connected with the front end of the tube body and conveniently inserted into a deep grain pile layer, an image acquisition window formed in the side wall of the tube body, a mirror surface reflection part embedded into the tube body and used for reflecting an ecological microscopic grain storage image to the image acquirer and a transparent cover body covering the image acquisition window. The ecological microscopic image acquirer can be conveniently inserted into the positions different in depth of a grain pile, ecological images of different layers of the grain pile are acquired, and the ecological microscopic image acquirer can be prevented from being damaged in the grain pile due to side pressures different in degree. The detection tube special for ecological microscopic grain storage image acquisition is simple in structure and convenient to operate and is suitable for the field of analysis and detection of a deep-layer ecological grain storage environment.
