Free identification instrument

The invention relates to the technical field of variety identification instruments, and particularly discloses a variety identification instrument, which comprises an identification instrument main body, the device further comprises a glass carrier plate. The number of the camera assemblies is two; according to the variety identification instrument, airflow is output to wheat seeds on the surface of the glass carrier plate through the arranged arrangement mechanism, so that the wheat seeds are flatly laid on the surface of the glass carrier plate by utilizing the ejected airflow to be matched with vibration of the glass carrier plate, and when the arrangement mechanism sprays air, the wheat seeds can be uniformly distributed on the surface of the glass carrier plate. The sprayed airflow is controlled to swing front and back and left and right so as to cooperatively treat the surfaces of the wheat seeds facing the airflow, mutual adhesion of the wheat seeds is avoided, meanwhile, residual water films and water
