Abstract

The invention discloses a raw grain insect detection apparatus and method. The apparatus comprises a grain-insect screening and separating device, a weighing device, an insect collecting device, an electrostatic dedusting device, a machine visual device, a control unit, and a data processing unit. The grain-insect screening and separating device separates raw grains and insects by adopting a cyclone sieve and has the characteristics of high efficiency and convenience in discharging. The detection apparatus is self-cleaned through an electrostatic dedusting mode, and at the same time, insects and dust are separated. A phase locking technology is adopted, and image collection of a camera and synchronous phase locking of a light source are realized. Under the situation that a conventional camera is used, the signal-noise ratio and time resolution are greatly improved. A weighing apparatus is used, and the data can be analyzed more comprehensively.

Description

technical field [0001] The invention relates to the technical field of pest detection devices, in particular to a raw grain pest detection device and method. Background technique [0002] China is a big country of grain production, and the safe storage of grain is of great significance. At present, the grain loss due to insect pests is as high as 11%, which also affects the quality of grain. Therefore, it is very necessary to detect food pests in time and accurately, and to predict the changing trend of food pests. [0003] The traditional detection methods of raw grain pests include the sampling method and the trapping method. According to the provisions in GB / T29890-2013 of "Technical Specifications for Grain and Oil Storage", the entrapment detection method is not used to determine the grade of insect food. Insect food classification and grade indicators not only need to count the number of live insects, but also need the weight of grain samples. [0004] At present, ...
