Description

Infrared particle counting instrument

Technical Field

The utility model relates to a seed count field among the agroforestry articles for use especially relates to an infrared several appearance.

Background

The existing seed counting is usually carried out in a manual counting mode, the counting mode is long in time consumption, and when the sample inspection amount is large, errors are easy to occur. Also there is the mode that adopts seed number board to carry out the number on the market, but number board also mainly relies on manual operation, if when carrying out extensive examination to hundreds of strains, can consume a large amount of manual works, and the cost is higher, and efficiency is not high, makes mistakes easily moreover. In addition, there are also devices such as automatic particle counter with higher automation in the market, and when counting particles by using the existing particle counter, counting errors are often caused because seeds pass through the counting device at the same time.

There are also devices and apparatuses for counting seeds in published patent documents, for example, chinese patent with publication number CN 106275640B discloses a planar laser counting device including a semiconductor laser, an optical lens group, a counting box and a photoelectric receiver. A point light source emitted by the semiconductor laser forms a one-dimensional line light source through the optical lens group, and the photoelectric receiver performs plane omnibearing dead-angle-free counting. The counting principle is that when the particles pass through a laser plane (one-dimensional line light source) in the particle counting chamber, the line light source is shielded, the photoelectric receiver detects the signal change of the line light source, and the change signal is processed to determine the number of the passing particles and count and record the number of the passing particles. Theoretically, this scheme can take notes all quantity through the seed of laser plane, however, to non-circular seed, its transversely through the laser plane and the vertical line source size that shelters from through the laser plane are different, can lead to the count deviation, consequently, when adopting this kind of counting mode to count to non-circular seed, can't ensure the accuracy of count result.
