Bee pollen automatic screening device and screening method

Abstract

The invention belongs to the technical field of machine vision, mechanical design and automatic control and relates to an automatic bee pollen screening device and a screening method. The device comprises an automatic feeding module, a dispersion shaping module, a visual inspection module and a sorting dust removal module. Bee pollen to be sorted is poured into a storage barrel of the automatic feeding module; the bee pollen is supplied to a V-shaped groove plate of the dispersion shaping module through an eccentric vibration motor, performs climbing movement on the V-shaped groove plate, is uniformly dispersed, falls on a conveying belt to be shaped and then moves forwards at a constant speed; image acquisition is performed through an image acquisition unit of the visual inspection module; image information is processed through built-in computer software and then transmitted to a programmable logic controller (PLC) to be controlled so as to control the actions of the eccentric vibration motor and a spray nozzle, and the bee pollen is screened. By means of the automatic bee pollen screening device and the screening method, the problems that small-particle bee pollen is prone to being broken, irregular in shape, difficult to disperse and sort and not obvious in color difference are solved, and the sorting speed is increased under the condition that the sorting accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical fields of machine vision, mechanical design and automatic control, and relates to a bee pollen automatic screening device and screening method, in particular to a bee pollen feeding method, image processing algorithm, screening method and sorting device. Background technique [0002] my country is a big producer and consumer of bee pollen, especially rape bee pollen. In 2013, the output of rapeseed bee pollen remained at 1787 tons. With the increase of demand for bee pollen, its output has shown a rising trend in recent years. Due to the restriction of rapeseed planting area and planting area and the randomness of bee collection behavior, the harvested rapeseed bee pollen will be mixed with other bee pollen. Different varieties of bee pollen have different health benefits, so the purity of bee pollen is the key factor to ensure its efficacy. Since bee pollen may contain impurities such as moldy particles, gravel...

AI Technical Summary

Problems solved by technology

However, because bee pollen is extremely fragile, this screening method will cause the suction pipe of the solenoid valve to be blocked, which will affect the color sorting effect, and its low processing capacity (about 0.68kg / h) and complicated processing mechanism limit the popularization and application.
