Worm-eaten sunflower seed sorting unit

The invention relates to a worm-eaten sunflower seed sorting unit, which includes driving devices, sunflower seed delivery devices, manipulator sorting devices, visual identifying devices, air injection sorting devices and spraying cleaning devices. According to the invention, worn-eaten sunflower seeds are identified through methods of machine vision and image processing, and are efficiently sorted through the delivery devices and sorting devices; seed turning devices can be used for turning over all the seeds accurately; the adopted two sets of independent image acquisition systems can be used for image acquisition of two arc characteristic faces of sunflower seeds in the same batch, and guarantee that all the seeds with worm-eaten characteristics are identified; the adopted two sets of independent and different worn-eaten sunflower seed sorting mechanisms matched with two sets of independent visual identifying systems can be used for sorting the identified worm-eaten sunflower seeds; therefore, the worm-eaten sunflower seed sorting unit has the advantages of excellent sorting effect and universality as well as high working efficiency.
