Description

Technical Field

[0001] The utility model relates to the technical field of corn seed production, in particular to a screening device for corn seed production. Background Art

[0002] The screening device for corn seed production is a device specially used for corn seed screening. It can help farmers and seed producers improve seed quality, thereby increasing the yield and quality of crops. The device classifies seeds according to size, shape, density and other characteristics through a series of screening processes, removes impurities and bad seeds, and ensures the purity and quality of seeds. The device can screen seeds according to their shape and density to further ensure the quality of seeds to meet the needs of different seed production. The entire screening process can be automated, greatly improving screening efficiency and accuracy. In general, the screening device for corn seed production is a very important agricultural equipment, which can help farmers and seed producers improve seed quality, thereby increasing the yield and quality of crops. Through precise screening and classification, the device ensures the purity and quality of seeds, providing reliable guarantees for agricultural production.

[0003] According to the search of China Utility Model Publication No.: CN210965828U, a screening device for corn seed production is disclosed, 1. Through the setting of the screening box, screen, vibrator, cloth bag, fan and air diffuser, corn seeds are put into the screening box, and then the first vibrator is started to vibrate, and the seeds with smaller particles fall from the mesh of the screen, and then the fan is started to blow air to blow the dust on the surface of the seeds into the cloth bag, thereby achieving a double effect of screening seeds and removing dust. 2. Through the setting of the baffle net and the second vibrator, the baffle net and the sieve have the same aperture, which are used to prevent seeds with full particles from being accidentally discharged from the screening box. The second vibrator is started to vibrate, which can shake off the seeds with smaller particles, thereby leaving the seeds with full particles on the surface of the baffle net.
