AI Technical Summary
While existing watermelon seed screening equipment can grade seeds by size, it cannot effectively screen for seeds with internal quality problems, such as shriveled or poorly developed seeds, resulting in some unqualified seeds not being identified.
A device including a screening mechanism and a water treatment mechanism was designed. A rotary motor drives a screw rod to stir the seeds and separate them by hydraulic force. According to the difference in seed density, a nozzle pushes the floating seeds to the retrieval port. A slider drives a retrieval plate to retrieve the unqualified seeds. High-quality seeds slide through an inclined water tank to a conveyor belt and are collected. The water collection tank recovers excess water, forming a water recycling system.
This technology enables accurate separation of high-quality and substandard seeds based on seed density, improving screening efficiency, ensuring seed quality, and guaranteeing the screening effect on the internal quality of seeds.
