Multi-hopper walnut sorting device and sorting system

The invention discloses a hopper walnut sorting device and a sorting system, and relates to the technical field of sorting. The multi-hopper walnut sorting device comprises a sorting box and a hopper mechanism. The hopper mechanism comprises a first hopper, a second hopper and a third hopper, and the first hopper, the second hopper and the third hopper are sequentially arranged at the bottom of the sorting box and used for receiving meat-embedded materials, walnut kernels and impurities in the walnut materials correspondingly. A recognition mechanism, a first air injection mechanism and a second air injection mechanism are arranged in the sorting box, the first air injection mechanism and the second air injection mechanism are both in communication connection with the recognition mechanism, and the recognition mechanism is used for recognizing the meat-embedded materials, the walnut kernels and the impurities in walnut materials and can control the first air injection mechanism to blow the meat-embedded mater
