[0033] Working principle: When in use, the peony seeds to be shelled are poured into the hopper 21, and the peony seeds fall on the screen 22 below in sequence, and fall on the guide plate II 24 and the guide plate I 23 below respectively after being screened by the small mesh and the large mesh of the screen 22 from top to bottom, and fall into the lower opening component 3 after being guided by the guide plates I 23 and II 24; after being screened and diverted by the feed component 2, the peony seeds are diverted into large peony seeds and small peony seeds, and the large peony seeds continue to move downward into the gap between the pressing wheel I 31 and the arc-shaped knife plate I 33, and are pressed by the pressure wheel 21. The rotation of the pressing wheel Ⅰ31 is used to open the peony seed shell, and the small peony seeds continue to move downward into the gap between the pressing wheel Ⅱ32 and the arc-shaped knife plate Ⅱ34, and the peony seed shell is opened by the rotation of the pressing wheel Ⅱ32; then the peony seeds are moved out of the arc-shaped knife plates Ⅰ33 and Ⅱ34 under the rotation of the pressing wheels Ⅰ31 and Ⅱ32, and enter the shelling component 4, and the outer shell of the peony seeds is peeled off the surface by friction; finally, the shelled peony seeds are moved to the discharge component 5 below the shelling component 4, and discharged from the device through the discharge pipe.

[0034] The peony seeds are separated by size through the screen 22, and the peony seeds of different sizes are opened respectively through the opening component 3. Under the premise of shelling peony seeds of different sizes at the same time, the damage of large peony seeds and insufficient shelling of small peony seeds caused by the different sizes of peony seeds are avoided, so that the device has a higher shelling rate.
