In addition, the material passing channel 12 generally has a material outlet 122 and a material inlet 121, and the lotus seedpod enters from the material inlet 121, is processed by the threshing mechanism 2 in the accommodating chamber 11, and then flows out from the material outlet 122 to the screening mechanism 3. The specific arrangement of the material passing channel 12, the material inlet 121 and the material outlet 122 is not limited in the present invention. Preferably, as shown in fig. 1, the material passing channel 12 extends vertically, the material inlet 121 is disposed above the material passing channel 12, and the material outlet 122 is disposed below the accommodating cavity 11.
