Chinese chestnut huller based on flexible kneading hulling with reciprocating screen

The invention discloses a Chinese chestnut huller based on flexible kneading hulling with a reciprocating screen. The Chinese chestnut huller mainly comprises a flexible kneading hulling component, a transmission mechanism, a frame, a motor, and the reciprocating screen component. The flexible kneading hulling component comprises flexible kneading plates, length-adjustable kneading arms, a feed port, fixed barriers, a lower body of a hulling chamber, and an upper body of the hulling chamber. The reciprocating screen component comprises a two-layer screen, a slide and a crank link mechanism. After the Chinese chestnuts with spiny hulls are fed into a feed hopper, the Chinese chestnuts with the spiny hulls are subject to kneading, pulling, and extruding among the rotating flexible kneading plates and the fixed barriers, and therefore the spiny hulls crack and the outer hulls are separated from the Chinese chestnuts. The separated hulls and the Chinese chestnuts drop down to the upper layer of the two-layer screen of the reciprocating screen, which is right below the hulling chamber, from the space between the fixed barriers, and the two-layer screen is driven to reciprocate on the slide by the crank link mechanism, so that the Chinese chestnuts are separated from the hulls, and then cleaned and collected.
