Detailed Description

The invention is further described with reference to the following figures and specific examples.

Referring to fig. 1, the small-sized breeding huller comprises a hulling roller 2, a concave plate sieve 4, a feeding device 3, a U-shaped guide rail 5 and a guide rod 11.

Referring to fig. 2-7, the present embodiment is directed mainly to the component 2 in fig. 1, namely a peanut shelling drum with flexible beating plates with variable diameters, the shelling drum 2 has a shelling rotating component 201, the shelling rotating component 201 includes a shelling disk 201b and several beating plate U-shaped supports 201a fixed radially at equal angles around the shelling disk, an L-shaped support plate 203 is arranged in the beating plate U-shaped supports 201a, and the length of one end of the L-shaped support plate 203, which is located in the beating plate U-shaped support 201 aU-shaped groove width, is smaller than the U-shaped groove width; the L-shaped supporting plate 203 and the U-shaped support 201a clamp a rubber flexible beating plate 202; an adjusting bolt 204 penetrates through the bottom surface of the U-shaped support 201a to abut against one end of the L-shaped support plate 203, and the extending length of the rubber flexible beating plate 202 can be adjusted; the fastening bolt 205 is screwed with a screw hole on one side surface of the U-shaped support 201a, and the rubber flexible beating plate 202 is pressed and fixed by pressing the L-shaped support plate 203.
