Referring to fig. 4-5, the screen sheet with the trapezoidal cross section is sequentially extruded and embedded into the corresponding wedge-shaped bayonets at the two sides, so that the welding procedure can be omitted, the installation is convenient, welding slag and craters formed by welding are avoided, the damage to peanuts in the operation process is reduced, and the operation quality is improved. Two inverted L-shaped hangers are arranged at the front and the rear of the concave sieve, and can be stably hung on a support frame of the shelling equipment and conveniently replaced. Because the vertical embedding bayonet socket of sieve piece ensures that the sieve piece adopts less thickness still to possess high intensity, non-deformable when the operation, and the screening area of concave plate sieve has also effectively been guaranteed to the sieve piece of less thickness, improves the operating efficiency. The preset wedge-shaped bayonet ensures that each sieve sheet is accurately positioned, ensures the consistency of the gaps of the sieve sheets and further improves the peanut shelling operation quality. Not only simple structure articulates reliably, and it is convenient to change, also is favorable to improving shelling operation quality and productivity ratio.

In this embodiment, referring to fig. 2-3, the feeding device 3 comprises a hopper 304 covering the sieve body 4 and enclosing the hulling drum 2 together with the sieve body 4, the hopper having a material inlet above.
