Walnut sheller and shelling method thereof

The invention discloses a walnut sheller and a shelling method thereof, and belongs to the technical field of walnut shelling treatment. When a walnut edge is pressed, a worker vertically inserts an auxiliary strip inwards through the top cover, a notch is formed in the middle of the walnut belly after being inserted and pressed, one end of the auxiliary strip is inserted into the notch to rotate, so that walnut shells on the two sides are unfolded outwards with the notch of the walnut belly as a fulcrum, and the walnut edge is pressed back and forth through the annular cutter set; therefore, the peach kernels fall off from the bottoms of the two groups of walnut shells; when the sliding unit moves back and forth, the adjusting sheet plate makes contact with the intervals of the multiple sets of hollow cavities to generate vibration, so that walnut shell residues left in the auxiliary box are shaken, and the shaken residues are separated from the upper end face of the adjusting sheet plate and slide downwards
