The walnut sheller comprises a machine frame, rollers which are driven by a power machine and arranged in parallel on the machine frame, and rollers which are concentrically sleeved and fixed outside the rollers, and a plurality of knurls are arranged on the outer circumferential surface of the rollers; Uniformly distributed rollers are arranged on the circumferential surface of the rollers, and the axial ends are closed by roller covers respectively; The upper half of the outer circumferential surface of the drum is provided with a retaining shell, and there is a distance between the retaining shell and the drum; The upper part of one end of the drum in the circumferential direction is provided with a feed inlet, and the feed inlet is provided with a hopper; The lower side of the drum cover at the other end of the drum is provided with a discharge port and a discharge hopper; There is a proper distance between the shaft end of the drum at one side of the discharge port and the cylinder head, which is beneficial to discharge.

Cucumber seed sheller. Characterized in that the melon seed sheller comprises a casing, an impeller, a feed inlet and a discharge outlet. The impeller of the melon seed sheller is installed in the shell. Drive the impeller to rotate at high speed with power. A shell is arranged at the periphery of the impeller, and various melon seeds enter the shell from the feed inlet at the upper part of the shell. The impeller blades rotating at high speed in the casing will beat the melon seeds entering the casing at high speed on the casing at the periphery of the impeller, so that the melon seeds are cracked and separated from the casing, and the melon seeds and the casing will fall to the discharge port at the lower part of the casing by their own gravity.
