Cracking and shelling mechanism for nuts

A cracking and shelling mechanism for nuts, for shelling machines, that comprises a plurality of first elongated parallel blocks with a first end fastened to alternate movement means in both senses along the longitudinal axis thereof and a plurality of second elongated parallel blocks parallel to the first blocks and arranged in an alternate and adjacent way to the first blocks, wherein all blocks exhibit a first and second ends and two sides, in such a way that between the sides of each first and second blocks a plurality of vertical cracking through holes is defined;

• the movement means of each first block comprises a seesaw element which is connected to at least one pair of blocks formed by said first block and an adjacent second block, such that the second blocks exhibit an alternate movement in both senses along the longitudinal axis thereof, and in opposite sense to the movement of said first adjacent block, wherein said seesaw element comprises a fixed central rotation shaft, placed at the same height as the plurality of first and second blocks, a first rod connected by a first end to the central shaft and connected by a second end also to the first end of the first block by a first connector, and a second rod connected by a first end to the central shaft, diametrically opposed to the first rod, and connected by a second end also to the first end of the second blocks, by a second connector, wherein the first and second rods exhibit the same length.
