1. A cracking-shelling mechanism for nuts with a hard or soft shell, for nut shelling machines, comprising:
a plurality of first longitudinal blocks parallel to one another which are configured to reciprocate in both directions according to a longitudinal axis thereof, and
a plurality of second longitudinal blocks parallel to the first longitudinal blocks and arranged in an alternating and adjacent manner with respect to same, wherein all the blocks have first and second ends, respective lower and upper bases, and two sides, and wherein between the sides of each first and second block there is formed a plurality of tapered vertical through holes between the upper and lower bases of the blocks,
facing sides between each first and second block comprise a plurality of first and second notches, respectively, complementary to one another and in a staggered arrangement, such that each first notch is associated with at least a second notch and forms the through hole with each second notch associated with it,
said first and second notches have, for each hole, first and second vertexes demarcating a contour thereof, arranged such that the first vertex is farther away from the longitudinal axis of the corresponding block than the second vertex, and each first and second vertex associated with hole is aligned forming a specific angle with respect to said longitudinal axis, and wherein in a standby position of the first block, each first and second vertex of each first notch is arranged so as to coincide with second and first vertexes, respectively, of a second notch, configuring a closed curved shape.
