Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to aid in a better comprehension of the invention's features, according to a preferred practical embodiment example thereof, it is provided, as integral part of said description, a number of drawings in which, for illustrative and non-limiting purposes, the following has been represented:

[0028] FIG. 1 is a perspective view of the shelling mechanism for nuts, for a preferred embodiment of the invention.

[0029] FIG. 2 is a perspective view of a seesaw of the cracking and shelling mechanism for nuts, for a preferred embodiment of the invention.

[0030] FIG. 3 is a side view of the seesaw of the cracking and shelling mechanism for nuts, for a preferred embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0031] In view of the drawings provided, it can be seen how in a preferred embodiment of the invention, the cracking and shelling mechanism for nuts, for shelling machines, hereby proposed comprises a plurality of first elongated parallel blocks (1) with a first end (1.1) fastened to alternate movement means in both senses along the longitudinal axis thereof and a plurality of second elongated parallel blocks (2) parallel to the first blocks and arranged in an alternate and adjacent way to the first blocks.

[0032] Each of these first and second blocks exhibit a first and second ends (1.1, 1.2, 2.1, 2.2) and two sides (8), in such a way that between the sides (8) of each first and second blocks (1, 2) a plurality of vertical cracking through holes (7) is defined.

[0033] As shown in FIG. 1, the movement means in each first block (1) comprises a seesaw element (3) which is connected to at least a pair of blocks formed by said first block (1) and to an adjacent second block (2), in such a way that the second blocks (2) exhibit an alternate movement in both senses along their longitudinal axis and in opposite sense to the movement od said adjacent first block (1).

[0034] In this preferred embodiment of the invention, as shown in FIG. 1, the seesaw is connected to two pairs of blocks formed by two first and two second blocks (1, 2) adjacent to each other. In other embodiments it can be connected to a different number of blocks or even to a unique first block (1) and to a second block (2) adjacent thereto.

[0035] This seesaw element (3), as it can be observed in FIGS. 2 and 3, comprises a fixed central rotation shaft (4), placed at the same height than the plurality of first and second blocks (1, 2), a first rod (5) connected by a first end (5.1) to the central shaft (4) and by a second end (5.2) to the first end (1.1) of the two first blocks (1) by first connection means or connectors, and a second rod (6) connected by a first end (6.1) to the central shaft (4), diametrically opposed to the first rod (5), and by a second end (6.2) to the first end (2.1) of the second blocks (2), by second connection means or connectors.

[0036] Both, first and second rods (5, 6) exhibit the same length, such that the displacement of each first and second blocks (1, 2) is the same.

[0037] In this preferred first embodiment, the first connection means to a first block are formed by a first arm (9), with a first end (9.1) fastened to the first end (1.1) of the first two blocks (1), by a first rotation shaft (11). Since in this case the seesaw is connected to the first two blocks, it exhibits two arms (9), each of them connected to each one of the first arms.

[0038] Likewise, the second connection means comprise a second arm (10) with a first end (10.1) fastened to the first end (2.1) of the second blocks (2) and with a second end (10.2) connected to the second end (6.2) of the second rod (6), by a second rotation shaft (12). Since in this case the seesaw is connected to two second blocks, it exhibits two second arms (10), each connected to one of said second arms.

[0039] The described embodiment constitutes an example of the present invention, therefore specific details, terms and phrases used in the present specification do not have to be construed as limiting, but have to be interpreted only as a representative basis that provides a comprehensible description, as well as the sufficient information so as to the skilled person in the matter be able perform the present invention.
