Cracking-Shelling Mechanism With Variable Excentric Adjustment For Shelled Fruits

Abstract

The present invention refers to a cracking-shelling mechanism with variable eccentric adjustment for shelled fruits, that comprises a plurality of longitudinal blocks parallel among them, consisting of a couple of first elongated bars with recesses on its internal sides and, adjacent to said first elongated bars, at least one second elongated bar, which exhibits recesses on its internal sides, forming holes when the first and second elongated bars are confrontedly arranged. Each couple of first elongated bars is connected by means of a lever, in its turn connected to a connecting rod, to an eccentric rotation shaft. The lever is connected to a fastening means at a support point and the support means comprises displacement means that change its position with respect of the fastening means, in such a way that the first elongated bars run is adjusted, jointly, with respect of the second elongated bar.

DETAILED DESCRIPTION OF THE INVENTION

[0039] The drawings show preferred embodiments of the invention.

[0040] In FIG. 1C, it can be observed that the cracking-shelling mechanism of the invention comprises a plurality of first elongated bars 4 parallel among them and a plurality of second elongated bars 5 parallel to the first elongated bars and alternately arranged and adjacent thereof, forming blocks.

[0041] In FIG. 1C, it can be seen that the first and second elongated bars 4, 5 exhibit sides with semi-circular adjacent recesses and between the sides of each first and second elongated bars 4, 5, a plurality of vertical passing holes 8 is formed.

[0042] In FIG. 1A and in FIG. 2, it is observed that each couple of first mobile bars 4 are connected at a first end, by means of a lever 6 in its turn coupled to a first connecting rod 1, to an eccentric rotation shaft 10. Each couple of first elongated bars 4 exhibits al alternate movement in both senses along the longitudinal axis of said first elongated bars 4.

[0043] In FIG. 1A and in FIG. 2, it is observed that the lever 6 is connected to a fastening means 7 at a support point 3. The fastening means 7 comprises of displacement means that move the position of the support point 3 in relation with the fastening means 7 and an actuator 2 which moves the position of the support point 3. The movement of the position of the support point 3 with respect of the fastening means 7 jointly adjusts the run of the first mobile elongated bars 4 with respect of the second fixed elongated bars 5.

[0044] In FIG. 2, it can be seen a guiding spindle 9, in such a way that the fastening means 7 is vertically displaced along the guiding spindle 9.

[0045] In FIG. 3 three different positions of the displaceable support point 3 are shown. The distance D is the same in all three and due to the three positions of the support point 3 shown in FIG. 3, according to the lever principle, distances C, B and A keep the following order: C>B>A.

[0046] In FIG. 4 it is observed a couple of second mobile elongated bars 5, connected to a seesaw 11 that comprises a central rotation shaft and a fixed connecting rod 12, in turn connected at a first end to the central shaft and at a second end to the second end of the second elongated bars 5 and a third connecting rod 13 connected also in turn at a first end to the central shaft, in opposite fashion to the second connecting rod 12, and at a second end to the second end of the first elongated bars 4, in such a way that the second elongated bars 5 exhibit an alternate displacement in both senses along the longitudinal axis thereof and in opposite sense to the displacement of the first elongated bars 4. The arrows show the movement sense of the first and second elongated bars 4, 5 in a given moment of the operation of the cracking-shelling mechanism of the invention.
