Abstract

Improvements in olives harvesting machines, of the type equipped with an engine that drives a fan whose suction, produced through the corresponding hoses or pipes, cause the olives to be collected, by suction and storage thereof, after their passage by the cleaning mechanism, in the compartment or storage box, characterized in that the cleaning mechanism consists of a cylindrical screen housed in a hermetic chamber in which it is mounted with the ability to turn around its axis, presenting one of the bases of the screen a peripheral toothed crown for its operation through the corresponding pinion and a central circular opening through which passes the fan suction duct, which starts from the interior of the screen, also having the opposite base a central opening to through which the aspiration pipe of the articulated configuration olive drains into the sieve a, forming inside the chamber that encloses to said screen a longitudinal hopper that opens into a second longitudinal chamber provided with an internal rotating impeller, whose blades arranged longitudinally tightly fit against the internal surface of said chamber and conduct the fruit and received particles to a lower longitudinal outlet opening, and in that the screen has a peripheral helix internally and has three consecutive sections of different passage openings in its wall, the section next to the entrance of passage openings of a size that allows only the pass of particles inferior to the fruit, the intermediate section of openings that allow the passage of the fruit, and the last section of openings that allow the passage of particles superior to the fruit, being on the other hand the lower chamber divided transversely in three sections facing each one of the sections mentioned of the screen, of which the first and the third they open to the outside and the second to a pneumatic transport duct that takes the fruit to the storage box.
