Abstract

Improved device for fruit classification, of the type that has a conventional bench that supports a series of static and inclined panels, located in a parallel arrangement with each other, determining every two panels dihedral channels on which run endless bands of fruit drag, said bands being supported on driving drums, the device also having groups of rotating and tilting rollers, arranged in a tangential position with respect to the endless bands, which rollers are capable of selective separation or approach with respect to each band, thus creating said rollers calibration steps along each drag strip, characterized, essentially because each set of parallel rollers located on the different endless bands, receive displacement movement in approach or separation, with respect to the bands, through a respective connecting rod of cross command and to the upper, which for this purpose has a series of smaller rods articulated by their upper end on said control rod, meanwhile said rods are joined rigidly by their lower end on each rod of the support arms of the rollers, that the movement given to each control rod translates into the oscillation of the smaller rods, with partial rotation of each rod-axis that motivates the separation or approach of each support arm and its roller on the endless belt, achieving a selectively variable step between rollers and bands that constitutes the calibration opening of the fruits.
