Apparatus for selecting horticultural products

An apparatus for selecting horticultural products, comprising an intake section for horticultural products, which leads to at least one passage lane defined by a pair of mutually close stems supported rotatably by a respective support and movement assembly and interposed longitudinally between said intake section and a discharge section, between said at least one pair of stems, kept inclined downward from said intake section to said discharge section, there is a longitudinal slot that can be crossed exclusively by debris and horticultural products having dimensions that are smaller than the width of said slot, said assembly comprising a drive unit which meshes with a first end portion of each one of said stems that is proximate to said intake section, and respective elements for the free support of a second end portion of each one of said stems that is proximate to said discharge section, wherein each one of said elements for free support is constituted by an arm that is anchored in an upper region to said assembly and has, in a lower region, a seat for rotatable accommodation of a respective said second end portion of a corresponding said stem;

• each one of said arms being inclined, with respect to the vertical, in order to remain spaced from the respective portion of said passage lane, which corresponds substantially to the region of space that is interposed between the corresponding lateral surfaces of said second end portions of said stems;
• said apparatus further comprising means for adjusting the position of at least one of said stems, in order to vary selectively the shape and/or width of the respective said slot said means for adjusting the position of at least one of said stems comprising a first unit for actuating the transverse movement of a slider that is integral with at least one said arm for supporting said second end of a corresponding said stem, for a consequent variation of the shape and/or width of the respective said slot.
