Claim:
1. A device for harvesting long agricultural products, comprising: a frame having a main axis of extension (A) which, during use, is kept transversal to an advancing axis (D) of the device; pick-up means designed to harvest agricultural products from the ground; unloading means located operatively downstream of the pick-up means, forming a supporting surface (B) for the agricultural products harvested and mobile along said main axis of extension (A) for releasing the agricultural products to a side of said device; said unloading means comprising a conveyor belt extending along said axis of extension (A) between a first end and a second end, opposite to the first end, and laterally delimited by a first longitudinal edge, associated with the pick-up means, and by a second longitudinal edge opposite to the first edge, wherein an external surface of said conveyor belt forms said supporting surface (B) mobile from the first end to the second end; at least a cleaning unit positioned above said supporting surface (B) of the unloading means and having: a circular wheel comprising a peripheral annular surface extending annularly with a series of apexes and grooves along its circumference and rotatable about its own axis of rotation (C), joining means designed to connect said wheel to said harvesting device so that said axis of rotation (C) is transversal to said axis of extension (A) and positioned at a predetermined height and its peripheral annular surface faces the supporting surface (B) to form, between the peripheral annular surface of the wheel and the supporting surface (B), an agricultural product drag section.
