Grain spreader for use in agricultural field, has grain distribution chamber communicating with grain distribution units and air flow inlet channel so that grains are brought by gravity towards chamber for being evacuated towards units

摘要

The spreader has a grain transporting unit (2) interposed between a projecting outlet of a grain tank (1) and a grain distribution chamber (10), which is projected by the unit (2). The chamber communicates with grain distribution units (3) and an air flow inlet channel (13) so that the grains are evacuated by gravity outside the tank towards the unit (2) and are brought by gravity through the unit (2) towards the chamber (10) for being evacuated towards the units (3) by positive driving of the units (3) under effect of air flow generated by a wind tunnel (4).
