Patent - Grape harvest trailer with regulated outflow

The grape harvest trailer with regulated outflow features a chassis (2) with wheels (3) and a harvest load input bin (4). The bottom (5) of the latter has a cylindrical or semi-cylindrical shape. This bottom of the bin (5) has a large diameter worm screw (6) that adapts and follows the bin bottom’s cylindrical shape. The worm screw (6) is coupled to a motor based system that allows it to rotate at a slow speed when operated; an outflow door is located at one of the bin’s extremities, where the outflow end of the screw is also located (6), helping evacuate the harvested grapes that are being stirred by the worm screw (6).
