<p>The invention relates to an elevator with rigid screw and angular adjustment for vertically conveying granular materials or seeds, consisting of a rigid structure () on which there is hingedly mounted, by a hinge (), a swinging support () on which there are fixed a driving electromotor () and an elevating housing () wherein a rigid screw () acts to convey the granular material stored within a hopper (), wherefrom it flows freely into a cavity () of the elevating housing (), by means of a front nozzle (), a flexible connection () and a back nozzle (), the flow of granular material taken over by the rigid screw () driven by the driving electromotor () by means of a transmission belt () being discharged through a discharge unit () provided with a discharging nozzle (), on each of the said rigid structure () and swinging support () there being provided a circular sector-shaped running track () with slots () wherethrough stiffening screws () pass to permit the change of the positioning angle of the swinging support () and, thus, of the elevating housing () as against the rigid structure (), allowing the elevating height to be set at the desired level.</p> |
