Vane type ridge construction device of paddy field ridge construction machine

A vane type ridge construction device of a paddy field ridge construction machine is a piece of agricultural machinery. A ridge top surface forming cone or cylinder assembly is fixedly installed on a driven disk of a clutch with a clutch operating lever. A driving screw is fixedly installed on a driving disk of the clutch. A plurality of ridge side surface forming vanes are evenly hinged to an end part on one side of the ridge top surface forming cone or cylinder assembly along the circumferential direction. The adjacent ridge side surface forming vanes are arranged to overlap with each other and are connected by vane applying control pins. A ring-shaped pedestal sleeves the driving screw, is fixed in the axial and radial direction and can rotate in the circumferential direction. An ear plate nut is screwed onto the driving screw. Two ends of an outer support plate are hinged to the ridge side surface forming vanes and the ear plate nut respectively. Two ends of an inner support plate are hinged to the outer support plate and the ring-shaped pedestal respectively. The ridge construction machine can satisfy operation needs of different ridge sizes and shapes, has a novel and reasonable structure, is simple and convenient for adjustment, is highly adaptable, and constructs ridges with good quality.
