Abstract
An earth mover comprising at least one wheeled axle; a supported frame movable by the axle, said frame further including means for pushing up soil, comprising an elongate scraper blade with a ground-facing sharp longitudinal edge being substantially right-angled to the forward direction of travel of the apparatus. The apparatus is characterized by a cylindrical rotor provided at an interspace from, and in operative position above, the scraper blade, and substantially parallel thereto. It is also characterized by means for rotating the rotor in a direction from the longitudinal edge towards the upper portion of the scraper blade; and by bars mounted on the rotor. The distance from the turning circle circumference of the bars to the scraper blade decreases in the rotation direction of the rotor.
Claims5
An earth mover comprising
- (A) at least one wheeled axle;
- (B) a supported frame movable by said axle, said frame further including means for pushing up earth, comprising an elongate scraper blade with a ground-facing sharp longitudinal edge being substantially right angled to the forward direction of travel of said frame,
- characterized by
- (C) a cylindrical rotor spaced from, and in operative positive position above, said scraper blade and substantially parallel thereto;
- (D) means for rotating said rotor in a direction from said longitudinal edge towards the upper portion of said scraper blade;
- (E) flat bars fixedly mounted on said rotor, with the distance from the turning circle circumference of said bars to said scraper blade decreasing in the rotation direction of said rotor and reaching a minimum closely adjacent the highest part of said scraper blade.
