Abstract
To provide a scraper and a process for removal of soil or similar materials of a land usually irregular. The scrapers of the state of the art include some problems, such as change of scraper when the land includes several types of material to be removed, for example, dry soils combined with muddy ones, to facilitate the thrust of the scraper to release from stuck the machine and provide a scraper with a construction that allows movements of land in a more controlled due to that the cutting blade does not vary its angle of attack when you move the tilting box. The scraper of the present invention comprises both an unloading system by a tilting box as an unloading system through an ejector.

A scraper with dual downloading mechanism that includes a front, a central and a rear part, wherein the front part joins the middle section by means of a parallelogram mechanism (701) and the intermediate section joins the rear part through another parallelogram mechanism (702).
A device of articulated element (800) wherein it comprises:
- a first body (801);
- a second body or centerpiece (802);
- and
- a third body (803) of hook;
- Where the first body joins articulable to the center piece (802), which in turn joins articulately the third body (803) of hook, the connection between the first body and the central part is performed by means of a cylindrical arrow (804) that includes a first portion of a larger diameter (804A), a rod (804B), a keyway section (804C), a neck (804D) and finally the end (804E). The arrow (804) is introduced into the borehole past (802A), supported on bushings (806). Perpendicular to this borehole (802A), the borehole (802B) is made, which also includes two bushings (808A), which will be used to accommodate the short bolts (808), secured to the body (801) by means of a threaded screw plate (808b) or some similar element, correspondingly, to the borehole (801E). The short bolt (808) is inserted through the borehole (801C) for coupling with bushings (808A), this borehole (801C) is located on the plate (801A).
