Sloper apparatus

A mobile sloping apparatus comprising:

• a prime mover;
• an arm assembly having first and second ends, a first end being operatively connected to the prime mover such that said arm assembly can undergo rotational movement about a vertical axis in relation to said prime mover;
• a sloper assembly secured to said second end of said arm assembly such that said sloper assembly can undergo rotational movement about an axis parallel to a longitudinal axis of said prime mover as well as longitudinal movement along an axis lying at an angle to said prime mover longitudinal axis, said sloper assembly comprising:
• a trunion pivotally mounted to said arm assembly second end, and
• a planar sloper blade extending substantially parallel in relation to a bottom face of said trunion, said sloper blade having a first end at which it is secured to said trunion and a second end adapted to contact a ground surface, said blade second end being located closer to said prime mover than said blade first end, said sloper blade being substantially angled such that said blade second end is located at an obtuse angle in relation to said blade first end.

A boom grading apparatus comprising:

• a prime mover;
• a sloping blade adapted for scraping a ground surface, wherein said sloping blade is substantially angled such that a first end of said blade is located at an obtuse angle in relation to a blade second end;
• a trunion to which one end of said sloping blade is secured;
• a boom assembly including a first boom arm movably interconnected to said prime mover and a second boom arm pivotally interconnected at a first end with said first arm and, at a second end, with said trunion;
• a hydraulic actuator mounted on said second boom arm, and having longitudinally separated extensible and contractible positions, said hydraulic actuator being operatively connected at a first end with said second boom arm;
• and
• a linkage assembly pivotally secured to said trunion and said second boom arm, said linkage assembly comprising:
• a first link having a first end pivotally coupled to said second boom arm, an elbow region pivotally coupled to a second end of said hydraulic actuator, and a second end, and
• a second link having a first end pivotally coupled to said trunion, and a second end pivotally connected to said first link second end, said linkage assembly converting a longitudinal motion of said hydraulic actuator into rotational motion of said trunion about said second boom arm.

A mobile sloping apparatus comprising:

• a prime mover;
• an arm assembly operatively connected at a first end to said prime mover;
• and,
• a planar sloper blade operatively connected, at a first end, to a second end of said arm assembly, wherein said sloper blade extends in a plane generally normal to a longitudinal axis of said arm assembly and wherein said sloper blade includes a second end, which is adapted to contact an associated ground surface, wherein said sloper blade second end is located at an obtuse angle in relation to said sloper blade first end.
