Abstract
A mounting for a slopeboard used to grade soil on an incline is provided near the edge on the backside of a bulldozer blade on an earth moving vehicle. The mounting includes a reinforcing gusset which receives both a connection from a transverse mounting beam secured to the front of a vehicle frame and also a rearwardly and outwardly extending slopeboard support. The slopeboard is mounted about an axis extending from another gusset at the edge of the bulldozer blade rearwardly to an extremity of the slopeboard support. An actuating hinge is connected atop the slopeboard support to accommodate a pressurized fluid actuating cylinder. The slopeboard can be rotated from a vertical orientation to an outwardly extended position below grade, always behind th edge of the bulldozer blade.
Claims9
In an earth moving vehicle having a main bulldozer blade carried by a vehicle frame, the improvement comprising:
- a slopeboard disposed in cantilevered fashion to one side of said main bulldozer blade and constructed with a forwardly opening trough shaped panel reinforced from the rear by a generally triangular channel that narrows near a cantilevered end thereof,
- a transverse mounting beam secured across the front of said vehicle frame and attached to the back side of said main bulldozer blade at transversely separated rigid connections,
- a reinforcing gusset plate fastened to the back side of said main bulldozer blade at at least one of said mounting beam connections,
- a slopeboard support connected to and extending rearwardly and outwardly from said gusset plate relative to said vehicle frame,
- a horizontal mounting connection which includes a reinforcing anchor fastened to the back side of said main bulldozer blade outwardly from said reinforcing gusset plate, relative to said vehicle frame, an axle rod rigidly secured to said anchor and extending rearwardly therefrom and rigidly secured to a rearward and outward extremity of said slopeboard support, a sleeve secured to said slopeboard and disposed about said axle rod, and bushings interposed between said sleeve and said axle rod at opposite ends thereof,
- an actuating hinge connection located on said slopeboard support and inwardly relative to said vehicle frame from said horizontal mounting connection and parallel thereto, and
- a pressurized fluid actuating cylinder rotatably connected both to said actuating hinge connection and to said slopeboard at an attachment remote from said actuating hinge connection,
- whereby said slopeboard is rotatably connected to said horizontal mounting connection to thereby rotate thereabout to a selected disposition relative to said main bulldozer blade.
