MOULDBOARD MOUNTING OF SNOW PLOUGH Russian patent published in 1998 - IPC

FIELD: road maintenance machinery and equipment. SUBSTANCE: this primarily relates to universal road maintenance machinery and is adapted for quick and simple transformation into machines for moving and spreading loose materials. For example this mouldboard mounting is used in plough-type snow cleaners with adjustable angles of mouldboard setting which protects machine from dynamic loads when encountering invisible obstacles. Mounting setup has frame which is pivotally secured and suspended on hydraulic cylinder 3. Frame is provided with pushing beams. Seated on these beams through holes 5 in mouldboard 4 is mouldboard itself. Mouldboard can be turned in vertical planes by means of hydraulic cylinder 8 which is installed between rear side of mouldboard and frame. Turning of mouldboard in horizontal plane is ensured by changing position of mouldboard relative to holes in frame. These holes receive pins for fixing mouldboard in position. EFFECT: higher efficiency. 2 dwg
