Abstract
A snow deflection system for a snowplow includes an arcuate foil and a preferred belt. Both the foil and the belt are attached to the moldboard of the plow so that the preferred belt keeps the plowed snow close enough to the moldboard to allow the arcuate foil to direct the flow of snow and air, which blows over the top of the moldboard, down and away from the plow vehicle.
Claims5
On a snowplow vehicle for plowing snow having a moldboard with a top margin the combination comprising:
- arcuate foil means attached to said moldboard for controlling generally all of the flow of said snow above said moldboard;
- belt means permanently attached to said top margin of said moldboard and extending downwardly from said moldboard for controlling and maintaining the position of generally all of said snow in generally close proximity with said moldboard;
- said arcuate foil means and said top margin of said moldboard defining an airflow space of approximately eight to twelve inches;
- whereby said belt means keeps said snow close enough to said moldboard to allow said foil means to effectively direct said snow downwardly away from said snowplow vehicle.
On a snowplow vehicle for plowing snow having a generally arcuate moldboard with a top margin combination comprising:
- a generally arcuate foil for controlling the flow of said snow over said moldboard;
- belt means permanently attached to said top margin of said moldboard and extending downwardly from said moldboard for controlling and maintaining the position of generally all of said snow in generally close proximity with said moldboard;
- said arcuate foil being mounted above said moldboard and having a front edge and a back edge parallel to each other and parallel to the ground so that the front edge is the same distance from the ground as the back edge;
- said arcuate foil and said top margin of said moldboard defining an airflow space of approximately eight inches to twelve inches;
- said belt means also having a top edge attached to said top margin of said moldboard.
On a snowplow vehicle for plowing snow on the ground, having a moldboard with a top margin, the combination comprising:
- arcuate foil means, attached to said moldboard, for controlling the flow of said snow above said moldboard;
- belt means, attached to said top margin of said moldboard and extending downwardly from said moldboard, for controlling and maintaining the position of said snow in substantially close proximity with said moldboard;
- said arcuate foil means having a front edge and a back edge parallel to each other and parallel to the ground so that the front edge is the same distance from the ground as the back edge;
- and the back edge is positioned behind the top margin of the moldboard.
