| 摘要 |
In one, aspect of the present invention, a plow protection device is disclosed. Such a device may, for example, protect a plow against substantial damage from impact with an obstruction such as a utility cover. In various embodiments of the present invention, the plow protection device multiplies velocity, distance, and kinetic energy at the point of impact between the plow and the obstruction to lift the plow's cutting edge up and away from the obstruction and the road or other plowing surface. By actively lifting the cutting edge over the impacted obstruction, embodiments of the present invention thereby limit the duration and severity of impact and minimize the resulting stresses. In another aspect of the present invention, a wear protector is provided to protect one or more components of the present invention and/or plow from wear due to friction with the plowing surface.
