Benefits of technology

This patent describes a plow blade assembly with articulating blades that can move in different directions. The blades have angled chamfers that work together to allow for smooth movement and better conformance to the surface being plowed. This design also improves the assembly's ability to remove obstacles, reduce damage to the road surface, and minimize the impact on the driver's experience. Additionally, the small size of the blade segments makes installation and replacement easier, and the ability to conform to the road surface is improved.

Problems solved by technology

Steel blades have the advantage of being relatively inexpensive, but also the disadvantage of wearing out rapidly since the scraping operation can be a very abrasive operation.
Replacement of the steel blade is, of course, time consuming and represents downtime for the equipment.

Embodiment Construction

[0018]Referring to FIGS. 1 and 2, there is illustrated a plow blade assembly 10 in accordance with an aspect of the invention. The plow blade assembly 10 may be mounted on or used in association with a vehicle (not shown) for plowing or grading a surface, such as, for example, a road surface or earth strata.

[0019]Still referring to FIGS. 1 and 2, the plow blade assembly 10 includes a moldboard adapter plate 12, a cover plate 14, and a flexible or articulating blade 16 mounted between the moldboard adapter plate 12 and the cover plate 14. As best illustrated in FIG. 1, the moldboard adapter plate 12 may be a continuous member. The cover plate 14 may include multiple cover plate members 14a corresponding to multiple articulating blade segments 16a of the articulating blade 16. Thus, it will be appreciated that the components of the plow blade assembly 10, i.e., the moldboard adapter plate 12, the cover plate 14, and the articulating blade 16, may be provided in various configurations ...

Abstract

A plow blade assembly includes a moldboard adapter plate, a cover plate, and an articulating blade mounted between the moldboard adapter plate and the cover plate. The articulating blade includes a bushing assembly mounted therein, wherein the bushing assembly includes an elastomeric bushing and a non-elastomeric spacer non-centrally located in the elastomeric bushing. In one aspect, the non-elastomeric spacer is positioned adjacent a top edge of the elastomeric bushing.

Description

BACKGROUND OF THE INVENTION[0001]The invention pertains generally to a plow blade assembly for use in conjunction with snow plows and like vehicles, wherein the plow blade assembly travels over the surface of a substrate (e.g., the surface of a roadway) to remove snow and ice, as well as other debris and material, and provide for improved impact and performance properties.[0002]Snow plows are well known and carry a relatively-long moldboard which extends generally laterally (or across) of the substrate surface being worked by the blade. It is conventional practice to mount a snow plow blade, e.g., a cutting blade, on the lower edge of such moldboard with the blade, in turn, extending downwardly below the lower edge of the moldboard. The blade has a lower leading edge that forms the working surface of the blade. The vehicle carrying the blade then moves over the surface of the substrate in a direction generally perpendicular to the length of the moldboard. The blade then contacts or ...
