Snowplow with positive rake angle cutting blade and ice scraper

Abstract

A snowplow is presented and comprises a frame configured to be attached to a vehicle with a vehicle attachment for pushing the snowplow in a longitudinal direction, a main blade connected to a forward portion of the frame, the main blade including radius of curvature and at least one cutting blade disposed at a bottom portion of the main blade in a ground-contacting configuration disposed in a positive rake angle in substantial continuity with the radius of curvature of the main blade, the at least one cutting blade being pivotable about a pivot axis, wherein the pivot axis is located in front the main blade in an horizontal and transversal direction

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present patent application relates to an is claiming priority from U.S. Provisional Patent Application No. 62 / 753,328, entitled “SNOWPLOW AND ICE SCRAPER AND METHOD THEREOF”, filed at the United States Trademark and Patent Office on Oct. 31, 2018, the content of the '328 application is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention generally relates to snow and ice removing machines. More particularly, the present invention relates to a vehicle-mounted snowplow in which the snowplow is provided with a front pivot and optionally with an ice scraper.BACKGROUND OF THE INVENTION[0003]Snowplow assemblies are commonly mounted to a variety of vehicles during winter season in order to efficiently remove snow from paths, sideways, roadways and other areas. Actually, now in the market, there are various kinds of vehicle-mounted snowplows. Examples of conventional snowplow assemblies are provid...

AI Technical Summary

Benefits of technology

[0009]In an aspect of invention, the snowplow generally comprises a snowplow with a ground scraping portion comprising one or more pivotally mounted cutting blade. The pivots are disposed above the cutting blade and mounted on the front facing surface of the plow to improve the cutting blade pivotal motion. When the snowplow encounters obstacles, the cutting blade pivotal motion pivots the cutting blade rearwardly without significant, or any, downward motion causing the snowplow to “jump” upwardly because the cutting blade pivot position is substantially vertically aligned with the cutting blade that is substantially located at its lowest position in regard to its pivotal motion. Indeed, the location of the cutting blade pivot allow the snowplow to ride over the obstacles while reducing the upward movement effect on the snowplow when the cutting blade pivots.

[0010]In another aspect of invention, the ground-contacting cutting blade comprises a plurality of widthwise-disposed pivotally mounted cutting blade segments that are adjoined and juxtaposed to one another. When the snowplow encounters obstacles, the bottom edge of the cutting blade segments which get in contact with the obstacles are pivoting rearwardly and thereby permit the snowplow to ride over the obstacles while the other segments will remain in contact with the road surface thus limiting or preventing leaving unremoved snow on the ground where the obstacle was and where the cutting blade pivoted.

Problems solved by technology

However, this kind of snowplow is easily susceptible to jamming.

Moreover, as the snowplow blade does not have sufficient ability to remove efficiently ice that may adhere to the road, it is necessary to replace the snowplow with an ice rake and scrape the road a second time to remove the ice.

This is inefficient and a waste of time and energy.

Another drawback for existing snowplows is also evident when the snowplow encounters an obstacle as the bottom ground-contacting edge of the snowplow, more precisely the cutting blade, pivots to avoid the obstacle.
