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
- 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.
- 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 impacts any material (e.g., snow and ice and other materials) on the surface of the substrate so as to dislodge and remove the same.
- In the past, such blades have been made of steel. 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. Once worn out, one must replace the steel blade to avoid damage to the moldboard. Replacement of the steel blade is, of course, time consuming and represents downtime for the equipment. Thus, various techniques, such as impregnation and hardfacing of the blade cutting edge with carbide particles. For example, cemented carbide inserts can be attached into or onto the blade edge in an attempt to prolong the life of the steel blade.
- While known blades appear to operate reasonably well under the operating conditions for which they were designed, most blades seem to embody one or more shortcomings in terms of complexity, performance, durability, reliability, and/or cost effectiveness. Thus, there remains a need to provide an improved blade structure, e.g., snow plow blade that exhibits more acceptable performance properties.
- In accordance with an aspect of the invention, 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.
- In accordance with another aspect of the invention, an articulating blade for a plow blade assembly includes a blade segment having a bottom surface for contacting a surface and a bushing assembly mounted in the blade segment. The bushing assembly includes an elastomeric bushing and a non-elastomeric spacer non-centrally located in the elastomeric bushing.
- In accordance with yet another aspect of the invention, an articulating blade for a plow blade assembly includes a first blade segment having a bottom surface for contacting a surface, the first blade segment further having a first angled chamfer formed on an end thereof. The articulating blade also includes a second blade segment adjacent the first blade segment also having a bottom surface for contacting the surface, wherein the second blade segment further has a second angled chamfer formed on an end thereof. The first angled chamfer and the second angled chamfer are structured and arranged for cooperating with each other to provide for variable degrees of movement of the first blade segment and the second blade segment relative to one another.
- Advantageously, it will be appreciated that the plow blade assembly of the invention provides: for better conformance to a substrate, e.g., road surface to provide for better cleaning and/or removal action; for improved movability to avoid obstructions, reduce shock, and vibration and reduce damage to a road surface; and smaller blade sections for ease of installation and replacement, as well as improved ability to conform to the road surface.
- These and other aspects of the present invention will be more fully understood following a review of this specification and drawings.

FIGS. 1 and 2 , there is illustrated aplow blade assembly 10 in accordance with an aspect of the invention. Theplow 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. - Still referring to
FIGS. 1 and 2 , theplow blade assembly 10 includes amoldboard adapter plate 12, acover plate 14, and a flexible or articulatingblade 16 mounted between themoldboard adapter plate 12 and thecover plate 14. As best illustrated inFIG. 1 , themoldboard adapter plate 12 may be a continuous member. Thecover plate 14 may include multiplecover plate members 14 a corresponding to multiple articulatingblade segments 16 a of the articulatingblade 16. Thus, it will be appreciated that the components of theplow blade assembly 10, i.e., themoldboard adapter plate 12, thecover plate 14, and the articulatingblade 16, may be provided in various configurations and arrangements as desired and necessary for particular uses and applications of theplow blade assembly 10. - Referring to
FIGS. 2-5 , each articulatingblade segment 16 a includes one or morebushing assemblies 20 mounted or formed in theblade segment 16 a. Thebushing assembly 20 includes anelastomeric bushing 22 and anon-elastomeric spacer 24 non-centrally located in theelastomeric bushing 22. Thenon-elastomeric spacer 24 may be formed of, for example, steel. - The
non-elastomeric spacer 24 defines anopening 26 that is generally axially aligned with anaperture 28 formed in thecover plate members 14 a of thecover plate 14 and anotheraperture 30 formed in themoldboard adapter plate 12 such that abolt 32 may pass therethrough and cooperate with anut 34 for assembling theplow blade assembly 10. It will be appreciated that other means for assembling, connecting, or attaching the various components of theplow blade assembly 10 may be provided in accordance with aspects of the invention. - As described herein and illustrated in the figures, the
non-elastomeric spacer 24 is non-centrally located in theelastomeric bushing 22. In one aspect, thenon-elastomeric spacer 24 is offset from the center of theelastomeric bushing 22. In another aspect, thenon-elastomeric spacer 24 is positioned adjacent atop edge 36 of theelastomeric bushing 22. In another aspect, atop portion 38 of thenon-elastomeric spacer 24 is generally contiguous with thetop edge 36 of theelastomeric bushing 22. Advantageously, by positioning thenon-elastomeric spacer 24 within theelastomeric bushing 22, as described and illustrated herein, enhanced and improved flexibility of the articulatingblade 16 can be achieved. This, in turn, provides for improved performance and durability of the articulatingblade 16 that contacts a surface which results in overall improved performance of theplow blade assembly 10. - In another aspect of the invention, the
elastomeric bushing 22 may be generally square. In addition, thenon-elastomeric spacer 24 may also be generally square. However, it will be appreciated that theelastomeric bushing 22 may be provided in other shapes and configurations and that thenon-elastomeric spacer 24 also may be provided in other shapes and configurations. Also, theelastomeric bushing 22 may have a different shape than the shape of thenon-elastomeric spacer 24. - In operation of the
plow blade assembly 10, the articulatingblade 16 is structured and arranged for movement relative to themoldboard adapter plate 12 and thecover plate 14 as theplow blade assembly 10, and more particularly, the articulatingblade 16, contacts a surface for providing a plowing or grading operation. In one aspect, the relative movement of the articulatingblade 16 relative to themoldboard adapter plate 12 and thecover plate 14 is provided by thenon-elastomeric spacer 24 having a thickness T1 that is greater than a thickness T2 of theelastomeric bushing 22. (See, for example,FIG. 4 .) Thus, when the articulatingblade 16 is arranged between themoldboard adapter plate 12 and thecover plate 14, as described herein, thenon-elastomeric spacer 24 with the greater thickness T1 contacts themoldboard adapter plate 12 on one side and thecover plate 14 on the opposing side so as to allow for eachblade segment 16 a of the articulatingblade 16 to move relative to themoldboard adapter plate 12 and thecover plate 14. This relative movement of the articulatingblade 16, and more particularly, the relative movement of the articulatingblade segments 16 a, allows for the articulatingblade 16 to remain in more direct contact with the surface that is being plowed or graded. It will be appreciated that thebolt 32 assembly also contributes to the relative movement of the articulatingblade segments 16 a. - Referring to
FIG. 7 , a bottom edge orbottom surface 40 of the articulatingblade 16 includes a plurality ofhard inserts 42 for contacting a surface. Thehard inserts 42 may be made of, for example, tungsten carbide, for providing increased wear and performance of theplow blade assembly 10. - Referring to
FIGS. 5-8 , another aspect of the invention provides for increasing maneuverability of theblade segments 16 a that form the articulatingblade 16. More particularly, angled chamfers 44 are formed on opposing ends of each of the articulatingblade segments 16 a. Thus, when theblade segments 16 a are positioned adjacent to one another, one angledchamfer 44 from afirst blade segment 16 a cooperates with another angled chamfer on asecond blade segment 16 a so as to provide for variable degrees of movement between the twoblade segments 16 a. (See, for example,FIG. 8 .) It will be appreciated that the blade segments may move more freely in an up-and-down direction and side-to-side direction relative to one another during use of theplow blade assembly 10. The angled chamfers 44 also advantageously operate to reduce the amount of material that may accumulate between ends ofadjacent blade segments 16 a during operation. - Whereas particular aspects of this invention have been described above for purposes of illustration, it will be evident to those skilled in the art that numerous variations of the details of the present invention may be made without departing from the invention as defined in the appended claims.
