Definitions
- the invention relates to a scraper blade for the plow blade of a snow plow, which is provided at the top with a steel mounting neck for attachment to the plow blade.
- a problem with using these scrapers is that the lateral end portion of the scraper bar, i. H. the area that clears the roadside of ice and snow, wears laterally. In particular, upon impact of the scraper on obstacles such. As curbs, this is damaged and thus reduced in their Räumbreite.
- the ploughshare is already equipped with separate edge deflectors.
- the object of the invention is therefore to provide a curb for a scraper, which is separately replaceable and yet enters into a solid connection to the scraper.
- the invention proposes that at least at one side edge of the scraper a Randsteinabweiser is arranged, wherein the side edge of the scraper is inserted into a recess of the curb deflector.
- the curb deflector is additionally reinforced by the scraper blade in it and a form-locking connection between the scraper bar and curb deflector manufactured, which has large support surfaces which extend transversely to the direction of the forces acting on the curb during broaching forces.
- a tearing of the curb deflector of the scraper is almost impossible.
- the curb deflector has a polygonal or rounded contour in cross-section and is preferably cylindrical. This shape of the curb deflector allows extensive protection of the Räumangnkante in all directions. Likewise, there are no additional edges that could catch on the obstacle and thus be damaged.
- the invention provides that the Randsteinabweiser has in cross-section two pitch circle elements, which are so assembled to form a Retro Vietnameseneuveelement that the side edge of the Räumang between the pitch circle elements is arranged.
- This two-part version of the curb deflector improves the positive connection of the Räumangnkante with the pitch circle elements of the Curb Repellent.
- a particularly advantageous embodiment of the invention provides that the first part circle element in cross-section substantially describes a 3 ⁇ 4-circle cutout and the side edge of the Räummann from the front and from the side includes, and that the second part circle element in cross-section substantially describes a 1 ⁇ 4-circle cutout and rests against the scraper from behind.
- This design protects the most heavily loaded portions of the curb deflector with a one-piece design of the 3 ⁇ 4 part circle element, while the 1 ⁇ 4 pitch element, which can be positively connected with the 3 ⁇ 4 part circle element, serves to stabilize and secure the entire curb deflector. Due to the positive connection of the scraper with the subcircuit elements a shifting of the individual parts is additionally prevented from each other.
- the Randsteinabweiser is screwed to the scraper, with a screw so through the scraper and the Randsteinabweiser can be passed that a screw head in the direction of travel of the snowplow in the curb stone deflector is retractable and a nut in the direction of travel opposite direction behind the ploughshare and the curb deflector can be screwed.
- the curb deflector consists essentially of a steel body, with which a plurality of hard metal pieces is materially connected, in particular soldered, is.
- a trained curb scraper is due to the integrated carbide pieces very resistant to abrasive wear.

Description
Die Erfindung betrifft eine Räumleiste für den Räumschild eines Schneepfluges, die oben mit einem stählernen Befestigungshals zur Befestigung am Räumschild versehen ist.The invention relates to a scraper blade for the plow blade of a snow plow, which is provided at the top with a steel mounting neck for attachment to the plow blade.
Räumleisten dieser Art sind in verschiedenen Ausführungsformen aus dem Stand der Technik bekannt.Scrapers of this type are known in various embodiments from the prior art.
Ein Problem beim Einsatz dieser Räumleisten besteht darin, dass der seitliche Endbereich der Räumleiste, d. h. derjenige Bereich, der den Straßenrand von Eis und Schnee frei räumt, seitlich verschleißt. Insbesondere beim Aufprall der Räumleiste auf Hindernisse, wie z. B. Bordsteine, wird diese beschädigt und damit in ihrer Räumbreite reduziert.A problem with using these scrapers is that the lateral end portion of the scraper bar, i. H. the area that clears the roadside of ice and snow, wears laterally. In particular, upon impact of the scraper on obstacles such. As curbs, this is damaged and thus reduced in their Räumbreite.
Zur Vermeidung solcher Beschädigungen wird die Pflugschar bereits mit separaten Randabweisern ausgestattet.To avoid such damage, the ploughshare is already equipped with separate edge deflectors.
Da die Arbeitshöhe der Pflugschar jedoch höher liegt als die der Räumleiste und der Randsteinabweiser der Pflugschar in der Regel nicht nach unten über die Pflugschar vorsteht, können durch diese Randsteinabweiser Kollisionen mit dem Bordstein nicht verhindert werden, wenn der Bordstein niedriger ist als die Räumleiste.However, since the working height of the ploughshare is higher than that of the scraper and the curb of the ploughshare usually not projecting down over the ploughshare collisions with the curb can not be prevented by these curbs when the curb is lower than the scraper.
Im Stand der Technik finden sich des Weiteren auch Lösungen, welche Randsteinabweiser an der Räumleiste eines Schneepfluges vorsehen.
Schwierigkeiten ergeben sich bei dieser Lösung durch eine von Klemmschrauben gehaltene Welle, welche den rotierenden Randsteinabweiser trägt. Die außen liegenden Klemmschrauben liegen im Angriffsbereich des zu räumenden Schnees und können sich dadurch lockern. Im schlimmsten Fall können Einzelteile der Vorrichtung auf die Straße fallen und andere Verkehrsteilnehmer gefährden.Difficulties arise in this solution by a shaft held by clamping screws, which carries the rotating curb deflector. The outer clamping screws lie in the attack area of the snow to be cleared and can thereby loosen. In the worst case, parts of the device may fall on the road and endanger other road users.
Um diese Problematik zu vermeiden, existieren ebenfalls Lösungen, welche eine einstückige Ausgestaltung von Räumleiste und Randsteinabweiser vorsehen. In der Gebrauchsmusterschrift
Diese einstückige Ausgestaltung von Räumleiste und Randsteinabweiser verhindert jedoch einen separaten Austausch von Räumleiste oder Randsteinabweiser. Hierdurch muss bei Verschleiß oder Beschädigung eines der beiden Teile jeweils die komplette Vorrichtung getauscht werden, was höhere Kosten als notwendig verursacht.However, this one-piece design of scraper and curb deflector prevents a separate replacement of scraper or curb repellent. As a result, in case of wear or damage to one of the two parts in each case the entire device must be replaced, which causes higher costs than necessary.
Aufgabe der Erfindung ist es daher, einen Randsteinabweiser für eine Räumleiste zu schaffen, welcher separat austauschbar ist und dennoch eine feste Verbindung zu der Räumleiste eingeht.The object of the invention is therefore to provide a curb for a scraper, which is separately replaceable and yet enters into a solid connection to the scraper.
Zur Lösung dieser Aufgabe schlägt die Erfindung vor, dass zumindest an einem Seitenrand der Räumleiste ein Randsteinabweiser angeordnet ist, wobei der Seitenrand der Räumleiste in eine Aussparung des Randsteinabweisers einfügbar ist. Indem der Seitenrand der Räumleiste in die Aussparung des Randsteinabweisers eingefügt wird, wird zusätzlich der Randsteinabweiser durch die in ihm befindliche Räumleiste verstärkt und eine Formschlussverbindung zwischen Räumleiste und Randsteinabweiser hergestellt, die große Stützflächen aufweist, die quer zur Richtung der bei der Räumarbeit auf den Randsteinabweiser einwirkenden Kräfte verlaufen. Somit ist ein Abreißen des Randsteinabweisers von der Räumleiste annähernd ausgeschlossen.To solve this problem, the invention proposes that at least at one side edge of the scraper a Randsteinabweiser is arranged, wherein the side edge of the scraper is inserted into a recess of the curb deflector. By inserting the side edge of the scraper bar in the recess of the curb deflector, the curb deflector is additionally reinforced by the scraper blade in it and a form-locking connection between the scraper bar and curb deflector manufactured, which has large support surfaces which extend transversely to the direction of the forces acting on the curb during broaching forces. Thus, a tearing of the curb deflector of the scraper is almost impossible.
Besonders vorteilhaft im Sinne der Erfindung ist es, wenn der Randsteinabweiser im Querschnitt eine polygonale oder abgerundete Kontur aufweist und vorzugsweise zylinderförmig ausgebildet ist. Diese Formgebung des Randsteinabweisers erlaubt einen großflächigen Schutz der Räumleistenkante in alle Stoßrichtungen. Ebenso entstehen keine zusätzlichen Kanten, welche sich mit dem Hindernis verhaken und dadurch Schaden nehmen könnten.Particularly advantageous in the context of the invention, it is when the curb deflector has a polygonal or rounded contour in cross-section and is preferably cylindrical. This shape of the curb deflector allows extensive protection of the Räumleistenkante in all directions. Likewise, there are no additional edges that could catch on the obstacle and thus be damaged.
Die Erfindung sieht vor, dass der Randsteinabweiser im Querschnitt zwei Teilkreiselemente aufweist, welche so zu einem Gesamtkreiselement zusammenfügbar sind, dass der Seitenrand der Räumleiste zwischen den Teilkreiselementen angeordnet ist. Diese zweiteilige Ausführung des Randsteinabweisers verbessert den formschlüssigen Verbund der Räumleistenkante mit den Teilkreiselementen des Randsteinabweisers.The invention provides that the Randsteinabweiser has in cross-section two pitch circle elements, which are so assembled to form a Gesamtkreiselement that the side edge of the Räumleiste between the pitch circle elements is arranged. This two-part version of the curb deflector improves the positive connection of the Räumleistenkante with the pitch circle elements of the Curb Repellent.
Eine besonders vorteilhafte Ausgestaltung der Erfindung sieht vor, dass das erste Teilkreiselement im Querschnitt im Wesentlichen einen ¾-Kreisausschnitt beschreibt und den Seitenrand der Räumleiste von vorne und von der Seite her umfasst, und dass das zweite Teilkreiselement im Querschnitt im Wesentlichen einen ¼-Kreisausschnitt beschreibt und von hinten an der Räumleiste anliegt. Durch diese Ausgestaltung werden die am stärksten belasteten Teilbereiche des Randsteinabweisers durch eine einstückige Ausführung des ¾-Teilkreiselements geschützt, während das mit dem ¾-Teilkreiselement formschlüssig verbindbare ¼-Teilkreiselement zur Stabilisierung und Befestigung des gesamten Randsteinabweisers dient. Durch die formschlüssige Verbindung der Räumleiste mit den Teilkreiselementen wird zusätzlich ein Verschieben der einzelnen Teile zueinander verhindert.A particularly advantageous embodiment of the invention provides that the first part circle element in cross-section substantially describes a ¾-circle cutout and the side edge of the Räumleiste from the front and from the side includes, and that the second part circle element in cross-section substantially describes a ¼-circle cutout and rests against the scraper from behind. This design protects the most heavily loaded portions of the curb deflector with a one-piece design of the ¾ part circle element, while the ¼ pitch element, which can be positively connected with the ¾ part circle element, serves to stabilize and secure the entire curb deflector. Due to the positive connection of the scraper with the subcircuit elements a shifting of the individual parts is additionally prevented from each other.
Zweckmäßig ist der Randsteinabweiser mit der Räumleiste verschraubbar, wobei eine Schraubverbindung so durch die Räumleiste und den Randsteinabweiser hindurchführbar ist, dass ein Schraubenkopf in Fahrtrichtung des Schneepflugs in dem Randsteinabweiser versenkbar ist und eine Mutter in der Fahrtrichtung entgegengesetzter Richtung hinter dem Räumschild und dem Randsteinabweiser verschraubbar ist. Dadurch, dass der Schraubenkopf in dem Randsteinabweiser versenkt wird, minimiert sich die Angriffsfläche zwischen Schnee und Schraubenkopf, so dass eine Lockerung der Schraubverbindung verhindert wird. Da die zugehörige Mutter in entgegengesetzter Richtung, d. h. gegen die Fahrtrichtung des Schneepflugs, hinter dem Räumschild mit der Schraube verschraubt wird, kommt diese mit dem Schnee nicht in Berührung. Somit lässt sich ein Lösen der Schraubverbindung und damit ein Abfallen des Randsteinabweisers von der Räumleiste verhindern.Suitably, the Randsteinabweiser is screwed to the scraper, with a screw so through the scraper and the Randsteinabweiser can be passed that a screw head in the direction of travel of the snowplow in the curb stone deflector is retractable and a nut in the direction of travel opposite direction behind the ploughshare and the curb deflector can be screwed. The fact that the screw head is sunk in the curb stone, the attack surface between the snow and the screw head is minimized, so that a loosening of the screw is prevented. Since the associated nut is screwed in the opposite direction, ie against the direction of travel of the snowplow, behind the plow blade with the screw, this comes with the snow not in contact. Thus, a loosening of the screw and thus prevent falling of the curb deflector of the scraper.
Zweckmäßig besteht der Randsteinabweiser im Wesentlichen aus einem Stahlkörper, mit dem eine Vielzahl von Hartmetallstücken stoffschlüssig verbunden, insbesondere verlötet, ist. Ein derart ausgebildeter Randsteinabweiser ist aufgrund der eingebundenen Hartmetallstücke sehr resistent gegen abrasiven Verschleiß. Insbesondere empfiehlt sich als Hartmetall Wolframcarbid, das für ähnliche Aufgaben bereits angewendet wird.Suitably, the curb deflector consists essentially of a steel body, with which a plurality of hard metal pieces is materially connected, in particular soldered, is. Such a trained curb scraper is due to the integrated carbide pieces very resistant to abrasive wear. In particular, tungsten carbide, which is already used for similar tasks, is recommended as hard metal.
Ebenso kann der Randsteinabweiser aus einem verschleißfesten, gehärteten Stahl oder Hartguss bestehen. Hartguss bezeichnet dabei ein metastabiles Gusseisen mit hohem Carbidanteil.Likewise, the curb repellent can consist of a wear-resistant, hardened steel or chilled cast iron. Chilled cast iron refers to a metastable cast iron with a high carbide content.

Die Erfindung funktioniert so, dass die beiden Teilkreiselemente 3, 4 mit der Räumleiste 1 so verschraubt werden, dass eine formschlüssige Anordnung entsteht. Dabei wird das ¾- Teilkreiselement 3 von vorne und von der Seite um den Seitenrand der Räumleiste 1 gelegt und das ¼- Teilkreiselement 4 von hinten, gegen die Fahrtrichtung des Schneepfluges, an die Räumleiste 1 angelegt. Eine Schraube 5 wird nun so durch das ¾- Teilkreiselement 3, die Räumleiste 1 sowie das ¼- Teilkreiselement 4 geschoben, dass der Schraubenkopf 5 in dem ¾- Teilkreiselement 3 des Randsteinabweisers 2 versenkt ist. Auf der Rückseite der Räumleiste 1 wird eine Mutter 6 mit der Schraube 5 so verschraubt, dass das ¼- Teilkreiselement 4 des Randsteinabweisers 2 fest an der Räumleiste 1 anliegt.The invention works so that the two
Bei dem Einsatz der erfindungsgemäßen Räumleiste 1 mit Randsteinabweiser 2 wird die Räumkante der Räumleiste 1 durch den Randsteinabweiser 2 vor einem Aufprall auf z. B. Bordsteine geschützt. Bei einem Aufprall kommt das Hindernis lediglich mit dem ¾- Teilkreiselement 3 des Randsteinabweisers 2 in Kontakt. Der verdrängte Schnee greift ebenfalls vorrangig an dem ¾- Teilkreiselement 3 an, so dass die hinter der Räumleiste 1 befindliche Mutter 6 nicht gelöst werden kann.When using the scraper 1 according to the invention with
