Abstract

A snowblower with a propeller drum seated on a free support axle that is disposed horizontally and perpendicular to the driving direction. The support axle is operated by a drive which is situated centrally within the drum. The snowblower also serves a lateral snowblowing function by the connection of a snowplow in place of the usual second drum. The side of the snowplow adjacent to the propeller drum is fixed rigidly to the housing. The back side of the snowplow is connected to a bushing which can be placed on the support axle normally provided for the removed propeller drum.

Description

Die Erfindung betrifft eine Schneefräse mit zwei Frästrommein, die auf freien, horizontal und quer zur Fahrtrichtung liegenden Tragachsen eines zentralen innerhalb der Frästrommel angeordneten Getriebes sitzen.The invention relates to a snow blower with two milling drums, which are seated on free, horizontally and transversely to the direction of travel supporting axes of a central gear arranged within the milling drum.

Derartige Schneefräsen, wie beispielsweise in der deutschen Patentschrift 2147001 beschrieben, sind seit langem bewährt. Ihre Räumbreite liegt üblicherweise in einem Bereich zwischen 2 und 3 m, wenn beide Trommelhälften im Einsatz sind. Jeder Trommelhälfte ist meistens ein gesonderter Auswurfkamin zugeordnet, welcher den von der jeweiligen Trommelhälfte aufgenommenen Schnee entweder frei auswirft oder auf die Laderfläche eines LKW fördert.Such snow blowers, as described for example in German patent 2147001, have been tried and tested for a long time. Their clearing width is usually in a range between 2 and 3 m when both drum halves are in use. Each drum half is usually assigned a separate ejection chimney, which either ejects the snow picked up by the respective drum half freely or conveys it to the loading area of a truck.

Für den Einsatz im Stadtgebiet, insbesondere zum Räumen oder Verladen von Randwällen wurden sogenannte Seitenschneefräsen entwickelt. Deren Räumbreite wird etwa zur Hälfte von einer Frästrommel, im übrigen von einem Zuführungs-Schneepfluggebildet. Dessen Schar ist schräg angeordnet, so dass ihre Aussenkante in Räumrichtung vor ihrer der Frästrommel benachbarten Innenkante liegt. Der Zuführungs-Schneepflug fördert dabei seitlich von der Frästrommel liegenden Schnee vor die Frästrommel, die ihrerseits. den auf diese Weise zugeführten und den im Bereich des Randwalls vor ihr liegenden Schnee aufnimmt.So-called side snow blowers have been developed for use in urban areas, in particular for clearing or loading ramparts. About half of their clearing width is formed by a milling drum, the rest by a feed snow plow. Its share is arranged obliquely, so that its outer edge lies in the broaching direction in front of its inner edge adjacent to the milling drum. The feed snow plow conveys snow lying to the side of the milling drum in front of the milling drum, which in turn. the snow fed in this way and the snow lying in front of it in the area of the edge wall.

Des öfteren ist es aber erwünscht, eine Schneefräse sowohl im Stadtgebiet zum Randwallentfernen als auchzur Flächenräumung, z.B. von tiefverschneiten Fahrbahnen oder Parkplätzen einzusetzen. Die beschriebene Seitenschneefräse ist für die Flächenräumung ungeeignet, da sie wegen des Zuführungs-Schneepfluges bei grösseren Schneehöhen und in hartem Schnee stecken bleibt. Die bekannte Schneefräse mit zwei unmittelbar nebeneinander angeordneten Frästrommeirr hat wiederum für die Randwallbeseitigung Nachteile, da die neben dem Randwall liegende Frästrommel ungenutzt mitdreht. Dies bedeutet nicht nur Verschwendung von Energie, sondern auch die Gefahr, dass der Auswurfkamin der ungenutzten Frästrommel verstopft, da bei geringer Förderleistung die Auswurfgeschwindigkeit des Schnees entsprechend niedrig ist. Bei verstopftem Auswurfkamin muss die Räumarbeit wiederholt zur Beseitigung der Verstopfung unterbrochen werden. Die ungenutzt mitdrehende Frästrommel bedeutet zudem beim Einsatz innerhalb von Ortschaften eine Gefahr für Passanten.Often, however, it is desirable to use a snow blower both in the city area to remove edge walls and to clear areas, e.g. of snow-covered lanes or parking lots. The side snow blower described is unsuitable for clearing areas, because due to the supply snow plow it gets stuck in larger snow heights and in hard snow. The known snow blower with two milling drums arranged directly next to one another in turn has disadvantages for removing the edge wall, since the milling drum lying next to the edge wall also rotates unused. This means not only wasting energy, but also the risk that the discharge chute of the unused milling drum becomes blocked, since the snow discharge speed is correspondingly low with a low conveying capacity. If the chute is blocked, the clearing work must be interrupted repeatedly to remove the blockage. The unused rotating drum also poses a danger to passers-by when used in urban areas.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine universell einsetzbare, d.h. sowohl zum Randwallräumen als auch zum Flächenräumen geeignete Schneefräse zu schaffen.In contrast, the present invention has for its object to provide a universally applicable, i.e. to create snow blowers suitable for clearing marginal walls as well as for clearing areas.

Diese Aufgabe wird erfindungsgemäss an einer Schneefräse der eingangs genannten Art dadurch gelöst, dass anstelle einer der beiden Frästrommeln eine Pflugschar anschliessbar ist, derart, dass deren der verbleibenden Frästrommel benachbarte Seite an einem gehäusefesten Teil befestigt und deren Rückseite über eine Stütze mit einer auf die freie Tragachse des Getriebes aufsteckbaren Muffe verbunden ist.This object is achieved according to the invention on a snow blower of the type mentioned at the outset in that a ploughshare can be connected instead of one of the two milling drums, in such a way that its side adjacent to the remaining milling drum is fastened to a part fixed to the housing and the back of which is attached to the free part via a support Carrying axis of the gearbox is connected to the sleeve.

Eine derartige Schneefräse bietet für den Käufer die Möglichkeit des einfachen Umbaus einer Schneefräse mit zwei Frästrommeln in eine Seitenschneefräse mit nur einer Frästrommel und einem Schneepflug anstelle der zweiten Frästrommel. Dabei wird beim Einsatz im Rechtsverkehr, in Räumrichtung gesehen, die linke, also die Fahrbahninnere Frästrommel durch den Schneepflug ersetzt. Dies geschieht im Rahmen des Erfindungsvorschlags verblüffend einfach dadurch, dass die Frästrommel von der Tragachse des Getriebes abgezogen und die Muffe für die Schneepflugbefestigung über diese gesteckt wird. Der Pflugwinkel kann dadurch verändert werden, dass man die Länge der Stütze variiert. Dies kann stufenweise oder kontinuierlich, manuell oder motorisch bzw. hydraulisch erfolgen.Such a snow blower offers the buyer the possibility of simply converting a snow blower with two milling drums into a side snow blower with only one milling drum and a snow plow instead of the second milling drum. When used in right-hand traffic, when viewed in the clearing direction, the left, i.e. the inside of the milling drum, is replaced by the snow plow. In the context of the proposal for the invention, this is done amazingly simply by pulling the milling drum off the carrying axis of the gear unit and inserting the sleeve for the snow plow attachment over it. The plow angle can be changed by varying the length of the support. This can be done in stages or continuously, manually or by motor or hydraulically.

Durch symmetrische Ausbildung des Scharkörpers der Pflugschar bezüglich einer horizontalen Achse besteht die Möglichkeit, die Pflugschar wahlweise an die Stelle der linken (Rechtsverkehr) oder rechten (Linksverkehr) Frästrommel anzubringen. Voraussetzung ist dabei lediglich, dass Befestigungselemente für die lösbare Befestigung der Räumleiste sowohl an der oberen als auch an der unteren Kante des Scharkörpers vorgesehen sind.By symmetrically forming the share of the ploughshare with respect to a horizontal axis, it is possible to attach the ploughshare either to the left (right-hand traffic) or right (left-hand traffic) milling drum. The only requirement is that fastening elements for the releasable fastening of the clearing bar are provided both on the upper and on the lower edge of the share body.

Höhe und Länge der Pflugschar können dem Durchmesser und der Länge einer Frästrammelhälfte angepasst sein.The height and length of the ploughshare can be adapted to the diameter and the length of one half of the milling cutter.

Bei einer solchen Ausführung wird die durch die abgezogenen Trommelhälfte gebildete Lücke des Fräsengehäuses wieder geschlossen.In such an embodiment, the gap of the milling cutter housing formed by the removed drum half is closed again.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung, erläutert.An exemplary embodiment of the invention is explained below with reference to the drawing.

Die Schneefräse gem. Fig. 1 besitzt zwei Frästrommeln 1, 2, von denen die in der Zeichnung strichpunktiert angegebene rechte Frästrommel 2 abgenommen ist. Die beiden Frästrommeln 1, 2 schliessen zur Mitte hin dicht an einen Ringsteg 3 an. Der Ringsteg 3 sowie ein im Inneren der Frästrommeln untergebrachtes Getriebe 4 mit beidseitigen Tragachsen 5 sind gehäusefest angeordnet. Der Antrieb (Fig. 3) erfolgt über eine fahrzeugseitig angetriebene Gelenkwelle 21, welche über ein Kettenradgetriebe 22 auf das Getriebe 4 für die beiden Frästrommeln 1, 2 treibt. Das Getriebe 4, z.B. in Art eines Winkelgetriebes, liegt in der Mitte zwischen den beiden hohlen Frästrommeln. Auf dem Frästrommelgehäuse 6, welches an der oberen Vorderkante bewegliche Klappen 7 zur Verhinderung des Schneeauswurfs nach vorn aufweist, sitzen zwei Auswurfkamine 8, 9, von denen jeder einer Frästrommel zugeordnet ist. Längs der Unterkante des Frästrommelgehäuses 6 erstreckt sich eine auswechselbare Verschleissschiene 10. Abnehmbare Schneemesser 23 an den oberen Seitenkanten des Frästrommelgehäuses 6 dienen zum Abscheren überhängender Schneewände.The snow blower acc. Fig. 1 has two milling drums 1, 2, of which the right milling drum 2 shown in dash-dotted lines in the drawing has been removed. The two milling drums 1, 2 close to a ring web 3 towards the center. The ring web 3 and a gear 4 housed in the interior of the milling drums with supporting axes 5 on both sides are fixed to the housing. The drive (FIG. 3) takes place via a drive shaft 21 which is driven on the vehicle side and which drives the gear 4 for the two milling drums 1, 2 via a chain wheel gear 22. The gear 4, for example in the manner of an angular gear, lies in the middle between the two hollow milling drums. Two ejection chimneys 8, 9, each of which is assigned to a milling drum, are located on the milling drum housing 6, which has flaps 7 movable on the upper front edge to prevent snow being ejected to the front. Along the Un The edge of the milling drum housing 6 extends through an exchangeable wear rail 10. Removable snow blades 23 on the upper side edges of the milling drum housing 6 serve to shear off overhanging snow walls.

Eine in Fig. 2 dargestellte Pflugschar 11 mit Räumleiste 12 besitzt an ihrer linken vertikalen Kante Ösen 13, 14, welche dem gelenkigen Anschluss an entsprechenden Doppelösen 15, 16 des Ringstegs 3 dienen. Die Bolzen zur Sicherung dieser gelenkigen Verbindung sind nicht dargestellt. Auf der Rückseite der Pflugschar 11 ist, wie in Fig. 3 ersichtlich, eine Stütze 17 bei 18 gelenkig angeschlossen. Die Stütze 17 ist mit ihrem gegenüberliegenden Ende bei 19 ebenfalls gelenkig an eine Muffe 20 angeschlossen. Die Muffe 20 besitzt eine Bohrung zur Aufnahme der Tragachse 5.A ploughshare 11 shown in FIG. 2 with a clearing bar 12 has eyelets 13, 14 on its left vertical edge, which are used for the articulated connection to corresponding double eyelets 15, 16 of the ring web 3. The bolts for securing this articulated connection are not shown. On the back of the ploughshare 11, as shown in FIG. 3, a support 17 is articulated at 18. The support 17 is also pivotally connected to a sleeve 20 at its opposite end at 19. The sleeve 20 has a bore for receiving the supporting axis 5.

Die Muffe 20 ist bis zu einem getriebseitigen Anschlag 21 des Getriebegehäuses 25 über die Tragachse 5 geschoben, so dass letztere vollständig in der Bohrung der Muffe 20 aufgenommen ist.The sleeve 20 is pushed up to a stop 21 on the transmission side of the transmission housing 25 over the supporting axis 5, so that the latter is completely received in the bore of the sleeve 20.

Die in der Zeichnung dargestellte Pflugschar 11 ist bezüglich einer in Fig. 2 angedeuteten horizontalen Achse a unsymmetrisch ausgebildet. Bei symmetrischer Ausbildung des Scharkörpers 24 der Pflugschar 11 besteht die Möglichkeit der Anbringung der Pflugschar wahlweise anstelle der links dargestellten Frästrommel 1 oder der rechts dargestellten Frästrommel 2. In diesem Fall wäre lediglich die Räumleiste 12 an der gegenüberliegenden Kante 26 zu befestigen, welche bei symmetrischer Ausbildung des Scharkörpers 24 den gestrichelt gezeichneten Verlauf haben könnte. Die Anbringung entsprechender Befestigungselemente längs beider waagrechter Kanten der Pflugschar bereitet keine Schwierigkeiten.The ploughshare 11 shown in the drawing is asymmetrical with respect to a horizontal axis a indicated in FIG. 2. In the case of a symmetrical formation of the share body 24 of the ploughshare 11, there is the possibility of attaching the ploughshare either instead of the milling drum 1 shown on the left or the milling drum 2 shown on the right. In this case, only the clearing bar 12 would have to be attached to the opposite edge 26, which with symmetrical training of the share body 24 could have the dashed line. The attachment of appropriate fasteners along both horizontal edges of the ploughshare is not difficult.

Gemäss Fig. 3 erkennt man auf der Rückseite des Fräsengehäuses 6 die beidseitigen Laufräder 28 mit deren Höhenverstellung dienenden Handrädern 29, ferner zwei Anlenkstützen 30 zur Befestigung des Fräsengehäuses 6 an der Frontseite eines nicht dargestellten Trägerfahrzeugs. Abweisringe 31 an den Aussenseiten des Fräsengehäuses 6 schützen die Frästrommein 1, 2 vor Beschädigung.According to FIG. 3, on the back of the cutter housing 6, the two-sided impellers 28 with their height adjustment serving handwheels 29, as well as two articulation supports 30 for fastening the cutter housing 6 on the front of a carrier vehicle, not shown, can be seen. Deflection rings 31 on the outer sides of the milling housing 6 protect the milling streams 1, 2 from damage.
