Description

Schneefräse Die Erfindung betrifft eine Schneefräse mit mindestens einer sich um eine horizontale Achse drehendren Frästrommel, welche an ihrem Umfang mit Frässchaufeln versehen ist, die gegen die Mitte hin unter Bildung eines Bechers zusammenlaufen.Snow blower The invention relates to a snow blower with at least a milling drum rotating around a horizontal axis, which on its circumference is provided with cutting blades, which towards the middle to form a cup converge.

Solche an sich bekannte Walzenschneefräsen arbeiten nach dem Gleichlaufverfahren und schleudern den gefrästen Schnee durch einen oder mehrere Auswurfkamine oben weg.Roller snow plows of this type, known per se, work according to the synchronous process and hurl the milled snow through one or more chimneys above path.

Es kommt nun vor, daß sich in den wegzuräumenden Schneemassen infolge Rutschungen von Geröll, Steinschlag usw. etwa faustgroße Steine befinden, welche von den Frässchaufeln erfaßt, nach der Frästrommelmittve hin befördert werden und in die Becher gelangen. Da sie über diese hinausragen, deformieren und beschädigen sie die Becherpartie und das Bodenmesser der Fräse, sobald die Steine an diesem anstehen, was Betriebsunterbrechungen und teuere Reparaturarbeiten verursacht.It now happens that in the snow masses to be cleared as a result Landslides from rubble, falling rocks, etc. are about fist-sized stones, which detected by the milling blades, transported to the milling drum center and get into the cups. Since they protrude beyond this, they deform and damage the cup section and the bottom knife of the milling machine as soon as the stones are attached to it pending, causing business interruptions and expensive repairs.

Durch die Erfindung sollen diese Nachteile behoben werden. Dies wird dadurch erreicht, daß die Becherrückwand schwenkbar gelagert und in ihrer Betriebslage durch einen Abscherbolzen festgehalten ist.The invention is intended to remedy these disadvantages. this will achieved in that the cup rear wall is pivotably mounted and in its operating position is held in place by a shear bolt.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigt Fig. 1 eine Ansicht einer Frästrommel von vorn, Fig. 2 eine teilweise Seitenansicht der Frästrommel gemäß Fig. 1, Fig. 3 einen Schnitt durch den Becher nach der Linie A -A in Fig. 1, Fig. 4 eine Ansicht des Bechers in Richtung des Pfeiles B in Fig. 3. An exemplary embodiment of the subject matter of the invention is shown in the drawing. 1 shows a view of a milling drum from the front, FIG. 2 shows a partial side view of the milling drum according to FIG. 1, FIG. 3 shows a section through the cup along the line A-A in FIG. 1, FIG. 4 shows a view of the Cup in the direction of arrow B in FIG. 3.

Die Schneefräse weist eine linke und eine rechte Frästrommel 1 auf, von denen in der Zeichnung der Einfachheit halber nur die eine gezeigt ist. Diese Frästrommeln drehen sich um eine gemeinsame, horizontale Achse, welche durch die Lagerbüchse 13 hindurchgeht. Am Trommelumfang sind eine Mehrzahl, beispielsweise fünf, gegen die Trommelmitte hinlaufende Fräsmesser 2 vorhanden, die in der Mitte je in einen Becher 3 ausmünden. Hinter den Frästrommeln befindet sich das Schneeführ-ungsbleoh 14, das sich den Konturen der Frästrommel anschmitgt. In Bodennähe ist an diesem Schneeführungsblech ein Bodenmesser 15 befestigt, und auf der Oberseite mündet das Schneeführungsblech auf einem Teil seiner Breite in einen Auswurfkanal 16 aus. Die Frästrommeln sind so gelagert, daß der Antrieb von der Mitte aus erfolgt, wobei die Drehrichtung in Fig. 2 durch Pfeil C angegeben ist. Zwischen dem Antriebsmotor und den Frästrommeln sind in der Zeichnung nicht dargestellte Rutschkupplungen eingebaut. Die Rückwand 4 der Becher ist je mit einem Bolzen 5 verbunden, welcher sich in stationären Lagerbüchsen 6, die an den Fräsmessem 2 angeschweißt sind, drehen kann, so daß die Rückwand 4 verschwenkbar ist und nach hinten geklappt werden kann. In ihrer normalen Betriebslage wird die Rückwand durch einen vom Bolzen 5 distanzierten Abscherbolzen 11 festgehalten, welcher beispielsweise aus Messing bestehen kann und beidseitig die Fräsmesser 2 durchstößt. Die Sicherung des Abscherbolzens gegen Herausfallen geschieht durch einen etwa in der Mitte angebrachten Federstift 12.The snow blower has a left and a right milling drum 1 , only one of which is shown in the drawing for the sake of simplicity. These milling drums rotate about a common, horizontal axis which passes through the bearing bush 13 . On the drum circumference there are a plurality, for example five, of milling cutters 2 running towards the drum center, each of which opens into a cup 3 in the center. Behind the milling drums is the snow guiding bleoh 14, which adapts to the contours of the milling drum. A floor knife 15 is attached to this snow guide plate close to the ground, and on the upper side the snow guide plate opens out over part of its width into an ejection channel 16. The milling drums are mounted in such a way that they are driven from the center, the direction of rotation being indicated by arrow C in FIG. Slipping clutches (not shown in the drawing) are installed between the drive motor and the milling drums. The rear wall 4 of the cup is each connected to a bolt 5 which can rotate in stationary bearing bushes 6 welded to the milling cutters 2 so that the rear wall 4 can be pivoted and folded back. In its normal operating position, the rear wall is held in place by a shear bolt 11 which is spaced apart from the bolt 5 and which can be made of brass, for example, and which pierces the milling cutter 2 on both sides. The shear bolt is secured against falling out by a spring pin 12 attached approximately in the middle.

Die Funktionsweise der Fräse ist folgende: Die auf der Frontseite eines Motorfahrzeuges befestigten Frästrommeln 1 drehen sich in Richtung des Pfeiles C (Fig. 2) und werden durch das Motorfahrzeug gegen den wegzuräumenden Schnee in Richtung des Pfeiles D bewegt. Wenn sich nun durch Ein-klemmen eines Steines z. B. zwischen Bodenmesser 15 und Becherrückwand 4 eine Überbeanspruchung des Abscherbolzens 11 ergibt, wird dieser durchgeschert, so daß keine bleibenden Deformationen am Bodenmesser 15 oder am Becher entstehen können. Durch Einsetzen eines neuen Abscherbolzens 11 ist die Schneefräse, deshalb sofort wieder gebrauchsfähig, ohne daß kostspielige Reparaturen und Unterbrechungen der Räumungsarbeit notwendig sind.The milling machine works as follows: The milling drums 1 attached to the front of a motor vehicle rotate in the direction of arrow C (FIG. 2) and are moved in the direction of arrow D by the motor vehicle against the snow to be cleared away. If now by jamming a stone z. B. between bottom knife 15 and cup rear wall 4 results in overstressing the shear pin 11 , this is sheared, so that no permanent deformations on the bottom knife 15 or on the cup can occur. By inserting a new shear bolt 11 , the snow thrower is therefore immediately ready for use again, without expensive repairs and interruptions in the clearing work are necessary.
