Die Erfindung betrifft eine MischmaschineThe invention relates to a mixing machine
für Mörtel o. dgl., bei welcher in bekannter Weise zwischen zwei Laufrädern eine mit denFor mortar o. The like. In which in a known manner between two wheels one with the
. Laufrädern zu kuppelnde Mischtrommel gelagert ist.. Mixing drum mounted on impellers to be coupled is.
Die Trommel, welche lose auf einer Achse zwischen zwei Lauf rädern ruht, wird durch eine Zahnkranz- und Sperrklinkenkupplung in einer Drehrichtung von den Laufrädern mitgenommen. Hierdurch wird erreicht, daß die Trommel sich zeitweise schneller dreht als die Räder, wodurch eine besonders gute Durchmischung des Mörtels erzielt wird. Bei den bekannten, mit den Laufrä'dern zu kuppeln-, den Mischmaschinen ist dies nicht der Fall, da sie mit in jeder Drehrichtung der Trommel wirksamen Kupplungen ausgerüstet sind.The drum, which rests loosely on an axle between two running wheels, is through a ring gear and pawl clutch taken along by the running wheels in one direction of rotation. This means that the drum sometimes rotates faster than the wheels, which results in particularly good mixing of the mortar is achieved. With the known to be coupled with the running wheels, This is not the case with the mixing machines, as they rotate in every direction of rotation of the drum effective clutches are equipped.
Die Zeichnung zeigt die Maschine teilweise im Schnitt und teilweise in Vorderansicht.The drawing shows the machine partly in section and partly in front view.
Die Trommel α von beliebiger Form ist auf der Achse b befestigt. Letztere trägt die Räder c, c und die Deichselarme d, d. Das eine Laufrad c trägt einen Ring e mit Innenverzahnung. Die Zähne sind.schräg gestellt, so daß sie nur bei einem Drehsinn der Laufräder in Tätigkeit treten können. An der Trommel α ist eine Sperrklinke f angebracht, welche ■ für gewöhnlich durch eine Feder in Eingriff mit dem Zahnkranz e gehalten wird.The drum α of any shape is fixed on the axis b. The latter carries the wheels c, c and the drawbar arms d, d. One impeller c carries a ring e with internal teeth. The teeth are inclined so that they can only come into operation when the impellers are rotating in one direction. A pawl f is attached to the drum α, which is usually held in engagement with the ring gear e by a spring.
Die Sperrklinke läßt sich aber auch von Hand außer Eingriff mit den Zähnen des Zahnkranzes bringen.The pawl can also be manually disengaged from the teeth of the ring gear bring.
Beim Fahren der Maschine wird, wenn die Klinke f in die Zähne des Zahnkranzes e eingelegt ist, die Trommel α mitgedreht. Da nun der Schwerpunkt der Mörtelmasse niemals in die Mitte der Trommel fällt, so wird derselbe, sobald die Mörtelmasse steifer geworden ist, über die Achse b hinweggehoben. Sobald dies geschehen ist, wird der Trommel von der Mörtelmasse eine Beschleunigung erteilt. Die Trommel läuft also plötzlich schneller als die Laufräder. Der Schwerpunkt der Masse schwingt dabei etwas über seinen tiefsten Punkt hinweg und will gleich darauf wieder zurückfallen. Dem zu weiten Zurückschwingen der Masse beugt die Sperrklinke vor, da diese von dem Zahnkranz festgehalten wird. Da die Sperrklinke nicht sofort von den Zähnen des Laufrades mitgenommen wird, erfolgt zunächst ein kurzes Stillstehen der Trommel. In diesem Augenblick fällt die Mörtelmasse kräftig durcheinander. Gleich darauf nimmt dann die Trommel wieder an den Umdrehungen der Räder c teil. 'When driving the machine, when the pawl f is inserted into the teeth of the ring gear e , the drum α rotates with it. Since the center of gravity of the mortar mass never falls in the middle of the drum, it is lifted over the axis b as soon as the mortar mass has become stiffer. As soon as this is done, the drum is given an acceleration by the mortar mass. The drum suddenly runs faster than the running wheels. The center of gravity of the mass swings a little over its lowest point and immediately wants to fall back again. The pawl prevents the mass from swinging back too far, as it is held in place by the ring gear. Since the pawl is not immediately taken by the teeth of the impeller, the drum comes to a standstill for a short time. At this moment the mortar mass falls violently. Immediately thereafter, the drum then takes part again in the revolutions of the wheels c. '
Soll die Trommel entleert werden, so bringt man die Öffnung der Trommel durch Drehen der letzteren in eine bequeme Lage, wobei die Sperrklinke f die Trommel in jeder Lage von selbst festhält.If the drum is to be emptied, the opening of the drum is brought into a comfortable position by turning the latter, the pawl f holding the drum in every position by itself.
