Es sind Kolbenmaschinen zum Transport und Auftragen von Putz-Werkstoffen bekannt, die Mörtelbehälter, Rührwerk, Saug- und Verdichtungskamraer, Zylinder, Kolben und Abdichtungselemente enthalten, bei denen der Kolbenantrieb einseitig mittels eines mechanischen Untersetzungsgetriebes von einem Kurbelgetriebe erfolgt. Nachteile bei Maschinen dieser Art sind die starken Druckveränderungen, welche auf dem Transportweg entstehen, und die ihrerseits zu einem ungleichmäßigen Auftragen des Werkstoffes, sowie zu Beschädigungen der Gummileitungen führen. Der mechanische Antrieb ist schwer, kompliziert und teuer, er hält nur relativ kleine Belastungen aus und gibt keine Möglichkeit zu einem weitgehend stufenlos regelbaren Maschinenausstroß.They are piston machines for the transport and application of plaster materials known, the mortar tank, agitator, suction and compression chamber, cylinder, piston and sealing elements included, in which the piston drive on one side by means of a mechanical reduction gear of a crank gear he follows. Disadvantages with machines of this type are the strong pressure changes that occur on the transport route arise, and in turn lead to an uneven application of the material, as well as damage to the rubber lines to lead. The mechanical drive is heavy, complicated and expensive, it only holds relatively small loads and there is no possibility of a largely infinitely variable machine discharge.

Aufgabe der Erfindung ist es, eine Kolbenmaschine zum Transport und Auftragen von Putz-Werkstoffen mit zweiseitigem Betrieb zu schaffen, welche bei einer kompakten und leichteren Konstruktion eine stufenlose Werkstoffzufuhr und einen grossen Arbeitsdruck mit kleiner Antriebsleistung sichert, indem ein weitgehend stufenlos regelbarer Ausstoß ermöglicht ist.The object of the invention is to provide a piston machine for the transport and application of plaster materials with two-sided operation to create, which with a compact and lighter construction, a stepless material feed and a large Working pressure with low drive power ensures by a largely infinitely variable output is made possible.

Die Aufgabe wird durch eine Maschine zum Transport und Auftragen von Putz-Werkstoffen gelöst, bei der die Rührer symmetrisch zu der Achse der Antriebswelle angeordnet und mit der Welle mittels regelbaren Bolzens verbunden sind. Der untere Bunkerteil ist durch die Saug- und Verdichtungskammern mittels Rohrleitungen mit den Arbeitszylindern verbunden, welche koaxial und symmetrisch zum Antriebszylinder liegen,The object is achieved by a machine for transporting and applying plaster materials, in which the stirrers are arranged symmetrically to the axis of the drive shaft and are connected to the shaft by means of adjustable bolts. The lower part of the bunker is connected by the suction and compression chambers by pipelines to the working cylinders, which are coaxial and symmetrical to the drive cylinder,

der seinerseits durch einen Hydroverteiler mit dem Ausstoßregler in Verbindung steht. Durch zentrierende Zwischenkammern, die mittels Rohrleitungen mit einem gemeinsamen Behälter verbunden sind, steht der Antriebszylinder mit den Arbeitszylindern in Verbindung. An den Kammerwänden sind Induktionsendschalter angebracht. Unten in den Kammern liegen auswechselbare Bodensatzsammler.which in turn is connected to the discharge regulator through a hydraulic distributor. Through centering intermediate chambers, which are connected to a common container by means of pipes, the drive cylinder is connected to the working cylinders in connection. Induction limit switches are attached to the chamber walls. Lying down in the chambers exchangeable sediment collector.

Vorteile der Erfindung: es wird hauptsächlich eine Werkstoffzufuhr mit weitgehend stufenlos regelbarer Wirkungsweise gesichert. Die Konstruktion ist kompakt und leicht und besteht aus Elementen mit hoher Langlebigkeit, leichter Wartung und Instandhaltung. Der hydraulische Antrieb gewährleistet eine große Transportentfernung und hat einen kleinen elektrischen Anschlußwert.Advantages of the invention: there is mainly a material feed secured with largely infinitely variable mode of action. The construction is compact and lightweight and consists made of elements with a long service life, easy maintenance and servicing. The hydraulic drive ensures a long transport distance and has a small electrical connection value.

709885/0982709885/0982

tels Rohrleitungen 12 mit einem gemeinsamen Behälter 13 in Verbindung stehen, ist der Antriebszylinder 8 mit den Arbeitszylindern 7 verbunden. In den Wänden der Kammern 11 sind Induktionsendschalter 14 angebracht, unten in den Kammern 11 liegen Bodensatzsammler 15. Ein gemeinsamer Kolbenschaft 16 setzt die Arbeitskolben 17 und den Antriebskolben 18 in Gang. In den Saug- und Verdichtungskammern 6 sind die Saugventile 19 und die Verdichtungsventile 20 montiert. Durch Riementriebe werden vom Motor 21 der Presser 22 und der auf dem Sieb 24 über die Öffnung des Bunkers 1 angebrachte Rüttler 23 angetrieben. Der Motor 25 treibt mittels eines Riementriebes die Rührer 2 an. Die Saug- und Verdichtungskammern 11 sind mittels Rohrleitungen mit dem Druckkompensator 26 verbunden, an dem auch der Verdichtungsstutzen 27 angebracht ist. Mittels Leitungshahn 28 schafft die Rohrleitung 29 eine Verbindung vom Druckkompensator 26 zum Sieb 24. Der Ausstoßregler 10 verbindet die Pumpe 30 mit dem Hydroverteiler 9.means of pipes 12 with a common container 13 in Are connected, the drive cylinder 8 is with the working cylinders 7 connected. Induction limit switches 14 are fitted in the walls of the chambers 11, at the bottom of the chambers 11 there are sediment collectors 15. A common piston skirt 16 sets the working piston 17 and the drive piston 18 in motion. In the suction and compression chambers 6 are the Suction valves 19 and the compression valves 20 mounted. Belt drives are used by the motor 21 of the presser 22 and the vibrator 23 mounted on the sieve 24 via the opening of the bunker 1 is driven. The motor 25 drives by means of a Belt drive the stirrer 2. The suction and compression chambers 11 are connected to the pressure compensator by means of pipelines 26 connected to which the compression port 27 is also attached. The pipeline is created by means of the tap 28 29 a connection from the pressure compensator 26 to the sieve 24. The discharge regulator 10 connects the pump 30 to the hydraulic distributor 9.

Die Luftanalage ist bestückt mit einem Behälter, einem Sicherheitsventil, Rohrleitungen und einem Kontaktmanometer, der so eingestellt wird, daß er bei Überschreitung eines Druckes von 6 atü den Motor 31 des Hydroaggregats ausschaltet. The air system is equipped with a container, a safety valve, Pipelines and a contact manometer, which is set so that it is exceeded when one Pressure of 6 atü switches off the motor 31 of the hydraulic unit.

Die Maschine arbeitet wie folgt:The machine works as follows:

Das Hydroaggregat befördert das öl in die rechte oder linke Kammer des Antriebszylinders 8. Das Umschalten des Hydroverteilers 9 für die ölförderung in die linke oder rechte Kammer des AntriebsZylinders 8 erfolgt auf elektrischem Wege durch die Induktionsendschalter 14. Auf diese Weise wird die hin- und hergehende Bewegung des Antriebskolbens 18 bewirkt. Der rechte Arbeitszylinder 7 arbeitet folgendermaßen (analog arbeitet auch der linke):The hydraulic unit conveys the oil to the right or left Chamber of the drive cylinder 8. Switching the hydraulic distributor 9 for oil delivery to the left or right Chamber of the drive cylinder 8 takes place electrically through the induction limit switch 14. In this way causes the reciprocating movement of the drive piston 18. The right working cylinder 7 works as follows (the left one also works in the same way):

Venn sich der Kolben 17 nach links bewegt, wird in der rech ten Kammer des Arbeitszylinders 7 und in der Saug- und Verdichtungskammer 6 ein Unterdruck geschaffen. Das Ventil 19 öffnet sich und durch die Saugrohrleitung 5 v/ird vom Bunker 1 Werkstoff eingesaugt. Bei seinem Rückgang übt der Kolben einen Druck auf den Mörtel aus, das Ventil 19 schließt die Saugöffnung, das Ventil 20 wird angehoben und läßt den Mörtel zum Druckkompensator 26 durch. Von ihm wird der Mörtel zum Verdichtungsstutzen 27 befördert.Venn the piston 17 moves to the left, there is provided a negative pressure in the chamber of the working cylinder th computing 7 and in the suction and compression chamber. 6 The valve 19 opens and material is sucked in from the bunker 1 through the suction pipe 5. As it goes down, the piston exerts a pressure on the mortar, the valve 19 closes the suction opening, the valve 20 is raised and lets the mortar through to the pressure compensator 26. The mortar is conveyed from it to the compression nozzle 27.
