Abstract

The concrete spreading or spraying machine is for transfer and distribution of concrete, mortar or other materials, and has one or more additions and for binder media which are used in solid or liquid states. The binder or additive materials, are transported and worked by means of a conveyor spiral which acts simultaneously as a mixing device, transportation device and non-return type safety system allowing the additive materials or binders to be added to the concrete mix by means of forces occuring within the transport system.

Description

Bezeichnung: Betonförder- und Verspritzmaschine Beschreibung: Es sind maschinen bekannt,die Betone aus Kies,Sand,auch Leichtzuschlägen,mit Zement als Bindemittel,aber auch Mörtel u.s.w. im Naß- oder Trockenverfahren in einem Arbeitsgang Fördern,Einbringen und verdichten.Designation: Concrete conveying and spraying machine Description: There are machines known to make concretes from gravel, sand, also lightweight aggregates, with cement as Binders, but also mortar etc. in a wet or dry process in one operation Conveying, bringing in and compressing.

Vorherrschend wird das Gemisch im Trockenverfahren mittels ventilgesteuerter Schleusenkammern,Zellenradschleuse oder geeigneter Pumpen in eine- Druckluftstrom eingeführt und durch eine Schlauch-oder Rohrleitung zur Einbaustelle gefördert.The mixture is predominantly in the dry process by means of valve-controlled Lock chambers, rotary valve or suitable pumps in a compressed air stream introduced and conveyed through a hose or pipe to the installation site.

Diese Maschinen sind bauaufwendig,verschleißempfindlich und infolge des relativ hohen Gewichtes ist ein schneller St@ndort= wechsel,wie es die Spritzbetonier-Technik erfordert,erschwert.These machines are complex, sensitive to wear and tear and as a result the relatively high weight means a quick change of location, as is the case with shotcrete technology requires, difficult.

Bei dem bekannten Schaufelrotor/Schneckenprinzip ist neben dem sehr großen Luftbedarf eine erhöhte Rückschlaggefahr und eine erschwerte Schlauchführung am Einbauort.In the known vane rotor / screw principle, in addition to the very large air requirement, an increased risk of kickback and difficult hose routing at the installation site.

Die vorliegende Erfindung ist geeignet,die genannten Mängel zu vermeiden.The present invention is capable of obviating the aforementioned shortcomings.

In einem zweckmäßig geformten Aufgabebehälter 1 ist ein Rührwerk 2, auslaufend in eine Schnecke 3,die in dem am Behälter 1 montierten Zuteilzylinder4 lä.uft.In einem bestimmten Winkel ist ein Förder= rohr 5 mit Schnecke 6 und dem Klappenventil 7 angebracht.Die Schnecke wird durch einen separaten Verstellmot@r geei neter Bauart angetrieben.Das Förderrohr,aus Stahl oder einem für abrasive Stoffe geeigneten Material,mündet in die Abblaskamner 8, Am Ende der Schnecke ist ein zweites Klappentil 7 eingebaut.In an appropriately shaped feed container 1 is an agitator 2, ending in a screw 3, which runs in the metering cylinder 4 mounted on the container 1. A conveyor pipe 5 with screw 6 and the flap valve 7 is attached at a certain angle is driven by a separate adjusting motor of suitable design. The delivery pipe, made of steel or one for abrasive Substances suitable material, opens into the blow-off chamber 8, At the end of the screw a second flap valve 7 is installed.

Der oder die Druckluftanschlüssesind so angeordnet,daß der Luftstrom gerichtet in die Abblaskam@er 8 eintritt.Mit Kupplungen werden die weiterführenden Leitungen angeschlossen.The compressed air connection or connections are arranged so that the air flow directed into the blow-off chamber 8. With couplings, the further Lines connected.

Der aufbau des Gerätes erfolgt aufRähmen oder/und Fahrgestell.The device is set up on the frame and / or the chassis.
