Description

Die Erfindung betrifft eine fahrbare Vorrichtung zum Mischen und Auftragen von Gesteinsstoffen und einem bituminösen Bindemittel für den Straßenbau mit je einem Verteiler für die Gesteinsstoffe und das Bindemittel.The invention relates to a mobile device for mixing and applying rock materials and a bituminous binder for road construction with one distributor each for the rock and the binding agent.

Bei den bekannten Vorrichtungen dieser Art werden die zu mischenden Baustoffe gleichzeitig auf die Straße geschleudert. Hierbei sind die Verteiler derart angeordnet, daß die Gesteinsstoffe auf dem Wege zur Straßenoberfläche in den Bereich des Bindemittelstrahls gelangen und vor dem Auftreffen auf die Straßenoberfläche von dem Bindemittel benetzt werden. So hergestellte Straßenbeläge haften indessen nicht immer gut am Untergrund, insbesondere wenn dieser rauh ist, da keine besondere Klebeschicht vorhanden ist. Zur Erzielung eines völligen Anhaftens des Belages am Untergrund ist es nötig, den letzteren vorher mit einem Bindemittel, wie Teer, Asphalt o. dgl., zu überziehen. Außerdem ist es, damit der Verkehr nicht behindert wird, erforderlich, den Belag in üblicher Weise mit Sand oder Splitt zu bedecken. Es sind also drei aufeinanderfolgende Arbeitsgänge erforderlieh, um einen an der Unterlage gut haftenden, sofort befahrbaren Belag zu erhalten.In the known devices of this type, the building materials to be mixed are simultaneously thrown into the street. Here, the distributors are arranged in such a way that the rock matter get into the area of the binder jet on the way to the road surface and are wetted by the binder before hitting the road surface. So made Road surfaces, however, do not always adhere well to the ground, especially if it is rough, as there is no special adhesive layer is available. To achieve complete adhesion of the covering to the substrate, it is necessary to to coat the latter beforehand with a binding agent such as tar, asphalt or the like. aside from that it is necessary, so that the traffic is not obstructed, the surface in the usual way cover with sand or grit. So three consecutive work steps are required, in order to obtain a surface that adheres well to the base and is immediately passable.

Nach der vorliegenden Erfindung soll ein derartiger Belag in einem Arbeitsgang mit im wesentlichen denselben Mitteln hergestellt werden.According to the present invention, such a covering should in one operation with essentially the same means.

Zu diesem Zwecke sind gemäß der Erfindung die beiden Verteiler als Streudüsen mit kegelförmiger Streuzone ausgebildet und in Fahrtrichtung hintereinander, und zwar der Verteiler für das Bindemittel vorn und der Verteiler für die Gesteinsstoffe hinten, derart angeordnet, daß sich die Streuzonen der Verteiler schneiden. Dadurch, daß sich die Streuzonen teilweise überschneiden, wird in einem einzigen Arbeitsgang ein Belag aus drei übereinanderliegenden Schichten erzielt, von denen die erste aus Teer allein, die zweite aus Gesteinsstoffen mit einem Teerüberzug, die dritte aus Gesteinsstoffen allein besteht.For this purpose, according to the invention, the two distributors are designed as diffuser nozzles with a conical shape Scatter zone formed and one behind the other in the direction of travel, namely the distributor for the binding agent at the front and the distributor for the rock material at the rear, arranged in such a way that the scattering zones of the distributors intersect. Because the scattering zones partially overlap, a covering of three superimposed layers is created in a single operation achieved, of which the first is made of tar alone, the second of rock with a tar coating, the third consists of rock materials alone.

Eine besondere Ausführungsform der Vorrichtung, nach der Erfindung kennzeichnet sieb dadurch, daß die Verteiler gegeneinander verschieblich sind, damit ihr Abstand voneinander verändert werden kann.A particular embodiment of the device according to the invention features sieve in that the distributors are mutually displaceable, so that their distance from one another can be changed.

Zweckmäßig werden zum Auftragen der Baustoffe solche Düsen bekannter Bauart verwendet, die mehrere konzentrische Ringöffnungen besitzen, bei denen also die Stoffe in den Mantelflächen mehrerer gleichachsiger Kegel auf die Straße gelangen.Appropriately, such nozzles of known design are used to apply the building materials, which have several concentric ring openings, in which the substances in the jacket surfaces several coaxial cones get on the road.

In der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise veranschaulicht, und zwar zeigen:In the drawing, the invention is illustrated in one embodiment, for example, namely show:

Abb. 2 schematisch den Grundriß des Fahrzeugs und der sich überschneidenden Streukegel, Fig. 2 schematically shows the ground plan of the vehicle and the intersecting scatter cones,

Abb. 3 und 4 in größerem Maßstabe einen lotrechten Schnitt durch Düsen bekannter Bauart zur Verteilung der Gesteinsstoffe.Figs. 3 and 4 show a vertical on a larger scale Section through nozzles of known design for distributing the rock.

Mit ι ist das Fahrgestell des Fahrzeugs bezeichnet. Das Fahrgestell kann auch aus mehreren hintereinandergekuppelten selbständigen Teilen mit regelbarem Abstand voneinander bestehen. Das Fahrgestell 1 ist auf vier Rädern 2 gelagert und kann z. B. zu einem Kraftfahrzeug gehören oder selbständig und mit einem Schlepper kuppelbar sein. Ein Behälter 3, welcher mit »5 Wärmeschutzmantel versehen ist, ist auf dem Vorderteil des Fahrgestells gelagert und dient zur Aufnahme des Bindemittels. 4 ist eine an sich bekannte umlaufende Düse und dient dazu, die Flüssigkeit in einer kegelförmigen Zone 5 auf die Straßendecke zu verteilen. Die Düse 4 ist mit dem Behälter 3 durch eine Leitung 6 verbunden, die durch den Hahn 7 geöffnet und geschlossen werden kann. Die Drehung der Düse 4 wird von dem Motor 8 aus durch eine endlose Kette 9 oder ein ähnliches Kraftübertragungsmittel bewirkt. The chassis of the vehicle is denoted by ι. The chassis can also consist of several independent parts coupled one behind the other with adjustable spacing from one another. The chassis 1 is mounted on four wheels 2 and can, for. B. to a motor vehicle belong or be independent and can be coupled with a tractor. A container 3, which with »5 heat protection jacket is provided, is mounted on the front part of the chassis and is used to take up the binding agent. 4 is a known rotating nozzle and is used to to distribute the liquid in a conical zone 5 on the road surface. The nozzle 4 is connected to the container 3 by a line 6 which is opened and closed by the tap 7 can be. The rotation of the nozzle 4 is effected from the motor 8 by an endless chain 9 or a similar power transmission means.

Für die Gesteinsstoffe ist auf dem Fahrgestell 1 ein Behälter 10 vorgesehen, der die für die Förderung der Gesteinsstoffe erforderlichen Transportmittel enthält.For the rock materials, a container 10 is provided on the chassis 1, which is used for the promotion the rock material contains the necessary means of transport.

In dem Boden des Behälters 10 ist ein sich drehender Verteiler 11 angeordnet. Dieser enthält, wie die Abb. 3 und 4 zeigen, zweckmäßig mehrere durch zylindrische Zwischenwände voneinander getrennte konzentrische Ringöffnungen. In the bottom of the container 10 a rotating distributor 11 is arranged. This contains as Figs. 3 and 4 show, expediently several by cylindrical partitions from each other separate concentric ring openings.

Zum Festpressen der Baustoffe auf die Straßendecke dient eine in bekannter Weise vor den hinteren Laufrädern 2 des Fahrgestells 1 angeordnete mehrteilige Walze 27.For pressing the building materials onto the pavement, one is used in a known manner in front of the Multi-part roller 27 arranged on the rear running wheels 2 of the chassis 1.

Der vordere, den Behälter 3 tragende Aufbau des Fahrgestells 1 ist auf diesem mittels der Leitspindel 24 verschiebbar. Auf diese Weise kann der Abstand der Verteiler und damit der Abstand der beiden kegelförmigen Streuzonen geregelt werden. Durch die Abstandsänderung der Verteiler ist eine Regelung des Mengenverhältnisses der die drei Schichten bildenden Baustoffe möglich.The front, the container 3 supporting structure of the chassis 1 is on this by means of Lead screw 24 displaceable. In this way, the distance between the manifold and thus the Distance between the two conical scattering zones can be regulated. By changing the distance the distributor is a regulation of the proportions of the building materials forming the three layers possible.

Als seitliche Begrenzung des Streuraumes dienen zwei Schutzbleche 37 und 38 (Abb. 2). Die Baustoffe werden gleichzeitig in kegelförmigen Zonen ausgestreut, und zwar aus der Düse 4 das Bindemittel und aus der Düse 11 die Gesteinsstoffe. Da die Streuzonen sich teilweise kreuzen, so erfolgt in der gemeinsamen Teilzone das Überziehen der Gesteinsstoffe mit dem Bindemittel, während in den beiden anderen Teilzonen die Baustoffe unvermengt abgelagert werden, und zwar, in der Fahrtrichtung gesehen, das Bindemittel vorn und die Gesteinsstoffe hinten. Es lassen sich daher mittels nur zweier Verteiler und in einem einzigen Arbeitsgang Beläge aus drei Schichten herstellen, welche übereinandergelagert sind, und zwar derart, daß die unterste aus dem Bindemittel allein, die mittlere aus mit dem Bindemittel überzogenen Gesteinsstoffen und die oberste aus Gesteinsstoffen allein bestehen. Two protective plates 37 and 38 serve as a lateral delimitation of the litter space (Fig. 2). At the same time, the building materials are scattered in conical zones from the Nozzle 4 the binder and from the nozzle 11 the rock. Since the scattering zones are partially cross, the rock material is covered in the common sub-zone the binder, while the building materials are deposited unmixed in the other two sub-zones seen in the direction of travel, the binding agent in front and the rock material in the back. It can therefore only be used two distributors and, in a single operation, produce coverings from three layers, which are superimposed, in such a way that the lowest from the binder alone, the the middle consist of rock matter coated with the binding agent and the uppermost consist of rock matter alone.

Die Arbeit mit der beschriebenen Vorrichtung ist besonders vorteilhaft, wenn die zu belegende Straße eine solche Beschaffenheit besitzt, daß eine gute Haftung der mit einem Bindemittel überzogenen Gesteinsstoffe an der Straßendecke nicht ohne weiteres zu erzielen ist, und wenn es nötig ist, die Straße vorher mit einem Bindemittel, wie Teer oder Asphalt, zu überziehen. Dies erfordert einen besonderen Arbeitsgang, welcher bei Verwendung der Vorrichtung nach der Erfindung in Fortfall kommen kann. Außerdem kann bei Verwendung der beschriebenen Vorrichtung die Straße in kurzer Zeit nach dem Belegen befahren werden, da die oberste Schicht des Belags nur aus Gesteinsstoffen besteht.Working with the device described is particularly advantageous when the Road has such a constitution that good adhesion with a binder Coated stone material on the road surface cannot be achieved without further ado, and if so it is necessary to coat the road with a binding agent such as tar or asphalt beforehand. This requires a special operation, which when using the device after the invention can come to an end. In addition, when using the described Fixture to be driven on the road in a short time after paving as the top layer the pavement consists only of rock material.

Durch Ändern des Abstandes der Streuzonen läßt sich das Mengenverhältnis der die einzelnen Schichten bildenden Baustoffe regeln.By changing the distance between the scattering zones, the quantitative ratio of the individual Regulate building materials that form layers.
