Definitions
- the invention relates to a truck mixer with a water system and a water pump for generating the required water pressure in the water system and with other energy consumers.
- Energy consumers or, in short, consumers who are mounted on the truck mixer are also referred to as additional consumers. These include, in addition to the water system, for example, the chute adjustment, the drum closure, an additive pump for providing additives that change the property of the concrete, and other electrical consumers, such as a camera, work lights or the like.
- the biggest consumer is the water system. On the one hand, it serves to clean the truck mixer after use and, on the other hand, to improve the fluidity of the mixed material. It can also serve to process dry mix to concrete.
- a 500 l or a 650 l water tank is provided, which can be filled via appropriate pipelines.
- the tank is usually mounted by means of a console on the truck mixer gearbox. Schematically, such a structure is in the FIG.
- a water tank 9 via a main line 11, which is externally mounted on the frame, via a riser, which optionally has a water meter 14 and a strainer 12, connected to an injection nozzle, which projects into the drum of the vehicle mixer.
- a cleaning hose 16 goes away from the manifold on the main line 11 down.
- a second injection pipe can be arranged above the inlet funnel.
- FIG. 1 a compressed air water system is shown in which the pressure is generated via the compressed air connection to the vehicle.
- a pressure tank 1 is arranged on the vehicle.
- the compressed air is removed from the compressed air connection of the chassis.
- protection and safety valves such as the four-circuit protection valve 2 and the overflow valve 3, the systems of the vehicle, such as the brake system, are protected. These systems have priority.
- the air requirement of the secondary consumers must be checked to avoid damage to the pressure components, such as the compressor and the air dryer.
- a safety valve 7 and a test port 8 are still present.
- With 10 two Kugelabsperrschieber for filling the water tank 9 are designated.
- Kugelabsperrschieber 13 and 15 are provided to turn on the cleaning hose 16 and the injection nozzle in the drum.
- FIG. 1 illustrated embodiment operates the water system via a water pump, which is driven via the gear of the mixer drum.
- the mixer gear has an additional connection flange on the side of the main flange.
- the water tank is not designed here as a pressure tank.
- the disadvantage is that the pump only promotes when the drum rotates. The delivery volume depends on the speed of the drum. It should be noted that the pump must not be operated with recycled water or water with additives. Furthermore Do not allow the pump to run dry. If there is a risk of frost, the water system must always be emptied, with the ball shut-off valve 10 in accordance with FIG. 1 to open.
- the water pump can also be switched via hydraulic.
- a gear pump is flanged, which drives the hydraulic motor.
- This engine supplies the water pump.
- the drive is only dependent on the speed of the drive motor of the vehicle, usually a diesel engine. By a valve block this drive is separately switchable.
- An extension of the hydraulic circuit is necessary for this embodiment. Again, the water system is to dehydrate at the risk of frost.
- Another drive option is that the water pump is driven by a V-belt drive from a separate motor.
- the pump is mounted here on a tensioning station.
- the delivery rate here, however, depends on the engine speed of the engine. All of the aforementioned drive variants show considerable disadvantages in terms of space requirements or the dependence on other operating systems of the truck mixer, so that there are not insignificant restrictions when operating the energy consumer.
- the object of the invention is to develop a truck mixer such that potential energy consumers of the truck mixer can be used largely independently and as needed.
- the water pump and / or at least one other consumer is driven by an electric motor in a truck mixer with a water system and a water pump to generate the required water pressure in the water system and with other energy consumers.
- This embodiment of the invention has a number of advantages over the systems initially shown.
- the water tank no longer needs to be located at a specific location of the truck mixer. Rather, on the one hand its shape can be chosen freely, so that it can be adapted to Störkonturen the vehicle chassis. Since gravity no longer depends on the water tank, it can be located at a low point of the chassis so that the center of gravity of the entire truck mixer can be lower. As a result, in particular the driving characteristics of the truck mixer and driving safety are improved.
- a plastic tank can be used and, overall, the water pipes can be shortened.
- the drive power of the electric motor can be provided via the electrical system of the truck mixer.
- the drive energy of the electric motor can be provided via an additionally mounted energy source.
- a controller between the electric motor or the electric motors and the power source.
- a high-pressure cleaner and / or a linear drive and / or a drum closure and / or a chute adjustment and / or an additive pump can be provided.
- chute adjustment and the drum closure can be driven by an effective chain of electric motor and hydraulic drive.
- FIG. 2 a first embodiment of the invention is shown, wherein only a circuit detail is shown here. So here is designated by a water pump 100, which water from a not shown here but not shown on the vehicle mixer arranged water tank and a not shown here water nozzle or other consumer, such as a water hose, can be supplied.
- the water pump is directly driven by an electric motor.
- the electric motor will after the in FIG. 2 shown embodiment fed from the electrical system of the chassis of the truck mixer not shown here.
- a battery 104 is shown, which is powered by a generator 106.
- the generator 106 is driven by the diesel engine 108, which serves to drive the truck mixer. In the embodiment shown here, the diesel engine 108 serves both to propel the truck mixer and to drive the drum.
- FIG. 3 a modified embodiment is shown, in which for the drum drive, which is schematically indicated here with 112, a separate drive 110 is provided. This is a drive shaft 114 with the drum drive 112 feeding generator 116 coupled. To the generator and the electric motor 102 is connected, which in turn drives the water pump 100.
- a further modified embodiment of the invention results from the illustration according to FIG. 4 ,
- the separate drive 110 is also coupled via a propeller shaft 114 with a generator 116.
- the generator drives the drum drive 112 and the electric motor 102, which in turn supplies the water pump 100 with electrical energy.
- upstream of the electric motor 102 is a controller 118 which controls the supply of electrical energy from the generator.
- a separate drive 110 is initially coupled to a generator 116 via a cardan shaft 114.
- the generator initially serves to supply the drum drive 112 and is further coupled via a controller 118 to an electric motor 102, which in turn drives a water pump 100.
- a high-pressure cleaner is additionally connected, which is provided for cleaning the truck mixer.
- the water pressure on up to 140 bar at 15 I / min is achieved, with the cleaning usually the water at a pressure of 80 bar to 100 bar is retrieved because it shows the best cleaning effect at this pressure.
- a corresponding pump 120 which serves to pump the water supplied to the high-pressure cleaner, can be connected to the electric motor.
- a linear drive 122 can be selectively connected to the electric motor.
- a linear drive 122 can be selectively connected to the electric motor.
- So are either different consumers 100, 120 and 122 simultaneously or separately from a single electric motor 102 drivable.
- FIG. 6 one of the embodiment according to FIG. 5 similar version shown, in which again via a drive 110 and a propeller shaft 114, a generator 116 is driven, which serves to supply the drum drive 112 with electrical energy.
- the generator 116 is connected via a controller 118 to a plurality of consumers.
- the first consumer first a water pump 100 of the water system not otherwise shown here driven by a separate electric motor 102.
- the other two consumers are each driven by their own electric motors 102 'and 102 ".
- the consumer which is driven by its own electric motor 102', is an additive pump 124
- the additives are agents which are added to the concrete to influence its behavior and have been injected into the mixing drum by means of a pressurized container or by gravity In the embodiment shown here they are driven by the electrically driven additive pump 124 promoted.
- a hydraulic pump 126 is driven, which in each case further hydraulic consumers are connected via valves 128, 130.

Abstract
Description
Die Erfindung betrifft einen Fahrmischer mit einer Wasseranlage und einer Wasserpumpe zum Erzeugen des benötigten Wasserdruckes in der Wasseranlage und mit weiteren Energieverbrauchern.The invention relates to a truck mixer with a water system and a water pump for generating the required water pressure in the water system and with other energy consumers.
Energieverbraucher oder kurz gesagt Verbraucher, die am Fahrmischer montiert sind, werden auch als Zusatzverbraucher bezeichnet. Zu diesen zählen neben der Wasseranlage beispielsweise die Schurrenverstellung, der Trommelverschluß, eine Zusatzmittelpumpe zum Bereitstellen von Zusatzmitteln, die die Eigenschaft des Beton verändern, und weitere elektrische Verbraucher, wie beispielsweise eine Kamera, Arbeitsscheinwerfer oder ähnliches. Der größte Verbraucher ist die Wasseranlage. Sie dient zum einen dazu, den Fahrmischer nach dem Einsatz zu reinigen und zum anderen dazu, die Fließfähigkeit des Mischmaterials zu verbessern. Sie kann auch dazu dienen, Trockenmischgut zu Beton zu verarbeiten. Standardmäßig wird ein 500 I bzw. ein 650 I Wassertank vorgesehen, der über entsprechende Rohrleitungen befüllbar ist. Der Tank wird üblicherweise mittels einer Konsole auf dem Fahrmischergetriebe montiert. Schematisch ist ein derartiger Aufbau in der
Es existieren unterschiedliche Varianten, die Wasseranlage zu betreiben.There are different variants to operate the water system.

Zum Betreiben der Wasseranlage kann die Wasserpumpe auch über Hydraulik schaltbar sein. An die Fahrmischerpumpe mit Durchtrieb ist dann eine Zahnradpumpe angeflanscht, die den Hydraulikmotor antreibt. Dieser Motor versorgt die Wasserpumpe. Der Antrieb ist nur abhängig von der Drehzahl des Antriebsmotors des Fahrzeugs, üblicherweise eines Dieselmotors. Durch einen Ventilblock ist dieser Antrieb separat schaltbar. Eine Erweiterung des Hydraulikkreislaufes ist für diese Ausführungsvariante notwendig. Auch hier ist die Wasseranlage bei Frostgefahr zu entwässern.To operate the water system, the water pump can also be switched via hydraulic. To the truck mixer pump with through drive then a gear pump is flanged, which drives the hydraulic motor. This engine supplies the water pump. The drive is only dependent on the speed of the drive motor of the vehicle, usually a diesel engine. By a valve block this drive is separately switchable. An extension of the hydraulic circuit is necessary for this embodiment. Again, the water system is to dehydrate at the risk of frost.
Eine andere Antriebsmöglichkeit besteht darin, dass die Wasserpumpe über einen Keilriemenantrieb von einem separaten Motor angetrieben wird. Die Pumpe ist hier auf einer Spannstation montiert. Die Förderleistung ist hier allerdings abhängig von der Motordrehzahl des Motors. Sämtliche vorgenannten Antriebsvarianten zeigen erhebliche Nachteile hinsichtlich des Platzbedarfs bzw. der Abhängigkeit von anderen Betriebssystemen des Fahrmischers, so dass beim Betreiben der Energieverbraucher nicht unerhebliche Einschränkungen bestehen.Another drive option is that the water pump is driven by a V-belt drive from a separate motor. The pump is mounted here on a tensioning station. The delivery rate here, however, depends on the engine speed of the engine. All of the aforementioned drive variants show considerable disadvantages in terms of space requirements or the dependence on other operating systems of the truck mixer, so that there are not insignificant restrictions when operating the energy consumer.
Aufgabe der Erfindung ist es, einen Fahrmischer derart weiterzubilden, dass mögliche Energieverbraucher des Fahrmischers weitgehend unabhängig und bedarfsgerecht eingesetzt werden können.The object of the invention is to develop a truck mixer such that potential energy consumers of the truck mixer can be used largely independently and as needed.
