Abstract
Description
Die Erfindung betrifft ein Streugerät nach dem Oberbegriff des Patentanspruches.The invention relates to a spreader according to the preamble of the claim.
Aus der AT 403 559 A ist ein Streugerät bekannt, welches mit Hilfe von der Förderung des Sandes getrennter Dosierung mittels eines axial verschiebbaren Kolbens aufweist. Nach der Dosierung wird das Streugut in einen als Injektor ausgeführte drucklüftbe tätigte Förder- bzw. Austragseinrichtung zum Austragen des Streugutes vorgesehen. Dies bringt den Vorteil mit sich, dass gegenüber Streugeräten, bei denen die Dosierung des Streugutes nicht getrennt von dessen Förderung stattfindet, eine wesentlich ge ringere Menge an Streugut verbraucht wird. Hierbei besteht jedoch die Gefahr, dass eine Rückströmung von Luft in den Kompressor erfolgen kann.From AT 403 559 A a spreader is known, which with Aid from the promotion of sand by means of separate dosing of an axially displaceable piston. After dosing the spreading material is compressed air into an injector operated conveyor or discharge device for discharging the Spreading material provided. This has the advantage that to spreaders where the dosage of the spreading material is not separate from its funding, a significant ge less amount of grit is consumed. However, there is the risk of a backflow of air into the compressor can be done.
Durch den Abstract JP 4038204 A ist ein Streugerät der eingangs erwähnten Art bekannt geworden, bei welchem zwischen einem Gebläse zum Austragen des Streugutes und einem Druckluft behälter elektromagnetisch gesteuerter Ventile und dem Druck luftbehälter und den Kompressoren Rückschlagventile vorgesehen sind. Der Nachteil dieser Anlage besteht darin, dass bei Ver stopfung der sandfördernden Leitung die Druckluft nicht oder nicht ausreichend über diese Leitung expandieren kann. Auch der durch Fahrgeschwindigkeit entstehende Staudruck wirkt auf die Sandaustragsöffnung und hat zur Folge, dass Feuchtigkeit in den Sandvorratsbehälter bzw. in den Kompressor gelangt, wodurch der Sand im Vorratsbehälter verklumpt und/oder die Feuchtigkeit im Kompressor Schäden verursacht.The abstract JP 4038204 A is a spreader became known in the beginning, in which between a blower for discharging the spreading material and compressed air container of electromagnetically controlled valves and the pressure air tank and the compressors check valves provided are. The disadvantage of this system is that Ver blockage of the sand-conveying line does not the compressed air or cannot expand sufficiently via this line. Also the back pressure caused by driving speed affects the Sand discharge opening and has the consequence that moisture in the Sand storage container or gets into the compressor, whereby the Sand clumps in the storage container and / or the moisture in the Compressor causes damage.
Ziel der Erfindung ist es, die Nachteile der zuvor be schriebenen bekannten Streugeräte zu vermeiden.The aim of the invention is to overcome the disadvantages of the previously to avoid known spreading devices.
Dieses Ziel wird bei einem erfindungsgemäßen Streugerät der eingangs angeführten Art durch die Maßnahme nach dem kennzeich nenden Teil des Anspruches erreicht. Ohne diese Maßnahme könnte eine Expansion nur über den vorgeschalteten Kompressor erfolgen. Dadurch würde sich eine gegenläufige Strömung einstellen, die wiederum den Sand in den Kompressor fördern kann und diesen zer stört. This goal is in a spreader according to the invention type mentioned at the beginning by the measure according to the label reached part of the claim. Without this measure expansion only via the upstream compressor. This would create an opposite flow, the can in turn convey the sand into the compressor and destroy it disturbs.
Die Erfindung wird nachstehend an Hand eines Ausführungs beispiels, auf das sie jedoch nicht beschränkt sein soll, noch weiter erläutert. Die einzige Figur zeigt eine schematische Blockschaltbilddarstellung des Streugerätes.The invention is described below with the aid of an embodiment example, to which it should not be limited, however explained further. The only figure shows a schematic Block diagram representation of the spreader.
Im Blockschaltbild des Streugerätes 1 ist mit 2 ein Vor ratsbehälter bezeichnet, der mit einer Dosiervorrichtung 3 ver bunden ist. Die Dosiervorrichtung kann beliebig ausgeführt sein. Sie kann beispielsweise als verschiebbarer Kolben, z. B. nach der AT 403 559 A oder eine um eine Drehachse rotierbare Förder- bzw. Verschlussfläche, z. B. Zellenradschleuse, ausgeführt sein. Der Dosiervorrichtung 3 folgt in Strömungsrichtung des Streugutes, im vorliegenden Falle ein Injektor 5, aus welchem das Streugut, beispielsweise ein Sandgut, über eine Sandschlauchleitung 11 zum Streurohr 12 gefördert wird, aus welchem es als Antirutschmate rial für ein Rad 13 austritt. Die Druckluftbeaufschlagung erfolgt mittels eines Kompressors 8, der von einem Druckspeicher 7 ange speist wird, und mit dem Injektor 5 über einen Druckluftschlauch 9 verbunden ist.In the block diagram of the spreader 1 , 2 denotes a storage container, which is connected to a metering device 3 . The metering device can be of any design. You can, for example, as a displaceable piston, for. B. according to AT 403 559 A or a conveying or sealing surface rotatable about an axis of rotation, for. B. rotary valve can be executed. The metering device 3 follows in the flow direction of the grit, in the present case an injector 5 , from which the grit, for example sand, is conveyed via a sand hose line 11 to the spreader pipe 12 , from which it emerges as an anti-slip material for a wheel 13 . The compressed air is applied by means of a compressor 8 , which is fed by a pressure accumulator 7 , and is connected to the injector 5 via a compressed air hose 9 .
Zwischen der druckluftbetätigten Förder- bzw. Austragsvor richtung 5 und dem für die Druckluftzufuhr vorgesehenen Kompres sor 8 ist ein Rückschlagventil 10 vorgesehen. Das Rückschlagventil 10 dient zum Schutz des Kompressors 8, da bei sogenannten Zweirichtungsfahrzeugen derartige Streugeräte, in Fahrtrichtung gesehen, an beiden Seiten der Räder 13 angebracht sind. Hierbei ergeben sich Staudrücke im Bereich der Förderlei tung 11 bei den entgegen der aktuellen Fahrtrichtung angebrachten Streugeräten, welche sich im System in dynamische Drücke umsetzen können und hierdurch eine unerwünschte Rückförderung von Luft in Richtung des Kompressors 8 bewirkt würde. Die rückströmende Luft würde nämlich Feuchtigkeit und Staub bzw. Sandpartikel in das System bringen, wodurch es zu einer Blockade des Streugerätes 1 kommen würde.A check valve 10 is provided between the compressed air-operated conveying or discharge device 5 and the compressor 8 provided for the compressed air supply. The check valve 10 serves to protect the compressor 8 , since in so-called two-way vehicles such spreading devices, as seen in the direction of travel, are attached to both sides of the wheels 13 . This results in dynamic pressures in the area of the conveying line 11 in the case of the spreading devices mounted counter to the current direction of travel, which can be converted into dynamic pressures in the system and would thereby cause undesired return flow of air in the direction of the compressor 8 . The returning air would namely bring moisture and dust or sand particles into the system, which would result in a blockage of the spreading device 1 .
