Definitions

  • the invention relates to a vehicle for beach cleaning according to the preamble of claim 1.
  • Such a vehicle is known from US-A-2976936.
  • This vehicle has a garbage pick-up that is adjustable on the vehicle frame.
  • This includes a receiving wedge bar and a downstream conveyor. This extends through an opening in the vehicle frame from approximately a beach surface to above a collection container suspended at the rear of the vehicle.
  • a disadvantage of the known vehicle is that the garbage picked up is raised relatively far above the ground, as a result of which the garbage can be removed from the garbage collector or conveyor by environmental influences such as wind, rain or the like.
  • Another disadvantage is that the volume of the collecting container is relatively small, so that beach cleaning often has to be interrupted in order to empty the collecting container in a waste transfer station. This leads to an increased workload and an extension of the work involved in beach cleaning.
  • the invention is therefore based on the object of providing a versatile vehicle of the type mentioned, which is improved in particular with regard to refuse collection and the period of use.
  • the garbage collector and the conveyor are arranged below a loading area, and at the same time the collecting container can be emptied over the loading area, the garbage received is transferred to the collecting container in a relatively protected manner.
  • a separation of sand and waste takes place both on the waste collector and on the associated elevator. Due to the detachable arrangement of the garbage pickup below the loading area, it can be easily removed and exchanged for another garbage pickup.
  • a waste pick-up can be attached to the vehicle with a different receiving wedge strip and / or another elevator.
  • the arrangement of the garbage collector below the loading area means that it can also be used for a wide range of applications.
  • the loading area can in particular also serve to hold the waste collected in the collecting container. This significantly increases the vehicle's service life. Since the collecting container is arranged at the rear of the vehicle, it is easily accessible in this position and can also be used as a storage area for other objects if the vehicle is to be used for other municipal tasks than for beach cleaning.
  • a further vehicle that can only be used for beach cleaning is known.
  • This vehicle has a horizontal pick-up roller arranged on the front of the vehicle, which picks up the contaminants and feeds them to a barrel-shaped drum screen via a narrowed, slippery feed.
  • the pick-up roller and the drum screen are pivotably mounted on the vehicle frame between an operating position touching the ground and a standby position raised from the ground by means of an actuating cylinder. From the drum sieve, the garbage is transported to an elevator through an opening in the frame transferred to the frame of the collecting container parked at the rear of the vehicle.
  • a self-picking sweeper is known from DE-A-894399. Gutter brooms and a downstream broom belt with brooms are arranged below the vehicle frame of this sweeper. This transfers the garbage between the rear wheels to a garbage scoop, the brooms conveying the garbage along the garbage scoop to a filling container. This can be emptied on an inclined level, which is arranged within a collecting container.
  • the collecting container is mounted on the vehicle frame and can be pivoted about a pivot axis at the end of the vehicle frame in order to empty the inclined plane.
  • the use of the vehicle is not limited to beach cleaning by the garbage pick-up which is adjustable and / or pivotably mounted on the frame.
  • the vehicle can also be used as a tractor in road traffic when the garbage collector is swung off the ground. This results in a variable work assignment, especially for municipal work.
  • Various attachments can be detachably attached to the front and rear of the vehicle, such as disc mowers, motor mowers, bar mowers, mulchers, sweepers, rotary brushes for cleaning posts and guardrails, snow plows, salt spreaders, fertilizer spreaders, scarifiers or the like.
  • the vehicle can have add-on devices such as special inserts for transporting beach chairs, water containers or the like.
  • a coordination between the width of the garbage pickup and the width of the median strip is important insofar as the entire garbage deposited in the median strip can be picked up and transported away.
  • penetration into a sand-shaped floor and thus also picking up of garbage pressed into the floor is possible.
  • Varying the working depth using the actuator can also be used to remove objects that are deeper into the soil.
  • protection claims 9 and 10 are advantageous in that the waste can be largely separated from the carried soil material with the aid of the conveyor.
  • a jog screen that rises to the rear prevents the garbage from jumping off or sliding as a result of the conveying movement of the screen.
  • finishers can be provided on the rear of the collecting container and / or on the vehicle frame for smoothing the cleaned sand and for a certain compensation of troughs and holes.
  • claims 15 and 16 enable a targeted depositing of the garbage received in the collecting container, as well as a versatile use of the vehicle, e.g. for transporting building materials, soil, gardening items or the like ..
  • the lane cleaning device can have a number of cleaning elements which can be quickly mounted and converted on the vehicle with the aid of a common carrier.
  • cleaning elements can be designed such that they can be lowered into an operating position and raised into a standby position by means of actuating devices.
  • the features of claim 18 are also advantageous since, e.g. in the case of uneven terrain, the cleaning elements cannot penetrate too deeply into the floor and, if necessary, their damage is prevented with the aid of the sliding shoes supported flat on the floor.
  • Plate-shaped sliding shoes also allow sliding in all horizontal directions. Such shock absorption of the cleaning elements by means of the sliding shoes increases the durability and thus the service life of the cleaning elements, in particular when cleaning hilly terrain.
  • the sliding shoes can be height-adjustable with respect to the depth of engagement of the cleaning elements, as a result of which there is extensive adaptation to the nature of the floor to be cleaned.
  • the vehicle can be converted to other areas of application without great expenditure of time, by simple manipulations and without special specialist knowledge guaranteed. This increases the variability and flexibility of the commercial vehicle.
  • a self-propelled commercial vehicle for beach cleaning 1 is shown in its operating position.
  • the commercial vehicle 1 has a front axle 2 and a rear axle 3, on which a vehicle frame 4 is spring-mounted.
  • the ends of the axles are each equipped with at least one vehicle wheel 5.
  • Above the front axle 2 is a conventionally constructed drive motor 6, which acts on one or both axles, e.g. B. a hydraulic drive is provided, which can also drive other devices installed on the vehicle.
  • the front part of the vehicle, in particular above the front axle 2, is surrounded by a driver's cab 7, while the part of the commercial vehicle 1 downstream of the driver's cab 7 has a tiltable loading area 8.

Description

Die Erfindung betrifft ein Fahrzeug für die Strandreinigung nach dem Oberbegriff des Anspruchs 1.The invention relates to a vehicle for beach cleaning according to the preamble of claim 1.

Ein solches Fahrzeug ist aus der US-A-2976936 bekannt. Dieses Fahrzeug weist einen am Fahrzeugrahmen verstellbaren Müllaufnehmer auf. Dieser umfaßt eine Aufnahmekeilleiste und einen nachgeordneten Förderer. Dieser erstreckt sich durch eine Öffnung des Fahrzeugrahmens von in etwa einer Strandoberfläche bis oberhalb eines am Heck des Fahrzeugs aufgehängten Sammelbehälter.Such a vehicle is known from US-A-2976936. This vehicle has a garbage pick-up that is adjustable on the vehicle frame. This includes a receiving wedge bar and a downstream conveyor. This extends through an opening in the vehicle frame from approximately a beach surface to above a collection container suspended at the rear of the vehicle.

Nachteilig bei dem vorbekannten Fahrzeug ist, daß der aufgenommene Müll bis relativ weit über den Boden angehoben wird, wodurch der Müll durch Umwelteinflüsse wie Wind, Regen oder dergleichen, vom Müllaufnehmer beziehungsweise Förderer entfernt werden kann. Außerdem ist von Nachteil, daß das Volumen des Sammelbehälters relativ klein ist, so daß die Strandreinigung oftmals unterbrochen werden muß, um den Sammelbehälter in einer Müllumladestation zu entleeren. Dies führt zu einem vermehrten Arbeitsaufwand und zu einer Verlängerung des Arbeitseinsatzes bei der Strandreinigung.A disadvantage of the known vehicle is that the garbage picked up is raised relatively far above the ground, as a result of which the garbage can be removed from the garbage collector or conveyor by environmental influences such as wind, rain or the like. Another disadvantage is that the volume of the collecting container is relatively small, so that beach cleaning often has to be interrupted in order to empty the collecting container in a waste transfer station. This leads to an increased workload and an extension of the work involved in beach cleaning.

Der Erfindung liegt daher die Aufgabe zugrunde, ein vielseitig einsetzbares Fahrzeug der eingangs genannten Art zu schaffen, das insbesondere hinsichtlich der Müllaufnahme und der Einsatzdauer verbessert ist.The invention is therefore based on the object of providing a versatile vehicle of the type mentioned, which is improved in particular with regard to refuse collection and the period of use.

Diese Aufgabe wird bei einem Fahrzeug der eingangs genannten Art mit den Merkmalen des Kennzeichens des Anspruchs 1 gelöst.This object is achieved in a vehicle of the type mentioned at the outset with the features of the characterizing part of claim 1.

Dadurch daß der Müllaufnehmer und der Förderer unterhalb einer Ladefläche angeordnet sind, wobei gleichzeitig der Sammelbehälter über der Ladefläche entleerbar ist, wird der aufgenommene Müll relativ geschützt zum Sammelbehälter überführt. Eine Separation von Sand und Müll findet sowohl auf dem Müllaufnehmer als auch auf dem zugehörigen Elevator statt. Durch die lösbare Anordnung des Müllaufnehmers unterhalb der Ladefläche ist dieser in einfacher Weise abnehmbar und gegen einen anderen Müllaufnehmer austauschbar. Je nach Einsatzbereich kann beispielsweise ein Müllaufnehmer mit anderer Aufnanmekeilleiste und/oder anderem Elevator am Fahrzeug befestigt werden. Durch die Anordnung des Müllaufnehmers unterhalb der Ladefläche ist diese außerdem für die verschiedensten Einsatzbereiche nutzbar. Die Ladefläche kann insbesondere auch zur Aufnahme des im Sammelbehälter gesammelten Mülls dienen. Dadurch wird die Einsatzdauer des Fahrzeugs erheblich vergrößert. Da der Sammelbehälter am Heck des Fahrzeugs angeordnet ist, ist er in dieser Stellung leicht zugänglich und Kann auch als Ablage für andere Gegenstände verwendet werden, wenn das Fahrzeug für andere kommunale Aufgaben als zur Strandreinigung eingesetzt werden soll.Characterized in that the garbage collector and the conveyor are arranged below a loading area, and at the same time the collecting container can be emptied over the loading area, the garbage received is transferred to the collecting container in a relatively protected manner. A separation of sand and waste takes place both on the waste collector and on the associated elevator. Due to the detachable arrangement of the garbage pickup below the loading area, it can be easily removed and exchanged for another garbage pickup. Depending on the area of application, for example, a waste pick-up can be attached to the vehicle with a different receiving wedge strip and / or another elevator. The arrangement of the garbage collector below the loading area means that it can also be used for a wide range of applications. The loading area can in particular also serve to hold the waste collected in the collecting container. This significantly increases the vehicle's service life. Since the collecting container is arranged at the rear of the vehicle, it is easily accessible in this position and can also be used as a storage area for other objects if the vehicle is to be used for other municipal tasks than for beach cleaning.

Aus der DE-A-3606373 ist ein weiteres ausschließlich für die Strandreinigung einsetzbares Fahrzeug bekannt. Dieses Fahrzeug weist eine an der Fahrzeugfront angeordnete horizontale Pick-up-Walze auf, die die Verunreinigungen aufnimmt und diese über eine verengte, rutschartige Zuführung einem tonnenförmigen Trommelsieb zuführt. Die Pick-up-Walze und das Trommelsieb sind mittels eines Stellzylinders zwischen einer den Boden berührenden Betriebsstellung und einer vom Boden abgehobenen Bereitschaftsstellung am Fahrzeugrahmen schwenkbar gelagert. Vom Trommelsieb wird der Müll über einen Elevator durch eine Öffnung im Rahmen bis zu einem am Heck des Fahrzeugs au dem Rahmen abgestellten Sammelbehälter überführt.From DE-A-3606373 a further vehicle that can only be used for beach cleaning is known. This vehicle has a horizontal pick-up roller arranged on the front of the vehicle, which picks up the contaminants and feeds them to a barrel-shaped drum screen via a narrowed, slippery feed. The pick-up roller and the drum screen are pivotably mounted on the vehicle frame between an operating position touching the ground and a standby position raised from the ground by means of an actuating cylinder. From the drum sieve, the garbage is transported to an elevator through an opening in the frame transferred to the frame of the collecting container parked at the rear of the vehicle.

Aus der DE-A-894399 ist eine selbstaufnehmende Kehrmaschine bekannt. Unterhalb des Fahrzeugrahmens dieser Kehrmaschine sind Rinnenbesen und ein nachgeordnetes Besenband mit Besen angeordnet. Dieses überführt den zwischen den Hinterrädern befindlichen Kehricht an eine Kehrichtschaufel, wobei die Besen den Kehricht entlang der Kehrichtschaufel bis zu einem Füllbehälter befördern. Dieser ist auf eine schiefe Ebene, die innerhalb eines Sammelbehälters angeordnet ist, entleerbar. Der Sammelbehälter ist auf dem Fahrzeugrahmen gelagert und um eine Schwenkachse am Fahrzeugrahmenende zur Entleerung der schiefen Ebene verschwenkbar.A self-picking sweeper is known from DE-A-894399. Gutter brooms and a downstream broom belt with brooms are arranged below the vehicle frame of this sweeper. This transfers the garbage between the rear wheels to a garbage scoop, the brooms conveying the garbage along the garbage scoop to a filling container. This can be emptied on an inclined level, which is arranged within a collecting container. The collecting container is mounted on the vehicle frame and can be pivoted about a pivot axis at the end of the vehicle frame in order to empty the inclined plane.

Im Vergleich zum Stand der Technik ist bei dem erfindungsgemäßen Fahrzeug für die Strandreinigung durch den am Rahmen verstellbar und/oder schwenkbar gelagerten Müllaufnehmer ein Einsatz des Fahrzeugs nicht auf die Strandreinigung beschränkt. Bei vom Boden abgeschwenkten Müllaufnehmer kann das Fahrzeug auch als Zugmaschine im Straßenverkehr eingesetzt werden. Dadurch ergibt sich, insbesondere für kommunale Arbeiten, ein variabler Arbeitseinsatz. An der Fahrzeugvorderseite und -hinterseite können verschiedene Anbaugeräte wahlweise lösbar angebracht sein, wie zum Beispiel Scheibenmähwerk, Motormähwerk, Balkenmähwerk, Mulchwerk, Kehrmaschine, Rotationsbürsten von Leitpfosten- und Schutzplankenreinigung, Schneepflug, Salzstreuer, Düngerstreuer, Vertikutiergeräte oder dergleichen. Außerdem kann das Fahrzeug Aufbaugeräte wie zum Beispiel Spezialeinlagen für Strandkorbtransport, Wasserbehälter oder dergleichen aufweisen.In comparison to the prior art, in the vehicle according to the invention for beach cleaning, the use of the vehicle is not limited to beach cleaning by the garbage pick-up which is adjustable and / or pivotably mounted on the frame. The vehicle can also be used as a tractor in road traffic when the garbage collector is swung off the ground. This results in a variable work assignment, especially for municipal work. Various attachments can be detachably attached to the front and rear of the vehicle, such as disc mowers, motor mowers, bar mowers, mulchers, sweepers, rotary brushes for cleaning posts and guardrails, snow plows, salt spreaders, fertilizer spreaders, scarifiers or the like. In addition, the vehicle can have add-on devices such as special inserts for transporting beach chairs, water containers or the like.

Vorteilhafte Ausgestaltungen des Müllaufnehmers sind den Ansprüchen 2 bis 8 zu entnehmen. Eine Abstimmung zwischen der Breite des Müllaufnehmers und der Breite des Mittelstreifens ist insofern wichtig, als dadurch der gesamte, im Mittelstreifen abgelegte Müll aufgenommen und abtransportiert werden kann. Mit Hilfe der Aufnahmekeilleiste ist ein Eindringen in einen sandförmigen Boden und damit auch ein Aufnehmen von in den Boden eingedrückten Müll möglich. Günstig ist dabei ferner, daß lediglich der Müll von dem Boden aufgenommen wird, während der Sand teilweise schon an der Keilleiste abgeschieden wird. Durch ein Variieren der Arbeitstiefe mittels des Stellantriebs können auch tiefer in den Boden eingedrückte Gegenstände aus diesem entfernt werden. Durch das Ausbilden des Elevators mit Umlenkachsen und einem umlaufenden Trum ist ein schnelles Aufnehmen und Abtransportieren des Mülls zum Sammelbehälter sichergstellt.Advantageous refinements of the garbage collector can be found in claims 2 to 8. A coordination between the width of the garbage pickup and the width of the median strip is important insofar as the entire garbage deposited in the median strip can be picked up and transported away. With the help of the receiving wedge strip, penetration into a sand-shaped floor and thus also picking up of garbage pressed into the floor is possible. It is also advantageous that only the garbage is picked up from the floor, while the sand is already partially separated on the wedge ledge. Varying the working depth using the actuator can also be used to remove objects that are deeper into the soil. By designing the elevator with deflecting axes and a rotating run, the garbage is quickly picked up and transported away to the collecting container.

Die Merkmale der Schutzansprüche 9 und 10 sind insofern vorteilhaft, als mit Hilfe des Förderers ein weitgehendes Trennen des Mülls von dem mitgeführten Bodenmaterial möglich ist. Durch ein nach hinten ansteigendes Rüttelsieb wird ein Herabspringen oder -gleiten des Mülls infolge der Förderbewegung des Siebes verhindert.The features of the protection claims 9 and 10 are advantageous in that the waste can be largely separated from the carried soil material with the aid of the conveyor. A jog screen that rises to the rear prevents the garbage from jumping off or sliding as a result of the conveying movement of the screen.

Außerdem ist eine Weiterbildung des Fahrzeugs gemäß der Schutzansprüche 11 bis 14 zweckmäßig. Mit Hilfe der seitlichen Lenker, die exzentrische Lagerung der horizontalen Schwenkachsen ist mit geeigneten Anschlägen bei einem Verschwenken des Sammelbehälters über die Ladefläche ein automatisches Entleeren des vollen Sammelbehälters über der Ladefläche durch ein Kippen des Behälters ermöglicht. Mit Hilfe des zusätzlichen Stellantriebs ist der Kippunkt des Sammelbehälters variierbar, um eine gleichmäßige Befüllung der Ladefläche zu erzielen. Wird bei einem Sammelbehälter die Rückwand parallel zum Boden ausgebildet, ist in dessen gekippter Stellung auch ein direktes Aufnehmen beispielsweise von Sand bei einem Zurücksetzen des Fahrzeugs und anschließendem Aufrichten des Sammelbehälters mit Hilfe des Stellantriebes möglich. Außerdem kann auch eine Füllstandsanzeige sowie eine Anzeigevorrichtung vorteilhaft sein, da der Sammelbehälter normalerweise nicht vom Fahrersitz aus einsehbar ist.In addition, a further development of the vehicle according to claims 11 to 14 is appropriate. With the help of the side handlebars, the eccentric mounting of the horizontal swivel axes enables the full collection container to be automatically emptied by tilting the container when the collection container is swiveled over the loading area. With the help of the additional actuator, the tipping point of the collecting container can be varied in order to achieve an even filling of the loading area. If the rear wall of a collecting container is formed parallel to the floor, it is also possible in its tilted position to directly pick up sand, for example, when the vehicle is reset and then raise the collecting container with the aid of the actuator. In addition, a fill level indicator and a display device can also be advantageous, since the collecting container is normally not visible from the driver's seat.

Bei einer Ausführungsform der Erfindung können am Heck des Sammelbehälters und/oder am Fahrzeugrahmen zum Glattstreichen des gesäuberten Sandes und zu einem gewissen Ausgleichen von Mulden und Löchern Finisher vorgesehen sein.In one embodiment of the invention, finishers can be provided on the rear of the collecting container and / or on the vehicle frame for smoothing the cleaned sand and for a certain compensation of troughs and holes.

Die Merkmale der Ansprüche 15 und 16 ermöglichen zum einen ein gezieltes Ablegen des in den Sammelbehälter aufgenommenen Mülls, außerdem einen vielfältigen Einsatz des Fahrzeugs, z.B. zum Transportieren von Baumaterialien, Erdreich, Gärtnereiartikel od.dgl..The features of claims 15 and 16 on the one hand enable a targeted depositing of the garbage received in the collecting container, as well as a versatile use of the vehicle, e.g. for transporting building materials, soil, gardening items or the like ..

Durch die Merkmale des Anspruches 17 ist eine Reinigung nicht nur eines Bereiches in der Fahrzeugmitte sondern auch in den Fahrspuren der Räder möglich. Daraus ergibt sich ein rationelles Reinigen einer bestimmten Strandfläche, da pro Arbeitszyklus ein wenigstens der Fahrzeugbreite entsprechender Streifen gereinigt werden kann. Die Fahrspurreinigungseinrichtung kann dabei eine Anzahl von Reinigungselementen aufweisen, die mit Hilfe eines gemeinsamen Trägers schnell montierbar und umrüstbar am Fahrzeug angebracht werden. Als Reinigungselemente sind beispielsweise gegenläufig angetriebene Rotorschwader, gewendelte Schnecken oder Bürstenrollen verwendbar. Die Reinigungselemente können mittels Betätigungseinrichtungen absenkbar in eine Betriebsstellung sowie anhebbar in eine Bereitschaftsstellung ausgebildet sein.Due to the features of claim 17, cleaning is not only an area in the middle of the vehicle but also possible in the lanes of the wheels. This results in a rational cleaning of a certain beach area, since a strip at least corresponding to the width of the vehicle can be cleaned per work cycle. The lane cleaning device can have a number of cleaning elements which can be quickly mounted and converted on the vehicle with the aid of a common carrier. For example, counter-rotating rotor rakes, coiled screws or brush rollers can be used as cleaning elements. The cleaning elements can be designed such that they can be lowered into an operating position and raised into a standby position by means of actuating devices.

Vorteilhaft sind ferner die Merkmale des Anspruches 18, da, z.B. bei unebenem Gelände, ein zu tiefes Eindringen der Reinigungselemente in den Boden und ggf. deren Beschädigung mit Hilfe der flächig auf dem Boden abgestützten Gleitschuhe verhindert ist. Tellerförmig ausgestaltete Gleitschuhe ermöglichen darüberhinaus ein Gleiten in allen horizontalen Richtungen. Eine solche Stoßabdämpfung der Reinigungselemente durch die Gleitschuhe erhöht die Haltbarkeit und damit die Lebensdauer der Reinigungselemente insbesondere beim Reinigen von hügeligem Gelände. Die Gleitschuhe können bezüglich der Eingriffstiefe der Reinigungselemente höhenverstellbar sein, wodurch eine weitgehende Anpassung an die Beschaffenheit des zu reinigenden Bodens gegeben ist.The features of claim 18 are also advantageous since, e.g. in the case of uneven terrain, the cleaning elements cannot penetrate too deeply into the floor and, if necessary, their damage is prevented with the aid of the sliding shoes supported flat on the floor. Plate-shaped sliding shoes also allow sliding in all horizontal directions. Such shock absorption of the cleaning elements by means of the sliding shoes increases the durability and thus the service life of the cleaning elements, in particular when cleaning hilly terrain. The sliding shoes can be height-adjustable with respect to the depth of engagement of the cleaning elements, as a result of which there is extensive adaptation to the nature of the floor to be cleaned.

Mit Hilfe des lösbaren Schnellverschlusses gemäß Schutzanspruch 19 ist ein Umrüsten des Fahrzeuges auf andere Einsatzgebiete ohne großen Zeitaufwand, durch einfache Handgriffe und ohne spezielles Fachwissen gewährleistet. Die Variabilität und Flexibilität des Nutzfahrzeuges wird dadurch noch erhöht.With the help of the releasable quick-release fastener according to protection claim 19, the vehicle can be converted to other areas of application without great expenditure of time, by simple manipulations and without special specialist knowledge guaranteed. This increases the variability and flexibility of the commercial vehicle.

In Fig. 1 ist ein selbstfahrendes Nutzfahrzeug für die Strandreinigung 1 in dessen Betriebsstellung dargestellt. Das Nutzfahrzeug 1 weist eine Vorderachse 2 und eine Hinterachse 3 auf, auf denen ein Fahrzeugrahmen 4 federnd gelagert ist. Die Enden der Achsen sind jeweils mit wenigstens einem Fahrzeugrad 5 bestückt. Oberhalb der Vorderachse 2 ist ein herkömmlich aufgebauter, auf eine oder beide Achsen wirkender Antriebsmotor 6,z. B. ein Hydraulikantrieb, vorgesehen, der darüber hinaus auch weitere, an dem Fahrzeug installierte Einrichtungen antreiben kann. Der vordere Teil des Fahrzeugs, insbesondere oberhalb der Vorderachse 2, ist von einer Fahrerkabine 7 umgeben, während der der Fahrerkabine 7 nachgeordnete Teil des Nutzfahrzeugs 1 eine kippbare Ladefläche 8 aufweist.In Fig. 1, a self-propelled commercial vehicle for beach cleaning 1 is shown in its operating position. The commercial vehicle 1 has a front axle 2 and a rear axle 3, on which a vehicle frame 4 is spring-mounted. The ends of the axles are each equipped with at least one vehicle wheel 5. Above the front axle 2 is a conventionally constructed drive motor 6, which acts on one or both axles, e.g. B. a hydraulic drive is provided, which can also drive other devices installed on the vehicle. The front part of the vehicle, in particular above the front axle 2, is surrounded by a driver's cab 7, while the part of the commercial vehicle 1 downstream of the driver's cab 7 has a tiltable loading area 8.

Der Fahrzeugrahmen 4 besteht aus einem vorderen, 4a, mittleren, 4b und hinteren Abschnitt 4c. Der mittlere Abschnitt 4b weist eine mittige rechteckige Öffnung 9 auf, die durch zwei voneinander beabstandete, quer zur Fahrzeuglängsrichtung sich erstreckende Querträger 10 und durch zwei voneinander beabstandete, in Fahrzeugslänsrichtung sich erstreckende Längsträger 11 begrenzt ist, deren Enden jeweils mit den Querträgern verbunden sind. In der Öffnung 9 ist ein Müllaufnehmer 12 verstellbar gelagert, der aus einer dem Boden 13 berührenden Betriebsstellung (s. Fig. 1) in eine von dem Boden abgehobene Bereitschaftsstellung (s. Fig. 7) und umgekehrt verschwenkbar ist.The vehicle frame 4 consists of a front, 4a, middle, 4b and rear section 4c. The central section 4b has a central rectangular opening 9, which is delimited by two spaced-apart cross members 10 extending transversely to the vehicle longitudinal direction and by two spaced-apart longitudinal members 11 extending in the vehicle longitudinal direction, the ends of which are each connected to the cross members. A waste pickup 12 is adjustably mounted in the opening 9 and can be pivoted from an operating position touching the floor 13 (see FIG. 1) into a standby position raised from the floor (see FIG. 7) and vice versa.

Der vordere und der hintere Querträger 10a, 10b weisen eine identische Länge auf, die die Breite 12a des Müllaufnehmers 12 derartig übersteigt, daß beidseits zwischen dem Müllaufnehmer 12 und den Längsträgern 11 ein etwa gleich großes Spiel 14 (vgl. Fig. 2) vorhanden ist. Die Länge beider Längsträder und damit der lichte Abstand zwischen den Querträgern 10 entspricht in etwa der Länge 12b des Müllaufnehmers.The front and rear crossbeams 10a, 10b have an identical length which exceeds the width 12a of the garbage collector 12 in such a way that the garbage collector 12 and the longitudinal beams 11 are on both sides there is an approximately equally large game 14 (see FIG. 2). The length of both longitudinal wheels and thus the clear distance between the cross members 10 corresponds approximately to the length 12b of the garbage collector.

Der vordere Abschnitt 4a des Fahrzeugrahmens weist zwei voneinander beabstandete, in Fahrzeuglängsrichtung sich erstreckende vordere Achsenlängsträger 15 auf, die symmetrisch zur Fahrzeuglängsachse 1a angeordnet sind und deren hintere Enden 15a stirnseitig mit dem vorderen Querträger 10a verbunden sind. Auch der hintere Abschnitt 4c des Rahmens weist zwei voneinander beabstandete, in Fahrzeuglängsrichtung sich erstreckende hintere Achsenlängsträger 16 auf, die ebenfalls symmetrisch zur Fahrzeuglängsachse 1a angeordnet sind und deren vordere Enden 16a mit dem hinteren Querträger 10b verbunden sind. Gemäß Fig. 2 weisen die Abstände der vorderen und hinteren Achsenlängsträger 15, 16 voneinander jeweils ein unterschiedliches Maß auf. Bezüglich der vorderen Achsenlängsträger 15 ergibt sich deren lichter Abstand aus der Länge der Querträger 10 vermindert um etwa die zweifache Breite der Fahrzeugräder 5. Die vorderen Enden der vorderen Achsenlängsträger 15 sind mittels eines Frontträgers 17 miteinander verbunden, dessen Länge in etwa dem lichten Abstand der vorderen Achsenlängsträger 15 voneinander entspricht. An der Stirnseite des vorderen Abschnitts 4a des Fahrzeugrahmens ist ferner eine Anbauplatte 18 befestigt, die auch als Stoßstange ausgebildet sein und beispielsweise die Fahrzeugscheinwerfer (nicht-gezeigt) aufnehmen kann.The front section 4a of the vehicle frame has two spaced-apart front axle longitudinal members 15 which extend in the longitudinal direction of the vehicle, which are arranged symmetrically to the longitudinal axle 1a of the vehicle and whose rear ends 15a are connected at the end to the front cross member 10a. The rear section 4c of the frame also has two rear axle longitudinal members 16 which are spaced apart from one another and extend in the vehicle longitudinal direction, which are likewise arranged symmetrically to the vehicle longitudinal axle 1a and whose front ends 16a are connected to the rear cross member 10b. 2, the distances between the front and rear axle side members 15, 16 each have a different dimension. With regard to the front axle side members 15, their clear distance results from the length of the cross members 10 reduced by about twice the width of the vehicle wheels 5. The front ends of the front axle side members 15 are connected to one another by means of a front member 17, the length of which is approximately the clear distance of the front Axle longitudinal beam 15 corresponds to each other. On the front side of the front section 4a of the vehicle frame, a mounting plate 18 is also attached, which can also be designed as a bumper and can accommodate, for example, the vehicle headlights (not shown).

Gemäß den Fig. 1 und 7 bis 9 ist der Fahrzeugrahmen 4 in seinem mittleren Abschnitt 4b, d.h. im Bereich der Öffnung 9, zum Fahrzeugheck 1b geneigt abgewinkelt, so daß der hintere Querträger 10b einen geringeren Bodenabstand als der vordere Querträger 10a aufweist. Dabei ist die Neigung des mittleren Rahmenabschnitts 4b so gewählt, daß die Differenz der Querträger-Bodenabstände in etwa der Höhe 12c des Müllaufnehmers entspricht und der Bodenabstand des hinteren Querträgers 10b mindestens so groß ist wie der Bodenabstand der Hinterachse 3. Die vorderen Enden 16a der hinteren Achsenlängsträger 16 sind zum hinteren Querträger 10b derartig geneigt abgewinkelt, daß der Knickpunkt der Hinterachse 3 vorgeordnet und der dem Knickpunkt nachgeordnete Abschnitt der hinteren Achsenlängsträger 16 in etwa horizontal angeordnet ist.1 and 7 to 9, the vehicle frame 4 is angled at an angle to the rear of the vehicle 1b in its central section 4b, ie in the region of the opening 9, so that the rear cross member 10b has a smaller ground clearance than the front cross member 10a. The inclination of the middle frame section 4b is chosen so that the difference between the cross member-floor distances corresponds approximately to the height 12c of the garbage collector and the floor distance of the rear cross member 10b is at least as large as the floor distance of the rear axle 3. The front ends 16a of the rear Axle side members 16 are angled at an angle to the rear cross member 10b in such a way that the break point is arranged upstream of the rear axle 3 and the section of the rear axle side members 16 downstream of the break point is arranged approximately horizontally.

An der Vorderseite 1c des Nutzfahrzeugs 1 ist eine, z.B. vom Antriebsmotor 6, angetriebene Fahrspurreinigungseinrichtung 20 vorgesehen, die den in der Fahrspur befindlichen Müll zur Fahrzeugmitte 1d hin fördert, so daß der Müll 21 in einen unter dem Nutzfahrzeug 1 befindlichen Mittelstreifen 22 überführt wird. Die Fahrspurreinigungseinrichtung 20 weist gemäß Fig. 2 für jede Fahrspur ein separates Reinigungselement 23 auf, das über einen gemeinsamen Träger 24 an der Vorderseite 1c des Fahrzeugs angebracht ist. Der Träger 24 erstreckt sich in horizontaler Richtung quer zur Fahrtrichtung und weist an seinen Enden Schwenkachsen 24a auf, an denen die Reinigungselemente 23 in vertikaler Richtung schwenkbar gelagert sind. Zwischen dem gemeinsamen Träger 24 und dem Reinigungselement 23 ist eine Betätigungseinrichtung 25 vorgesehen, mit deren Hilfe die Reinigungselemente einzeln oder getrennt voneinander aus einer den Boden 13 berührenden Betriebsstellung in eine vom Boden abgehobene Bereitschaftsstellung und umgekehrt überführbar sind. Insbesondere Fig. 2 zeigt als Rotorschwader 23a ausgebildete Reinigungselemente 23, die jeweils eine vertikale Drehachse 23b aufweisen und gegenläufig angetrieben sind. Dabei weist der in Fahrtrichtung links angeordnete Rotorschwader eine Drehrichtung im Uhrzeigersinn, der in Fahrtrichtung rechts angeordnete Rotorschwader eine dem Uhrzeigersinn entgegengesetzte Drehrichtung auf. Wie genauer aus Fig. 2 und 3 zu ersehen ist, besteht der Rotorschwader 23a aus Kreisschwadrechen, die einen Durchmesser aufweisen, der wenigstens der Fahrspurbreite entspricht.On the front 1c of the commercial vehicle 1, a lane cleaning device 20, for example driven by the drive motor 6, is provided, which conveys the garbage in the lane to the center of the vehicle 1d, so that the garbage 21 is transferred to a median strip 22 located under the commercial vehicle 1. According to FIG. 2, the lane cleaning device 20 has a separate cleaning element 23 for each lane, which is attached to the front 1c of the vehicle via a common carrier 24. The carrier 24 extends transversely to the direction of travel in the horizontal direction and has pivot axes 24a at its ends, on which the cleaning elements 23 are pivotably mounted in the vertical direction. An actuating device 25 is provided between the common carrier 24 and the cleaning element 23, with the aid of which the cleaning elements can be transferred individually or separately from an operating position touching the floor 13 to a standby position raised from the floor and vice versa. 2 shows in particular as rotor rake 23a trained cleaning elements 23, each having a vertical axis of rotation 23b and driven in opposite directions. The rotor swather arranged on the left in the direction of travel has a clockwise direction of rotation, and the rotor swather arranged on the right in the direction of travel has an opposite direction of rotation in the clockwise direction. As can be seen more precisely from FIGS. 2 and 3, the rotor rake 23a consists of circular swath rakes which have a diameter which corresponds at least to the width of the lane.

Zur Abdämpfung von Bodenunebenheiten und zur Einstellung der Eindringtiefe der Kreisschwadrechen in den Boden 13 sind an den Reinigungselementen 23 höhenverstellbare Gleitschuhe 26 befestigt. Diese sind tellerförmig ausgebildet und außerhalb des Arbeitsbereichs der Kreisschwadrechen oder im Bereich der Drehachse 23b angeordnet (s. Fig. 3).In order to dampen uneven floors and to adjust the penetration depth of the circular swath rakes into the floor 13, height-adjustable sliding shoes 26 are attached to the cleaning elements 23. These are plate-shaped and arranged outside the working area of the circular swath rake or in the area of the axis of rotation 23b (see FIG. 3).

Die Kreisschwadrechen sind mit Zinken 23d versehen, die einen entgegen der Drehrichtung weisenden Knick in ihrer Längsachse aufweisen (nicht näher dargestellt). Dadurch sind die Zinken schleppend winklig zum Boden 13 angestellt. Die Zinkenhöhe ist in weiten Grenzen variierbar und beträgt bis zu 0,5m.The circular swath rakes are provided with tines 23d, which have a kink in their longitudinal axis pointing against the direction of rotation (not shown in detail). As a result, the tines are dragging at an angle to the ground 13. The tine height can be varied within wide limits and is up to 0.5m.

Wie in den Fig. 1, 2 und 3 näher gezeigt, sind die Kreisschwadrechen mit Hilfe einer Steuerung, z.B. Kulissensteuerung, von einer den Boden 13 berührenden Betriebsstellung in eine vom Boden abgehobene Bereitschaftsstellung und umgekehrt während eines 360° Umlaufs verschwenkbar. Die Steuerung ist so ausgebildet, daß die gerade im hinteren, d.h. zum Fahrzeug weisenden Teil des Rotorschwaders befindlichen Kreisschwadrechen angehoben sind, während die gerade im vorderen Teil des Rotorschwaders befindlichen Kreisschwadrechen zum Boden hin angestellt sind. Außerdem ist jedes Reinigungselement 23 mit einer Schutzhaube 23e versehen, die auch diffursorähnlich, d.h. mit einem aerodynamischen Förderkanal ausgebildet sein kann (nicht näher dargestellt). Die nach außen gerichtete Öffnung des Förderkanals ist zur Fahrzeugmitte hin ausgerichtet und mündet, möglichst tangential, in den Mittelstreifen 22.As shown in FIGS. 1, 2 and 3 in more detail, the circular swath rakes can be pivoted with the aid of a control, for example a gate control, from an operating position touching the floor 13 to a standby position raised from the floor and vice versa during a 360 ° rotation. The control system is designed so that the circular swath rakes located in the rear part of the rotor swather pointing towards the vehicle are raised, while those in the front part of the Rotor swathers located circular swath rakes are set to the ground. In addition, each cleaning element 23 is provided with a protective hood 23e, which can also be designed like a diffuser, ie with an aerodynamic delivery channel (not shown in more detail). The outward opening of the conveying channel is oriented toward the center of the vehicle and opens, as tangentially as possible, into the median strip 22.

Eine weitere Ausführungsform der Fahrspurreinigungseinrichtung 20 ist in den Fig. 4 bis 6 dargestellt.Another embodiment of the lane cleaning device 20 is shown in FIGS. 4 to 6.

Gemäß dieser Ausführungsform ist die Fahrspurreinigungseinrichtung 20 als gegenläufig gewendelte Schnecke 27 mit einer horizontal und quer zur Fahrzeugslängsrichtung verlaufenden Schneckenachse 27a ausgebildet. Dabei ist es möglich, die Schnecke über die gesamte Fahrzeugbreite auszubilden und mit gegenläufigen Wendeln zu versehen, oder in jeder Fahrspur eine separate Wendel (s. Fig. 4) vorzusehen, die den Müll von der Fahrspuraußenseite in den unter dem Fahrzeug befindlichen Mittelstreifen befördert. Zur Erreichung dieses Zwecks ist die Drehrichtung der Schnecke entsprechend auszuwählen. Gemäß Fig. 5 ist die Schnecke 27 dem Fahrzeugrad 5 unmittelbar vorgeordnet und zwecks einer gezielten Förderung des Mülls mit einer Schutzhaube 27b versehen. Zur Erhöhung der Förderkapazität weist ein auf der Schnecke umlaufender Schneckenkamm 27c Zinken 27d auf, die mit Hilfe einer nicht-dargestellten Steuereinrichtung in ihrer Längsrichtung oder quer dazu aus einer Betriebs- in eine Bereitschaftsstellung und umgekehrt während eines 360° Umlaufs verstellbar sind. Die Steuereinrichtung ist so ausgebildet, daß die Zinken 27d in dem nach oben weisenden Abschnitt der Schnecke 27 zur Schneckenachse 27a hin zurückgezogen sind, während sie in der zum Boden weisenden Schneckenhälfte in Richtung auf den Boden 13 und in Richtung des zu fördernden Mülls radial nach außen verschoben sind. In der unteren, zum Boden 13 weisenden Schneckenhälfte findet deshalb zunächst eine radial nach außen gerichtete Bewegung (s. Pfeil A in Fig. 5 und 6) und schließlich nach Durchfahren des unteren Totpunkts eine zur Schneckenachse 27a, d.h. nach innen gerichtete, Bewegung (s. Pfeil B in Fig. 5 und 6) der Zinken 27d statt. Auch im Fall der Ausbildung der Fahrspurreinigungseinrichtung als Schnecke kann eine Betätigungsvorrichtung vorgesehen sein, mit deren Hilfe der Abstand der Schnecke 27 vom Boden 13 bzw. deren Eindringtiefe in den Boden eingestellt und variiert werden kann. Die Fahrspurreinigungseinrichtung 20 kann ferner in Form einer Bürstenrolle mit vertikaler und/oder horizontaler Drehachse ausgebildete sein.According to this embodiment, the lane cleaning device 20 is designed as an oppositely coiled worm 27 with a worm axis 27a running horizontally and transversely to the longitudinal direction of the vehicle. It is possible to design the auger over the entire width of the vehicle and to provide it with opposing coils, or to provide a separate coil in each lane (see FIG. 4) which conveys the garbage from the outside of the lane to the median strip located under the vehicle. To achieve this purpose, the direction of rotation of the screw must be selected accordingly. According to FIG. 5, the worm 27 is arranged directly upstream of the vehicle wheel 5 and is provided with a protective hood 27b for the purpose of specifically promoting the waste. In order to increase the conveying capacity, a screw comb 27c running on the screw has tines 27d, which can be adjusted with the help of a control device (not shown) in its longitudinal direction or transversely thereto from an operating position to a standby position and vice versa during a 360 ° rotation. The control device is like this formed that the tines 27d are retracted in the upward-pointing section of the screw 27 towards the screw axis 27a, while they are displaced radially outwards in the screw half facing the bottom in the direction of the bottom 13 and in the direction of the waste to be conveyed. In the lower half of the screw facing the bottom 13 there is therefore first a radially outward movement (see arrow A in FIGS. 5 and 6) and finally after passing through the bottom dead center there is a movement towards the screw axis 27a, ie inwards, movement (see Arrow B in FIGS. 5 and 6) of the prongs 27d instead. Even if the lane cleaning device is designed as a screw, an actuating device can be provided, with the aid of which the distance of the screw 27 from the floor 13 or its depth of penetration into the floor can be adjusted and varied. The lane cleaning device 20 can also be designed in the form of a brush roller with a vertical and / or horizontal axis of rotation.

Wie in Fig. 2 dargestellt, ist zwischen den Reinigungselementen 23 ein teilweise gebrochen dargestelltes Prall- oder Ablegeblech 30 angeordnet. Das Prallblech kann so ausgeformt sein, daß es einen in der Fahrzeugslängsachse 1a sich erstreckenden Teil 30a aufweist und zu den Reinigungselementen 23 hin tangential ausläuft. Der zu den Reinigungselementen 23 weisende Teil kann auch in die Schutzhaube 23e der Reinigungselemente auslaufen oder selbst als Schutzhaube fungieren.As shown in FIG. 2, a baffle or deposit plate 30, shown partially broken, is arranged between the cleaning elements 23. The baffle plate can be shaped in such a way that it has a part 30a which extends in the longitudinal axis 1a of the vehicle and runs out tangentially towards the cleaning elements 23. The part facing the cleaning elements 23 can also run out into the protective hood 23e of the cleaning elements or itself function as a protective hood.

Nachfolgend wird unter Bezug auf die Fig. 1, 2 und 7 der Müllaufnehmer 12 näher erläutert. Die Breite 12a (s.Fig. 2) des Müllaufnehmers sollte wenigstens der Breite des Mittelstreifens 22 entsprechen, um eine ordnungsgemäße Müllaufnahme zu ermöglichen. Der Müllaufnehmer besteht im wesentlichen aus einer Aufnahmekeilleiste 31 und einem um zwei Umlenkachsen 32a, b geführten und der Aufnahmekeilleiste 31 nachgeordneten Elevator 32. Die Aufnahmekeilleiste 31 besteht aus voneinander beabstandeten, nahezu dreieckig ausgebildeten Aufnahmeelementen 31a (siehe Fig. 2), die auch zahnförmig und/oder tangential zum Boden 13 weisend ausgebildet sein können.The waste pick-up 12 is explained in more detail below with reference to FIGS. 1, 2 and 7. The width 12a (see Fig. 2) of the garbage collector should at least correspond to the width of the central strip 22 in order to ensure a proper To allow waste collection. The garbage collector essentially consists of a receiving wedge strip 31 and an elevator 32 which is guided around two deflection axes 32a, b and is arranged downstream of the receiving wedge strip 31. The receiving wedge strip 31 consists of receiving elements 31a (see FIG. 2) which are spaced apart from one another and are almost triangular and also tooth-shaped and / or can be formed pointing tangentially to the floor 13.

In der Betriebsstellung des Müllaufnehmers 12 (siehe Fig. 1) wird die Aufnahmekeilleiste 31 in der Nähe des Bodens 13 gehalten oder mit einer bestimmten Eindringtiefe durch den Boden, z.B. Sand, geführt. Die Eindringtiefe der Aufnahmekeilleiste 31 beträgt mehrere cm, vorzugsweise etwa 5cm. In der Betriebsstellung ist deshalb die vordere Umlenkachse 32a bodennah und die hintere Umlenkachse 32b bodenfern angeordnet, wobei letztere über dem hinteren Querträger 10b und/oder über der Hinterachse 3 des Fahrzeugs angeordnet ist.In the operating position of the garbage collector 12 (see Fig. 1), the receiving wedge strip 31 is held near the bottom 13 or with a certain depth of penetration through the bottom, e.g. Sand, led. The depth of penetration of the receiving wedge strip 31 is several cm, preferably about 5 cm. In the operating position, therefore, the front deflection axis 32a is arranged close to the ground and the rear deflection axis 32b is arranged away from the ground, the latter being arranged above the rear cross member 10b and / or above the rear axle 3 of the vehicle.

Der Elevator 32 weist einen jeweils zwischen den Umlenkachsen 32a, 32b sich erstreckenden Ober- und Untertrum auf, wobei die Drehrichtung der Umlenkachsen so gewählt ist, daß der obere Trum nach hinten und der untere Trum nach vorne läuft. Die Drehrichtung des Elevators 32 in Fig. 1 entspricht also dem Uhrzeigersinn. Der Elevator 32 kann in Abhängigkeit von dem aufzunehmenden Müll sehr unterschiedlich, vorzugsweise als Förderband, Kratzboden, Rechen- oder Gliederband, gestaltet sein. Außerdem kann das umlaufende Trum eine Oberflächenbeschichtung oder speziell ausgestaltete Greifer aufweisen, die ein sicheres Greifen, Aufnehmen und Befördern des Mülls gestatten. Wenigstens eine der Umlenkachsen, vorzugsweise die obere Umlenkachse 32b, ist als Antriebsachse ausgebildet und über den Antriebsmotor 6 oder einen separat vorgesehenen Motor angetrieben.The elevator 32 has an upper and lower run extending between the deflection axes 32a, 32b, the direction of rotation of the deflection axes being selected such that the upper run runs to the rear and the lower run runs to the front. The direction of rotation of the elevator 32 in FIG. 1 thus corresponds to the clockwise direction. Depending on the garbage to be picked up, the elevator 32 can be designed very differently, preferably as a conveyor belt, scraper floor, rake or link belt. In addition, the circumferential strand can have a surface coating or a specially designed gripper that a allow safe gripping, picking up and transporting of the garbage. At least one of the deflection axes, preferably the upper deflection axis 32b, is designed as a drive axis and is driven via the drive motor 6 or a separately provided motor.

Die seitlichen Enden der oberen Umlenkachse 32b sind in einen jeweils auf dem Längsträger 11 abgestützten Tragarm 33 drehbar gelagert. Zwischen dem Fahrzeugrahmen 4 und dem oberen Ende des Müllaufnehmers 12 ist ein Stellantrieb 34, z.B. eine Kolben-Zylinder-Einheit, vorgesehen, die einenends mit dem mittleren Abschnitt 4b des Rahmens, andernends mit einem an dem oberen Ende des Müllaufnehmers befestigten Schwenkarm 35 lösbar verbunden ist. Durch ein Betätigen des Stellantriebs ist ein Verschwenken des Müllaufnehmers 12 in der Öffnung 9, d.h. ein Regulieren der Arbeitstiefe ebenso wie ein Überführen des Müllaufnehmers aus der Bereitschafts- in die Betriebsstellung und umgekehrt möglich. Dabei wird der Müllaufnehmer um die in dem Tragarm 33 gehaltene Umlenkachse 32b verschwenkt. Daraus ergibt sich, daß die obere Umlenkachse 32b ortsfest gehalten ist, während die Lage der Umlenkachse 32a zwischen dem Boden 13 und etwa dem Bodenabstand des vorderen Querträgers 10a variierbar ist.The lateral ends of the upper deflection axis 32b are rotatably mounted in a respective support arm 33 supported on the longitudinal beam 11. Between the vehicle frame 4 and the upper end of the garbage collector 12 there is an actuator 34, e.g. a piston-cylinder unit is provided, one end of which is detachably connected to the central section 4b of the frame, and the other end to a pivot arm 35 attached to the upper end of the garbage collector. By actuating the actuator, the garbage collector 12 can be pivoted in the opening 9, i.e. a regulation of the working depth as well as a transfer of the waste pick-up from the standby into the operating position and vice versa possible. The garbage collector is pivoted about the deflection axis 32b held in the support arm 33. It follows from this that the upper deflection axis 32b is held stationary, while the position of the deflection axis 32a can be varied between the floor 13 and approximately the floor distance of the front cross member 10a.

Im Anschluß an den Müllaufnehmer 12 ist eine Fördereinrichtung 36 vorgesehen, die den vom Müllaufnehmer 12 abgegebenen Müll an einen am Fahrzeugheck 1b angebrachten Sammelbehälter 37 überführt. Die Fördereinrichtung 36 weist in ihrem vorderen Teil eine Anschlagleiste 36 a (siehe Fig. 1) auf, die auch als Abstreifer zum Lösen des auf dem Elevator 32 befindlichen Mülls ausgebildet sein kann. Die Fördereinrichtung 36 ist mittels eines Motors antreibbar und vorzugsweise als horizontales oder nach hinten ansteigendes Rüttelsieb 36b oder als horizontales Förderband ausgestaltet. Das Rüttelsieb 36b ist elastisch am hinteren Abschnitt 4c des Rahmens oder nahe der Hinterachse 3 aufgehängt und mit Hilfe eines Exzenterantriebs, z.B. eines Hydrostatantriebs, in Bewegung versetzt. Das Förderband ist herkömmlicherweise mit zwei Umlenkachsen versehen, von denen wenigstens eine angetrieben ist. Um ein Herabrollen des Mülls von dem Müllaufnehmer 12 und der Fördereinrichtung 36 zu verhindern, können diese mit seitlichen Auffangblechen (nicht gezeigt) versehen sein.Following the garbage collector 12, a conveyor 36 is provided which transfers the garbage discharged from the garbage collector 12 to a collecting container 37 attached to the rear of the vehicle 1b. The conveyor 36 has in its front part a stop bar 36 a (see FIG. 1), which can also be designed as a scraper for loosening the garbage on the elevator 32. The conveyor 36 is by means of a motor drivable and preferably designed as a horizontal or backward rising vibrating screen 36b or as a horizontal conveyor belt. The vibrating screen 36b is elastically suspended on the rear section 4c of the frame or near the rear axle 3 and is set in motion with the aid of an eccentric drive, for example a hydrostatic drive. The conveyor belt is conventionally provided with two deflection axes, at least one of which is driven. In order to prevent the garbage from rolling down from the garbage collector 12 and the conveyor device 36, these can be provided with side collecting plates (not shown).

Am Ende des Rüttelsiebs 36b ist eine Übergabeleiste 36c aus Gummi vorgesehen, mit deren Hilfe der Müll in den Sammelbehälter 37 eingeleitet wird.At the end of the vibrating screen 36b, a transfer bar 36c made of rubber is provided, with the aid of which the waste is introduced into the collecting container 37.

Zwischen der Fördereinrichtung 36 und der Hinterachse 3 ist ein Prallblech 38 angeordnet, das im Fördersinn des Rüttelsiebs 36b mitbewegt sein kann (s. Fig. 1).A baffle plate 38 is arranged between the conveyor device 36 and the rear axle 3 and can be moved in the direction of conveyance of the vibrating screen 36b (see FIG. 1).

Der Sammelbehälter 37 ist mit Hilfe zweier seitlicher Lenker 40 am Fahrzeugrahmen 4 oder an der Ladefläche 8 gehalten. In den Fig. 1, 2, 7 bis 9 ist jeder Lenker 40 einenends über eine horizontale Schwenkachse 41 an der Ladefläche 8 und andernends ebenfalls über eine horizontale Schwenkachse 42 an dem Sammelbehälter 37 drehbar gelagert. Jedem Lenker 40 ist ein Stellantrieb 43, z.B. eine Kolben-Zylinder-Einheit, zugeordnet, deren eines Ende lösbar mit einer Seitenwand der Ladefläche 8 und dessen anderes Ende mit einem jeweils an den Lenkern 40 befestigten Schwenkwarm 40a lösbar gehalten ist. Der Sammelbehälter 37 ist vorzugsweise als Kippmulde ausgebildet, wobei die Schwenkachsen 42 dem Schwerpunkt des Sammelbehälters 37 vorgeordnet sind.The collecting container 37 is held on the vehicle frame 4 or on the loading surface 8 with the aid of two lateral links 40. 1, 2, 7 to 9, each link 40 is rotatably supported at one end via a horizontal pivot axis 41 on the loading surface 8 and at the other end likewise via a horizontal pivot axis 42 on the collecting container 37. Each link 40 is assigned an actuator 43, for example a piston-cylinder unit, one end of which is detachably held by a side wall of the loading surface 8 and the other end of which is detachably held by a pivoting arm 40a attached to the links 40. The collecting container 37 is preferably designed as a tipping trough, the pivot axes 42 being arranged upstream of the center of gravity of the collecting container 37.

Unterhalb und in Höhe der Schwenkachsen 42 sind an Seitenwänden des Sammelbehälters jeweils Anschläge 44, 45 vorgesehen, die den Schwenkweg des der Schwenkachse 42 nachgeordneten hinteren Endes jedes Lenkers begrenzen. Bei einem Betätigen des Stellantriebs 43 und einer kreisförmigen aufwärtsgerichteten Schwenkbewegung der Lenker 40 sowie des Sammelbehälters 37 um die Schwenkachse 41 wirkt das hintere Ende der Lenker 40 schließlich mit dem Anschlag 44 zusammen.Above and at the level of the pivot axes 42, stops 44, 45 are provided on the side walls of the collecting container, which limit the pivoting path of the rear end of the pivot axis 42 downstream. When the actuator 43 is actuated and the arm 40 and the collecting container 37 are pivoted in a circular upward movement about the pivot axis 41, the rear end of the arm 40 finally interacts with the stop 44.

Aufgrund der exzentrischen Lagerung entleert sich der Sammelbehälter automatisch durch Umkippen über der Ladefläche 8 (Fig. 7).Due to the eccentric storage, the collection container is automatically emptied by tipping over the loading area 8 (FIG. 7).

Außerdem kann zwischen den seitlichen Lenkern 40 und dem Sammelbehälter 37 ein weiterer Stellantrieb vorgesehen sein, der ein Kippen des Sammelbehälters 37 unabhängig von einem Verschwenken der Lenker gestattet. Damit ist ein Entleeren des Sammelbehälters auch in der in Fig. 1 gezeigten Stellung möglich. Bei dieser Ausführungsform ist die Rückwand 37a des Sammelbehälters derartig geneigt, daß Rückwand 37a und Boden 13 in einer nach hinten offenen Müllaufnahmestellung des Sammelbehälters in etwa parallel zueinander angeordnet sind. Außerdem weist der Sammelbehälter eine Füllstandsanzeige auf, die mit einer in der Fahrerkabine 7 angeordneten Anzeigevorrichtung (nicht gezeigt) zusammenwirkt und den Fahrer auf einen gefüllten Sammelbehälters hinweist.In addition, a further actuator can be provided between the lateral links 40 and the collection container 37, which allows the collection container 37 to be tilted independently of a pivoting of the handlebars. Emptying of the collecting container is thus also possible in the position shown in FIG. 1. In this embodiment, the rear wall 37a of the collecting container is inclined in such a way that the rear wall 37a and bottom 13 are arranged approximately parallel to one another in a garbage receiving position of the collecting container which is open towards the rear. In addition, the collecting container has a fill level indicator which interacts with a display device (not shown) arranged in the driver's cab 7 and which informs the driver of a filled collecting container.

Am Heck des Sammelbehälters 37 ist gemäß Fig. 1 ein auf dem Boden 13 aufliegender Finisher 46 mittels einer an dem Sammelbehälter befestigten Halteplatte 47 schwenkbar angelenkt. Der Finisher kann aber auch an einem anderen Teil des Fahrzeugs, insbesondere den Hinterrädern nachgeordnet, vorzugsweise am Fahrzeugrahmen 4, angebracht sein. Zum Verstellen der Neigung bzw. zum Regulieren der Eindringtiefe des Finishers ist zwischen dem Sammelbehälter 37 und dem Finisher 46 ein Stellantrieb 48, z.B. eine Kolben-Zylinders-Einheit, angebracht (in Fig. 1 nur schematisch angedeutet).1, a finisher 46 resting on the floor 13 is pivotably articulated by means of a holding plate 47 fastened to the collecting container at the rear of the collecting container 37. The finisher can also on another part of the vehicle, especially the rear wheels arranged downstream, preferably on the vehicle frame 4. To adjust the inclination or to regulate the depth of penetration of the finisher, an actuator 48, for example a piston-cylinder unit, is attached between the collecting container 37 and the finisher 46 (only indicated schematically in FIG. 1).

Wie im einzelnen in den Fig. 1 und 7 bis 9 gezeigt, ist die Ladefläche 8 hinter der Fahrerkabine 7 und über der Hinterachse 3 angeordnet und erstreckt sich nahezu vollständig über dem Müllaufnehmer 12 und der Fördereinrichtung 36. Die Ladefläche ist rechteckig ausgebildet und besteht im wesentlichen aus einer Bodenwand 8a, zwei in Fahrzeuglängsrichtung sich erstreckenden Seitenwänden 8b, einer Vorderwand 8c und einer verstellbaren Hinterwand 8d, die auch als Schüttvorrichtung ausgebildet sein kann. Die Ladefläche 8 ist mit Hilfe eines Stellantriebs 49 um eine am hinteren Ende der hinteren Achsenlängsträger 16 befindlichen Schenkachse 50 kippbar. Der Stellantrieb 49 zum Kippen der Ladefläche 8 ist an dem vorderen Querträger 10a und an der Unterseite der Bodenwand 8a abgestützt. An der Unterseite der Bodenwand 8a sind hintere Radabdeckungen 51 für die Hinterräder, an der Fahrerkabine 7 oder an dem vorderen Abschnitt 4a des Fahrzeugrahmens sind vordere Radabdeckungen 52 für die Vorderräder angebracht.As shown in detail in FIGS. 1 and 7 to 9, the loading area 8 is arranged behind the driver's cab 7 and above the rear axle 3 and extends almost completely over the garbage collector 12 and the conveyor 36. The loading area is rectangular and consists of essentially from a bottom wall 8a, two side walls 8b extending in the vehicle longitudinal direction, a front wall 8c and an adjustable rear wall 8d, which can also be designed as a pouring device. The loading area 8 can be tilted by means of an actuator 49 about a pivot axis 50 located at the rear end of the rear axle longitudinal member 16. The actuator 49 for tilting the loading area 8 is supported on the front cross member 10a and on the underside of the bottom wall 8a. On the underside of the bottom wall 8a there are rear wheel covers 51 for the rear wheels, on the driver's cab 7 or on the front section 4a of the vehicle frame there are front wheel covers 52 for the front wheels.

In Fig. 8 ist das Nutzfahrzeug mit betätigtem Stellantrieb 49 und gekippter Ladefläche 8 dargestellt, wobei die Reinigungselmente 23 und der Müllaufnehmer 12 in der vom Boden 13 abgehobenen Bereitschaftsstellung angeordnet sind. Zum Entleeren der Ladefläche 8 befindet sich der Sammelbehälter 37 infolge eines Betätigens des Stellantriebs 43 in der vom Boden weg zur Ladefläche geschwenkten Kippstellung.8 shows the commercial vehicle with actuated actuator 49 and tilted loading area 8, the cleaning elements 23 and the garbage collector 12 being arranged in the ready position lifted off the floor 13. For emptying the loading area 8, the collecting container 37 is located in the area away from the floor towards the loading area due to an actuation of the actuator 43 pivoted tilt position.

Fig. 9 zeigt das Nutzfahrzeug 1 mit demontierter Fahrspurreinigungseinrichtung 20 und demontiertem Müllaufnehmer 12. Es ist ferner möglich, das Nutzfahrzeug so auszubilden, daß auch die Fördereinrichtung 36 vom Fahrzeug lösbar ist.
