Definitions
- the invention relates to a spreading vehicle with a spreading device built on a loading platform, in particular a silo spreading device, in which the spreading material is automatically removed from a silo container and fed via a discharge channel to a spreading plate arranged at the rear, which is attached to the discharge channel.
- the problem arises that with increasing emptying of the loading platform or the silo container, the deflection of the vehicle frame with respect to the wheel axles becomes smaller, so that the spreading plate assumes an increasingly distant position from the ground in accordance with the relief of the vehicle.
- the spreading material thrown off the spreading plate only appears on the ground at a greater distance from the spreading plate.
- the value is e.g. 3 m - this means at least on narrow roads that with increasing relief of the spreading vehicle, vehicles parked on the side are hit by the spreading material.
- the driver has no way of avoiding this disadvantage, since he cannot be expected to continuously readjust the spreading device under the conditions of road traffic.
- the present invention has for its object to provide a gritting vehicle of the generic type to be equipped in such a way that the spread can be kept approximately constant during operation.
- this object is achieved by an automatically operating device which keeps the throwing distance of the spreading material thrown by the spreading disc essentially constant regardless of the loading of the spreading vehicle or the filling of the silo container.
- the device is a measuring device for measuring the distance between the spreading device and the ground or the wheel axis of the spreading vehicle and in the other case a measuring device for measuring the loading of the vehicle or the filling of the Contains silo.
- Both solutions ensure an automatic adjustment of the dropping conditions from the spreading disc, such that an approximately constant spreading width can be maintained regardless of the change in the loading of the spreading vehicle.
- the spreading disc is used with increasing relief of the of the gritting vehicle increasingly approaching the ground, ie lowered relative to the vehicle axles. This lowering movement compensates for the increasing rebound of the vehicle.
- the spreading width is kept constant in spite of the increasing spreading plate being raised relative to the ground in that the speed of the spreading plate decreases accordingly, the centrifugal forces acting on the spreading material being reduced.
- Another essential requirement of the teaching according to the invention is the ongoing and automatic determination of a measurement variable proportional to the increasing emptying of the grit container, preferably the distance between the grit plate and the ground or grit plate and the vehicle axle.
- a control signal is generated via a control device, to the input of which the measurement signal is connected, with which a control variable, preferably either the speed or the altitude of the spreading disc, is changed in the sense of a reduction.
- the distance measurement can be carried out in the context of the invention by means of a measuring device which either works with a mechanical probe or without contact, for example by means of ultrasound, echo sounder, laser beam or the like.
- the ongoing measurement of the loading or unloading state of the silo container can e.g. by more or less deeply immersed in the grit, by measuring the vibration amplitudes of the loading platform or - particularly simply - by counting the number of revolutions of the screw conveyor, taking into account the initial filling level of the silo container.
- the invention achieves a constant spreading density, ie it is ensured that the spreading density does not decrease with increasing emptying of the spreading material container. Increasing the spreading plate and the associated increase in the spreading width with a constant supply quantity would otherwise result in an increase in the spreading area and thus a decrease in the spreading density per m2.
- the constant spreading width achieved according to the invention is a very significant advantage under the current spreading requirements because it opens up the possibility of setting the spreading density to a minimum without fear of it being undershot.
- Fig. 1 two alternative measuring devices are each shown schematically, with which an output signal corresponding to the spring deflection of the loading platform (1) is generated, which is converted into a control signal for adjusting the length of the telescopic holder (7) by means of a control device (not shown).
- a first alternative for measuring the platform height is an electronic measuring device (10) which measures the distance from the floor (9), for example by means of a laser beam (11).
- a second alternative is a mechanical measuring device (12) which measures the change in distance between the loading platform (1) and the vehicle axle (2) by means of a feeler lever (13) which is articulated on the differential housing (14).
- both types of measuring devices require damping or smoothing in such a way that vibrations of the vehicle body due to bumps on uneven road surfaces are suppressed.
- the normal discharge height of the spreading plate (6) is set at about 30 cm when the silo container (3) is fully loaded, it can increase in operation with its increasing discharge without the device according to the invention by about 15 to 20 cm come. In the horizontal direction, this means an undesired increase in the originally set maximum spreading width from approx. 3 m to approx. 4 m.
- the device according to the invention succeeds in keeping the spreading disc (6) unchanged in its initially set height above the ground during the entire spreading operation.
- the set height depends on the desired spreading distance of the spreading material. This is a function not only of the height of the spreading disc above the ground but also of the speed of the spreading disc.

Abstract
Description
Die Erfindung betrifft ein Streufahrzeug mit auf einer Ladepritsche aufgebautem Streugerät, insbesondere Silostreugerät, bei welchem das Streugut einem Silobehälter automatisch entnommen und über eine Auslaufrinne einem heckseitig angeordneten Streuteller zugeführt wird, welcher an der Auslaufrinne befestigt ist.The invention relates to a spreading vehicle with a spreading device built on a loading platform, in particular a silo spreading device, in which the spreading material is automatically removed from a silo container and fed via a discharge channel to a spreading plate arranged at the rear, which is attached to the discharge channel.
Bei derartigen Streufahrzeugen tritt das Problem auf, daß mit zunehmender Entleerung der Ladepritsche bzw. des Silobehälters die Einfederung des Fahrzeugrahmens bezogen auf die Radachsen geringer wird, sodaß der Streuteller entsprechend der Entlastung des Fahrzeugs eine vom Boden zunehmend entferntere Position einnimmt. Dies hat zur Folge, daß das vom Streuteller abgeschleuderte Streugut erst mit größerer Entfernung vom Streuteller auf den Boden auftritt. Bei vorgegebener maximaler Streubreite - deren Wert beträgt z.B. 3 m - bedeutet dies zumindest bei engen Straßen, daß mit zunehmender Entlastung des Streufahrzeugs seitlich parkende Fahrzeuge vom Streugut getroffen werden. Bei den bislang bekannten Streufahrzeugen hat der Fahrer keine Möglichkeit, diesen Nachteil zu vermeiden, da ihm eine laufende Nachregulierung des Streugeräts unter den Bedingungen des Straßenverkehrs nicht zugemutet werden kann.In such spreading vehicles, the problem arises that with increasing emptying of the loading platform or the silo container, the deflection of the vehicle frame with respect to the wheel axles becomes smaller, so that the spreading plate assumes an increasingly distant position from the ground in accordance with the relief of the vehicle. The result of this is that the spreading material thrown off the spreading plate only appears on the ground at a greater distance from the spreading plate. Given the maximum spread, the value is e.g. 3 m - this means at least on narrow roads that with increasing relief of the spreading vehicle, vehicles parked on the side are hit by the spreading material. In the previously known spreading vehicles, the driver has no way of avoiding this disadvantage, since he cannot be expected to continuously readjust the spreading device under the conditions of road traffic.
Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Streufahrzeug der gattungsgemäßen Art so auszurüsten, daß die Streubreite im Betrieb etwa konstant gehalten werden kann.In contrast, the present invention has for its object to provide a gritting vehicle of the generic type to be equipped in such a way that the spread can be kept approximately constant during operation.
Erfindungsgemäß wird diese Aufgabe durch eine automatisch arbeitende Einrichtung gelöst, welche die Wurfweite des vom Streuteller abgeschleuderten Streuguts unabhängig von der Beladung des Streufahrzeugs bzw. der Füllung des Silobehälters im wesentlichen konstant hält.According to the invention, this object is achieved by an automatically operating device which keeps the throwing distance of the spreading material thrown by the spreading disc essentially constant regardless of the loading of the spreading vehicle or the filling of the silo container.
Im Rahmen dieses Erfindungsgedankens sind zwei alternative Lösungswege denkbar, wobei in dem einen Fall die Einrichtung ein Meßgerät zum Messen des Abstandes zwischen Streugerät und Boden oder der Radachse des Streufahrzeugs und in dem anderen Fall ein Meßgerät zum Messen der Beladung der Fahrzeugs bzw. der Füllung des Silobehälters umfaßt.Within the scope of this inventive idea, two alternative solutions are conceivable, in which case the device is a measuring device for measuring the distance between the spreading device and the ground or the wheel axis of the spreading vehicle and in the other case a measuring device for measuring the loading of the vehicle or the filling of the Contains silo.
Beide Lösungswege gewährleisten eine automatische Anpassung der Abwurfbedingungen vom Streuteller, derart, daß unabhängig von der Änderung der Beladung des Streufahrzeugs eine etwa konstante Streubreite aufrecht erhalten werden kann. Dabei besteht wahlweise die Möglichkeit einer Regelung durch Reduzierung entweder der Höhe des Streutellers über den Boden oder von dessen Drehzahl. Bei der erstgenannten Alternative wird der Streuteller mit zunehmender Entlastung des des Streufahrzeugs zunehmend dem Boden angenähert, d.h. relativ zu den Fahrzeugachsen abgesenkt. Durch diese Absenkbewegung wird das zunehmende Ausfedern des Fahrzeugs ausgeglichen.
Bei der zweitgenannten Alternative wird trotz zunehmender Anhebung des Streutellers gegenüber dem Boden die Streubreite dadurch konstant gehalten, daß die Drehzahl des Streutellers entsprechend abnimmt, wobei die auf das Streugut wirkenden Fliehkräfte reduziert werden.Both solutions ensure an automatic adjustment of the dropping conditions from the spreading disc, such that an approximately constant spreading width can be maintained regardless of the change in the loading of the spreading vehicle. There is either the option of regulation by reducing either the height of the spreading disc above the ground or its speed. In the first alternative, the spreading disc is used with increasing relief of the of the gritting vehicle increasingly approaching the ground, ie lowered relative to the vehicle axles. This lowering movement compensates for the increasing rebound of the vehicle.
In the second alternative, the spreading width is kept constant in spite of the increasing spreading plate being raised relative to the ground in that the speed of the spreading plate decreases accordingly, the centrifugal forces acting on the spreading material being reduced.
Eine weitere wesentliche Voraussetzung der erfindungsgemäßen Lehre ist das laufende und automatische Bestimmen einer zur zunehmenden Entleerung des Streugutbehälters proportionalen Meßgröße, bevorzugt des Abstandes zwischen Streuteller und Boden bzw. Streuteller und Fahrzeugachse. Mit der ermittelten Meßgröße wird über ein Regelgerät, an dessen Eingang das Meßsignal angeschlossen ist, ein Stellsignal erzeugt, mit welchem eine Stellgröße, bevorzugt entweder die Drehzahl oder die Höhenlage des Streutellers, im Sinne einer Reduzierung verändert wird.Another essential requirement of the teaching according to the invention is the ongoing and automatic determination of a measurement variable proportional to the increasing emptying of the grit container, preferably the distance between the grit plate and the ground or grit plate and the vehicle axle. With the measured variable determined, a control signal is generated via a control device, to the input of which the measurement signal is connected, with which a control variable, preferably either the speed or the altitude of the spreading disc, is changed in the sense of a reduction.
Die Abstandsmessung kann in Rahmen der Erfindung mittels eines Meßgeräts erfolgen, welches entweder mit einem mechanischen Tastorgan oder berührungsfrei, z.B. mittels Ultraschall, Echolot, Laserstrahl oder dergleichen arbeitet.The distance measurement can be carried out in the context of the invention by means of a measuring device which either works with a mechanical probe or without contact, for example by means of ultrasound, echo sounder, laser beam or the like.
Die laufende Messung des Be- bzw. Entladungszustands des Silobehälters kann z.B. durch mehr- oder weniger tief in das Streugut eintauchende Sensoren, durch Messen der Schwingungsamplituden der Ladepritsche oder - besonders einfach - durch Zählen der Anzahl der Umdrehungen der Förderschnecke unter Berücksichtigung des anfänglichen Befüllungsgrads des Silobehälters erfolgen.The ongoing measurement of the loading or unloading state of the silo container can e.g. by more or less deeply immersed in the grit, by measuring the vibration amplitudes of the loading platform or - particularly simply - by counting the number of revolutions of the screw conveyor, taking into account the initial filling level of the silo container.
Gleichzeitig mit der Konstanthaltung der Streubreite erreicht die Erfindung eine konstante Streudichte, d.h. es wird sichergestellt, daß die Streudichte mit zunehmender Entleerung des Streugutbehälters nicht etwa abnimmt. Das Höherwerden des Streutellers und die damit verbundene Vergrößerung der Streubreite bei konstanter Zuführmenge ergibt nämlich andernfalls eine Vergrößerung der bestreuten Fläche und dadurch eine Verringerung der Streudichte pro m². Die erfindungsgemäß erzielte Konstanthaltung der Streubreite ist unter den aktuellen Streuanforderungen ein sehr wesentlicher Vorteil, weil damit die Möglichkeit eröffnet wird, die Streudichte auf ein Minimum einzustellen, ohne daß dessen Unterschreitung befürchtet werden muß.At the same time that the spreading width is kept constant, the invention achieves a constant spreading density, ie it is ensured that the spreading density does not decrease with increasing emptying of the spreading material container. Increasing the spreading plate and the associated increase in the spreading width with a constant supply quantity would otherwise result in an increase in the spreading area and thus a decrease in the spreading density per m². The constant spreading width achieved according to the invention is a very significant advantage under the current spreading requirements because it opens up the possibility of setting the spreading density to a minimum without fear of it being undershot.
Im folgendem wird die Erfindung anhand der Zeichnung beschrieben. Es zeigt
- Fig. 1 eine Seitenansicht des Hecks eines Streufahrzeugs und
- Fig. 2 eine Rückansicht des Streufahrzeugs
- Fig. 1 is a side view of the rear of a gritter and
- Fig. 2 is a rear view of the gritter
In Fig. 1 und 2 ist von einem Streufahrzeug lediglich der rückwärtige Teil mit der Ladepritsche (1) und der hinteren Fahrzeugachse (2) dargestellt. Auf der Ladepritsche (1) befindet sich ein Silobehälter (3) für das Streugut. Dieses gelangt über eine Auslaufrinne (4) und eine Zuführrutsche (5) auf den Streuteller (6). Der Streuteller (6) ist an der Auslaufrinne (4) mittels eines teleskopisch verlängerbaren Halters (7) befestigt. Zur Höhenverstellung des Streutellers (6) dient ein von einer nicht gezeichneten Regeleinrichtung ansteuerbarer Hydraulikzylinder (8). Bei dessen Betätigung wird der Halter (7) in seiner Ausfahrlänge auf eine bestimmte Beladung eingestellt bzw. während des Betriebes des Streufahrzeugs wird der Halter (7) durch den Hydraulikzylinder (8) zunehmend verlängert. Die Verlängerung erfolgt proportional dem Ausfedern der Ladepritsche (1) infolge zunehmender Entleerung des Silobehälters (3). Durch Verlängern des Halters (7) wird der Streuteller (6) stets in etwa gleicher Höhe über dem Boden (9) eingestellt.1 and 2 of a spreader vehicle, only the rear part with the loading platform (1) and the rear vehicle axle (2) is shown. There is a silo container (3) for the spreading material on the loading platform (1). This reaches the spreading plate (6) via an outlet chute (4) and a feed chute (5). The spreader plate (6) is attached to the outlet channel (4) by means of a telescopically extendable holder (7). A hydraulic cylinder (8) which can be controlled by a control device (not shown) is used to adjust the height of the spreading disc (6). When it is actuated, the holder (7) is adjusted in its extension length to a specific load, or the holder (7) is increasingly lengthened by the hydraulic cylinder (8) during operation of the spreading vehicle. The extension is proportional to the rebound of the loading platform (1) due to the increasing emptying of the silo container (3). By extending the holder (7) the spreading disc (6) is always set at approximately the same height above the floor (9).
In der Fig. 1 sind zwei alternative Meßgeräte jeweils schematisch dargestellt, mit denen ein dem Ausfederweg der Ladepritsche (1) entsprechendes Ausgangssignal erzeugt wird, welches mittels eines nicht dargestellten Regelgeräts in ein Stellsignal zur Einstellung der Länge des teleskopischen Halters (7) umgewandelt wird.In Fig. 1, two alternative measuring devices are each shown schematically, with which an output signal corresponding to the spring deflection of the loading platform (1) is generated, which is converted into a control signal for adjusting the length of the telescopic holder (7) by means of a control device (not shown).
Eine erste Alternative zum Messen der Pritschenhöhe ist ein elektronisches Meßgerät (10), welches die Entfernung vom Boden (9) z.B. mittels eines Laserstrahls (11) mißt.
Eine zweite Alternative ist ein mechanisches Meßgerät (12), welches mittels eines Tasthebels (13), der am Differentialgehäuse (14) angelenkt ist, die Abstandsveränderung zwischen Ladepritsche (1) und Fahrzeugachse (2) mißt. Selbstverständlich benötigen beide Arten von Meßgeräten eine Dämpfung bzw. Glättung in der Art, daß Schwingungen des Fahrzeugaufbaus infolge von Stößen bei Fahrbahnunebenheiten unterdrückt werden.A first alternative for measuring the platform height is an electronic measuring device (10) which measures the distance from the floor (9), for example by means of a laser beam (11).
A second alternative is a mechanical measuring device (12) which measures the change in distance between the loading platform (1) and the vehicle axle (2) by means of a feeler lever (13) which is articulated on the differential housing (14). Of course, both types of measuring devices require damping or smoothing in such a way that vibrations of the vehicle body due to bumps on uneven road surfaces are suppressed.
Während die normale Abwurfhöhe des Streutellers (6) etwa bei 30 cm eingestellt ist, wenn der Silobehälter (3) voll beladen ist, kann es im Betrieb mit dessen zunehmender Entladung ohne die erfindungsgemäße Einrichtung zu einem Anheben des Streutellers um ca. 15 bis 20 cm kommen. In horizontaler Richtung bedeutet dies eine unerwünschte Vergrößerung der ursprünglich eingestellten maximalen Streubreite von ca. 3 m auf ca. 4 m. Durch die erfindungsgemäße Einrichtung gelingt es, den Streuteller (6) unverändert in seiner anfänglich eingestellten Höhe über dem Boden während des gesamten Streueinsatzes zu halten. Die eingestellte Höhe richtet sich dabei nach der gewünschten Wurfweite des Streuguts. Diese ist eine Funktion nicht nur der Höhe des Streutellers über dem Boden sondern auch der Drehzahl des Streutellers.While the normal discharge height of the spreading plate (6) is set at about 30 cm when the silo container (3) is fully loaded, it can increase in operation with its increasing discharge without the device according to the invention by about 15 to 20 cm come. In the horizontal direction, this means an undesired increase in the originally set maximum spreading width from approx. 3 m to approx. 4 m. The device according to the invention succeeds in keeping the spreading disc (6) unchanged in its initially set height above the ground during the entire spreading operation. The set height depends on the desired spreading distance of the spreading material. This is a function not only of the height of the spreading disc above the ground but also of the speed of the spreading disc.
