Abstract

The spreading device is intended especially for moist spreading material. It consists of a spreading-material supply container arranged on an undercarriage and having a spreading-material outflow orifice and of at least one rotatably driven spreading plate arranged in the region of the latter. A rotatable metering plate (3) is arranged under the orifice (1) of the supply container (2). At at least one point on the circumference of the metering plate is the at least one spreading plate (4), and above the metering plate (3) is at least one spreading-material discharge strip (5) pointing in the direction of the spreading plate (4) and set at an angle to the radius. In the region of the discharge end (6) of the strip (5), the wall (2') limiting the orifice (1) of the supply container (2) is provided with a spreading-material outlet orifice (7). <IMAGE>

Description

Streugutaustragsleiste nicht mehr im Wege ist. Zusätzliche Abschirmelemente, wie bei der Vorrichtung nach der FR-PS 21 25 811, sind nicht erforderlich, wobei ein Rundumabfall des Streugutes vom Drehboden durch den unteren Rand des Vorratsbehälters selbst verhindert ist.Grit discharge bar is no longer in the way. Additional Shielding elements, as in the device according to FR-PS 21 25 811, are not required, with a All-round waste of the spreading material from the rotating floor is prevented by the lower edge of the storage container itself is.

Die Streuvorrichtung wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert. Es zeigt schematischThe spreading device is illustrated below with the aid of the drawings of exemplary embodiments explained in more detail. It shows schematically

In allen Figuren ist das zur Vorrichtung gehörende Fahrgestell nicht dargestellt. Unter Fahrgestell ist dabei zu verstehen jede Art von dafür geeigneten fahrbaren Untersätzen, d. h. insbesondere Traktoren mit entsprechenden Einrichtungen zur Aufnahme und Halterung der ganzen Streuvorrichtung und zum Antrieb des Streutellers 4 und des Drehbodens 3. Wie aus F i g. 1 erkennbar, ist der Vorratsbehälter 2 zylindrisch und nach unten über seinen gesamten Querschnitt offen ausgebildet, dort aber allerdings durch den entsprechend querschnittsgroßen Drehboden 3 abgedeckt, der mit seiner Drehachse 3' in einem Rohr 9 gelagert ist. Das Rohr 9 ist durch Speichen 10 bzw. Stege zentral im Vorratsbehälter 2 gehalten. Die Lagerung der Drehachse 3' kann axial verstellbar ausgebildet sein, um bspw. während des Transportes den Drehboden 3 fest gegen den unteren Rand des Vorratsbehälters 2 anlegen zu können. Der mögliche Verstellweg dafür muß nicht groß sein.The chassis belonging to the device is not shown in any of the figures. Under the chassis is included to understand any kind of suitable mobile pedestal, d. H. especially tractors with appropriate Facilities for receiving and holding the entire spreading device and for driving the Spreading plate 4 and the rotating base 3. As shown in FIG. 1 can be seen, the reservoir 2 is cylindrical and downwards over its entire cross-section, but there, however, by the corresponding large cross-section rotating base 3, which is mounted with its axis of rotation 3 'in a tube 9. That Tube 9 is held centrally in storage container 2 by spokes 10 or webs. The bearing of the axis of rotation 3 'can be designed to be axially adjustable, for example in order to hold the rotating base 3 firmly against it during transport to be able to create the lower edge of the reservoir 2. The possible adjustment path for it does not have to be be great.

Unterhalb des Drehbodens 3 sitzt auf der Achse 3' ein Kettenrad J1, von dem aus der Drehboden 3 mit geeigneten Antriebsmitteln langsam gedreht wird. Mit diesem Antrieb kann auch, aber muß nicht, der Streuteller 4 angetrieben werden, der, wie erkennbar, und am nicht dargestellten Vorrichtungsgestell in geeigneter Weise gelagert, mit seiner Drehmitte auf den Umfangsrand des Drehbodens 3 orientiert ist.Below the rotating base 3 sits on the axis 3 'a chain wheel J1, from which the rotating base 3 with suitable Drive means is rotated slowly. With this drive, the spreading disc 4 can also, but does not have to be, are driven, which, as can be seen, and on the device frame, not shown, in a suitable manner stored, is oriented with its center of rotation on the peripheral edge of the rotating base 3.

Am unteren Ende des Rohres 9 ist auch die Streugutaustragsleiste 5 angeordnet, die vorteilhaft in bezug auf die Drehrichtung des Drehbodens 3 konvex gewölbt ausgebildet ist, so daß sich bei Drehung des Drehbodens 3 ein Materialschub in Richtung auf die Streugutaustragsöffnung 7 in der Wand 2' des Vorratsbehälters 2 ergibt Die öffnung 7 ist zweckmäßig in Drehrichtung hinter dem Ende 6 mit einem Verschlußschieber T versehen. At the lower end of the tube 9, the grit discharge bar 5 is arranged, which is advantageously curved convexly with respect to the direction of rotation of the rotary base 3, so that when the rotary base 3 is rotated, a material thrust in the direction of the grit discharge opening 7 in the wall 2 'of the Storage container 2 results. The opening 7 is expediently provided with a locking slide T behind the end 6 in the direction of rotation.

Vom Ende 6 der Streugutaustragsleiste 5 geführt, fällt dann das Streugut auf den Streuteller 4 und wird von diesem in bekannter Weise abgeschleudert bzw. verstreut. Die Streugutaustragsleiste 5 ist zweckmäßig in bezug auf die Streugutaustragsöffnung 7 einstellbar, so daß deren Querschnitt und damit die Austragsmenge variiert werden kann.From the end 6 of the grit discharge bar 5, the grit then falls onto the spreading plate 4 and is from this is thrown off or scattered in a known manner. The grit discharge bar 5 is useful in adjustable with respect to the grit discharge opening 7, so that its cross section and thus the discharge amount can be varied.

Der Antrieb des Drehbodens 3 ist vorteilhaft abhängig von der Geschwindigkeit des Fahrgestelles gestaltet, so daß bei geringer Geschwindigkeit entsprechend we- eo nig und bei größerer entsprechend mehr Streugut ausgetragen wird. Dabei spielt es also keine Rolle, mit welcher Drehzahl der Streuteller 4 läuft, da diese letztlich nur Einfluß auf die Streubreite hat.The drive of the rotating base 3 is advantageously designed depending on the speed of the chassis, so that correspondingly less spreading material is carried out at low speeds and correspondingly more spreading material is carried out at higher speeds will. It does not matter what speed the spreading plate 4 is running at, since this is ultimately the case only has an influence on the spread.

Eine Beschreibung der Antriebe für den Drehboden 3 und den Streuteller 4 im einzelnen erübrigt sich, da solche Antriebe (Hydraulikmotoren, Gelenkwellen, Winkeltriebe od. dgl.) einschließlich ihrer Koppelung bspw.A description of the drives for the rotating base 3 and the spreading plate 4 in detail is unnecessary, since such Drives (hydraulic motors, cardan shafts, angular drives or the like) including their coupling, for example.

mit Antriebselementen am Traktor ohne weiteres verfügbar sind und auch bei der vorliegenden Vorrichtung zur Anwendung kommen können.with drive elements on the tractor are readily available and also with the present device can be used.

Die Fig.4, 5 verdeutlichen nur, daß bei gleichem Grundprinzip, wie beschrieben, auch zwei Streuteller unterhalb eines Drehbodens 3 angeordnet werden können. The Fig.4, 5 only make it clear that with the same Basic principle, as described, two spreading plates can also be arranged below a rotating base 3.
