   Die Erfindung bezieht sich auf eine Streuvorrichtung insbesondere Mist- und Kompoststreuer mit einer Zuführung für das Streugut, beispielsweise einer Wanne mit einer Vorschubeinrichtung, vorzugsweise einem Kratzbodenvorschub, einem von einem Maschinenrahmen getragenen Rotorgehäuse mit   e ! nem Zubnngerrotor   und mindestens einem bei einer Auswurföffnung angeordneten Auswurfrotor mit einem Auswurfrotorgehause, wobei die Auswurföffnung von Ablauf- und Anlaufkanten für das Streugut begrenzt wird, von denen eine über einen Teilbereich des Umfanges des Auswurfrotors versetzbar ist, und mit einer Antriebsvorrichtung. 



   Eine Streuvorrichtung dieser Art ist aus den CH 683 058 A und CH   674 693   A bekannt. 



   Die AT 398 680 B zeigt eine ähnliche Streuvornchtung mit einem Auswurfrotor, der schwenkbar am Rotorgehäuse gelagert ist. 



   Aufgabe der Erfindung Ist es, eine Streuvorrichtung der eingangs erwähnten Art mit veränderlichem Ausstreuwinkel dahingehend zu verbessern, dass eine einfachere Konstruktion erreicht wird
Die erfindungsgemässe Aufgabe wird dadurch erreicht, dass die Anlaufkante des Auswurfrotorgehauses über einen Teilbereich des Umfanges des Auswurfrotors versetzbar ist. 



   Dadurch, dass gemäss der Erfindung die Anlaufkante versetzbar angeordnet ist, kann der Ab-   streifer,   der - um beispielsweise Steine durchzulassen - nachgiebig angeordnet sein muss, am festen Gehäuseteil angeordnet sein. Gemäss dem Stand der Technik ist dieser nachgebende Teil des Streustators versetzbar, was zu einem hohen konstruktiven Aufwand führt. 



   Vorzugsweise ist vorgesehen, dass an dem mindestens einem Auswurfrotorgehäuse ein Leltblech verschiebbar gelagert ist, an dem die Anlaufkante angeordnet ist. 



   Ein Ausführungsbeispiel der Erfindung sieht vor, dass eine Fladenleiste zumindestens annahernd um die Drehachse des Auswurfrotors zwischen der Ablaufkante und der Anlaufkante verschwenkbar ist. 



   Damit die   erfindungsgemässe   Streuvorrichtung nach beiden Selten ausstreuen kann, ist In einem bevorzugten   Ausführungsbeispiel   der Erfindung vorgesehen, dass zwei an einander gegenüberliegenden Seiten des Rotorgehäuse angeordnete Auswurfrotoren und Auswurfrotorgehäuse vorgesehen sind oder dass das Rotorgehäuse mit dem Auswurfrotor und dem Auswurfrotorgehäuse um eine horizontale Achse drehbar ist. 



   Nachfolgend werden verschiedene   Ausführungsbeispiele   der Erfindung anhand der Figuren der beiliegenden Zeichnungen beschneben. 



   Die Fig. 1 zeigt eine schematisch gehaltene Seitenansicht einer   erfindungsgemassen   Streuvornchtung und die Fig. 2 bis 7 zeigen verschiedene Ausführungsbeispiele der Erfindung in Schnitten   gemäss   der Linie   i-i   der Fig.

   The invention relates to a spreading device, in particular manure and compost spreaders with a feed for the spreading material, for example a trough with a feed device, preferably a scraper floor feed, a rotor housing carried by a machine frame with e! a feed rotor and at least one ejection rotor arranged at an ejection opening with an ejection rotor housing, the ejection opening being limited by run-off and leading edges for the spreading material, one of which can be displaced over a partial area of the circumference of the ejection rotor, and with a drive device.



   A spreading device of this type is known from CH 683 058 A and CH 674 693 A.



   AT 398 680 B shows a similar spreading device with an ejection rotor that is pivotally mounted on the rotor housing.



   The object of the invention is to improve a spreading device of the type mentioned at the outset with a variable spreading angle in such a way that a simpler construction is achieved
The object according to the invention is achieved in that the leading edge of the ejection rotor housing can be displaced over a partial area of the circumference of the ejection rotor.



   Due to the fact that, according to the invention, the leading edge is arranged so as to be displaceable, the scraper, which - for example to let stones pass - must be arranged flexibly, can be arranged on the fixed housing part. According to the prior art, this compliant part of the scattering stator can be moved, which leads to a high level of structural complexity.



   It is preferably provided that on the at least one ejection rotor housing, a tent plate is slidably mounted, on which the leading edge is arranged.



   An embodiment of the invention provides that a flat bar can be pivoted at least approximately about the axis of rotation of the ejection rotor between the trailing edge and the leading edge.



   In order for the spreading device according to the invention to be able to spread in both cases, it is provided in a preferred exemplary embodiment of the invention that two ejection rotors and ejection rotor housings arranged on opposite sides of the rotor housing are provided or that the rotor housing with the ejection rotor and the ejection rotor housing can be rotated about a horizontal axis.



   Various exemplary embodiments of the invention are described below with reference to the figures in the accompanying drawings.



   1 shows a schematic side view of a scattering device according to the invention and FIGS. 2 to 7 show different exemplary embodiments of the invention in sections along the line i-i of FIG.

Claims

1. The manure and compost spreader according to the invention can be designed both as a pure structure which is to be piggybacked by a vehicle or as a trailer. In general, the spreading device will carry the spreading material, for example manure, on a loading area The manure and compost spreader has a tub 1, which is advantageously provided with a scraper floor feed. The rotor housing 2 connects to the tub 1 The feeder rotor 3 and the ejection rotor 4 are located in the rotor housing 2. The feeder rotor 3 has a much larger diameter than the ejection rotor 4 and moves at a lower rotational speed. Both rotors 3, 4 are provided with ejection blades. The ejection rotor 4 and the feed rotor 3 are advantageously driven by the PTO of the towing vehicle, the feed rotor 3 and the ejection rotor 4 being driven via a shaft and V-belt or the like.

The discharge openings 7 are aligned on opposite sides, so that manure can be spread on both sides with the spreading device according to the invention according to FIG. 6, without it being necessary to rotate the rotor housing 2 In the exemplary embodiment according to FIG. 7, an ejection funnel 15 connects to each ejection opening 7. The ejection funnel 15 is formed by at least one, preferably two, separate folding plates 16, so that the ejection funnel 15 can be pivoted approximately about the axis of rotation of the respectively associated ejection rotor 4, thereby changing the position of the leading edge and the trailing edge 6.
