Herkömmliche Siebroste zum groben Trennen von Schüttgütern bestehen aus Querbalken mit größeren Abständen und ein- oder aufgeschraubten bzw. ein- oder aufgeschweißten Roststäben mit kleineren Abständen. Entsprechend der Anordnung der Querbalken und der Roststäbe ergeben sich Spalten. Die Roste können eben, mit einer Neigung und/oder in Stufen angeordnet sein. Der Werkstoff dieser Roste ist aus Stahl. Sind die Roste zusammengeschraubt, so sind Montage und Demontage aufwendig. Sind sie zusammengeschweißt, so sind Montage und Demontage auch aufwendig und es können keine einzelnen Roststäbe gewechselt werden, sondern es muß der gesamte verschweißte Rahmen ausgewechselt werden. Ferner besteht die Gefahr der Rostbildung. Bei weicheren abzusiebenden / zu entwässernden Materialien (zum Beispiel Hackfrüchte wie Kartoffeln, Rüben etc.) erfolgt eine Beschädigung durch die harten Werkstoffe.Conventional sieve grids for rough separation of Bulk goods consist of crossbeams with larger ones Distances and screwed or screwed or on or welded-on grate bars with smaller distances. According to the arrangement of the crossbars and the Rust bars result in gaps. The grates can be arranged with an inclination and / or in steps. The material of these gratings is made of steel. Are the grates screwed together, so are assembly and disassembly complex. If they are welded together, there is assembly and disassembly also complex and it can not individual grate bars to be replaced, but it must the entire welded frame can be replaced. There is also a risk of rust formation. For softer ones materials to be screened / dewatered (for Example root crops such as potatoes, beets, etc.) damage from the hard materials.

Der Rost weist mindestens zwei Querbalken 1 und daran lösbar befestigte Roststäbe 2 auf. Der für Querbalken und Roststäbe verwendete Werkstoff ist gummielastisch vorzugsweise Polyurethan 5. Die Querbalken sowie die Roststäbe können mit Armierungen versehen sein. Die Querbalken enthalten nach oben offene Montageausnehmungen 6, in denen die Roststäbe 2 von Hand von oben reingedrückt werden. Eine insbesondere sägezahnförmige Arretierungsausnehmung 7 in der Montageausnehmung 6 im Querbalken 1 und ein Arretierungsvorsprung 8 gleichen Querschnitts am Roststab 2 verhindern ein ungewolltes Lösen, das durch die Beaufschlagungsvibration erfolgen könnte. The grate has at least two crossbeams 1 and 1 releasably attached grate bars 2. The one for crossbeams and grate bars used is rubber-elastic preferably polyurethane 5. The cross beams and the Grate bars can be provided with reinforcements. The Crossbars contain open ones Mounting recesses 6 in which the grate bars 2 from Be pushed in from above. One in particular sawtooth-shaped locking recess 7 in the Mounting recess 6 in the crossbar 1 and a Locking projection 8 of the same cross section on Grate bar 2 prevent accidental loosening by the application vibration could occur.

Durch den Abstand der Montageausnehmungen 6 im Querbalken und der Roststabbreite wird die Spaltweite bestimmt. Die Spaltlänge wird durch den Abstand der Querbalken bestimmt. Die Roststäbe 2 haben vorzugsweise ein im Querschnitt sich nach unten verjüngendes Profil im Spaltbereich, um die Klemmung von Grenzkorn zu vermeiden. Zur weiteren Schonung von "weichem" Siebgut und zum besseren Entwässerungseffekt kann das Kopfprofil des Roststabes vorzugsweise abgerundet ausgebildet sein (Fig. 4, 5, 6).By the distance of the mounting recesses 6 in Crossbar and the grate bar width becomes the gap width certainly. The gap length is determined by the distance between the Crossbar determined. The grate bars 2 preferably have a profile tapering downward in cross section Gap area to avoid the jamming of boundary grain. For further protection of "soft" screenings and for the head profile of the Grate bar preferably be rounded (Fig. 4, 5, 6).

Vorzugsweise ist das Montageprofil 9 jeweils stirnseitig an den Enden der Roststäbe 2 angeordnet. Die Montageprofile 9 können auch mittig an den Roststäben 2 angebracht sein. Damit liegen die Oberseiten der Querbalken 1 sowie die der Roststäbe 2 auf einer Ebene. Um die offene Siebfläche zu vergrößern, können die Montageprofile an den Roststäben nach unten hervorstehen (Fig. 8a). Im montierten Zustand verlaufen die Roststäbe dann über den Querbalken, die so einen durchgehenden Spalt bilden.The mounting profile 9 is preferably at the end arranged at the ends of the grate bars 2. The Mounting profiles 9 can also be centered on the grate bars 2 to be appropriate. This is the top of the Crossbar 1 and that of the grate bars 2 on one level. To increase the open screen area, the The mounting profiles on the grate bars protrude downwards (Fig. 8a). The grate bars run when assembled then over the crossbar, which is such a continuous Form a gap.

Es ist üblich, daß der Spaltverlauf parallel ist und das Montageprofil 9 kantig ausgeführt ist. Sobald aber ein konischer Spaltverlauf notwendig wird, erreicht man dies durch eine in Förderrichtung sich verjüngende Ausbildung der Roststäbe und/oder durch eine sich einander weitende Anordnung der Roststäbe (Fig. 9, 10), so daß die Spalten zwischen den Roststäben sich weiten. Hierbei ist das Montageprofil vorzugsweise rund, insbesondere zylindrisch (Fig. 9, 10) ausgebildet, das heißt die Montageprofile sind nach unten (Fig. 9a bis 9c) oder stirnseitig (Fig. 10a bis 10c) an den Roststäben vorstehende Teile, insbesondere Zapfen mit insbesondere rundem waagerechtem Querschnitt und insbesondere zylindrischer Form mit senkrechter Zylinderachse. Damit wird gleichzeitig ein Verteilen des Siebgutes erreicht.It is common for the gap to be parallel and that Mounting profile 9 is angular. But as soon as one conical gap course is necessary, this is achieved through tapering training in the direction of conveyance the grate bars and / or by a widening one another Arrangement of the grate bars (Fig. 9, 10) so that the columns widen between the grate bars. Here is that Mounting profile preferably round, especially cylindrical (Fig. 9, 10) formed, that is, the mounting profiles are down (Fig. 9a to 9c) or face (Fig. 10a to 10c) parts protruding from the grate bars, especially cones with in particular round horizontal cross section and in particular cylindrical shape with vertical cylinder axis. In order to distribution of the screenings is achieved at the same time.

Zur Spaltsicherung (Fig. 2a und 2b) können vorzugsweise im unteren Bereich der Roststäbe ein- oder beidseitig Distanznoppen (3a und 3b) seitlich angearbeitet sein.To secure the gap (Fig. 2a and 2b) can preferably in the lower area of the grate bars on one or both sides Spacer knobs (3a and 3b) must be worked in on the side.

Zur dynamischen Beanspruchung eines Profil-Rostes ist vorzugsweise ein nach unten sich verjüngendes Montageprofil 9 vorzusehen (Fig. 11c), wobei die Flankenneigung 3-20 Grad, vorzugsweise 5-10 Grad sein sollte und das Montageprofil mit einem Übermaß zu fertigen ist, um einen sicheren Halt am Querbalken zu erreichen.For the dynamic loading of a profile grate preferably a tapering downward Provide mounting profile 9 (Fig. 11c), the Flank slope 3-20 degrees, preferably 5-10 degrees should and the mounting profile with an oversize is to ensure a secure hold on the crossbeam to reach.

Für eine zusätzliche Arretierung können waagerechte Bundbolzen 11 vorgesehen sein, die je zur Hälfte in halbzylindrischen Ausnehmungen des Montageprofils 9 und der Montageausnehmung 6 beidseitig des Montageprofils einliegen und damit vorzugsweise den Arretierungsvorsprung 8 und die Arretierungsausnehmung 7 ersetzen.For an additional locking, horizontal Collar bolts 11 are provided, each half in semi-cylindrical recesses of the mounting profile 9 and the mounting recess 6 on both sides of the mounting profile insert and therefore preferably the Locking projection 8 and the locking recess 7 replace.

Senkrechte Entwässerungs- bzw. Reinigungsöffnungen 10 (Fig. 9b) verlaufen vom Boden der Arretierungsausnehmung durch den Querbalken nach unten.Vertical drainage or cleaning openings 10 (Fig. 9b) extend from the bottom of the locking recess down through the crossbar.

Für durchgängige Spalten und einer größeren offenen Siebfläche können die Montageprofile unter den Profilstäben angeordnet sein. Demzufolge verlaufen die Querbalken unterhalb der Profilstäbe. Für eine dynamische Beanspruchung sind die Ausnehmungen und Montageprofile konisch ausgebildet. Um die Steifigkeit sowohl in der Längs- als auch in der Querachse zu erhöhen, können die Montageprofile 9 auch weiter zur Mitte hin am Profilstab 2 angebracht sein.For continuous gaps and a larger open one The mounting profiles under the Profile bars may be arranged. As a result, the Crossbeam below the profile bars. For a dynamic The recesses and mounting profiles are subject to stress conical. To the rigidity both in the To increase the longitudinal as well as in the transverse axis Mounting profiles 9 also further towards the center on the profile bar 2 be attached.
