Description

Die Erfindung betrifft einen Siebbelag mit auf seiner Oberseite befestigter Stauleiste.The invention relates to a screen covering with attached on its top Storage bar.

Stauleisten werden auf Sieboberflächen angebracht und dienen zum Anstauen, Umleiten, Aufreißen von Siebgut und zum Verringern der Transportgeschwindigkeit. Die Befestigung solcher Stauleisten auf den Sieben erfolgt durch Schrauben oder Kleben. Ein Auswechseln von Stauleisten ist daher umständlich und aufwendig. Sind Stauleisten verklebt, werden sie beschädigt oder sogar zerstört. Vielfach wird daher der Siebboden selbst mit beschädigt.Ram bars are attached to the screen surfaces and are used for accumulation, Redirecting, tearing up screenings and reducing the Transport speed. Attachment of such ram bars to the seven done by screwing or gluing. It is therefore necessary to replace the storage rails cumbersome and complex. If damming strips are glued, they are damaged or even destroyed. Often, the sieve bottom itself is also damaged.

Aufgabe der Erfindung ist es, einen Siebbelag mit Stauleiste so zu verbessern, daß die Stauleiste auf dem Siebbelag einfach und leicht befestigbar und auswechselbar ist.The object of the invention is to improve a screen covering with a baffle bar so that the baffle bar on the screen covering simple and easy to attach and is interchangeable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Siebbelag an seiner Oberseite eine Ausnehmung insbesondere eine Nut aufweist, die parallel zur Stauleiste verläuft und in der ein unterer Bereich der Stauleiste formschlüssig einliegt.This object is achieved in that the screen covering its top has a recess, in particular a groove, which is parallel runs to the damming bar and in the lower area of the damming bar form-fitting lies in.

Die Stauleiste ist leicht von Hand auf dem Siebbelag montierbar und hierbei sicher in der Nut des Siebbelages gehalten. Bei der Demontage wird weder der Siebbelag noch die Stauleiste beschädigt. The storage rail is easy to assemble by hand on the screen covering and is safe held in the groove of the screen. When dismantling, neither Screen covering still damaged the storage ledge.

Eine besonders einfache und sichere Befestigung der Stauleiste wird dann erreicht, wenn der untere Bereich der Stauleiste durch eine Schnappverbindung in der Nut befestigbar ist. Auch ist von Vorteil, wenn der Querschnitt des unteren Bereichs der Stauleiste gleich dem Querschnitt der Nut ist.A particularly simple and secure attachment of the storage bar is then reached when the lower area of the storage rail by a snap connection in the groove is attachable. It is also advantageous if the cross section of the lower one Area of the baffle bar is equal to the cross section of the groove.

Ein besonders sicherer Halt der Stauleiste ist dann gegeben, wenn eine Seitenwand oder beide Seitenwände der Nut hinterschnittene Längsausnehmungen aufweist/aufweisen. Hierbei kann die Längsausnehmung einer Seitenwand der Nut einen unüberwindbaren Halt für den in der Längsausnehmung einliegenden leistenförmigen Vorsprung des unteren Stauleistenbereichs bilden. Alternativ wird vorgeschlagen, daß die Längsausnehmung einer Seitenwand der Nut einen überwindbaren Halt für den in der Längsausnehmung einliegenden leistenförmigen Vorsprung des unteren Stauleistenbereichs bildet.A particularly secure hold of the storage rail is given if one Side wall or both side walls of the groove undercut Has / have longitudinal recesses. Here, the longitudinal recess one side wall of the groove an insurmountable hold for the in the The longitudinal recess of the lower strip-shaped projection Form the ridge area. Alternatively, it is proposed that the Longitudinal recess of a side wall of the groove an insurmountable hold for the in the longitudinal recess in the strip-shaped projection of the lower one Congestion area forms.

Besonders vorteilhaft ist es, wenn der aus der Nut nach oben über die Sieboberseite hinausreichende obere Bereich der Stauleiste entsprechend den Erfordernissen der Stauleiste geformt ist. Hierbei kann der obere Bereich der Stauleiste Zähne bilden. Auch ist von Vorteil, wenn die Zähne in Fließrichtung des Siebgutes geneigt sind. Hierbei können sich die Zähne im senkrechten Querschnitt und/oder senkrechten Längsschnitt sich nach oben hin verjüngen.It when the from the groove up over the Upper area of the damming bar which extends above the sieve in accordance with the Requirements of the storage rail is shaped. The upper area of the Form ridge bar teeth. It is also an advantage if the teeth are in the direction of flow Are inclined. Here, the teeth can be vertical Cross-section and / or vertical longitudinal section taper towards the top.

Der Siebbelag 1 einer Siebmaschine ist aus Kunststoff insbesondere aus Polyurethan gefertigt und besitzt an seiner Oberseite 2 Ausnehmungen in Form von Nuten 3, die sich zur Oberseite hin öffnen und deren Höhe geringer ist als die Höhe bzw. Dicke des Siebbelages 1.The screen covering 1 of a screening machine is made of plastic in particular Made of polyurethane and has 2 recesses in shape on its top of grooves 3 that open towards the top and whose height is less than that Height or thickness of the screen covering 1.

Die Nut 3 besitzt einen zur Oberseite 2 parallelen Boden 4 und zwei Seitenwände, das heißt eine vordere Seitenwand 5 und eine hintere Seitenwand 6. Hierbei ist die vordere Seitenwand 5 der Seite des Siebfeldes näher, an der das Siebgut aufgegeben wird, und die hintere Seitenwand 6 ist der Seite der Siebfläche näher, an der das auf der Oberseite verbliebene Siebgut abgegeben wird, so daß in Fließrichtung F des Siebgutes die vordere Seitenwand zuerst kommt und dann erst die hintere Seitenwand 6.The groove 3 has a bottom 4 parallel to the top 2 and two side walls, that is, a front side wall 5 and a rear side wall 6. Here the front side wall 5 closer to the side of the screen field on which the material to be screened is given up, and the rear side wall 6 is closer to the side of the screen surface, at which the screenings remaining on the top are released, so that in Direction of flow F of the screened material, the front side wall comes first and then only the rear side wall 6.

Die vordere Seitenwand 5 der Nut 3 besitzt eine nutenförmige Längsausnehmung 7 mit einer stufenförmigen Hinterschneidung 8, die somit einen Rücksprung mit einer rückspringenden Fläche bildet, die parallel zur Oberseite 2 ist. Die hintere Seitenwand 6 bildet auch eine Längsausnehmung 9, deren Hinterschneidung 10 von einer Fläche gebildet wird, die nicht parallel, sondern schräg zur Oberseite 2 liegt.The front side wall 5 of the groove 3 has a groove-shaped longitudinal recess 7 with a step-shaped undercut 8, which thus has a recess forms a recessed surface that is parallel to the top 2. The rear one Side wall 6 also forms a longitudinal recess 9, the undercut 10 of which is formed by a surface that is not parallel but at an angle to the top 2 lies.

In der Nut 3 liegt der untere Bereich 12a einer Stauleiste 12 formschlüssig ein, so daß der senkrechte Querschnitt des unteren Bereichs 12a identisch in Größe und Form ist mit dem Querschnitt der Nut 3. Hierdurch liegt ein unterer seitlicher leistenförmiger Längsvorsprung 12b der Stauleiste 12 formschlüssig in der Längsausnehmung 7 ein, so daß an dieser Stelle die Längsausnehmung 7 und der Längsvorsprung 12b ein Formgesperre bilden.In the groove 3, the lower region 12a of a baffle bar 12 is positively inserted, so that the vertical cross section of the lower region 12a is identical in size and Shape is with the cross section of the groove 3. This is a lower side strip-shaped longitudinal projection 12b of the baffle bar 12 in a form-fitting manner Longitudinal recess 7, so that at this point the longitudinal recess 7 and the longitudinal projection 12b form a locking mechanism.

Der untere Bereich 12a der Stauleiste bildet auf der anderen Seite einen Längsvorsprung 12c, der formschlüssig in der Längsausnehmung 9 der Nut 3 einliegt. An dieser Seite ist aber die obere Wand der Längsausnehmung 9 schräg zur Oberseite 2 angeordnet, so daß der Längsvorsprung 12c mit der Längsausnehmung 9 ein Formgehemme bilden, so daß bei Kraftanwendung auf die Stauleiste 12 in Richtung des Pfeiles P der Längsvorsprung 12c aus der Längsausnehmung 9 herausgehoben werden kann. The lower area 12a of the storage bar forms one on the other side Longitudinal projection 12c, which has a positive fit in the longitudinal recess 9 of the groove 3 lies in. On this side, however, the upper wall of the longitudinal recess 9 is oblique arranged to the top 2, so that the longitudinal projection 12c with the Longitudinal recess 9 form a mold, so that when force is applied the baffle bar 12 in the direction of arrow P of the longitudinal projection 12c from the Longitudinal recess 9 can be lifted out.

Die Stauleiste 12 ist von Hand montierbar, indem die Leiste schräg gegen die Förderrichtung F gekippt wird, damit die Feder bzw. der Längsvorsprung 12b in den unteren Bereich zuerst eingeführt wird und somit unter die Belastungssicherung bzw. die Hinterschneidung 8 greifen kann. Danach wird die Stauleiste, bei gleichzeitigem Druck gegen den Siebboden, in die winkelrechte Stellung gebracht. Dabei gleitet die Montageschräge über die Widerstandsnase, bis die Sperre bzw. der Längsvorsprung 12c in die Längsausnehmung 9 (Prismennut) einschnappt.The storage bar 12 can be assembled by hand by slanting the bar against the Conveying direction F is tilted so that the spring or the longitudinal projection 12b in the lower area is introduced first and thus under the Load securing or the undercut 8 can grip. After that the The ram bar, with simultaneous pressure against the sieve bottom, into the right angle Positioned. The assembly slope slides over the resistance tab, until the lock or the longitudinal projection 12c into the longitudinal recess 9 (Prism groove) snaps into place.

Die Belastung der Stauleiste durch das Siebgut ist durch

  • die Feder in der Nut,
  • die Verdrehsicherung über der Feder,
  • die Abstützung der Widerstandsnase
    • gegen ein Herauskippen gesichert.The load on the damming bar by the screenings is through
  • the tongue in the groove,
  • the anti-rotation device over the spring,
  • the support of the resistance nose
    • secured against tipping out.

    Eine Demontage der Stauleiste erfolgt, indem mit einem Hammerschlag im oberen Bereich der Stauleiste gegen die Förderrichtung geschlagen wird, so daß die Sperre - begünstigt durch die Demontageschräge - über die Widerstandsnase herausspringt.Disassembly of the storage rail is done by hitting the top with a hammer Area of the damming bar is struck against the conveying direction, so that the Lock - favored by the bevels - via the resistance nose pops out.

    Im Besonderen ist die Stauleiste als Aufreißleiste 12d, die zur Auflockerung des Siebgutes dient, mit vorzugsweise konischen Zähnen 15 und/oder Spalten 16 ausgebildet, die insbesondere dann wirkungsvoll arbeiten, wenn sie in Förderrichtung F geneigt sind.In particular, the baffle bar as a tear bar 12d, which is used to loosen the Serves good, preferably with conical teeth 15 and / or gaps 16 trained who work particularly effectively when they are in Direction of conveyance F are inclined.
