Die in Fig. 1 dargestellte fahrbare Betonpumpe besteht im wesentlichen aus einem Fahrgestell 10, einer auf dem Fahrgestell angeordneten Dickstoffpumpe 12, die saugseitig mit einem Materialaufgabebehälter 14 und druckseitig mit einem Betonförderrohr 16 kommuniziert. Weiter ist ein auf dem Fahrgestell 10 angeordneter, einen beweglichen Teil des Betonförderrohrs 16 tragender, als Knickmast ausgebildeter Verteilermast 18 vorgesehen.The mobile concrete pump shown in Fig. 1 consists essentially of a chassis 10, a thick matter pump arranged on the chassis 12, the suction side with a material feed container 14 and the pressure side communicated with a concrete delivery pipe 16. Next is one on the Chassis 10 arranged, a movable part of the concrete delivery pipe 16 load-bearing, designed as an articulated boom 18.

Die Einfüllöffnung des Materialaufgabebehälters wird von einem Siebgrill 20 übergriffen, dem eine Siebfunktion für die Zuschlagstoffe des einzufüllenden Betons zukommt. Für Betone mit verschiedener Körnung besteht der Siebgrill 20 aus einem Grundgrill 22 und einem im Bereich des Behälterrandes 24 an diesem angelenkten Klappgrill 26. Der Grundgrill weist dabei ein Grundgitter 28 mit äquidistanter Stabteilung T1 auf, während der Klappgrill 26 ein Zusatzgitter 30 aufweist, das zusammen mit dem Grundgitter 28 ein Kombinationsgitter mit äquidistanter, gegenüber dem Grundgitter kleinerer Stabteilung T2 (Fig. 3b) oder T3 (Fig. 3c) bildet. Im Falle der Fig. 3b weist das Zusatzgitter die gleiche Stabteilung wie das Grundgitter auf und ist um die halbe Gitterkonstante versetzt gegenüber dem Grundgitter angeordnet. Bei dem Ausführungsbeispiel nach Fig. 3c ist der Stabzwischenraum des Grundgitters 28 durch jeweils zwei Stäbe des Zusatzgitters 30 unterteilt. Um eine äquidistante Stabteilung zu erhalten, ist das Zusatzgitter 30 quer zur Stabrichtung unverrückbar mit dem Grundgitter 28 verbunden. Der Grundgrill 22 ist bei hochgeklapptem Klappgrill 26 eher für grobe Betonzuschläge bestimmt. Für feinere Betonzuschläge wird der Klappgrill 26 unter Bildung des Kombinationsgitters gemäß Fig. 3b oder 3c in die Ebene des Grundgrills 22 geklappt. Der Schwenkwinkel zwischen Klappgrill und Grundgrill beträgt bei dem gezeigten Ausführungsbeispiel ca. 45° (Fig. 2).The filling opening of the material feed container is overlapped by a screen grill 20, which has a screen function for the aggregates of the concrete to be filled. For concretes with different grain sizes, the screen grill 20 consists of a basic grill 22 and a folding grill 26 hinged to it in the area of the container edge 24. The basic grill has a basic grid 28 with equidistant bar division T 1 , while the folding grill 26 has an additional grid 30 which together with the basic grid 28 forms a combination grid with equidistant rod division T 2 (FIG. 3b) or T 3 (FIG. 3c) which is smaller than the basic grid. In the case of FIG. 3b, the additional grid has the same bar division as the basic grid and is arranged offset by half the grid constant with respect to the basic grid. In the exemplary embodiment according to FIG. 3c, the rod interspace of the basic grid 28 is divided by two rods each of the additional grid 30. In order to obtain an equidistant bar division, the additional grid 30 is immovably connected to the basic grid 28 transversely to the bar direction. The basic grill 22 is more intended for coarse concrete surcharges when the folding grill 26 is folded up. For finer concrete aggregates, the folding grill 26 is folded into the plane of the basic grill 22 to form the combination grill according to FIG. 3b or 3c. The swivel angle between the folding grill and the basic grill is approximately 45 ° in the exemplary embodiment shown (FIG. 2).

Zusammenfassend ist folgendes festzuhalten: Die Erfindung bezieht sich auf einen Materialaufgabebehälter, insbesondere für Betonpumpen. Die Einfüllöffnung des Materialaufgabebehälters wird von einem Siebgrill 20 übergriffen, der aus einem Grundgrill 22 mit einem Grundgitter 28 mit äquidistanter Stabteilung T1 sowie einem Klappgrill 26 mit einem Zusatzgitter 30 besteht. Im eingeklappten Zustand bildet das Grundgitter 28 zusammen mit dem Zusatzgitter 30 ein Kombinationsgitter mit äquidistanter, gegenüber dem Grundgitter 28 kleinerer Stabteilung T2,T3. Damit lassen sich für Betone mit verschiedener Körnung auf einfache Weise unterschiedliche Stabteilungen am Siebgrill 20 einstellen.In summary, the following can be stated: The invention relates to a material feed container, in particular for concrete pumps. The filling opening of the material feed container is overlapped by a screen grill 20, which consists of a base grill 22 with a base grill 28 with equidistant bar division T 1 and a folding grill 26 with an additional grill 30. In the folded state, the basic grille 28 together with the additional grille 30 forms a combination grille with equidistant rod division T 2 , T 3 , which is smaller than the basic grille 28. In this way, different bar divisions can be easily set on the screen grill 20 for concretes with different grain sizes.
