Definitions

  • the invention relates to a material feed container, in particular for concrete pumps, with one filling opening and one overlapping the filling opening Sieve grill, which has a bar grid with equidistant bar division.
  • the grill has a sieve function, depending on the grain of the concrete aggregates a different division of the staff is required.
  • the invention has for its object a material feed container to develop the type specified at the beginning, in which the division of the staff of the screen grill can be changed with simple means.
  • the solution according to the invention is based on the idea that the screen grill a basic grill with a basic grid with equidistant bar division and has an additional grid that can be optionally placed on the basic grid, the basic grid together with the additional grid a combination grid with equidistant, smaller bar division compared to the basic grid.
  • the additional grid advantageously has the same bar division as that Basic grid and is offset by half the grid constant from the Basic grid arranged.
  • An equidistant division of the bars in the combination grid To ensure, it is advantageous if the additional grating across The direction of the rod cannot be fixed to the basic grille.
  • a preferred embodiment of the invention provides that the additional grid Is part of a folding grill, which is preferably in the area of the container edge is hinged to the basic grill.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • the rod interspace of the basic grid 28 is divided by two rods each of the additional grid 30.
  • 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.
  • 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).
  • 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.
  • 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.
  • different bar divisions can be easily set on the screen grill 20 for concretes with different grain sizes.
