Definitions

  • the invention relates to a device for mixing a mixture formed as a mortar or screed mixture of several components mixed with a rotatable by a mixer shaft mixing, via a closable by means of a lid filling opening with at least one component of the mixable filling pressure vessel, which can be acted upon in operation with pressure Interior has an interspersed by the mixer mixing volume, and a motor for rotary drive of the mixer shaft.
  • the object of the invention is to further improve the devices known in the prior art and to specify a construction optimized with regard to the required engine power and secured against incorrect operation.
  • the invention is based on the idea of creating a compensating volume that can not be filled with material by the operator. Accordingly, it is proposed according to the invention that the interior comprises a deflection volume arranged above or above the height of the filling opening, wherein the escape volume communicates with the mixing volume at any rate when the lid is closed, and gives the mixture space to avoid during mixing. Due to the arrangement of the Dodge volume above the filling, it is the operator without special effort not possible to overfill the pressure vessel. At the same time it is ensured that a sufficiently large free space is available, in which material can be displaced during mixing. Furthermore, such an area is kept free, which can serve as an initial compression space when introducing compressed air.
  • a structurally particularly advantageous construction provides that the lid limits the escape volume.
  • a further improvement can be achieved in that the cover is designed as an attachable to the filling, upwardly closed hood.
  • the lid is pivotable against the filling opening via a cover hinge.
  • the pressure vessel has on its upper side an upwardly extending dome for limiting the escape volume.
  • a further advantageous embodiment provides that the filling opening through the lower edge of a top is formed in the interior projecting filler neck, and that the surrounding the filler neck portion of the interior forms the escape volume.
  • the horizontally arranged mixer shaft is offset eccentrically with respect to a horizontal center axis of the pressure vessel down or displaceable.
  • the escape volume should be at least 1/10, preferably at least 1/5 and preferably about 1/4 of the total volume of the interior.
  • the mixing plant has a mixing spiral sitting on the mixer shaft or a plurality of mixing blades projecting transversely to the mixer shaft.
  • the pressure vessel has a compressed air connection for a compressor operated by means of the engine. Again, the compensation volume can be beneficial for limiting the required maximum engine power.
  • the pressure vessel at its bottom having a connection for a delivery line for discharging the mixed material.
  • the pressure vessel is arranged on a chassis for transport to the place of use.
  • the screed mixer 10 shown in the drawing for mixing and conveying a screed mixture comprises a pressure vessel 12, a mixer 16 rotatable therein by means of mixer shaft 14 and a drive motor 18 for driving the mixer 14 and a Compressor 20.
  • the entire arrangement can be arranged as a truck mixer for a transport to the place of use.
  • the pressure vessel 12 can be acted upon via an upwardly facing filling opening 22 with the dry and liquid components of the screed mixture, as indicated by arrow 24.
  • the filling opening 22 can be closed in a pressure-tight manner by a lid 32, which is held pivotably on a hinge 30.
  • the pressure vessel 12 In the closed state, the pressure vessel 12 can be pressurized via the compressed air compressor 20, so that the mixture is discharged via an outlet 34 in a direction indicated by arrow 36 feed line.
  • the mixer 16 may have a sitting on the mixer shaft 14 mixing coil 38 and be coupled to a shaft end with the drive motor 16 designed as an internal combustion engine. This can also serve as a drive for the compressor 20, which is connected on the pressure side via a connection 40 to the pressure vessel 12.
  • an evacuation volume 42 is provided by the operator not additionally fillable with screed components.
  • the escape volume 42 should comprise at least 1/10 and preferably about 1/4 of the total volume of the pressure vessel 12.
  • the cover 30 limits the evasive volume 42, which communicates with the underlying closed mixing volume 44 through which the mixer 16 or its mixing helix 38 passes when the lid is closed.
  • the lid 30 is formed as an upwardly closed, elongated hood 46.
  • the same or similar parts are provided with the same reference numerals as described above.
  • the embodiment according to Fig. 2 differs in that the escape volume 42 is formed separately from the lid 30 by a dome 48 which extends on top of the pressure vessel 12 upwards and communicates with the mixing space 44.
  • Fig. 3 is the effective filling opening through the lower edge of a top-in the interior protruding filler neck 50 formed.
  • the low-lying filler neck 50 prevents easy filling of the upper interior region, which thus forms the escape volume 42.
  • the horizontally disposed mixer shaft 14 is arranged eccentrically offset with respect to a horizontal center axis 52 of the cylindrical pressure vessel 12 down.
