Definitions

  • the present patent application relates to a mixer for concrete and similar mixtures, provided with two mixing shafts with horizontal axis assisted by double motorization.
  • mixers for concrete or similar mixtures currently comprise a large tank with two counter-rotating shafts with horizontal axis, on which series of radial arms used to mix the compound contained in the tank are fitted.
  • each shaft is fitted and supported on two opposite walls of the tank, it being also provided that on the outside of the tank one end of each shaft is coupled with the geared motor capable of rotating the shaft, while the other end of the shaft is supported by a suitable bearing fixed to the wall of the tank.
  • each mixing shaft is assisted by a very powerful geared motor.
  • the purpose of the present invention is to realise mixers with very large mixing tanks with respect to ordinary mixers, thus avoiding the need of manufacturing the expensive "special" geared motors with large dimensions mentioned above.
  • each geared motor is fitted to each mixing shaft of the mixer. More precisely, each geared motor must be applied to one end of the mixing shaft externally on the tank wall.
  • the mixer (1) comprises a rectangular mixing tank (2) provided with a cover (3) with lateral openings (3a).
  • the ends of two counter-rotating parallel mixing shafts with horizontal axis are fitted to the transversal walls (4) of the tank (2).
  • each end of each shaft is coupled with a geared motor (5) of standard dimensions and power located externally on the bearing wall (4) of the tank (2).
