Definitions

  • the invention relates to a vehicle for the transport of hydraulically setting or hardening, water-containing and during the transport to be subjected to constant movement bulk goods, in particular mortar, concrete, screed or the like.
  • Materials preferably in the form of light, Norm.al and / or Heavy mortar, masonry and / or plastering mortar, various screeds and / or different concretes with a chassis, consisting of a frame and at least one axle, and with a transport and mixing device mounted on the chassis.
  • Transport vehicles are known from the prior art which have a chassis, preferably a truck chassis with a frame and a driver's cab.
  • a rotatingly driven mixing drum is mounted on the frame of the chassis.
  • This mixing drum is essentially elliptical in longitudinal section and has an axis of rotation at one end and a filling and emptying opening at its opposite end.
  • a funnel is arranged in the area of the filling and emptying opening, through which, for example, ready-mixed concrete, mortar or other setting or hardening bulk materials containing water and to be subjected to constant movement during transport are introduced into the mixing drum.
  • the rotation of the mixing drum therefore has in particular the would prevent the bulk material from segregating in the drum.
  • the disadvantage of the vehicles mentioned above is that only bulk goods can be transported. This is particularly disadvantageous when transporting materials of different qualities and properties, since on construction sites different mortars, concretes and / or screeds are sometimes only required in small quantities. As a result, at least two vehicles with different materials must be dispatched to these construction sites.
  • the solution to this problem provides in a generic vehicle for the transport of setting or hardening, water-containing and during the transport to be subjected to constant movement bulk goods that the transport and mixing device in at least two departments for transport with regard to consistency, intended use, place of use or the like different goods is divided.
  • the invention proposes to arrange two departments for goods different in consistency, purpose, place of use or the like on a chassis of a vehicle, such as mortar and the like, so that these goods can be removed separately from the transport departments.

  • a mixing and transport spiral Arranged in the interior of the transport and mixing drum is a mixing and transport spiral which serves both for mixing the filled bulk material and for emptying the bulk material out of the transport and mixing drum.
  • the transport and mixing drums have a size of up to 12 m ⁇ and are mounted under an inclined axis of rotation on standard truck chassis with or without trailing axles or semi-trailers.
  • the coils consist of wear-resistant 6 to 8 mm thick steel sheets, with the transport and mixing drum rotating in opposite directions during filling and emptying.
  • the transport and mixing drum is driven hydraulically by a power take-off from the vehicle engine via a planetary gear, some with an upstream angular gear on the drum journal.

  • such vehicles are also known in which the transport and mixing drum has a separate motor.
  • transport and mixing drums of this type By arranging at least two transport and mixing drums of this type on a truck chassis, it is possible to drive two different bulk goods, for example light mortar and heavy mortar, to a place of use with a single vehicle, so that both light mortar and heavy mortar are used at this point of use can be discharged at the same time.
  • the size of the transport and mixing drums can be coordinated.
  • Known truck chassis can be used to assemble the transport and mixing drums, optionally by extending the frame with a possible trailing axle or as a semi-trailer.

  • both mixing drums have a common filling and emptying opening.
  • the two mixing drums are connected to one another in a rotationally fixed manner and are driven in the same direction of rotation by a common drive.

  • connection of the two nested transport and mixing drums is preferably carried out at their end opposite the filling and emptying opening at which the two mixing drums are bolted or welded to one another, the connection point preferably having a corner-free curved contour which promotes the emptying of the gap space so that materials cannot get stuck.
  • Such training is given, for example, by the fact that the transition between the end of the inner, second mixing drum to the outer, first mixing drum, ie between the outer region of the second mixing drum and the inner surface of the first mixing drum, is designed in the form of an arc of a circle, so that bulk material arranged in this region can be discharged through the emptying device, namely the mixing and conveying helix.
