Definitions

  • the invention relates to a charging device for charging a mixer with fluff materials, e.g. with mineral additives.
  • the object of the invention is therefore to provide a loading device with which, on the one hand, takes the time to load a mixer with movable and weighed bulk goods can shorten and on the other hand only a proportionate has a small footprint.
  • this object is achieved by a loading device for loading a mixer with bulk materials, e.g. with mineral aggregates, with two buckets, which are divided by two lifts arranged parallel to each other Winches between their lower ones with controlled flaps or sliders Filling position and their upper tilting position, from which they can be emptied into a mixer, moved and which in their The filling position is supported on each assigned weighing device.
  • a loading device for loading a mixer with bulk materials e.g. with mineral aggregates
  • two buckets which are divided by two lifts arranged parallel to each other Winches between their lower ones with controlled flaps or sliders Filling position and their upper tilting position, from which they can be emptied into a mixer, moved and which in their The filling position is supported on each assigned weighing device.
  • the time for filling can be reduced by the loading device according to the invention of the two buckets considerably shorten because at the same time both buckets with different Bulk goods can be filled, so that there is time to fill both buckets compared to the time for filling only one of all bulk goods Brubels almost halved.
  • each of the two buckets is smaller than one that holds the total measured amount Buckets, the guides of the elevator devices and the winches be interpreted weaker.
  • the two buckets can expediently be used for the purpose of sharing them Connect to each other. With such a connection, fall protection can be provided be created which takes effect when a winch fails or a rope breaks.
  • the mixing device with loading device consists of a bridge, on the bridge for example, a ring trough positive mixer supported on posts 1 3 is arranged, which is provided with a funnel-shaped outlet, over the Outlet connection 4 can be filled, for example, truck mixers.
  • the outlet funnel 5 of a cement silo is located above the mixer 3 the cement can be fed into the hopper. Still located above the mixer 3 a line 6, through which the mixing water is supplied.
  • the additives are poured into the mixer through two buckets 7, 8 which are made of their lower filling position drawn on a guide 9 by winches 10, 11 can be, with curved guides 12 above the mixer 3 for tilting the buckets 7, 8 are provided. They are in their lower position Buckets 7, 8 below a metering table 13, which for each of the radial walls compartment is provided with a controllable metering flap 14. As from the Drawing can be seen, each of the two buckets 7, 8 with three discharge openings controllable metering flaps 14 assigned.
  • Each of the two buckets 7, 8 is supported on its own weighing device, see above that from each discharge opening the amount provided for the respective recipe Aggregates can be deducted.
  • FIG. 3 shows a known loading device with belt scales, in which the by a scraper bucket and over the tip of the cone dumped material on a trigger flap 20 on belt scales 21 the weighed material in the container 22 which is only used for transport promote.
  • the bucket 22 filled with the weighed material is then shown in FIG Wound up and tilted into the mixer 23. 3 shows that the arrangement of belt scales considerably lengthened the system because of the bucket 22 cannot be arranged directly under the exhaust openings 20.
  • a loading device with a weighing container is known. Of the Weighing container 30 is suspended in a pit 31 via weighing cells 32. That too weighing material is fed into the weighing container 30 via the trigger flap 34.
  • the weighing container 30 is provided with a bottom flap 35 through which the bucket 36, which is only used for transport, can be filled.
  • a loading device with weighing container is disadvantageous because it requires a pit, to be able to use the height of the material store sufficiently.
