Definitions

  • the invention relates to a device for loading a mixing tank with bulk material, especially with building materials, such as sand, gravel, cement and / or fine concrete, with a machine frame supporting the mixing kettle, with one on the mixing vessel, facing upwards, preferably pressure-tight by means of a sealing cover lockable loading opening and with a Machine frame around a horizontal frame Swivel axis between a lowered filling position and a raised emptying position with hydraulic or motor means limited pivotable, a Filling opening and one to the boiler-side loading opening pointing, in the raised emptying position in this opening having funnel-shaped emptying opening Loading bucket.
  • building materials such as sand, gravel, cement and / or fine concrete
  • Feeding devices of this type are mainly used for compressed air conveyors for building materials used a mixing and pressure vessel with a have relatively small fill opening into which the Loading bucket in the raised emptying position with its funnel-shaped emptying opening immediately flows into.
  • the mixing kettle is placed over its filling opening with cement, sand and water in a given Quantity ratio loaded.
  • the mixture is made after Mixing with the filling opening closed under the influence of compressed air to an external processing point promoted.
  • the filler opening on the boiler side is relatively small due to its design. It is therefore quite difficult to get the bulk from the loading bucket practice loss-free in the mixing bowl, because a sufficiently sensitive dosage of the material flow not possible by changing the angle of repose is.
  • both sand and cement over the loading bucket is fed to the boiler.
  • the loading bucket has a tear-open edge for this purpose for cement bags. If not in such a case all the material from the loading bucket into the Mixing kettle is passed, there is a risk that it incorrect dosing comes from either too much cement or too much sand from the loading bucket gets into the boiler. Added to that is that when it is wet Weather or in the rain, caking of cement and sand can come in the feed bucket gradually to solid deposits and malfunctions being able to lead. To avoid this, it is desirable the cement is not added via the feed bucket, but directly into the mixing kettle.
  • the boiler-side loading opening is suitable however, because of the limited opening width and a missing tear-open device for the cement bags Not.
  • the invention is based on the object a loading device of the type specified Way to develop with a flawless dosage of the bulk goods without the risk of overflowing can be achieved.
  • the solution according to the invention is based on the idea that by using an additional to the Tipping axis of the loading bucket or around a parallel one Axis opposite the machine frame and the loading bucket feed hopper with limited pivoting capacity, the one facing the bucket-side emptying opening Inlet opening and one of the boiler-side Filling opening facing outlet opening, rapid and clean emptying of the loading bucket is possible in the mixing tank and that further mixture components, like cement, glass fiber and water, with the loading bucket lifted over the hopper can be metered into the boiler.
  • a preferred embodiment of the invention provides that the hopper with the loading bucket over a connecting element is coupled so that in the raised Emptying of the loading bucket Emptying opening of the loading bucket immediately in the inlet opening of the hopper and the outlet opening the hopper directly into the boiler-side loading opening that opens into a Intermediate position of the loading bucket from the inlet opening the with its outlet opening in the loading hopper opening on the boiler side is lifted and that in the lowered filling position the hopper of the feed hopper with release of the boiler-side loading opening is lifted off the mixing kettle.
  • This sequence of movements is made possible with particularly simple means by that the hopper has a flexible or limp connection element, for example via a rope or chain with the loading bucket connected is.
  • the hopper is useful between a boiler end stop and a bucket-side end stop swiveling, the filling funnel under the influence of its own weight against the preferably rubber-buffered end stops is present.
  • the hopper When tilting the loading part in one or other direction, the hopper is appropriate under the influence of the connecting element or the loading bucket against him over a top dead center pivoted.
  • the lifting funnel from the boiler-side loading opening takes place when the loading bucket is tipped down the intermediate position from under the influence of the connecting element.
  • the addition of cement can loading bucket in the intermediate position directly through the hopper.
  • the funnel can do this with one towards Tear-open edge for cement bags be provided.
  • the intermediate position of the Loading bucket selected so that it is in the loading bucket already located bulk goods Angle of repose that leads to partial emptying in leads the mixing kettle. It is important for this that the loading container with its emptying opening in the one that leaves the inlet opening of the hopper free Intermediate position opens into the hopper.
  • Another advantageous embodiment of the invention stipulates that the closure cover to a common Tilting and swiveling axis of the loading bucket and of the hopper are fixed to the frame Folding axis is pivotable.
  • the compressed air conveyor shown in the drawing exists essentially from a single-axle chassis 10, on which a compressor 12, a mixing tank 14 and a feed device assigned to the mixing vessel 14 16 is arranged for bulk material.
  • the chassis 10 is with two support legs on the mixing tank side 20 supported on the floor 22.
  • the mixing kettle 14 is on its upper side with a loading opening 24 provided with a sealing cover 26 for mixing and conveying purposes can be closed in a pressure-tight manner.
  • the mixing bowl 14 with sand, gravel, cement or fine concrete serves the feed device 16, the one around a frame-fixed tilt axis 28 by means of a Hydraulic cylinder 30 pivotable on the chassis 10
  • Loading bucket 32 and one about the tilt axis 28 has pivotable hopper 34.
  • the loading bucket 32 and the hopper 34 are over a slack, oriented transversely to the tilt axis 28 Metal rope 36 connected to each other and therefore lead a coupled tilting and during the loading process Swivel movement.
  • the loading bucket has one Filling opening 38 and one in the direction of the filling funnel 34 having funnel-shaped emptying opening 40 while the filling funnel 34 has an inlet opening on the bucket side 42 and a boiler-side outlet opening 44 having.
  • the cover is during the loading process 26 of the boiler-side loading opening 24 open.
  • the sequence of movements during the loading process is as follows:
  • the loading bucket 32 is shown in FIG. 1 lowered end position via the filling opening 38 by hand with a shovel or scraper filled.
  • the hopper is in this position 34 from the feed opening 24 of the mixing vessel 14 lifted and is under the influence of Gravity against a bucket-side stop 46, while the connecting cable 36 sags.
  • this intermediate position can also contain other additives, such as glass fibers or water is added to the mixing kettle, before the loading bucket is completely in the mixing tank is emptied. Then the loading bucket for complete emptying into its upper end position (Fig. 6) pivoted and, if necessary, by oscillating actuation of the hydraulic cylinder 30 shaken. The connecting part hangs in the upper end position 36 limp through.
  • the invention refers to a device for loading a mixing tank of a compressed air conveyor for thick matter with bulk goods, in particular with building materials, such as Sand, gravel, cement and / or fine concrete.
  • the loading device includes a mixing vessel 14 carrying Chassis 10, an arranged on the mixing vessel, upward-facing, by means of a closure cover 26 pressure-tightly closable loading opening 24 and one on the chassis around a horizontal frame Tilt axis between a lowered filling position and a raised emptying position with hydraulic Means limited pivotable, a fill opening 38 and one to the boiler-side loading opening 24 pointing into the raised emptying position in this opening having funnel-shaped emptying opening 40 Feeding bucket 32.
  • a hopper 34 proposed the about the tilt axis 28 of the loading bucket opposite the chassis 10 and the loading bucket 32 is pivotable to a limited extent and one of the bucket-side emptying opening 40 facing inlet opening 42 and one of the boiler-side loading opening 24 facing outlet opening 44.
