Definitions

  • the invention relates to the field of civil engineering. It relates to a self-propelled combined concrete compulsory mixer, which is particularly suitable for use in road and paving.
  • a disadvantage of such mobile bowl mixer is that they must unload their entire load once they are on site, and that this must be done during a relatively short period of time. This is not practical for users of concrete mixes which are less than the given one Require mixer allocation size and / or require the delivery of smaller quantities of concrete over a longer period of time.
  • Another disadvantage of these known concrete mixers is the large footprint.
  • a vehicle that operates as a mobile metering and mixing device to provide varying amounts of premixed concrete when needed.
  • a cement bunker is arranged on the chassis of a truck in a vertical position.
  • cement aggregates and water are supplied to a screw conveyor arranged obliquely on the truck via various conveyors, in which the materials are then mixed into concrete.
  • the concrete is removed and processed directly on site at the construction site.
  • the aim of the invention is to avoid the disadvantages of the prior art mentioned above.
  • the invention is based on the object to develop a mobile combined concrete mixer, which is able to produce a good quality fresh concrete in humid conditions directly on the site and distributed linearly. It should require little space and be manageable without major maneuvering, the proper exact distribution of the concrete should be guaranteed within a very short time.
  • the advantages of the concrete compulsory mixer according to the invention are that the concrete can be mixed on site, ie within the construction site, efficiently by means of the vertical compulsory mixer and distributed linearly over the conveyor belt.
  • the conveyor belt causes a regular delivery of the Concrete, which can not be achieved by slipping or similar known devices.
  • the driving speed also determines the amount of work to be done by the worker per meter, so that the laborious distribution by hand is eliminated.
  • the concrete compulsory mixer according to the invention is particularly advantageous if only one lane is available.
  • the self-loading device has at least one return spring, by means of which the provision of the self-loading device from the vertical position takes place when dumping in the compulsory mixer.
  • a hydraulic control circuit for controlling the loading shovel of the self-loading device suffices here.
  • the fixed under the compulsory mixer conveyor belt projecting laterally under the compulsory mixer in the use position in the direction of travel and its altitude is easily fixed by means of an adjustable chain, while it is in non-use position, for example, during transport, in the vertical folding is. Then advantageously little space is needed.
  • the concrete compulsory mixer consists of a combination of commercially available individual devices.
  • Fig. 1 the inventive self-propelled combined concrete compulsory mixer 1 is shown completely in a side view
  • Fig. 2 shows a section along the line II-II.
  • the concrete compulsory mixer 1 is a combined device, which consists essentially of a self-propelled carrier vehicle 2, an actual compulsory mixer 3 arranged in a not visible in Fig. 1, but visible in Fig. 2 vertical mixer axis 4 means for mixing 5 of the starting / aggregates the concrete to be produced, as well as a self-loading device 6 and a conveyor belt 7.
  • the carrier vehicle 2 is equipped with four-wheel drive.
  • the carrier vehicle 2 is an articulated steering, z.
  • the compulsory mixer 3 On the chassis 8 of the carrier vehicle 2, the compulsory mixer 3 is mounted with a vertical mixer axis 4 and fixedly mounted.
  • the mixing means 5, for example an agitator, are set into rotary motion, thereby mixing the starting materials / aggregates and ultimately producing the ready-to-use concrete.
  • the binder (cement) and the aggregate water are added directly to the mixing bowl.
  • the mixing bowl is covered with a sturdy grid (not shown in the figures), which has a mesh size of about 50 - 70 mm, and crosswise provided with tooth rails.
  • a sturdy grid not shown in the figures
  • tooth rails As a result, on the one hand unintentional reaching into the stirring device is prevented.
  • the bagged goods can be torn open on the toothed rails, the cement falls through the grid in the mixing bowl, while the paper bag remains on the grid and can be removed without danger.
  • This is mounted either directly on the compulsory mixer 3 or on the chassis 8 of the carrier vehicle 2.
  • it is mounted on the chassis 8 of the dumper, namely on the front in the direction of travel part of the chassis, ie at the opposite end of the cab 11.
  • the self-loading device 6 is operated by a further separate hydraulic control circuit. It is designed so that a single hydraulic control circuit is sufficient to control the loading bucket.
  • the compulsory mixer 3 has on its underside an example, by means of a slide closable discharge opening 10. If necessary, this discharge opening 10 is opened and the compulsory mixer 3 is emptied via the arranged below the discharge opening 10 in the lateral direction to the direction of conveyor belt 7. This allows exact metering and accurate distribution of the concrete at the construction site.
  • the conveyor belt 7 is also hydraulically driven by its own control circuit.
  • the conveyor belt 7 is hinged under the discharge gate / discharge opening 10. It can be folded completely into the vertical during transport, so that the mobile concrete mixer 1 requires only little space. When applying the concrete, the height of the conveyor belt 7 is fixed with an adjustable chain 12.
  • Fig. 3 shows schematically the use of the concrete compulsory mixer 1 according to the invention in the production of linear structures, such. B. edging from curbs. This requires a Produce the concrete to meet the quality requirements and distribute linear according to the course of the edging.
  • the vehicle picks up the aggregates within the construction site with the self-loading device 6 and mixes the concrete. It brings the finished concrete to the building and distributes it via the conveyor belt 7.
  • the conveyor belt 7 causes a regular output of the concrete, which can not be achieved by slipping or similar devices. By the driving speed of the worker determines the amount of concrete organric density, thereby eliminating the tedious dispensing by hand.
  • the self-propelled concrete compulsory mixer 1 is particularly advantageous if, as shown in Fig. 3, only one lane is available. On the left in Fig. 3 is denoted by 13 the finished offset edge enclosure, which delimits the lane for single-lane traffic 14 from the left sidewalk. Right in Fig. 3, the lane for the construction site traffic 15 is shown, on which the edge enclosure for the right sidewalk is built by means of the mobile combined concrete mixer 1 according to the invention.
  • the mobile concrete mixer 1 according to the invention is able to produce good quality fresh concrete in earth-moist condition directly on the construction site and distributed linearly.
  • This device is particularly suitable for use in road and paving, z. B. for the production of edge borders, smaller retaining walls and the like.
  • the combination with the very agile, powerful carrier vehicle 2 and the conveyor belt 7 allows a fast and accurate distribution of ready-to-use concrete. Since the vehicle always runs parallel to the distribution direction, the space required is relatively small.
