Definitions
- the invention relates to a device according to the preamble of claim 1.
- Such a device is known from DE-A-31 26 086.
- the known device belongs to a stationary system, which is set up in a mortar plant and operated to produce larger batches of ready-mixed mortar, which can be transported to the respective construction site with special vehicles.
- the known device could also be set up on construction sites, e.g. are large construction sites occupied over the long term.
- the known device would have to be delivered disassembled to the construction site and assembled and set up there. After use, the device would then have to be dismantled and transported away.
- the components are conveyed one after the other into the container connected to a scale.
- the scale determines a previously set weight value of the component entered
- the further supply of this component is interrupted by a slide to be closed.
- the screw that continues to run either conveys additional quantities into the container until the conveyor trough is emptied, or the screw that continues to press further material pulled out of the silo against it the slider.
- the invention has for its object, while maintaining and further improving the ease of use and the general advantages of the known device, to design it so that an even more precise dosage is possible.
- the characterizing part of claim 1 By means of the screw conveyors provided thereafter, which are arranged immediately below the storage container which has a vertical division, and the downstream scales, it is possible to install a ready-to-operate system on a construction site in a very short time, which mortar one can deliver exactly the specified composition. Because of the configuration according to the invention, the material storage container, metering device and mixing device form one unit, i.e. they can e.g. can be gripped and loaded and unloaded by a crane vehicle or the like by means of a single hook attachment. Immediately after the device has been set down at the construction site, it is ready for operation, the screw conveyors ensuring reliable forced removal of the individual material components and, in connection with the scale, exact dosing.
- the mixing device is fully integrated into the metering device, which saves space and increases the working speed of the device.
- a computer and control device makes it possible, for example, via a Pre-programmed dosing by simply pressing a button to produce mortar with a desired composition and consistency.
- the design of the scale according to claim 3 ensures a high level of operational reliability even under harsh operating conditions, such as those found on construction sites.
- the force transducer provided according to claim 4 enables a simple conversion of the mechanical deflection of the balance into an electrical signal, which can be further processed to control the device.
- the water supply according to claim 7 enables an equally simple and exact water metering to the free-flowing mixing components.
- the design of the outlet opening according to claim 7 prevents that from the mixing area of the container, soaked mixture is thrown upwards and in this way the conveying area of the screw conveyors becomes clogged.
- the construction according to claim 10 makes it possible to comfortably fill the storage container lying down, that is to say also in the transport position on a vehicle.
- removal and dosing device can be detached from the container makes it possible to deliver a second container to a construction site with the initial delivery, the removal and dosing device being able to be easily implemented after the first container has been emptied to the second container.
- the device according to the invention makes it possible to manage with a single scale, so that the mechanical-electrical conversion devices also only have to be provided in a simple embodiment.
- the device enables premixing already during metering, so that larger material inhomogeneities are avoided from the outset.
- a device according to the invention shown in the drawing comprises a silo-like storage container 1, which in the exemplary embodiment is divided into two partial containers 3, 4 by vertically extending partition walls 2.
- An outlet opening 5, 6 is provided on the underside of each partial container 3, 4.
- a delivery channel 7, 8 is in each case arranged below the outlet opening 5, 6.
- each conveyor channel 7,8 there is a screw conveyor filling it 9, 10, each of which is driven by a shaft 11 or 12 and a motor 13 or 14.
- an outlet opening 16 or 17 is provided in the bottom 15 thereof.
- the outlet openings 16, 17 are covered by self-elastic flaps 18 made of plastic which open downward under pressure.
- the outlet openings 16, 17 open down into a container 19.
- a mixing device 20 is arranged in the container 19, which extends over the entire width of the conveying channels 7, 8.
- the mixing device 20 comprises a plurality of mixing tools which are fastened to a common shaft 21 which is driven by a motor 22 and is mounted in a bearing 23 which is only shown schematically.
- a screw section 25 is provided as a mixing tool in the area of the discharge opening 24 and below the outlet opening 16. This is followed by holding arms 26 attached to the shaft 21 tangentially rotating mixing blades 27, which - as is not shown in the drawing - are set to the axial direction. Finally, in the end region of the container 19, mixing blades 29 are provided, which are attached to the shaft 21 and hold the container 19, via holding arms 28.
- a water line 30 opens into the container 19, which is also shown only schematically and in which an electrically actuated metering valve is arranged.
- the top wall 31 of the container 19 is independent of the bottom 15 of the conveying channels 7, 8, ie there is no fixed connection between the conveying channels 7, 8 and the container 19.
- the container 19 is rather via support arms 32, 33 with the weighing arms 34, 35 connected to a balance 36, which are pivotally mounted in the bearings 37, 38.
- the bearings 37, 38 are attached to the housing cover 39, which is connected to the container 1 at 40.
- the weighing arms 34, 35 press against a force transducer 41, only shown schematically, in which e.g. Strain gauges convert the forces applied by the weight of the container 19 or the material contained therein into electrical signals.
- the device described above is operated in such a way that a certain batch quantity and composition are preselected via the computer and storage device, not shown.
- the one screw conveyor 9 is then first set in motion and at the same time the motor 22 of the mixing device 20.
- a first mortar component e.g. Binder (cement) placed in the container 19 via the conveying channel 7 and the outlet opening 16 and the change in weight recorded on the balance 36. If a predetermined change in weight is reached, the screw conveyor 9 is stopped.
- the mixing device 20 continues to run, axially conveying it away from the outlet opening 16 or the discharge opening 24.
- the metering of a second mortar component e.g. Sand, made via the screw 10.
- the two components are already mixed during the addition of the second component. Even before the first mortar component has been added, water can also be added and mixed in via the water line 30 in a likewise preprogrammed quantity. After a pre-programmed mixing time, the direction of rotation of the motor 22 is reversed and discharged through the discharge opening 24 ready-to-use mortar.
- the overall arrangement is such that the cleaning effort, which is customary in conventional mortar mixing machines, is minimal, since the entire system can be designed to be largely self-cleaning.
