Definitions

  • the invention relates to a truck mixer, preferably with opposite emptying for building materials, in particular concrete.
  • the truck mixer according to the invention transports a batch of building material in the mixing drum and mixes it on the transport by the rotation of the mixing drum.
  • the building material can also consist of mortar, whereby in addition to masonry mortar and plastering mortar, lime, cement and fireclay mortar can also be considered.
  • these building materials consist of a special dry mix, which in addition to the aggregates or sand and the additives usually contains hydraulic, but occasionally also non-hydraulic cements, and water. As soon as the water comes into contact with the cement, a chemical process begins in most types of cement, the faster the higher the ambient temperature, the faster the ambient temperature one must take into account the heat of hydration released as an additional heat source.
  • the truck mixer according to the invention enables the addition of the mixing water at a time which is more or less shortly before the use of the building material at the construction site during the journey or at the place of use of the building material, because of the deliberately mixing effect which circulates the building material batch, so that the truck mixer is transporting the dry mixture and can mix them with the mixing water.
  • the design of the mixing drum in which the truck mixer according to the invention transports the building material, ensures, because of the firmly arranged, spiral-shaped elevations on the inner wall of the mixing drum, a simple structure of this device which, depending on the direction of rotation of the mixing tower, pulls the building material around its central axis or through it closed mixing drum bottom opposite mixing drum opening to the outside.
  • the invention relates, inter alia, to mixing drums which are constructed so inclined on mostly road-going vehicles designed as trucks or as truck trailers that their opening through which the building material is given or given is above and its closed bottom is below. According to the invention, if the building material has to be transported through narrow cross sections, such as occur, for example, in tunnel construction, the mixing drum also installed with a horizontal arrangement, for example on a rail chassis of the mixing drum axis.
  • the jacket of the mixing drum between the mixing drum base closed with a removable cover and the mixing drum opening can have a number of side-by-side manholes depending on the length and the mixing drum diameter, through which the batch of building material is filled, which emerges through the base with the lid open;
  • the opening of the mixing drum is often used to pick up the building material from an upstream mixing drum and to pass it through a downstream mixing drum.
  • a helical elevation mostly consisting of flat steel is provided above the drum base. It exerts a driving effect on the building material, which leads to strong compaction in the core of the building material batch surrounded by the elevations, which core has been filled into the mixing drum for transport.
  • the mixing effect is prevented, particularly in the case of earth-moist concrete, which leads to considerable deterioration of the building material.
  • These mixing blades are intended to generate a radial and axial flow of the building material in the compacted building material core described.
  • Such a device actually improves the mixing effect and thereby also enables the dry transport of building materials and the addition of the mixing water outside the mixing systems from which the building material is fed to the truck mixers.
  • truck mixers designed in this way have proven to be extraordinarily complex constructions, either because of that to certain ones Truck mixers, such as the truck mixers described, cannot be used for tunnel construction at all or, because of their complicated structure, create numerous sources of interference and are accordingly difficult to maintain.
  • the mixing effect is also unsatisfactory. Because the building material, especially if it is realized with concrete, contains coarse aggregates to a greater or lesser extent, the tools of the compulsory mixer must be protected from being damaged by jammed components of the building material mixture. This can only be achieved if a correspondingly large space is maintained between the compulsory mixing device and the elevations of the drum shell, in which the coarse components can escape, but in which, on the other hand, no compulsory mixing effect is achieved.
  • the invention is based on the object, for a truck mixer of the type known from the document mentioned in a simple manner a general, i.e. to create a structure applicable to the different types of truck mixer described, which ensures complete mixing and movement of the batch of building material through the mixing drum, even in the case of earth-moist concrete, and thereby ensures sufficient mixing.
  • a stream of the building material mixture directed towards the closed mixing drum base is actually generated in an outer jacket area of the building material batch, which stream reverses inward over the mixing drum base and in the core of the building material mixture enclosed by the elevations of the mixing drum jacket Direction towards the mixing drum opening.
  • This counter-current movement of the part of the building material batch described by the mixing drum receives its energy from the flat profiles of the concentrically inner counter-current spirals due to their opposite slope to the mixing spirals which are attached to the drum shell.
  • the overall structure of the new truck mixer is also no longer complicated, but on the other hand also offers the possibility of using this truck mixer structure on flat-lying mixing drums, as is the case with the truck mixers described for tunnel construction must be used.
  • the countercurrent spiral produces not only an axial, but also a radial movement component, because this movement is practically not hindered by the built-in parts. These are nevertheless sufficient to fix the countercurrent spiral in the mixing drum so that it is carried along by it against the resistance of the building material mass and is not deformed in the process.
  • the design of their mixer drum ensures that the truck mixers according to the invention have a mixing effect which was previously only achievable with stationary mixing machines, although one does not need to realize their large dimensions in relation to the contents, nor additional drives, as are the rule with compulsory mixers.
  • the filling quantity of the truck mixers according to the invention essentially corresponds to the filling quantity of conventional truck mixers of the same dimensions. Nevertheless, according to the invention it is prevented that the building material mass in the area of the mixing drum casing only moves around the axis of the mixing drum when the mixing drum is running.
  • the invention has the advantage, even when the mixing drum is full, that the truck mixer can be used as a mixing machine; That is why truck mixers according to the invention eliminate the adverse effects of extreme outside temperatures on the quality of the building material in that only the dry mixture of the building material can be transported, which is then mixed and mixed with the mixing water shortly before use.
  • the conveying capacity of the counterflow spirals is preferably set up in such a way that an axial speed results in the core of the building material mass, which corresponds approximately to the speed which the mixing spirals in the jacket of the building material mass produce in the opposite direction.
  • nozzles for dispensing mixing water are arranged inside the mixing drum, which are connected via pipes to one another and to a pump arranged outside the drum, the nozzles being directed so that their openings lie in the mixed flow shadow during the mixing process of the drum. This ensures good mixing of the building material batch on the one hand and, on the other hand, a uniform distribution and mixing of the building material batch with the mixing water.
  • the pipelines follow the course of the flat profiles and each end in a straight pipe section running in a plane perpendicular to the longitudinal axis of the drum, one of the pipe sections being connected to a supply line connected via a Rotary lead-through in one of the drum ends leads to the pump.
  • nozzles To protect the nozzles from the abrasive building material and as a further additional measure to prevent the nozzles from becoming blocked, they are covered with hollow-shaped caps made of elastic or elastomeric material, in which slit-shaped openings are provided, and which are wear-resistant due to their material.
  • a modified embodiment of the invention provides that nozzles for the mixing water are provided on the end faces of the mixing spirals facing the center of the drum.
  • the countercurrent spirals have been dispensed with in this embodiment.
  • a further modification of the invention provides that the rotating union has several channels, each channel being supplied with mixing water by a pump and behind the rotating union the channels are connected via individual lines to certain discharge nozzles. Depending on the shape, size and construction of the mixing drum, this makes it possible to add water in a targeted or forced manner.
  • the truck mixer can be designed so that the mixing drum is shifted obliquely rising with the bottom and opening above on the chassis of a transport vehicle, but it is also provided that the mixing drum is moved horizontally on the chassis of a vehicle and the mixing drum bottom and the Mixing drum opening can be closed with lids.
  • Truck mixers of this type are used in particular when concreting tunnels.
  • the truck mixers are coupled either long or short.
  • the long coupling creates a distance between the end faces of the mixing drums mounted on the vehicles, which ensures that the train can negotiate curves.
  • the feed and discharge openings which are aligned with one another in the longitudinal direction of the train, mesh with one another, so that the concrete can be discharged from one mixing drum into the other on site if the mixing drums rotate in the appropriate direction.
  • the train is emptied in a continuous manner by the elevations arranged on the inside of the drum driving the building material through the discharge openings.
  • the building material is filled in outside the tunnel.
  • a further feature of the invention provides that the filling opening is arranged in the end wall of the drum opposite the discharge-side drum end wall, to which a filling funnel can be fastened which extends into the filling opening with a chute.
  • the mixing drum When the piles reach the manhole openings, they first have to be closed, then the mixing drum has to be rotated so that there is a uniform, low filling level.
  • the mixer vehicle must be maneuvered under the mixing system so that every manhole opening can be used to fill the building material. All of this results in a considerable amount of time and poor building material quality when filling the mixing drum.
  • a further feature of the invention provides that the filling funnel with cone-shaped lugs arranged on it can be locked in two or more cone-shaped sleeves, which are on the chassis of the vehicle are arranged.
  • the hopper only needs to be inserted into the sleeve and can be easily removed after the filling process. Lengthy assembly is not necessary. Nevertheless, the hopper is safely moved.
  • 1 denotes a pear-shaped mixing drum, which has a closed bottom and an opening 3 opposite the bottom 2, which has no cover and is therefore kept open at all times.
  • the axis of symmetry 4 of the mixing drum shows that it is installed at an incline, the direction of rotation of the mixing drum being indicated by arrow 5.

  • two mixing spirals 11 and 12 are attached on the inside 9 of the drum casing.
  • the attachment of the mixing spirals is designed so that the mixing spirals are taken along when the drum rotates in the direction of arrow 5 against the resistance of a building material mass 13.
  • the two mixing spirals 11, 12, which are offset by a semicircle, have the same pitch and, generally speaking, represent elevations on the drum shell 9, which protrude into the interior 14 of the drum. If such a mixing drum is constructed on a truck chassis 14 'as shown in FIG. 2, it generally has a capacity of between 2.5 and 10 m 3.
  • a hydraulic drive motor 15 which is fed by a built-in pressure generator 16, via a gear 17.
  • the gear 17 acts on the drum base 2 via a flange 18.
  • the rest of the mixing drum rests with a race 19 fastened on the outside of its casing in the region of the neck 8 in a bearing 20 which is arranged so as to be fixed to the structure.
  • a filling funnel 21 In front of the mixing drum opening there is a filling funnel 21 through which a building material mixture can be filled into the drum 1.
  • the mixing drum 1 is driven counter to the direction of the arrow 5 in FIG. 1, the building material is discharged and reaches the prefill container 23 via a chute 22, for example.
  • the two mixing spirals 11, 12 fastened on the inside 9 of the drum casing 10 are designed as solid wall spirals. If the building material mixture is poured into the drum via the filling funnel 21, it must be rotated in the direction of arrow 5 so that the mixing spirals 11, 12 can move the building material mixture into the interior 14 of the drum. In the embodiment according to FIG. 1, this process is favored by the inclined mounting of the mixing drum. For reasons of economy, the volume of the drum is always fully utilized.
  • the filling line 24 of the drum then runs from the lower edge 25 of the outlet opening at an incline of approximately 25 degrees to the upper inside of the mixing drum. Behind or below this filling line 24 is the drum bin to the head end, i.e. bulging in the direction of the drum testicles 2.
  • the motor 15 rotates the mixing drum in the direction of the arrow while the vehicle 14 'is traveling at low speed.
  • two flat profiles which are curved according to helical lines about the mixing drum axis 4 are fastened for entrainment when the mixing drum rotates, as shown in FIGS. 1 to 5.
  • These flat profiles start from the mixing drum base 2 and end in front of the mixing spirals 11, 12 and the mixing drum opening 3. They are designed in the opposite direction to the mixing spirals 11, 12 and are arranged offset by a semicircle such that they act as counter-current spirals 26, 27.
  • the solid wall spirals 11, 12 take the building material mixture against the direction of the arrows 33, 34 and convey it through the opening 3 to the outside.
  • the material to be mixed slides off the counter-current spirals 26, 27 until the building material core is dissolved, the mass of which is also grasped by the solid-walled spirals 11, 12 and transported to the outlet opening 3.
  • the countercurrent spirals 26, 27 have the same slope as the mixing spirals 11, 12. Furthermore, the width of the flat profiles forming the counterflow spirals 26, 27 is less than the width of the elevations on the mixing drum wall 9 formed by the mixing spirals 11, 12.
