Definitions

  • the invention relates to a material feed container for receiving and removal of flowable and / or pumpable conveyed goods with two opposing, converging towards a container bottom in a funnel-like manner Sidewalls.
  • Material feed containers of this type are used, for example, in mortar spray machines for receiving the in a mixer of powdered mortar and Water-based liquid mortar used by the material feed tank from, for example, a conveyor spiral and a screw conveyor is promoted to an office.
  • Mortar sprayers are mostly called Motor vehicle trailers trained mobile machines with their own Drive motor and compressor are equipped.
  • To the transport weight to keep small, u.a. in the construction of the material feed container paid attention to a light construction.
  • heavy material to be formed dimensionally stable must, were previously compromises in the selection of the container wall thickness required. In order to get thinner wall thicknesses, it was previously suggested the container walls on the outside with welded reinforcement strips to provide. However, it had to be accepted that occurs during welding delay, the subsequent straightening had to be fixed again.
  • the invention is based on the object, a container construction to develop the use of thin-walled container walls allowed and still ensures high rigidity.
  • the solution according to the invention is based primarily on the idea that the two opposite, converging funnel-like towards the container Side walls of the material feed container in their course in Direction tank bottom at least partially convex to the container interior are curved.
  • the inherent rigidity significantly increased.
  • the wall thickness can be reduced compared to flat side walls.
  • the inventive Solution also causes the wall slope of the increases both side walls towards the container bottom. This leads to a Improvement of the sliding behavior of the material in the container towards the bottom of the container.
  • the two side walls are functional over the container bottom concavely curved after the container interior with each other connected.
  • the two side walls to form an im Cross-section of rectangular outline bounded by two end walls.
  • the two outer edges of the end walls have a to the Curvature of the side walls adapted concave curvature.
  • a further preferred embodiment of the invention provides that in the field the container bottom is at least over part of the floor length between the two end walls extending mixing and / or Conveyor is arranged.
  • the mixing and / or conveying member is included expediently designed as a conveyor spiral.
  • the pump organ can be used as a screw pump, Be configured piston pump or rotor pump.
  • the mobile mortar spraying machine shown in Fig. 1 in a front view is designed as a motor vehicle trailer. It has a single-axle chassis 10 with trailer drawbar 12 and telescopic support leg 14, the one located in an engine compartment 16 drive motor with compressor and Machine control, a material feed container 18 and a as Hubmischer trained mixing container 20 carries.
  • the mixing container 20 is via a filling opening in the region of its lid 22 with powdered Mortar loadable. It also includes a water connection 24 for the controlled supply of water and an unillustrated mixer for the production of pumpable wet mortar.
  • the wet mortar is going down its completion by tilting the mixing container 20 about the axis 26th transferred to the material feed container 18 and from there via the im Bottom area of the material feed container 18 arranged conveyor spiral 28 and the outwardly subsequent screw pump 30 via a Hose conveyed to a job site.
  • a special feature of the invention is that the two side walls 32 of the material feed container 18, in the direction of the container bottom 34th converge, over most of their height one after the container interior have pointing convex curvature. With this measure will ensures that the inherent rigidity of the side walls 32 for a given wall thickness is significantly increased. Conversely, given a given rigidity the wall thickness compared to the use of flat side walls be reduced, resulting in a significant weight savings. How out Fig. 3 can be seen, takes the wall slope in the region of the side walls 32 in the direction of the container bottom 34 too. This will cause the material to slip off facilitated in the direction of conveyor spiral.
  • the two side walls 32 through two vertical flat end walls 36 limited.
  • the front side walls 36 are at their downwardly facing marginal edges 38 in the same way as the side walls 32 concavely curved.
  • the motor-driven drive shaft 40 for the conveyor coil 28 and the screw pump 30 is connected.
  • the invention relates to a material supply container for receiving and discharge of flow and / or pumpable material.
  • Material feed container 18 of this type For example, in mortar sprayers for receiving previously in used a mixer 20 wet mortar.
  • the material feed container 18 has two opposite, to a container bottom 34 towards funnel-like converging side walls 32, over which the Mixture to a arranged in the bottom area mixing and conveying member is directed.
  • the two funnel-like side walls 32 in their course in the direction of the container bottom 34 at least partially the container interior are curved convex, so that their wall slope in Towards the container bottom 34 increases.
