In its third aspect the present invention provides a method for mixing materials by employing the mixing apparatus of the first aspect of the present invention.
  • cementitious materials are being used for various purposes for the construction of different types of structures, such as buildings.
  • Such cementitious materials may for example be concrete or mortar.
  • Concrete for pouring is a 15 mixture of cement sand/grit and water and stones having a predetermined size.
  • Mortar is a mixture of cement, sand/grit and water.
  • concrete usually is employed for large scale pouring work, such as pouring of a foundation of a building
  • mortar is often used for binding together building materials on a smaller scale, such as for building a brick wall or for plastering a wall.
  • Other materials used for construction work may be tile mortar or adhesives 20 for use with tiles, or rubber granulates admixed with various adhesive products.
  • a common feature of concrete and mortar is that a thorough admixing is required in order to achieve a homogenous mixture and hence the desired strength of the final cured material.

  • Another type of mixing apparatus comprises a stationary container with an upper opening, and which is being suspended on a frame.
  • An electric motor is arranged on the frame and this 30 motor drives one or more agitator arms, which thereby can be brought into rotational movement in the interior of the container.
  • a mixing apparatus which has not been cleaned will not be able to thoroughly mix the materials homogeneously. Herby the concrete/mortar will not attain its intended strength of the concrete/mortar.

  • This lowered position for the holder 6 for the mixing vessel 4 may via the elevation device 16 be changed to a configuration in which the holder 6 for the mixing vessel 4 is in a raised configuration. This is illustrated in Fig. 4a and 4b.
  • Fig. 4a accordingly shows in a perspective view the mixing apparatus of Fig. 1 in a configuration in which the holder 6 for the mixing vessel 4 is in a raised configuration.
  • Fig. 4a also shows details relating to the elevation device.
  • the elevation device comprises a handle 40 which by rotation drives a turning axle 36. This turning axle winds a wire 34 which in its one end is connected to the holder 6 for the mixing vessel 4. Flereby one may, by turning the turning axle 36 via the handle 40, raise the holder 6 for the mixing vessel 4 and thereby also raise the mixing vessel.
  • a safety latch 44 is configured for entering into engagement med a gear 42 which is being arranged on the turning axle 36. Hereby, any return rotation, when the holder is subjected to a weight, can be avoided.
  • the safety latch accordingly also serves for releasing this locking mode in such a way that once the safety latch 44 is being released from the gear 42, the holder 6 for the mixing vessel 4 may be lowered.
  • Fig. 4b illustrates in a perspective view the mixing apparatus corresponding to the one in Fig. 1, this time with the hatch 52 removed.
  • Fig. 4b accordingly shows the mixing apparatus 200 with its shielding 48 except for the hatch 52.
  • the removed hatch defines the opening 54 which provides access to the interior of the mixing vessel.
  • a safety grating 56 covers the opening 54.
  • Fig. 5 is a perspective view illustrating parts of the mixing apparatus of Fig. 1 wherein parts of the shielding 48 for the mixing vessel 4 have been removed.
  • the motor 14 in the form of an electric motor having a gearing device 46 which in combination drives the agitator 10 are seen (in Fig. 5 the agitator 10 with agitator arms 12 are also removed).
  • Fig. 6 is a perspective view illustrating a situation wherein the mixing apparatus 200 of Fig. 1 and 4 after concluded mixing of materials in the mixing vessel 4 are ready for being emptied from the mixing vessel 4 and into a wheelbarrow 300, in that the valve 26 with its valve plate 60 has been brought into its open state, whereby access from the interior 28 of the mixing vessel 4 via the interior 70 of the holder 6 and through the throughgoing opening 24 in the carrier element 8 of the holder is provided.
  • valve plate 64 Pivoting axis of valve plate 66 Lower part of holder for mixing vessel
  • Holder s carrier element in the form of a bottom plate 70 Interior of holder 72 Conical surface or cylindric surface of interior of holder 74 End closure of interior of holder 76 Safety grating for carrier element of holder
