Definitions

  • the invention relates to a mixing device according to the preamble of claim 1.
  • a mixing device of the type required in the preamble of claim 1 is known from DE-B-21 10 047. It enables inexpensive mixing without the need for large vertical relative movements between the mixing container and the mixing tool in order to produce and cancel the mixing position.
  • a lifting device is required in order to connect the first container part, which is designed to be transportable, to the second container part, which is pivotably mounted on the stationary holder. Furthermore, since the second container part with the drive motor for the agitator carried by it has to be pivoted, if necessary, even without the first container part or when the mixing container is not full, whereby a considerable torque must be applied by the drive motor arranged far outside the pivot axis, the pivot drive must known execution are undesirably large.
  • the invention is therefore based on the object of designing a mixing device of the type required in the preamble of claim 1 in such a way that a lifting device for the transportable first container part can be dispensed with and the pivot drive for the mixing container can be dimensioned substantially smaller.
  • the second container part can be raised and lowered with respect to the pivot axis by means of a lifting device according to the invention, a separate lifting device for the transportable first container part can be dispensed with.
  • the second container part is lowered onto the latter and then raised in order to be pivoted into the mixed position.
  • the second container part and the drive motor for the agitator carried by it can be raised and lowered with respect to the pivot axis, it is possible to shift the center of gravity of the pivotable parts before pivoting movement so that it coincides with the pivot axis.
  • the second container part with the drive motor carried by it can also be pivoted with a low torque - if, for example, the second container part is to be pivoted without the first container part for cleaning purposes or if a pivoting movement of the complete, but not or only slightly filled mixing container is required.
  • the required pivot drive can be dimensioned very small and inexpensive.
  • a stationary holder 1 in which a pivot shaft 2 is pivotably mounted by means of a handle 3 (instead of the handle 3, a motorized pivoting device can of course also be provided).
  • the first container part 5 is raised so far that it can be connected to the second container part 6 pivoted into the position according to FIG.
  • the mixing container 4 can then be pivoted into the mixing position according to FIG. 2 by means of the swivel shaft 2, the second container part 6 now forming the bottom of the mixing container and an intensive mixing movement taking place inside the mixing container 4 by means of the agitator 8. After the mixing process has ended, the mixing container 4 is pivoted back into the position shown in FIG. The transportable first container part 5 can then be removed and with the finished mix on the! Dolly 10 are removed.
  • the pivot shaft 2 is mounted in the fixed holder 1 by means of bearings 13.
  • the drive provided for motorized or manual actuation of the pivot shaft 2 (in FIG. 4 on the right side of the holder 1) is not shown.
  • a vertically arranged support plate 15 is firmly connected on the side of the fixed holder 1 facing the mixing container (a second such support plate 15 is of course also present on the other side of the divided mixer shaft 2; for that Understanding the invention is sufficient to describe the right half of the mixing device, which is schematically illustrated in FIG. 3).
  • a lifting device which consists of two hydraulic cylinders 16, 17 arranged on different sides of the pivot shaft 2. These hydraulic cylinders are fastened to the support plate 15 by means of claws 18 and screws 19.
  • the support plate 15 carries two guide rods 20, 21 which are arranged parallel to one another in a vertical plane.
  • the second container part 6 is fixedly connected to an upper guide plate 22 and a lower guide plate 23. These two guide plates 22, 23 are guided on the guide rods 20, 21 and can be equipped with sliding bushes 24 for this purpose.
  • the second container part 6 can therefore be lowered and then raised in order to be pivoted into the mixed position.
  • the lowest position of the second container part 6 is generally expedient when the first container part 5 is removed, when the pivotable second container part 6 with the drive motor 9 carried by it is pivoted in the most balanced position for cleaning purposes, for example by 90 ° (ie in an approximately horizontal position) should.
  • An intermediate position of the second container part 6 results when it is to be lowered onto a lower container part 5 to be coupled.
  • FIG. 6 shows a further exemplary embodiment of the invention, in which the second container part 6 is raised and lowered by an electric motor 30 (slip-on geared motor).
  • the electric motor 30 acts on a horizontally arranged threaded spindle 31, which is in engagement with two threaded spindles 34, 35 via a bevel gear 32 and 33, respectively.
  • the second container part 6 is raised and lowered via these threaded spindles.
  • guide rods 20 ', 21' are provided, which are arranged on a support plate 15 '.
  • the stand of the mixing device is designated 36. It carries a motor 37 by means of which the mixing container pivots about the horizontal pivot axis 14.
  • a first device (not illustrated in detail) is expediently provided, which responds when the torque generated by the first and / or second container part 5 or 6 about the pivot axis 14 exceeds a certain value and then the lifting device (ie the electric motor 30) operated in the sense of reducing this torque.
  • a second device is also provided which interrupts the further pivoting movement of the first and / or second container part 5 or 6 until the torque generated by the first and / or second container part about the pivot axis 14 when the said first device responds a predetermined minimum value is reduced.
  • the lifting device expediently lowers the mixing container only when an approximately vertical position is reached in order to keep the otherwise increasing torque low. In this way, the lifting device is not only used for lifting and lowering the second container part, but also for weight or. Torque compensation used.
  • drive motor 9 of the agitator is attached to the pivotable mixing container in the exemplary embodiments explained, a stationary drive motor can be used within the scope of the invention.
