Definitions

  • the invention relates to a mixing machine, in particular a construction mixer, for mixing mixes, in particular for mixing mortar, plaster, screed or concrete, according to the preamble of claim 1, and a method for operating or actuating a mixer for mixing mixes according to the preamble of claim 16.
  • Such mixing machines are generally known, for example from DE 10 2004 014 326 A1 which has a mixing machine with a mixing vessel called a mixing vessel and a drive motor for a mixer arranged in the mixing vessel, the mixing vessel having an upper, closable filling opening for the material to be mixed. Furthermore, a safety device is provided to secure the filling opening against reaching into it while the mixer is running, wherein the safety device can be secured and unlocked with a key element necessary for the operation of the drive motor. Unlocking the filling opening with the key element is therefore only possible when the drive motor is switched off. This means that the key element can either only be used to influence the drive motor, that is to say to switch it on or off, or to influence the safety device. Simultaneous use of the key element on the drive motor and at the security device is excluded. This should reliably avoid reaching into the mixing container while the mixer is running.
  • outlet opening of a mixing container which can regularly be closed by means of a closure element, also forms a further potential risk, in particular when the closure element is in an outlet position that releases the outlet opening.
  • the WO 2013/054308 A2 shows a closure element in the form of a protective cover. When this protective cover is in the open outlet position, the outlet opening is not closed and access to the interior of the container is therefore possible.
  • the U.S. 5,419,633 shows, in connection with a pivotable closure element, a cover by means of a protective grille.
  • the DE 1 280 116 A discloses a mixing machine for mixing mixed material, according to the preamble of claim 1, as well as a method for operating or actuating a mixing machine for mixing mixed material, according to the preamble of claim 16.

  • the at least one closure element (for example a swivel plate, to name just one example) can be displaced between a closure and / or mixed position that closes the at least one outlet opening and an outlet position that releases the at least one outlet opening.

  • the discharge chute is also designed as a displaceable unit which can be displaced between different positions for Example is displaceable between a use position and a cleaning position. This possibility of displacing the discharge chute ensures that it can be transferred or moved into a cleaning position in which the discharge chute can be cleaned accordingly.
  • the discharge chute adjoins the outlet opening in its use position, so that when the closure element is in the outlet position, the mixed material can be discharged from the mixing container via the outlet opening and introduced into the discharge chute.

This can be done in a simple manner.
  • the safety device further has at least one safety element or at least one safety element is assigned to the safety device, by means of which the safety device or at least one component of the safety device is not displaced into the outlet opening when a closure element is in the outlet position shielding position, preferably the displacement of the discharge chute from the basic position to the cleaning position, and by means of the closure element in the closed and / or mixed position, the displacement of the safety device or at least one component of the safety device into which the outlet opening cannot shielding position, preferably the displacement of the discharge chute between the basic and the cleaning position, can be released and / or the displacement of the closure element into the outlet position can be blocked.
  • Such a specific structure ensures in a simple manner that it is always ensured in the most varied of positions of the safety device, preferably an ejection chute as a safety device or as a component of the safety device, and regardless of the position of the closure element (in particular when the closure element is open) that no Intervention can take place from the outside through the outlet opening into the interior of the mixing container.
  • the safety device has a plurality of safety elements which are formed on the discharge chute and on the closure element and / or assigned to them and can be brought into different operative connections or are in different operative connections in the different positions of the closure element and / or in the different positions of the discharge chute on.
