Definitions

  • the invention relates to a device for mixing and pumping a mortar, in which an elongated mixing conveyor unit in a row in the direction of a longitudinal axis has a drive device, a mixing device and a pump device, in which a mixing housing of the mixing device laterally forms an inlet opening inclined to the longitudinal axis, which is surrounded by a flange for attaching a feed device, in which the feed device is placed on the flange of the mixing housing with a counter flange surrounding an outlet opening and is fixed to the mixing housing by means of an easily operable and releasable coupling device, and in which the feed device is at the top forms an open filler housing, which merges downwards into an angled outlet connection which ends with the outlet opening and the counter flange, the feed device being assigned a closure slide.
  • the filling housing is a tube piece of an adapter which is connected at the top to a silo for building material, at the outlet of which the Locking slide is arranged. There is no additional conveyor to bring the building material from a storage supply into the mixing conveyor unit.
  • the silo is closed by means of the slide valve when the mixing conveyor unit is cleaned and stopped for a work break.
  • This device is tied to the silo for use. The device is practically unsuitable for manual filling because the capacity of the filler housing is small and the upper opening of the filler housing is too small.
  • the device according to the invention is to achieve this object, characterized in that the filling housing is an upwardly widening funnel storage housing, which extends upwards beyond the lower quarter of the drive device, and the closure slide is arranged at the outlet connection of the funnel storage housing.
  • the funnel storage housing can be filled by hand because of the large opening at the top and is designed so that it can accommodate a sufficiently large supply of building material in order to be able to carry out several operations that are separated from one another with the device.
  • This is not a fixed funnel-shaped attachment, but a detachably coupled, large funnel storage housing.
  • the hopper storage housing is locked against the mixing housing by means of the slide lock.
  • the device according to the invention allows the mixed conveying unit to be used optionally in a changeable manner with manual filling, with work breaks and with a supply of building material for several work steps, without an additional mechanical conveying device being provided between the building material storage supply and the mixed conveying unit. It can be bagged by hand in the hopper housing or pour into the storage container.
  • the mixing conveyor unit is arranged with its longitudinal axis inclined relative to a vertical, as a result of which the funnel storage housing seated on this mixing conveyor unit is arranged more favorably.
  • the hopper storage housing is arranged on the side next to the upper part of the mixing conveyor unit.
  • the building material is e.g. based on gypsum, cement or lime and is mixed with the mortar in the mixing conveyor unit with water.
  • the device is relatively handy and relatively small. There is no additional conveyor device to bring the building material from a storage supply into the mixing conveyor unit.
  • closure slide is arranged outside the funnel storage housing and the outlet connection when in the open position and these are provided with an opening through which the closure slide passes in order to reach the locked position. It is very expensive to counter such a breakthrough to prevent the leakage of building material. The building material also cakes slightly at the contact areas of the slide gate when the breakthrough occurs.
  • closure slide is arranged in the funnel storage housing, is displaceably guided on an inclined wall of the funnel storage housing, and crosses the outlet connection in a blocking position in the blocking position.
  • the slide valve is completely provided in the funnel storage housing and / or the outlet connection and openings for a passage of the slide valve are avoided. Actuating means engaging on the slide valve can be easily and reliably guided out of the funnel storage housing.
  • the mixing housing has a laterally projecting pin on each of two opposing sides and if a hook attached to the hopper storage housing is pushed over each pin from above and a screw connection of the flange and counterflange is provided.
  • This type of easily releasable fixing or attachment of the hopper storage housing takes into account the fact that the mixing conveyor unit is mounted in a stationary manner for the attachment and that the funnel storage housing, which is lighter in comparison, is moved.
  • the screw connection prevents access to the inlet opening of the mixing housing.
  • the funnel storage housing is supported toward the upper end against the drive device.
  • the drive device in operation makes a wobble movement a low amplitude per se, which increases upwards. This wobble movement is transmitted to the funnel storage housing and causes it to vibrate. The vibration of the hopper storage housing promotes the flow of the building material into the mixing device.
  • the drive device has outlet openings for cooling air on the side facing the filling housing and if the wall of the funnel storage housing facing the drive device projects upward toward the upper end piece of the drive device.
  • This wall of the funnel storage housing which is elongated upwards, prevents cooling air that leaves the drive device from blowing into the funnel storage housing and blowing up building material located there.
  • the funnel storage housing is provided on the inside, at the bottom, at the transition to the outlet connection, with a transverse grating. This grid prevents manual access through the connection piece into the mixing device.
  • a particularly expedient and advantageous embodiment is present when the mixing housing is provided with radially projecting pieces and when the mixing conveyor unit is attached to a mobile stand frame in a detachable manner by the mixing housing in one side open recess of a cross piece of the stand frame is arranged and the projecting pieces are supported on the stand frame cross piece from above.
  • the mixing conveyor unit is easily detachably attached to the mobile stand frame without anything being changed on the mixing conveyor unit.
  • the generally obliquely inclined arrangement of the mixing conveyor unit is given by the hanging in the case of a correspondingly inclined configuration of the cross piece of the stand frame.
  • the mixing housing can also be hooked and screwed in relation to the stand frame crosspiece.
  • the stand frame has a pair of front legs and a pair of rear legs and one leg of one pair and one leg of the other pair are spread apart from each other from the cross piece and if each one of the two against each other spread legs on the cross piece is rotatably mounted and easily detachable and can be placed against the other leg after loosening the fixation. Due to the collapsibility, the stand frame can be reduced in size so that it can be accommodated with reduced space requirements for transport or storage.
  • the device according to the drawing comprises a mixing conveyor unit 1, which comprises a drive device 2, a mixing device 3 and a pump device 4.
  • a feed device 5 is attached to the mixing conveyor device 1 and the mixing conveyor device is attached to a mobile stand frame 6.
  • Flowable building material e.g. powdery gypsum, which comes from this feed device into the mixing device 3. This is supplied with water via a nozzle 7, so that mortar is produced, which is released by the pump device 4 via a nozzle 8.
  • the drive device 2 comprises a drive plate 9 on which a motor 10 is mounted and carries the protective brackets 11 which comprise the motor.
  • the motor 10 is provided with outlet openings 12 for cooling air all around.
  • the mixing device 3 essentially shows a mixing housing 13 towards the outside, which comprises an upper cylindrical region, a middle conical region and a lower tube region.
  • two radially projecting U-brackets 14 are provided on the cylindrical area on two opposite sides.
  • a pin 15 also protrudes laterally, which leads to the feed at the upper end of the cylindrical region device 5 is arranged offset.
  • the cylindrical region of the mixing housing 13 forms a feed 16 towards the feed device 5, which is delimited at the bottom by a flange 17 which surrounds an inlet opening (not shown) which is semicircular.
  • the inlet opening and the flange 17 are inclined relative to the central axis or longitudinal axis of the mixing conveyor unit 1 by an angle of more than 30 °, of approximately 45 ° and fall outwards in the direction of the longitudinal axis. Since the cylindrical region of the mixing housing 13 is round in cross section, the circumference of the inlet opening and the flange 17 run in a semicircular shape, the arc being directed outwards and the chord being moved towards the longitudinal axis.
  • the feed device 5 forms a funnel storage housing 18 which is completely open at the top and is rectangular in cross section.
  • the cross section tapers downwards like a pyramid and merges with the outer or lower wall 19 into a curved shape.
  • This wall 19 thus increasingly forms a curved channel towards the lower end in order to facilitate the flow of the building material from the funnel storage housing 18.
  • a toothed web 20 runs across the funnel storage housing 18 and cuts open paper bags.
  • a transverse grating 23 is provided at the transition from an outlet connection 22.
  • the lower end of the funnel storage housing 18 is located at the cylindrical region of the mixing housing 13 and the funnel storage housing 18 has a rear wall 24 which is raised almost to the upper end of the motor 10. At the top, the rear wall 24 carries a support piece 25 which is designed as an adjusting screw and which bears against one of the protective brackets 11 of the drive device 2.
  • the outlet nozzle 22 is relatively short and angled in such a way that it continues the lower end of the channel-like wall 19 in a straight line, it having a semicircular disc-shaped cross section.
  • the funnel storage housing 24 has a lower opening 26, which is semicircular in shape and lies in the lower region of the rear wall 24.
  • the free end of the outlet nozzle 22 is chamfered and forms an outlet opening which is surrounded by a counter flange 27 which is semicircular and rests on the flange 17.
  • a semi-circular locking slide 28 is attached to the wall 24 by means of a pivot bearing 29. In the closed position shown in FIG.
  • the closure slide 28 covers the lower opening 26 and lies against the lower region of the front wall 19 which is curved in the manner of a channel.
  • the slide valve 28 Via the pivot bearing 29, the slide valve 28 is connected to an outside of the hopper storage housing 18, close to its rear wall 24
  • Hand lever 30 connected to be pivoted into an open position and back.
  • the feed device 5 is fixed to the mixing housing 3, specifically at its cylindrical region, by means of a coupling device, to which two hooks 31 belong, which are fastened to the rear wall 24 of the funnel storage housing 18.
  • the two hooks 31 are spaced from one another and are hung from above via one of the two pins 15.
  • the flange 17 and the counter flange 27 are connected to one another at the front by a screw connection 32, which likewise belongs to the easily detachable coupling device.
  • the stand frame 6 has a cross piece 33 at the top, which extends at right angles to the plane of the drawing in FIG. 1 and carries a pair of rigidly attached legs 34, each of which is provided with a wheel 35 and only one of which is shown. Another pair of legs 36 is provided, only one of which is shown in the drawing and which are attached to the top of the crosspiece 33 with a swivel 37. These legs 36 are fixed to the crosspiece 33 by means of a clamping screw 38 and can be pivoted after loosening the clamping screw.
  • the crosspiece 33 has a semicircular recess which is delimited along the bottom by a support plate 39.
  • the mixing housing 13 is inserted into this recess in such a way that the radially projecting U-brackets 14 protrude from above the cross piece 33 and its support plate 39.
