Material compacting device on concrete block making machines

The innovation relates to a material compacting device of concrete block making machines that have a Support plate for concrete block molds, a vibration device and a loading device which can be lowered onto the concrete block molds.

In a known device of this type, unbalance vibrators are arranged in a carrier, which is supported on a foundation with the interposition of bellows cylinders. The bellows cylinders should be once take over the task of usual vibrating elements and also be used as lifting elements.

However, this known arrangement has the disadvantage that the vibration behavior of the material compacting device depends to a considerable extent on the respective size of the stroke of the bellows cylinder. Accordingly, when using this known device, a perfect compression of the mass can only be achieved with a certain stroke of the bellows cylinder. This known device has therefore not found its way into practice.

The innovation is therefore based on the object of a material compression device of the type mentioned at the beginning Art to create in which the vibration behavior at any height setting of the table or The carrier remains constant and thus the desired degree of compaction of the mass can always be precisely achieved is.

The solution to this problem is essentially that the or each table of the innovation Vibration device with the interposition of spring elements on one bearing the vibration elements The substructure is arranged and the substructure is continuously height-adjustable by means of a mechanical lifting drive is.

Another advantageous embodiment is thereby characterized in that the or each table of the vibration device with the interposition of Federeleraenten is supported on a stationary substructure carrying the vibration elements and which forms the concrete block load-bearing plate is adjustable in height.

While the concrete is being poured into the molds it is advantageous to work with a lower vibration force than during the main compression process, i.e. after lowering the load on the formon content. This possibility is through different Given that the vibration device is started up.

Since, as already mentioned, the Unwuchlmotoren can run continuously throughout the operation time now, in addition, the possibility is given, the speed of the Unwuclitmotoren that consistently was constant at 3000 rpm before, by a commercially available converters in wide Gi •• u .-.

and in this way to achieve optimal compaction of the concrete for every stone shape.

In the drawing, the innovation is illustrated in an exemplary embodiment.

Fig. 1 shows the side view of a compression device designed according to the innovation,

FIG. 2 is a plan view of the lower part of the device according to FIG. 1.

In the illustrated embodiment, the are for production of concrete blocks serving forms 1 arranged on a wooden plate 2, which are fixedly arranged on webs 3 of a Frame rests. Laterally next to the plate 2 are upright cylinders 4 arranged in a stationary manner Pistons 5 are arranged, which are connected to clamps 6. Between these clamps 6 and the mold frame 7 are j Helical compression springs 8 arranged. This arrangement allows the molds 7 to be firmly clamped on the plate 2.

Above the plate 2 with the molds 1 is a known loading device 9 by means of a piston-cylinder unit arranged so that it can be raised and lowered.

Below the plate 2, a vibration device is provided, which in the illustrated embodiment consists of a Substructure 11, two arranged on this substructure with the interposition of spring elements 12. Tables 13 and under Tables mounted unbalance motors 14 consists. The vibration device designed in this way is by means of a lifting drive infinitely adjustable in height. In the illustrated embodiment, this lifting drive consists of two eccentric shafts 15, which are coupled to a motor 18 via pairs of bevel gears 16 and intermediate rolls 17.

But it is also possible to provide another suitable lifting drive for the vibration device.

It is also possible for the vibration device to be stationary and for the plate 2 carrying the molds 1 to be in height adjustable so that they are out of contact with the vibration device after each compression process can be brought.
