Dosing device, in particular for exposed aggregate concrete

The present renewal relates to a metering device,

cpe for · V & 5Chb6töDVüi * 3ätZ.

With such metering devices there is a requirement that a mostly funnel-shaped container always has a specific one To remove the amount of exposed aggregate concrete and then to put it in a form provided for it. It is known to accomplish this If necessary, a pipe with a shut-off valve under the tank

/ schiebenaanzuringen, which alternately open the pipe and close, where there? Increase or decrease the amount

V takes place by adding or removing rings, whereby the distance between the gate valves is larger or smaller.

However, these metering devices have the disadvantage that the conversion to another set is associated with a large amount of assembly work. In addition, the known metering devices very expensive and it is not possible to set the desired amount.

The innovation is therefore based on the task of a metering device to create that, through simple structural measures, enables fast and precise dosing while at the same time significant cost reduction.

After the hiring, the object is achieved in that there is at least one safety valve under a funnel-shaped container aua fiaaciiaiam material garavtigea * mein, anon toaraa-eig « is and transversely to the longitudinal axis of the hose swei pairs of clamping jaws are arranged at a distance from one another, the distance the pairs of clamping jaws are mutually variable.

The goal parts achieved with the veneer are in particular in that the exact dosage of the desired amount of faced concrete attachment can be carried out quickly and easily and the costs for manufacturing the metering device are very low.

C Another idea of the fire is that the terminal block pairs a clamping plane can be actuated by only one pressure cylinder, since? as the atimaaita eisaa is sighting of the LÜSgaaehae da «ZyündaM bawagllehap latasena attached and its Piston is connected to a guide rail, which is on guide rods is arranged displaceably and provided with at least one clamping jaw, which at least one clamping jaw against is assigned overlying, wherein this jaw is arranged on the other end face of the frame.

- Hit this arrangement, the portion of the gate is obtained that for each C clamping level only a pressure cylinder is necessary, It does not matter whether only one or more pairs of clamping jaws have to be actuated within a clamping plane.

Another idea of the fire is that the clamping jaws articulated and are rounded on the side facing the hose.

This ensures that the clamping jaws do not damage the viewing tube when it is closed.

Another idea behind the reinforcement is that stop pieces are attached to the guide rods in such a way that the The clamping jaws can only be moved up to approximately the middle of the eye.

Far more, a thought of hiring consists in the fact that the distance the spacers to each other by continuously adjustable spacers is variable.

This makes it easy to create a! differently large dosing quantities take place and likewise is one Adjustment of the required amount is possible.

In the further embodiment of the improvement, the clamping jaws pivotally mounted on a horizontal also horizon- tal ~ * pivotable pendulum beam are arranged in the arrangement of two pairs of clamping jaws in a clamping plane.

This pivotability ensures that the jaws can be set parallel to each other in each case and the Hose perfect s & klsases.

An embodiment is shown in d &. Drawings shown and is described in more detail below

Show it:

Figure 1 is a vertical section through a new Doeiervor-O direction,

Q Figure 2 shows a horizontal section through the metering device.

The dosing device shown has a funnel-shaped container 1 in which the good to be dosed, e.g. Vaschbetenvorsats, is located

The container 1 is equipped with two filling openings, each of which has a hose made of flexible material 2 is attached. Aa the bottom underside of the funnel 1, two plates 3 are attached, which by Fumresgsetangen 4 on the lower End connected. Between the two plates are a guide rail 5 and a on the guide rod & 4 Side 6 of a rigid rectangular frame 6,?, 8 displaceable arranged «on the leg 8 of this web 6, 7» 8 is

• fastened in the pressure cylinder 9, the piston 10 over an intermediate piece 11 is connected to the guide bar 5.

Fork 12 attached, in which a pendulum beam 13 is pivotable is attached. In the outer ends of the pendulum balls 13, the clamping jaws 14 are also via a further fork 15 horizontally pivotable and articulated on an axis 16. Stop pieces 17 are attached to the guide rods 4, which prevent displacement of the clamping jaws 14 beyond the center of the hose. The plates 3 are stepless adjustable spacers 18 attached to which via) a bracket 19 another clamping device is attached.

If the pressure cylinder 9 is actuated, it initially shifts the guide bar 5 and thus also the clamping jaws 14 on the Schiauehaitte until the guide bar 5 as the stopper 17 is present. Then the frame 6 moves, 7, 8 in such a way that this leg 6 is moved towards the center of the hose and ext, via the clamping jaws 14, pressing the Hose 2 takes place.

\ Due to the rounding 20 of the jaws 14, damage to the tube 2 is prevented on compression.
