Kunststoffwerk Philippine GmbH k Co. KO, 5420 Lahnstein 2 Device «for producing and transporting concrete

The innovation relates to a device doing manufacture and transporting concrete, with a rotatably mounted on a chassis and equipped with a drive Mixing drum, which is supported on the chassis in the area of its open end to accommodate an inlet funnel, an outlet funnel and a mostly swiveling chute is assigned.

In such known devices, the inlet funnel, the outlet funnel and the chute are made of sheet steel manufactured and are subject to a high when adding the aggregates or when emptying the mixing drum Wear, so that they have to be replaced relatively often. The replacement of these parts is, partially due to the high weight of the same, associated with a not inconsiderable expenditure of time. During this The device cannot be used for a period of time. In order to increase the service life of these parts, it is known that the to provide heavily used surfaces of the same with special reinforcement or wear plates. This increases However, the weight of these parts and the increase in stability achieved is only relatively small. Such a device in which the inlet funnel, outlet funnel and chute are made of sheet steel, however the fundamental disadvantage that the filling of the aggregates and the emptying of the mixing drum with are associated with a high level of noise. In addition, care must be taken that both the discharge funnel as the chute must also always be carefully cleaned, there

Further features and advantages of the innovation are described below using an exemplary embodiment shown in a drawing explained in more detail. Thereby «own

Fig. 1 shows a back view of a? Device according to the invention and

2 shows a section through an only partially drawn wall of the discharge funnel of the device.

In Fig. 1 of the drawing is a known per se Transport concrete mixer 1 shown in a simplified manner, which has a chassis 2 on which a mixing drum 3 with is rotatably mounted on a drive, not shown. Below the open end of the mixing drum 3, so in rear part of the chassis 2, braced on the same a support frame 4, on which an inlet funnel 5, a discharge funnel 6 and a chute 7, which are directly located under the discharge funnel 6, fastened interchangeably are. The chute 7 is pivotably held on the supporting structure 4 and, if necessary, can be parts not drawn can be extended.

The discharge funnel 6 consists in this exemplary embodiment from a relatively thin, made of a perforated plate reinforcement 8, which on both sides with a Layer 9,10 made of highly wear-resistant plastic, for example polyurethane elastomer, is provided. The plastic material of the two layers 9,10 also extends through the openings 11 of the reinforcement 8, so that the two Layers 9, IO are firmly connected to one another.

In the illustrated embodiment, the funnel-shaped one is first Reinforcement 8 made in one piece, which is then overmolded with plastic in a suitable form. It is it is also possible to make the discharge funnel 6 from two parts, which are screwed together, for example. The individual parts of this discharge funnel 6 can be in be manufactured in such a way that the then two-part reinforcement 8 is cut from corresponding, flat perforated metal sheets is, which only after it has been encased with plastic, for example with additional heating, into the discharge funnel 6 can be bent to the appropriate shape.

The fastening parts, which are not shown in the drawing for the sake of simplicity, with those in the case of a two-part Outlet funnel 6 the parts of the same are connected to one another, and the, in a different design, for connecting the Discharge funnel 6 are used on the supporting frame 4, are firmly connected to the reinforcement 8 and protrude through the plastic layer 9 or 10.

The inlet funnel 5 and the chute 7 including their extension parts are in the same way as that described Discharge funnel 6 formed. It is possible to use the Reinforcement 8 can also be made of expanded metal, wire or chain mesh, glass fiber reinforced plastic or molded material. Polypropylene, Polyethylene or polyamide can be used.
