DE4122974A1 - Metering disintegrator for foam scrap - has container with endless driven chains which move angle bars across base so as to scrape underside of foam and take particles to outlet - Google Patents

Abstract

Appts. for disintegrating and metering out plastic foam pieces (also mixing with other material if required), and partic. scrap material, has a box-like container with open top above a drive system with two endless chains running along the length; a number of angle pieces are attached to these at set intervals so as to run over a base of the container; these scrape the pieces of foam in the container and convey them to the outlet at the end. ADVANTAGE - The appts. is simple, readily transported, and suitable for use at site.

Description

The invention relates to a device for crushing, Dosie ren and if necessary admixing pieces of plastic foam, especially of pieces of waste.

In horticultural companies, landfills and sports facilities, at for example on riding arenas, it is often desirable to be small ne plastic foam particles of the processed earth Mix loosening of the soil.

The present invention is based on the object a device for crushing, dosing and, if necessary, mixing of plastic foam pieces, in particular waste pieces, to create that simple in structure, easy to transport and use on the spot.

To solve the task, a device is suggested type, which thereby is marked that in the lower area one above  open, used to hold the foam pieces, box-like container a drive device for two endlessly rotating in the longitudinal direction of the container Chains are provided on which several, via a Bo the toothed angular rails running in the container certain distances are attached to the concentric run Particles from the foam used in the container scrape pieces and put one at the end of the container orderly discharge.

The drive device for the chains can, for example from one on a freely rotatable axis in one End region of the container arranged gear pair and one on one driven by an electric motor Be axis in the opposite end of the container consolidated drive gear pair exist, being in the area over the axis of the non-driven gear pair a stop wall is provided for the foam pieces is.

Finally, at the top of the container in the loading rich a narrow, upper longitudinal edge of the container a steel lid for weighting the foam pieces be pivotally mounted.

With the device according to the invention the essential Advantage achieved that more or less large foam pieces of fabric, such as those found in packaging or the like. incurred as waste, inserted into the container can be, causing the bottom of this foam pieces of fabric particles through the toothed elbows be scraped off during circulation. The drive Direction for the chains can be done by a stepless right electric motor can be operated.

Based on the drawings, one example should be preferred  th embodiment of the device according to the invention are explained.

In the drawings shows

Fig. 1 shows a schematic side view with a partial elevation view of the device according to the invention,

FIG. 2 shows a top view of the device according to FIG. 1,

Fig. 3 shows a partial cross section with a view in the direction of the narrow side of the device.

As can be seen from the figures of the drawings, the device of the invention essentially consists of a rectangular, box-like container 1 , which has a bottom 2 in the lower region.

In the lower region of the container 1 , a Antriebsein direction for two chains 3 , 4 running endlessly in the longitudinal direction of the container is provided. This Antriebsein direction consists of a pair of gear wheels 6 , 7 arranged on a freely rotatable shaft 5 in an end region of the container 1 and a drive gear pair 10 , 11 fastened on an axis 9 driven by an electric motor 8 in the opposite end region of the container.

On the lying on the corresponding gears and endlessly revolving chains 3 , 4 in certain stands from several, on the top over the bottom 2 in the container 1 running, toothed angle rails 12 are attached at certain intervals.

As is apparent in particular from FIG. 1, in order scraped run of the toothed angle bars 12 in the direction of arrow 13 material pads of the inserted into the container foam 14 on the underside of particles and supplied to a arranged at the end of the container ejection 15th So that the foam blocks find a stop, a baffle 16 is arranged in the front region of the container 1 .

In order to weigh down the pieces of foam in the container, a steel cover 17 can be pivoted in the area of a narrow, upper longitudinal edge of the container.

The operation of the electric motor can be carried out by a suitable time switch 18 .
