Abstract

The stone-cleaning machine cleans all common paving stones in situ (even clinkers), where they have been taken up and are to be laid again. With the cleaned stones, laying as they were laid before is made possible again. By the adjusting possibilities of the guiding frame and the nozzles, all types of stones can be optimally cleaned, with the minimum expenditure of air.

Description

The invention relates to a mobile stone cleaning machine for Clean old or dirty paving stones of all shapes with a grate.

EP 00 47 041 A2 is a mobile stone cleaning machine known from a wheel bearing with a rotary drum shovel in the form of a cage-like grate. With the rotary drum The dirty paving stones are picked up and shovel then the filled rotating drum blade in the form of a rotated cage-like grate. By turning the drum Sand and gravel were thrown out. When tumbling the Paving stones can easily be damaged; also is the use of this stone cleaning machine in the form of a wheel bearing the rotary drum shovel can only be cleaned for large quantities Paving stones economically.

Based on this prior art, the invention lies Based on the task of creating a mobile stone cleaning machine, with the gentle cleaning of paving stones is and which can also be used cost-effectively for smaller quantities is.

This object is achieved in that the Grate A flat iron grate is attached at right angles to the direction of travel welded pipes and a lead frame with a device to accommodate the tubes, the tubes being received by two Sides and crossways to the direction of travel over the pipes of the flat iron rust is pushed and compressed air nozzles over the flat iron grate are arranged to blow off the paving stones with excess pressure.  

The stones slide more easily due to the slanted grate the machine. It therefore contains the pushing into the machine.

The compressed air nozzles are movably attached to the guide frame and can be adjusted in width depending on the type of stone to be able to work at different widths and in height, if the stones have different strengths.

Depending on the degree of contamination, larger or smaller nozzles can be used be set.

The larger nozzles have the disadvantage that more compressed air is required is, which must be produced expensive with a compressor.

In the embodiment according to claim 4, the stone cleaning machine has a protective box ( 6 ) which insulates the noise and prevents the dirt from splashing away. The dirt will only blow down. For this reason, the two rubber flaps are also necessary.

According to claim 5, a scraper on the stone cleaning machine intended.

Since the stones are not blown off from below, scraping off is necessary necessary. The wiper must be arranged at an angle to prevent jamming to prevent the stones.

The guide frame is to make the stones easier to insert 10 cm apart at the upper end.

In the drawing, the invention is based on an exemplary embodiment game explained in more detail. It shows  

Fig. 1 shows the side view of the stone cleaning machine and

Fig. 2 is an exploded view of the stone cleaning machine.

All paving stones can be cleaned with the stone cleaning machine. For this purpose, the paving stones are pushed over the grate ( 8 ) and blown off from above and from the side with the compressed air nozzles ( 3 ) arranged here in the example, 2 pieces per side.

The compressed air must be 6-7 bar and is generated by a compressor. At the connection ( 1 ) there is a valve ( 2 ) for switching on the compressed air directly on the stone cleaning machine, since this saves fuel on the compressor.

Since the job is progressing feet ( 10 ) and the wheels ( 11 ) are attached to the stone cleaning machine. This makes it easier to move the stone cleaning machine. Since the machine works with compressed air, only the compressed air hose has to be tightened.

Since there are different stone sizes and types z. B. 10/20/8, T-Pro fil, it is necessary that the guide frame ( 7 ) is adjustable over the grate. Loosening and locking is done with the locking screw ( 9 ). At the same time, the nozzles ( 3 ) are also moved, since they are screwed onto the guide frame ( 7 ).
