Definitions

Mobile surface treatment devices such as those used in particular for cleaning concrete floors or removing road markings, work with rotor cages on whose horizontal cage bars a large number of processing elements are arranged.
the rotor cages are motor-driven and the device can be moved over the floor.
Small surface processing machines usually only have one rotor drum. Despite the large number of machining lamellae, the machined surface shows a clear groove pattern. The device is moved by the reaction force of the lamellae, which hit the floor tangentially.
This device which represents the essential prior art here, works with a centrally driven rotor shaft, on each of which a rotor cage is arranged.
the main advantage of this relatively small device is the excellent use inside buildings, because of the easy mobility and the optimally used processing width.
the disadvantage of the latter device is the remaining unprocessed strip between the two rotor cages and the groove pattern caused by the processing lamellae in the processed area. While the device does not leave any untreated stripes according to EP-A-0 098 798, the groove pattern remains. In the case of cleaned concrete floors or ship ceilings in particular, the groove pattern must be removed by additional processing steps such as sanding or filling. In addition, even with smaller processing devices, a feed reaction movement is no longer desired for safety reasons. Despite warnings from the manufacturers, the user personnel let the devices continue to run uncontrollably while they are doing other work for a short time.
the mobile surface processing device essentially consists of a self-supporting protective housing, which serves as a chassis and is generally designated by the reference number 1, and a motor M arranged thereon, which drives the rotor shafts 5 arranged within the protective housing 1 via a vertical output shaft 11.
the Rotor shafts 5 are mounted and driven centrally and protrude from a gear housing 15 on both sides.
Each rotor shaft 5 is positively and / or non-positively connected to the rotor cages 4.
Each rotor cage 4 comprises two side cheeks 40, between which cage bars 41 run, on which freely rotating abrasive impact processing blades 42 are lined up. The rotor cages 4 are held securely on the rotor shaft 5 by means of a releasable fuse 43.
the wheel axles 8 are fastened to the chassis or protective housing 1 via pivotable arms 7.
the wheels 6 are mounted freely on the wheel axles 8.
the swivel arms 7 are used for the relative height adjustment of the protective housing 1 with respect to the surface to be machined.
the pivotable arms 7 are operatively connected to a connecting rod 10 via a handlebar, which causes the two wheel axles 8 to pivot parallel.
the height adjustment is carried out by an operator who actuates an actuating rod 9, acts on one of the two wheel axles 8 and thus also on the second wheel axle via the parallel guide by means of the connecting rod 10. Thanks to this solution, it is consequently unnecessary for the rotor shafts 5 or the rotor cages 4 arranged thereon to be height-adjustable with respect to the protective housing 1.
the drive motor M which is indirectly attached to the protective housing or chassis 1, on the one hand drives the rotor shafts 5 and, in addition, sets the gear housing 15, in which the rotor shafts 5 are mounted, into a rotational movement a vertical axis.
the rotor shafts 5 are driven directly by the vertical output shaft of the motor M, which is extended directly into the gear housing 15.
the deflection is only 90 ° by means of a known bevel gear.
the rotor cages also called milling drums or lamellar drums, are usually used at speeds of 1500 to 1700 rpm. operated. It is advantageous if the rotor shafts 5 are driven in opposite directions. Thus, one drum works in rotation and the other drum runs in opposite direction to the horizontal rotation. This results in a higher work output and a better quality of the milling pattern without so-called shadow formation.
the gear housing 15, in which the rotor shafts 5 are mounted cannot and must not rotate at the same speed.
Usual rotation speeds for the gear housing 15 are 50 to 150 rpm.
a transmission belt, for example a flat or toothed belt, runs over this output pulley.
This strap is on the other hand over a pulley 22, which is rotatably mounted on a transmission shaft 23.
the transmission shaft 23 is guided in a corresponding bearing and passes through the protective housing 1.
the shaft bearing which is not further described here, is of course firmly arranged on the protective housing or chassis 1.
a chain or a toothed belt runs over this small chain or toothed wheel, which transmits the torque of the abovementioned drive wheel 19 to a drive wheel 18.
the drive wheel 18 is in turn also a chain or toothed wheel, which is of correspondingly large dimensions in order to achieve the desired reduction.
the gear housing 15 is set into the desired rotational movement via this drive wheel 18.
the transmission housing 15 is thus driven in two stages via two transmissions, a first transmission 21 being arranged above the protective housing 1 and a second transmission below the protective housing 1.
the connection between these two transmissions is the transmission shaft 23 described, which penetrates the protective housing 1.
the motor M is arranged above the protective housing 1 via a sleeve-like bearing housing 13.
the vertical output shaft 11 of the motor M is supported in a concentric hollow axis which has the shape of a sleeve 16 with a collar. Between the collar of the sleeve 16 and the flange-shaped widening of the gear housing 15, the drive wheel 18 described earlier is held in a non-positive and / or positive manner.
the concentric hollow axis is mounted in the bearing housing 13 by means of roller bearings 14 which can be loaded radially and axially.
roller bearings 14 which can be loaded radially and axially.
the transmission running below the protective housing 1 is thus in the area of high dust generation.
a cover 20 is provided which is screwed onto the protective housing 1 from below and is accordingly protected against vibrations. This cover 20 is thus stationary and is sealed against the rotating flange of the gear housing 15 with a sliding seal 25.
the advantages of the device according to the invention over known tillage implements of the type mentioned at the outset are considerable.
the surface is processed much more evenly due to the superimposed rotary movements.
the direction of impact on the surface varies constantly. Grooves no longer occur. Pores or unevenness in the surface to be machined are better removed by machining on all sides.
a particularly important side effect is that the rotating rotor cages do not generate any self-propelling force on the device during processing. This means that the device will no longer move automatically if the operator briefly releases the device. This significantly reduces the risk of accidents at work.
a further cover which at least protects the transmission 21, will surely be fitted over the chassis or the self-supporting protective housing 1.
the basic idea of the invention is to be seen in the fact that the rotor cages 4 are set in two different rotary movements, namely on the one hand around the horizontal axis in which the rotor shafts run, as was previously customary, and secondly by the superimposed rotary movement about a vertical one Axis in which the output shaft of the motor runs.
the horizontal rotation of the two rotor cages it is important that one rotor cage is milling and the other drum is working in opposite directions. This demonstrably increases the work performance and ensures that no so-called shadow formation occurs. The visual appearance is therefore free from milling marks, which reveals a rotary or other preferred movement.
