    专利说明:

    The present invention relates to a spring element to a tillage machine according to the preamble of patent claim 1.
    Especially for the renovation and repair of floor coverings various processing machines are used.
    On the one hand known for the rough machining of asphalt, concrete or other hard surfaces milling machines. A machine of this type is described in EP 0 661 144 B1. Such machines are equipped with tools as disclosed in US Patent Publication No. US 2003/0062 760 A1.
    The rough elimination of ground unevenness can be achieved with milling machines mounted on the milling wheels are achieved with high efficiency. This treatment is excellently suited for the preparation of surfaces on which another coating is applied. However, if the result of a finely ground surface is desired, another tool must be used.
    If you want to remove dirt on a flat plate floor and / or very small bumps are eliminated, you take for fine processes floor grinding machines, with the appropriate grinding tools. Such a device is e.g. presented in WO 2006/000 542 A1.
    The use of abrasive together with abrasive contents provided liquids, is very good for dirt removal and fine sanding. With this treatment, a uniformly fine surface can be achieved. However, when rough bumps have to be removed, the known tools for floor grinding machines are not suitable because they do not sufficiently accommodate the bumps.
    Both devices are well used for the intended area and are eingesezt in practice in a variety. But when it comes to a universal tool to be used to remove on many different coverings dirt and unevenness should be compensated, the tools mentioned are too special. In applications ranging from rough machining of surfaces to the finest removal of dirt and sanding of surfaces, there are no suitable tools. In particular, for the machining of wood surfaces missing the appropriate tools.
    Grinding machines, such as e.g. described in CH 699 037 B1, avoid the grinding in of traces in fine surfaces by fixing the grinding tools on an elastic covering (foam, rubber, etc.). They adapt well to a smooth and fine surface like that of a flat plate floor. However, the flexible attachment of the grinding elements makes it impossible to intensive processing of the plate floor. Too much pressure on the tools, which is necessary to compensate for unevenness elastically reacting, the frictional resistance increases on the plate floor. This has the consequence that the individual tools tend in the elastic covering and leave unwanted traces in the bottom of the plate. Completely unfit are such grinders and their tools for working on wooden floors.
    The present invention now has the task of designing a tool for a tillage machine of the type mentioned in such a way that many tasks that previously either with great effort by means of two tools, or could not be performed, with one and the same tool can be concerned.
    This object is achieved by a spring element to a tillage machine with the features of claim 1. Further inventive features will become apparent from the dependent claims and the advantages thereof are explained in the following description.
    In the drawing shows:

    The figures represent possible embodiments, which will be explained in the following description.
    In Fig. 1, a spring element 1 is shown, which is mounted on a base of the tillage machine. The base may be both a disk 10 (Figures 3 and 4) or a drum 20 (Figures 5 and 6), each driven by a motor. The processing of the floor covering 30 takes place by parallel lowering of the base, so that a plurality of such spring elements 1 with the abrasive coating 2 on the floor covering comes through the weight of the same (Fig. 7 -Fig. 9).
    The lowering of the machine, so the approach of the base to the flooring, either manually, or by means of a mechanical device. Depending on the degree of depression B, (FIG. 7, FIG. 8 and FIG. 9), the intensity of the processing can be influenced. With gentle lowering B fine machining of the floor covering 30 takes place with little load on the spring element 1 and small deflection (FIG. 8). At full load and large deflection B of the spring element 1, the processing of the floor covering 30 is more intense (FIG. 9). Depending on the partial load (FIG. 8), the processing of the floor covering 30 takes place more or less intensively. The total deflection of the spring element 1 will be achieved either by its own weight, or an additional weight on the tillage machine. In extreme cases, until the resilient part 6 rests on the base (FIG. 9).
    With a rigid tool varying the load of the tool in a larger area can not be achieved. If the load is too great, a rigid tool usually causes clear traces in the floor covering 30. This can also be done with full spring deflection of the spring element 1 (FIG. 9). Therefore, according to the invention, the abrasive coating 2 (FIG. 1) is applied to the flexible spring element 1 in such a way that the abrasive coating 2 processes the floor covering 30 over the whole area of the deflection with different force (FIGS. 7, 8 and 1). 9).
    In order to achieve an additional degree of flexibility in the force to act on the flooring, so the abrasive coating 2 is applied directly to the resilient member 6, the spring element 1 or attached thereto. This achieves the desired flexibility of the force exerted on the abrasive pad 2. The effect on the floor covering 30 can be varied so much finer. Various spring elements 1 can be provided with different grain size of the abrasive coating 2, depending on the application. The material of the abrasive coating 2 may in principle be any abrasive material, common are, among other materials emery, hard metal and diamond chips. But it can also consist of a rasp or a planing tool, which is mounted on the spring element 1.
    By choosing the thickness d of the spring element 1, the deflection of the spring 4 of the spring element 1 can be adapted for the effect on the floor covering to be treated and the weight of the machine. At a load of 4-10 kg, the resilient part 6 should usually compress about 2-6 mm. This is achieved only by selecting the right material for the production of the spring element 1. It is quite conceivable that the holder 5 has a different thickness d, as the spring 4 and the spring 4 in turn may have different thicknesses d over the extent thereof.
    Several such spring elements 1 are releasably secured to a base so that they can be easily replaced if necessary, against new, unused spring elements 1. The base may be a horizontally rotating disc 10, wherein at least one spring element 1 is mounted within the outside diameter 11 (FIGS. 3 and 4). The deflection of the spring elements prevents too great differences in the processing intensity, if the disc 10 would not really performed parallel to the floor covering 30. The disc 10 rotates at low speeds, from 150-1000 rpm.
    Another possibility is the assembly of spring elements 1 on the surface 21 of a drum 20 (Figures 5 and 6). In addition to the spring effect, when used with a drum with the varying speed an additional effect can be achieved. Depending on the rotational speed of the drum 20, the centrifugal force is different. The higher the speed, the stronger the centrifugal force acts on the deflection of the spring element 1. As a rule applies in this application: the higher the speed, the stronger the force that is necessary to achieve the deflection of the spring element 1. At low speed, especially the spring constant of the spring 4 acts.
    If the base is a disc 10, it rotates about a vertically arranged drive shaft, parallel to the floor covering. With the spring elements 1 mounted thereon (FIG. 4), such a disk 10 has passages 12 through which the dust caused by the abrasion can be sucked off. With the recess 13, the disc is fixed to the shaft of the motor.
    While the disc 10 rotates horizontally, a drum 20 used as a base moves parallel to the floor covering 30 about a horizontally arranged axis, via which the central support and guide 21 of the drum 20 takes place.
