  • the receiving disks are equipped with abrasive carriers or with diamond-occupied discs.
  • a disadvantage of the previously known device is that the milling rollers subject to a strong closure can only be exchanged with great difficulty and with the use of tools.
  • the milling rollers have only a short service life, which is particularly due to the fact that the resulting in the course of tillage particulate matter penetrates into the camp, causing them to be affected.
  • This fine dust leads to an impairment of the run-out behavior, whereby the rolling axes often bend the inner screws, whereby their disassembly is difficult.
  • the invention aims to remedy this situation.
  • the invention has for its object to provide a device for surface treatment of soils for mounting on a driven pickup disc of a floor grinder, the milling roller is easy and tool-free interchangeable and avoided in the ingress of particulate matter in the storage. According to the invention, this object is solved by the features of the characterizing part of patent claim 1.
  • a device for surface treatment of floors and coverings for mounting on a driven pickup disc of a floor grinding machine is created, the milling roller is easy and tool-free interchangeable and is avoided in the deterioration of storage by fine dust.

  • the radial bore at least partially a smaller one Diameter than the ball, through which a complete passage of the ball is prevented from the radial bore.
  • a corresponding effect can be achieved by providing radially expansible pins on the shaft instead of the balls.
  • the disengagement pin has at least one reduced-diameter portion into which the fewest one ball can be moved radially at least in regions.
  • a release of at least one ball is made possible by axial movement of the disengaging pin, whereby a simple stripping of the milling roller is made possible by the shaft.
  • the region for the axial fixation located in the recess disposed within the milling roller at least one ball can in this case recede into the reduced diameter portion of the release pin.
  • the release pin is resiliently mounted in the axial blind bore, from which he protrudes end.
  • the release pin is biased in an end position in which the at least one ball is pressed by the radial bore of the shaft to the outside.
  • To release the axial fixation of the Ausgurll against the spring can be moved axially such that the at least one ball can retreat into the reduced diameter portion of the disengaging pin, after which the milling roller can be easily removed from the shaft.
  • the recess arranged in the milling roller for engagement of the at least one locking element is formed by a circumferential groove. This allows a radially arbitrary positioning of the locking elements, whereby the mounting of the milling roller is facilitated on the shaft.
  • the means for tool-releasable attachment of a milling roller comprise at least one, preferably a plurality of drivers, which engage in a corresponding recess of the milling roller.
  • at least one catch receptacle can be arranged, in which engages a corresponding, arranged on the milling roller driver.
  • the driver is formed by a non-circular, preferably polygonal outline of an end region of the shaft, which engages in a corresponding with this shaft receiving the Fräsrolle.
  • the shaft may have an enlarged diameter relative to the free end of the shaft portion through which a shoulder is formed, are arranged on the at least two, preferably three axially cantilevered, preferably cylindrical driver, in which corresponding recesses of the milling roller intervention.
  • an encircling web is advantageously formed on the front of the milling roller, which surrounds the enlarged diameter portion of the shaft. This counteracts the penetration of fine dust into the positive connection between the milling roller and the shaft.
  • the housing is formed dust-tight enclosing the storage area of the shaft. As a result, an impairment of the running properties of the shaft bearing is prevented.
  • the present invention is further based on the object to provide a milling roller for use in a device of the aforementioned type, which allows a simple, tool-free replacement. According to the invention, this object is achieved by the characterizing part of patent claim 14.
  • a milling roller for use in a device of the aforementioned type is provided, which is easy and tool-free interchangeable.
  • the shaft receptacle is formed by a blind bore.
  • a one-sided closed tool holder is achieved, whereby the entry of fine dust during tillage is counteracted.
  • the shaft receptacle has a non-round cross-section, preferably in the form of a polygon.
  • a positive connection of the milling roller with a correspondingly corresponding shaft can be achieved, whereby a radial fixation is effected.
  • at least one, preferably three holes for receiving arranged on a male shaft drivers may be mounted in the milling roller on its front side adjacent to the shaft receiving at least one, whereby a corresponding positive engagement can be achieved.
  • Anstell the at least one, preferably three holes can be arranged here or preferably three preferably cylindrical trained driving pins here.
  • the end of the shaft receiving an axially projecting circumferential web is integrally formed.
  • FIG. 1 is an exploded view of a device for surface treatment of trays for mounting on a driven take-up disk of a floor grinding machine;

  • Figure 4 shows the representation of the housing cover of the housing of Figure 3 a) in front view
  • FIG. 6 shows the illustration of a receiving disk for a floor grinding machine with a device mounted thereon according to FIG. 1
  • the chosen as an embodiment device for surface treatment of soils for mounting on a driven pickup disc of a floor grinder consists essentially of a housing 1 in which a shaft 2 is rotatably mounted, which is provided with a milling roller 3.
  • the housing 1 is substantially cuboid-shaped, wherein its upper-side cover surface is beveled saddle-roof-shaped.
  • a bore 1 1 is introduced, in which about two thirds of its length, a circumferential ridge 12 is formed, wherein the bore 1 1 is formed enlarged in diameter after the web 12.
  • This diameter enlarged range 1 1 1 serves to receive sealing rings 6 for dust-tight sealing of the housing first
  • two deep-groove ball bearings 4 arranged one behind the other are introduced into the bore 11 for rotational mounting of the shaft 2.
  • the housing 1 is closed by a cover 13 which is provided with a bore 14 corresponding to the bore 1 1 of the housing 1.
  • the bore 14 delimiting the lid 13 is an annular shoulder 15th formed on the inside of the enlarged diameter portion 1 1 1 of the bore 1 1 is applied.

  • the shaft 2 has a threaded portion 27 provided with an external thread. In the axial bore 20 of the shaft 2, a release pin 28 is introduced.
  • the Ausschky 28 is biased in the axial bore 20 via a - not shown - arranged within the axial bore 20 spring, such that a movement of the Ausschreibxs 28 takes place in the direction of the holes 21 against the spring tension. Furthermore, in the disengaging pin, a groove (not shown) is provided, which is circumferentially provided around the circumference of the diameter of the ball 22. In this case, this - not shown - groove is positioned so that when pressed-Ausgurjanjan 28, the balls 22 can recede into this - not shown - groove.
  • the thus formed shaft 2 is inserted into the bore 1 1 of the housing 1, wherein the enlarged diameter portion 23 abuts on the circumferential rib 12 via the sealing rings 6.
  • the shaft 2 is rotatably mounted in the deep groove ball bearings 4 penetrated by the latter and has two rotors mounted on the same.
