Definitions

  • the present invention relates to a mobile material-removing Soil cultivation device according to the preamble of patent claim 1.
  • Soil cultivation devices have been used by the applicant for decades manufactured and distributed. It is about this always around devices where one or two rotor drums are rotating Movement.
  • the rotor drums are as Cages designed, on the cage bars a variety of processing elements are lined up. These editing elements have a through hole, the diameter of which is quite a bit is larger than the diameter of the cage bars.
  • Through the rotation the machining elements of the rotor cage hurled outside and hit the one to be worked like a hammer Floor area.
  • Such devices have appeared in many Applications proven for years. In particular, hereby contaminated surface layers removed on concrete floors, however Even entire runways at airports are machined to improve grip to increase the landing strip. The structure of such processed surface gives an impact and scratch image.
  • Tillage equipment are as Further developments, for example from EP-A-0'098'798, EP-A-0'241'417 or US-A-3'063'690 are known.
  • a road milling machine known with is equipped with two driven rotor rollers, in which machining pins are let in.
  • the corresponding editing image is a pure scratch picture.
  • the latter device has especially for removing road markings and Asphalt bumps proven. One can on concrete surfaces do not use such a device.
  • DE-A-2'151'190 is a surface processing device according to the preamble of claim 1 known.
  • This device designed for grooving concrete slabs, shows an axis, which is supported on both sides in the housing and on which seals a hollow shaft driven from the outside on both sides and provided with rolling bearings, runs.
  • the present invention has for its object a To create device of the type mentioned that a quieter Run as the devices with hammering results and enables an extremely large removal depth in one pass, one in the axial and radial directions absolutely correct storage and simple, pluggable interchangeability the rotor drum must be guaranteed.
  • the bottom view of the mobile tillage implement shows its most essential components.
  • the actual Drive consisting of a motor and the transmission means, namely the V-belts are not essential to the invention here omitted. Also the drawbar with the reference number 0 is only recognizable in the beginning.
  • the entire mobile device stands on its four wheels 1.
  • the two in the direction of thrust front wheels 1 are on a rigid axle 2 between the two side walls of the housing 4 mounted.
  • the two in Direction of thrust rear wheels 1 are on a rear, height-pivotable Axis 3 mounted.
  • Between the two side walls of the housing 4 supports the rotor shaft 5.
  • On the rotor shaft 5 stores the one shown in detail in FIG Rotor drum.
  • the drive side is in the side wall of the housing 4 drilled a hole in which a bearing housing 6th fits, which itself by means of screws on everyone Sidewall is screwed on.
  • the rotor shaft 5 holds with a snug fit in the two ball bearings 8 and passes through the bearing housing 7, so that a pin remains on which a multiple V-belt pulley Finds space.
  • an axial bearing disc 9 which presses a lock nut 10
  • the rotor shaft 5 is axial secured.
  • the rotor drum consists essentially of a hollow shaft 20, on which a fixed flange 21 is welded on one side is.
  • the fixed flange 21 has uniformly distributed on the circumference Threaded holes and through holes.
  • Threaded holes In the threaded holes are holding rods 22 screwed in parallel to Extend hollow shaft over its entire length.
  • On these support rods 22 are in an alternating order a large number of diamond cutting discs 23 and spacer rings 24 lined up.
  • the maximum working width of the rotor is therefore slightly less than the length of the hollow shaft 20. Both the Diamond cutting discs 23 and the spacer rings 24 must have corresponding holes, of course which the holding rods 22 pass through.
  • a counter flange 25 is placed, the by means of nut 28 with the interposition of spring washers 27 Package of diamond cutting discs and spacer rings firmly pressed together.
  • the counter flange 25 also has one Anti-rotation device 26 in the form of a pin, which is secured against rotation Storage of the counter flange 25 on the hollow shaft 20 guaranteed.
  • using a lock ring 21 the hollow shaft 20 secured axially on the rotor shaft 5.
  • the hollow shaft 20 is also on the drive side, both with respect to axial as well as radial movements with respect to the Rotor shaft 5 secured.
  • a stop flange 34 is used for this purpose, which is secured by means of a wedge 35.
  • drive pins 36 are held by means of a press fit, whose projecting free end in the fixed flange 21 on the Hollow shaft 20 can be plugged in.
  • the use of diamond cutting discs requires both an axial as well Radial play-free storage of the entire drum. This is the only way be made sure that while working on the cutting discs do not act on forces that lead to their breakage would. Such play-free storage is not absolutely easy to achieve if on the other hand a simply pluggable Interchangeability of the rotor drum can be guaranteed should.
  • the bearing of the rotor pin 14 presents a partial problem in the ball bearing 13. Here the game was through the installation an O-ring 16 caught.
