Definitions

  • the invention relates to a mobile surface processing device with two counter-rotating, motor-driven rotor cages with a horizontal axis, on the cage bars of which a plurality of processing elements are lined up, and that height-adjustable wheels are arranged in front of and behind the rotor cages.
  • Devices of this type are known, for example, from US Pat. No. 252,880 and are designed both as hand-held devices and as larger devices which can be moved on rollers.
  • the rotor can be driven both by an electric motor and by an internal combustion engine.
  • An air motor can also serve as the drive.
  • the devices are used for surface processing, such as removing rust from larger areas, removing old paint, cleaning dirty concrete floors, etc.
  • the processing remains limited to the surface, the processing depth is adjustable but small.
  • the actual processing takes place through the processing elements, such as lamellae, lined up on the rotor cage bars.
  • the known devices mentioned above have only one rotor cage. This has the disadvantage that the machining force acts in response to the feed movement, so that the device tends to move automatically in one direction.
  • the invention has for its object to provide a surface processing device of the type mentioned, in which the reaction force perceived as a disadvantage can be used desirably.
  • the invention solves this problem in that the two rotor cages are rotatably mounted in a chassis that is provided with wheels that are each arranged at the lower end of a two-armed pivot lever, that a connecting rod is articulated at the upper ends of these pivot levers, and that the upper arms of the two-armed pivot lever together with the connecting rod and the connecting line of the pivot axes form an angle-adjustable parallelogram, the angle adjustment causing a change in the relative position of the chassis relative to the surface to be worked.
  • the device shown in FIG. 1 resembles a lawn mower with motor drive.
  • the device is equipped with an internal combustion engine M. This is attached to the top of the chassis, which is generally designated 1.
  • the chassis is provided with two rear wheels 11 and a front wheel 12.
  • a steering / pushing device 2 is rigidly attached to the rear of the chassis and projects upwards at an angle of approximately 45 °.
  • At the upper end of the device 2 'two steering handles 21 are attached, with which the device is steered.
  • the height of the wheels 11, 12 or the height of the chassis above the surface F to be machined can be adjusted by means of a lever 22. With the help of the rotary knob 23, the height adjustment of the front wheel 12 with respect to the two rear wheels 11 can be adjusted for itself.
  • the two rotors R 1 , R 2 driven in opposite directions by the motor M are rotatably mounted inside the chassis 1.
  • the bearings are attached to a removable plate 13. If the plate, which is attached to the chassis 1 by means of screws, is removed together with the bearings attached to it, the two rotor cages, together with the fins attached to them, can be removed and replaced or revised.
  • the machining bodies are subject to a certain amount of wear and tear and must be replaced or re-equipped after a certain period of operation.
  • Rotor R 1 is shown in view - rotor R 2 in section.
  • Each rotor has a cage that includes two side plates 30, a hollow hex shaft 31, and four cage bars 32 extending between the side plates 30.
  • One of the two side walls 30 can be detached from the cage bars so that the processing bodies can be applied to the cage bars 32, or removed and replaced.
  • the hollow hexagon shafts 31 can be pulled off or fitted onto corresponding hexagon drive shafts which are fixedly mounted on a chassis side.
  • the processing elements L can have different shapes depending on the surface to be processed. All elements intended for a device have the same external machining diameter D and a bore with the same diameter d 1 that is larger than the diameter d of the cage bars 32 on which they are lined up.
  • the elements L 1 have the shape of pentagonal lamellae which are fitted with hard metal.
  • the processing elements L 2, on the other hand, are triangular lamellae that only have hardened tips.
  • Rotor R 1 is equipped, for example, with square blades L 3 with hard metal inserts, and rotor R 2 has machining elements L 4 in the form of carbide-tipped cutters.
  • Figure 2 shows the rotors during operation, the machining elements, as far as their bore allows, are pushed radially outwards by the centrifugal force.
  • the arrows 33 and 34 indicate the direction of rotation. This is advantageously chosen such that it is directed away from one another on the side of the surface to be processed. As a result, the material removed from the surface, i.e. the waste or chips, is thrown outwards. If the direction of rotation of the rotors on the side of the surface to be machined were directed towards one another, the removed material would accumulate between the rotors.
  • FIG. 3 The parts used for height adjustment are shown in FIG. 3.
  • the same parts as in Figure 1 are provided with the same reference numerals.
  • the wheels 11 and 12 are each attached to the end of a two-armed lever 14, 15 which can be pivoted about a fixed axis 16 or 17.
  • the other ends of the levers 14, 15 are connected to one another in an articulated manner by a connecting rod 18, so that they form an articulated parallelogram.
  • a rod 24, which leads to the adjusting lever 22, is articulated on the lever 14. This can be pivoted about an axis 25 attached in part 2.
  • An adjustment of the lever 22 therefore leads to an angular adjustment of the joint parallelogram 14, 15, 18 and thus to a height adjustment of the chassis 1 with respect to the surface F, which leads to a change in the machining intensity of the rotor R 1 , R 2 equipped with lamellae. So that this height adjustment can be carried out by means of the relatively short lever 22, a weight compensation spring (not shown for the sake of clarity) is attached, which is designed as a tension spring and extends from the eyelet 19 on the chassis to the rod 24.
  • a threaded pin 43 is rotatably but axially fixed, the threaded part of which is screwed into a nut thread in the connecting rod 18.
  • Rotation of the threaded pin in one direction or the other therefore results in an increase or decrease in the distance between the joints 40, 41.
  • the chassis lowers further and the machining becomes more intensive. In this way, the machining strength can be set very finely and sensitively from zero to the maximum.
  • the device behaves neutrally and can be moved forwards or backwards over the surface to be worked with the aid of the two links 21.
  • the front wheel 12 can be adjusted so that the device tends to drive forward or backward automatically. If the device is to drive forward, the front wheel 12 is raised a little with respect to the rear wheel pair 11. As a result, the effect of the front rotor R 2 is less than that of the rotor R, so that its reaction force predominates and pushes the device forward. If a backward drive is desired, the procedure is reversed and the wheel 12 is lowered a little. The wheel 12 can be raised or lowered by turning the knob 23.
  • an electric motor or a compressed air motor can also be used.
  • the exhaust air of the same can be used to blow away the abrasion or the chips.
  • a chain could also be used.
