Definitions

  • the invention relates to a roller equipped with tools for mobile machines, especially for road and path construction as well as a forestry mulcher, on the lateral surface of which tensioning boxes along at least one helical track are welded and the tools in the boxes are clamped.
  • the invention also relates to a Roller of this type, with the tools in the clamping boxes Interchangeable holders are clamped, with one on each interchangeable holder up to three wedge (s) and in each clamping box mounts for the Wedge (s) of the change holder and the change holder and the clamping box by means of a clamping device in mutual wedge engagement are held.
  • breaker elements distributed over the circumference of the roll and in the transverse direction of the roll are attached to the lateral surface of the roll.
  • the crusher elements are inserted into recesses formed on the lateral surface and are detachably fastened in the roller with a bolt.
  • the chisels are used, for example, to mill off a road surface made of asphalt or concrete, while the crusher elements are intended to prevent coarse milled material from settling between the chisel holders and, by interacting with the crusher bar, serve to break this coarse material to a desired maximum grain size.
  • the ratio of the number of the two tools on the roller can only be changed by the fact that the holders and / or recesses for the two types of tools remain partially empty, which, however, impairs the performance of the roller.
  • Another disadvantage of the known milling crusher roller is that the crusher effect due to the interaction of the crusher elements with the crusher bar is insufficient.
  • the present invention has for its object a Tooled roller for mobile machines, in particular for road and path construction, to create with the different Tasks in the field of milling and / or Breaking different materials can be solved.
  • Experimental milling and / or crusher tasks with one and the same roller approach and / or optimize performance. In doing so a systematic change in what can be achieved with the machine Milling, lifting and breaking action may be possible without this Roller change is required, and the change in effect should not affect performance (or tool density on the roller). Further advantages result from the following description.
  • Roll are the tools of at least one type of tool in one piece educated.
  • These one-piece tools are generally flat tools, which prefers a lifting function and / or in cooperation have a crusher function with a crusher bar.
  • This Tools generally have a fixed arrangement on the roller, i.e. in contrast to picks, they are not about their longitudinal axis rotatably arranged.
  • Axial symmetrical, two-part are preferably in the clamping boxes trained tools and non-axially symmetrical, one-piece Tools used.
  • the axially symmetrical two-part Tools are generally round shank chisels, e.g. on milling crusher rollers perform the milling work on a road surface and are rotatably supported for uniform wear. Tool in the sense of the present invention is therefore not only the axially symmetrical Picks, but also the associated tool holder, in which the picks can be rotated.
  • the non-axially symmetric, one-piece tools are generally Tools that do the lifting and breaking work. In general, however, it can be said that the different types of tools usually perform several functions.
  • each clamping box formed for the wedge (s) of the clamping part there are also one to three exceptions (n) in each clamping box formed for the wedge (s) of the clamping part and are the clamping part of the tool and the clamping box by a screw held in mutual wedge engagement. Through this mutual Wedging the tool with the clamping box will loosen the Tool in the clamping box almost completely avoided. Even if yourself the tool should loosen over time by tightening the Screw and thereby further pulling the wedges into the wedge holders be eliminated again.
  • This embodiment also includes Variant in which the wedge (s) are molded onto the clamping box are and the wedge holder (s) are formed in the tool.
  • the tool or the clamping box has two wedges or wedge holders.
  • each clamping box contains two receptacles that interact with the wedges.
  • a wedge connection By arranging a wedge connection on both sides becomes a stable interlock between the clamping part of the tool and the tension box is reached.
  • One of the two wedge surfaces of each wedge connection expediently runs parallel to the screw axis.
  • the tools are expedient at least one type of tool cannot be removed from the tool holder or immovable, but releasably connected.
  • This type of tool is generally a flat or chisel chisel that holds its position to maintain the direction of roll rotation in operation to its preferred The task of lifting and breaking the milled material to be able to fulfill.
  • These tools can then be attached to the change holder be welded or screwed on in a torque-proof manner.
  • Rolls with or without interchangeable holders are the heights h of the tools of the different types of tools essentially the same.
  • the axially symmetrical tools namely the round shank chisels and the non-axially symmetrical tools, e.g. the flat chisel or chisel chisel, same height.
  • the tools are expedient of the two (and possibly other) tool types of round shank chisels and flat chisels.
  • the tools of two or more are expedient Tool types rotatable picks and immovable held flat chisels. With the same height of both types of tools Each type of tool also contributes to the work that the other type of tool performs, i.e. the flat chisel also perform milling work and the round chisels work together with the crusher bar also crusher work.
  • the slope a / b of the helical is preferably Track along which the clamping boxes are arranged in the area from 0.22 to 1.
  • the roll shell is therefore available with or without a separate version Interchangeable tool holder larger than known milling crusher drums, such as the one they have are shown for example in DE 43 24 234.0.
  • Figure 1 shows on a segment of the roller 2 four clamping boxes 3 welded along a helical track onto the roller surface 2 a .
  • an interchangeable holder 4 is clamped in a manner which is explained below using the Figures 3 to 5 is described in more detail.
  • the left change holder 4 is set up for the rotary holder of a round shank chisel 7 and for this purpose contains a receiving bore 6 for receiving the chisel shank, which is indicated in FIG. 3.
  • the right-hand change holder 4 in FIG. 1 has an angular tool holder 6 with a threaded hole 4 c for screwing on a tool 28 with a hard metal plate 29 by means of screw 30.
  • this change holder is designed like the change holder 4 for the round shank chisel 7 and with two molded wedges 10 engages with corresponding wedge-shaped recesses 11 of the tensioning box 3, as can be seen in more detail in FIGS. 3 to 5.
  • the tools 31 are designed in the same way as the change holder 4, so that the positions of the tools 31 and the change holder 4 equipped with tools 7 and 28 are interchangeable.
  • the tool parts 31 ' also have wedges 10 formed symmetrically with respect to their central plane, which engage in corresponding recesses 11 in the clamping boxes 3.
  • the heights h of the tools 7; 31.32; 28.29 above the surface 2 a of the roller equal to each other.
  • the figure shows four different tools on the roller for the purpose of their explanation. In practice, the roller is generally only equipped with two or three different tools.
  • FIG. 2 shows four sections of rolls joined together, which are equipped with differently mixed tools.
  • Everyone Section includes a helical turn of track 33.
  • the cases shown are five tension boxes 3 on each turn arranged, in the change holder 4 with picks 7.16 or inserted by means of screw 30 double-edged flat chisels 28, 29 are.
  • the slope a / b of the helical Lane 33 is about 0.28.
  • Their key figures are above the clamping boxes entered under which the coordinates of the clamping box positions as a table in terms of angle and axial distance from reference planes are recorded (not specified).
  • Figure 2 are double-edged flat chisels 28.29 shown of considerable overall width (e.g.
  • the shown double-edged flat chisel at least in part single-edged flat chisel (chisel chisel) to be replaced only a cutting width of e.g. Have 10-12 mm.
  • FIGS. 3 to 5 there is the quick-change holder system according to the invention for the round shank 1 essentially one box 3 welded onto the roller 2, one into the box 3 in in the manner described below releasably clamped change holder 4 and a clamping screw 5.
  • the interchangeable holder 4 contains one as a cylindrical one Bore-shaped receptacle 6 for the shank 16 of the round shank chisel 1.
  • the chisel 1 is in the receptacle 6 with the help of a Spring sleeve releasably held, which is not shown in Figure 3 and is described in more detail in DE 100 44 369.9 for FIG. 7.
  • the diameter the chisel head 7 at its base is large enough to be prone to wear Cover surface 8 of the chisel holder.
  • the interchangeable holder has 4 on both sides to the central plane 9 symmetrical, wedge-shaped formations 10 in correspondingly wedge-shaped recesses 11 in the wings the box 3 intervene.
  • the interchangeable holder 4 can therefore i.e. in the direction of arrow Y, are inserted into box 3 until the wedges 10 come into contact with the wedge-shaped recesses 11.
  • a downwardly drawn end wall 12 with a threaded bore 12 a is formed between the projections 10 at the front.
  • the box 3 is pulled down in the middle in the rear and provided with a through-hole 3 a with a countersink 3 b .
  • the interchangeable holder 4 is pulled with its wedges 10 into the wedge recesses 11. This results in a low-wear connection between the change holder 4 and the box 3 with a compact construction of the unit.
  • the interchangeable holder 4 can be loosened from the wedge connection 10, 11 even in the case of heavy contamination by light hammer blows against the back 4 a .
  • the interchangeable holder 4 can be wedged against the front side 4 b by light hammer blows. Any contamination that may be present in the wedge receptacles can be pushed outwards through the transverse bores 14. A worn change holder 4 can therefore be easily replaced on the construction site.
  • a tool 15 is used.
  • the chisel 1 can then be easily driven out of the receptacle 6 and replaced by light hammer blows on the chisel shaft 15 lying against the chisel shaft base.
  • the box 3 is provided on both sides of the central level 9 with a skid 3 d .
  • the box 3 is welded to the roller 2 along these runners 3 d .
