Definitions

  • the invention relates to a rotor box for a milling machine, in particular floor and / or road milling machine, according to the preamble of claim 1.
  • the invention further relates to a milling machine, in particular ground and / or road milling machine, in particular a road milling machine or a trencher, at least having such a rotor box.
  • Such a rotor box has an ejection opening, from which the milled by the milling rotor soil material (hereinafter referred to as milled material) z. B. can be ejected on a wegmixdes conveyor belt.
  • this ejection opening does not extend over the entire axial length of the milling rotor, so that the milled material in the rotor box, for example, has to be moved out of the lateral areas toward the ejection opening.
  • This happens z. B. by snail-shaped milling cutter arranged on the Fräsm facedel Glan, the milling chisel or Fräsm facedelhalter favor the transport of the milled material in the rotor box due to an angle of attack.
  • the disadvantage here is a heavy wear on the milling rotor and in particular on the cutting tools and the Fräsm Jardinelhaltern, as well as on the rotor box itself.
  • the invention is therefore based on the object to improve the transport of milled material inside the rotor box.
  • the rotor box according to the invention serves as housing at least one milling rotor provided for removing soil material on a milling machine, in particular ground and / or road milling machine (both designations are used interchangeably below). It is envisaged that the wall of this rotor box, i. H. at least the inner wall of this rotor box, at least in a section with an enlarged distance from the milling rotor is designed to allow targeted in the area of the rotor box targeted routing of the removed soil material or Fräsgut from the milling rotor.
  • An enlarged distance of the wall to the milling rotor is understood in particular that with respect to the direction of rotation of the milling rotor, the wall before and after the relevant section, which is meant with respect to the milling rotor in particular a peripheral portion is formed with a smaller distance from the milling rotor.
  • the wall of the rotor box according to the invention with respect to the circumferential direction of the lined milling rotor has a varying distance from the milling rotor. This measure leads z.
  • the milled material can be more easily detached from the rotating milling rotor and that the milled material solved by the milling rotor can almost unimpaired describe a trajectory within the rotor box.
  • the relevant section of the wall which is formed with an enlarged distance from the milling rotor, is therefore ideally designed with regard to a Ablöstician of the milled material from the milling rotor and with respect to the trajectory of the detached milled material.
  • This measure leads z. B. but also that the moving in the rotor box milled material in its movement through the rotor box is significantly less affected (as in the known from the prior art rotor boxes) by contact with the milling rotor or the wall of the rotor box.
  • the portion of the wall, which has an enlarged distance from the milling rotor extends over the entire axial length of the milling rotor.
  • the portion of the wall, which has an enlarged distance to the milling rotor, with respect to the milling rotor is formed approximately opposite the ejection opening of the rotor box. This relates approximately to the transition region from the rotor box ceiling to the rotor box rear wall.
  • the milling rotor between the portion of the wall, which is formed with an enlarged distance from the milling rotor, and the milling rotor at least one separating device is arranged, in the relevant inner region of the rotor box a renewed contact of the weggefeiteten Milling material (eg. By kickback or Rebounding from the wall) with the milling rotor prevented.
  • this separator is arranged so that almost no material between it and get the milling rotor.
  • the passage-like region between the separator and the milling rotor thus remains substantially free of milled material, which is advantageous in several respects.
  • the rotor box according to the invention has many advantages.
  • An advantage is z. As can be seen in the fact that both the milling rotor, the chisels and the Fräsm adoptedelhaltern, as well as the rotor box or its wall and in particular inner wall less wear occurs.
  • Another advantage is the fact that in the rotor box according to the invention in principle more milled material can be moved, whereby the milling performance of the ground milling machine can be increased.
  • the separating device is designed as a rigid, in particular wing-like and axially extending longitudinal profile, which preferably has a teardrop-shaped cross-section.
  • the separating device preferably extends over the entire axial length of the milling rotor and extends from one side wall to the opposite side wall of the rotor box.
  • a support and / or stiffening can be provided over the axial length of the separating device.
  • the separating device is interchangeable and in particular in its orientation is arranged adjustable in the interior of the rotor box.
  • it can also be provided to equip the separating device at its front side with respect to the direction of rotation of the milling rotor with an impact protection and in particular with an exchangeable impact protection, which functions as wear protection and / or wear part.
  • a particularly preferred embodiment of the invention provides that a Wasserberieselungs- and / or water jet device is arranged on the separator, which acts on the rotating Fräsrotor with water.
  • This device is preferably arranged on a milling rotor side facing the separator. This measure means that as a result of the routed milled material and for the purpose of cooling and / or cleaning an effective irrigation or irradiation of the cutting tool and the Fräsm adoptedelhalter can be done so that their wear is reduced. If necessary, the water must be applied at a high pressure to allow a good cleaning.
  • the water sprinkler and / or water jet device has z. B.
  • a plurality of water jet nozzles which are arranged in the axial direction along the separator, which in principle can also be used on other means for spraying the water, for example on perforations, etc.
  • the water jet nozzles used can be varied extensively within the scope of the invention. For example, it is possible to use water jet nozzles that produce a linear bundled jet of water during operation. Alternatively, however, water jet nozzles have proven useful, from which the water jet at least partially emerges cone-shaped or fan-shaped. Combinations are possible. Another significant variation is in the specific arrangement of the water jet nozzles or the orientation of the jet relative to the milling rotor.
  • the nozzles in such a way that their water jet is directed in the plane of rotation of the milling rotor on the milling rotor.
  • the water jet can to tilt perpendicular to or hit in or against the direction of rotation on the milling rotor.
  • the orientation of the water jet refers to the cone axis or to the bisector between the two outer legs of the fan, for water jet nozzles with a substantially linear water jet to the longitudinal axis of the water jet.
  • the water jet nozzles can alternatively also be tilted out of the plane of rotation and arranged on the separating device, up to arrangements in which the water jet runs parallel to the axis of rotation and / or horizontally.
  • the water jet with its surface line or with its outer fan shank is specifically aligned with at least one chisel tip of a chisel rotating with the milling rotor so that it has at least one rotating chisel tip reliably impinged by the water jet obliquely at each rotor circulation and, for example, cleaned and / or cooled.
  • this water sprinkler and / or water jet device is also designed to apply water to the engagement region of the milling rotor in the soil material.
  • the rotor box has separate Wasserberieselungs- and / or water jet devices that act on these faces of the milling rotor with water.
  • These devices can, for. B. be arranged on the lateral inner wall of the rotor box.
  • Also suitable for this purpose is in particular the use of the above-mentioned tilted water jet nozzles.
  • Fig. 1 shows in plan view a rotor box 100 in which a milling rotor 40 (see Fig. 2 and Fig. 3 ) is arranged.
  • the rotor box 100 has a wall formed from a sheet metal material, which comprises a rotor box cover 10, a rotor box rear wall (rear wall) 20 and an ejector 30 with an ejection opening 31.
  • the soil material (milled material) removed by the milling rotor 40 must be conveyed within the rotor box 100 to the ejector 30. This happens z. B. by snail-shaped milling rotor 40 arranged Fräsm facedel Glan.
  • the disadvantage here however, a heavy wear, which is caused by the milled material.
  • the wall of the rotor box 100 is formed at least in a section with an enlarged and in particular large distance from the milling rotor 40, which allows a targeted routing away of the removed material from the milling cutter milling cutter 40. This will be related to the following Fig. 2 explained.
  • Fig. 2 shows a section through the rotor box 100 according to that in the Fig. 1 specified cutting course II-II.
  • the milling rotor is at 40 and the bit engagement circle of the attached to the outer shell milling cutter is designated 41.
  • the milling rotor 40 rotates in the indicated direction R, wherein the cutting tools detach the soil material B to be removed and take it along as the milled material.
  • a portion of the entrained milled material is ejected through the ejection opening 31 of the ejector 30, which is indicated by the arrow A. Supporting this can be arranged on the milling rotor 40 so-called launcher (not shown). However, a further portion of the entrained milled material dissolves later due to centrifugal force from the milling rotor 40 and thus remains in the interior of the rotor box 100.
  • the ejection opening 31 opposite wall portion of the rotor box 100 is formed with a relatively large distance from the milling rotor 40.
  • This section extends in the transition region from the rotor box ceiling 10 to the rotor box rear wall 20.
  • a targeted routing of the material to be cut by the milling rotor 40 is made possible.
  • the milled material 40 detached from the milling rotor 40 is hardly affected in its trajectory by any contact with the wall of the rotor box 100 and / or with the milling rotor 40, which is indicated by the arrow B.
  • the wall (or at least the inner wall) of the rotor box 100 is formed in the relevant section with an enlarged distance to the milling rotor 40, so to speak, a free trajectory of the material is made possible (see arrow B).
  • Abrasive wear by abutting milled material on the wall of the rotor box 100 and / or on the milling rotor 40 is largely prevented.
  • the rotor box rear wall 20 is reinforced (for example, made of a thicker material) designed to withstand shocks and resulting interactions can.
  • the milled material guided away from the milling rotor 40 finally returns to the engagement region of the milling tool.
  • the wall of the rotor box 100 occupies an enlarged distance from the milling rotor 40 in the relevant section, the rotor box 100 according to the invention nevertheless has a compact and lightweight design.

  • the separating device 50 is formed as a rigid longitudinal profile and extends parallel to the longitudinal axis or axis of rotation L of the milling rotor 40 (see Fig. 3 ).
  • the separating device 50 prevents the milled material guided away from the milling rotor 40 from coming into contact again with the milling rotor 40 and forms a passage 60 (between the separating device 50 and the milling rotor 40), which remains substantially free of milled material.
  • the tip of the cross-sectional teardrop-shaped separator 50 has opposite to the direction of rotation R of the milling rotor 40, whereby the risk of collision of milled material is reduced.
  • the separator 50 is replaceable and in particular also arranged adjustable, so that z. B. whose distance from the milling rotor 40 and / or their inclination can be changed.
  • a Wasserberieselungs- and / or water jet device which acts on the rotating Fräsrotor 40 with water W. Since the passage 60 remains substantially free of milled material, the water W can impinge almost unhindered on the milling rotor 40, or on its milling cutter and Fräsm facedelhalter, which is shown schematically with the lines W.
  • the water W is used for cleaning and possibly also for pressure cleaning of the cutting tool and milling tool holder, whereby the milling performance is increased. Furthermore, the water W also serves to cool the cutting tool in the milling operation, so that the milling cutter cooled again in the soil material to be processed B can intervene. As a result, the wear of the cutting tools can be significantly reduced.
  • the cleaning and / or cooling of the chisel with the water W requires that near the milling rotor 40 a quasi-material-free space (passage 60) is created, which is accomplished on the one hand by the design of the rotor box 100 and on the other hand by the separator 50.

As a result, the rotational willingness of the cutting tool can be increased.
  • the water sprinkler and / or water jet device is formed from a plurality of water jet nozzles 71, which are arranged in the axial direction along the separator 50. This is very vivid in the Fig. 3 recognizable, in which the view into the interior of the rotor box 100 is given free. The representation of the Fig. 3 is also very good to see that the separator 50 is aligned parallel to the axis L of the milling rotor 40. From the cross-sectional view Fig.
