Definitions

  • the present invention relates to a rear-loading road milling machine as defined in the preamble of claim 1.
  • the publication US-A-4,186,968 While it describes a stabilizer or recycler and not a rear loader road milling machine, it does in itself show the features of the preamble of claim 1.
  • the known road milling machines essentially have the structure described below.
  • the road milling machine comprises a chassis which is supported on wheels or track drives. Furthermore, a milling drum is provided in the chassis, which is arranged within a roller housing, which is open downwards, ie in the direction of the road surface.
  • the known road milling machines In order to transport away the milled material, which is referred to below as milled material, the known road milling machines often have a transport device, via which the milled material can be fed to an accompanying truck with a corresponding loading area. If the milled material is fed to the truck via the rear of the road milling machine, this is referred to as a rear loader, while a front loader is used when the milled material is transported away to the truck via the front of the road milling machine.
  • the known road milling machines are lowered relative to the road surface, so that the rotating milling roller protruding from the roller housing engages with the road surface comes, with the lowering is usually done by lifting the wheels on which the chassis of the road milling machine is supported.
  • stripping devices In order to prevent the milled material from being thrown out towards the rear, that is to say counter to the direction of travel, stripping devices are used which essentially consist of a plate-shaped scraper, which is arranged behind the milling drum and whose essential task consists in milling on the milled surface strip left behind milled material, so that it can be fed to the transport device and does not remain on the machined surface.
  • the area proves to be problematic in the direction of travel in front of the milling drum.
  • rubber aprons have been developed which extend downwardly from a front part of the roll housing.
  • Such rubber aprons are flexible, so that they can deform depending on the lowering of the road milling machine and thus the milling depth.
  • the said rubber aprons should always rest against the road surface during the milling process, regardless of the depth of cut, so that no opening remains between the front part of the roller housing and the road surface.
  • the disadvantage is that the aprons mentioned offer, in particular at low cutting depths - in practice, only an insufficient seal against the ejected milled material.
  • the aprons tend to deform in a wave, so that a dense system is not given.
  • the aprons are subject to high wear.
  • shield assemblies have been developed in which a rigid, mostly metallic shield can be guided in vertical guides perpendicular to the road surface to be processed in front of the opening between the front part of the roll housing and the road surface.
  • the known shields are adjustable depending on the milling depth in height, the setting is achieved via plug-in bolts or the suspension on a chain.
  • the US-A-5,893,677 describes a stabilizer or recycler.
  • Stabilizer or recycler are used in the open field without personnel in the work area.
  • the rear wheels drive through the loose material thrown up by the machine.
  • a loss of material does not matter, as a loading does not take place.
  • the well-known recycler or stabilizer has a front in the direction of travel and a rear flap in the direction of travel.
  • the front flap always remains open in order to prevent tilting of the road surface when it is uneven or, in the case of loose ground, to avoid heaping up the ground in front of the roller housing.
  • the rear flap is brought to a height which makes it possible to evenly remove the mix at a certain height. Therefore, both flaps are adjustable in height by means of hydraulic elements.
  • the present invention is therefore based on the object, a rear-load road milling machine with a sealing device for pointing in the direction of travel opening between the front part of the roller housing and the road surface create, which ensures a safe protection against forwardly thrown milled material in compliance with the predetermined feed of the milling drum.
  • the road milling machine according to the invention is designed as a so-called rear loader, ie the milled material is removed via the rear of the road milling machine via a corresponding transport device.
  • the road milling machine has a milling drum, which is arranged in a downwardly open roller housing. A pointing in the direction of travel opening between a front Part of the roll housing and the road surface can be closed with a sealing device.
  • the sealing device can be adjusted in height. According to the invention, the sealing device for height adjustment can be pivoted about an axis in the direction of travel in front of the milling drum.
  • the sealing device Due to the pivotability of the sealing device about an axis which is arranged in the direction of travel in front of the milling drum, it is possible to pivot the sealing device to the road surface, so that no gap between the front part of the roll housing and the road surface remains, by the milled material could be thrown out in front.
  • the sealing device according to the invention can not tilt with the road surface, in contrast to the known vertically displaceable baffles. Rather, the sealing device is pulled by the special suspension sliding over the pavement so that it follows the course of these bumps by swiveling back and forth in unevenness, such as ripple of the road surface or by existing milling tracks. An interruption or even blocking of the feed by tilting is thereby excluded.
  • the sealing device according to the invention has advantages.
  • the contact pressure on the pavement of the sealing device is no longer dependent on the depth of cut, as is the case with the deformable rubber apron. Rather, a constant contact pressure can be applied to the road surface with the sealing device of the road milling machine according to the invention regardless of the depth of cut, so that even at low cutting depths ejection of milled material is prevented.
  • the sealing device has an impact shield facing the opening.
  • a baffle plate may for example consist of metal, as well as the roller housing.
  • the sealing device has a swivel arm.
  • the swivel arm is attached on the one hand to the baffle plate and on the other hand extends to the axis about which the sealing device can be pivoted.
  • two or more pivot arms can be provided instead of a pivot arm.
  • an arrangement could be useful in which two pivot arms are provided, one end of which extends in each case to the lateral ends of the baffle plate and the other end is rotatably guided on the ends of the axis.
  • the baffle plate has a circular arc-shaped cross-section. It is particularly preferred here that the radius of the circular arc-shaped cross section corresponds to the distance between the axis and the baffle plate. In this way, the baffle plate at each point the same distance from the axis. Thus, the baffle plate regardless of the pivot position always be in frontal contact with the front part of the roller housing without additional tools would be required to compensate for a change in distance between the roller housing and baffle plate.
  • the sealing device can be pivoted about the axis while permanently forming a contact line with the front part of the roller housing.
  • an elongated sealing or stripping element is provided on the roller housing along the contact line in a particularly preferred embodiment.
  • This may be, for example, a rubber band, wherein the sealing or stripping element should advantageously be replaceable in order to replace worn elements with new ones.
  • the sealing device has at least one skid facing the road surface.
  • One or more skids allow easier sliding of the sealing device over the pavement. It is particularly advantageous if the skate or skids extend in the direction of travel of the road milling machine.
  • the skid extends in a preferred embodiment of the invention over the entire width of the sealing device.
  • the skid is curved downwards. In this way it is ensured that the skid rolls during pivoting over its entire length on the pavement and not abruptly rests only on one of its ends, as would be the case with straight skids. Thus, a uniform wear on the skids is guaranteed, which leads to an increased life of the skids.
  • the sealing device can be pivoted to form a contact line with the road surface against the pavement.
  • a sliding strip is provided in a further preferred embodiment along the line of contact of the sealing device with the road surface.
  • the skid and / or the slide bar can be replaced to replace worn skids or wear strips by new skids or slide strips can.
  • the skid and / or slide bar made of hardened material having a greater hardness than the material of the other components of the sealing device, so that the standing in contact with the pavement skid or sliding strip is subject to low wear.
  • the sealing device can be pivoted against the road surface at a predetermined pressure. This has the advantage that the sealing device is not pivoted upwards even with any obstacle, however small, such as parts of milled material remaining on the road surface. Rather, the softer obstacles are crushed or crushed by the applied pressure.
  • the pressure itself may be applied, for example, by a spring element which acts on the sealing device or simply by the weight of the sealing device.
  • sealing device in addition to the above-mentioned embodiment, can be pivoted back when the predetermined pressure is exceeded.
  • the sealing device follows the harder or larger bumps and obstacles, but without lifting off the road surface.
  • a constant hydraulic pressure can be set, wherein the hydraulics allows a pivoting back of the sealing device when the predetermined pressure is exceeded. This can be done for example by means of a pressure relief valve within the hydraulic system.
  • the sealing device can be locked in different pivot positions.
  • the sealing device can be pivoted back into a transport position and locked, in which the sealing device does not rest on the road surface.
  • the locking can be done by conventional means, such as a chain suspension or staking with bolts.
  • the locking can also be done by means of hydraulics.
  • the road milling machine 2 has a chassis 4, which is supported in the present embodiment on three wheels 6, 6, 8, wherein the two rear wheels 6, 6 (only one is in Fig. 1 seen) laterally in the region of the rear and the front wheel 8 is arranged centrally in the region of the front side of the road milling machine 2.
  • the rear wheels 6, 6 are height-adjustable by means of a hydraulic, wherein the steering of the road milling machine 2 via the front wheel 8 takes place, which can be rotated about a vertical axis A.
  • a road milling machine 2 in place of the wheels 6, 6, 8 are also worn by crawler tracks.

  • roller housing 16 Below the driver's station 10 is a roller housing 16, which is thus also arranged in the region of the rear of the road milling machine 2.
  • the roller housing 16 is a downwardly, ie in the direction of the road surface 18, open housing in which a milling drum 20 is arranged, wherein the longitudinal axis of the milling drum 20 extends transversely to the direction of travel, in Fig. 1 is shown on the arrow a.

  • a sealing device 26 is provided, which in particular with reference to the Fig. 2 to 4 is explained in more detail.
  • the roller housing 16 has a forward direction in the direction of a part 28, which is usually formed by a continuous plate. Since this front part 28 may not come into contact with the road surface 18, which would inevitably lead to damage of the front part 28 or obstruction of the feed in the direction of travel, remains between the front part 28 and the pavement 18 always one forward directed opening B. This opening B is closed by the sealing device 26 according to the invention.
