Definitions

  • the invention relates to a self-propelled milling machine for processing of ground surfaces, in particular roadways, according to the preamble of claim 1, such as a method for disposing of dusts and vapors generated during the milling process on a milling machine according to the preamble of claim 14.
  • Such milling machines are also referred to as road milling.
  • a Frontladerfräse is known for example from DE-A 39 03 482 or DE-A 38 31 161.
  • the known milling machines have a self-propelled chassis with a front wheel pair and a rear wheel pair.
  • the chassis carries a machine frame in which a milling drum is mounted transversely to the direction of travel.
  • the milling drum is usually surrounded by a housing in which the pointing in the direction of travel wall is designed as a cover plate with a passage opening for the milled material.
  • the rearward in the direction of travel wall is designed as a scraper and is pressed against the milled surface to seal the roller box to the rear to supply the milled material completely to the removal.
  • the processed from the milling drum material is dropped from the milling drum on a first conveyor belt, the processed material at the front end of the Milling machine transfers to a discharge belt, which is for transport to a loading area of a truck in the inclination and laterally pivotable.
  • the so-called rear loader is known for example from DE-A 34 05 473.
  • the passage opening for the milled material facing in the opposite direction of travel also designed as a scraper wall of the roller housing.
  • the milled from the milling drum material is transferred directly to the conveyor belt serving as a discharge belt, which is arranged at the rear end of the milling machine to convey it to a truck.
  • the discharge conveyor of the rear-loading router can be tilted and swiveled sideways.
  • the milling drum such road milling machines is equipped with chisel tools that form a conveyor coil that transports the milled material to the passage opening of the cover.
  • the invention is therefore an object of the invention to provide a milling machine of the type mentioned above, as well as a method for disposing of dusts and vapors, in which with less mechanical complexity and with higher efficiency during the milling process and the transport process resulting dusts and vapors can be sucked off and together with the processed material can be disposed of.
  • the invention advantageously provides for the suction device to be connected to a first channel section of the channel downstream of the first transfer point and to extract the air contaminated during milling essentially in the material transport direction in the first channel section, the contaminated air also being conveyed to the milling drum is sucked off.
  • the invention enables a simple construction, in which the structure of a milling machine does not have to be fundamentally changed, so that a retrofitting of existing milling machines is possible.
  • Extraction of contaminated air in the first section of the duct allows extraction near the largest source of contamination where dusts and vapors are generated.
  • dusts are generated by rupturing the soil surface and vapors due to the high temperatures of milling, e.g. when milling asphalt materials.
  • dusts in the area of the transport device can also be created by transporting the milled material.
  • the arrangement of the suction device in the first channel section of the transport device allows the application of a strong flow of air in the region of the milling drum and the first channel section, thereby preventing dusts or vapors from escaping at the milling drum or at the first channel section.
  • Dusts and vapors can therefore be reliably sucked onto the transport device in the working area of the milling drum and at the transfer point of the milling drum.
  • a major advantage is the improvement of the working conditions on the control station and in the vicinity of the milling machine and the low susceptibility of the transport device. In addition, the milled soil surface is left clean.
  • a significant advantage of the disposal of dusts and vapors on the discharge of the transport device is that at this point a dust is almost inevitable, since the milled material is dropped from a height of several meters on the back of a transport vehicle.
  • the invention provides in an advantageous manner that the dusts and vapors are disposed of exactly where the dust is inevitable anyway. There, for safety reasons, the stay is strictly prohibited.
  • the working area on the control station and next to the machine is free of dusts and vapors and especially of their breathable fractions.
  • the second channel section is separated by separating means from the first channel section for blocking an air flow, without obstructing a transport of the material.
  • the suction device has a suction channel connected to the first channel section and an axial fan integrated into the suction channel.
  • the contaminated air is disposed of from the first channel section via the suction channel, wherein the integrated into the suction channel Axial fan for a high negative pressure and a high air flow speed at the suction points provides.
  • Another advantage of the axial fan is that it can be integrated into the suction channel and therefore arranged to save space and at the same time can be arranged close to the suction points.
  • Another advantage of the axial fan is its dirt resistance and its self-cleaning effect. The high suction power not only allows breathing of breathable dusts and vapors, but also coarser dust particles.
  • the suction device disposed of the contaminated air at the point at which occurs anyway dust development due to the dropping of the milled material from the transport device.
  • the downstream end of the suction channel opens into an upper portion of the second channel portion of the channel formed by the transport device.
  • the downstream end of the suction channel opens into a second channel section, which is separated from the first channel section with separating means for shutting off an air flow, without the transport of the milled material being hindered. Accordingly, a subdivided channel is formed, which extends over the entire length of the transport device, the subdivisions being effected by the separating means, which on the one hand do not hinder the transport of the milled material and on the other hand prevent an air flow against the material transport direction. In this way, the channel sections are mutually sealed airtight to each other substantially.
  • the transport device has at least one conveyor belt with a conveyor belt, and that sealing means for the channel consist of hoods sealing against the conveyor belt or against the housing of the conveyor belt.
  • the hoods thus form together with the conveyor belt or together with the housing of the conveyor belt a closed channel, so that the milled material passes through the transport device circumferentially completely enclosed. In this way, no dusts or vapors can escape to the outside.
  • a second transport device can take over the milled material at the end of the first transport device at a second transfer point.
  • the transfer point between the first and second transport means is sealed with flexible sealing means fixed to at least one of the transport means. Smaller gaps are irrelevant, since both the first channel section and the lower part of the second channel section are under negative pressure, so that at any leaks no contaminated air can escape, but at most air is sucked.
  • the suction channel preferably enters the second channel section at an acute angle and just before the discharge end.
  • the entry angle enhances the injection effect, so that without an additional suction device and the lower part of the second channel portion is reliably sucked.
  • an agglomeration device is arranged behind the mouth of the suction channel in the second channel section.
  • the dusts and vapors can be agglomerated or condensed so that they can be disposed of together with the milled material.
  • the agglomeration device can consist, for example, of a water spraying device arranged at the outlet of the transport device. With the help of the water spraying device, the dusts can be bound and agglomerated and also the vapors are condensed.
  • At least one flexible flap which closes the first channel section of the transport device against air ingress against the material transport direction, is arranged downstream of and near the suction nozzle of the suction device.
  • the milled material can pivot the flap, while an air inlet is prevented against the material transport device.
  • the negative pressure in front of the flap thereby reinforces the seal by sucking the flap onto the milled material located on the conveyor belt.
  • the separating means is preferably provided on the first transport device.
  • the flap can be divided several times by vertically extending slots, so that the flap can adapt to the contour of the transported material on the conveyor belt.
