Definitions

  • the invention relates to a road milling machine according to the preamble of claim 1.
  • Known road milling machines generally have a machine frame and at least three driving devices, at least two driving devices being driven and at least one driving device being steerable. Furthermore, a road milling machine has at least one milling drum for processing the floor covering.
  • a suction device can also be provided for suctioning off air contaminated with dusts and vapors.
  • Milling off the floor surface creates dust and vapors that worsen the working conditions for the machine operator in the driver's cab and the other operating personnel around the milling machine and, under certain circumstances, impede the view of the traffic that may be passing by.
  • a suction device for a milling machine which is connected to a first channel section assigned to the transport devices and which extracts contaminated air essentially in the material transport direction in the first channel section during milling.
  • the U.S. 6,733,086 discloses a road milling machine with an extraction device for extracting air polluted with dusts and vapors.
  • the suction device has several lines. A first line connects a suction nozzle and the inlet of a material collector and a second line connects the air outlet of the material collector and the air inlet of a pump.
  • the prior art to date often has the disadvantage that a fan of the suction device is located in the dirt area, that is to say that the air contaminated with dusts and vapors flows through the fan.
  • the invention is based on the object of creating a road milling machine in which the dusts and vapors produced during the milling process can be effectively extracted without contaminating the fan of the extraction device.
  • the invention advantageously provides that at least one first exhaust pipe has at least one first pipe section with a first cross section and at least one second pipe section with a second cross section, the second cross section being smaller than the first cross section, with an intake duct having an inlet opening and a Having the outlet opening, the outlet opening opening into the exhaust air pipe in the region of the second pipe section, wherein the air contaminated with dusts and vapors can be sucked in at the inlet opening.
  • the present invention has the advantage that the Venturi effect is used in order to be able to extract the air contaminated with dusts and vapors particularly effectively.
  • the first pipe section lies upstream of the second pipe section in the direction of flow.
  • In flow direction means the direction in which the air flows through the suction device, in particular through the exhaust air pipe.
  • the suction device also has a fan which is connected to the first pipe section, so that air can be blown into the suction pipe by the fan.
  • the second pipe section lies behind the first pipe section in the direction of flow.
  • In the direction of flow also means in the direction in which the air is blown by the fan.
  • the present invention has the advantage that the fan is arranged in such a way that it is arranged on the clean side, i.e. the air contaminated with vapors and dusts does not flow through the fan.
  • a fan is understood to mean a driven turbo machine which preferably delivers air by means of an impeller operated in a housing and thereby preferably achieves a pressure ratio between 1 and 1.3 between the suction and pressure sides. This must be distinguished from flow machines with a pressure ratio greater than 1.3, which are compressors or compressors.
  • a fan can also be referred to as a blower or fan. The fan can be of the radial or axial fan type.
  • the exhaust air pipe can be designed in one or more pieces.
  • the individual parts can be connected to one another in a fixed or detachable manner.
  • the exhaust pipe can extend at least in the area of the first pipe section along a first longitudinal axis, the first longitudinal axis being arranged such that it runs essentially perpendicular to the floor covering, preferably at an angle between 70 and 90 ° to the floor covering.
  • the exhaust air pipe can extend at least in the region of the second pipe section along a second longitudinal axis, the second longitudinal axis preferably running parallel to the first longitudinal axis.
  • the second longitudinal axis can thus also be arranged in such a way that it runs essentially perpendicular to the floor covering, preferably at an angle between 70 and 90 ° to the floor covering. If the first and the second pipe section are arranged concentrically to one another, the first and the second longitudinal axis form a common longitudinal axis.
  • the arrangement of the first and / or second longitudinal axis essentially perpendicular to the floor covering has the advantage that coarse dirt particles in the polluted air, which are too heavy to be transported by the air, fall to the ground due to gravity and in this case along the first and / or second longitudinal axis of the exhaust pipe fall down in the direction of the floor covering.
  • the fan can be arranged in such a way that the air from the fan enters the exhaust air pipe essentially perpendicular to the first and / or second longitudinal axis of the exhaust air pipe.
  • the intake duct can open into the exhaust air pipe essentially perpendicularly relative to the first and / or second longitudinal axis of the exhaust air pipe.
  • the intake duct can protrude into the exhaust pipe. This has the advantage that the flow velocity at the outlet opening of the exhaust air duct is particularly high and the air contaminated with dusts and vapors is carried along particularly effectively.
  • the exhaust pipe can have a first opening and a second opening, the second opening being arranged above the first opening and the contaminated air being able to exit from the second opening.
  • the first opening of the exhaust air pipe can be arranged on a side facing the floor covering.
  • a collecting container can be arranged at the first opening of the exhaust air pipe.
  • the collecting container can catch the particularly coarse-grained protection that falls towards the floor covering.
  • the fan can be arranged below the intake duct and, relative to the first and / or second longitudinal axis of the exhaust air pipe, laterally next to the exhaust air pipe.
  • the outlet opening of the intake duct can be above the area in which the air blown by the fan is introduced into the exhaust air pipe.
  • the present invention has the advantage that the fan is arranged in such a way that the coarse dirt particles do not fall onto the fan, but rather fall past it.
  • a driver's cab can be provided, the second opening of the exhaust air pipe being arranged above the driver's cab.
  • the exhaust air pipe can have a third pipe section which is arranged downstream of the second pipe section in the flow direction, the third pipe section having a third cross section which is larger than the second cross section of the second pipe section.
  • a housing in particular a milling drum housing or milling drum box, can be arranged around the milling drum, an opening into which the intake duct opens and preferably the opening can form the inlet opening of the intake duct can be arranged on one side, especially on the rear side in the direction of travel.
  • the road milling machine can be a small milling machine, the small milling machine having at least two rear running gears and the milling drum being arranged between the rear running gears.
  • the suction device can be dismantled and devices can be provided to which a conveyor belt can be attached so that a conveyor belt can be connected instead of the suction device.
  • the suction device is thus provided in particular when no conveyor belt is provided on the road milling machine.
  • the exhaust air pipe can have a fourth pipe section which is arranged above the first and second pipe sections, the fourth pipe section being designed as a flexible hose which is expandable in length.
  • Fig. 1 showed a road milling machine 1 for processing the floor covering 4.
  • the road milling machine 1 has a machine frame 6 and at least three driving devices 2, 3. At least two driving devices 3 can be driven and at least one driving device 2 can be steered.
  • the road milling machine can, however, also have four driving devices, all of which can also be driven.
  • the road milling machine is a small milling machine in which the milling drum 11, shown only in dashed lines, is arranged between the rear travel devices 3.
  • the driving devices 2, 3 can be wheels or crawler drives. In the illustrated embodiment, the driving devices are wheels.
  • the road milling machine has a driver's cab 8 and a roof 62 above the driver's cab 8. The roof 62 can be height-adjustable with respect to the driver's cab.
  • the rear driving devices 3 can be height-adjustable in relation to the machine frame 6.
  • lifting columns are provided for the rear driving devices, with the aid of which the machine frame 6 can be adjusted in height.
  • the milling drum 11 mounted on the machine frame 6 can also be adjusted in height.
  • One of the two rear trolleys 3 can be of one in the Fig. 1
  • the outer end position shown can be pivoted inward into a recess 7 of the machine frame 6, so that the outer edge of the pivoted-in driving device 3 is approximately flush with the side of the road milling machine 1.
  • the milling drum can be arranged on the side on which one of the rear driving device 3 is pivoted so that it extends to the side of the machine frame 6 and is preferably flush with the side of the road milling machine 1, thus enabling milling close to the edge.
  • This side on which milling close to the edge is possible is called the zero side.
  • Fig. 1 the suction device 12 is already shown. In the illustrated embodiment, no transport device is provided.
  • the milling drum 11 is arranged in a housing 10, in particular a milling drum box.
  • An opening 15 is provided on the rear side 14 in the direction of travel. Behind the opening 15 is the inlet opening 30 ( Fig. 3 ) of the intake port 18 ( Fig. 3 ) arranged.
  • the suction device 12 is more precisely in the Figs. 2 , 3rd and 4th shown.
  • the suction device 12 has at least one exhaust air pipe 13.
  • the first exhaust pipe 13 has at least one first pipe section 24 and at least one second pipe section 20.
  • the first pipe section 24 has at least a first cross section 26 and the second pipe section 20 has at least a second cross section 22.
  • the second cross section 22 is smaller than the first cross section 26.
  • the suction channel 18 has an inlet opening 30 and an outlet opening 28. The outlet opening 28 opens into the second pipe section 22 of the suction pipe 13.
  • a fan 16 is arranged below the intake duct 18. This fan 16 is preferably arranged laterally next to the exhaust air pipe 13. Below and above should be used in the following in such a way that this is to be understood in relation to the floor covering. Above means further away from the flooring and below means closer to the flooring.
  • the exhaust air pipe shown has a first longitudinal axis 46 at least in the first pipe section 24 and a second longitudinal axis 47 in the second pipe section 20.
  • the first and second longitudinal axes 46, 47 run essentially perpendicular to the floor covering.
  • the first and / or the second longitudinal axis 46, 47 preferably have an angle ⁇ between 70 and 90 ° to the floor covering 4.
  • the exhaust air pipe 13 may have a fourth pipe section 60, which is arranged above the first and second pipe sections 24, 20, the fourth Pipe section 60 is designed as a flexible hose which is expandable in length.
  • the flexible hose is designed in the shape of an accordion and can therefore expand in its length.
  • the suction channel 18 preferably protrudes into the exhaust air pipe 13 by the amount X.
  • the flow velocity in the exhaust air pipe in the area of the outlet opening 28 of the suction channel 18 is particularly high and the contaminated air can be removed particularly well.
  • the exhaust pipe 13 can be formed in one piece or in several pieces. In the present case, the exhaust pipe 13 is composed of several pieces.
  • the exhaust pipe does not have to run in a straight line either.
  • the exhaust pipe has a first and a second opening, the second opening 34 being arranged above the first opening 36.
  • the first opening 36 is arranged on the side facing the floor covering. The polluted air can exit the second opening 34.
  • a collecting container 38 can be provided at the first opening 36 of the exhaust air pipe 13.
  • the collecting container 38 is open at the bottom. However, this can easily be closed with a lid.
  • the collecting container 38 can also be made of a flexible material and can be turned over at the lower end and closed in this way.
  • the exhaust pipe 13 can also have a third pipe section 50, which has a third cross section, the third cross section 52 being larger than the second cross section 22 of the second pipe section 20.
  • the cross section of the exhaust pipe is thus larger again in the flow direction behind the entry of the polluted air . This has a particularly positive effect on the extraction of the polluted air.
  • the suction channel 18 If dust arises in the milling drum box, it can enter the suction channel 18 through the opening 15 and the inlet opening 30.
  • the fan 16 blows air into the exhaust air pipe 13. Because the air is blown into the first pipe section 24 and the second pipe section 20 has a smaller cross section 22, the flow velocity in the second pipe section 20 is higher. In this way, a negative pressure arises at the outlet opening 28 of the intake channel 18. The contaminated air is therefore sucked in through the intake channel 18.
  • the air blown into the exhaust air pipe 13 by the fan 16 therefore takes the polluted air with it and leads it to the second opening 34, where the polluted air can exit. If there is coarse-grained dirt in the polluted air that cannot be carried by the air, it falls through the exhaust pipe 13 down into the collecting container 38. Since the fan 16 next to the exhaust pipe, ie in relation to the longitudinal axis 46 next to the exhaust pipe and is arranged below the suction channel 18, even the coarse-grained dirt does not fall onto the fan 16. The contaminated air 18 does not have to flow through the fan 16 either. The fan is therefore arranged on the clean side. In this way, the fan 16 has a longer service life and does not have to be cleaned as frequently.
  • the "Venturi effect" can be used particularly well and the suction is particularly effective.
