Description

[Technical Field]

[0001] The invention relates to a road finishing machine according to claim 1. [Background technology]

[0002] In practice, road finishing machines are used to produce asphalt, including road pavements. During the laying of asphalt-bonded road construction materials, high processing temperatures can lead to the formation of asphalt-containing aerosols, which affect the air quality around the road finishing machine. Therefore, known road finishing machines use suction systems to suck out the aerosols and prevent the aerosol concentration in the air from reaching critical values.

[0003] In known suction systems, aerosols are typically sucked near the center of the machine, i.e., at the center of the exit of the scraper belt, which transports paving material from the road finisher's material bunker to its screed. At the exit of the scraper belt, the paving material is discharged from the end of the scraper belt into a lateral distribution area and distributed forward of the road finisher's screed by lateral distribution augers located there. However, during the lateral distribution of paving material to the outside of each screed, aerosols are formed even after the paving material leaves the area under the scraper belt laterally. However, aerosols formed along the outer sections of the screed are no longer adequately collected by conventional centrally located suction systems.

[0004] EP 0 843 044 A1 discloses a road finishing machine equipped with a ventilation system for suctioning aerosols, especially rising vapors, from the area above the lateral distribution system. The suction device used therein comprises a suction device component that covers the auger space at least to the top and optionally extends laterally to an extendable drawer component provided on the screed. A problem with this suction device is that the screed operator's view of the lateral material distribution area is very limited. Furthermore, assembling this suction device is cumbersome, especially when drawer components and / or lateral screed attachments for widening the paving width are used on the screed. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION It is an object of the present invention to provide a road finishing machine with a suction device that makes it possible to reduce the above-mentioned drawbacks associated with the prior art. [Means for solving the problem]

[0006] This object is achieved by a road finishing machine according to claim 1. Advantageous further developments of the invention are given by the technical features of the respective dependent claims.

[0007] The present invention relates to a road finishing machine including a screed for producing paving layers from paving material, in particular for producing paving layers from asphalt-bonded paving material. The road finishing machine according to the invention further includes a material bunker for receiving the paving material and a longitudinal conveying device configured to transport the paving material from the material bunker to the screed against (reverse) the direction of movement of the road finishing machine.

[0008] The road finisher according to the invention further comprises at least one transverse distribution auger configured to distribute transversely to the direction of movement the paving material transported to the screed by the longitudinal conveying device in front of the screed, the transverse distribution auger being mounted in front of the screed base of the screed in the direction of movement and preferably also mounted in a transverse distribution channel optionally arranged in front of the screed for the transverse distribution of the paving material, which is formed transversely to the direction of movement in front of the screed and at least in part (e.g. in multiple parts) by a channel plate supported on the chassis of the road finisher and by a press scraper mounted transversely to the screed base of the screed.

[0009] Furthermore, the road finisher according to the invention comprises at least one suction device on the inlet side, with at least one suction line formed therein, which is configured to suck aerosols formed during the lateral distribution of the paving material, in particular from the area along the lateral distribution channel, whereby the aerosols can in particular be sucked from the area outside the lateral distribution channel.

[0010] According to the present invention, the suction line is arranged at least partially (e.g., in multiple portions) in the channel plate of the lateral distribution channel, at least partially in the press scraper of the lateral distribution channel, at least partially in the front part of the screed base opposite the lateral distribution auger, and / or at least partially in the external control platform (external control table) of the screed.

[0011] In other words, in the present invention, the screed base, the channel plate, the press scraper and / or the external control platform of the screed are used as a base for attaching the intake line, which according to the present invention is therefore located directly in the screed part of the screed provided in any case and / or in a component of the lateral distribution channel optionally located in front of it.

[0012] Several implementation-related advantages result from the road finishing machine according to the invention, in particular from the suction system used therein according to the invention. On the one hand, the suction device can be installed without much effort, since its suction line is thereby attached directly to the screed structure. The invention also allows for a compact installation of the suction device on the road finishing machine. Furthermore, due to its reduced design, the suction device can be manufactured at an overall lower cost compared to conventional solutions. The suction device can also be flexibly adapted to the desired working width. Due to the suction line being located directly on the external control platform, in particular on the components used in its assembly, such as the side pusher, screed base, channel plate, and / or press scraper, it extends in close proximity to the paving material being transported laterally in front of the screed, making suction of aerosols along the suction line particularly effective.

[0013] Preferably, the suction line is at least partially (e.g., multiple portions) positioned on the side of the channel plate of the lateral distribution channel facing the lateral distribution auger, and / or at least partially positioned on the side of the press scraper of the lateral distribution channel facing the lateral distribution auger.

[0014] It is conceivable for the road finishing machine to include a first suction device comprising an intake line on the channel plate, press scraper and / or front part of the screed base, and / or a second suction device comprising an intake line on the external control platform, the two suction devices preferably being independently controllable.

[0015] Preferably, the suction line is a pipeline extending transversely to the direction of travel. It is contemplated that the pipeline has a round (e.g., circular) pipeline cross-section, although other cross-sectional shapes are also contemplated. The suction line is compactly formed in the form of a pipeline on the channel plate, press scraper, screed base, and / or external control platform, allowing the screed operator to easily view the lateral distribution of paving material across the set paving width, regardless of which side of the screed the screed operator is on. The inner diameter of the pipeline pipe can be only a few centimeters, e.g., approximately 5-10 centimeters.

[0016] According to one embodiment of the present invention, the air intake line is formed at least in part (e.g. in several parts) in the form of a rectangular pipe. This component shape allows the air intake line to be fixed in a particularly stable manner to the channel plate, the press scraper, the screed base and / or the external control site. Furthermore, an air intake line in the form of a rectangular pipe also provides a very robust structure for other shapes that support it, in particular for the construction of lateral distribution channels that are used as a foundation.

[0017] Regardless of the shape of the suction line itself, it can be positioned either forward or aft in the direction of travel relative to the side of the component supporting it. This means that the suction line can be formed as or integrated into the channel plate, prescraper, screed base, and / or external control platform, especially the side pusher support of the side pusher, as a visible line section on the outside, so that observers can only see the air inlets of these structures. Therefore, in the latter design, the suction line will run invisibly within the structure of the channel plate, prescraper, screed base, and / or side pusher support. This allows the suction line to be installed in a completely protected manner, while giving the screed operator an unrestricted view of the lateral material distribution.

[0018] Preferably, the intake line is made of a corrosion-resistant metal. In particular, the intake line is made of a light metal such as aluminum to facilitate the spreading of the screed. Since the intake line is made of the material of the supporting components used therein, i.e., the channel plate, the press scraper and / or the material of the front part of the screed base, the intake line is considered to be optically inconspicuous.

[0019] The air intake line is particularly formed in the form of an air intake rail, which can be integrated in a particularly compact way into the screed structure and the attachments formed thereon. The air intake rail is considered to extend along the entire width of the arranged lateral distribution channel, so that the aerosol can be completely sucked in over the entire width of the lateral distribution channel, especially outside the screed.

[0020] A particularly compact design can result from an air intake line that includes a wall at least partially (e.g., in multiple portions) formed as an integral part of the channel plate, the press scraper, the front part of the screed base, and / or a component of the external control platform, e.g., a side pusher support. According to this variant, the air intake line can be formed on the respective support side of the channel plate, the press scraper, the component of the external control platform, and / or the screed base, and can be forward or rearward in the direction of movement in an integrated manner. This can further improve the compact design of the air intake line. In the external control platform, the air intake line can be formed as part of the side pusher support, in particular integrated therein.

[0021] Preferably, the suction line is formed at least partially (e.g., multiple portions) along the upper edge of the channel plate, along the upper edge of the prescraper, and / or along the upper edge of the side pusher support of the external control platform. The suction line thereby extends directly along the upper boundary (upper edge) of the lateral distribution channel, so that aerosols or vapors formed therein can be better sucked directly at the location where they are generated. Furthermore, the placement of the suction line at the respective upper edges of the channel plate and / or prescraper can be a useful orientation aid for assembling the lateral distribution channel. The suction line can also be formed along the upper edge of the support component, in the front part in the direction of movement (this means as an attachment formed thereon), or integrated therein (this means the internal structure of the support component).

[0022] In particular, the suction lines formed in the front part of the screed base, the external control platform, the channel plate, and / or the press scraper are dimensioned in such a way that, when viewed from above, the lateral distribution channels remain essentially uncovered, meaning that the dimensions of the suction lines in the direction of travel are essentially smaller than the lateral distribution channels, so that the operator can fully observe the flow of material being conveyed laterally in the lateral distribution channels during the paving operation of the road finisher.

[0023] Preferably, the intake line forms an exhaust guide for the aspirated aerosol arranged transversely to the direction of movement along the transverse distribution channel. The exhaust guide can extend to the outside of the screed and / or to the center of the screed. Along the exhaust guide, the intake line can have multiple inlets, so that the exhaust flow conveyed in the exhaust guide is formed from multiple intake flows.

[0024] The suction line advantageously comprises a plurality of interconnectable line sections, preferably arranged in series transverse to the direction of movement, the joining ends of which are formed in the region of the separation points of adjacently mounted channel plates and / or adjacently mounted press scrapers. Preferably, the channel plates and / or press scrapers including the suction line formed therein can be assembled without tools, e.g. without further assistance, which facilitates assembly at the construction site.

[0025] It is conceivable that the suction device is available as a retrofit kit, at least the individual components of which are arranged on a road finishing machine according to the invention.

[0026] Adjacent channel plates and / or prescrapers can be assembled together by the connecting ends of the suction lines. In the case of assembling the channel plates and / or prescrapers together, in this variant the connecting ends of the suction lines are present as a fastening means, which makes the assembly even easier for the operator. It is considered that the connecting ends of the suction lines of adjacent channel plates and / or prescrapers can be inserted into each other in part (e.g., multiple parts), thereby forming an overlap between the connecting ends.

[0027] According to a variant, the channel plate and / or the prescraper can be automatically moved transversely to the direction of movement, taking into account the set paving width. The suction lines attached thereto can in particular be made telescopic, so that they can be automatically adapted depending on the degree of extension (expansion) of the lateral distribution channel.

[0028] Preferably, the air intake line comprises a plurality of passages as a plurality of air intakes. The plurality of air intakes may be formed at least in part (e.g. in sections) on the outside of the screed along the air intake line. The passages may in particular take the form of slots. Along the air intake line, a plurality of parallel slots may be grouped at least in part (e.g. in sections) or may be formed consecutively.

[0029] According to one embodiment, the intake line includes at least one closing mechanism for opening and closing at least one of the intake ports formed therein, wherein the closing mechanism sets the adjacent intake port open in order to selectively suck aerosol in the area of ​​the external control platform of the screed, while other intake ports of the intake line located further in the center of the screed structure are selectively closed by the closing mechanism, thereby forming a higher suction effect in the area of ​​the external control platform.

[0030] According to a variant of the invention, the plurality of intake openings are formed on different sides of the intake line: it is conceivable that the plurality of intake openings are formed in the intake line along the side facing the lateral distribution auger in the direction of movement, along the side directed downwards towards the subsoil and / or along the side directed upwards.

[0031] Advantageously, the suction device comprises at least one fan connected to the suction line, for example located in the area of ​​the external control platform of the screed, in particular in the side pusher formed there for setting the paving width. Preferably, the fan power can be set directly on the external control platform by the screed operator, for example by means of a control device attached there. Thus, the screed operator can adjust the fan power himself depending on the aerosol generation situation during paving work.

[0032] The suction device may comprise at least one fan located in the area of ​​the chassis of the road finisher for sucking the aerosol through suction lines formed in the front part of the screed base, and / or at least one further separate fan for sucking the aerosol through suction lines formed in the channel plate, the press scraper and / or the external control platform. In particular, the latter part of the suction device may be provided to the customer as a retrofit kit for large screed widths. This also allows the fan power to be better divided over the entire working width, thereby allowing the aerosol to be sucked in more effectively. The fan described in the second option may be directly attached (integrated) to the external control platform.

[0033] Preferably, the suction device comprises, on the outlet side, at least one exhaust line fixed to the roof structure of the external control platform of the screed for discharging the sucked aerosol, whereby the structure of the suction device can be designed essentially in the external area of ​​the screed, and therefore exhaust guides installed on the chassis of the road finisher and on the roof structure of the driver control platform can optionally be eliminated.

[0034] According to one embodiment, the suction device includes at least one activated carbon filter unit, which allows for the purification of the aspirated air containing aerosols, thereby further improving the quality of the working conditions for the operator of the road finishing machine. The activated carbon filter unit can be formed on the external control platform, so that the air discharged there from the exhaust line is free of aerosols.

[0035] The intake line of the channel plate located closest to the road finisher chassis may be configured for coupling with a vent line formed in the road finisher chassis, thereby allowing the intake line to be connected to a suction system installed on the road finisher chassis.

[0036] Preferably, the suction device includes a spray device configured to spray a fluid (e.g., water vapor) onto the lateral distribution channel and into the aerosol formed therein to reduce the concentration of the aerosol. The spray device may include at least one nozzle disposed directly in the intake line.

[0037] According to a variant of the invention, the suction device includes at least one sensor unit, based on which measurement results a dynamic fan speed adaptation can be performed. The sensor unit can include a sensor configured to detect the aerosol content of its surrounding area, which can be kept continuously available as an actual value for the control loop for performing the dynamic fan speed adaptation. The dynamic fan speed control can respond in particular to the detected temperature of the paving material.

[0038] The invention will now be explained in more detail with reference to exemplary embodiments according to the following figures. [Brief explanation of the drawings]

[0039] [Figure 1]1 shows a road finishing machine for producing a paving layer. [Figure 2] FIG. 1 shows a perspective view of a road finishing machine with a screed provided as an extendable screed. [Figure 3] FIG. 1 shows a schematic plan view of an expandable screed for a road finishing machine. [Figure 4] FIG. 4 shows the extendable screed of FIG. 3 with laterally extended drawer parts. [Figure 5] 1 shows a screed with extended drawer sections and attachments mounted laterally thereon to create the desired working width. [Figure 6] 1 shows a schematic diagram of the external control platform of the screed. [Figure 7] 10 shows a diagrammatically represented positioning variant of the intake line on its supporting component; DETAILED DESCRIPTION OF THE INVENTION

[0040] In the figures, identical components are always given identical reference numbers.

[0041] Figure 1 shows a road finisher 1 for creating a paving layer 2 on a subsoil 3. The road finisher 1 comprises a material bunker 4 in front in the direction of travel R, from which the paving material 6 received is transported, against the direction of travel R of the road finisher 1, to a screed 7 of the road finisher 1 by means of a longitudinal conveying device 5. The longitudinal conveying device 5 is arranged in a chassis 8 of the road finisher 1 and comprises a scraper belt 9, which is shown in Figure 3.

[0042] From the scraper belts 9 of the longitudinal conveying device 5, the paving material 6 is transferred to a lateral distribution auger 10 arranged in front of the screed 7. The lateral distribution auger 10 is configured to distribute the paving material 6 in front of the screed 7.

[0043] FIG. 2 shows a perspective view of the road finishing machine 1. The screed 7 includes a screed base 11 and laterally extendable pull-out parts 12 for setting the desired working width B of the paving layer 2 to be produced. The pull-out part 12 on the left side shown in FIG. 2 has a side pusher 13 for setting the working width B of the newly laid paving layer 2. An external control platform 14 is arranged on the side pusher 13, which includes a control device 15 for the screed operator. The side pusher 13 includes a side pusher support 40 that can be used to configure the external control platform 14. From the external control platform 14, the screed operator can control and / or monitor the operation of the screed 7. It is particularly convenient for the screed operator to monitor the lateral distribution of the paving material 6 ahead of the screed 7, i.e., ahead of the pull-out part 12.

[0044] Figure 3 shows a schematic plan view of the screed 7 of the road finisher 1. The paving material 6 discharged by the scraper belt 9 in front of the screed base 11 of the screed 7 is distributed along the front part 16 of the screed base 11 by lateral distribution augers 10. The rear wall 22 of the chassis 8 of the road finisher 1, together with the front part 16 of the screed base 11, forms a lateral distribution channel 17 for the lateral distribution augers 10. This lateral distribution channel 17 can be further extended laterally to accommodate the expansion of the screed 7. This is shown in Figures 4 and 5.

[0045] 3 further shows that an air intake line 18a is formed in the front portion 16 of the screed base 11. The air intake line 18a includes a plurality of air intake openings 19 configured to suck in aerosols formed in the lateral distribution channels 17 during the paving operation.

[0046] The suction line 18a is configured in the form of a suction rail directly on the screed base 11 in Figure 3. It is therefore of a particularly compact design and allows the screed operator unrestricted visibility into the lateral distribution channels 17.

[0047] The suction line 18a may be configured as the suction end of a suction device 20 mounted on the chassis 8 of the road finishing machine 1. The suction line 18a may be connected to a fan 23, for example, via an exhaust guide 21. The exhaust guide 21 may also have a different extension, which may extend, for example, beyond the central auger suspension 24 to the fan 23.

[0048] 3 shows diagrammatically a spraying device 37 with a nozzle 38 for spraying the aerosol formulation in the lateral distribution channel 17. The spraying device 37 may be configured to generate water vapor.

[0049] Figure 4 shows the screed 7 in a schematic plan view with an extended pull-out element 12. By widening the screed 7 in this way, a larger working width B for the newly produced paving layer 2 can be created. Figure 4 also shows that the lateral distribution channel 17 is extended laterally beyond the screed base 11. The paving material 6 discharged by the scraper belt 9 can be transported along the widened lateral distribution channel 17 to the outside of the pull-out element 12. The lateral distribution auger 10, located within the lateral distribution channel 17 in Figure 4, is also extended.

[0050] The lateral distribution channel 17 arranged in front of the screed 7 is formed in its outer region transversely to the direction of movement R by a channel plate 25 supported on the chassis 8 of the road finisher 1 and by a pre-scraper 26 mounted laterally on the screed base 11. Depending on the set working width B, the channel plate 25 and the pre-scraper 26 can be extended further laterally in order to lengthen the lateral distribution channel 17. The same applies analogously to the lateral distribution auger 10.

[0051] Furthermore, Figure 4 shows that the suction line 18a formed in the front part 16 of the screed base 11 is extended by further suction lines 18b, 18c to suck aerosol from the lateral distribution channels 17. Thereby, the suction lines 18a, 18b, 18c are formed, according to Figure 4, at the side 27 of the channel plate 25 facing the lateral distribution auger 10, at the side 28 of the press scraper 26 facing the lateral distribution auger 10 and along the lateral distribution channels 17 in the front part 16 of the screed base 11.

[0052] The integral part of the channel plate 25 and the press scraper 26 (especially the intake lines 18b, 18c) allows the screed operator an unobstructed view of the lateral distribution channels 17.

[0053] Figure 5 shows a screed 7 with an extended pull-out part 12 and an attachment 29 fixed thereto transversely in order to generate a very large working width B for the paving layer 2. Figure 5 shows that lateral distribution channels 17 are formed along the screed base 11, the pull-out part 12 and along the attachment 29 fixed thereto transversely to the direction of movement R. Corresponding to the working width B, further channel plates 25 and press scrapers 26 are attached to further extend the lateral distribution channels 17.

[0054] 5 further shows that the intake lines 18b, 18c formed in the channel plate 25 and the prescraper 26 are extended to draw aerosol along the full extent of the lateral distribution channel 17. At the separation point 30a of the channel plate 25 and at the separation point 30b of the prescraper 26, the combined ends 31 of the intake lines 18b, 18c are connected to each other.

[0055] 3-5 show an intake line 18d disposed on the side pusher 13 of the external control platform 14. The intake line 18d may be configured as part of a suction device provided separately for the external control platform 14.

[0056] FIG. 6 shows, in a schematic view, the external control platform 14 of FIG. 2 with a roof structure 32 for the screed operator P. The external control platform 14 shows the screed operator P standing on a gangway 33 extending behind the screed 7 above the paving layer 2. The gangway 33 is also shown in FIG. 1. A fan 34 is provided on the side pusher 13. The fan 34 can be connected to the intake lines 18b, 18c, and 18d to suck aerosols from the lateral distribution channels 17. FIG. 6 further shows that an exhaust line 35, represented diagrammatically as a dashed line in FIG. 6, discharges the sucked aerosols from the fan 34 above the roof structure 32. FIG. 6 also shows an activated carbon filter unit 36 ​​for purifying the aerosols sucked from the lateral distribution channels 17.

[0057] The suction lines 18a, 18b, 18c, 18d, which are installed directly and integrally with the side pusher 13, screed base 11, channel plate 25 and / or press scraper 26 of the external control platform 14, form an advantageous inlet geometry for the suction device 20 in the road finisher 1. In particular, due to its reduced, compact structure with respect to the existing structure, the screed operator has a full view of the lateral distribution channels 17, regardless of how far they extend in front of the screed 7. The integrated design of the suction lines 18a, 18b, 18c, 18d reduces the manufacturing and assembly effort in the road finisher 1 as a whole.

[0058] FIG. 7 shows schematically that the intake lines 18a, 18b, 18c, 18d can be formed as visible attachments at the front, i.e. to the respective support components (i.e. the channel plate, press scraper, screed base 11 and / or side pusher support 40) in the assembled state according to the left representation of FIG. 7, or can be formed so as to be integrated into the structure of the support components according to the right representation of FIG. 7.

[0059] 7, the intake lines 18a, 18b, 18c, 18d are arranged at the level of the upper edge 28 of the channel plate 25 and the prescraper 26. The intake lines 18a, 18b, 18c, 18d therefore together form a frame that essentially surrounds the lateral distribution channel 17 for aspirating the aerosol formed in the lateral distribution channel 17. The arrows pointing in the direction of the intake lines 18a, 18b, 18c, 18d in FIG. 7 indicate from which side aerosol can be aspirated.
