Definitions

  • the present invention relates to a self-propelled soil compactor, as it can be used for example for compacting asphalt, gravel, soil or the like.
  • soil compactors generally have at least one compressor roller, with which they move over the substrate to be compacted and on the other hand cause compaction by loading on the one hand and the introduction of vibrations on the other hand.
  • At least one stripping device is provided, which is in operation with a surface of the compactor roller in contact.
  • a stripping device can be achieved on the one hand, that is applied to the surface of the compressor roll applied liquid, so for example water, in the width direction on the roll surface to prevent by the thus generated liquid film on the roll surface, the adhesion of the material to be compacted or at least to complicate. Further, by the standing in contact with the roller stripper thereon adhering materials can be detached.
  • JPH 068408 U discloses a self-propelled soil compactor according to the preamble of claim 1.
  • a scraper associated with a compacting roller can be pivoted from an operating pivoting position towards a non-operating pivoting position by acting on an actuating lever.
  • a locking arrangement comprises a pivotable with the scraper and a locking member providing locking pin.
  • a counter-ratchet-providing opening is arranged in a frame-fixed component. The locking member can be withdrawn against a biasing spring action and locked in such a retracted position. Arrives in the course of the pivotal movement of the scraper, the locking member in alignment with the frame-fixed counter-latching member, the locking of the locking member can be repealed and this occur in latching engagement with the counter-latching member.
  • a self-propelled soil compactor according to claim 1.
  • This comprises at least one compressor roller and in association with at least one compressor roller at least one stripping device with a pivotally supported on a support assembly and in an operating pivot position in contact with the associated roller scraper, an actuating lever for Swinging operation of the scraper and a latching arrangement for locking the scraper in at least one inoperative pivoting position out of contact with the associated compacting roller.
  • the actuating lever is connected in a mounting region with the scraper for common pivoting and has a loading area for initiating a pivoting actuating force.
  • the stripping device is provided on a soil compactor in association with a compressor roller
  • the embodiment may be advantageous as a handle, of course, the embodiment of an actuating lever both for foot control and is possible for manual operation.
  • the latching arrangement has a latching element and a counter-latching element which can be brought into latching engagement with the latching element to lock the stripper in the inoperative pivoting position.
  • the locking member between an active position and an inactive position is adjustable to increase the functionality, wherein in the active position, the locking member is in latching engagement with the counter-latching member or can be brought and in the inactive position is not in locking engagement with the counter-latching member or can be brought. If the locking member is in its active position, it can be ensured that the wiper is either held in its inoperative pivoting position or, when moving from the operational pivoting position to the inoperative pivoting position, this holding interaction is forcibly generated.
  • the latching element If the latching element is in its inactive position, then the latching effect can not be generated even when moving in the direction of the inoperative pivoting position, ie the latching arrangement does not lock the stripper in its inoperative pivoting position.
  • This inactive position of the locking member can be selected in particular when, for example, only for a short time, the scraper of the associated compressor roller, lifted, ie to be pivoted away, a lock in a Außer istenkgna, however, is not required or desired.
  • the counter-latching member has at least one engageable by the latching organ catch member stop, which may advantageously be provided that at least one locking organ stop is provided by a detent opening of the counter-latching member.
  • the counter-latching member is provided on the support assembly and the latching member is pivotable with the scraper.
  • the locking member may be provided on the actuating lever, so that when acting on the actuating lever for pivoting the scraper and the locking lever then provided on the locking member can be manipulated, for example, can be brought from its inactive position to its active position.

  • both the function of distributing a liquid film on the roller surface of a compressor roller, as well as the function of stripping impurities can be achieved even better that at least one compressor roller two strippers are assigned, preferably a scraper cooperates in a ground-level area with the compacting roller and a stripping device cooperates in a floor-remote area with the compacting roller.
  • the two stripping devices with respect to the axis of rotation of the compressor roller approximately diametrically opposite, so that they can fulfill their functionality at an angular distance of approximately 180 °, so evenly distributed over the circumference of the compressor roller.
  • Fig. 1 is a generally designated 10 soil compactor, also commonly referred to as a compactor roller shown.
  • the soil compactor 10 comprises a rear vehicle area 12, on which a drive unit (not shown), a driver's cab 14 and wheels 16 driven for propulsion by the drive unit are provided.
  • a front vehicle area 18 is pivotably connected to the rear vehicle area 12, wherein the direction of travel and thus also the working direction can be influenced by pivoting the front vehicle area 18 with respect to the rear vehicle area 12 about a substantially vertical pivot axis.
  • a compressor roller 20 is provided at the front vehicle area 18. This may be associated with a vibration or vibration drive, not shown, in order to put the compressor roller 20 into vibration during the advancing movement of the soil compactor 10 and thus to influence the compression behavior.
  • the compressor roller 20 comprises a jacket 22, which is generally also referred to as a smooth bandage and whose surface 24, which is exposed to the outside, is in contact with the substrate 26 to be compacted.
  • Fig. 1 recognizable structure of a self-propelled soil compactor 10 is only an example. This could be varied in various aspects.
  • a further driveable compressor roller 16 could be provided on the rear vehicle area 12.
  • two adjacent compressor rolls could be positioned at the front and / or rear of the vehicle.
  • a generally designated 28 stripping recognizable In association with the compacting roller 20 is in Fig. 1 a generally designated 28 stripping recognizable.
  • This scraper device 28 can be used, for example, to distribute liquid sprayed onto the surface 24, in order to make it difficult or prevent the adherence of the substrate material to be compacted.
  • This stripping device 28 can also be used to strip off the surface material 24 adhering to the surface 24 during the advancement of the soil compactor 10 from the surface 24.
  • a scraper 38 of the scraper device 28 is pivotably mounted about an approximately horizontal axis, for example, two pivot connection regions 34, 36. Die Abstreifer 34 , . Each of these pivot connection regions 34, 36 comprises a tab 40 on the wiper 38 and a tab 42 on the frame 30.
  • a pivot connection bolt 44 passes through the two tabs 40, 42 and thus binds the wiper 38 pivotally to the frame 30.
  • a leg spring 46 may be disposed surrounding the pivot pin 44 and supported with its legs with respect to the tabs 40, 42 and with respect to the stripper 38 and the frame 30, thus biasing the stripper 38 into an operative pivot position in which it contacts the surface 24 of the compressor roller 20 is.
  • the scraper 38 may be formed with a scraper blade 48 contacting the surface 24 in the operative pivoting position and a scraper bar 50 generally reinforcing the scraper 38, with which the scraper blade 48 may be fixedly connected by, for example, bolting.
  • a generally designated 52 and designed in the illustrated embodiment as a foot pedal operating lever is provided.
  • this is connected to the wiper 38.
  • a reinforcing plate 56 may be provided, for example, on the scraper bar 50, which extends between the swivel connection region 34 and this lateral edge region of the scraper 38 and thus can provide a stable connection of the actuating lever 52 to the scraper 38 against torsion.
  • the operating lever 52 provides a pedal surface 60 which may be formed with a slip-resistant configuration 62, such as a rib structure or the like, to prevent slippage of a shoe pressing on the loading area.
  • the scraper device 28 comprises a latching arrangement, generally designated 64.
  • a detent member 66 designed as a latching bolt is displaceably received in a direction of a bolt longitudinal axis and rotatably received about the bolt longitudinal axis in a guide sleeve 68 fixed to the actuating lever 52, for example by welding, screwing or the like.
  • the latching member 66 is biased by an unillustrated in the figures, biasing member 66 toward an active position in which a detent 70 of the locking member 66 can engage in a detent opening 72 of the frame 30 fixed counter-latching member 74.
  • a cam-like Abweisschräge 76 is provided, at which upon pivoting of the scraper 38 from the operating pivot position to the inoperative pivoting position, the detent end 70 of the locking member 66 comes to rest. Due to the action of the cam, the latching element 66 is displaced in its longitudinal direction counter to the preloading effect mentioned above, which results in Fig. 5 a displacement of the locking member 66 to the right means. This displacement continues with further pivoting until the locking end 70 is aligned with the example slot-like locking opening 72.
  • a tensile force can be applied to a provided on the locking member 66 operating portion or operating handle 78, which pulls the locking member 66 against the biasing action with its locking end 70 of the latching opening 72.
  • the scraper 32 due to the biasing action of the leg springs 46, automatically pivots back into its operating pivoting position. If the pulling force acting on the latching element 66 is then given up, it shifts back into its active position, in which the latching element 66 can again be brought into latching interaction with the counter-latching element 74 upon subsequent renewed loading of the actuating lever 52.
  • the latching member 66 is also rotatable in the guide sleeve 68 fixed to the actuating lever 52 about its longitudinal axis.
  • the guide sleeve 68 is then provided with an elliptically shaped cam surface 80, for example, by obliquely cutting off a tubular component in this example.
  • locking member 66 causes caused for example by applying a rotational force on the actuating portion 78 rotation of the locking member 66 that the actuating portion 78 moves along the cam surface 80 while the locking member 66 is moved from its active position towards an inactive position.
  • This rotating action on the locking member 66 can also be used to cancel the locking engagement in the locking opening 72, but then release the locking member 66 again, so that it returns to its biasing action returns to the active position.
  • the interpretation may be, for example, such that a rotation of the locking member 66, starting from its maximum to the counter-latching member 74 shifted positioning by 90 ° to such a displacement of the locking member 66 that it no longer engages the detent opening 72, the locking interaction with the counter-latching member 74 is thus repealed while still ensuring that in subsequent release of the latching member 66 this returns to its maximum on the counter-latching member 74 to be moved positioning.
  • the actuating portion 78 moving along the cam surface 80 can then be moved past a dead center of the cam surface 88 and into, for example, a slot provided in the guide sleeve 68 or a depression in the cam surface 88 engage.
  • the locking member 66 is then in its inactive position in which it is so far retracted and also held back that his locking interaction with the counter-latching member 74 is no longer possible.
  • This positioning of the locking member 66 can be selected when the production of a positive locking during pivoting of the scraper 38 from its Radioschwenk ein is not required or not desired.
  • the detent member 66 automatically returns to the active position. It may be advantageous if the cam surface 80 is formed symmetrically, so starting from the inactive position, a pulling or rotating the locking member 66 in any direction allows the return to the active position.
  • actuating lever 52 Due to the structural connection of the actuating lever 52 with the latching arrangement 64, a very easy handling of the scraper device 28 during pivoting or latching or latching release is enabled, so that, for example, the actuating lever 52 is acted upon by foot and the latching member 66 with one hand or one Foot is manipulated to cancel, for example, the latching engagement or return the latch member 66 in its active position or to move it towards its inactive position without an operator bending down, whereby an ergonomic advantageous operability is obtained.
  • the Fig. 2 shows that two such stripping devices 28 and 28 'can be provided in association with one and the same compressor roller.
  • the previously explained in detail and in the Fig. 3 to 6 shown in more detail stripping device 28 is provided in a ground-level area, for example, a height up to a maximum of 40 cm above the ground at the lower portion 32 of the frame 30, so that here an operation by foot is easily and ergonomically possible.
  • the second scraping device 28 ' is at an upper portion 82 of the frame 30 and one with respect to a rotational axis of the compacting roller 20 of the stripping device 28th Arranged approximately diametrically opposite positioning, so that the two stripping devices 28, 28 'can fulfill their functionality distributed over the circumference of the compressor roller 20 as possible.
  • the stripping device 28 ' Since the stripping device 28 'is positioned in a region further away from the ground, it is appropriate in this case to design an actuating lever assigned to this stripping device 28' as a handle, with which, for example, B. can be moved out of its Radioschwenkgna by pulling attack the scraper this scraper 28.
  • the structural design of the stripping device 28 ' in particular also with regard to the latching arrangement, can be designed as described above with respect to the stripping device 28.
  • the actuating levers associated therewith are preferably provided on the same side of a soil compactor. If the compactor with several compressor rollers, so for example a compressor roller, formed at the front of the vehicle and a compressor roller at the rear of the vehicle, and each of these compressor rollers associated with one or more stripping devices with corresponding operating levers, all these actuating lever are further preferably on the same side of the soil compactor provided, so that an operator can very quickly, for example, to carry out cleaning all levers can use to bring all scrapers in their out of order swing positions and lock in this.
  • the counter-latching element in association with such a stripping device, can be designed so that several out of operation pivoting positions can be maintained by latching by providing a plurality of latching openings. Further, it is possible to design the counter-latching member in such a way that the out-of-operation pivoting position in which the scraper pivots furthest away from the associated compressor roller is not the maximum achievable Außer jossschwenkgna corresponds.
  • the scraper in the reachable by latching out of operation swing position of the scraper have a distance of about 50 mm to the surface of the associated compressor roller, while a maximum pivoting up to a distance of, for example, 60 mm is possible. It is also self-evident that the scraper itself can be structurally executed in a different manner and can be pivotally supported on more than just two swivel connection areas on a body part of the soil compactor.
