Definitions

  • the invention relates to a device for cleaning the bandage of a roller for compacting soil from adhering contaminants and for sprinkling the bandage with water, this device being provided in a known manner with a stripping device which is essentially perpendicular to the direction of rotation of the bandage over the area to be cleaned extends from this and is fixed in a fixed position with respect to the bandage on the drum support, and with a nozzle device which is fixed in a fixed position with respect to the bandage on the drum support and with nozzles arranged at a mutual spacing approximately parallel to the stripping device for spraying water in the direction of the drum behind the stripper is provided on the bandage.
  • the stripping device and the nozzle device are provided as separate components, each of which must be attached to the drum support individually.
  • the object of the invention is to provide a device according to the introductory part of claim 1, which is improved both in terms of its structural design and in terms of its mounting on the drum support compared to the known devices in such a way that it has a lower manufacturing and assembly effort required.
  • the above object is achieved in that the scraper device and the nozzle device are combined to form a structural unit and these consist of a channel-like scraper holder which extends continuously over the width of the drum area to be cleaned, and of a scraper arranged in the scraper holder which Length of the scraper holder protrudes therefrom to form a bandage, a cavity, which is sealed against the scraper holder and extends over a substantial part of its length, into which a water supply line opens and from which the nozzles pass through the wall of the scraper holder branch off.
  • the device according to the invention consists of only a few components, each of a simple shape, which can be easily connected to one another to form the desired structural unit, and because all its parts are combined into a single structural unit, it is also very easy to mount on the drum support.
  • Fig. 2 seen the device in front view for the viewer of Fig. 1 from the left, the connecting piece between the device and the drum support is not shown for the sake of clarity, and
  • FIG. 3 shows the cross section through the device in section along the section line III-III in FIG. 2.
  • the device 1 shown in the drawing is used to clean a bandage 2 of a roller, which is only schematically indicated in FIG. 1, for soil compaction of adhering contaminants and for sprinkling the bandage 2 with water.
  • the device 1 is fastened by means of a connecting element 3 (not shown in FIGS. 2 and 3) for the sake of clarity, in the inclined position shown in FIG. 1 with respect to the bandage 2, on the bandage carrier 4, which is also only schematically indicated in FIG. 1.
  • the device 1 has a stripping device and a nozzle device, which are combined to form a structural unit.
  • This assembly consists of a trough-like scraper holder 5 formed from two parts 5a and 5b, which extends continuously over the width of the area of the bandage 2 to be cleaned, and a scraper 6 made of elastic plastic and arranged in the scraper holder 5, the parallel broad sides 6a , 6b and, with its end regions located on the left and right for the observer of FIG. 2, fills the cross section of the wiper holder 5 essentially in a liquid-tight manner.
  • the material of the wiper is preferably polyurethane.
  • the stripper 6 forms a cavity 10 which is sealed against the stripper holder 5 and extends over a substantial part of the length of the stripper holder 5, into which a water inflow line 11 passes through the wall of the stripper holder part 5a and out of it Branch nozzles 12 through the wall of the scraper holder part 5b.
  • the scraper 6 extends substantially perpendicular to the direction of rotation of the bandage 2 parallel to its surface over the area to be cleaned, and the nozzles 12 arranged at a mutual distance approximately parallel to the scraper 6 are arranged so that the water emerging from them in the direction of the bandage behind the Scraper 6 reaches bandage 2.
  • the two parts 5a, 5b forming the scraper holder are each bent at right angles along their longitudinal edges located at the top in the use position to the other parts 5a and 5b, the bent leg 5c of the part 5a facing the scraper 6 being essentially the thickness of the scraper 6 has the corresponding width.
  • the two parts 5a, 5b of the scraper holder are stiffened at the lower end by these legs 5c bent at right angles and by a further angled wall part 5d, so that the scraper 6 is securely held in the desired oblique position shown in FIG. 1 with respect to the bandage 2 is.
  • the part 5b located on the right for the viewer of FIG. 3 and at the back for the viewer of FIG. 2 runs at its lower end facing the bandage 2 into an angle over the wiper holder part 5a
  • Length distributed tines 5e, through openings 13 in the wiper 6 and through the latter having a smaller cross section openings 14th pass through in part 5a of the scraper holder 5.
  • the prongs 5e hold the stripper 6 immovably in the stripper holder 5 and at the same time secure the desired predetermined mutual position of the stripper parts 5a, 5b with respect to one another.
  • connection of the two parts 5a, 5b of the wiper holder 5 and the wiper 6 by means of the screw bolts 7a and nuts 7b brings about a secure releasable bracing of the wiper holder 5 against the wiper 6, so that no water from the cavity 10 along the broad sides 6a, 6b between the parts 5a and 5b on the one hand and the scraper 6 on the other hand can flow out.
  • the scraper 6 is preferably set against the drum 2 at an acute angle counter to the running direction.
  • a second device 1 is located at the opposite angle of attack on the other side of the upper apex of the bandage 2 and takes over the stripping function in the opposite direction of travel of the bandage 2.
