Definitions

  • the invention relates to a sweeping brush cover according to the preamble of claim 1. Furthermore, the invention relates to a sweeping brush assembly with such sweeping brush cover and a so-equipped sweeper. Furthermore, the invention relates to a method for covering a sweeping brush.
  • sweeping brushes In cleaning vehicles, especially in sweeper vehicles for snow removal, large, cylindrical or cylindrical sweeping brushes are used. These sweeping brushes with bristles of steel or plastic can be several meters long and are operated at considerable speeds and the appropriately equipped sweeping vehicles are used, for example, for clearing snow on airport runways or on roads. Such a vehicle is eg off EP-A-0 288 436 known and in FIG. 8 shown. Above the sweeping brush, a cover is provided as a rigid, curved shield. It is also known to form the cover of two rigid shield parts, which are pivotable to each other, or to provide a single, pivotable, rigid shield, which is to be adapted to the operating in the sweeping brush by wearing the bristles reducing brush diameter.
  • the cavity formed by pivoting rigid shield parts in various forms above the brush can fill with snow and it can form ice, which is disadvantageous.
  • By turning in while panning its shape-changing cavity is also the routing of the entrained by the brush snow different depending on the brush diameter.
  • the invention is based on the object to provide a sweeping brush cover which does not have these disadvantages.
  • the shield element is formed from a plastic, which results in a cover which is advantageous in terms of weight and can provide a smooth surface without high processing costs during manufacture, to which snow does not adhere.
  • a plastic which results in a cover which is advantageous in terms of weight and can provide a smooth surface without high processing costs during manufacture, to which snow does not adhere.
  • an ultra-high molecular weight polyethylene is used, if necessary with a wear-optimizing additive, in particular of glass particles.
  • the adjusting means on guides, in particular two coupled parallelogram guides, which adjust the front and the rear end of the shield element in the course of bending to adapt to the diameter of the sweeping brush so that in most or all bending situations, there is a cavity extending continuously rearward to the outlet above the sweeping brush.
  • Such adjustment means have the advantage that they require little installation space above the brush.
  • the adjusting means are further designed so that the outlet side, a rotation of the element takes place in order to better adapt to the sweeping brush shape.
  • the invention is further based on the object to provide a sweeping brush assembly and a sweeper, which do not have the disadvantages mentioned.
  • FIG. 8 shows a basically known Kehrblasmaschine 15, which is used in particular for removing snow from the surface 5 to be cleaned.
  • the sweeper for this purpose has a sweeping brush 10, which is arranged as a substantially cylindrical roller and is rotationally driven in the direction of the arrow shown.
  • the sweeping brush 10 may have a width of several meters and is provided with sweeping bristles of steel and / or plastic.
  • a rigid shield which prevents the sweeping brush mitgeschörderten snow that dissolves from the sweeping brush, to be thrown free upwards.
  • This and the other known shields have the disadvantages mentioned in the introduction.
  • FIG. 1 shows a state in which the sweeping brush is new or practically new and has the diameter D1.
  • FIG. 2 shows a practically completely worn sweeping brush, in which the diameter is only D2.
  • the sweeping brush cover in this case has a non-rigid, elastically bendable, or curved, plate-shaped shield element 2, which is bent to adapt to the substantially cylindrical shape of the sweeping brush roller.
  • the elastic plate-shaped element 2 covers the sweeping brush in its upper region and extends from the inlet side E to the outlet side A.
  • a wedge-shaped element 6 is provided on the inlet side, which, seen in the direction of rotation of the brush, before the element 2 comes to rest and thus forms the inlet E in this embodiment.
  • the elastically, and seen from the longitudinal axis L of the sweeping brush ago, convexly curved element 2 is held by adjusting means and is adjustable by this in its curvature or curvature.
  • the elastic element 2 may consist of a metal sheet, but is preferably formed of a plastic material. In this case, preferably an ultra-high molecular weight polyethylene is used, which for example has a molecular weight of> 5x10 6 g / mol. Such a material, the material TIVAR® ® is eg 1000 from Quadrant.
  • the curved plate-shaped element 2 can in the basic form of FIG. 1 be bent for the sweeping brush with the basic diameter D1, so that the element 2, the in FIG. 1 has shown basic form and this retains itself and starting from this until the further bent shape of FIG. 2 is deformed by the adjustment.
  • the element 2 can not be pre-bent and thus flat, so that the curved shape of FIG. 1 imposed by the adjustment and is maintained by this and the element 2 would spring back into its planar basic shape, if it were not held by the adjusting means in the curved shape.
  • the adjusting effect the further curvature to the maximum curved end position of the FIG. 2 ,
  • the adjusting means are shown schematically and have the means 3 and 4, which are each driven to pivot about axes 13 and 14, as this is indicated by the arrows a, or which are driven by means of shafts 13, 14 are pivotally driven accordingly.
  • the adjusting means 3, 4 longitudinally adjustable members, which are adjustable according to the arrows b in their length adjustable.
  • the adjusting means 3 engages the inlet-side wedge 6. This is just an example. If no wedge 6 is provided, the adjusting means acts essentially directly on the element 2. Such is shown for the adjusting means 4, which acts on the outlet side of the element 2 via a holder 7. This holder 7 may be attached to the element 2 in any manner.
  • FIG. 2 shows correspondingly reduced to its minimum usable diameter D2 sweeping brush. It can be seen that by pivoting the adjusting means 3 upwards and Longitudinal adjustment of the adjusting means 3, the element 2 on the inlet side gradually more and more to adapt to the decreasing diameter of the sweeping brush is bent. At the same time takes place with the adjusting means 4, which is pivoted downwards and also driven in its length, a bend of the element 2 within its elastic bending range for adjusting the outlet side of the element 2 to the decreasing sweeping brush diameter.
  • the bending is preferably carried out in such a way that the cavity between the sweeping brush circumference and the sweeping brush directed towards the inside of the curved element 3 from the inlet side to the outlet side is greater.
  • this is shown with the two distances d1 and d2, which show this preferred adjustment of the adjusting means and the sweeping brush cover both with a large sweeping brush diameter and with a low sweeping brush diameter. Since, however, by the adjusting means within the limits of the bending stress of the element 2 whose curvature is freely selectable, a different geometry of the cavity can be selected. For the discharge-side removal of the snow swept by the sweeping brush, however, the preferred embodiment is the most suitable.
  • FIGS. 3 to 6 show, again in side view, a preferred embodiment of the adjusting means for bending the element.
  • FIG. 7 shows the corresponding embodiment in a view from above of the sweeping brush 10 and the sweeping brush cover 1.
  • the longitudinal extent of the sweeping brush 10 in FIG. 7 clearly visible and it is shown that in each case left and right of the sweeping brush 10 and the element 2 are arranged adjusting means.
  • the FIGS. 3 and 4 show the adjusting completely or show the adjustment means for the inlet side and the outlet side.
  • FIGS. 3 to 7 the inlet-side adjusting means 3 'is formed by a first parallelogram and the outlet-side adjusting means 4' is formed by a second parallelogram.
  • the outlet-side adjusting means 4' is formed by a second parallelogram.
  • FIG. 7 shows a preferred embodiment, wherein in each case two parallelogram 4 'are combined with one drive 12 and accordingly also two parallelogram 3', which, however, in FIG. 7 are not designated.
  • a larger number of adjusting means could be provided, so in particular another pair of parallelogram arrangements, which eg in FIG. 7 centered would be.
  • the mentioned drive 12 which is formed in each case by a pneumatic cylinder or hydraulic cylinder or electric drive or a hand crank drive, engages on the one hand on a stationary, in particular fixed to the chassis of the sweeping brush assembly connectable or connected, support 11, which also provides axes of rotation for the Parallelogramman extract ,
  • the drive 12 is pivotally mounted about the axis 40 to the support 11.
  • the drive 12 is also pivotable about the axis 43 connected to the lower parallelogram 20 of the parallelogram 4 '. This has an upper parallelogram 21.
  • the upper lever 21 is rotatably connected to the support 11 via the axis 41, while the lower lever 20 is rotatably connected to this support 11 via the axis 42.
  • the upper parallelogram assembly 4 'for the outlet side of the element 2 is closed by the lever 22, which is connected by means of the axes 46 and 47 pivotally connected to the upper lever 21 and to the lower lever 20.
  • An extension of the lever 22 is pivotally attached to the bracket 7 via the axle 28, which is fixed to the element 2. This is so in FIG. 5 shown.
  • a preferred modification is shown in which the holder 7 is given an additional rotation about the axis of rotation 28 'in order to allow an even better adaptation of the outlet side of the element 2 by an additional bending of the outlet region of the element 2.
  • a lever 17 is provided with the axis of rotation 17 ', which causes via pins 18 and 19 and the lever 16, a corresponding rotation of the holder 7 from the Parallelogrammamba, as compared in the FIGS. 3 and 4 is easy to see.
  • a rotation could also be effected by a separate drive or another arrangement of the levers 16, 17.
  • FIGS. 3 and 4 show the upper parallelogram 4 'separately in the two extreme positions for the non-worn sweeping brush 10 and for the virtually completely worn sweeping brush.
  • FIG. 5 on the other hand, for better understanding, the parallelogram arrangement 4 'and the two sweeping brush diameters are shown in the same figure. Accordingly, two surfaces 5 are shown.
  • the parallelogram 4 is shown with solid lines for the large sweeping brush diameter and with broken lines for the small sweeping brush diameter. It can be seen how, by adjusting the parallelogram, the element 2 moves on the outlet side and thus is increasingly bent starting from the position with a large sweeping brush diameter, wherein in addition the outlet side is adapted to the decreasing sweeping brush diameter. In the FIGS. 3 and 4 can be seen how this is effected by the extension of the drive element 12.
  • FIGS. 3 and 4 and in particular for better illustration in the FIG. 6
  • the lower parallelogram 3 'can be seen which has a first lever 30 which is articulated via a pivot axis 31 on the fixed support 11 and is attached via a further pivot axis 32 to the element 2, which in the illustrated Example via the wedge 6, which is attached to the element 2.
  • the second lever 33 of the parallelogram 3 ' is articulated via the axis 34 pivotally mounted on the fixed support 11 and on the axis 35 in turn on the element 2 and in this embodiment on the wedge 6.
  • FIG. 6 clearly seen how the parallelogram 3 'moves the wedge 6 substantially parallel to the surface 5 and the element 2 increasingly convex bends with decreasing sweeping brush diameter and the inlet side of the change in size of the brush tracks.
  • FIGS. 3 and 4 it can be seen that the two parallelogram assemblies 3 'and 4' are drive-connected, so that the drive 12 actuates both parallelogram arrangements. In the example shown, this is done via a connecting member 45 which engages with one end on the lower lever 20 of the parallelogram 4 ', this in the example shown on the axis 43, and which is hinged at its other end to the lever 33, this over an axis 46th
  • the flexible element 2 is in the illustrated embodiments, a single and integrally formed element, which is preferred.
  • the element could, however, too be made of several parts, so in particular along the length of the sweeping brush 10 consist of several individual sections with their own adjusting means.
