Definitions

  • the present invention concerns dish brushes with a raised contour brim under angle ⁇ noise reducing first and/or second sweeping elements which dish brush is mounted under a sweeping machine for removing dirt and/or weeds from the surface of all kind of pavements such as cobblestones, concrete paving stones or tiles (i.e. all pavements with joints), wherein said first sweeping elements are built up of bending strength threads or as small strips of all kinds of materials to remove dirt or litter from said pavement and said second sweeping elements are built-up from steel cable plugs, wherein said first and second sweeping elements are mostly covered with a plastic material.
  • Mentioned patent application concerns a dish brush for mounting at a rotating vertical driving axle under a conventional sweeping machine for brushing, sweeping or cleaning paved surfaces, wherein the dish brush is built-up of a circular plate with a raised contour edge or rim, wherein at this bottom side sweeping elements are fixed at mutual equally tangential distances.
  • First sweeping elements are flat sweeping elements consisting of a layer or bundle of metal strips. Between said bare (uncovered) flat bundle of metal (steel) strips, steel cable plugs are fixed.
  • This brush element for use in a brush of a sweeping machine comprises a piece of a steel wire cable, a surrounding layer, which binds said wires and is made of a plastic material and a tear inhibitor within said layer, which allows substantial tearing of the layer in accordance with the tear of the inside steel wire cable.
  • said layer is a plastic material comprising potato starch, biodegradable polyesters etc.
  • Said plastic surrounding layer has some annular thickened portions of the plastic material to prevent tearing and further damaging of said layer.
  • this invention is only a dish brush with steel cable plugs destined for weed removing and not usable for normal sweeping activities.
  • the aim of our invention is to overcome mentioned drawbacks in order to provide a dish brush for sweeping activities and a combi dish brush for sweeping activities in combination with removing weeds from pavements.
  • Our dish brushes also have strong sweeping and noise reduction characteristics. This effect is urgently needed in municipal or urban circumstances.
  • the dish brush with noise reducing sweeping elements is characterised in that said first sweeping elements are executed as a flat holder, which is folded over 180 degrees into a double squeezed U-form, with two parallel sets in a row with two threads thin highly-graded twisted steel wire covered with a so called plastic material one with a casing thickness t and a working length L and in which said second sweeping elements are executed as usual steel cable plugs also with length L with a so called plastic covering material two with thickness r, wherein said first sweeping elements are fixed under an angle ⁇ at the raised brim and under an angle ⁇ of the centre in a first embodiment of said dish brush and under an angle ⁇ of the centre in which said first sweeping elements can be replaced by said second sweeping elements to form a so-called combi dish brush, wherein angle ⁇ is p times angle ⁇ .
  • the advantage is to create an uncomplicated dish brush, which can easily be transformed from a normal sweeping brush with first sweeping elements for only removing dirt from paved surfaces into a combi sweeping brush with first and second sweeping elements for removing dirt and weeds in one go from said paved surfaces. All these activities are executed with strongly reduced noise values.
  • the dish brush according to the invention is developed in such a way, characterised in that said plastic material one is a rubber and said plastic material two is a polyethylene, in which said rubber is an SBR-rubber filled with a percentage X of carbon black and in which said percentage X carbon black is between 20% and 40%, preferably 25%.
  • the advantages are that during sweeping activities the covering with plastic materials of the first and second sweeping elements are wearing without tearing, which can be seen when executing a test in practice.
  • the dish brush according to the invention is further developed in such a way, characterised in that said thickness t is between 0,4 mm and 1,2 mm, preferably 0,8 mm, in which said thickness r is between 1 mm and 2 mm, preferably 1,5 mm.
  • the advantages are an economical and environmental execution of the first and second sweeping elements.
  • the dish brush according to the invention is further developed in a technical way, characterised in that said dish brush is executed only with said first sweeping elements and welded or robotically welded from the top side of the raised contour brim in which said combi dish brush is executed with said first and second sweeping elements and welded or robotically welded from the top side of the raised contour brim, wherein said p is between 2 and 10, in this case preferably 5.
  • the advantages are, that a robotically welding of the first and second sweeping elements are possible in a very economic way for a normal dish brush, using only the first sweeping element for removing dirt and using a combi dish brush for removing dirt and weeds from paved surfaces.
  • Figure 1 represents a view in oblique projection of an embodiment of the dish brush 1 with only first sweeping elements 2 according to the invention.
  • the circular plate 3 of the dish brush 1 has a raised contour brim 4 under an angle ⁇ (see figure 7 ).
  • the circular plate 3 is mounted under a vertical sucking tube of a sweeping machine (not shown).
  • the first sweeping elements 2 are situated at angles ⁇ of the centre of the circular plate 3.
  • Figure 2 shows a front view of mentioned first sweeping elements 2.
  • the first sweeping elements 2 are formed as a flat holder 5, which is folded over 180 degrees to a double squeezed U-form. So, there are two parallel sets 6, 7 with six in a row with two threads thin highly-graded twisted steel wire.
  • the covering material one 9 is a rubber with a percentage X of black carbon (see also figures 7 and 9 ).
  • Figure 3 shows a side view over the line III-III of figure 2 . Same parts always have the same numbers.
  • Figure 4 shows a cross-section over the line IV-IV of figure 3 .
  • the sets 6, 7 of the first sweeping elements 2 are a set of two threads 8 with a rubber covering 9.
  • set 6, 7 has six sweeping elements 2.
  • Figure 5 shows a view in oblique projection of an embodiment of the so-called combi dish brush 10 with first and second sweeping elements 2 and 11.
  • the second sweeping elements 11 are steel cable plugs 12 with a polyethylene cover 13 (see also figures 8 and 10 ).
  • the circular plate 13 has also the same raised contour brim 15 with two different openings 16, 17 adapted to the steel head covers of the first and second sweeping elements 2, 11. Now, a robotic welding procedure is possible (not shown).
  • Figure 6 shows a top view over the line VI-VI of figure 5 .
  • the same parts have the same numbers.
  • Figure 7 shows a side view of the first sweeping element 2, which has already been described and has the same numbers.
  • Figure 9 shows the sweeping elements 6, 7 more in detail.
  • Figure 8 also shows a side view of the second sweeping element 11, which has already been described in more detail.
  • the covers 9 and 13 greatly reduce the noise during sweeping activities.
  • Figure 10 shows a cross-section over the line X-X of figure 8 .
  • the same elements have the same numbers.
