Definitions

  • the present invention concerns dish brushes, which are normally mounted under an upstanding axle of a street sweeper machine. Usually weed and garbage/dirt has to be removed from paved surfaces such as streets and other pavements without and with joints. Most dish brushed are executed to remove dirt and garbage. Dish brushes are also developed for removing weed between the pavement.
  • EP 3560378 a special Dish Brush for Sweeper Machines is described and disclosed. This known patent application is a first step in partly fabricating the dish brush with robot welding technology and for practical use has still disadvantages in production costs, mechanical strength/properties and mechanical life time.
  • the dish brush is further developed in an inventive way. So, an optimal dish brush is obtained in a mechanical and economical way. In the same rotating procedure, an optimal dish brush is obtained in a technical and economical way for weeding and sweeping activities.
  • the circular plate for a combined weed and sweep dish brush according to the invention is characterized in that said flat sweeping elements and said steed cable plugs are fastened with welds from the upper side through a set of small slit openings in a radial equidistant sense at said raised contour edge of the adapted circular plate with thickness d and diameter D, wherein said slit openings for said flat sweeping elements have a set of two L-formed openings and said slit openings for said steel cable plugs have a set of two partly circular slit openings, wherein said slit openings have a width w.
  • the advantage is, that a fully robot welded dish brush with excellent mechanical strength is obtained at minimal costs and minimal production time.
  • the excellent mechanical strength of the welds is obtained by the configuration of the shape of said slit openings.
  • the circular plate according to the invention is further developed characterized in that the circular connecting area of the steel cable plugs under the contour edge of the circular plate are upwardly mechanically deformed.
  • the advantage is a further mechanical strengthening of the steel cable plugs by upwardly deforming the contact area of the top of the steel cable plug.
  • the circular plate according to the invention is further developed characterized in that said slit width w for welding activities is between 3 mm and 7 mm, preferably 5 mm.
  • the advantage is an optimal slit width w for a robotic welding procedure as happened to be in practice.
  • the circular plate according to the invention is further developed characterized in that said angle alpha ( ⁇ ) is between 20 degrees and 40 degrees, preferably 30 degrees.
  • the advantage is a dish brush with an optimal angle to the paved surfaces.
  • the circular plate according to the invention is further developed characterized in that said plate thickness d is between 2 mm and 6 mm, preferably 3 mm and diameter D is between 300 and 800 mm, preferably 400 mm, 450 mm, 500 mm and 640 mm, wherein said centre angle beta ( ⁇ ) is between 5 degrees and 15 degrees, preferably 9 degrees.
  • the advantage is to construct the dish brush in different dimensions to fit sweeping machines and execute special jobs.
  • Figure 1 shows a top view of the spread-out circular plate 1 according to the invention, which is deformed to a circular plate 2 with a raised contour 3 (see figure 2 ). Under said raised contour 3 the flat circular elements 4 and the steel cable plugs 5 are fixed by means of robotic welding through the set of L-formed slit openings 6 and the set of partly circular slit openings 7. See figures 6 and 7 .
  • Figure 2 shows the upwardly deformed circular connecting area 8 for placing said steel cable plugs 5, which are welded through partly circular slit openings 7, also see figure 5 .
  • the angle alpha ( ⁇ ) is usually around 30 degrees, but can be adapted to specific applications.
  • Figure 3 shows a pure bottom view of the circular plate of figure 2 .
  • the same parts have the same numbers.
  • Figure 4 shows a cross section of the line A-A in figure 3 . Shown is the angle alpha ( ⁇ ) of the raised contour 3.
  • Figure 5 shows an enlarged cross section X of figure 4 .
  • the detail shows the mechanical upwardly deformed circular connecting area 8 for said steel cable plugs 5 (not shown).
  • Figure 6 shows an oblique view of a fully constructed dish brush according to the invention. The same parts have the same numbers.
  • Figure 7 shows a top view in an enlarged scale of the dish brush of figure 6 .
