Definitions

  • the invention refers to the rotary cleaning brushes, driven by the pressure of the cleaning water. Brushes of this type are described, for example, in the Italian patents application Nos. 3325 A/79, 4744 B/79 that contemplate the use of one brush to clean the bottles, keyed onto the axis of a small Pelton turbine driven by the pressure of the water taken from the watermains, which in part is fed axially through the same brush to arrive at the interior of the bottle overturned in the phase of washing. It is also known a hydrobrush for the same use, described in the patent application No. 29009 B/81, in which the cleaning brush is driven by means of a speed reducing gear, that makes it possible to increase the torque transmitted to the same brush, in order to make with this latter a more strong cleaning.
  • hydrobrushes of the type described in the Italian patent No. 1.214.945 dated 1-3-1985, particularly suitable for the washing of surfaces, provided with a handle connected at one end to a flexible duct for feeding the water under pressure and which with the other end is integral with a body containing the impeller of the turbine placed onto an axis perpendicular to the one of the said handle.
  • the axis of the turbine is hollow and is traversed rotatably by the axis of the rotary brush which co-operates with a speed reducing gear placed in the above mentioned stator and driven by a small toothed wheel axially integral to the said impeller.
  • Prior to this hydrobrush were known hydrobrushes described, for example, in the USA patent No.
  • the hydrobrushes of the known and above mentioned type present the drawback that have the speed reducing gearing very close to the rotating cleaning brush, so that said gearing can be easily reached and damaged by the dirty removed from the surface cleaned by the rotating brush.
  • Another drawback is represented by the high noise of said gearing.
  • the invention intends to obviate to these and other drawbacks of the known prior art, with an hydrobrush in which the speed reducing gearing is distant from the impeller and confined inside a little box, with the side walls obtained integral with the bell shaped body of the same hydrobrush and closed downwardly by the flat body of the impeller of the turbine, or by a lid for example snap assembled onto the edge suitably shaped of said walls.
  • the box containing said gear is provided with suitable openings, for example in the corner zones, to allow the free passage to the water entering in the same box, also to ensure a sufficient lubrication of said gear.
  • reference numeral 1 indicates the overturned cup shaped body made of plastic of the said hydrobrush, provided with the hollow handle 2 also made of plastic material arranged with the end 102 for the connection with a flexible duct for feeding the water under pressure and provided on the other end that opens in said body 1, with the nozzle 3 oriented tangentially with respect to the impeller G of the turbine and from which comes out the jet of water under pressure that will determine the rotation of the said impeller G.
  • the annular body 4 made of plastic material, that houses seats 104 for the support of bristles 5 suitable to form an annular and fixed brush SF, that has the function of a skirt for the containment of the water sprays generated by the said hydrobrush.
  • spokes integrals with the body 4 and with a bushing 304 placed axially in the centre of the said body 4, and in which there is inserted one bushing 6 which is traversed in a rotating manner by the shaft 107 that, with its end is mounted rotatably, with the interposition of one reinforcement bushing 8 made of material with low coefficient of friction, in one blind seat 9 obtained in the centre of the base of the body 1.
  • the shaft 107 made of plastic material, carries integrally a toothed wheel 7 that meshes with a smaller toothed wheel 10 made also of plastic material, rotatably assembled on one pin 11 integral with the bottom of the body 1 and sheathed by means of one reinforcement bushing 8 made of material with low coefficient of friction.
  • a toothed wheel 13 Integral and with an axial alignment with the toothed wheel 10, there is provided a toothed wheel 13 which has, for example, the same number of teeth of the toothed wheel number 7 and which meshes with a small toothed wheel 14, substantially equal to the toothed wheel 10, obtained integral on one end of the hub 114 of the impeller G which is hollow and which is mounted rotatably on one reinforcement bushing 15 made of material with low coefficient of friction, which covers the said shaft 107.
  • the toothing of the gear above mentioned can be, the whole or in part, straight or inclined.
  • With reference numeral 214 are indicated the spokes of the impeller and with the reference numeral 314 are indicated the vanes of the same impeller G which is obtained by means of injection of plastic material inside a mold.
  • the shaft 107 is realised with an axially hollow shape for constructive requirements and because on the tapered and preferably toothed end 207 of the same, that comes out from the bushing 304 of the body of the fixed brush SF, there is keyed and fixed by means of the screw 16, the central attachment 117 of the body of the rotary brush SR, the bristles of which are embedded in the holes 18 obtained onto the wide spokes of said body ( Figure 6).
  • the speed reducing gear 7-14 is housed in a box S the side walls of which are obtained integral with the bottom wall of the body 1 which is provided in elevation with openings 20 placed, for example, in the corner areas.
  • the box S can be closed with clearance by the body of the impeller G, if differently as it is shown by the drawings said body would be closed superiorly, otherwise it is closed by means of an applied lid 21, provided with small truing projections 121 and with teeth 221 that snap co-operates with conjugate parts 119 obtained onto the internal sides of the walls 19, as shown in the Figures 4-6.
  • the lid 21 is provided with a hole 22 traversed with large clearance by the toothed wheel 14 of the impeller G, as shown in Figure 5.
