Abstract

A drive system (2) includes a rotor (11) which is driven by high pressure water exiting nozzles (16). Such a construction has the advantage that only water, and no further sources of power, is supplied to the system. The drive is used to power a floor clearing brush or pad 24 or a cutting tool for tarmacadam or concrete.

Description

DRIVE SYSTEMS The present invention relates to drive systems, and in particular, but not exclusively, to drive systems for brush tools incorporating a rotatable scrubbing brush or pad.
Currently there are a number of small rotary brushes on the market which are driven by water pressure. The designs are based on a water wheel design. Consequently, this type of brush operates at very low torque and is only suitable for use on vehicles and for wheel cleaning, since the maximum brush head diameter is around 180 mm.
It is therefore desirable to provide a high torque floor cleaning tool using a large brush/scrubbing head, which can be driven by high pressure water.
According to the present invention there is provided a drive system comprising a liquid inlet, a rotor which is rotatable about an axis, and an outlet which is carried by the rotor and which serves to direct liquid supplied through the liquid inlet in a direction to cause the rotor to rotate about the axis.
For a better understanding of the invention, and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows a side sectional view of a brush tool including an embodiment of the present invention; Figure 2 shows a plan view of the tool of Figure 1; Figure 3 shows an enlarged side sectional view of the drive system of the tool of Figure 1; and Figure 4 shows a sectional plan view of part of the drive system of the tool of Figure 1.
A brush tool 1 incorporating a drive system embodying the present invention is shown in Figures 1 and 2, and comprises a drive unit 2 which is attached to a rigid handle 4. A brush unit housing 6 is rigidly attached to the drive unit 2, and contains a brush element 24.
The handle 4 incorporates a rubber hand grip 41 and a quick release coupling water supply inlet 42.
The handle 4 is pivotally attached to the brush unit housing 6, by way of swivel hinges joints 43.
The drive unit 2 includes a water inlet connection 8, which is connected to a water pipe 10. The water pipe 10 connects via the quick release coupling 42 to a water supply (not shown) which supplies water at high pressure to the brush tool 1. Preferably, water is supplied at 1000 psi to 3000 psi from an industrial power washer.
As shown in more detail in Figure 3, a hollow water supply shaft 9 extends from the water inlet 8 and serves to support a hollow rotor 11. The shaft 9 and rotor 11 are supported on bearings 83 and are rotatable with respect to the water inlet 8 about a vertical axis. A coupling 84 is provided between the water inlet 8 and the shaft/rotor 9, 11. The coupling 84 comprises a first part which is fixed to the water inlet 8, and a second part which rotates with the shaft 9. The coupling thereby provides a rotary seal for transmission of water to the shaft 9 and rotor 11.
An output shaft 12 is attached to the rotor 11 and is rotatable with the rotor. Water is supplied into the water inlet 8, via a connection 81, and to the rotor 11, via the coupling 84 and the shaft 9.
As is more clearly shown in Figure 4, the rotor 11 carries arms 14 which define passageways 15 which extend from the rotor 11 to the free end of the arms 14. The passageway 15 communicates with the hollow rotor 11. Water supplied to the water inlet 8 is thus communicated to the free ends of the arms 14.
Each arm 14 carries a nozzle 16 which extends at right angles to the arm, i.e. in a direction at right angles to the radius of the shaft 9. Each nozzle 16 includes a passageway 17 which communicates with the passageway 15.
The rotor 11 carries an output driveshaft 12 which extends away from the rotor 11 and which carries an output gear 18. The driveshaft 12 is supported on bearings 121 in the brush unit 6.
In use, high pressure water is supplied to the water inlet 8, the water is channelled through the shaft 9 and rotor 11 along the passageways 15 and 17 and ejected from the nozzles 16. Since the water is ejected from the nozzle at right angles to the arms 14, the rotor is caused to rotate with respect to the water inlet 8 about the vertical axis. Thus, the shaft 9 and output driveshaft 12 are also caused to rotate.
Water ejected from the nozzles 16 falls through drains 19 in the motor unit into the brush unit 6. The brush head 24 can carry any type of brush or floor cleaning pad. Water ejected from the water motor is supplied to the brush or pad.
The brush unit 6 carries a driveshaft 22 which is free to rotate with respect to the brush unit, and which carries a drive gear 20. The drive gear 20 engages with the drive output gear 18, so that when the output gear 18 rotates the drive gear rotates. The shaft 22 also carries a brush head 24, so that rotation of the drive gear 20 causes rotation of the brush head 24.
Thus as will be readily apparent from the Figures, supply of high pressure water along the supply pipe 10 to the inlet 8 and through shaft 9 and rotor 11 eventually to the nozzles 16 causes the motor unit 2 to provide an output drive via gear 18 which drives the brush head 24.
Water which is discarded from the drive unit 2 is used as the cleaning solution for the brush. The water supply can be hot or cold (50C to 1200C) and an ideal flowrate would be 81/min to 201/min at a pressure of 1000 psi to 3000 psi.
The brush head can be a large head (e.g. 565 mm diameter) for floor cleaning, or could be a smaller head (e.g. around 150 mm diameter) for cleaning vehicles etc.
An embodiment of the present invention can therefore provide a simple drive system for a rotating brush tool, which does not require provision of an electrical power source, or indeed any power source, and which utilizes the water supply which would in any case be required.
The cleaning tool is particularly suited to cleaning brick paving and stone work since sand is not washed away by the cleaning action.
It will be appreciated that the drive coupling between the motor unit 2 and the brush unit 6 can be any convenient coupling.
It will also be appreciated that the motor unit 2 could be used to power other equipment requiring a rotary drive.
For example the drive system could be used to drive a floor cutting tool, the brush head of the described embodiment being effectively replaced by a cutting wheel. Such a cutting tool could be used for cutting tarmacadam, concrete etc.
