Description

A MACHINE FOR REMOVING LIQUID FROM A SURFACE TECHNICAL FIELD
This application relates to a machine for removing liquid from a surface, and particularly, although not exclusively, to a machine for removing surface water from playing fields and other recreational areas. BACKGROUND ART
There have been many proposals for machines intended to remove surface water from playing fields and other recreational areas. Typical of such machines is that disclosed in GB 405 796, which discloses a machine comprising a main roller provided with an absorbent outer layer, and a squeeze roller positioned to squeeze absorbed water from the absorbent layer during operation into a tank on the machine. The machine is intended to be pushed manually over the surface to be dried. A disadvantage of machines of this type is that they require great effort to push them along, which is physically exhausting for the operator. Furthermore, the power required to rotate the pressure roller is derived from the movement of the machine, and this places great strain on the absorbent cover, through which the power is transmitted. This results in rapid wear of the absorbent cover, this wear being further accelerated by the additional strain placed on the absorbent cover when the machine negotiates a turn.
GB 942 338 discloses a machine which -is powered, but this machine operates by sucking water through the perforated wall of a drum. There is no absorbent cover for the drum, and so wear problems as mentioned above do not exist. SUMMARY OF THE PRESENT INVENTION
According to the present invention, a motor is provided which drives the squeeze roller, the main roller being driven by frictional engagement with the squeeze roller.
In a machine in accordance with the present invention, the absorbent layer does not need to trans¬ mit the power required to rotate the squeeze roller to provide the squeezing action. In a preferred embodiment, the machine is moved over the surface to be dried by ground engaging means, such as wheels, other than the absorbent layer, with the result that the absorbent layer transmits only enough power to rotate the main roller.
According to another aspect of the present inven¬ tion, the main roller can be raised from the surface to be dried, which means that turning of the machine need not impose strain on the absorbent layer. Thus, broadly stated, according to this other aspect of the present invention there is provided a machine for removing liquid from a surface, the machine comprising a powered drive unit which is drivable over a surface from which liquid is to be removed, and a liquid absorbing unit which is mounted displaceably on the drive unit for movement into and out of contact with the surface.
In a preferred form of the invention, the drive unit has front and rear wheels, of which the front wheels are drivable and the rear wheels are steerable, although other arrangements are possible. For example, the front wheels may be steerable. The drive unit may have a seat for an operator of the machine. A prime mover, such as a petrol engine, is" mounted on the drive unit, and in the preferred embodiment this engine drives a hydraulic pump for providing fluid under pressure to hydraulic motors for operating the various systems of the machine. In other embodi¬ ments, direct mechanical drive may be employed, or there may be a combination of direct mechanical drive and hydraulic drive. The drive unit also preferably has a large capacity tank for receiving liquid absorbed by the water absorbing unit.
The liquid absorbing unit preferably comprises a circulating absorbent element, for example a layer of foam mounted on a rigid roller. The roller and the foam layer may be similar to those disclosed in British Patent Application No. 8203086. The water absorbing unit may also have a squeeze roller, as mentioned above, which compresses the foam material at a position on its circulating path so as to squeeze out water absorbed from the surface into a holding tank. If the drive unit has a large-capacity tank, the holding tank is connected to feed liquid to the main tank.
Preferably, the liquid absorbing unit is pivotally mounted on the drive unit for raising and lowering the liquid absorbing unit with respect to the ground. It is convenient, especially if there is a pressurized hydraulic system on the machine, for one or more hydraulic cylinders to be provided for raising and lowering the water absorbing unit. BRIEF DESCRIPTION OF THE DRAWINGS
For a better understanding of the present invention, and to show how it may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:
Figure 1 is a plan view of a machine for removing surface water from playing fields; and Figure 2 is a side view of the machine-of Figure 1. DESCRIPTION OF AN EMBODIMENT OF THE INVENTION
The machine comprises a drive unit 2 to which a water absorbing unit 4 is pivotally connected. The drive unit has front wheels 6 and rear wheels 8. The rear wheels are steerable under the control of a steering wheel 10 positioned near a seat 12 for the operator of the machine. It is sensible for the wheels 6 and 8 to be fitted with wide profile tyres in order to minimise damage to surfaces over which the machine travels.
An engine 14, such as a petrol engine, is mounted on the drive unit 2. The engine 14 drives a hydraulic pump (not shown) which supplies hydraulic fluid under pressure for the purpose of powering various motors on the machine as will be described below.
A large capacity main water tank 16 constitutes a large part of the drive unit 2. The tank 16 may, for example, have a capacity of approximately 400 litres. Mounted on the water tank 16 is a water pump 18 which is driven by a hydraulic motor supplied with fluid from the hydraulic pump connected to the engine 14. The front wheels are also driven by hydraulic motors supplied with fluid by the hydraulic pump.
The water absorbing unit 4 comprises a frame 20 in which is journalled a roller 22. The roller 22 comprises a rigid drum provided with a layer of absorbent foam material. A squeeze roller 24 is also mounted for rotation in the frame and is in contact with the roller 22 to compress the layer of foam material as it passes the roller 24. The squeeze roller 24 is rotated, in operation, by a hydraulic motor powered by hydraulic fluid from the pump driven by the engine 14. The roller 22 is thus driven by frictional engagement with the squeeze roller 24. A holding tank 26 is disposed on the frame 20 beneath the squeeze roller 24. Two double-acting hydraulic cylinder and piston units (not shown) are provided for pivoting the water absorbing unit 4 relatively to the drive unit 2, fluid being supplied to these units as required from the hydraulic pump driven by the engine 14. Also, there is pipe work for conveying water in the holding tank 26 to the main tank 16.
The water absorbing unit 4 can be raised by the hydraulic cylinders to lift the roller 22 clear of the ground. In this condition, the machine can be manoeuvred relatively easily and can travel quite quickly (that is, at a speed of approximately 20 kilometres per hour) enabling it to be driven quickly from one area of surface water to another.
When the machine reaches an area of surface water which is to be cleared, the water, absorbing unit 4 is lowered by the hydraulic cylinders, so bringing the roller 22 into contact with the ground. Further operation of the hydraulic cylinders lifts the front wheels 6 off the ground so that the weight of the machine is supported only by the steerable rear wheels 8 and the roller 22. The squeeze roller 24 is then rotated by its .hydraulic motor provided with fluid under pressure from the hydraulic pump driven by the engine 14, and this in turn drives the roller 22 by frictional engagement between the rollers 24 and 22, so causing the machine to travel over the area of playing field from which water is to be cleared. As the roller 22 travels over the ground, its foam layer absorbs water from the surface, which is carried around to the squeeze roller 24. The squeeze roller 24 compresses the foam material, so squeezing the water out of the foam material into the holding tank 26 from which it is directed to the main tank 16. From the main tank 16, the water can be pumped by the pump 18 to a point away from the playing area. This can be done either contin¬ uously or intermittently as the main tank "16 becomes full.
When the roller 22 is in contact with the ground, the machine is steerable only to a slight degree, particularly if a wide roller is used. However, because the roller can be lifted at each end of the area which is to be cleared, it is possible to turn the machine sharply to make another pass without damaging the foam covering the roller 22. The opera¬ tional speed of the machine with the roller 22 down may, for example, be in the range 0 to 10 km/h.
In a preferred embodiment of the machine, the drive unit is 195 cm long and 90 cm wide, although other dimensions may be appropriate, depending on the size of the roller. The roller 22 is 90 cm in diameter and can be in the range 50 to 250 cm in length, depending on the purpose for which the machine is to be used. A machine in accordance with the present invention can clear water from playing fields or other surfaces at a very high rate, for example at the rate of approximately 40,000 litres per hour. Furthermore, the machine can travel at a relatively high speed from one work area to another, this being of particular benefit when the machine is used on large areas- such as race tracks, golf courses and large playing fields where surface water may need to be cleared only from isolated locations. The large capacity main tank 16 means that the machine can be used to collect water on long straight runs, such as on race tracks, without requiring long hose pipes for continuously discharging the water to an off-course drain. Instead, the machine can be connected to a hose pipe only when the tank is full or, for example, at the end of each run. A major advantage of the described machine is its manoeuvrability when the roller is raised .
Although the present invention has been described primarily in connection with the removal of water from playing fields and other recreational areas, it is also suitable for mopping up spillages of chemicals and other liquids in, for example, industrial premises.
