Abstract
Apparatus for removing debris from the ground comprising a frame, which supports a rotatable cylindrical brush having bristles projecting from its axis of rotation, a rotatable shaft member extending across the width of the brush, a scraper member extending across the width of the shaft member and a guide member configured arcuately to follow the outside of the brush whereby, in use, the frame is movable across the ground and the brush is in touching contact with the ground such that the bristles contact and catch any surface debris and on moving away from the ground the bristles approach the shaft member which contra-rotates with respect to the , brush such that surface debris is retained by the bristles as they move upwardly proximate the guide member which guides the debris upwardly for ejection, whilst the scraper member maintains the shaft member free of accumulated debris.
Description
CLEANING APPARATUS
This invention relates to cleaning apparatus. More especially but not exclusively the invention relates to paddock cleaners.
Horses and other animals can become infected with internal parasites by eating fodder containing the cysts and eggs of the parasites. The parasites are deposited on the ground by excretion from infected animals Accordingly if paddocks are to be kept usable it is wise to collect the animal droppings. This can be time consuming when done manually.
The invention seeks to reduce this problem. According to the invention there is provided apparatus for removing debris from the ground, the apparatus comprising:
i a ground engaging rotatable brush ii a roller generally parallel to and counter-rotatable to the brush, iii an arcuate guide disposed about the brush to guide debris carried by the brush.
Embodiments of the invention «rill now be illustrated by reference to the accompanying figures of which:
Figure 1 is a perspective view of an embodiment; Figure 2 is a scrap side elevation, and Figure 3 is a scrap front view.
OPEN TO PUBLIC INSPECTION UNDER
SECTION 28 AND RULE 23 JNL No../.%£........OF iMTrf /λνΛ'Ά * 94 0 3 0 2
The apparatus is provided with a rotatable brush
1. The brush has a generally horizontal major axis. Preferably the brush is ground engaging. Preferably the brush is cylindrical but this is not essential. If it is cylindrical the brush can rotate about the cylinder axis. The brush 1 can comprise a metallic core from which plastics, preferably polypropylene, filaments extend. Preferably the filaments are elliptical in cross-section.
Those skilled in the art will have no difficulty in devising methods of rotating the brush 1 but they include hydraulic motors, electric motors and mechanical PTO from a towing tractor. It is preferred that the peripheral speed of the brush is, in use slightly greater than the ground speed of the apparatus. A preferred brush is about 0.4-0.6m especially about 0.5m in diameter and a peripheral velocity of 2-8ms“^ corresponding to a rotation at about 100 to 300 rpm may be usable for a\ ground speed of up to 15 kmh”1 preferably 6 to 12 kmh-*.
In use the brush should brush the ground. In some embodiments of the invention an adjuster 2 is provided to adjust the position of the brush.
If desired an auto-levelling adjuster can be used.
The apparatus can be provided with a roller 3. Roller 3 can be of smaller diameter than the brush 1 for example 75 to 125 mm especially about 100 mm. Roller 3 can be made of steel. Roller 3 is preferably not ground ’ 940302 engaging but is supported so as to be preferably 10 to 50 mm more preferably 20 to 40 mm above the ground. In some embodiments the roller is supported, typically at the ends by wheels 4. Preferably the wheels are barrel shaped. The barrel form can facilitates cornering. The wheels 4 drives the roller 3 which preferably counterrotates relative to the brush 1.
The height of the brush axis above the ground can in some embodiments be varied by moving the roller 3 up or down relative to the apparatus frame. In some embodiments the roller is movable laterally relative to the frame. An arcuate guide 5 extends in part around the cylinder of rotation of the brush 1. The guide 5 is preferably of polypropylene. In some embodiments of the invention the rotating filaments touch the guide. In other embodiments they do not and may be spaced small distance away from the filament ends. In general one end of the guide is very close to or abuts the surface of the roller 3 and may act as a scraper scraping material from the roller 3. The scraper need not be integrally formed with the arcuate guide for example to allow easy changing in the event of damage. Typically the guide portion is of 3mm polypropylene and the scraper portion 10mm polypropylene.
In some embodiments the scraper is supported by a support 6. Support 6 may allow the relative positioning
0 30 2 ' of the scraper tip and the roller 3 to be adjusted. An adjuster to adjust the spacing of the guide from the brush may be provided. This or the other adjuster can comprise a pin carried in a slotted link.
In use the apparatus is moved across the area to be cleaned with the roller 3 ahead of the brush. Because the roller does not touch the ground, debris such as horse droppings are not compressed with great force into the ground. The rotation of the roller may however lift the debris. In any event much of the debris is lifted by the rotating brush. It is then forced into between the rotating brush and guide upwardly and rearwardly. The distance projected can be varied by varying the speed of the brush.
The ejected debris can be collected in a hopper 10 for disposal for example by sale- Conveniently the hopper 10 is pivotally mounted (for example at 11) on the apparatus. Rotation of the hopper allows the collected debris to be discharged. Conveniently the hopper may be rotated by hydraulic rams 12.
The apparatus will generally carried on wheels 13 although those skilled will have no difficulty in devising other carriages. In the embodiment shown castors are used for manouverability.
The skilled will be able to devise locomotive embodiments but the illustrated embodiment is tractor * 94030 2 drawn and provided with a conventional tow connector and a drive for taking power from the power take off of the tractor.
Where the apparatus of the invention is used to clean long grass it may be desirable to provide a further brush. This brush if present is generally situated in front of the first brush, guide and roller. In general terms it is similar to the first brush although the filaments may often be more rigid. The second brush is driven in the same direction as the first brush. In use the second brush lifts debris from the ground to a point part way up the long grass or possibly to the top of it. The first brush can then project it into the hopper as hereinbefore described.
As mentioned previously the invention is not restricted to the collection of animal droppings. It may be used to collect mown grass. Where this is done it is sometimes found that the cuttings encounter a standing wave of air and are not cleanly collected in the hopper. One way of overcoming this problem is to make one (or more), preferably the top, surface of the hopper foraminous such as of fine netting. A standing wave may then not be formed.
It is preferred that brush roller and guide are carried on a subframe 14 which is articulated for example by a pivot 15 to the tractor hitch point carried on a
9*030 2 1 frame 16. This decouples to an extent the brush from the tractor and reduces the tendency of the brush to leave the ground if the apparatus traverses rough ground. The castor wheels in this case are conveniently carried at the rear of the device on the main frame.
