Abstract

A leaf collecting machine 20 has a fan 12 which applies suction through a hose 13, to suck-up leaves and other debris. The outlet of the fan 12 passes through a first duct portion 19 to a second duct portion 5, disposed within a cabinet 6. Both the duct portion 5 and the cabinet 6 are porous, to allow the exhaust of air therethrough. Leaves and other debris fall from the duct portion 5 to a nip defined between a pair of rotating steel rollers 3. The leaves and debris are compressed between the rollers and fed positively into a tubular chamber 14, at one end of which there is closely fitted a refuse sack 1. When the chamber 14 is full, an hydraulic ram 8 is operated to eject the compressed leaves and debris into the plastic sack 1. <IMAGE>

Description

SPECIFICATION Leaf collecting machines This invention relates to leaf collecting machines.
As every gardener, park keeper and local council knows, it can be a very time consuming task to collect leaves every Autumn. More often than not, this is still done by hand, the leaves being raked or swept into a pile, which is then transported to a rubbish dump, or possibly burnt.
Sometimes, street cleaning machines are used, operating on the principal of a large vacuum cleaner.
Such machines suck-up leaves and any other litter, which are collected in a bag. The problem with using such a machine is that, although it will suck-up leaves together with other litter quite well, the bag will fill quickly with leaves, due to their low packing density.
The invention aims to provide a leaf collecting machine which may be improved in this respect.
According to a first aspect of the present invention, there is provided a leaf collecting machine comprising suction means for sucking leaves into the machine, a chamber for collecting the leaves in the machine, feeding means adapted to feed leaves from the suction means into the chamber until the chamber is packed tightly with leaves, and discharge means adapted to discharge the packed leaves from the chamber.
Preferably, the feeding means comprises a pair of rotary elements, adapted to feed leaves into the chamber through a nip defined between said elements. The rotary elements may with advantage comprise rollers (for example, of steel), and the rotary elements may be urged resiliently towards a position in which they contact one another.
In a preferred arrangement, said chamber is elongate, and has a longitudinal opening through which said feeding means is adapted to feed leaves into the chamber. The chamber may be of circular cross-section.
Preferably, said discharge means is adapted to discharge packed leaves from said chamber in a direction which is generallly orthogonal to that in which the leaves enter the chamber.
The discharge means may with advantage comprise a ram, which is preferably an hydraulic ram.
The chamber preferably has a discharge port around which a container may engage to receive packed leaves discharged from the chamber. Preferably, there is provided at least one bag which is adapted to fit closely around said discharge port to receive packed leaves discharged from said chamber. Said discharge port is preferably disposed at the end of a tubular part of said chamber, around which said bag may be closely fitted with the bottom of the bag adjacent the discharge port. The bag may with advantage comprise a plastics refuse sack.
The suction means preferably comprises a fan and a duct extending between the fan and said feeding means, at least part of the duct being perforated or porous to vent air. The said part of the duct is advantageously perforated to vent air and dust particles, and may with advantage be disposed within a compartment which is porous to vent air but not dust particles.
The said duct may terminate above said feeding means, and in such an arrangement, there is preferably provided at least one inclined guide plate to guide leaves delivered from the duct into said feeding means.
Said part of said duct may be preceeded by a duct portion having imperforate and non-porous walls.
Preferably, there is provided at least one hydraulic motor for driving said feeding means, and/or at least one hydraulic motor for driving said suction means.
The machine preferably includes an hydraulic pump for powering the or each hydraulic motor. Preferably, the machine further includes a prime mover for driving said hydraulic pump, which prime mover may be an internal combustion engine.
Said suction means may comprise a flexible hose for the intake of leaves.
The leaf collecting machine is preferably provided with support means permitting movement of the machine over the ground. Preferably, such support means comprises wheels. Alternatively, however, the support means may be adapted to support the machine on an air cushion, and to this end, may utilize the air flow developed by the suction means.
The machine may be adapted for self-propelled movement.
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 diagrammatic drawing, the single figure of which is a perspective view of a leaf collecting machine embodying the invention.
The illustrated leaf collecting machine 20 comprises a fan 12 which is arranged to provide suction to a flexible hose 13, which is adapted to suck leaves, together with any other litter or debris, into the machine 20.
The outlet of the fan 12 is connected to a duct 9, which has a first duct portion 19 leading to a second part 5 of the duct, which is disposed within a cabinet 6. The first duct portion has walls which are both imperforate and non-porous. However, the second part 5 of the duct has perforated walls through which air and dust particles can pass. The walls of the cabinet 6 are finely porous, to allow the passage of air therethrough, but not the passage of dust particles.
The second part 5 of the duct 9 terminates above a pair of downwardly inclined guide plates 18, which lead to a pair of rotating steel rollers 3. The steel rollers 3 are mounted on a sprung steel bracket 2, which serves to bias the rollers resiliently towards a position in which they contact one another. Each of the steel rollers 3 is adapted to be driven by a respective hydraulic motor 7.
The steel rollers 3 are mounted above a longitudinal chamber 14, which is of circular cross-section.
The chamber 14 is formed with an elongate opening 4, above which the rollers 3 are positioned. The chamber 14 is open at one end, to define a discharge port 15, around which a plastics refuse sack 1 is closely fitted. At the other end of the chamber 14, there is disposed an hydraulic ram 8, which is adapted to drive a plunger which fits closely within the chamber 14, up and down the chamber 14.
A diesel engine 11 is provided to drive an hydraulic pump 10, which in turn supplies the hydraulic motor 7 and the hydraulic ram 8. Moreover, the hydraulic pump 10 preferably supplies a further hydraulic motor, which is adapted to drive the fan 12. The pump 10 may provide permanent outlets to the hydraulic motor 7, hydraulic ram 8, and the hydraulic motor for the fan 12. Alternatively, the hydraulic pump 10 may have a first outlet which is permanently connected to the hydraulic motors 7, and a second outlet which is normally connected to the hydraulic motor for the fan 12, but which can be diverted therefrom to drive the double acting hydraulic ram 8. Thus, when the ram 8 is operating, the fan 12 is not driven.
Operation of the leaf collecting machine 20 will now be described briefly.
The diesel engine 11 is started, to drive the hydraulic pump 10, and thereby power the hydraulic motors 7 for the steel roller 3, and the hydraulic motor for the fan 12. The hydraulic ram 8 is initially retracted. Leaves, together with any other litter or debris, are sucked up the flexible hose 13, by the suction created by the fan 12, and are carried with the air stream through the duct 9 into the cabinet 6.
The air is vented through the perforated walls of the second duct portion 5, and through the porous walls of the cabinet 6. Leaves and other large items and particles are deposited from the bottom of the second duct portion 5 onto the nip between the steel rollers 3, into which they are guided by the guide plates 18. Smaller particles which pass through the walls of the second duct portion 5 may gradually accumulate on the guide plates 18, which guide them down into the nip between the steel rollers 3.
The rotating steel rollers 3 compress the leaves and other material between them, and feed them into the chamber 14, through the elongate opening 4. The leaves are progressively fed into the chamber 14 until it is losely filled. However, the rollers 3 then continue to compress the leaves between them and feed them into the chamber 14, until the chamber is tightly packed with leaves.
During this time, the plastics refuse sack 1 has been fitted closely over the end of the chamber 14, such that the bottom of the sack 1 covers the discharge port 15 closely. When the chamber 14 is sufficiently full, the hydraulic ram 8 is operated, to eject the contents out of the discharge port 15, thereby filling the sack 1, which is progressively removed from the end of the chamber 14. When the sack 1 has been filled, it is removed from the end of the chamber 14, and replaced with a fresh sack. The hydraulic ram 8 is withdrawn, and the chamber 14 is again filled with leaves.
It is to be appreciated that one of the important features of the leaf collecting machine 20 is that, when the leaves are packed tightly within the chamber 14, the pressure containing them therein acts generally radially. Thus, as the leaves are pushed into the sack 1 by the hydraulic ram 8, the pressure within the leaves continues to act generally radially outwardly, such that the leaves tend to be retained under pressure within the sack 1, rather than tending to escape out of the top of the sack.
Suitable means may be provided for detecting when the chamber 14 is sufficiently full as to require emptying. When the hydraulic ram is operated, it is preferred that no further leaves are fed into the chamber 14. To this end, the motor driving the fan 12 may be stopped whilst the hydraulic ram is operating (as has been outlined earlier), andlorthe hydraulic motor 7 for the steel rollers 3 may be stopped.
Thus, the leaf collecting machine is particularly advantageous for collecting leaves in sacks, the leaves being compacted to a considerable degree.
Although it is described as a leaf collecting machine, for which use it is principally intended, it will be appreciated that it may be used for sucking up and collecting other items of litter, debris, etc., which no doubt would tend to be sucked up with leaves anyway.
The leaf collecting machine 20 is preferably mounted on a chassis for wheeled movement. It may be made to a relatively small scale, for domestic or light industrial use, or maybe made to a larger scale for commercial use. If desired, it may be powered for self propulsion. As an alternative to wheels, the exhaust from the fan 12 (with further assistance if necessary) may be used to support the machine 20 on an air cushion.
As an alternative to the rollers 3, there may be used at least one auger adapted to feed the leaves and other debris into the main chamber 14. Such an arrangement would not provide so much compression of the leaves as they are fed into the chamber 14, but may provide a more positive feed of material into the chamber 14.
