DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
This invention relates to refuse compactors and more particularly to a small self-contained compaction unit which is designed to be emptied by a conventional front-loading or rear-loading compactor vehicle.
BACKGROUND ART
The waste industry is always looking for ways to improve the volumeric efficiency and environmental integrity of waste storage containers while reducing overall costs. The simplest way to improve the volumeric efficiency of a storage container is to compact the waste mechanically inside the container, thereby increasing the density of the waste.
Current designs of front-loading or rear-loading containers can only have their contents compacted by coupling the container to a separate, fixed compaction head. This system has several disadvantages including high spillage and leakage rates during the separation and discharge operations. Furthermore, the compaction head must be permanently fixed to the ground thereby limiting its versatility and requiring the assignment of a permanent designated access area.
Another problem encountered by waste authorities is that in high density applications such as the cities of Europe, Asia and The Middle East the space and access restrictions caused by narrow streets and parked vehicles are such that conventional compactor vehicles cannot get close enough to the waste product to operate efficiently. The current solution to this problem is the use of high numbers of collectors who push hand-carts through the streets manually loading the waste product and returning to a central collection point where they wait for a truck mounted compactor. At this stage the waste product is transferred from the cart to the compactor and the collector resumes the run with his empty cart. Although this system may be acceptable when labour rates were very low, spiralling labour costs demand that an effective alternative be found.
SUMMARY OF INVENTION
According to the present invention there is provided a refuse compactor comprising a storage chamber or container having an opening thereto, a lid for closing the opening and a compaction blade arranged to compact the waste material within the storage chamber or container.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side elevational view of a refuse compactor according to one embodiment of the invention with the lid open,
FIG. 2 is a view similar to FIG. 1 with the lid closed,
FIG. 3 is a view similar to FIG. 2 with the compaction blade in operation,
FIG. 4 is a side elevational view of the compactor shown in FIG. 1 from the other side showing a bin unloading mechanism,
FIG. 5 is a front view of the compactor shown in FIG. 1,
FIG. 6 is an enlarged view of the locking mechanism shown in FIGS. 1 to 3,
FIG. 7 is an enlarged view of the compactor blade and cutter bar shown in FIGS. 2 and 3,
FIG. 8 is a plan view of a refuse compactor according to a second embodiment of the invention,
FIG. 9 is a front view of the refuse compactor shown in FIG. 8,
FIG. 10 is a perspective view of a refuse compactor according to a second embodiment of the invention with the lid closed,
FIG. 11 is a side elevational view of the compactor shown in FIG. 10 with the lid open,
FIGS. 12 to 19 show the manner of operation of a further embodiment of the compaction system, and
FIG. 20 is a side-elevational view of a refuse compactor according to a third embodiment of the invention.
The refuse compactor 10 shown in FIGS. 1 to 5 includes a storage container 11, a lid 12, a compaction blade 13 and a self-contained power unit 14.
The storage container 11, in this instance is nominally of 3 cubic metre capacity and is formed into a semicircular shape with flat sides from light gauge sheet steel and then fully welded to provide a totally leak-proof container.
The semicircular shape eliminates square corners where waste product can stick and generate rust. The shape also simplifies the construction, reduces the number of welds and thereby significantly improves the manufacturing costs.
A set of castor type wheels 15 are fitted to the base o
