BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
This invention relates to a refuse vehicle and in particular, to a side loading refuse vehicle and more particularly, but not limited to, an automated side loading refuse vehicle for simultaneous collection, but separate storage of garbage and/or recyclable wastes in the one vehicle.
BACKGROUND ART
With the introduction of environmental awareness, the collection of domestic garbage has taken on a new complexion, it being realised that new, convenient and economical approaches to garbage collection and recycling must be introduced. It has been proposed to provide householders with a plurality of waste bins so that each householder can sought waste into various categories.
For example, paper, metal cans and bottles and garbage could conceivably be stored and collected separately and this has been tried, the main problem with this scheme is the high expense insofar as separate collections are required for each category.
The alternative has been to provide local or regional sorting facilities where garbage is hand sorted or expensive automated facilities have been tried with minimal success due to the high expense involved.
In summary therefore, sorting of recyclables from domestic garbage after collection is generally uneconomical.
OUTLINE OF THE INVENTION
The present invention has, as its primary object, to provide a useful alternative to the aforementioned prior art.
In one aspect, the present invention resides in a side loading refuse vehicle including the combination of an elongate refuse storage tank divided into longitudinally extending tank sections, a loading mechanism adjacent a side of the refuse vehicle and a refuse transfer mechanism for delivering refuse or other material emptied into the vehicle by the loading mechanism to the respective tank sections.
The storage tank typically has arcuate side walls and is preferably generally square and medially bulged in shape.
The storage tank of the refuse vehicle typically has a plurality of tank sections and typically has two or three tank sections although more tank sections may be employed.
The tank sections can comprise side-by-side or upper and lower storage regions or combinations of these. The storage regions typically have respective forward and rearward ends and respective entrances adjacent the forward ends through which refuse can enter the regions.
Typically, the tank sections have respective discharge doors with one discharge door being operatively located outside the other discharge door or doors so that the tank sections can be discharged sequentially.
Where an upper storage region is employed, it typically includes a sloping floor which slopes down toward the forward end of the upper storage region so that as the vehicle travels, the sloping floor causes compaction of refuse toward the forward end of the upper storage region.
The transfer mechanism typically includes means for receiving and selectively diverting refuse from a bin, the bin either having two compartments which are side-by-side as the bin is emptied, or having two compartments which are one above the other as the bin is emptied, the transfer mechanism operating so that refuse from the compartments is maintained separate as the refuse is moved to the respective tank sections.
The refuse transfer mechanism typically includes a passive or active mechanism or a combination of passive and active mechanisms selected from the following: means; compartment defining portion of a bin so that refuse from the bin remains separate as it flows or is moved from the bin, through the transfer mechanism and finally into the tank sections; substantially vertical axis relative to the longitudinal direction of the tank sections.
The transfer mechanism can move material within the tank sections and in one embodiment a conveyor can be used in one or more of the tank sections so that refuse can be conveyed along the tank sections. Typically, the conveyor is an endless belt conveyor or a travelling floor conveyor.
In one preferred form, the transfer mechanism t
