• wood, waste, yard, brush, organic, matter, and derivatives thereof are meant to be used and defined in its broad, general, and ordinary sense, and the terminology is meant to include material such as stems, branches, twigs, leaves, grass, and the like, or anything else that could otherwise be deposited, recycled, reduced, or otherwise processed from a site or yard, as is generally known within the art.
• waste, brush, collection, and processing system, and derivatives thereof, and as applied to the waste and brush collection and processing system of the disclosed invention are meant to be used and defined in its general and ordinary sense.
• systems that recycle, reduce, or otherwise process wood and brush products include, generally, vacuums, blowers, mulchers, chippers, shredders, grinders, and the like.
• an exemplary prior art yard waste collection system 2 includes the primary components of a base 4, a motor 5, and a housing 6, an inlet chute 7, and an outlet chute 8.
• these systems further comprise a fan or rotor (not shown) disposed in the housing 6 for inducing a vacuum in the inlet or inlet chute 7, for processing the yard waste (e.g., mulching) within the housing 6, and for expelling the yard waste through the outlet or discharge chute 8.
• the configuration of these prior art systems is such that the outlet 9 of the housing 6 is generally disposed upwardly (e.g., discharging generally vertically as opposed to horizontally) while the discharge chute 8 is curved so as to direct the discharged stream of waste material into the truck bed (e.g., discharging generally horizontally as opposed to vertically). That is to say that while the outlet is generally vertical, the discharge stream which is desired is generally horizontal, creating a discharge angle a.
• any curvature of the discharge chute will result in a reduced pressure and restriction of flow and discharge of the particles.
• the prior art system illustrated in Fig. 1 utilizes a bend which is 90 degrees and thereby causes increased resistance, decreased pressure, decreased wind/discharge velocities, and decreased flow. Accordingly, this increases the likelihood that the discharge chute will become obstructed or clogged, whereby the obstructions must then be cleared before normal operation may resume and continue.
• top discharge systems are a system wherein the outlet 9 is disposed, open to, and directed towards and above a centerline C (e.g., by an angle a) as depicted in Fig. 1. These top discharge systems have been used in order to vertically lift and then horizontally direct the discharged stream of material into the truck bed or trailer, the trailer generally being higher or above ground level.
• a curved discharge system is a system wherein the outlet 9 or outlet chute 8 comprises a channel which is curved or otherwise restrictive as compared to a straight channel. Again, these discharge systems have been used in order to lift and then direct the discharged stream of material into the truck bed or trailer.
• Yet another disadvantage is that the prior art systems do not allow for the regulation and directional control of the discharged stream of particles. For example, in systems that discharge into a truck bed, and after a certain amount of debris is collected, piles of debris are formed in the bed. This often results in non-uniform loading of the bed and as such, either the collection system, and more often the truck must be moved to facilitate an even and uniform loading of the truck bed and for maximum loading capability.
• Still another disadvantage is that such existing systems are not adapted to be disposed on or otherwise connected to other waste processing systems such as, for example, wood chippers, stump grinders, and the like.
