Lightweight waste gathering and disposal vehicle with automated arm
First Claim
1. A refuse receptacle emptying apparatus for use with a utility vehicle, comprising:
- a platform configured to couple to a utility vehicle;
a turret rotatably coupled to the platform, the turret responsive to a turret actuator pivotally coupled to the turret and the platform that rotates the turret between a first position and a second position;
a fulcrum element pivotally coupled to the turret;
a substantially hollow lift arm coupled to the fulcrum element, the fulcrum element positioned between a first end of the lift arm and a second end of the lift arm such that when the first end of the lift arm is lowered the fulcrum element pivots to raise the second end of the lift arm and when the first end of the lift arm is raised the fulcrum element pivots to lower the second end;
an extendable lift cylinder pivotally coupled to the turret proximate the platform and pivotally coupled proximate the first end of the lift arm, the extendable lift cylinder configured to raise the first end of an extension arm relative to the platform when extended and lower the first end of the extension arm relative to the platform when retracted;
the extension arm being a telescoping extension arm slidably coupled at least partially within the lift arm and extendable from the second end of the lift arm responsive to an extension cylinder coupled to the extension arm and the lift arm;
a grabber pivotally coupled to the extension arm, wherein the grabber is coupled to a grabber backing plate pivotally coupled to the extension arm, the grabber comprising two curved grabber elements each movably coupled to the grabber plate;
a bag collector arm pivotally coupled to the extension arm and responsive to a bag collector motor to pivot between a retracted collector arm position and an extended collector arm position; and
a receptacle leveling actuator coupled to the grabber backing plate.

Abstract
A lightweight waste gathering vehicle is used to automate trash collection and removal from soft landscapes within recreation venues minimizing or eliminating damage to landscape. The lightweight vehicle can be used in crowded areas or areas where height, width and/or weight restrictions prevent the use of large refuse trucks. The lightweight waste gathering vehicle includes an automated arm, a tow-behind trailer and turf tires. In one implementation, the automated arm includes a lift arm type system. In another implementation, the automated arm includes a transport rail type system where the grabbers are mounted to a carrier and the carrier is mounted to a transport rail.
