Power-assisted arm for mobile vacuum trash collector

摘要

A mobile vacuum trash collector comprised of a motorized cart, a frame connected rearwardly of the cart, a bin mounted on the frame, a lid removably connected to the bin and a flexible hose connected to the lid at one end and having a nozzle at the other end. The hose is held via a rigid supporting arm above an operator's head and is maneuverable by the operator using a telescopic arm which interconnects an intermediate portion of the hose via the arm and the nozzle. A vacuum motor is mounted at the bottom of the bin for drawing airborne trash through the hose and downwardly into the bin. An air permeable bag is suspended in the bin for collecting the trash, the air bag being drawn downwardly and out of the bin via an exhaust port. Because suction is provided continuously downwardly through the bin, large quantities of debris are sucked into the bag and compressed or compacted. Furthermore, because the motor is mounted at the bottom of the bin, the entire apparatus has a low center of gravity and is very stable when moving over inclines and curbs.
