Abstract

A fly waste removing system comprising a self-propelled cleaning truck for removing fly waste and the like and a fly waste discharging station. A blower and a suction duct connected to the blower are carried on a self-propelled truck, and a fly waste storing box is located between the suction duct and the blower with a suction opening of the duct opened to a floor.

Claims

1. A fly waste removing system comprising a self-propelled cleaning truck which includes a self-propelled truck, a blower, a first suction duct connected to the blower and having a suction opening for sucking fly waste and the like, and a fly waste storing box located between said blower and said first suction duct, said blower, first suction duct and fly waste storing box being carried on said self-propelled truck, a fly waste discharging station, programmed to stop at predetermined times at said fly waste a mechanism in said fly waste storage box for discharging a mass of fly waste collected within the fly-waste storing box, said mechanism comprising a communicating member which includes a cylindrical member extending through an opening in a top wall of the fly waste storing box, a funnel-shaped member formed in an integral relationship with the cylindrical member, and a movable lid member which is located adjacent an opening at the top of the communicating member selectively to close the opening of the communicating member and mounted for pivotal motion on the fly waste storing box.

2. A fly waste removing system comprising a self-propelled cleaning truck which includes a self-propelled truck, a blower, a first suction duct connected to the blower and having a suction opening for suckig fly waste and the like, and a fly waste storing box located between said blower and said first suction duct, said blower, first suction duct and fly waste storing box being carried on said self-propelled truck, a fly waste discharing station, a mechanism in said fly waste storage box for discharging a mass of fly waste collected within the fly-waste storing box, said mechanism comprising a communicating member which includes a cylindrical member extending through an opening in a top wall of the fly waste storing box, a funnel-shaped member formed in an integral relationship with the cylindrical member, and a movable lid member which is located adjacent an opening at the top of the communicating member selectively to close the opening of the communicating member and mounted for pivotal motion on the fly waste storing box, said fly waste discharging station including a discharging duct installed to cooperate with said communication member when the self-propelled cleaning truck stops, and a movable cylindrical member supported at a lower end portion of the discharging duct, said movable cylindrical member being mounted for up and down movement along the discharging duct and urged downwardly by a spring whereby a top end face of the communicating member is closely contacted with the bottom face of the movable cylindrical member to establish a discharging passage for a mass of fly waste when the truck arrives at the discharging station.

3. A fly waste removing system comprising a self-propelled cleaning truck which includes a self-propelled truck, a blower, a first suction duct connected to the blower and having a suction opening for sucking fly waste and the like, and a fly waste storing box located between said blower and said first suction duct;

said blower, first suction duct and fly waste storing box being carried on said self-propelled truck, and a fly waste discharging station;

(a) said first suction duct including an entrance passage and being open to said fly waste storing box, a first filter downstream from said storage box forming one wall of said storage box, a second passage between said first filter and said blower, and a second filter between said second passage and said blower to isolate fly waste from said blower;

(b) said blower comprising a demountable blower box on said truck having an inlet in communication with said second passage and said first duct, a motor in said blower box, a fan provided in the blower box to be connected to and rotated by the motor, and an air outlet port formed on the blower box so that negative pressure is produced in said first duct connected with the blower to accumulate the fly waste on said first filter within said fly waste storing box, said blower box including the motor, fan and air outlet being independently removable from said truck to allow selective replacement with a blower box of varying capacity.
