Abstract

A mobile vacuum trash collector comprised of a motorized cart, a frame connected rearwardly fo 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 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.

Claims

1. A vehicular vacuum trash collector comprising a motorized cart for carrying a human operator, a bin connected to the rear of said cart, a hose connected at one end to said bin and having an inlet at the other end thereof, means for maneuvering said hose and nozzle independently of said cart, means for emptying said bin, a vacuum blower disposed within and at an opposite end of said bin from said hose for drawing debris via suction into said nozzle, through said hose and into said bin, further including air permeable means within said bin intermediate said one end and said vacuum blower for trapping said debris within the bin, said vacuum blower further comprising at least one fan for drawing airborne debris into said bin, said debris being trapped in said air permeable means.

2. A vacuum trash collector as defined in claim 1 wherein said air permeable means comprises an air permeable bag for trapping said debris within the bin.

3. A vacuum trash collector as defined in claim 2 wherein said vacuum blower is comprised of a plurality of rotating fans.

4. A vacuum trash collector as defined in claim 3 wherein said plurality of fans are centrifugal fans.

5. A vacuum trash collector as defined in claim 2, 3 or 4, wherein said vacuum blower comprises:

(a) an upper rotating fan for drawing airborne debris downwardly into said bin, said debris being trapped in said air permeable bag, and drawing air centrifugally outwardly toward the periphery thereof;

(b) a stationary air guide having a plurality of straight fins for directing said outwardly drawing air axially inward toward the centre thereof, and;

(c) a lower rotating fan for drawing said inwardly directed air downwardly and centrifugally outward toward an exhaust port, wherein each of said upper rotating fan and lower rotating fan includes a plurality of curved fins disposed in a nautilus pattern.

6. A vacuum trash collector as defined in claim 2, 3 or 4 wherein said air permeable bag is comprised of jute.

7. A vacuum trash collector as defined in claim 2, 3 or 4 wherein said air permeable bag is comprised of porous plastic material.

8. A vacuum trash collector as defined in claim 2, 3 or 4 wherein said air permeable bag is comprised of fibrous polypropylene.

9. A vacuum trash collector as defined in claim 3 wherein said plurality of fans are disposed on a rotating shaft driven by a motor.

10. A vacuum trash collector as defined in claim 1, 2 or 3, further including a lid for said bin, said hose being connected to said bin through said lid.

11. A vacuum trash collector as defined in claim 1, 2 or 3, wherein said vacuum blower comprises a pair of centrifugal fans and a stationary air guide disposed therebetween.

12. A vacuum trash collector as defined in claim 1, 2 or 3 further including an exhaust port in said bin for venting air from said bin.

13. A vacuum trash collector as defined in claim 1, 2 or 3 further including an exhaust port in said bin for venting air from the bin, and means connected to said exhaust port for filtering airborne dust particles vented from said bin.

14. A vacuum trash collector as defined in claim 2 wherein said at least one fan is disposed on a rotating shaft driven by a motor.

15. A vacuum system as defined in claim 1, wherein said vacuum blower is connected to said bin at the center of gravity of said trash collector, thereby contributing to the stability of said cart.

16. A mobile vacuum trash collector comprising:

a vehicle, a frame connected to said vehicle, a bin mounted on said frame, a hose connected to one end of said bin, said hose having an inlet at an opposite end thereof, and vacuum means within and at an opposite end of said bin from said hose, for sucking debris into said inlet, through said hose and into said bin, wherein a suction path is provided from said one end to said opposite end of the bin, further including a rigid support arm pivoted to said frame, for carrying said hose, means for resiliently supporting said hose carried by the arm, means for providing vertical and horizontal swinging movement to said hose carried by said arm, and means for adjusting the vertical equilibrium position of said arm.

17. A mobile vacuum trash collector as defined in claim 16, further including an air permeable bag disposed within said bin, for trapping airborne debris but allowing air to pass therethrough.

18. A mobile vacuum trash collector as defined in claim 17, wherein said vacuum means is comprised of at least one rotating fan.

19. A mobile vacuum trash collector as defined in claim 16, 17 or 18 wherein said vacuum means is comprised of at least one centrifugal fan.

20. A mobile vacuum trash collector as defined in claim 16, 17 or 18 wherein said vacuum means is comprised of a pair of centrifugal fans and a stationary airguide disposed therebetween.

21. A mobile vacuum trash collector as defined in claim 16, 17 or 18 wherein said bin is pivotally connected to said frame for tilting between a first trash receiving position and a second trash emptying position.

22. A mobile vacuum trash collector as defined in claim 16 17 or 18 further including a lid removably connected to said bin and immovably mounted to said frame, said bin being mounted in a slotted pivot to said frame such that in the event said lid and bin are disconnected, said bin drops under the influence of gravity, within said slotted pivot, to a position clear of said lid, for tilting between an upright trash receiving position and a tilted trash emptying position.

23. A mobile vacuum trash collector as defined in claim 16, 17 or 18 further including a door disposed in said bin, through which debris may be emptied.

24. A mobile vacuum trash collector as defined in claim 17 or 18 further including means for filtering airborne dust particles carried by said air which have passed through said air permeable bag.
