Abstract

A method and apparatus for cleaning generally hard-to-reach or inaccessible areas uses a turbine blower attached to at least one duct for blowing debris located in the hard-to-reach or inaccessible area into an accessible area. The apparatus is most typically mounted on a street-cleaning machine that collects debris as the machine is driven over the debris. The duct can be directionally adjusted from a driver'"'"'s position of the street-cleaning machine. Air flow volume per unit time can be adjusted from the driver'"'"'s position. The debris is moved using the apparatus from the inaccessible or hard-to-reach area into an area that permits the street-cleaning machine to be driven over the debris to collect the debris.

Claims

1. A cleaning apparatus comprising:

a wheeled chassis;

a device operable to collect debris located on a surface traveled over by the chassis attached to the chassis;

at least one blower attached to the chassis, at least one blower being capable of generating an air flow of at least 6,500 cubic feet per minute; and

duct attached to at least one of the blower, the at least one duct adapted to direct the air flow toward an area adjacent to the chassis, wherein the air flow can be generated independently of the device operable to collect debris, and wherein a volume per unit time of the air flow is adjustable.

2. The apparatus of claim 1 wherein at least one duct is directionally adjustable relative the chassis.

3. The apparatus of claim 1 further comprising a device adapted to remotely control a volume per unit time of the air flow and a direction of at least one duct.

4. The apparatus of claim 1 wherein the at least one duct comprises a valve for selectively reducing an air flow volume per unit time of the at least one duct.

5. The apparatus of claim 1 wherein the apparatus is adapted to direct the air flow while the apparatus is operating to collect debris being traveled over by the chassis.

6. The apparatus of claim 1 wherein the apparatus is adapted to direct the air flow while the apparatus is operating at full capacity in a function of collecting debris being traveled over by the chassis.

7. The apparatus of claim 1 further comprising an instrument, attached to the at least one duct, adapted to reduce the air flow.

8. The apparatus of claim 7 wherein the instrument is adapted to selectively reduce air flow through the at least one duct.

9. The apparatus of claim 8 wherein the instrument is adapted to reduce the air flow responsive to an air-flow threshold.

10. The apparatus of claim 8 wherein the instrument adapted to selectively reduce the air flow is responsive to a device operable to remotely control a volume per unit time of air flow.

11. The apparatus of claim 1 wherein the apparatus is operable as a regenerative-air street-cleaning machine.

18. The apparatus of claim 10 wherein at least one duct is directionally adjustable.

19. The apparatus of claim 10 wherein the apparatus is adapted to adjust a volume per unit time of the air flow.

12. A cleaning apparatus comprising:

a wheeled chassis;

a device operable to collect debris located on a surface traveled over by the chassis attached to the chassis;

at least one blower attached to the chassis at least one blower being capable of generating an air flow of at least 6,500 cubic feet per minute; and

duct attached to at least one of the blower, the at least one duct adapted to direct the air flow toward area adjacent to the chassis, wherein the air flow can be generated independently of the device operable to collect debris; and

wherein at least one duct is directionally adjustable via a device adapted to remotely control a direction of the air flow.

13. The apparatus of claim 12 wherein:

the at least one blower comprises a first blower and a second blower;

the first blower generates the air flow directed by the at least one duct; and

the second blower generates a second air flow for collecting of the debris traveled over by the chassis.

14. The apparatus of claim 12 further comprising a device adapted to remotely control a volume per unit time of the air flow and a direction of at least one duct.

15. The apparatus of claim 12 wherein the at least one duct comprises a valve for selectively reducing an air flow volume per unit time of the at least one duct.

16. The apparatus of claim 12 further comprising an instrument adapted to reduce the air flow.

17. A cleaning apparatus comprising:

a wheeled chassis;

a device operable to collect debris located on a surface traveled over by the chassis attached to the chassis;

at least one blower attached to the chassis at least one blower being capable of generating an air flow of at least 6,500 cubic feet per minute;

duct attached to at least one of the at least one blower, the at least one duct adapted to direct the air flow toward an area adjacent to the chassis, wherein generation of the air flow does not diminish a capacity of the apparatus to simultaneously collect debris being traveled over by the chassis; and

an instrument, attached to the chassis, adapted to reduce the air flow.

20. The apparatus of claim 17 wherein at least one duct is directionally adjustable via a device adapted to remotely control a direction of the air flow.

21. The apparatus of claim 17 further comprising a device adapted to remotely control a volume per unit time of the air flow and a direction of at least one duct.

22. The apparatus of claim 21 wherein the apparatus is adapted to direct the air flow while the apparatus is operating to collect debris being traveled over by the chassis.

23. The apparatus of claim 21 wherein the apparatus is adapted to direct the air flow while the apparatus is operating at full capacity in a function of collecting debris being traveled over by the chassis.

24. The apparatus of claim 17 wherein the instrument is adapted to selectively reduce the air flow through the at least one duct.

25. The apparatus of claim 24 wherein the selective reduction of the air flow occurs responsive to an air-flow threshold.

26. The apparatus of claim 24 wherein the instrument adapted to selectively reduce the air flow is responsive to a device operable to remotely control a volume per unit time of air flow.

27. The apparatus of claim 17 wherein the air flow can be generated independently of a function of the apparatus of collecting debris being traveled over by the chassis.

28. The apparatus of claim 17 wherein an entire air-flow generation capacity of the at least one blower can be channeled through the at least one duct.

29. The apparatus of claim 17 wherein:

the at least one blower comprises a first blower and a second blower;

the first blower generates the air flow directed by the at least one duct; and

the second blower generates a second air flow for collecting of the debris traveled over by the chassis.

30. The apparatus of claim 17 wherein the apparatus is operable as a regenerative-air street-cleaning machine.
