Definitions

  • the present invention relates to dustless pick-up heads sweeping vehicles, and more particularly to dustless pick-up heads of sweeping vehicles wherein dust and other small particulate debris are also substantially removed from the surface being cleaned, without introducing the dust and other fine particulate matter into the ambient air.
  • Many conventional surface cleaning vehicles employ an elongate cylindrically-shaped sweeping broom that rotates about a horizontal axis sweeps the dirt and debris either onto a conveyor, into a hopper, or into a debris suctioning air stream.
  • Such surface cleaning vehicles can remove large amounts of dirt and debris from a paved surface quite quickly and thoroughly, and can generally remove large pieces of debris quite readily.
  • they cannot remove dirt and debris from significant depressions, cannot thoroughly clean a paved surface, cannot clean out a porous surface and cannot effectively remove dust and other fine particulate matter from a surface.
  • the action of the sweeping vehicle in general can cause dust and other fine particulate material to become airborne, as can the wind if the dust and other fine particulate matter are left on the surface being cleared.
  • very fine particulate material such as "PM10” and “PM2.5”, which refer to respirable particulate material or dusts with an average aerosol diameter of less than 10 microns or 2.5 microns, respectively.
  • This fine particulate material is generally considered as a health risk to humans. It is well known that this fine particulate material can cause breathing problems, especially to more susceptible individuals, and the long term effects of breathing this fine particulate material can seriously affect one's health. Accordingly, legislation exists in many jurisdictions to preclude surface cleaning vehicles from emanating such fine particulate material during sweeping operations.
  • the cleaning of dust and other fine particulate matter from the surface being cleaned, after it has been swept, should work in harmony with the air suctioning system that suctions the dust and other fine particulate matter from the broom shroud.
  • Patent No. 6,195,836 issued March 6, 2001, to Vanderiinden. That patent discloses a mechanical surface sweeping vehicle having a cylindrically-shaped rotating sweeping broom that propels fbrwardly debris disposed on a contacted portion of a surface being cleaned, thereby creating a fbrwardly propelled stream of debris.
  • An air blast outlet effects a blast of air that forcefully impinges in a forward direction the surface behind the leading edge of the broom, thereby propelling fbrwardly therewith fine debris disposed on the surface.
  • the dust suctioning pick-up head comprises a shroud defining a fore-art longitudinal axis, and has a substantially hollow interior, a bottom edge defining a bottom opening, and a fonvardly facing debris outlet for permitting the directed egress of debris from the shroud as a fonvardly propelled stream of debris.
  • At least one cylindrical main sweeping broom is disposed within the substantially hollow interior of the shroud for engaging a surface to be cleaned through the bottom opening to thereby sweep dust and debris from the surface to be cleaned and propel the dust and debris fonvardly through the forwardly facing debris outlet.
  • a dust suctioning nozzle apparatus has a dust receiving mouth in fluid communication with a dust transfer outlet collectable in fluid communication with a source of air suctioning.
  • the dust receiving mouth is in fluid communication with the substantially hollow interior of the shroud so as to suction air therefrom, and is disposed vertically adjacent the bottom edge of the shroud so as to be in dust suctioning relation to the surface being cleaned, and rearwardly of the at least one cylindrical main sweeping broom to thereby permit the suctioning of dust from the surface to be cleaned subsequent to the surface being swept by the at least one cylindrical main sweeping broom,
  • the dust suctioning pick-up head comprises a shroud defining a fore-aft longitudinal axis, and has a substantially hollow interior, a bottom edge defining a bottom opening, and a forwardly facing debris outlet for permitting the directed egress of debris from the shroud as a forwardly propelled stream of debris.
  • At least one cylindrical mam sweeping broom is disposed within the substantially hollow interior of the shroud for engaging a surface to be cleaned through the bottom opening to thereby sweep dust and debris from the surface to be cleaned and propel the dust and debris forwardly through the forwardly facing debris outlet.
  • a dust removal apparatus has a dust receiving mouth in fluid communication with a dust transfer outlet connectable in fluid communication with a source of air suctioning.
  • the dust receiving mouth is in fluid communication with the substantially hollow interior of the shroud so as to suction air therefrom, and is disposed rearwardly of the at least one cylindrical main sweeping broom to thereby permit the removal of dust from the surface to be cleaned subsequent to the surface being swept by the at least one cylindrical main sweeping broom.
  • a novel sweeping vehicle having a dust suctioning pick-up head
  • the sweeping vehicle comprises a main body for carrying the dust suctioning pick-up head.
  • a shroud defines a fore-aft longitudinal axis, and has a substantially hollow interior, a bottom edge defining a bottom opening, and a forwardly facing debris outlet for permitting the directed egress of debris from the shroud as a forwardly propelled stream of debris.
  • At least one cylindrical main sweeping broom is disposed within the substantially hollow interior of the shroud for engaging a surface to be cleaned through the bottom opening to thereby sweep dust and debris from the surface to be cleaned and propel the dust and debris forwardly through the forwardly facing debris outlet
  • a dust suctioning nozzle apparatus has a dust receiving mouth in fluid communication with a dust transfer outlet connectable in fluid communication with a source of air suctioning.

  • the dust suctioning pick-up head 20 comprises a shroud 30 also defining the fore-aft longitudinal axis "L” and having a substantially hollow interior 32, a bottom edge 34 defining a bottom opening 36 that forms the bottom entrance to the substantially hollow interior 32.
  • the forwardly facing debris outlet 38 is for permitting the directed egress of debris therefrom as a forwardly propelled stream of debris past a ramp 39.
  • the forwardly propelled stream of debris may be received by an elevator and transported to a hopper, or maybe received directly by a hopper.
  • main sweeping broom that in the first preferred embodiment comprises a main sweeping broom SO disposed within the substantially hollow interior 32 of the shroud 30 for engaging a surface to be cleaned through the bottom opening 36 and sweeping dust and debris from a surface being cleaned and propelling dust and debris forwardly through the forwardly facing debris outlet 38.
  • the main sweeping broom 50 defines an effective width "W" oriented transversely to the longitudinal axis "L" when the dust-suctioning pick-up head 20 is in place on the sweeping vehicle 22.
  • the dust suctioning pick-up head 20 of the present invention further comprises dust suctioning nozzle 60 mounted within the substantially hollow interior 32 of the shroud 30.
  • the dust suctioning nozzle 60 has a dust receiving mouth 62.
  • the dust suctioning nozzle 60 comprises a single dust suctioning nozzle and is disposed rearwardly of the main sweeping broom 50 preferably such mat the dust suctioning nozzle 60 is adjacent the main sweeping broom 50, such that the dust receiving mouth 62 is in fluid communication whh the substantially hollow interior 32 of the shroud 30. Further, the dust receiving mouth 62 generally faces the surface to be cleaned.
  • the dust suctioning nozzle 60 with a dust transfer outlet 64 connectable in fluid communication with a source of air suctioning via an upper conduit portion 66, specifically the air suctioning system of the sweeping vehicle 22.

Further, the dust suctioning nozzle apparatus 60 has a fore-aft distance that is less than the fore-aft surface contact measurement of the at least one cylindrical main sweeping broom SO. Also, the ratio of the fore-aft distance of the dust suctioning nozrie apparatus to the width of the dust suctioning nozzle apparatus is greater than 25:1, and is preferably about 50:1.

It can also be seen in the drawings that there is substantially no gap between the dust suctioning nozzle apparatus 60 and the rear portion of the shroud 30, to thereby preclude dust from settling rearwardly of the dust suctioning nozzle apparatus 60. This is highly advantageous in that the dust suctioning nozzle apparatus 60 provides an effective final cleaning of the surface to be cleaned and leaves no settled dust.
  • an upper rear portion of the shroud 30 is shaped for deflecting overthrown debris from the at least one cylindrical main sweeping broom 50 forwardly of said dust suctioning nozzle apparatus 60 to substantially preclude the overthrown debris from landing on the dust suctioning nozzle apparatus 60.

  • the second preferred embodiment dust suctioning pick-up apparatus 220 is similar to the first preferred embodiment dust suctioning pick-up apparatus 20 except that the dust suctioning nozzle apparatus 260 is integrally formed with the shroud 230.
  • FIG. 10 shows a third preferred embodiment of the dust suctioning pick-up apparatus of the present invention, as indicated by general reference numeral 320.
  • the second preferred embodiment dust Suctioning pick-up apparatus 320 is similar to the first preferred embodiment dust suctioning pick-up apparatus 20 except that the nozzle is a slightly different form of a dust removal apparatus 360» namely a recirculating air type dust removal apparatus.
