Definitions

  • the present invention relates to gutter brooms and gutter broom systems for use with surface cleaning vehicles such as street cleaning vehicles, sidewalk cleaning vehicles, and factory floor cleaning vehicles, and more particularly to such gutter brooms and gutter broom systems that are dustless and that are efficient in terms of air flow use.
  • Various types of surface cleaning vehicles such as street cleaning vehicles, sidewalk cleaning vehicles and factory floor cleaning vehicles, typically use gutter brooms to sweep along curbs, against the sides of building walls, and the like.
  • the surface cleaning vehicles typically has left and right counter-rotating gutter brooms each mounted on a laterally movable arm assembly directly in front of the surface cleaning vehicle.
  • the gutter brooms range from about two feet in diameter to about four feet in diameter. Together, the two gutter brooms sweep an extended path that is wider than the surface cleaning vehicle.
  • gutter brooms create a considerable amount of dust. This dust travels freely in the ambient air. It is known in the prior to separately shroud the gutter brooms in order to contain this dust. The dust is suctioned away from the gutter broom by an air suctioning dust control system that is used to capture dust and debris.
  • the shrouding creates two significant problems.
  • the first problem relates directly to the purpose ofthe cleaning vehicle.
  • the shroud generally precludes all but very small debris from reaching the gutter broom, resulting in the ploughing of debris, such as cans and bottles, leaves, and so on. Accordingly, it is known to leave open a portion of the shroud around the gutter broom in order to permit debris to be received by the gutter broom. While this sounds like a simple solution, it actually creates the second significant problem.
  • the creation of an opening in the shroud around the gutter brooms causes a significant reduction in airflow pressure in the gutter broom shroud, thereby permitting the escape of fugitive dust and other fine particulate matter. Accordingly, the effectiveness of the dust suctioning system is significantly decreased, typically to a generally unacceptable level.
  • the second overall problem is also related to dust-laden air flow. It is of course necessary to filter the dust-laden air; however, it is common for dust filters to become readily clogged. Accordingly, it is highly desirable to minimize the amount of air flow through the filters, instead of merely presetting a level to a predetermined maximum amount.
  • a novel dust- capturing gutter broom assembly for use on a surface cleaning vehicle having a longitudinal axis and drivable forwardly along the longitudinal axis when in use.
  • the dust-capturing gutter broom assembly comprises mounting means for mounting the dust-capturing gutter broom assembly on a surface cleaning vehicle.
  • a gutter broom is operatively mounted in depending relation from the mounting means for rotation about a generally vertically extending gutter broom axis.
  • a gutter broom shroud is mounted in supported relation on the mounting means in surrounding relation to the gutter broom and defining a substantially hollow interior that houses the gutter broom.
  • An air outlet in the gutter broom shroud permits the egress of dust laden air from the gutter broom shroud.
  • the gutter broom is rotated in contact with a surface being cleaned to thereby urge debris towards a central path with respect to the surface cleaning vehicle, thereby creating an ancillary volume of dust-laden air.
  • a fan is connected in air flow relation with the air outlet of the gutter broom shroud, for causing the ancillary volume of dust- laden air to egress from the gutter broom shroud via the air outlet.
  • a gutter broom filter filters the ancillary volume of dust-laden air.
  • the gutter broom shroud defines a broom-presenting side opening for permitting said gutter broom to sweep against a lateral surface and a debris-receiving front opening for permitting ingress of debris into the substantially hollow interior of the gutter broom shroud.
  • a movable member is operatively mounted on the gutter broom shroud for selectively altering the size of the debris-receiving front opening.
  • Figure 1 is a side elevational view of the first preferred embodiment of the dust-capturing gutter broom assembly according to the present invention, in use on a mobile surface cleaning vehicle, with the movable member in a lowered position;
  • Figure 2 is a side elevational view similar to Figure 1, but with the movable member in a raised position;
  • Figure 3 is a top plan view of the first preferred embodiment dust-capturing gutter broom assembly of Figure 1;
  • Figure 4 is a top plan view of the second preferred embodiment dust-capturing gutter broom assembly according to the present invention.
  • Figures 1 through 4 of the drawings illustrate a first preferred embodiment of the dust-capturing gutter broom assembly of the present invention
  • Figure 4 illustrates a second preferred embodiment of the dust-capturing gutter broom assembly of the present invention.
  • FIGS 1 through 2 show a first preferred embodiment of the dust-capturing gutter broom assembly 20 for use on a surface cleaning vehicle 20 having a longitudinal axis and drivable forwardly along the longitudinal axis "L" when in use, and having a debris loading means 22 that produces a main volume of dust-laden air.
  • the dust-capturing gutter broom assembly 30 comprises a mounting means for mounting the dust-capturing gutter broom assembly 30 on a surface cleaning vehicle 20.
  • the mounting means comprises a mounting arm assembly 34 that permits the dust- capturing gutter broom assembly 20 to track the profile of the surface being cleaned.
  • a gutter broom 40 is operatively mounted in depending relation from the mounting arm assembly 34 for rotation about a generally vertically extending gutter broom axis "G" that is close to vertical but is upwardly and forwardly tilted, as is well known in the industry.
  • a gutter broom shroud 50 is mounted in supported relation on the mounting arm assembly
  • the gutter broom shroud 50 comprises a roof portion 52 overlying the gutter broom 40 and a skirt portion 54 depending from the roof portion 52.
  • the skirt portion 54 is flexible and is mounted in height-adjustable relation on the roof portion 52 by means of threaded fasteners.
  • the gutter broom shroud 50 also has a rear portion 56 that extends downwardly to the level of the bottom of the gutter broom 40 so as to, in use, contact the surface being cleaned.
  • the gutter broom shroud 50 defines a broom-presenting side opening 68 for permitting the gutter broom 40 to sweep against a lateral surface and a debris-receiving front opening 60 for permitting ingress of debris into the substantially hollow interior 51 of gutter broom shroud 50.
  • the debris-receiving front opening 60 and the broom-presenting side opening 68 are contiguous one with the other.
  • the dust-capturing gutter broom assembly 20 further comprises a movable member 70 operatively mounted on the gutter broom shroud 50 for selectively altering the size of the debris-receiving front opening 60.
  • the movable member is movable for selectively altering the height of the debris-receiving front opening 60, and is generally vertically movable.
  • the movable member 70 comprises a movable panel made from a material such as polyurethane and is mounted on left and right rails 71,72 for vertical movement to any selected vertical position between, and including, a lowered position as best seen in Figure 1, and a raised position as best seen in Figure 2.
  • small debris may pass under the movable member 70; however, large debris, such a cans and bottles, and leases, and so on, is blocked from entry into the substantially hollow interior 51 of the gutter broom shroud 0, and debris is generally precluded from being swept out of the gutter broom shroud 50 by the gutter broom 40. Instead, the large debris is ploughed by the pick-up head. If there is a significant enough accumulation of large debris, it could actually travel over a pick-up head or a gutter broom shroud.
  • the reasons for the movable member 70 to be in the lowered position are that only a minimum amount of air is suctioned through the debris-receiving front opening 60, thus maximizing the efficiency of the effectiveness of the dust suctioning system, which is not possible with a gutter broom system having a debris- receiving front opening with no control of the effective size of the debris-receiving front opening.
  • gutter broom shroud 50 for entry into the substantially hollow interior 51 of the gutter broom shroud 50, to be swept by the gutter broom 40, which is not possible with a gutter broom system having no debris-receiving front opening.
  • the operatively mounted includes being mounted on the gutter broom shroud 50 and alternatively elsewhere.
  • the movable member 70 could be operatively mounted on a separate arm connected to the pick-up head for instance, and still interface with the gutter broom shroud 50 in the same effective manner as described herein, and still be considered as operatively mounted on the gutter broom shroud 50.
  • the dust-capturing gutter broom assembly 20 further comprises an actuation system as indicated by the general reference numeral 75 for actuating the movable member.
  • the actuation system 75 comprises a hydraulic actuator 76 operatively connected to the movable member.
  • the actuation system further comprises a manually operable controller 74 accessible by an operator of the surface cleaning vehicle 20.
  • the manually operable controller 74 coupled to a hydraulic cylinder 76 mounted on the gutter broom shroud 50.
  • the hydraulic cylinder 76 is coupled to the movable member 70 for vertically moving the movable member 70 to a desired height.
  • the manually operable controller 74 is preferably mounted in the cab (not specifically shown) of the surface cleaning vehicle 20.
  • the motor 41 for rotating the gutter broom 40 comprises a hydraulic motor 41, or alternatively an electric motor, mounted on top of the gutter broom shroud 50.
  • the air outlet 58 is disposed in the top of the gutter broom shroud 50, but may be disposed elsewhere.
  • the gutter broom 40 is rotated when in contact with a surface being cleaned to thereby urge debris towards a central path with respect to the surface cleaning vehicle 20, thereby creating an ancillary volume of dust-laden air. It is highly undesirable to have this dust-laden air escape from the gutter broom shroud 50, without being filtered.
  • a fan 80 is connected in air flow relation with the air outlet 58, for causing the ancillary volume of dust-laden air to egress from the gutter broom shroud 50 via the air outlet 58.
