Definitions

  • the present invention relates to a universal motor sweeper unit consisting substantially of a cylindrical rotating and conveying brush contained in an external box which can be coupled to self-propelled or towed means through structures and/or moving arms which are fixed or extensible with adjustable positioning and extension.
  • the cylindrical brush and the conveyor are powered and include integral or separate means of collection and suction.
  • Said universal unit is applicable singly or in pairs to self-propelled or towed vehicles or vehicles with moving arms, preferably combined with main central transverse rotating brushes with fixed position equipped or interconnected with boxes for containment of the sweepings.
  • conical rotating brooms with vertical axis which, individually or in pairs, rotate in such a manner as to collect sweepings at their periphery and convey them to the centre of the machine in which are arranged the collection and suction means.
  • the horizontal transverse rollers have the drawback that they are not capable of effectively collecting the sweepings along borders and/or edges.
  • Said devices which allow effective use in variable width paths such as corridors and the like and/or with variable height such as steps, although they are of course valid, display some drawbacks.
  • conical brushes which, as already mentioned, in their rotary action raise a lot of dust.
  • the obstacle-sensing devices are of the electronic type, very sensitive and delicate and basically very costly.
  • the subject matter of the present invention is elimination the above mentioned shortcomings.
  • the invention as characterized in the claims solves the problem by means of a universal unit for motor sweepers by means of which there are achieved the following results.
  • the unit equipped or not with collection and suction means for the sweepings can be applied on any mobile vehicle, self-propelled or towed.
  • Each unit comprises at least one rotating brush with cylindrical bristles with a coupled conveyor element with helical bristled or with a belt with transverse entrainment blades.
  • Each unit or pair of units is supported by a moving fixed or telescopic arm or by means adjustable laterally, transversely and in height.
  • the cleaning unit can be made up of a combination of rotating cylindrical brushes with helically arranged bristles with substantially parallel axes and of which one is preferably fixed in a central position and the others are front and lateral with the capability of extension outward.
  • Said lateral brushes are extended mechanically, manually or electronically and are preferably combined with rotating screw conveyors for conveyance of the sweepings toward the centre of the unit and a large central brush and/or aspirator.
  • the motor sweeper machine as a whole and in accordance with the disposition of the above mentioned cleaning brushes can be of the self-propelled type or the manually moved type.
  • the combination of large horizontal cylindrical brushes with helical bristles allows perfect collection of sweepings and any refuse even if heavy.
  • the combination of helical rotating conveyors with the front brushes allows reliable and total collection of refuse and sweepings in general with no manual finishing work.
  • the motor sweeper system whether self-propelled or manually moved, is easy to maneuver, includes filters for purification of the suction air and a sweepings collection box and is capable of operating on surfaces between a minimum width corresponding to the length of a fixed cylindrical central brush and a maximum width corresponding to the sum of said length of the central brush and the lengths of the front brushes extended laterally.
  • FIGS. illustrate universal units (1) for motor sweepers and the like substantially consisting of an external box (2) which includes a lower opening (3) from which projects the peripheral end of a powered cylindrical brush (4) coupled with a conveyor (5) or (6) inserted in a seat (7) substantially parallel with said brush.
  • the rotating brush (4) is preferably cylindrical with bristles parallel or in a single or double helical spiral converging toward the centre while the conveyors may be cylindrical (5) or helical spiral, also with bristles, or with laminations of rigid material, or they can consist of conveyor belts (6) supported by end rollers (8) and equipped with transverse entrainment blades (9).
  • the direction of travel of the box is from right to left as viewed in FIGS. 3 and 4 and the direction of rotation of the rotating brush is clockwise, again in accordance with the above mentioned FIGS.
  • the peripheral end of said brush (4) slides on the ground (10), collects the refuse and raises it while rotating to dump it into the seat (7) of the conveyor (5) or (6).
  • the refuse is then pushed or collected by the conveyor (5) or (6) until it reaches the mouth of the suction duct (11). Then it is sucked in and made to fall in to extractable collection boxes (12) while the suction air is appropriately purified through filters (13) and expelled to the atmosphere through the blowers (14).
  • the units (1) for motor sweepers and the like are separated by the suction, collection and filter units (15) and are configured in such a manner as to allow easy application to the end of the fixed or telescopic moving and rotating arms (16) arranged on the self-propelled vehicles (17) or trailers, or positioned at the front, side or rear of vehicles (17) especially conceived for said use or vehicles adaptable for the purpose at the time of need such as for example material handling trucks (18), tractors (19) and the like.
  • suction, collection and filter units (15) are the conventional ones applied on vehicles (17) or are configured in an independent and adequate manner for being applied to any means of transport.
  • FIGS. 1 and 2 illustrate a motor sweeper with variable width substantially consisting of a structure (100) on wheels and on which is positioned a first cylindrical brush (21) having bristles arranged from the periphery toward the centre in an opposing helical manner (50).
  • the main brush (21) is powered by means of belts, chains, gears or the like and positioned at the centre of the structure (100) and is oriented in such a manner that the ends of its bristles sweep the ground and is supported at the ends by fixed supports.
  • box structures (2) which are opposed and extensible outside the periphery (110) of the structure (100) in the directions indicated by the arrows (112) in FIG. 2.
  • This extension is independent or simultaneous and is preferably but not in a limited manner provided by opposed pistons (113) fixed on one side (114) to the fixed structure (100) and on the other side (115) to the moving boxes (2) open on the bottom which slide along transverse guides (116).
  • the sliding movement of the boxes (2) can be provided also by different means such as mechanical devices and the like without going outside the scope of the invention.
  • each box (2) is installed a first brush with helical bristles (4) preferably but not in a limited manner oriented with the horizontal axis placed substantially parallel to that of the central brush (21).
  • This preferred orientation can however be different, i.e. the axis of each brush (4) can be oblique to the axis of the main brush (21).
  • Each brush (4) is rotated by means of appropriate gears and is positioned in such a manner that the ends of its bristles touch the ground in the zone in front of that touched by the central main brush (21).
  • the sweepings are lifted and substantially dumped into seats or trough-like tanks (7) oriented parallel to said brushes (4).
  • the conveyors (5) or (6) with bristles, paddles, belts or the like, also having rotary or translative motion.
  • the seats or trough-like tanks (7) can be equipped with an opening with a flexible manifold (20).
  • the sweepings collected by the brushes (4) are thus dumped into the tanks (7) and the powered conveyors (5) and/or (6) push them toward the central zone of the machine from which they are made to fall at ground level aligned with the central main brush (21) or are sucked in through the manifolds (20) or even undergo the combined action of the two above mentioned conditions.
  • the sweepings are collected by the brushes (4) in front of and/or beside the central main brush (21) and are then redistributed to the centre thereof in such a manner as to facilitate the collection and suction action. Said action can be combined with the suction action produced through the manifold (20).
  • the capability of lateral extention of the box structures (2) allows the use of the motor sweeper in narrow zones not smaller than the space occupied (110) of said motor sweeper and in broader zones where it is possible to extend one or all the of box structures (2).
  • the rear suction channel (70) and the flexible manifolds (20) are connected in the rear part of the motor sweeper, allowing dumping of the sweepings into the extractable box (12).
  • the suction air is taken back toward the outside through filters (13) by means of powered blowers (14) preferably arranged opposite openings (124) provided in the sides of the motor sweeper.
  • the filters (13) can be the fixed type, extractable and/or interchangeable, or mounted on vibrating systems with cams, excentrics or the like which allow their beating even during operation. Said device aids self-cleaning and dumping of refuse in the collection box (12) below.
  • the rear part (125) is used, for example, for containing the electric power batteries of the travel control motor.
  • power can be provided by internal combustion motors or others.
  • a system e.g. with cams connected to at least one piston or equivalent, permits raising and/or lowering of the motor sweeper structure in relation to the ground level (10). In this manner the action of the brushes (4) can also be exerted on planes above ground level as for example steps and the like.
  • the self-propelled version includes a driver's seat (132), a steering wheel (133) and a control panel (134) from which the operator can operate the described operating devices.
  • This solution is preferably equipped with rear steering wheels (102).
  • a rear handlebar on which are located the controls.
  • the sweepings collection box (12) and the air filters (13) are preferably extractable from the rear part of the structure (100).
  • Said boxes (2) being operated independently or simultaneously by the operators.
  • the universal units (1) for motor sweepers and the suction, collection and filter units (15) are assembled in single blocks optionally combined with a central rotating main brush (21) of the conventional type having the function of completing the refuse collection phase and conveying said refuse into the collection boxes (12).
  • the universal units (1) can be present individually as shown for example in figures 7 and 8 in relation to applications to the ends of moving rotating arms (16) or in replacement of the forks of forklift trucks (18) or they can be double and opposed with lateral extension possible, simultaneously or independently, as shown in the application to the supports of a tractor (19) in FIG. 9 or to specially conceived vehicles (17) as shown in FIG. 5.
  • Traversing of the universal unit (1) is achieved by means of the coupling of a lead-nut (25) with a powered lead screw (26).
  • the lead-nut (25) is connected to the box (2) which includes bushes (27) which run along a transverse guide (28).
  • Rotation of the cylindrical brush (4) and the conveyor (5) is provided for example by means of a hydraulic motor (29) which drives a grooved bar (30) on which is engaged a toothed belt (31) which meshes with the gears (32) and (33) keyed onto the axles of said brush (4) and conveyor (5).
  • the configuration described of the translating movement of the units (1) is given by way of nonlimiting example. Indeed, it can be of another type such as for example that shown in FIG. (10) in which the translations are achieved by pistons (34) and powering of the rotating brushes (4) is direct on their axles with internal branches for the conveyors (5) and (6).
  • FIG. 10 also shows a double and opposed application of the universal unit (1) on a fixed structure which, in addition to allowing translation of the units in accordance with the arrows (22), is capable of rotating around the central fulcrum (23) in accordance with the arrows (24) and move vertically in accordance with the arrows (38) by utilizing the movement of a conventional moving arm (16).
  • the universal units (1) for motor sweepers are preferably equipped with a front suction chamber (44) peripheral to the seat of the cylindrical brush (4) and through which is taken in the first dust which the flexible front blades (45) encounter during travel and brushing against the ground.
  • FIG. (11) shows another embodiment of the universal unit (1) with an arrangement of the conveyor means (5) or (6) orthogonal to the cylindrical brush (4).
  • the seat (7') containing the conveyor (5) has substantially the form of a hopper with a lower channel in which is inserted said conveyor, which can be either the helical bristle type (5) or belt (6) type with transverse entrainment blades (9).
  • FIG. 12 shows schematical top views of some examples of possible configurations of the systems applied for example to self-propelled vehicles (17) and shown in sequential operating phases from below upward in accordance with the numbers 1, 2 and 3 in spaces containing many obstacles (46) such as for example plants, pillars, receptacles, poles, constructions and the like.
  • obstacles such as for example plants, pillars, receptacles, poles, constructions and the like.
  • the self-propelled vehicle comprises two front universal units (1) adjustable in transverse extension and rotating around the fulcrums (23).
  • the engaged unit (1) In travel (from bottom to top), in the presence of an obstacle (46), after striking the obstacle the engaged unit (1) is capable of rotating around its fulcrum (23) while the vehicle (17) continues its travel. After passing beyond the obstacle the unit (1) returns to its normal operating position, i.e. at a right angle to the vehicle.
  • the self-propelled vehicle (17) includes a moving arm (16) to the end of which is constrained a double universal unit (1) similar to the one shown in FIG. (10).
