Definitions

  • the invention relates to a sweeper in an embodiment according to the preamble of claim 1.
  • Mounted sweepers of the aforementioned type are used in particular for cleaning halls, stables, factories, walkways and the like.
  • the brush roller of conventional machines is rotatably mounted in the side walls of the housing and is often provided with a hollow roller body in which a motor drive is concealed, so that the machine is quite compact and floor cleaning along walls is relatively easy to do.
  • Height-adjustable support wheels are generally provided for supporting the machine on the floor, but these do not allow the brush roller brush to be adapted to uneven floors during the cleaning run.
  • a satisfactory cleaning of depressions on the bottom, for example troughs in stables and halls can therefore only be achieved by accepting time-consuming adjustment work on the support wheels with an interrupted cleaning run and additional manual cleaning work.
  • sweepers of the type mentioned at the outset with a collecting container are known, the filler opening area of which is assigned to the sweeper roller brush and comprises a leakage protection in the form of a triangular leakage protection profile which partially delimits the container collecting space in the sweeping operating position.
  • the leakage protection profile is intended to prevent, in particular, fine-grained, dry dust and sand particles from escaping, as well as dirt adhering to the container filling area, e.g. B. prevent muddy debris. Since the collection container is to be emptied via the filler opening in a swiveled down or folded down position, the spout protection angle profile may only have a small height in order to be able to empty the container. In the known machines, it is therefore almost inevitable that in the course of the sweeping operation, dirt from already swept surfaces will occur as a result of dirt emerging on the collecting container.
  • the primary aim of the present invention is to create a sweeper of the type mentioned at the outset with little construction effort, with which dirt surfaces provided with bumps such as channels can be cleaned in a simple manner with a satisfactory cleaning result.
  • a machine is to be created which can also be equipped in such a way that garbage can be effectively prevented from escaping from the collecting container during structurally simple means, but the emptying process can nevertheless be carried out in a simple manner in terms of handling.
  • the invention is primarily based on a sweeper according to the preamble of claim 1 characterized by its characterizing features.
  • the up and down movable holder of the brush roller brush allows the cleaning of uneven dirt surfaces in a simple manner. This also applies to relatively narrow floor depressions such as troughs in stables, halls and the like. And for dirty areas with wide floor elevations or depressions.
  • the up and down movable bracket of the sweeper can be accomplished with the roller lifting arms arranged to be longitudinally movable in the vertical guides with little overall construction effort, even with automatic height adjustment of the roller brush.
  • force accumulators are preferably assigned to the roller lifting arms, which are expediently designed as pressure springs that can be supported on the machine housing and on the roller lifting arms.
  • the pretension of the springs can be adapted to given unevenness of dirt surfaces by arranging a threaded spindle or the like.
  • a leakage protection in the form of a pivotable flap is preferably provided.
  • the flap that effectively secures the collecting container in the sweeping mode against the discharge of waste is to be transferred to an almost completely free open position for emptying the collecting container, so that it can be designed freely with regard to the prevention of dirt leakage and in its closing position in a sufficient position Dimensions can limit the container collection space.
  • the flap is preferably designed as a freely movable pendulum flap that can be supported on the bottom of the collecting container, the pivot axis of which runs at a distance above the bottom of the container and parallel to it.
  • a freely movable pendulum flap supported on the container base also offers the possibility of tapping the container base by means of the pendulum flap by means of swiveling movements of the collecting container and loosening any stuck dirt residues.
  • the illustrated in the drawing embodiment of the sweeper according to the invention has a machine housing, generally designated 1 with front and rear boundary walls 2 and 3, an upper housing cover 4 and lateral housing walls 5 and 6, which the overall designated 7 brush roller brush in the upper region surrounds.
  • a support wheel 8 fastened to the front boundary wall 2 and two support wheels 9 fixed to the rear boundary wall 3 are provided.
  • the support wheels 8 and 9 can be made continuously adjustable in height.
  • the brush roller brush 7 is mounted so that it can be driven by a hydraulic motor 12 about a horizontal axis of rotation 11 oriented transversely to the running direction (arrow 10 in FIG. 1).
  • the brush roller brush 7 has a hollow roller body 13 which extends over a partial longitudinal region of the brush brush and in the interior of which the hydraulic motor 12 is arranged in a protected manner.
  • the hydraulic motor 12 can be of conventional design and comprises a connecting line 14 leading to a hydraulic pump, a screw connection 15 for the hydraulic connections 14 and a shaft drive pin 16.
  • the hydraulic motor 12 is held on the machine housing 1 by support plates 17, round bars 18 and belt plates 19.
  • the shaft journal 16 of the hydraulic motor 12 is non-positively connected to a square hollow section 22 by means of a driver connection designated overall by 21, on the outer surface of which, in the exemplary embodiment illustrated, a total of four webs 23 welded to the roller hollow body 13 are arranged at a 90 ° angular distance from one another (FIG. 3) which extend to the end of the sweeping roller brush 7 opposite the hydraulic motor 12.
  • the webs 23 extend to the outer surface of the hollow roller body 13 and wear together with the hollow roller body 13 bristle rings 24.
  • the square hollow section 22 is reinforced by stiffening ribs 25, which are also welded to the hollow axle body 13.
  • the sweeping roller brush 7 is fixed at one end via a fastening plate 26 to a roller lifting arm 27 and at the other end is mounted in an extension 28 of a second roller lifting arm 29.
  • the roller lifting arms 27 and 29 are designed as square hollow profiles, so that the hydraulic connecting line 14 can be arranged in a concealed manner in the roller lifting arm 27. 1, 4 and 5 illustrate, the roller lifting arms 27, 29 are arranged in vertical guides 30 which are fastened to the side walls 5 and 6, respectively, and can be moved longitudinally.
  • the vertical guides 30 are each formed by U-profile pieces which are welded to the machine housing 1.
  • Each roller lifting arm 27 or 29 is assigned an energy accumulator, which in the exemplary embodiments shown is formed by a compression spring 31 which can be fixed on one end on the support attachment 32 fixed to the machine housing and on the other end on a threaded spindle 33 which can be supported on the respective roller lifting arm 27 or 29.
  • a fastening projection 34 is provided with a threaded bore, so that the tensioning of the compression spring 31 can be changed by means of the threaded spindle 33.
  • the broom roller brush is held on the machine housing up and down and adjusts itself under the influence of its own weight and the compression spring 31 floor depressions and can be deflected vertically upward at floor elevations.
  • the height adjustment of the brush roller brush 7 takes place even in the case of only very narrow recesses in the floor, for example in the case of narrow troughs where the support wheels 8 and 9 are already in place support both at a higher ground level.
  • the compression spring 31 is compressed, so that when higher floor levels are reached, the compression spring 31 supports or causes the brush roller to be raised.
  • the stroke of the sweeping roller brush 7 can be influenced in an advantageous manner.
  • the parts necessary for moving the brush roller brush 7 up and down are limited to largely conventional components.
  • the laterally provided roller lifting arms 27, 29 and the vertical guides 30 allow the machine to be built compactly in connection with the internal hydraulic motor arrangement, so that a cleaning trip along the housing walls is easy to carry out.
  • the sweeper illustrated in the exemplary embodiments has a support frame which is arranged on the housing cover 4 and is numbered 35 overall and has lateral support bars 36 and 37 for inserting a fork of a forklift truck.
  • the lateral support bars 36 and 37 are connected to one another by a transversely arranged support bar 38.
  • the support beam 38 is fastened to the sweeper by carrying pockets 39 and 40, which are welded to a support plate fastened to the machine housing cover 4 and overlap the support beam 38 at a vertical distance (FIG. 1). If the height of the forklift fork remains unchanged, the sweeper can also adapt to uneven floors due to the vertical distance.
  • the collecting container 41 can be seen, which is arranged in front of the sweeping roller brush 7 in the running direction (arrow 10) of the sweeper.
  • the collecting container 41 is held movably by means of support arms 42 fastened to the side walls 5 and 6 and can be folded down or closed via a swivel linkage provided with a lifting cylinder 43 and generally numbered 44 from the sweeping operating position illustrated in FIG. 7 into the emptying position illustrated in FIG. 8 swivel.
  • the container base 45 of the collecting container 41 which is open towards the brush roller brush, carries a dustpan 47 on the front edge located in the filler opening area 46, via which the brush brush brush 7 carries the Garbage feeds to the container storage area, generally numbered 48.
  • the filling opening area 46 of the collecting container 41 is assigned a leakage protection designed as a pivotable flap 49.
  • this leakage protection is designed as a freely movable pendulum flap which extends along the end edge region of the collecting container 41 facing the sweeping roller brush 7 and is pivotally mounted in the container side walls.
  • the bearing points of the pendulum flap 49 are provided at a distance above the container base 45, so that the pivot axis 50 of the pendulum flap 49 extends above the container base 45 and extends parallel to it. Due to its own weight, the flap 49 is supported in the sweeping operating position of the collecting container 41 (FIG. 7) on the container bottom 45, so that the brush roller brush 7 first brings the rubbish into the container collecting space via the flexible sweeping strip 47 and then via the flap 49.
  • the flap 49 is designed as an isosceles angle in cross section.
  • the flap 49 is to be supported on the collecting container by means of a pivot axis 51 which is variable in position.
  • the collecting container side walls are spaced apart from one another on a circular arc around a container side wall bore 52, which each have a different vertical distance from the container base 45.
  • an articulated sleeve 54 is provided which is fastened to the flap 49 and into which a square joint bolt 55 which can be pushed through the hole recesses 53 is inserted on both sides of the machine housing 1.
  • the insertable into the joint sleeve 54 square joint bolt 55 offers u. a. especially compared to a cylindrical hinge pin the advantage that it is difficult, for. B. due to corrosion, stuck in the sleeve 54 and can be released relatively quickly in the event of jamming.
  • flat iron 56 is attached as a flap adjuster, which can be fixed on the side of the collecting container by means of a screw that can be inserted through the bore 52 in different inclinations to the container bottom 45.
  • the flap adjuster 56 can be secured by an additional screw connection in the holes 57 provided on the side walls of the container.
  • FIGS. 8, 10 and 12 illustrate, the emptying of the collecting container 41, which has been brought into its folded-down position, is not impeded by the pendulum flap 49 forming the leak protection. Rather, due to the freely movable design of the flap 49 and its swivel axis provided above the tank bottom 45, it is advantageously possible to knock the tank bottom 45 by means of the flap 49 back and forth during the emptying process and thus also to knock the tank bottom 45 and thus also on the tank bottom or loosen dirt particles adhering to the side walls of the container and remove them safely.
