Definitions

  • the invention relates to a sweeper with at least one removable feed brush, which is mounted on a front corner region of a housing on a cantilever arm for feeding sweepings to a sweeping roller.
  • Sweepers of this type are used in particular for cleaning larger courtyard or hall areas, the sweepings being picked up by means of one or more sweeping rollers and being conveyed into a collecting basket. Work performance of several hundred square meters is possible in a force-saving manner, since the sweeper is easily pushed over the surface to be swept with an approximately 80 cm wide sweeper roller.
  • one or two rotating feed brushes are provided at the front corner area of the sweeper housing, which surrounds the top of the sweeping roller and stores the grass catcher so that the dirt in the baseboard area or in the corner area along walls or curbs is also included is picked up because these rotating side brushes convey the dirt towards the center and thus towards the roller brush.
  • DE-GM 94 03 678 of the applicant has proposed that a removable end cap is mounted on the cantilever arm provided on the front corner region of the housing.
  • the feed brush can be easily removed, which considerably reduces the cantilever length of the cantilever arm and thus the sweeper in can be packed in a transport box with a smaller footprint.
  • the object of the invention is to create a sweeper which enables a rapid changeover between an operating position and a non-operating position of the feed brush in a particularly simple and safe manner.
  • the drive pinion is mounted on the axle bearing housing for the brush axis of the feed brush, so that no additional effort is required from the manufacturing effort.
  • the preferred design of the drive pinion with a greater axial length than the overall height of the gear in connection with the height-adjustable brush axis ensures that even with a larger height adjustment stroke the feed brush always has constant engagement conditions and thus a safe drive, since the drive belt and the drive pinion itself with the feed brush removed, remains as a structural unit in the boom arm of the sweeper.
  • a sweeper 1 which has at least one sweeping roller 2, which picks up the sweeping material lying on the floor and conveys it into a grass catcher 3.
  • the grass catcher is here by means of a grass catcher frame 3a mounted on a housing 4 at least partially surrounding the sweeping roller 2.
  • a handle bracket 5 which extends obliquely upward at approximately 30 ° for pushing the sweeper.
  • two lateral pivot bearings 6 are provided, which serve to adjust the inclination of the handle 5.
  • one or two feed brushes 7 are provided, which combine the sweepings in the lateral direction and feed the sweeping roller 2.
  • the sweeping roller (s) is / are supported and driven at the same time via wheels 8 arranged on the side of the housing 4.
  • the front corner area with the feed brush 7 is shown enlarged in longitudinal section, the feed brush 7 being supported by a cantilever arm 9 projecting from the housing 4.
  • the feed brush 7 has an upright brush axis 10 which is mounted displaceably in the vertical direction. This is done here by means of an axle bearing housing 13 in which the brush axis 10 is fitted with a clearance fit and can thus be moved in the upright direction.
  • a compression spring 14 arranged within the axle bearing housing 13, the brush body of the feed brush 7 is completely or at least largely lifted off the bottom surface in the inoperative position. In the deeper, dashed working position, however, the brush axis 10 protrudes downward from the plate-shaped axle bearing housing 13 so that the feed brush 7 rests almost completely on the floor surface with a certain pressure.
  • the feed brush 7 has a gearwheel 11 above the brush body, which meshes with a drive pinion 11a mounted in the extension arm 9 in order to drive the feed brush 7 by means of a belt 12 derived from the drive of the sweeping roller 2.
  • the gear 11 is attached to the brush axis 10 in the same axis as the feed brush 7, the gear 11 also being integral with the holder body for the Bristles of the feed brush 7 can be formed.
  • the drive pinion 11a which meshes with the gear 11 in the working position shown here is mounted on the axle bearing housing 13 for the brush axis 10 of the feed brush 7 by means of an axle bolt 11c.
  • the axle bearing housing 13 can preferably be designed as an injection molded part and can be detachably fastened to the underside of the cantilever arm 9 by means of a plurality of bushings 13a (cf. also FIG. 3).
  • an axially identical pulley 11b is preferably provided in one piece with it, as an injection molded part, around which the belt 12 guided by the drive of the sweeping roller 2 is placed and thus preassembled in the production plant.
  • This belt 12 is driven by a drive pulley 12a, which in turn is driven by a drive wheel 8a interacting with one of the side wheels 8 (cf. also FIG. 3).
  • a different type of drive (such as a belt or chain drive) can be selected for the drive pinion 11a.
  • a locking device 15 In order to fix the feed brush 7 in one of the two positions, namely the higher relief position or in the lower working position, a locking device 15, indicated only schematically by hatching, is provided in FIG. 2, which fixes and clamps the brush axis 10 in the respective position.
  • the locking device 15 is formed by a lever or bracket encompassing the brush axis 10 in a U-shape, which is biased by a spring. As a result, the brush axis 10 is fixed in its height position.
  • a hemispherical push button 19 is provided at the upper end of the brush axis 10, which can also be pressed with the foot, in order to move the feed roller 7 from the higher relief position according to FIG. 2 into the lower working position to move down. It should be pointed out that with this sliding movement from top to bottom the locking device 15 is not self-locking, but rather enables the sliding movement of the brush axis 10 downwards. Here too, the toothing of the gearwheel 11 slides along the drive pinion 11a while maintaining the toothing engagement.
  • the respective height of the working position can be set with a height stop 20 shown in FIG. 2, which is formed here from a rotary knob 22 mounted in the extension arm 9 and having step-shaped steps 21 on the outer circumference.
  • the feed brush 7 can only be adjusted downward by exerting pressure on the push button 19 until the underside of the push button 19 abuts the step 21 on the left here.
  • the right step 21 or an intermediate step can be brought into line with the lower right edge of the push button 19 here by turning the rotary knob 22, so that the brush axis 10 can be adjusted further downward.
  • this height stop 20 can also be used to adjust the contact force and thus the sweeping intensity of the side brushes.
  • FIG. 3 shows a bottom view of the cantilever arm 9 along the section plane X in FIG. 2.
  • the remaining reference numerals correspond to the components described above.
  • the assembly is carried out by the gear transmission 11 / 11a and the remaining belt 12 (i.e. no longer to be put on each time the feed brush 7 is removed) in a simple, quick and safe manner.
  • the brush axis 10 can also be inserted into the extension arm 9 from below instead of through the lateral slot 23 or removed by pulling it downward.
