Definitions

  • the present invention relates to a sweeping machine with a chassis for moving the sweeping machine over a surface to be cleaned, with a mounted on the chassis, rotatably driven sweeping roller, which is surrounded by a sweeping roller housing, wherein the sweeping roller along its axis of rotation between a first and a second side wall of the sweeping roller housing, with a suction device which is connected on the intake side for sucking dust-laden air with the sweeping roller housing, and with a mounted on the chassis, rotationally driven side brush.
  • sweeping machines From the state of the art like the DE 197 15 435 C2 known sweeping machines have a chassis with which the machine can be moved over a surface to be cleaned such as threads, roads, squares and the like.
  • the landing gear has a powered sweeping device with bristles that move across the surface.
  • a sweeping device is formed as a sweeping roller extending transversely to the direction of travel parallel to the surface, which is driven in rotation.
  • the sweeping roller is surrounded by a sweeping roller housing, which communicates with a suction device in connection to suck the dust raised by the sweeping roller.
  • sweeping roller sweepers In addition to the mounted on the chassis, extending over the width and transverse to the direction sweeping roller sweepers are often still provided with a side mounted on the chassis side brush, with the edge regions of the surfaces to be cleaned, which are not covered by the sweeping roller, for example, curbs cleaned can be.
  • Spray nozzles are mainly used in outdoor cleaning, while in the interior cleaning area, however, there is often the requirement that the surface to be cleaned should remain dry. For higher demands on the air quality in closed rooms partial enclosures are therefore used.
  • the present invention therefore relates to dry-working, mechanically-receiving sweepers with a side brush.
  • the side brush is surrounded by an enclosure, that a connecting line between the sweeping roller housing and the housing is provided and that a connection of the connecting line is provided to the sweeping roller housing in one of the side walls.
  • the sweeping roller possibly by radially extending bristle elements, the effect of a radial fan, ie an air flow radially outward Shen and thus a negative pressure in the region of the end surfaces of the sweeping rollers or in the forehead area is generated.
  • this effect can be achieved when the bristles are arranged in mutually circumferentially spaced strips which are parallel to the longitudinal axis of the sweeping roller or inclined thereto axially, the strips have sections with divergent, ie changing slope can.
  • connection of the connecting line to the sweeping roller housing in the region of the side wall is adjacent to one end of the sweeping roller, the negative pressure generated by the rotating sweeping roller can be exploited to the additional air flow for the extraction of air from the enclosure of the side brush to create. In this way, it is not necessary to provide a larger-sized suction on the sweeping machine.
  • a sweeper is to be additionally provided with a side brush, only a small structural effort for the dust extraction on the side brush is required. It is only necessary that the connection is made in the sidewall of the sweeping roller housing.
  • the dismantling can also be done in a simple manner by removing the connecting line and closing the connection, without the suction of the sweeping roller must be changed.
  • the port on the side wall intersects with an end surface projection onto the sidewall parallel to the axis of rotation.
  • the sweeping roller has bristles extending radially away from a central body which extends along the axis of rotation.
  • the terminal on the side wall may be disposed immediately adjacent to the projection of an end face of the center body on the side wall or overlapping, then preferably only partially overlapping. This then ensures that the connection is arranged adjacent to the radially innermost portion of the bristles, in which there is the greatest negative pressure, so that in a particularly effective manner, an air flow in the connecting line can be generated.
  • the side brush is rotatably driven about an inclined surface to be cleaned, preferably at an angle between 75 ° and 90 °, extending axis of rotation, wherein the connecting line is attached to a wall portion of the housing, through which the axis of rotation extends.
  • the suction device of the sweeping machine can have a fan, wherein a filter is arranged between the fan and the sweeping roller housing.
  • FIGS. 1 and 2 show the embodiment of a sweeping machine according to the invention, this is designed here as a ride-on machine and has a chassis 1 with wheels 3, so that the sweeper with the seated user can drive over a surface to be cleaned 5 such as a walkway, a street or a place.
  • the sweeping machine is designed in such a way that a user runs behind the machine ago, so that the invention is not limited to Aufsitzmaschinen.
  • the sweeping machine comprises a rotary driven sweeping roller 7 with a cylindrical shape, which is mounted on the chassis 1 and extends parallel to the surface 5 and substantially perpendicular to a main movement direction 9, along which the sweeping machine moved by means of the chassis 1.
  • the broom 7 is in contact with the surface 5, so that due to the rotation of the broom 7 on the surface 5 befind another dirt is raised.
  • the sweeping roller 7 is formed in such a way that it has a central body 11 which extends along the axis of rotation 13 and are attached to the bristles 15 extending radially to the axis of rotation 13.
  • the bristles 15 may be in each other in the circumferential direction of the sweeping roller. 7 spaced strips are arranged, which extend parallel to the axis of rotation 13 of the sweeping roller 7 or inclined thereto axially, wherein the strips sections with divergent, ie changing inclination to the axis of rotation 13, may have.
  • the sweeping roller 7 preferably has radially extending from the axis of rotation 13 elements.
  • the sweeping roller 7 is surrounded by a sweeping roller housing 17, which also has a receiving area 19 for coarse dirt and a suction device 21 in the rear part.
  • the suction device 21 comprises a fan 23, the suction side of a filter 25 is connected upstream, so that the filter 25 is located between the fan 23 and the sweeping roller housing 17 and the suction device 21 is connected to the suction side for sucking dusty air with the sweeping roller housing 17. Accordingly, an air flow in the sweeping roller housing 17 can be generated by the sweeping roller 7 towards a pressure side of the fan 23 with the aid of the suction device 21.
  • Fig. 4 shows the sweeping roller 7 between a first side wall 27 and a second side wall 29 of the brush roller housing 17.
  • a first end face 31 which extends perpendicular to the axis of rotation 13 to the first side wall 27, while a second, also perpendicular to Fulcrum 13 extending end surface 33 to the second side wall 29 has.
  • the outer periphery of the sweeping roller 7 defines a projection 35 parallel to the axis of rotation 13 on the first side wall and in an analogous manner, the outer periphery of the central body 11 of the sweeping roller 7 also defines a projection 37 parallel to the axis of rotation 13 on the first side wall 27.
  • the outer edges of this Projections 35, 37 are each in FIG. 4 characterized.
  • the embodiment of the sweeping machine is provided with a side brush assembly 39 which has a side brush 41 which is about an axis of rotation 43, which in this preferred embodiment at an angle between 75 ° and 90 ° to the surface to be cleaned 5 runs, is driven in rotation and whose bristles point to the surface 5 to be cleaned. Furthermore, the side brush assembly 39 has an enclosure 45 which substantially completely surrounds the side brush 41 and is open only to the surface 5. The side broom assembly 39 serves to clean peripheral areas of the surface 5 which can not be reached by the sweeping roller 7, such as areas adjacent to curbs.
  • the housing 45 of the side brush assembly 39 is connected via a connecting line 47 with the sweeping roller housing 17.
  • one end of the connecting line 47 is connected to a wall portion 49 of the housing 45, through which the axis of rotation 43 extends and which here extends substantially perpendicular to the axis of rotation 43 of the side brush 41.
  • the housing-side end of the connecting line 47 has a connection 51 which lies within the projection 35 parallel to the axis of rotation 13 of the first end face 31 of the sweeping roller 7 on the first side wall 27 (see Fig. 4 ) so that the connection 51 overlaps with the projection 35 of the end face 31 of the sweeping roller 7 on the first side wall 27 parallel to the rotation axis 13. While in the arrangement according to Fig.
  • the terminal 51 is disposed immediately adjacent to the projection 37 of the end face of the center body 11, overlaps in the arrangement according to FIG Fig. 4
  • the connection 51 is in the radial direction of the sweeping roller 7 in the region of the inner ends of the bristles 15 of the sweeping roller 7 and is thus spaced from the center the projections 35, 37 arranged on the first side wall 27.
  • both the sweeping roller 7 and the side brush 41 are driven in rotation.
  • the fan 23 is in operation, so that air is drawn from the bottom surface 5 facing the opening 53 of the sweeping roller housing 17 through the filter 25 and discharged to the outside. From the sweeping roller 7 and the bristles 15 thrown dirt reaches the interior of the brush roller housing 17, wherein coarse dirt is deposited in the receptacle 19, while particulate matter catches in the filter 25.
  • this also acts as a radial fan, in which a negative pressure is formed adjacent to the rotation axis 13 or on the outer circumferential wall of the central body 11, since air is conveyed radially outward by the bristles 15. Due to the arrangement of the terminal 51 of the connecting line 47 just adjacent to the projection 37 of the central body 11 on the first side wall 27 of this negative pressure generated by the sweeping roller 7 leads to an air flow through the connecting line 47 away from the housing 45 of the side brush 41. Due to this air flow For example, dust thrown up by the side brush 41 is drawn into the brush roller housing 17 through the connection pipe 47, and the dust is prevented from leaving the housing 45 to the outside.
