Definitions

  • the invention relates to a self-propelled sweeper with the features of the preamble of claim 1.
  • the outlet of the suction line and the at least one inlet region of the suction channel are arranged in the region of the front container wall of the dirt container. This allows the suction material entering via the outlet of the suction line to be thrown from the region of the front container wall to the rear container wall and thereby to obtain a particularly long separation distance, within which the suction air can separate from the sweeping material.
  • a rear line section of the intake passage passes through the suction channel. This allows a particularly compact design.
  • the suction line has a front line section which connects the suction mouth to a rear line section of the suction line, is oriented obliquely to the vertical and has a straight course.
  • the rectilinear course of the front pipe portion of the suction pipe reduces the flow resistance of the suction flow, so that the power consumption of the sweeper can be further reduced.
  • the straight course of the front pipe section with respect to the vertical oblique orientation also reduces the risk of clogging of the intake pipe.
  • the adapter is designed as a tank area in the form of a double-walled sleeve which rotatably receives the rear end of the front line section, wherein the rear end can be inserted without the use of a tool in the sleeve.
  • the rear line section of the suction line which passes through the suction channel, can adjoin the adapter.
  • the dirt container is preferably designed as a one-piece or multi-part plastic molded part, which is covered by one or more cover parts.
  • the dirt container in combination with the water tank and the suction unit forms an assembly in the form of a vehicle body, which can be placed on a footprint of the sweeper and detachable from this.
  • the footprint may for example be formed by support rails on which the vehicle body can be placed and along which the vehicle body is displaceable.
  • a self-propelled sweeper 10 is shown schematically with a chassis 12, which has a front in the direction of travel 13 frame member 14 and a rear frame member 16 in the direction of travel.
  • the two frame parts 14 and 16 are connected via a hinge 17 about a vertical pivot axis 18 pivotally connected to each other.
  • two steerable front wheels are rotatably mounted, in the drawing, only a front wheel 20 can be seen. Between the two front wheels, a suction mouth 22 is arranged.
  • At least one dish-shaped sweeping brush 24 is mounted on the front frame part 14, which can be rotated by means of a brush motor 25 about a nearly vertically oriented axis of rotation 26 in rotation.
  • a floor surface, such as a street, a walkway or a parking lot, swept, with the debris is fed to the suction mouth.
  • top-side receptacle 50 of the water tank 38 of the dirt container 36 dives with a container base 54, which is a one-piece plastic molding is formed and covered by a two-piece container shell 56.
  • the container top 56 is formed by a front container lid 58 and a rear container lid 60.
  • the front container lid 58 is detachably connected to the container base 54, in the illustrated embodiment, it is bolted to the container base 54.
  • the rear container lid 60 is hinged to the container base 54 and can be pivoted outwardly about a horizontal pivot axis 62 to release the container interior 64.
  • the container lower part 54 has a front container wall 66, a bottom wall 68 and a rear container wall 70 and two side walls 71, 72, based on the direction of travel.
  • a central portion of the front container wall 66 and the bottom wall 68 is covered on the inside by an arcuate channel wall 74 which, in combination with the covered portion of the front container walls 66 and the bottom wall 68, defines a central channel portion 73 of a suction channel 77.
  • central channel portion 73 To the central channel portion 73 is connected to the bottom wall 68 of the passage 53, which defines a rear channel portion 76 of the suction channel 77, and on the inside of the front container wall 66 connects to the central channel portion 73, a front channel portion 79 of the suction channel 77 at.
  • the central channel section 73 and the front channel section 79 of the suction channel are integrated into the dirt container 36 and are penetrated by a rear line section 78 of a suction line 80, which connects the suction mouth 22 with the container interior 64.
  • the rear pipe section 78 is formed by a pipe section 81 and a to the pipe section 81 subsequent manifold 88 formed.
  • the manifold 88 faces towards the corner region 90 of the container interior 64 between the rear container lid 60 and the rear container wall 70.
  • the suction conduit 80 comprises a rectilinear, obliquely oriented to the vertical front conduit section 82 in the form of a flexible a helically bent wire coil 84 reinforced suction hose 86th
  • the manifold 88 passes through the front channel section 79 of the suction channel 77 and forms with its mouth opening an outlet 89 of the suction line 80.
  • a respective inlet region 91 or 93 of the suction channel 77 is arranged laterally next to the outlet 89.
  • Another inlet region 95 of the suction channel 77 is located above the outlet 89. This will be off FIG. 3 clear.
  • the inlet regions 91, 93 and 95 are covered by a filter device in the form of a sieve 92, which is arranged between the container lower part 54 and the front container lid 58.
  • the entire vehicle body 34 can be removed from the support member 32 and placed on the support member 32 as needed. With the help of a locking device, the vehicle body 34 can be locked to the support member 32.
  • the water tank 38 is connected via a known per se and therefore not shown in the drawing to achieve a better overview water pipe with nozzles 108 in flow communication, which are held on the sweeping brush 24.
  • a water pump also not shown in the drawing, water can be pumped from the water tank 38 to the nozzles 108. Via the nozzles 108, the water can be sprayed onto the floor surface to be swept. As a result, when dusting a dust development can be kept low.
  • the container interior space 64 of the dirt container 36 is acted upon by the suction unit 40 with negative pressure.
  • the suction unit 40 is in fluid communication with the container interior 64 via the rear channel section 76 formed by the passage 53, the middle channel section 73 and the front channel section 79 of the suction channel 77.
  • the container interior 64 in turn is connected via the manifold 88 and the pipe section 81 of the rear pipe section 78 and the front pipe section 82 with the suction port 22 in flow communication.
  • a suction flow can be achieved to the dirt container 36 and from this via the suction channel 77 to the suction unit 40.
  • the suction air can be discharged from the suction unit 40 via a rear side held on the vehicle body 34 diffuser 110 to the environment.
  • the dirt container 36 is pivotally supported on the water tank 38. For emptying it can be tilted relative to the water tank 38 about a horizontal pivot axis 112 to the rear.
  • the skilled person known piston-cylinder units be used.
  • the rear line section 78 lifts off from the sleeve 102, which is formed by the water tank 38.
  • pivoting the dirt container 36 of the rear line section 78 again takes its voltage applied to the sleeve 102 position in which it is aligned with the front line section 82.
  • an effective suction flow can be achieved by means of the suction unit 40, so that debris from the suction mouth 22 and can be transferred to the dirt container 36.
  • the suction unit 40 may in this case have a relatively low energy consumption.
  • the sweeper 10 Due to the arrangement of the suction unit 40 below the dirt container 36 and the arrangement of the water tank 38 between the dirt container 36 and the suction unit 40, the sweeper 10 has a relatively low center of gravity. The risk that the sweeper tilts 10 on uneven ground can be kept very low.
