Definitions

  • the present invention relates to a circular broom, a sweeping device and a floor cleaning machine.
  • Disc brooms are known from the prior art. For example, circular brooms are used in sweeping devices of floor cleaning machines, whereby they are driven in rotation in order to convey debris on a floor surface to be cleaned with their bristles in the direction of a receiving device of the floor cleaning machine, so that the receiving device can pick up the debris from the floor surface to be cleaned.
  • the rotating disc brushes move the bristles of the disc brush around its axis of rotation.
  • the movement of the bristles about the axis of rotation in turn ensures an air flow into the area of the bristles and then radially away from the bristles, so that the debris can be whirled up before it can be picked up by the receiving device.
  • the debris has a high proportion of dust
  • whirling up the debris leads to dust being whirled up, which can float in the air for a comparatively long time and spread over a wide area.
  • blown dust should be avoided when transporting debris.
  • a circular broom with the features of claim 1.
  • the circular broom is adapted to be connected to a rotary drive to form a sweeping device.
  • the circular broom has a base body.
  • the base body can be coupled to the rotary drive for rotation about an axis of rotation and has a circumferential outer edge.
  • the circular broom has bristles, one end of which is attached to the base body and which extend away from the base body and towards a sweeping plane extending perpendicular to the axis of rotation.
  • the circular broom has a cover element.
  • the cover element has a preferably conical shell made of a flexible material, which extends from the base body, preferably from the Outer edge, extends away and towards the sweeping plane.
  • the shell has an inner side that faces an interior of the shell.
  • the shell has an outside that faces an exterior of the shell.
  • the sheath envelops the bristles perpendicular to the axis of rotation such that the bristles are arranged in the interior of the sheath.
  • the base body can be coupled to the rotary drive for rotation about an axis of rotation.
  • the rotary drive can drive the base body so that the base body rotates around the axis of rotation.
  • the base body can have a coupling means for coupling to the rotary drive.
  • the coupling means of the base body can have a recess and a circumferential contact surface.
  • the circular broom has bristles, one end of which is attached to the base body and which extend away from the base body and towards a sweeping plane extending perpendicular to the axis of rotation.
  • at least one part of the bristles which is outer radially relative to the axis of rotation runs inclined to the axis of rotation, so that the free ends of the part of the bristles are at a greater distance from the axis of rotation than the ends which are attached to the base body.
  • the attachment of the bristles with one end to the main body ensures that the bristles move about the axis of rotation when the main body rotates about the axis of rotation.
  • the movement of the bristles about the axis of rotation enables the bristles, when they engage with a floor surface to be cleaned, to convey debris along the floor surface to be cleaned.
  • the extension of the bristles away from the main body and towards the sweeping plane running perpendicular to the axis of rotation ensures that the free ends of the bristles removed from the main body engage with the floor surface to be cleaned and thus can convey debris along the floor surface to be cleaned.
  • the circular broom has a cover element with a preferably conical sheath, the sheath surrounding the bristles. If at least the radially outer part of the bristles extends in an inclined or conical manner away from the base body and towards the turning plane, the conical casing is adapted to the course of the bristles.
  • the preferably conical shell is formed from a flexible material.
  • the flexibility of the material of the envelope ensures elastic deformation of the envelope large deformation areas, so that the shell assumes its original shape again even after severe deformations.
  • the flexibility of the material of the cover enables a section of the cover element to rest flat on the floor surface when it engages the floor surface to be cleaned, so that debris can be conveyed particularly thoroughly along the floor surface to be cleaned by a surface friction force.
  • the flexibility of the material of the cover can ensure that the cover deforms elastically if the cover hits an obstacle as it moves over the floor surface to be cleaned.
  • An obstacle can, for example, be a wall that limits the floor area to be cleaned or a shelf that extends over the floor area to be cleaned. The elastic deformability of the shell can thus increase the service life of the shell.
  • the shell extends away from the main body and towards the turning plane.
  • the extension of the sheath away from the base body and towards the inverting plane enables the bristles to be sheathed around the axis of rotation.
  • the shell can extend away from the outer edge of the main body.
  • the shell can rest against the base body, so that when the base body rotates about the axis of rotation, due to frictional forces that can act between the shell and the base body, the cover also rotates about the axis of rotation.
  • the shell can rest against the base body and be fastened to it, so that when the base body rotates, the cover rotates together with the base body about the axis of rotation.
  • the shell has an inside and an outside.
  • the inside faces an inside of the shell and the outside faces an outside of the shell.
  • the shell can separate the interior of the shell from the exterior of the shell.
  • the sheath envelops the bristles perpendicular to the axis of rotation such that the bristles are arranged in the interior of the sheath.
  • the sheathing of the bristles perpendicular to the axis of rotation by the sheath, so that the bristles are arranged in the interior of the sheath can minimize air currents towards and away from the bristles.
  • the Envelope reduces air currents between the interior of the envelope and the exterior of the envelope. The swirling up of debris before it can be picked up by the pick-up device is also minimized by reducing the air currents.
  • the casing prevents an air flow from entering the area of the bristles and the air being accelerated again radially out of the area of the bristles as a result of the rotation of the circular brush. Because such a flow is prevented, the disc broom according to the invention results in a significantly lower amount of dust whirling up during operation than brooms according to the prior art.
  • the circular broom can reliably convey debris and that dust that is blown up is avoided or at least the amount of dust that is blown up is kept low.
  • the base body has a top side that faces away from the interior of the shell and a bottom side that faces the interior of the shell, wherein, when the base body is coupled to the rotary drive, between the interior of the shell and the top side of the base body there is no fluid connection through the base body.
  • the free ends of the bristles that are remote from the base body are arranged in the inverting plane.
  • the arrangement of the free ends of the bristles remote from the main body in the sweeping plane enables the free ends of the bristles to move around the axis of rotation in the sweeping plane. Moving the free ends of the bristles around the axis of rotation in the sweeping plane enables the free ends of the bristles to engage precisely with the floor surface to be cleaned.
  • a circumferential envelope section of the envelope with the axis of rotation forms an envelope angle of at least 5 and at most 85 degrees, preferably at least 20 and at most 70 degrees, particularly preferably at least 35 and at most 55 degrees.
  • An envelope angle of at least 5 degrees ensures that when a portion of the cover element engages the floor surface to be cleaned, the envelope portion will deformed away from the axis of rotation and towards the exterior of the envelope. This effect increases with increasing envelope angle.
  • An envelope angle of at most 85 degrees ensures that the bristles are enveloped by the envelope around the axis of rotation, even if the envelope is elastically deformed. If the envelope angle is further reduced, the bristles can be enveloped by the envelope around the axis of rotation, even in the case of larger elastic deformations of the envelope.
  • the flexible material is formed from a natural rubber.
  • Natural rubber is a particularly flexible and wear-resistant material.
  • the flexible material can be formed entirely or at least partially from natural rubber.
  • the natural rubber can be vulcanized.
  • a vulcanized natural rubber provides an almost purely elastic deformation behavior over wide deformation ranges.
  • the flexible material can be formed from Linatex. Linatex has proven to be particularly advantageous when used as a flexible material for the conical casing. When using Linatex, the cover has optimal flexibility and durability with a high sweeping effect.
  • the present invention is not limited to the fact that the flexible material is formed from a natural rubber.
  • the flexible material can also be formed entirely or at least partially from a synthetic rubber.
  • the present invention is not limited to the flexible material being formed from a natural rubber or a synthetic rubber.

If the flexible material is an elastomer, a glass transition temperature of at most 0 ° C ensures that the flexible material is used in the rubber-elastic range at temperatures above 0 ° C. It is particularly advantageous if the flexible material has a glass transition temperature of at most -30 ° C., since this allows the casing to be elastically deformed, even if the circular broom is used outside in severe frost.
  • the flexible material has a modulus of elasticity of at most 5 GPa.
  • a modulus of elasticity of at most 5 GPa ensures that the shell has a low resistance to elastic deformation, so that the shell is Contact with an obstacle is deformed and the shell and the obstacle are not plastically deformed.
  • the shell is designed as a closed surface, so that there is no fluid connection through the shell between the exterior of the shell and the interior of the shell.
