Exchangeable sweeping brush device and sweeper having such a sweeping brush device
First Claim
1. Exchangeable sweeping brush device for a carrier vehicle, comprising:
- a supporting frame; and
at least one sweeping brush which is rotationally drivable about an almost vertically oriented axis of rotation of the at least one sweeping brush and is held on the supporting frame,the supporting frame together with the at least one sweeping brush mounted thereon being detachably connectable to a supporting fork of the carrier vehicle,the supporting fork being mounted on a supporting part of the carrier vehicle, the supporting fork together with the supporting part being pivotable with respect to a chassis of the carrier vehicle about a first horizontal pivot axis oriented transversely to a longitudinal axis of the carrier vehicle;
the supporting frame comprising a first supporting assembly on which the at least one sweeping brush is mounted for rotation, and a second supporting assembly which is detachably connectable to the supporting fork;
the first supporting assembly being connected to the second supporting assembly for pivotal movement about a second horizontal pivot axis and being detachably connectable to the carrier vehicle by at least one tension member;
wherein;
the supporting fork comprises two substantially symmetrical prongs and a bridge part connecting the two prongs, the two prongs extending longitudinally and in spaced relation to one another parallel to the longitudinal axis, the bridge part being oriented transversely to the longitudinal axis,the bridge part is mounted on the supporting part for pivotal movement about a third pivot axis oriented transverse to the first horizontal pivot axis and the second horizontal pivot axis;
the second supporting assembly comprises a transverse member, which is detachably placed on and transversely spans between corresponding free end regions of the two prongs of the supporting fork, and on which the first supporting assembly is mounted for pivotal movement about the second horizontal pivot axis;
the transverse member comprises two receptacles each of which directly receives one of the corresponding free end regions of the two prongs of the supporting fork;
the first supporting assembly is pivotable about the second horizontal pivot axis against a spring-elastic restoring force;
a strength of the spring-elastic restoring force is adjustable; and
the spring-elastic restoring force is applied by a spring element which is clamped between the first supporting assembly and the second supporting assembly.

Abstract
An exchangeable sweeping brush device for a carrier vehicle is provided. The device has at least one sweeping brush which is rotationally drivable about an almost vertically oriented axis of rotation of the brush and is held on a supporting frame, the supporting frame being detachably connectable to a supporting fork of the carrier vehicle, which is pivotable about a first horizontal pivot axis oriented transversely to the longitudinal axis of the vehicle. The supporting frame comprises a first supporting assembly on which the at least one sweeping brush is rotatably mounted, and a second supporting assembly which is detachably connectable to the supporting fork, the first supporting assembly being connected to the second supporting assembly for pivotal movement about a second horizontal pivot axis and being detachably connectable to the carrier vehicle by at least one tension member. A sweeper having such a sweeping brush device is also proposed.
