(54) | Rotary brush sweeper with easily separable debris pan |
(57) A rotary brush sweeper (10) includes a debris pan (22) with an inlet portion that
glides on a surface (100) being cleaned. The debris pan (22) automatically disengages
from the sweeper (10) upon being engaged by an obstacle in the path of the sweeper.
Rotary brooms (20) may be attached to the left and right front sides of the sweeper.
The support structure (58) for the front wheel (18) provides broom-to-ground height
adjustment for the side brooms (20). Additionally, brush-to-ground height adjustment
is obtained through a support structure (130) for the front wheel (18). The axle (55)
of the rotary brush (20) is held in place under the tension of a drive belt (56) for
the rotary brush (20). |
