ABSTRACT:
A surface cleaning machine (10) is disclosed in the preferred form as a combination sweeping-scrubbing apparatus including a sweeping brush (18) for sweeping debris into a hopper (20) and a one piece squeegee (112) for picking up solution after four staggered, disc brushes (122). The squeegee (112) is U-shaped having a longitudinal extent greater than that of the disc brushes (122) located intermediate the legs (124) of the squeegee (112). The drive wheel (16) is located in front of the disc brushes (122), the squeegee (112) and the solution applying means (128). The squeegee (12) is raised and lowered relative to the frame (12) by an actuator (104) which pivots an L-shaped member (94), the leg (96) of which abuts against and pivots a lever (84) interconnected to the mount (62) for the squeegee (112) by a turnbuckle (88). The hopper (20) is raised and simultaneously tilted by a single cylinder (30 ) which pivots the upper arm (24) of a parallelogram including a lower arm (36). The hopper (20) is pivotally mounted to an end of a hopper arm (48), the opposite end of which is pivotally mounted to the end of the upper arm (24), and is further pivotally mounted to the end of the lower arm (36). The hopper (20) is simultaneously tilted at a generally constant dump angle as the hopper (20) is raised from a lowered position in a horizontal debris collecting condition to a raised position with the hopper (20) in a dumping condition.
