Abstract
A snow removal device that picks up snow from the ground and flicks the snow into impeller units that transport the snow into a discharge tube whence the snow is expelled from the system. The system primarily includes a pick-up assembly, an impeller assembly, and a discharge tube. The pick-up assembly has a drum array that includes rows of triple-stepped blade-like fingers distributed evenly around each drum of the array of drums. These fingers are stiffly flexible and can cleanly and efficiently pick up snow from uneven ground surfaces and flick the snow into the impeller assembly that is mounted parallel to the axis of the drum array. The impeller assembly includes a plurality of impeller units that transport the snow into the discharge tube. The impeller units are reversible in direction, allowing the snow to be discharged to the right or the left of the system, or to the right and left simultaneously. The discharge tube and the impeller assembly lie in the same plane and are tilted upward approximately 20.degree. relative to the ground. Thus, the snow is discharged at a relatively low height to the ground. The discharge tube and impeller assembly can be pivotally attached to th…
