A debris-plowing pick-up head for a mobile sweeper comprises a housing defining a substantially hollow interior and having a front, a back, a left end and a right end, a top and a bottom, and a suctioning bottom opening for suctioning dust and small debris into the substantially hollow ulterior of the housing. A suctioning front opening is disposed in the front of the housing for receiving debris into the substantially hollow interior of the housing. A selectively openable and closable door means operatively mounted on the pick-up head for selectively opening and closing the suctioning front opening. There is a dust and debris outlet in the housing for permitting dust and debris to be suctioned from the substantially hollow interior of the housing into a hopper. There is also means disposed on the front of the housing for urging large debris toward the suctioning front opening, and a selectively operable actuation means for opening the door means for permitting the passage of debris therethrough. |
