Apparatus for retrieving objects from the ground

摘要

An apparatus for collecting flat or semiflat materials while simultaneously retrieving bottles and cans includes a ground engageable rotating drum (50) with a plurality of fingers (80) extending radially from the drum. A spring finger assembly (100) cooperates with the drum (50) to retrieve articles from the ground. The spring finger assembly includes an upper and lower unit (104, 102) each including a plurality of spring fingers (128) mounted on a rotary shaft assembly (116, 118, 122) driven in conjunction with the rotation of the drum. The rotary shaft assembly and the spring fingers attached thereto rotate with respect to fixed stripper plates (140). A camming device (122, 130, 132) acts to rotate and extend the fingers beyond the stripper plates when the fingers move adjacent to the drum fingers and to rotate and withdraw the spring fingers behind the stripper plates upon further rotation such that the material engaged by the spring fingers is stripped therefrom.
