A turf sweeper includes a hopper mounted on a frame. A debris loading duct mounted on the frame includes an intake opening supported in closely spaced relation above the ground and a discharge opening at a discharge end communicating with a hopper inlet. A broom is rotatably mounted within an intake section of the debris loading duct proximate and across the intake opening. A paddle rotor, having a plurality of paddles outwardly projecting paddles is rotatably mounted within and across a transfer section of the debris loading duct with a path of rotation of tips of the paddles extending in closely spaced relation to a path of rotation of tips of the pick-up members of the pick-up head. A return air duct flow connects a return air outlet to the hopper with a return air opening through the transfer section of the debris loading duct. 1. A sweeper moveable over the ground to collect debris on the ground comprising:a hopper having a hopper inlet opening;a debris loading duct having an intake opening at an intake end supported in closely spaced relation above the ground over which the sweeper is moved and a discharge opening at a discharge end of the debris loading duct, the debris loading duct flow connected to the hopper such that the discharge end of the debris loading duct is aligned with the hopper inlet opening and the discharge opening communicates with the hopper inlet openinga rotary pick-up head, having a plurality of pick-up members projecting radially outward from a pick-up head axle and rotatably mounted within an intake section of the debris loading duct proximate the intake opening, the rotary pick-up head extending across the debris loading duct such that upon rotation of the rotary pick-up head the pick-up members are positioned to contact and lift debris from the ground into the debris loading duct;a paddle rotor, having a plurality of paddles projecting radially outward from a paddle axle and rotatably mounted within and across a transfer section of ...

Turf maintenance implement with releasable tool housing for interchangeable rotary tools

Номер: US20240263411A1
Автор: Adam P. Meng, Casey A. Leis
Принадлежит: Harper Industries Inc

A turf maintenance implement for collecting landscape debris from the ground includes a frame, a hopper assembly mounted to the frame, a debris loading duct, a rotary tool housing, and a drive assembly. The debris loading duct is connected to the frame and is in communication with the hopper assembly. The debris loading duct includes a first latch portion of at least one manually operable latch mechanism connected thereto. The rotary tool housing includes a rotary tool rotatably mounted thereto, and a second latch portion of the at least one manually operable latch mechanism connected thereto. The rotary tool housing is selectively detachable from the debris loading duct by releasing the first latch portion of the at least one manually operable latch mechanism from the at least one second latch portion. The drive assembly is connectable to a power source and drivingly and releasably connected to the rotary tool.
