Abstract
A driving unit supported by a frame for an oscillating spreading pipe of a device for distributing material, for example, fertilizer, said unit mainly comprising a drivable fly-wheel, a holder for the spreading pipe to be oscillated by the fly-wheel through a coupling element eccentrically journalled in said fly-wheel and a dosing mechanism arranged above said holder, wherein a part of the frame thereof extends in dish-shaped fashion on either side of the driving unit, said dish-shaped frame portion not only serves as a protective member during transport, but also operates as a stiffening part.
Claims11
A driving unit supported by a frame for the oscillating distributing pipe of a device for spreading material, for example, fertilizer, said unit mainly comprising a drivable fly-wheel, a distirbuting-pipe holder to be oscillated by the fly-wheel through a coupling element eccentrically journalled in said fly-wheel and a dosing mechanism arranged above said holder, characterized in that a portion of the frame extends in a dish-shaped fashion on either side of the driving unit, said dish-shaped portion having an opening receiving and locating said dosing mechanism.
A material spreading unit comprising a frame adapted to be driven by a power take-off shaft of a powered vehicle, said frame having a substantially horizontal first boss at its forward end and an upright second boss at its rearward end, a shaft journalled in said first boss and having at its forward end means adapted for driving connection with a power take-off shaft of a vehicle, a flywheel connected to said shaft rearwardly of said first boss, a spindle rotatably received in said second boss and projecting upwardly therefrom, a holder connected to said spindle above said second boss, drive means coupling said holder to said flywheel for oscillating said holder and spindle as the flywheel rotates, distributing means connected to said holder for broadcasting material such as fertilizer, said distributor means comprising a material-receiving member surrounding said spindle and having an upwardly facing inlet, and a distributor pipe communicating with said material-receiving member and projecting substantially horizontally and rearwardly therefrom whereby to whip back and forth as the holder oscillates and fling the material from the rearward end of the distributor pipe, a rigidifying frame in the form of an inverted, dish-shaped housing attached at its lower, open side to said frame and extending in covering relation to said first and second bosses as well as the flywheel, the drive means, the holder, the drive means and said material-receiving member, and a dosing assembly carried by said housing in vertical registry with said inlet of the material-receiving member.
