900,563. Fertilizer distributers. RAUSCH, M. Nov. 24, 1960 [Dec. 8, 1959], No. 40372/60. Class 6(1). A manure distributer comprises a centrifugal ejecter disc 1 coupled to a top plate 3 and both provided with projector ribs 2, 4 respectively which may extend completely between the disc 1 and plate 3. The disc and plate rotate between a top deflector ring 6 and a bottom deflector ring 7 which slope more steeply at the front and rear than at the two sides. The ribs, 2, 4 act as a fan and the rings 6, 7 deflect material downwardly. The rings 6, 7 may be made of rigid sheet metal or flexible polyvinylchloride sheet. To vary the distribution pattern of material deposited the rings 6, 7 may be removed. The density of distribution may be altered by adjusting the height of the disc 1 and plate 3 in relation to the rings 6, 7. A wind shield or baffle shaped to correspond to the shape of the distribution area may be provided. Such a shield may be provided at the outer ends with supporting wheels or skids which can be used as track markers. |
