The hopper of a fertiliser spreader is divided into separate compartments (5a) and (5b) which are essentially flat except for cylindrical recesses (14a), (14b). Outlet holes (7a) and (7b) are located on the side of each recess which is closest to the partition plate (10). A funnel (27) is connected below both outlet holes (7a) and (7b) and has its central axis in the same plane as the partition (10). The bottom of the funnel is arranged to be connected with an outlet hose which is not shown. Regulator plates (26a), (26b) are shown extending diagonally from the rigid section of the partition plate down over recesses (14a), (14b) and extend between the side walls of each compartment. Fertiliser discs are arranged to be placed on axles (15a) and (15b) respectively above low-friction discs (not shown). The fertiliser discs have internal or external castilations in order to regulate the discharge of fertiliser from the hopper. The axles (15a) and (15b) are supported by bearings (16a), (16b) respectively and are driven by a main shaft through a bevel gear coupling (17a). Fertiliser in each compartment is moved by one of the augers provided therein over a respective fertiliser disc which by virtue of its rotation directs the fertiliser to a corresponding outlet hole (7a) or (7b). The fertiliser then passes into the funnel and out through the outlet hose. |
