The disclosure relates to a protective and levelling device for use in a distributor which is primarily intended for commercial fertilizer, the distributor having a spreader device which rotates in a horizontal plane and ejects the material to be distributed radially or tangentially in this plane. The protective and levelling device comprises a deflector plate which is located in the path of the flow of material originating from the spreader device, between the spreader device and the distributor machine proper. Moreover, in its capacity as impingement surface for the flow of material, the deflector plate has a convex curved surface, whereby that portion of the flow of material which impinges on the convex surface will rebound from the surface and be distributed. |
