ABSTRACT:
The invention relates to a device for spreading distributable material, for example, fertilizer, comprising a hopper for the material having a delivery port and a reciprocatorily, swinging pipe-shaped distributor joining said delivery port, more particularly a fertilizer distributor pipe; in practice it has been found that the inner wall of the pipe of a device of the kind set forth is subject to heavy wear due to the heavy frictional forces between the material to be distributed and the inner wall; the invention has for its object to provide a more wear-resistant pipe and provides for this purpose a device comprising a distributor pipe adapted to swing to and fro, in which the inner wall of the pipe is coated with a wear-resistant layer within a region extending from the outlet end to the substantially upright wall portions.
