<p>The present invention relates to an agricultural spreader machine constituted by a chassis, a hopper and a unit which comprises a metering mechanism, a control mechanism and a spreader tube provided with a horizontal reciprocating motion. This machine is characterised in that, in order for the conversion of the rotational movement which is received by a wheel 15, by the intermediary of a drive shaft 18, into a reciprocating motion of a fork 13 coupled to a cone 8 for receiving the material to be spread coming from the hopper 1, there is provided, in the wheel 15, an elongated housing, with a radial axis of symmetry and, in this housing, a transverse spindle 16 which carries a lever 17 into which the tail 14 of the fork 13 penetrates, and the fork 13 is joined on, by its end parts, by means of two journals 23 carried by the cone 8, bearings incorporated in the end parts of the arms of the fork and stoppers 21 housed in the end parts of the arms of the fork 13. <IMAGE></p> |
