The apparatus described is a spiro conveyor of a special design, used chiefly for the titration and the spreading out of granular material, having a housing provided with an input and an output hopper, in which housing is mounted a rotary shaft carrying a screw. The invention is characterized in that the screw (3), arranged as an elastic element, is fixed to the shaft (2) in such a way that its pitch can be varried at least near the input hopper (5). According to the described solution, a granular material, such as agricultural materials can be fed and spread out with a continuous setting by means of a simple apparatus. |
