Pneumatic spreading machine for e.g. seed, has distributor lines attached at circle-symmetrically distributed arranged outlets of distributor head, and wedges pointing to center of head with their vertex provided with guide at its base
The machine has a dosing body for supplying seeds and fertilizer to a pneumatic conveyor pipe. Distributor lines (5) are attached at circle-symmetrically distributed arranged outlets (4) of a distributor head, and locking wedges (6) cooperating with the outlets are provided for locking the individual lines. The wedges pointing to the center of the head with their vertex have a guide at its base opposite to the vertex, where the wedges are clamped force-fit into the guide. The wedges are made of thermosetting polymer, elastic material e.g. elastomer, and plutonium-casting resin.
