<p>A slurry spreader (1), particularly for agricultural use, includes a fixed inner cylinder (3) and a coaxial outer cylinder (2) which is rotatable on the inner cylinder to bring holes (5, 6) in the cylinder walls into and out of register with each other. The inner cylinder (3) houses a screw conveyor (9) which rotates with the outer cylinder (2) to pump slurry along the inner cylinder from an inlet (4) and expel it through the holes (5, 6) when they are in register. Part-conical blades ( 12) mounted circumferentially on the outer cylinder (2) adjacent respective holes (5) therein cut through the soil as the spreader advances and push it aside to form open slits beneath the holes to receive slurry there from. <IMAGE></p> |
