Artificial fertiliser spreading machine - has oscillating member with outlets at different radii from vertical axis

摘要

The spreading machine is particularly for artificial fertiliser. It has a storage hopper with an outlet and a scattering member oscillating on a vertical axis, while metering devices are mounted between outlet and member. The member (4) is equipped with two or more passages (5,6,7) whose outlets are at different radii from the oscillation axis (A-A). The axes of the passages can be in the same vertical plane and each can have at the end plates holes affecting the scatter pattern.
