Abstract
An air seeder venting system comprising a filter screen mounted in a distribution head of an air seeder for separating seeds from air fed from a supply conduit, the distribution head having an inlet in communication with the supply conduit, a plurality of seed outlets in communication with seeding lines, and an air exhaust, wherein the filter screen is located so as to have at an upstream side the inlet and the plurality of seed outlets, and at a downstream side the air exhaust.

An air seeder venting system comprising a filter screen mounted in a distribution head of an air seeder for separating seeds from air fed from a supply conduit, the distribution head having an inlet in communication with the supply conduit, a plurality of seed outlets in communication with seeding lines, and an air exhaust, wherein the filter screen is located so as to have at an upstream side the inlet and the plurality of seed outlets, and at a downstream side the air exhaust.
A filter screen for an air seeder distribution head for separating seeds from air fed from a supply conduit to the air seeder distribution head, wherein the filter screen is conical.
A method of fitting a venting system to an air seeder, including the steps of:
- providing a distribution head of the air seeder with an air exhaust, and
- mounting a filter screen in the distribution head of the air seeder for separating seeds from air fed from a supply conduit, the filter screen being located so as to have at an upstream side an inlet of the distribution head in communication with the supply conduit and a plurality of seed outlets of the distribution head in communication with seeding lines, and at a downstream side the air exhaust of the distribution head,
- wherein the filter screen is adapted such that in use air from the inlet passes through the filter screen to the air exhaust, and seeds carried by the air are arrested by the filter screen and deflected by the filter screen to fall by gravity through the plurality of seed outlets.
