Abstract
Abstract ABSTRACT OF THE DISCLOSURE An airflow particulate material transfer arrange-ment for use with an airflow seeder in which a primary conduit has included subsequent to a particulate material inlet and before a first primary distribution location, a plurality of vanes to assist, firstly, to keep particulate material airlifted within the airflow and uniformly distributed and secondly adjust-able vanes to assist in providing final adjustment of uniformly proportioning particulate materials being driven in to each of the secondary conduits. Advantage is also found in keeping the primary conduit from a fan to the primary distribution location of substantially constant cross-sectional area except in the vicinity of the particulate material inlet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
An airflow particulate material transfer arrange-ment for an airflow seeder of a type including a bulk particulate material bin or bins, a fan, and a primary conduit extending from the fan past a particulate material inlet and thence to a primary distribution location whereby to distribute particulate material into a plurality of smaller secondary conduits, the arrangement being characterised according to this invention in that the primary conduit includes at least between the particulate material inlet and the primary distribution location across a lowermost inner face of the conduit, an upwardly deflecting vane to spread material directed thereagainst and positioned between this last mentioned vane and the primary distribution location, and in a position to be in a general path of material upwardly deflected by the first said vane, a second said vane located at an uppermost inner face of the conduit and arranged to downwardly deflect and spread material directed thereagainst.
Claim 2
Dependent Claim
152 words
An airflow particulate material transfer arrange-ment for an airflow seeder of a type including a bulk particulate material bin or bins, a fan, and a primary conduit extending from the fan past a particulate material inlet and thence to a primary distribution location whereby to distribute particulate material into a plurality of smaller secondary conduits, the arrangement being characterised according to this invention in that the primary conduit includes at least between the particulate material inlet and the primary distribution location across a lowermost inner face of the conduit, an upwardly deflecting vane to spread material directed thereagainst and positioned between this last mentioned vane and the primary distribution location, and in a position to be in a general path of material upwardly deflected by the first said vane, a second said vane located at an uppermost inner face of the conduit and arranged to downwardly deflect and spread material directed thereagainst.
Claim 3
Dependent Claim
48 words
An airflow particulate material transfer arrange-ment as in Claim 1 further characterised in that the primary distribution location includes a plurality of inlets to secondary conduits located each in adjacent relationship to others of the secondary conduits and all in a streamline airflow path from the primary conduit.
Claim 4
Dependent Claim
103 words
An airflow particulate material transfer arrangement as in either of Claims 1 or 2 further characterised in that the inlets to the secondary conduits are located so as to collect approximately equal amounts of particulate materials from that carried along the primary conduit, and a vane or vanes located in the primary conduit in the immediately pre-ceding vicinity of the primary distribution location, said vane or vanes being at least substantially aligned in a substantially vertical plane and adjustable in position about a substantially vertical axis so as to enable adjustment of the proportion of particulate materials being collected by the respective inlets.
Claim 5
Dependent Claim
70 words
An airflow particulate material transfer arrangement as in claim 1 or 2 in which the primary conduit is of elongate proportion in cross-section in at least in the vicinity of the primary distribution location with the longest sides of the elongation shape in cross-section being substantially horizontal and the inlets to the secondary conduits being substantially of the same size being uniformly distributed across the outlet of the primary conduit.
Claim 6
Dependent Claim
50 words
An airflow particulate material transfer arrangement as in either of Claims 1 or 2 further characterised in that the primary conduit from the fan through to the secondary conduits is of substantially the same area in cross-section throughout its length except in the vicinity of the particulate material inlet. 14.
Claim 7
Dependent Claim
65 words
An airflow particulate material transfer arrange-ment as in either of Claims 1 or 2 further characterised in that there are at least six secondary conduits arranged with inlets located at the primary distribution location, each of the inlets being arranged with one of the inlets adjacent another of the inlets and such inlets being distributed in symmetrical alignment across the outlet of the primary conduit.
Claim 8
Dependent Claim
94 words
An airflow particulate material transfer arrange-ment as in either of Claims 1 or 2 further characterised in that there are at least six secondary conduits arranged with inlets located at the primary distribution location, each of the inlets being arranged with one of the inlets adjacent another of the inlets and such inlets being distributed in symmetrical alignment across the outlet of the primary conduit, and at least in the vicinity of the outlet of the primary conduit the shape of this includes substantially planar upper and lower walls and substantially arcuate side walls.
Claim 9
Dependent Claim
137 words
An airflow particulate material transfer arrange-ment as in either of Claims 1 or 2 further characterised in that the inlets to the secondary conduits are located so as to collect approximately equal amounts of particulate materials from that carried along the primary conduit, and a vane or vanes located in the primary conduit in the immediately preceding vicinity of the primary distribution location, said vane or vanes being at least substantially aligned in a substantially vertical plane and adjustable in position about a sub-stantially vertical axis so as to enable adjustment of the proportion of particulate materials being collected by the respective inlets, and each of the vanes which are adjustable about a substantially vertical axis include adjustment means located externally of the primary conduit to enable adjustment of the vane from outside of the primary conduit.
