Abstract

The pressure of a fluid passing through several air entrainers can be controlled so as to more effectively move particulate material from one or more bulk hoppers to an end location. This is accomplished through use of an integrated, electric fluid pressure source, such as a fan in one or more of the segments. The pressure can be increased based upon a speed of an agricultural implement or a weight of the particulate material and/or the pneumatic flow can compensate for distance the seed must travel before planting. The entrainer can thus be installed with a high speed planting implement, thereby reducing downtime and facilitating repair.

First claim

What is claimed is:

1 . A particulate delivery assembly, comprising:
a plurality of entrainers operatively connected to one another, each of an entrainer of the plurality of entrainers comprising:
at least one particulate entrance that leads to a primary flow path;
a bypass flow path separate from the primary flow path; and
at least one outlet that combines an end of the primary flow path and an end of the bypass flow path; and
a plurality of integrated, electric fluid pressure sources positioned inside the particulate delivery assembly, wherein one integrated, electric fluid pressure source of the plurality of integrated, electric fluid pressure sources is positioned inside multiple of the plurality of entrainers; wherein the one integrated, electric fluid pressure source provides fluid pressure to the entrainer to move the particulate in the primary flow path and to push the particulate out the at least one outlet with assistance from fluid pressure of the bypass flow path, and towards an end location.

2 . The particulate delivery assembly of claim 1 , wherein the end location is a row unit of an agricultural implement.

3 . The particulate delivery assembly of claim 1 , wherein the pressure is negative pressure.

4 . The particulate delivery assembly of claim 1 , wherein the pressure is positive pressure.

5 . The particulate delivery assembly of claim 1 wherein the one integrated, electric fluid pressure source is operatively connected to a flow control for individually adjusting the pressure at each one of the plurality of entrainers.

6 . The particulate delivery assembly of claim 5 wherein the flow control is a valve, an insert, or a baffle.

7 . The particulate delivery assembly of claim 6 wherein the valve, the insert, or the baffle is positioned downstream at a row unit.

8 . The particulate delivery assembly of claim 1 wherein the plurality of entrainers comprises more than three entrainers.

9 . The particulate delivery assembly of claim 1 further comprising upper mounting brackets for mounting the plurality of entrainers to bulk seed storage members of an agricultural implement.

10 . A particulate delivery assembly, comprising:
a plurality of entrainers operatively connected to one another, each of said entrainers comprising:
at least one particulate entrance;
and at least one outlet; and
an integrated, electric fluid pressure source positioned to provide fluid pressure to the entrainer to move the particulate out the at least one outlet and towards an end location;
a plurality of upper mounting brackets for mounting the plurality of entrainers to bulk seed storage members of an agricultural implement; and a pivot connection for allowing pivotal movement between the plurality of entrainers and the bulk seed storage members.
