Abstract

An agricultural implement comprising a chassis, a plurality of wheels coupled to the chassis, and a pneumatic distribution system coupled to the chassis, the pneumatic distribution system including at least one tank capable of storing and releasing agricultural product; a metering arrangement including conduit capable of transporting the agricultural product; and a blower fan arrangement configured to transport the agricultural product, the blower fan arrangement including a first blower fan and a second blower fan, each blower fan having an air inlet and an air outlet, and a transition section fluidly coupling the air outlet of the first blower fan with the air inlet of the second blower fan.

Claims

1. An agricultural implement, comprising:

a chassis;

a plurality of wheels coupled to the chassis; and

a pneumatic distribution system coupled to the chassis, the pneumatic distribution system including;

at least one tank capable of storing and releasing agricultural product;

a metering arrangement including conduit capable of transporting the agricultural product; and

a blower fan arrangement configured to transport the agricultural product, the blower fan arrangement including a first blower fan and a second blower fan, each blower fan having an air inlet and an air outlet, and a transition section fluidly coupling the air outlet of the first blower fan with the air inlet of the second blower fan,

wherein the transition section includes an inlet end and an outlet end, and is generally pyramid-shaped with a truncated inlet end smaller than the outlet end, and

wherein the transition section has a generally square-shaped cross-section of the outlet end.

2. The agricultural implement of claim 1, wherein the pneumatic distribution system is operated by a single control for both blower fans.

3. The agricultural implement of claim 1, wherein the pneumatic distribution system is operated by a control for each blower fan.

4. A pneumatic distribution system capable of distributing an agricultural product, the pneumatic distribution system comprising:

at least one tank capable of storing and releasing the agricultural product;

a metering arrangement including conduit capable of transporting the agricultural product; and

a blower fan arrangement configured to transport the agricultural product, the blower fan arrangement including a first blower fan and a second blower fan, each blower fan having an air inlet and an air outlet, and a transition section fluidly coupling the air outlet of the first blower fan with the air inlet of the second blower fan,

wherein the pneumatic distribution system is operated by a control for each blower fan.

5. The pneumatic distribution of claim 4, wherein the transition section includes an inlet end and an outlet end, and is generally pyramid-shaped with a truncated inlet end smaller than the outlet end.

6. The pneumatic distribution of claim 5, wherein the transition section has a generally square-shaped cross-section of the outlet end.

7. The pneumatic distribution of claim 5, wherein the transition section has a generally rectangular-shaped cross-section of the inlet end.

8. An agricultural implement, comprising:

a chassis,

a plurality of wheels coupled to the chassis; and

a pneumatic distribution system coupled to the chassis, the pneumatic distribution system including;

at least one tank capable of storing and releasing agricultural product;

a metering arrangement including conduit capable of transporting the agricultural product; and

a blower fan arrangement configured to transport the agricultural product, the blower fan arrangement including a first blower fan and a second blower fan, each blower fan having an air inlet and an air outlet, and a transition section fluidly coupling the air outlet of the first blower fan with the air inlet of the second blower fan,

wherein the transition section includes an inlet end and an outlet end, and is generally pyramid-shaped with a truncated inlet end smaller than the outlet end, and

wherein the transition section has a generally rectangular-shaped cross-section of the outlet end.

9. The agricultural implement of claim 8, wherein the pneumatic distribution system is operated by a single control for both blower fans.

10. The agricultural implement of claim 8, wherein the pneumatic distribution system is operated by a control for each blower fan.
