Abstract

An agricultural sprayer for metered application of a liquid includes a chassis, and a carrier tank fixedly mounted to the chassis. The carrier tank is configured for containing a carrier liquid therein. One or more active ingredient tanks are each configured for containing an active ingredient therein. A storage area associated with the chassis is configured for and dedicated to removable storage of each active ingredient tank.

First claim

What is claimed is:

1. A self-propelled or towed agricultural sprayer for metered application of a liquid, said agricultural sprayer comprising:
a chassis;
a carrier tank fixedly mounted to said chassis, said carrier tank being configured for containing a carrier liquid therein;
at least one wing boom carried by said chassis, said wing boom including a plurality of spray nozzles directed generally downward;
at least one active ingredient tank, each said active ingredient tank being configured for containing an active ingredient therein;
a storage area associated with said chassis which is configured for and dedicated to removable storage of each said active ingredient tank; and
at least one fluid connector associated with said storage area, each said fluid connector fluidly connected to the plurality of spray nozzles and automatically forming a sealed connection with a corresponding said active ingredient tank upon placement of said active ingredient tank within said storage area, each said fluid connector being configured to pierce and seal with a corresponding said active ingredient tank.

2. The agricultural sprayer of claim 1 , wherein each said fluid connector includes a reservoir upstanding from said storage area, and a piercing member centrally located within said reservoir.

3. The agricultural sprayer of claim 2 , wherein each said active ingredient tank includes a downwardly extending nozzle which is received within said reservoir.

4. The agricultural sprayer of claim 3 , wherein said nozzle is a tapered nozzle.

5. The agricultural sprayer of claim 1 , wherein each said active ingredient tank has a cover with a common predefined configuration and a suction line extending from said cover into said active ingredient tank.

6. The agricultural sprayer of claim 5 , wherein each said cover includes a quick-attach fitting for attachment with a corresponding fluid line onboard said sprayer.

7. The agricultural sprayer of claim 1 , further including at least one restraining device, each said restraining device restraining a respective said active ingredient tank within said storage area.

8. The agricultural sprayer of claim 7 , wherein each said restraining device comprises a strap.

9. The agricultural sprayer of claim 1 , wherein said storage area includes a support structure fixedly mounted to said chassis, said support structure having a generally horizontal platform for supporting each said active ingredient tank.

10. The agricultural sprayer of claim 1 , wherein said at least one active ingredient tank comprises a plurality of active ingredient tanks.

11. The agricultural sprayer of claim 1 , wherein each said active ingredient tank has a predefined shape and size.

12. The agricultural sprayer of claim 11 , wherein said storage area is a tote storage area, and each said active ingredient tank is configured as a tote.

13. A self-propelled or towed agricultural sprayer, including:
a chassis;
a carrier tank fixedly mounted to said chassis, said carrier tank being configured for containing a carrier liquid therein;
at least one wing boom carried by said chassis, said wing boom including a plurality of spray nozzles directed generally downward;
a support structure fixedly mounted to said chassis, said support structure having a generally horizontal platform;
at least one active ingredient tank, each said active ingredient tank being removably positioned on and supported by said horizontal platform; and
at least one fluid connector associated with said horizontal platform, each said fluid connector fluidly connected to the plurality of spray nozzles and automatically forming a sealed connection with a corresponding said active ingredient tank upon placement of said active ingredient tank within said horizontal platform, each said fluid connector being configured to pierce and seal with a corresponding said active ingredient tank.

14. The agricultural sprayer of claim 13 , wherein each said fluid connector includes a reservoir upstanding from said horizontal platform, and a piercing member centrally located within said reservoir.

15. The agricultural sprayer of claim 14 , wherein each said active ingredient tank includes a downwardly extending nozzle which is received within said reservoir.

16. The agricultural sprayer of claim 15 , wherein said nozzle is a tapered nozzle.

17. The agricultural sprayer of claim 13 , wherein each said active ingredient tank has a cover with a common predefined configuration and a suction line extending from said cover into said active ingredient tank.

18. The agricultural sprayer of claim 17 , wherein each said cover includes a quick-attach fitting for attachment with a corresponding fluid line onboard said sprayer.

19. The agricultural sprayer of claim 13 , further including at least one restraining device, each said restraining device restraining a respective said active ingredient tank within said horizontal platform.

20. The agricultural sprayer of claim 19 , wherein each said restraining device comprises a strap.

21. The agricultural sprayer of claim 13 , wherein said at least one active ingredient tank comprises a plurality of active ingredient tanks.

22. The agricultural sprayer of claim 13 , wherein each said active ingredient tank has a predefined shape and size.

23. The agricultural sprayer of claim 22 , wherein said horizontal platform is a tote storage area, and each said active ingredient tank is configured as a tote.

24. A method of using a self-propelled or towed agricultural sprayer, said method comprising the steps of:
filling a carrier tank fixedly mounted to a chassis with a carrier liquid;
placing an active ingredient tank in a dedicated storage area associated with said chassis;
connecting said active ingredient tank with a fluid connector associated with said storage area, said fluid connector automatically piercing and sealing with said active ingredient tank upon said placing of said active ingredient tank in said dedicated storage area;
discharging carrier liquid from the carrier tank;
metering an active ingredient from said active ingredient tank into the carrier liquid to form a mixed liquid, and
discharging said mixed liquid directly to an agricultural field through at least one wing boom connected to said chassis, said wing boom including a plurality of spray nozzles directed generally downward.

25. The method of claim 24 , wherein each said fluid connector includes a reservoir upstanding from said storage area, and a piercing member centrally located within said reservoir.

26. The method of claim 25 , wherein each said active ingredient tank includes a downwardly extending nozzle which is received within said reservoir.

27. The method of claim 24 , wherein said active ingredient tank has a cover and a suction line extending from said cover into said active ingredient tank.
