Abstract

A movable agricultural product applicator system for dispensing various agricultural-related products along the ground surface of agricultural crops is provided. The application system provides a hose assembly interconnecting a supporting boom and an applicator, wherein the applicator drags along the ground surface dispensing product as the supporting boom moves by a carrier. The application system may include a swivel connection facilitating a rotational and pivotal connection of the hose assembly to the supporting boom, wherein a mounting assembly removably mounts the application system to the supporting boom. The hose assembly is designed with bending properties that enable the applicator to self-center and locate rows between crops as it is being dragged along the ground surface, as well as enable the applicator to surf above obstacles.

Claims

1. A system for dispersing product on a field of crops using a mobile supporting boom spanning portions of the field of crops, comprising:

a product delivery hose assembly extending downwardly from the boom, the product delivery hose assembly having a proximal end and a distal end;

at least one tube operatively coupled to the boom, the at least one tube comprising a plurality of tube segments operatively coupled together to permit flexing of the at least one tube, the at least one tube having an interior for retaining the product delivery hose assembly extending there through;

at least one nozzle coupled to and in fluid communication with the distal end of the product delivery hose assembly;

a bracket disposed proximate to the distal end of the product delivery hose assembly to position the at least one nozzle in an angled position; and

a hang hook connected to the at least one tube, the hang hook being adapted to retain an adjacent at least one tube when the product delivery hose assembly is not being used,

wherein product flowing through the product delivery hose assembly is dispersed through the at least one nozzle in a upward direction to spray a field of crops.

2. The system of claim 1, wherein the plurality of tube segments comprise alternating rigid and flexible tube segments operatively coupled together.

3. The system of claim 2, further comprising at least one coupler adapted to couple the rigid and flexible tube segments together.

4. The system of claim 2, further comprising a spring swivel connection rotatably connecting a proximal end of the at least one tube to the supporting boom, wherein the swivel connection is movable from a retracted position to an extended position.

5. The system of claim 4, wherein the spring swivel connection further comprises:

a boom extension plate interconnecting the product delivery hose assembly and the supporting boom, wherein the boom extension plate forms a bearing hole; and

a tube bracket joined to a plate post, wherein the tube bracket attaches to the proximal end, wherein the plate post extends through the bearing hole so that a protruding portion of the plate post is provided, and wherein the spring is disposed on the protruding portion.

6. The system of claim 1, further comprising an applicator connected to the distal end to direct a flow of product along a ground surface.

7. The system of claim 6, wherein the applicator further comprises two applicator tubes that diverge, and wherein each applicator tube is in fluid communication with the at least one product delivery hose.

8. The system of claim 6, wherein the applicator further comprises two applicator tubes that diverge, and wherein the two applicator tubes are adapted to receive a portion of at least one product delivery hose.

9. The system of claim 7, further comprising two ground tubes, each ground tube being adapted to receive a distal end of an applicator tube, wherein each ground tube is adapted to direct a flow of product onto a ground surface.

10. A product dispenser adapted to disperse a product on a field of crops using a mobile supporting boom spanning portions of the field of crops, comprising:

a hose assembly extending from a proximal end to a distal end, wherein the hose assembly comprising a plurality of tubular components, wherein at least one of the plurality of tubular components extends along a longitudinal axis, and wherein the at least one of the plurality of tubular components is adapted to bend about the longitudinal axis in any direction;

at least one nozzle operatively coupled to the distal end of the product delivery hose assembly adapted to spray product on the field of crops;

a swivel connection rotatably connecting the proximal end to the supporting boom, wherein the swivel connection is movable from a retracted position to an extended position, and wherein the swivel connection comprises;

a boom extension plate interconnecting the hose assembly and the supporting boom, wherein the boom extension plate forms a bearing hole;

a tube bracket joined to a plate post, wherein the tube bracket attaches to the proximal end, wherein the plate post extends through the bearing hole so that a protruding portion of the plate post is provided; and

a spring disposed on the protruding portion so as to bias the swivel connection in the retracted position;

a hang hook connected to the tube bracket, the hang hook being adapted to retain an applicator when the product dispenser is not being used;

an applicator connected to the distal end and extending beyond the at least one nozzle; and

a mounting assembly for removably securing the swivel connection to the supporting boom.

11. The dispenser of claim 10, further comprising an extension connector interconnecting the supporting boom and the boom extension plate.

12. The dispenser of claim 11, further comprising a boom arm connected to the supporting boom, wherein the boom arm is telescopically connected to the extension connector, positionable in an extended position and a retracted position.

13. The dispenser of claim 10, wherein the mounting assembly comprises a u-clip bolt dimensioned and adapted to removably secure the boom arm to the supporting boom, wherein the u-clip bolt slides out of the boom arm.

14. A product dispersing assembly used on a field of crops utilizing a mobile supporting boom having a reservoir containing product that spans a portions of the field of crops, comprising:

a product hose assembly extending from a proximal end to a distal end, the proximal end being in fluid communication with the reservoir containing the product;

a tube assembly having an interior to receive and protect the product hose assembly from damage, the tube assembly comprising;

at least one upper tubular component extending along a longitudinal axis to protect a portion of the product hose assembly hanging from the boom, and wherein the at least one upper tubular component is adapted to bend about the longitudinal axis in any direction;

a plate coupled to a distal end of the upper tubular component;

at least a pair of diverting tubes coupled to the plate and extending angularly away from the upper tubular component, the product hose assembly extending through a portion of the at least pair of diverting tubes;

a hang hook connected to the at least one upper tube component, the hang hook being adapted to retain an adjacent at least one tube assembly when the product delivery hose assembly is not being used; and

at least one nozzle fluidly coupled to a distal end of the product hose assembly to spray product on the field of crops, the at least one nozzle being disposed between the upper tubular component and the at least a pair of diverting tubes.

15. The assembly of claim 14, wherein the upper tubular component is segmented into a plurality of tubular components flexibly coupled together to permit bending of the upper tubular component.

16. The assembly of claim 15, further comprising at least one flex hose coupled to and extending between the tubular components to permit the flexing of the upper tubular component.

17. The system of claim 14, further comprising a bracket coupled to the plate and the at least one nozzle.

18. The assembly of claim 14, further comprising a swivel connection rotatably connecting the proximal end to the supporting boom, wherein the swivel connection is movable from a retracted position to an extended position.

19. The assembly of claim 18, wherein the swivel connection comprises:
