Abstract

An extendable mobile fluid carrying apparatus including a first frame configured to couple to a tractor. A fluid container is coupled to the first frame and configured to rotate about a pivot device of the first frame. The container defines a closable orifice configured to decant a fluid from the container. A high-CFM blower is coupled to the container and configured to draw a vacuum. A lift mechanism is coupled to the first frame and the fluid container and configured to lift the fluid container to an angle greater than 45° relative to the first frame. A second frame is slidingly coupled to the first frame, with the second frame configured to extend away from the first frame a predetermined distance. The second frame includes a wheel set. The tractor may include a power takeoff mechanism coupled to a prime mover and to the blower.

Claims (37)

1. An extendable mobile fluid carrying apparatus comprising:

a first frame having a first end and a second end, with the first end configured to couple to a tractor;

a fluid container having a closed end, the container pivotally coupled to the first frame and configured to rotate about a pivot device disposed proximate the second end of the first frame, with the container defining a closable orifice configured to decant a fluid from the container and with a swing door configured to selectively cover the closable orifice;

a high-CFM blower mounted on the tractor and selectively coupled to the closed end of the container through a vacuum coupler configured to couple to the blower coupled to the fluid container, with the vacuum coupler including a male portion and a female portion, and mounted on the first frame with the blower configured to draw a vacuum, the female portion includes a flexible collar configured to fluidly seal with the male portion and disengage when the fluid container is raised;

a lift mechanism coupled to the first frame and the fluid container and configured to lift the closed end of the fluid container to an angle not less than 45° nor more than 80° relative to the first frame to decant the fluid; and lower the closed end to a position parallel to the first frame; and

a second frame slidingly coupled to the first frame, the second frame configured to automatically extend away from the first frame a pre-determined distance, with the second frame including a wheel set, with the first frame and second frame including the wheel set configured for one of on-road and off-road conditions.

2. The extendable mobile fluid carrying apparatus of claim 1 , wherein the fluid container is a tube having a circular interior cross-section and including a full opening, swing door pivotally coupled to the tube at the closable orifice, with the door configured to move from a closed position to an open position.

3. The extendable mobile fluid carrying apparatus of claim 2 , wherein the door opening movement is facilitated by one of gravity and a hydraulic cylinder.

4. The extendable mobile fluid carrying apparatus of claim 2 , wherein the wheel set is retractable.

5. The extendable mobile fluid carrying apparatus of claim 1 , wherein the tractor includes a power take-off mechanism coupled to a prime mover and to the blower.

6. The extendable mobile fluid carrying apparatus of claim 1 , including a second wheel set coupled to the second frame.

7. The extendable mobile fluid carrying apparatus of claim 1 , wherein the angle of the fluid container relative to the first frame is at least 75°.

8. The extendable mobile fluid carrying apparatus of claim 1 , wherein the angle of the fluid container relative to the first frame is at least 60°.

9. The extendable mobile fluid carrying apparatus of claim 1 , wherein the first frame, second frame and fluid container each are composed of material from a group consisting of steel, aluminum, and a combination of steel and aluminum.

10. The extendable mobile fluid carrying apparatus of claim 1 , wherein the wheel set is retractable.

11. An extendable mobile fluid carrying apparatus comprising:

a tractor including a prime mover;

a high-CFM blower apparatus mounted on the tractor and configured to draw a vacuum;

a first frame having a first end and a second end, with the first end configured to couple to the tractor;

a fluid container having a closed end, the container coupled to the first frame and configured to rotate about a pivot device disposed proximate the second end of the first frame, with the container defining a closable orifice configured to decant a fluid from the container, with the closed end of the container selectively coupled to the blower with a vacuum coupler configured to couple to the blower coupled to the fluid container, with the vacuum coupler including a male portion and a female portion, and mounted on the first frame, the female portion includes a flexible collar configured to fluidly seal with the male portion and disengage when the fluid container is raised;

a lift mechanism coupled to the first frame and the fluid container and configured to lift the closed end of the fluid container to an angle not less than 45° nor more than 80° relative to the first frame to decant the fluid and lower the closed end to a position parallel to the first frame; and

a second frame slidingly coupled to automatically extend away from the first frame a pre-determined distance, with the second frame including a wheel set, with the tractor, first frame and second frame including the wheel set configured for one of on-road and off-road conditions.

12. The extendable mobile fluid carrying apparatus of claim 11 , wherein the fluid container is a tube having a circular interior cross-section and including a full opening, swing door pivotally coupled to the tube at the closable orifice, with the door configured to move from a closed position to an open position.

13. The extendable mobile fluid carrying apparatus of claim 12 , wherein the door opening movement is facilitated by one of gravity and a hydraulic cylinder.

14. The extendable mobile fluid carrying apparatus of claim 11 , wherein the tractor includes a power take-off mechanism coupled to the blower.

15. The extendable mobile fluid carrying apparatus of claim 11 , including a second wheel set coupled to the second frame.

16. The extendable mobile fluid carrying apparatus of claim 11 , wherein the angle of the fluid container relative to the first frame is at least 75°.

17. The extendable mobile fluid carrying apparatus of claim 11 , wherein the first frame, second frame and fluid container each are composed of material from a group consisting of steel, aluminum, and a combination of steel and aluminum.

18. A vehicle comprising:

a support structure including a prime mover configured to provide a motive force coupled to the support structure and a steerable wheel set coupled to the support structure;

a trailer including a first frame having a first end and a second end, with the first end configured to couple to the support structure;

a fluid container having a closed end, the container pivotally coupled to the first frame and configured to rotate about a pivot device disposed proximate the second end of the first frame, with the container defining a closable orifice configured to decant a fluid from the container, the fluid container is a tube having a circular interior cross-section and including a full opening, swing door pivotally coupled to the tube at the closable orifice, with the door configured to move from a closed position to an open position;

a high-CFM blower mounted on the support structure selectively coupled to the closed end of the container and configured to draw a vacuum and selectively couple to the container with a vacuum coupler configured to couple to the blower coupled to the fluid container, with the vacuum coupler including a male portion and a female portion, and mounted on the first frame of the trailer, the female portion includes a flexible collar configured to fluidly seal with the male portion and disengage when the fluid container is raised;

a power take-off mechanism coupled to the blower and the prime mover;

a lift mechanism coupled to the first frame and the fluid container and configured to lift the closed end of the fluid container to an angle not less than 45° nor more than 80° relative to the first frame to decant the fluid and lower the closed end to a position parallel to the first frame; and

a second frame slidingly coupled to the first frame, the second frame configured to automatically extend away from the first frame a pre-determined distance , with the second frame including a wheel set, with the support structure, first frame and second frame including the wheel set configured for one of on-road and off-road conditions.

19. The vehicle of claim 18 , wherein the angle of the fluid container relative to the first frame is at least 75°.
