Abstract

The current disclosure relates to a tank trailer for transporting meat packaging by-products. The tank trailer has a cylindrical body having a sloped rear end. An opening is formed in the sloped rear end, and a gate selectively blocks the opening. A locking mechanism is provided to securely lock the gate to the cylindrical body, thereby sealing the cylindrical body. The sloped rear end forms a chute through which meat by-products can be poured. The chute extends for a distance rearwardly of the trailer'"'"'s rear wheel assembly.

Claims

1. A tank trailer comprising:

a cylindrical body including;

a top;

a bottom;

a front;

a rear;

wherein a longitudinal axis extends between the front and the rear, and a vertical plane extends between the top and the bottom, and wherein the top, bottom, front, and rear bound and define an interior compartment adapted to carry a load;

wherein the rear is oriented at an acute angle relative to the vertical plane;

wherein the rear defines an opening that is in communication with the interior compartment;

a gate;

wherein the gate is movable between an open position and a closed position, and when in the closed position, the gate blocks the opening;

an actuator; and

a locking mechanism;

wherein the actuator is operative to cause the locking mechanism to rotate a center plate in one of a clockwise and a counter-clockwise direction, wherein the locking mechanism is movable between a locked position and an unlocked position, and when in the locked position, the locking mechanism locks the gate to the cylindrical body; and

wherein the locking mechanism is remotely controllable.

2. The tank trailer as defined in claim 1, further comprising a wheel assembly operatively engaged with the bottom, and wherein the bottom extends longitudinally and rearwardly further outwardly from the wheel assembly than does the top.

3. The tank trailer as defined in claim 1, wherein the rear is sloped downwardly and rearwardly from the top.

4. The tank trailer as defined in claim 1, wherein the body further includes a left side and a right side that extend from the front to the rear;

and wherein a portion of each of the left side and right side angles downwardly and rearwardly from the top to the bottom; and

wherein the portions of the left side and the right side and a portion of the bottom define a chute through which the load exits from the interior compartment.

5. A method of dumping a load out of a tank trailer, comprising steps of:

providing a tank trailer having a cylindrical body including a top, a bottom, a front and a rear;

wherein a longitudinal axis extends between the front and rear, and a vertical plane extends between the top and bottom, and wherein the top, bottom, front, and rear bounds and defines a compartment;

orienting the rear at an acute angle relative to the vertical plane;

defining an opening in the rear that is in communication with the compartment;

providing a gate at the rear, wherein the gate is selectively movable between a closed position and an open position;

placing a load in the compartment and moving the gate to the closed position to close off access to the compartment;

moving a locking mechanism provided on the gate or on the body from an unlocked position to a locked position;

carrying the load in the compartment;

defining a chute in a rear end of the body;

wherein the chute comprises a portion of each of a left side and a right side of the body as well as a portion of the bottom; and

moving the locking mechanism from the locked position to the unlocked position;

wherein the moving of the locking mechanism to the unlocked position includes;

actuating a first actuator of the locking mechanism to rotate a center plate in one of a clockwise and a counter-clockwise direction;

moving locking rods of the locking mechanism inwardly towards the center plate;

actuating a second actuator that is operatively engaged with the body and the gate; and

the method further includes;

moving the gate from the closed position to the open position; and

removing the load from the compartment through the chute.

6. The method of dumping a load in claim 5, further comprising a step of:

remotely controlling the locking mechanism.

7. The method of dumping a load in claim 5, further comprising a step of:

raising a front end of the body from a first position to a second position prior to the step of removing the load through the chute.

8. The method of dumping a load in claim 5, wherein the moving of the locking rods of the locking mechanism further comprises a step of disengaging locking rods from brackets provided on the body.

9. The method of dumping a load in claim 5, wherein steps of actuating one or both first and second actuator is further accomplished by engaging a remote controller.

10. The method of dumping a load in claim 5, further comprising a step of raising a forward section of the tank trailer relative to a rearward section of the tank trailer.

11. A tank trailer comprising:

a cylindrical body having a circumferential wall, wherein the body includes a front and a rear; and

wherein the wall bounds and define an interior compartment adapted to carry a load, and wherein the rear includes an inclined rear edge that bounds and defines an opening to the compartment, and wherein the opening is of substantially a same circumference as the circumferential wall;

a gate movable between an open position and a closed position, and when in the closed position, the gate blocks the opening;

a locking mechanism operative to move the gate between a locked position and an unlocked position, and when the locking mechanism is in the locked position the gate is unable to move to the open position;

wherein the locking mechanism comprises;

a center plate;

a first actuator operative to rotate the center plate in one of a clockwise direction and a counter-clockwise direction;

at least one locking rod operative to selectively move one of inwardly toward the center plate and outwardly toward the rear of the circumferential wall; and

a second actuator operatively engaged with the cylindrical body and the gate, wherein the second actuator is actuated to move the gate between the open position and the closed position.

12. The tank trailer as defined in claim 11, further comprising a remote control that is operatively engageable with the locking mechanism, and the remote control is actuated to move the locking mechanism between the locked and unlocked positions.
