Abstract
A truck platform is elevated at one end and then moved rearwardly by pulsation cylinders which slowly accelerate and then rapidly decelerate the platform and truck. The abrupt deceleration causes the material in the truck to continue to move rearwardly separating from the truck floor and move out of the truck in a stair step fashion through repeating pulsations. The angle in which the platform needs to be raised is minimized by the application of pulsation forces to the system thereby improving the safety and ease of unloading the truck.
Claims22
A vehicle dumping apparatus comprising,
- a vehicle platform having front and rear ends,
- a hinge means pivotally connecting said rear end to a support,
- a power means engagable with said platform for pivotably raising and lowering said platform front end, and pulsation means connected to said platform for reciprocating said platform when in said raised position, and said pulsation means moving said platform through a cycle of movement which includes movement in a rearward direction, abrupt deceleration, and a return in a forward direction with the time of movement in the rearward direction being less than the time of movement in the forward direction.
A vehicle dumping apparatus comprising,
- a vehicle platform having front and rear ends,
- a hinge means pivotally connecting said rear end to a support,
- a power means engagable with said platform for pivotably raising and lowering said platform front end, and
- pulsation means including a power cylinder connected to the rear end of said platform for reciprocating said platform when in said raised position.
A vehicle dumping apparatus comprising,
- a vehicle platform having front and rear ends,
- a hinge means pivotally connecting said rear end to a support,
- a power means engagable with said platform for pivotably raising and lowering said platform front end, and
- pulsation means connected to said platform for reciprocating said platform horizontally only when in said raised position.
The method of unloading a container on a platform elevated at an angle, including the steps of,
- connecting a pulsation means to said platform, and
- operating said pulsation means to cause said platform to move through multiple cycles which include movement in a rearward direction followed by abrupt deceleration, and a return in a forward direction, with the time of movement in the rearward direction being less than the time of movement in the forward direction.
A container dumping apparatus comprising,
- a container platform having front and rear ends,
- a hinge means pivotally connecting said rear end to a support,
- a power means engagable with said platform for pivotably raising and lowering said platform front end, and
- pulsation means connected to said platform for moving said platform horizontally only rearwardly and forwardly relative to said support when in said raised position for moving material rearwardly in a container on said platform for unloading said container.
