Abstract
A trailer provides a slurry hauling tank having an auger mounted for swinging movement inside the tank. A rotary hydraulic motor inside the tank drives the auger and is powered by fluid delivered through a rotary fitting extending through the tank wall. Relatively stiff stainless steel conduit connects the rotary fitting to the auger motor. The auger is oscillated through an arc while the trailer is being loaded, towed toward a disposal site and during unloading by a hydraulic motor on the outside of the tank. A hydraulic circuit alternately drives the motor in one direction and then in another direction. In one embodiment, the hydraulic circuit reverses by use of a pressure responsive cycling valve. In another embodiment, microswitches are used to reverse the hydraulic motor.
Claims16
A vehicle for hauling slurries along a roadway, comprising
- a wheeled frame having thereon a tank including an inlet and an outlet;
- means for agitating materials in the tank including an agitator having an axis, a motor for rotating the agitator about its axis and means mounting the agitator for moving the agitator axis in a predetermined path in the tank;
- and
- means for continuously moving the agitator mounting means when the vehicle is moving along the roadway.
A vehicle for hauling slurries along a roadway, comprising
- a wheeled frame having thereon a tank including an inlet and an outlet;
- means for agitating materials in the tank including an agitator in the tank having a first axis and a fluid first motor in the tank for rotating the agitator about the first axis;
- means swingably mounting the agitator about a second axis including a first bearing member affixed to the tank having a passage therein, a second bearing member received in the first bearing member passage and extending from a location outside the tank to a location inside the tank and means connecting the agitator to the second bearing member for rotation therewith about the second axis;
- a second motor for swinging the agitator mounting means about the second axis;
- a fluid pump and conduit means connecting the fluid pump to the first motor including the second bearing member, the conduit means comprising
- the second bearing member comprising first and second separate passages therethrough,
- first and second conduits connecting the first and second passages inside the tank to the first motor, and
- third and fourth conduits connecting the first and second passages outside the tank to the fluid pump.
A method of moving a slurry along a roadway with a vehicle comprising a wheeled frame having thereon a tank including an inlet and an outlet, means for agitating materials in the tank including an agitator having an axis, a motor for rotating the agitator about its axis, means mounting the agitator for moving the agitator axis in a predetermined path in the tank and means for oscillating the agitator mounting means between first and second limit positions, the method comprising the step of moving the agitator mounting means while the vehicle is moving along the roadway.
