ABSTRACT:
A flail auger assembly is disclosed which is useful for unloading semi-liquid material from a holding tank mounted on a tractor drawn trailer. A rotatably mounted shaft extends lengthwise through the lower portion of the tank. One end of the shaft penetrates the front wall of the tank enabling connection with the power takeoff of the tractor. The second end penetrates the rear wall of the tank where it connects with the impeller of the discharge pump. A plurality of flails extend radially outward at regular intervals along the shaft. The flails are pivotally attached via pins which secure them to brackets welded to the rotatably mounted shaft. The pivotal axis of each flail allows it to aggressively attack the material in the tank while at the same time limiting the power drain on the tractor since the radius of effectiveness decreases as a function of increasing load. The outward extending second end of the flails are twisted with respect to the pivot axes to impart both a chopping action and a rearward thrust to the semi-liquid material in the holding tank. The rearward thrust forces the semi-liquid slurry to enter the discharge pump via a port in the lower rear wall of the tank.
