Abstract
An improved auger is used for conveying flowable materials, such as liquid and semi-solid manure, through a bed of a container such as a manure spreader and out through a discharge opening. The auger has a shaft with a back end and a front end, a continuous blade, and paddles for discharging the manure. The continuous blade extends radially outwardly from the shaft and includes helical portions and at least one plate portion which is substantially perpendicular to an axis of the auger. The plate portions extend between the helical portions of the blade to make the blade substantially continuous. The rotation of the auger causes helical portions of the blade to accelerate the manure in a direction of the front end wall and causes the plate portions to slow the movement of manure so that the rate of flow of manure is controlled and boiling action of manure against the front end wall of the container is inhibited. Additionally, the rotation causes the plate portions to create turbulence within the manure as it contacts the plates to disrupt bridging of manure over the auger.
