ABSTRACT:
A manure pit extends the length of a swine confinement building and includes access openings through an outside wall extending inwardly and downwardly toward the center of the pit to receive a stirring device mounted on a cart for being moved between the access openings. The stirring device includes an axial shaft in an elongated tube provided with inlet openings at the upper end of the tube for receiving liquid which is directed downwardly by propellers progressively increasing in number and volume capacity towards the bottom of the tube where it is discharged to a single outlet opening by a turbine pump. The pump includes paddles having leading edges facing in the direction of rotation of the shaft and trailing edges facing in the opposite direction. A convex upwardly bottom end plate directs the fluid radially outwardly through the outlet opening.
