| 摘要 |
The adapter for the liquid manure vacuum agitator of the present invention comprises an elongated cylindrical tubular member having opposite ends and an internal annular bore defined by the interior cylindrical wall of the tubular member. A continuous spiraling blade is attached to the interior of the cylindrical wall, the blade having sufficient width to extend partially radially inwardly to terminate in an inner end which is spaced axially outwardly from the centerline of the tubular member, thereby giving an open center through the tubular member along the longitudinal centerline thereof. The spiraling blade causes agitation of the manure as it is forced through the tube.
