Claims

[Scope of utility model registration request]

a sealed cylindrical fixed casing having an axis that intersects with the axis of the water pipe system and communicating with the water pipe; and a fixed casing fitted to the fixed casing so as to be axially movable;
and a transfer piston provided with a space for accommodating garbage sent from a garbage carrying machine installed by opening a part of the fixed casing, and a stroke rear end position of the transfer piston where the accommodating space faces and communicates with the opening. A garbage pumping device comprising a drive source that moves forward and backward with a stroke amount corresponding to the front end position of the stroke that crosses the axis of the water pipe system,
Partition walls are formed in the axial direction front and rear of the housing space, the outer peripheral portions of which slide in liquid-tight contact with the inner surface of the fixed casing, and these partition walls have small drainage gaps spaced apart from the inner surface of the fixed casing. They are connected to each other by at least one connecting plate extending in the axial direction, and when the transfer piston is at the rear end position of the stroke, a portion of the fixed casing opposite to the connecting plate has a width larger than the width of the connecting plate. A drainage structure for a garbage pumping device characterized by having a small-diameter drainage hole formed therein.
