Novel hog house feces drain mechanism

An objective of the invention is to provide a novel hog house feces drain mechanism. The novel hog house feces drain mechanism comprises feces drain channels, a urine drain trench, and a feces drain trench. The feces drain channels are arranged under a mesh bed hog house, and is arranged according to pigsty layout in the mesh bed hog house. The cross section of the feces drain channel is in a structure of V shape or a U shape which is higher on two sides and lower in the middle. The urine drain trench and the feces drain trench are respectively arranged on two ends of the longitudinal direction of the feces drain channel. The end of the feces drain channel on the urine drain trench is lower than the end on the feces drain trench. The novel hog house feces drain mechanism can conveniently separate pig manure and pig urine, and feces drain efficiency is high. The mechanism can further improve culture environment of hog houses.
