The utility model relates to an automatic feeding of breeding pig is eaten and pig house cleaning device, install pressure sensor at the pig inslot, when the food of pig inslot reduces to the schwellenwert, pressure sensor arrives the hypotony, transfer the singlechip with the signal, single chip microcomputer control feeding valve and outlet valve door are opened, through inlet pipe and inlet tube with fodder and water joining agitator, install level sensor in the stirring storehouse, feeding valve and inlet valve close when the liquid level increases to the setting value, agitator motor drives the beater mill, one fixes time afterwards, it opens to go into channel valve, through going into the food inflow pig inslot that the barrel will stir, the groove for there being the slope can be established in the pig groove, it flows in to be convenient for food, install the shower nozzle device above the pig house, the shower nozzle can be sprayed water once at set intervals to the debris such as excrement and urine that will wash away are in the spout of the slope is taken in pig house groove inflow, and the spout below links firmly an unloading pipe, and the fermentation vat is gone into through the unloading duct flow to debris such as the excrement and urine that washes away. The device is can not only be unmanned the time automatic timely to be added food to the pig groove and can also clear up the pig house, has guaranteed the food supply and the interior cleaning work of pig house of pig, has realized the intellectuality.
