Abstract:
A device for automatically preparing liquid feed stuff for piglets by mixing dry feed stuff with water, and feeding the liquid feed stuff to piglets, comprising:a warm water supply unit automatically heating fresh water to a predetermined temperature, thus preparing warm water prior to supplying the warm water;a dry feed stuff supply unit automatically supplying the dry feed stuff; anda mixing unit repeatedly receiving predetermined amounts of warm water and dry feed stuff from said warm water supply unit and said dry feed stuff supply unit under the control of a main controller at predetermined intervals prior to appropriately mixing the dry feed stuff with the warm water every time, thus forming liquid feed stuff prior to selectively supplying the liquid feed stuff to a plurality of feeding troughs for piglets;wherein said warm water supply unit comprises:a water tank provided with both a water inlet pipe and a warm water outlet pipe, said water inlet pipe being connected to a fresh water supply source and being selectively opened by a first solenoid valve, and said warm water outlet pipe extending to said mixing unit and being selectively opened by a second solenoid valve;a heater interiorly installed in said water tank so as to heat water in the water tank to a predetermined temperature;a temperature sensor mounted in said water tank and used for sensing the temperature of water in the water tank prior to selectively starting said heater to heat the water in the water tank; anda water level controller adapted for maintaining a predetermined water level in the water tank;wherein said water level controller comprises:a vertical rod connected to a float positioned inside the water tank; anda switch used for controlling said first solenoid valve of the water inlet pipe, said switch being provided on said water tank and having a push plate coupled to a top end of said vertical rod so that the top end of said vertical rod selectively presses or releases the push plate in accordance with a water level in the water tank, thus turning on or off said switch.
