Cordyceps sinensis selenium-rich pig feed feeding device

The utility model discloses a cordyceps sinensis selenium-enriched pig feed feeding device which structurally comprises a metering mechanism and a mixing mechanism, feed and water are poured into a stirring box through a feeding port, and a servo motor drives a rotating shaft to enable a stirring roller to conduct stirring. Then, a rotating motor drives a rotating shaft to enable a guide shaft at the lower end to introduce the feed into the weighing box, after continuous discharging till a set range is reached, a pressure sensor controls the rotating motor to stop working, an electromagnetic valve is opened to enable the feed to be input into a feed trough through a discharge port, and then the work is repeated; the problems that when existing cordyceps sinensis selenium-rich pigs are fed, pig feed is manually poured into a stirring box to be stirred and then poured into a feeding trough, the feeding amount cannot be controlled, and consequently the feed is wasted and deteriorated due to too much feeding, or
