The utility model discloses a feed stirring tank. The device comprises a grinding chamber and a stirring chamber, a first motor is fixed at the top of the grinding chamber; the output end of the firstmotor is rotationally connected with a first rotating shaft; the first rotating shaft is connected with a roller shaft through a transmission belt; the outer surface of the roller shaft is sleeved with a grinding roller; a feeding opening is formed in one side of the grinding chamber in a penetrating manner; the feed stirring tank is provided with a grinding roller and a cutting rod, when the feed enters through the feed inlet; the first motor is operated by controlling the operation table; the first rotating shaft can rotate to drive the transmission belt to rotate; the grinding roller connected with the transmission belt rotates; due to the fact that the two grinding rollers are meshed with each other, when feed enters, the grinding roller located below one side of the feeding port grinds the feed, meanwhile, a second motor is started to operate by controlling the operation table, a second rotating shaft rotates to drive a cutting rod to rotate, and in the falling process after thefeed is ground in the feed, the feed can be quickly cut more thoroughly by the cutting rod.
