The utility model provides a volume of feeding, bitonic section formula of distance of feeding are spouted and are shone machine of feeding belongs to the quick -witted field of feeding. Including the frame, the frame bottom is equipped with maintains the stable supporting leg of frame and drives the gyro wheel that the frame removed, is equipped with power device on the frame, and power device is connected with the fan to drive fan work, the air exit of fan are connected to the Y -pipe way, and the other end that Y -pipe said is connected to the discharge gate of storage silo through the unloading video disc, and the last one end that Y -pipe said is as the output. The volume of throwing something and feeding of unloading video disc and the clearance of unloading pipe guaranteeing bait is adjusted through the unloading control valve to the adjustable machine of feeding, and the distance of throwing something and feeding of power control valve regulation bait satisfies the linkage of the controllable volume of throwing something and feeding and the distance of throwing something and feeding simultaneously and adjusts.
