The invention provides a culture feeding machine. The culture feeding machine comprises a feeding device, a sealing device, vibrating devices, a gas blowout system and a time control device; a sealing cover is arranged at the upper part of the culture feeding machine; vibrating motors are mounted on internal walls of a storage bin of the device; a gas blowout device is mounted on a blow pipe at the lower end of the culture feeding machine and uses a gas pump to supply gas, and the gas drives an internal rotor to rotate; and a time controller can simultaneously control the on-off of the gas pump and the vibrating motors according to a time schedule. According to the culture feeding machine, the smoothness of feeding can be guaranteed, and the vibrating motors mounted on the internal walls of the storage bin can drive the whole device to vibrate together so as to prevent feed from caking; and the gas blowout device mounted on the blow pipe can give a certain initial speed to the fed feed, and then, convenience is provided for control on the water depth and direction of feeding, so that due to the vibrating motors and the gas blowout device, which are mounted additionally, the work efficiency is increased, the technical implementation is simple, and meanwhile, a good feeding effect can be achieved.
