The invention provides a feed processing and producing feeding device. The feed processing and producing feeding device is mainly used for the field of feed processing and producing. The feed processing and producing feeding device comprises a base plate, a support, a conveying pipe, feeding buckets, a mixing bucket and universal wheels. The support is arranged on the upper surface of the base plate, the conveying pipe is arranged in the support, the three feeding buckets are arranged on the upper surface of the support and include two large-material buckets and one small-material bucket, a conveying device is arranged inside the conveying pipe, the tail end of the conveying pipe is bent downwards and connected with the mixing bucket, and the lockable universal wheels are arranged on the lower surface of the base plate. According to the feed processing and producing feeding device, multiple materials can be fed at the same time; in addition, it can be avoided that in the feeding process, dust in smashed materials floats around, and the environment is polluted, and the body health of an operator cannot be affected; as a mesh screen is additionally arranged in the device, large-particle substances which do not meet requirements can be removed; after a vibration exciter is additionally arranged, the pipe can be prevented from being blocked in the conveying process; as the small-material bucket is arranged, small materials can be added while large materials are added, feeding time is saved, and feeding difficulty is lowered.
