Rolling ball device for promoting movement of pigs

A rolling ball device for promoting pigs to move comprises a rolling ball shell, a storage bin is fixedly installed in the rolling ball shell, and the rolling ball device is characterized in that a vertical pipe is fixedly arranged in the storage bin, the inner end of the vertical pipe is communicated with the interior of the storage bin and fixedly connected with the bottom of the storage bin, and a plurality of feeding holes are formed in the inner end of the periphery of the vertical pipe; the interior of the vertical pipe communicates with the interior of the storage bin through the discharging hole, and feed particles in the storage bin can enter the vertical pipe through the feeding hole. The pig rolling ball is simple in structure and ingenious in conception, feed particles are arranged in the rolling ball shell and spread out through rolling of the rolling ball shell, the more the feed particles roll, the more the feed is spread out, so that pigs are guided to do rolling ball movement, meanwhile, the
