Ball arching device for promoting motion of pigs

A ball arching device for promoting pig movement comprises a base, a supporting column fixedly installed on the base, a rotating column rotatably installed at the upper end of the supporting column and a feed trough fixedly installed on the rotating column, and is characterized in that a plurality of supporting shaft pipes are rotatably installed on the periphery of the rotating column, and swing arm pipes are fixedly installed at the outer ends of the supporting shaft pipes respectively; and a plurality of discharge holes are formed in the lower part of the feed trough. The device is simple in structure and ingenious in conception, feed particles are placed in the spherical shell, pigs can be guided to arch the spherical shell, so that the spherical shell swings up and down, the feed particles are discharged from the discharge holes for the pigs to eat, and when the pigs arch the spherical shell, pig noses can be exercised continuously, so that the meat quality of the pig noses is improved, and meanwhile, pi
