Anti-winding feeding device of sweet potato harvester

The utility model relates to the technical field of agricultural machinery, in particular to an anti-winding feeding device of a sweet potato harvester, which comprises a feeding box, a grain pulling box is arranged on the left side of the feeding box, a first transmission box is fixedly mounted on the front side of the feeding box, and a second transmission box is fixedly mounted at the top of the grain pulling box. And a working mechanism is arranged in the feeding box. According to the anti-winding type feeding device of the sweet potato harvester, twisting teeth are arranged on the surface of a twisting plate, when a first rotating shaft rotates to drive a twisting barrel to rotate, due to the fact that sweet potatoes are dragged by the twisting plate to rotate, stalks of the sweet potatoes are twisted off by the twisting teeth in the rotating process, and therefore the problem that the sweet potatoes are wound on the surface of the first rotating shaft to cause jamming is solved; the problems that the li
