Leakage-proof ear box for grain unloading

The ear box comprises a box body with an opening in the top, an unloading guide groove is formed in the top of a side plate of the box body, a harvesting and feeding opening is formed in the top of the side plate, adjacent to the unloading guide groove, of the box body, a baffle plate is arranged between the harvesting and feeding opening and the unloading guide groove, and an ear baffle is arranged at the top of the baffle plate. And the baffle plate and the ear baffle plate are partially overlapped with the side plate of the grain unloading guide groove. According to the utility model, the baffle plate can effectively prevent grains or clusters close to one side of the harvesting feeding port in the box body from falling off; the ear baffle can effectively prevent grains or ears from falling off from the transition position of the grain unloading guide groove and the harvesting inlet when the grains or the ears are poured to the grain unloading guide groove. Furthermore, the grain unloading guide groove is
