The utility model relates to the field of a concrete mixing plant, and in particular relates to a concrete discharge hopper and a hopper body thereof. The concrete discharge hopper comprises a hopper body and a hopper door, wherein a ring-shaped material collecting clamp slot which surrounds the discharge port of the hopper body is formed in the inner side of the hopper body. When being used for the first time, the concretes falling into the hopper body from the upper side are collected into the material collecting clamp slot; after being used for multiple times, the concretes in the material collecting clamp slot gradually deposit on the inclined inner wall of the hopper body, consequently a concrete lining; once the concrete lining is formed, the concretes falling into the hopper body in a subsequent using process directly strike the concrete lining, so as to prevent the hopper from being worn or damaged; because the concrete lining is a naturally formed structure and is not required to be repaired, the maintaining cost of the concrete hopper is also reduced, in conclusion, by utilizing the concrete discharge hopper, the problems that the concrete discharge hopper for the concrete mixing plant is easily worn and the maintaining cost is high are solved.
