The utility model discloses a concrete hopper capable of preventing large materials from entering, which comprises a hopper body and further comprises a support fixed on the upper edge of the hopper body, and the lower end of the support is connected with the hopper body. The two sides of the anti-falling fence are connected with the support, the outer edge of the anti-falling fence is connected with the upper edge of the hopper body, the inner edge or the inner end of the anti-falling fence is not lower than the outer edge, and the orthographic projection area of the anti-falling fence at the feeding port of the hopper body accounts for 1 / 4-1 / 3 of the area of the feeding port. The anti-falling fence is arranged to prevent large materials from entering, and the phenomenon that a guide pipe is blocked due to the fact that large concrete blocks exist can be effectively reduced.
