In this embodiment, the discharge port 112 can be completely sealed by the sealing device 120, so that the purpose of no material leakage during transportation is achieved, and the environmental protection performance is improved. Because the feeding structure and the feeding small cone structure in the mixing drum are removed at the discharge hole 112, the weight of the whole vehicle is reduced. Meanwhile, the feeding hole 132 of the feeding device 130 is moved upwards to the side wall 114 of the cylinder body 110, so that the loading capacity of the mixing drum 100 is improved.

To sum up, according to the utility model discloses a beneficial effect of embodiment does:

1. the discharge port 112 is completely and effectively sealed by the sealing device 120, so that material leakage of the mixing drum 100 in the transportation process is avoided.

2. The feeding device 130 is arranged on the side wall 114, so that the feeding device 130 can be positioned above the cylinder 110 along with the rotation of the cylinder 110, the structure of the feeding device 130 is simplified, the effect of reducing the overall weight of the mixing drum 100 is achieved, and the feeding hole 132 is positioned outside the cylinder 110, so that the load capacity of the cylinder 110 is improved.
