[0034] As Figures 1 to 2 shown, the front side of the dump hopper 2 is inwardly contracted, and a dump port 3 is arranged at the contracted front side of the dump hopper 2. By setting the front side of the dump hopper 2 as a funnel shape and arranging the dump port 3 at the front end, the width of the dump port 3 is smaller than that of a conventional lifting hopper. When the feeding port of the concrete mixing station is small, the dump port 3 is used for dumping and feeding of the concrete aggregate, which can avoid the scattering of the aggregate during the dumping and feeding process, and is suitable for the concrete mixing station with a small feeding port. In addition, the small dump port 3 can make the dumping of the aggregate more concentrated, and reduce the smoke generated during the dumping process.
