Abstract

The utility model provides a semi-open type blanking hopper which is communicated with a discharge port arranged on a stirring device and comprises a temporary storage hopper, a feed port and a discharge port are respectively arranged at the top end and the bottom end of the temporary storage hopper, the feed port covers the outer side of the discharge port of the stirring device and is fixedly connected with the stirring device, and the discharge port of the temporary storage hopper is fixedly connected with the discharge port of the stirring device. A discharging assembly is arranged at the bottom end of the discharging port in a sliding mode, and a power part used for driving the discharging assembly to move in the direction close to or away from the discharging port is arranged on one side of the discharging port. According to the semi-open type discharging hopper, the semi-open type discharging hopper can better adapt to upgrading of stirring equipment, production cost is greatly reduced, uniformity and stability of concrete discharging are achieved by accurately controlling movement of the discharging assembly, the problems of uneven discharging, unstable discharging speed and the like are solved, and the discharging efficiency is improved. Therefore, the production efficiency of the concrete is improved.
