Pouring device for accelerating falling of concrete filled steel tube in vacuum

The utility model provides a pouring device for vacuum acceleration of falling of steel pipe concrete. The pouring device comprises a pouring mechanism and a vacuum acceleration mechanism. A pouring channel used for being communicated with the cavity of the steel pipe is formed in the pouring mechanism. The pouring mechanism is constructed to be capable of putting concrete into the hopper and pouring the concrete into the cavity of the steel pipe through the pouring channel. And a plurality of first air exhaust holes are further formed in the pouring mechanism. The vacuum acceleration mechanism comprises a vacuum pump and an exhaust pipe. The exhaust pipe is further provided with a plurality of second exhaust holes corresponding to the first exhaust holes, and the second exhaust holes are communicated with the first exhaust holes corresponding to the second exhaust holes. The pouring device is high in practicability, corresponding blanking structures with different shapes and calibers can be flexibly selected
