Large-span tower main pipe concrete pouring mechanism and pouring system thereof

The utility model relates to the technical field of large-span tower main pipe concrete pouring, and discloses a large-span tower main pipe concrete pouring mechanism and a pouring system of the large-span tower main pipe concrete pouring mechanism. And the two hoppers are respectively arranged below the two rocker arms of the double-flat-arm holding pole and are respectively connected with the suspension steel wire ropes on the two rocker arms. The two hoppers are connected with the suspension steel wire ropes on the two rocker arms of the double-flat-arm derrick, the two hoppers are lifted, so that the material ports of the hoppers are connected with the pouring port of the large-span main pipe, and the electric valve can control the flow speed of concrete in the two hoppers. According to the situation of concrete in the two hoppers, the opening degrees of the two electric valves are adjusted correspondingly to guarantee stress balance of the two rocker arms, then the stability of the double-flat-arm derric
