[0041] The pumping system 10 provided in this embodiment includes a water tank 110, a hopper 120, a delivery cylinder 130 and a plurality of tie rods 140. The delivery cylinder 130 is arranged between the hopper 120 and the water tank 110 for conveying concrete. The plurality of tie rods 140 are evenly arranged around the outer wall of the delivery cylinder 130. One end of each tie rod 140 is fixedly connected to the water tank 110, and the other end is fixedly connected to the hopper 120. The delivery cylinder 130 can be clamped between the water tank 110 and the hopper 120 by the plurality of tie rods 140, and the hopper 120, the water tank 110 and the delivery cylinder 130 are connected into a whole, so as to ensure the overall connection strength and ensure that the water tank 110 and the hopper 120 are evenly stressed, thereby reducing the failures such as the breakage of the tie rod 140 and the falling of the delivery cylinder 130, and enhancing the stability and reliability of the pumping system 10. The pull rod 140 includes a first connecting rod 142 and a second connecting rod 144, which are detachably connected and whose relative positions along the length direction are adjustable.

After completing one pumping, the distribution valve 200 switches, and the delivery cylinder 130 that is full of concrete starts pumping concrete, while the other delivery cylinder 130 sucks concrete from the hopper 120 at the same time. The two sets of pumping power devices pump and suck respectively, and so on, to achieve continuous pumping of concrete.

[0047] In some embodiments, the pumping system 10 also includes a stirring device 180, which is disposed in the hopper 120 and includes two sets of stirring blades.
