In the concrete pumping system 200 according to the present invention, the first delivery cylinder 210 is disposed corresponding to the first stirring device 110, the second delivery cylinder 220 is disposed corresponding to the second stirring device 130, that is, the first delivery cylinder 210 is fed by the first stirring device 110, the second delivery cylinder 220 is fed by the second stirring device 130, the first delivery cylinder 210 and the second delivery cylinder 220 alternately suck and feed, and the delivery pipe 230 is connected to both the first delivery cylinder 210 and the second delivery cylinder 220 in a switching manner, so that the delivery pipe 230 is always connected to the delivery cylinder that performs feeding, and the delivery cylinder that does not perform feeding is sucking, so that the suction speed can be ensured and energy can be saved according to the connection state adjustment of the delivery pipe 230 to the first delivery cylinder 210 and the second delivery cylinder 220, and since the stirring system 100 according to any of the above embodiments is included, the stirring system 100 according to any of the above embodiments has all the advantages of the stirring system 100 according to any of the above embodiments, this is not mentioned here.

Specifically, a comparison relation database of the rotation speed and the operation speed can be preset, and the rotation speed is determined according to the operation speed.
When the concrete mixer is used, the first motor 112 is driven (in a hydraulic mode, an electric mode, a pneumatic mode and the like) to work to drive the first stirring shaft 120 to rotate, so that the first stirring blades 122 are driven to rotate, and in the rotating process, concrete around the first stirring blades 122 is sent to the opening part of the first conveying cylinder 210, so that the concrete can be conveniently sucked into the first conveying cylinder 210.

As shown in fig. 2, for example: the first conveying cylinder 210 is a material suction side conveying cylinder, and a proper stirring speed is required to push the concrete in the hopper 150 to the mouth of the first conveying cylinder 210, so that the suction of the material is ensured; at this time, the speed of the first stirring blade 122 can be matched through the system of the controller, and the controller is controlled to operate at the optimal rotating speed; for the second delivery cylinder 220 on the pushing side on the other side, the mouth of the second delivery cylinder 220 is not connected to the hopper 150, and the concrete in the hopper 150 in the region does not need to be stirred or rotated at a low speed, even stopped, so as to save energy. Of course, the stirring speed of the second stirring blade 142 needs to be individually controlled by the controller. On the contrary, when the direction of the delivery pipe 230(S pipe) is changed, the suction state of the concrete under the second mixing blade 142 and the first mixing blade 122 is changed, and the mixing rotation speed also needs to be separately adjusted.
The speed of the first stirring blade 122 and the speed of the second stirring blade 142 on the left side and the right side are independently controlled by the central controller, so that the high-efficiency material suction on the material suction side is achieved, and energy conservation is realized simultaneously under the condition that the idle rotation on the material suction side is ensured not to be isolated.
