[0002] In the pile raft foundation construction of high-rise and super high-rise buildings, especially in the pile foundation construction of bored piles, a mud pump is needed to pump a large amount of mud produced by drilling into a mud pool. The mud production rate is different at different construction stages, such as low mud production rate at the initial drilling stage and layer changing, and high mud production rate at normal drilling. Therefore, it is necessary to adjust the mud pumping rate to ensure normal construction. In addition, in the scenes involving mud transportation such as river dredging and mine tailings treatment, it is also necessary to adjust the mud pumping rate according to the actual working conditions.

[0003] In the traditional mud pumping process, the mud pump has deficiencies in adjusting the mud flow rate.

[0033] By adopting the above technical scheme, when the rate is adjusted, the arc-shaped baffles 36 are controlled to slide with the mud outlet pipe 37 through the telescopic cylinder 33, the flow area of the mud outlet pipe 37 can be accurately adjusted, and the flow rate of the mud can be flexibly changed to adapt to different working requirements.

[0034] In the embodiment, one side of the valve body 21 is fixedly connected with a valve cover 22, the other side of the valve cover 22 is provided with a rotary fixing seat 23, and the rotary fixing seat 23 and the valve cover 22 are rotatably connected with a valve rod 25.
