[0002] Concrete pump, also known as concrete pump, consists of a pump body and a delivery pipe. It is a machine that uses pressure to continuously transport concrete along the pipeline. It is mainly used in building construction, bridge and tunnel construction. It is mainly divided into gate valve concrete pump and S valve concrete pump. During its working process, it can effectively use the piston movement in the hydraulic pipeline to form intermittent reciprocating impact force to pressurize the mud. The pressurized mud can overcome gravity and air pressure, realize a certain degree of mud transportation, and overcome the limitations of height and space. Therefore, it is widely used in construction occasions.

The utility model includes a transition bucket installed between the concrete pump truck hopper and the concrete transfer truck outlet, the transition bucket includes an outer bucket body and an inner bucket, the depth of the inner bucket is greater than the depth of the outer bucket body to form an overflow, and the outer bucket body and the inner bucket bottom are provided with discharge ports of the same shape and size, and the inner hopper is provided with a lifting hole to connect the lifting device. The advantage is: using the overflow form, the flow rate can be adjusted in both directions, thereby forming a stable mud discharge, protecting the body safety of the concrete pump truck and the feeding pressure of the pipeline.

In the above design, the material is discharged through the discharge ports at the bottom of the outer hopper body and the inner hopper, but the diameter of the discharge port is fixed. Although the material can be discharged stably, the discharge amount cannot be adjusted according to demand, which is not conducive to protecting the safety of the concrete pump truck body and the feeding pressure of the pipeline, and the use effect is poor.
