Each part will be described in detail below.

In particular, the running means 2 is arranged on the frame 1 and runs along an X-direction running track (not shown in the figures) for driving the frame 1 in motion relative to the stationary pipe mould. The running rail can be erected in the air, and the rack is arranged on the running rail through the running device and driven by the running device to run, and the mode is adopted in the embodiment. The running track can also be laid on the ground, the frame extends downwards, and the part of the frame close to the ground is arranged on the running track through the running device and is driven by the running device to run. The walking device and the walking track are driven by a motor and a gear, and are meshed with the rack to realize a walking mode. In other embodiments, the pipe die feeding system may also be stationary, and the pipe die moves relative to the pipe die feeding system to realize feeding, at this time, the pipe die feeding system is fixed on the ground through the frame, and the traveling device is not arranged on the pipe die feeding system, but is used for driving the pipe die to convey along the X-direction traveling track. In any way, the relative movement of the pipe die feeding system and the pipe die can be realized.

The weighing device 31 comprises four load cells, and the hopper is arranged at the upper part of the frame through the four load cells. Before feeding, firstly fill the hopper with concrete, the hopper continuously pours the concrete downwards into the pipe die along with the movement process of the frame, the weight of the hopper is gradually reduced, and the reduced weight is the weight of the poured concrete. The control device is respectively electrically connected with the weighing sensor and the walking device, obtains a real-time weight signal sent by the weighing sensor, and calculates and obtains the weight loss of the hopper in unit time, namely the weight loss rate of the hopper, wherein the weight loss rate is the feeding rate of concrete. Even if the size of the structure influencing the feeding speed such as the outlet of the hopper is completely unchanged, the concrete mostly has caking problems of different degrees due to the influence of the material characteristics of the concrete and the specific state during feeding, and the concrete is not discharged in a completely uniform state during downward pouring, so that the situation that the material is excessively discharged and the material is insufficiently discharged sometimes exists, namely the weight reduction speed is not a constant value but changes along with the time. Recording the walking speed of a pipe die feeding system driven by the walking device, namely the hopper, wherein in order to ensure more uniform feeding, the control device is configured to adjust the walking speed according to the weight loss rate and output a walking speed control signal to the walking device, thereby controlling the running speed of a motor in the walking device. For example, a large weight reduction rate at one moment means that the blanking is excessive, and at this moment, the control device controls the walking speed to be accelerated, while a small weight reduction rate at another moment means that the blanking is insufficient, and at this moment, the control device controls the walking speed to be accelerated. Therefore, the feeding weight of the concrete in unit length of the pipe die can be kept constant, so that uniform feeding is realized, and the influence of the material characteristics and the specific state of the concrete on the feeding uniformity is reduced to the greatest extent.
