[0002] With the rapid development of my country's construction, railways, highways, bridge construction, etc. all need pipe piles to lay the foundation, and the demand for pipe piles has greatly increased.
[0003] In the production process of concrete pipe piles, workers usually use a trolley to transport the mixed concrete to the concrete precast mold platform during the production process, and the workers use tools such as shovels to load the concrete into the precast mold.
[0004] Today's technical requirements are constantly improving. In order to meet users' needs for refined material distribution, gravity blanking and pump blanking are usually used. Gravity blanking is to use the concrete's own gravity to assist the vibration motor to blank the material. The blanking accuracy is low and the blanking speed is also very uncontrollable. Pump blanking is to transport and pour concrete along the delivery pipe through a concrete pump or pump truck. The manual operation of pumping is more complicated, and the use and maintenance costs are higher. Utility Model Content
