A pipe pile concrete placing machine

technical field

The utility model relates to the field of building material production equipment, in particular to a pipe pile concrete placing machine.

Background technique

With the rapid development of construction in my country, railways, highways, bridges, etc. all need pipe piles to lay the foundation, and the demand for pipe piles has greatly increased.

Concrete placing machine is used as equipment for forming concrete pipe piles in construction industrialization. Its function is to send the concrete through the pipeline to the pipe pile mold for pouring the pipe pile, and then use the pipe pile mold to compact and centrifuge the concrete to form the concrete pipe pile. Usually, a hopper is set at the bottom of the concrete placing machine to collect concrete to prevent the concrete from being excessively spilled to the outside of the mold. After the discharge of the hopper, due to the viscosity of the concrete, the inner surface of the hopper usually adheres to a lot of concrete. If it is not cleaned in time, the outlet of the hopper will be narrowed after the concrete solidifies, which will lead to the next time when the placing machine is used for distribution. , the blanking speed of the sink hopper decreases.

In the prior art, the Chinese patent with the authorization announcement number CN207959967U discloses a concrete placing machine, which includes a hopper provided with a discharge port, a walking frame used to support the hopper, and a casting member arranged at the bottom of the hopper for receiving materials. .
