Description

Technical Field

[0001] The invention belongs to the field of concrete production, and in particular to a concrete mixing station unloading system and method. Background Art

[0002] Small and medium-sized PC production lines generally use torpedo tankers as concrete transportation equipment, which has the advantages of being fast and efficient. They generally use steel overhead walkways from under the mixing station hopper to above the working surface of the PC production line. After unloading into the receiving hopper of a professional placing machine, they quickly return to the mixing station for reloading.

[0003] The mixing station of a professional PC production line is only equipped with a single discharge port. If you want to load both the elevated torpedo tanker and the concrete mixer truck (mostly used for nomadic PC production outside the factory), you need to install a material distribution device at the mixing station discharge port; the existing material distribution device includes a herringbone forked discharge port, a vertical mixer with two discharge ports, and a rotatable inclined chute. Before installing the material distribution device, the height of the mixing station needs to be increased, and the distance between the discharge port and the ground needs to be increased to ensure the normal loading of the torpedo tanker and the concrete mixer truck. It cannot be used to modify the mixing station of the existing PC production line. Therefore, how to make a concrete mixing station unloading system and method that can solve the existing technical problems has become a technical problem to be solved. Summary of the invention
