This invention discloses a retractable multi-material 3D printing head, which includes an extrusion structure, a first feeding structure, a second feeding structure, and a third feeding structure. By connecting the three feeding structures with one extrusion structure, the extrusion retraction problem in 3D printing of multiple materials is solved. The extrusion structure has three meshing screws, resulting in high mixing efficiency during slurry mixing. Simultaneously, each of the three feeding structures has a screw, allowing for better control of the amount of high-viscosity material added to the extrusion structure. Furthermore, the three screws inside the extrusion structure are specially designed irregular-shaped screws. While achieving conventional mixing, they not only better control the material extrusion amount but also work together with the screws in the feeding structures to achieve slurry retraction when printing high-viscosity materials, improving the forming effect and allowing for a wider solid content range in the formed ceramic slurry.

This invention relates to the field of snail farming, specifically disclosing a high-density, factory-style snail farming equipment, including a rootless duckweed farming pond and a snail farming pond. The rootless duckweed farming pond is higher than the snail farming pond. It also includes a water circulation mechanism, a partition mechanism, and a solid waste collection mechanism. The water circulation mechanism is located on the rootless duckweed farming pond and the snail farming pond. The partition mechanism is located at the top of the snail farming pond, and the solid waste collection mechanism is located at the bottom of the snail farming pond. The solid waste collection mechanism, with its bottom slag hopper and transparent collection tank, can collect solid waste from the snail farming pond. Furthermore, the pipes installed through the water circulation mechanism maintain water flow within the snail farming pond, facilitating the dispersion of snail feed and oxygen. Simultaneously, the first and second plates of the partition mechanism within the snail farming pond provide space for snails to crawl and move, effectively improving the yield and quality of snail farming.
