Research on the Structure of an Underground Irrigation Composite Pipe-Forming Device

In order to promote the comprehensive utilization of corn straw and development field water-saving irrigation technologies, a kind underground composite pipe-forming device mixed with soil extrusion molding was designed. The key extrusion-forming components affecting forming rate pipe were optimized by taking diameter winch blade, shaft winch, pitch as variables output power test indices. best structural parameters obtained using weight normalization method; blade 430 mm, 86 387 1.37 kg/s, increased 41%. Field tests conducted verify simulation results, relative error between value 5.88%, which verified reliability test. average density extruded tube 1.92 g/cm3, meeting requirements for formation.
