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