| Abstract: |
| Aiming at the problems of high labor intensity and low efficiency of manual operation of potato film seeding in dry farming areas of Northwest China, a potato film hole seeding machine with a duckbill forced opening structure and soil covering device was designed, and the structure and working principle of the whole machine were expounded. Combined with the agronomic requirements of potato film mulching planting, the structural design and parameter calculation of key working parts such as the hole planter, hole\|forming device, and soil\|covering device were completed. The motion simulation analysis of the dibbler was carried out by RecurDyn multi\|body dynamics software to explore the influence of characteristic parameter λ on the motion trajectory. The results showed that when the characteristic parameter λ> 1(ω=2.0 rad·s-1 ), the dibbler met the necessary operating conditions for ‘zero\|speed seeding’ on the membrane. The field verification test was carried out with the hole rate, the qualified rate of plant spacing, and the qualified rate of covering soil as the test indexes. It was found that when the forward speed of the seeder was 0.4~0.6 m·s-1, the hole rate of the seeder was 1.97%, the qualified rate of plant spacing was 91.80%, and the qualified rate of covering soil was 96.30%. All the indexes met the national and industry standards, which could meet the production needs of potato planting in the dry farming areas of northwest China. |
