Design and experimental study of 2BMYDF-2/4 soybean and corn high-density planting and separate controlled fertilization seeding machine
To solve the problem of low mechanization level and poor compatibility of equipment in soybean-corn intercropping,a soybean-corn dense planting and controlled fertilization seeding machine was design and produce,which could complete the following operations in one pass:rotary tillage,soil crumbling,furrowing,fertilization,seeding,soil covering and soil compaction.First,based on the intercropping agricultural requirements,the overall design scheme of the 2BMYDF-2/4 type dense planting and controlled fertilization seeding machine for soybean-corn intercropping was proposed.Then,the key components,such as the soil crumbling and furrowing device,the four-bar linkage profiling device,the finger-type seed dispenser,and the transmission structure,were designed,the parameters were optimized,and the key parameters were determined.Finally,a seeding experiment was conducted in Yuji Town,Dongchangfu District,Liaocheng City.The results showed that when the seeding and fertilization working speed was 6.4 km/h,the index of soybean and corn seed spacing,repeated sowing,seeding failure rate,seeding depth,and seed damage rate were 94.3%and 86.4%,1.3%and 6.2%,0.6%and 2.4%,90.3%and 90.7%,0.32%and 0.26%.The machine's performance indicators could meet the agricultural requirements of soybean-corn intercropping to a satisfactory degree.
