Design and experiment of wheat multi-level ballast control sowing monomer
Journal Title: Journal of Henan Agricultural University - Year 2024, Vol 58, Issue 6
Abstract
[Objective] In order to solve the problem of uneven sowing of wheat seeds and unreal soil suppression caused by the change of soil conditions in the Huang-Huai-Hai region of China, a multilevel suppression device for wheat profiling seeding monomer was designed based on the principle of suppressive sowing of wheat wide seedling belt seed furrow. [Method] Through the analysis of the overall force of the profiling seeding monomer and the coupling simulation of EDEM-Recurdyn, the ballast pressure range of the sowing seed ditch was obtained as 100~300 N. According to the soil groove test based on the Box-Behnken experimental design method, the quadratic multinomial regression model of the key parameters of the multi-level compression device of wheat sowing monomer was established. [Result] The results show that the soil bulk density before sowing were 0.97、1.12、1.25、1.35 and 1.41 g·cm-3, and the ballast pressures were 300, 250, 210, 150 and 100 N, respectively. Under the optimal combination of parameters, the soil bulk density was stable at 1.3~1.4 g·cm-3 and the average pass rate of sowing depth was 96.64%, which significantly improved the seed bed conditions and the sowing quality. [Conclusion] The multi-level ballast control sowing monomer of wheat can meet the needs of sowing operations in the Huang-Huai-Hai region, and can provide equipment support and technical reference for wheat sowing in the Huang-Huai-Hai region of China.
