山区烤烟液肥深施机的设计
|
摘要
针对贵州山区烤烟液肥施肥机械化水平不高、液肥浅施及施肥不均等因素带来的问题,设计了一款适合在山区复杂地形下使用的烤烟液肥深施机,采用深施方式,提高了液肥施用效率,实现了精准变量施肥。分别对肥液供给装置、田间自适应调节装置、施肥枪及其变量控制系统进行了设计,并对整机受力杆件进行有限元分析。试验结果表明:山区烤烟液肥深施机施肥精度可达95. 3%,施肥误差控制在4. 7%以内,符合烟草行业的农艺要求。该机结构设计合理,可为山区烤烟液肥施肥作业提供技术参考。
Guizhou mountainous area,the author of this paper flue-cured tobacco mechanization level is not high,the effects of fertilization effects of shallow problem with inequality and fertilizer factors,designed a model suitable for complex terrain in the mountains of flue-cured tobacco effects of deep machine,adopting deep way,improve the efficiency of the effects of fertilization,precision variable fertilization. This machine designs the fertilizer and liquid supply device,the field adaptive adjusting device,the fertilizer gun and its variable control system respectively,and carries on the finite element analysis to the force bar parts of the whole machine. The experimental results show that the fertilization accuracy of the deep applicator of flue-cured tobacco fertilizer in mountainous areas can reach 95. 3%,and the fertilization error can be controlled within 4. 7%,which is in line with the agricultural requirements of the tobacco industry. The structure design of this machine is reasonable,which provides a technical reference for applying fertilizer in flue-cured tobacco liquid fertilizer in mountainous area.
