摘要
针对肉苁蓉产业化发展对机械播种装备的需求,以提高肉苁蓉接种效率、降低劳动强度,实现肉苁蓉机械化、规模化种植为目的,研制了一种基于液体施种的肉苁蓉接种机。对样机关键部件进行了分析与设计,确定了链式开沟、接种、覆土等装置的结构及工作参数,解析了核心部件作业机理,并进行了初步试验。结果表明,当拖拉机行走速度为340 m·h^-1、动力输出轴转速为540 r·min^-1、喷种泵压力0.2 MPa时,测得开沟深度为50 cm、开沟宽度为30 cm时,喷种覆盖面宽度4 cm,可满足肉苁蓉的播种农艺要求,且开沟、接种效果良好,覆土平整,能够实现机械化接种。
Aiming at the demand for mechanical seeding equipment for the industrialization of Cistanche deserticola and in order to improve the efficiency of Cistanche deserticola inoculation,reduce labor intensity,and achieve the purpose of mechanized and large-scale planting of Cistanche deserticola,a Cistanche deserticola seeding machine based on liquid seeding was developed,and a prototype test was carried out.The key components of the prototype are analyzed and designed.The structure and working parameters of the chain opener,inoculation,and soil covering device were determined.The operation mechanism of the core components was analyzed and the preliminary test was carried out.The results showed that when the tractor walking speed was 340 m·h^-1,the power output shaft speed was 540 r·min^-1,the seed pump pressure was 0.2 MPa,the furrow depth was 50 cm,the furrow width was 30 cm,and the seed spraying coverage width was 4 cm,which could meet the agronomic requirements of Cistanche deserticola.The effect of ditching and inoculation was good,and the covering soil was flat,which can realize mechanized inoculation.
