丘陵山区电动井窖式烟草移栽机设计与试验

结合烟草小苗移栽的农艺要求,设计一种适用于丘陵山区的电动井窖式烟草移栽机,整机具备机械化井窖成穴、投苗和浇水等小苗移栽作业能力。在完成移栽机的挖穴装置、投苗装置和浇水装置等关键零部件模块化设计和组装后进行田间试验。试验结果表明,井窖式烟草移栽机的作业效率为0.402hm2^/天,井窖成穴合格率＞90.8%,移栽作业合格率＞87.7%,满足丘陵山区烟草井窖式移栽的农业要求,为丘陵山区烟草小苗井窖式移栽技术的推广应用提供装备支撑。

Design and experiment of electric well cellar tobacco transplanting machine in hilly and mountainous areas

Combined with the agronomic requirements of tobacco seedling transplanting, an electric well cellar tobacco transplanting machine suitable for hilly and mountainous areas was designed. The whole machine has the ability of mechanized well cellar hole forming, seedling throwing and watering. After completing the modular design and assembly of key parts such as digging device, seedling throwing device and watering device of transplanting machine, the field experiment was carried out. The test results showed that the operation efficiency of the well-cellar tobacco transplanting machine was 0.402 hm2 / day, the qualified rate of the well-cellar was more than 90.8 %, and the qualified rate of transplanting operation was more than 87.7 %, which met the agricultural requirements of the well-cellar transplanting of tobacco in hilly and mountainous areas, and provided equipment support for the popularization and application of the well-cellar transplanting technology of tobacco seedlings in hilly and mountainous areas.
