气吹式大豆精量播种机的设计

Design of air blown soybean precision planter

根据大豆种植的农艺要求，设计了气吹式大豆精量播种机。该机作业速度可达6-8km／h，采用三点悬挂式挂接形式，配套动力为88～103kW，可以一次性完成开沟、施肥、播种、覆土、镇压等多项作业，并且能够做到侧深施肥和精密播种。实践表明，该机结构设计合理，性能可靠，能够满足农业技术的要求。

Designed according to the soybean agronomic requirements, the machine articulated in three-point suspension, which operating speed is 6 - 8km/h with supporting power 120 to 140 horsepower. The operation of ditching, fertilizing, sowing, covering earth, rolling and many others can be once completed, and even the deep side fertilizing and precision seeding can be done by it. Practice shows the machine＇s structure is reasonable and performance is reliable to meet the requirements of agricultural technology.
