| 摘 要： | 小区大豆播种机田间作业时不同品种大豆需要人工换种,为解决换种效率低的问题,研究设计一种新型的自动转盘式小区大豆播种机自动供种装置。整个供种装置采用转盘式的圆形种盘与种杯组合的方式,使用PLC控制工作过程,完成小区大豆播种机播种过程中的自动换种。该自动供种装置包括机械部分和电控部分,其中机械部分由种杯、种盘、底座、安装支架等组成。试验对种杯进行了理论分析及结构设计,对电控部分进行了硬件选型及参数确定,并设计直流步进电机的控制软件。通过该自动供种装置进行室内台架试验,结果表明:种杯的偏移量合格率最大为99.6%,种子无破碎供种合格率最大为99.836%,具有较好的准确性和可靠性,符合小区播种机上种的农艺要求。

| Abstract: | In order to solve the problem of manual seed replacement in seeding different types soybean seeds in modern plot breeding, improving the seeding efficiency, a new automatic turntable soybean seed supplying device in plot seeders was designed. The whole construction of the device was composed of the round seed plate and some seed cups. All the seed supplying process was realized through a motor controlled by PLC. The electrical automatic seed supplying device was composed of the mechanical section and the electronic control section. The mechanical section was composed of seed cups, seed plate, pedestal and so on. The electronic control section was determined by hardware selection and parameter calculation. In this paper, theoretical analysis and structural design of seed cups were completed, DC stepping motor control was realized by the software design. The results of the platform experiment showed that, the maximum of the seed cup offset qualified rate was 99.6%, the maximum of the perfect seed rate was 99.836%. It had great accuracy and reliability and can meet the agricultural requirement of the plot seeders. |
