摘要
依据旋转锹的工作原理,设计了一种绿肥翻青机,确定了该机的主要结构,测试了其工作性能。翻青装置中侧刀的侧切刃采用正弦指数曲线,可有效防止机组在多草田耕作时侧刀缠草;顶板可辅助土垡翻转,刮土装置可将粘附在侧刀上的土块刮下,减少侧刀粘土。田间功能性试验表明,该机翻青覆盖率可达85%以上,耕深最大可达200 mm,且功耗低,能够满足设计要求,可实现绿肥、水稻、小麦等秸秆的机械化翻埋还田。
A green manure embedding machine was developed according to the operational principle of rotary spade. The main structure and working process of the machine were determined. The lengthwise edge of the blades can effectively prevent the blades from winding the grasses by using the sine index curve. A top plate was equipped to assist the furrow slice to turn over. A soil scraping device was equipped to scrape the soil adhering to the blade. The results of field tests showed as follows： the green manure coverage rate was more than 85%, the maximum tillage depth was 200 mm. The power consumption of the machine was lower. This machine meets the design requirements and returns green manure, rice straws and wheat straws to the field through mechanization operation. It would be important, practical and valuable to improve the utilization ratio of the existing straws.
