摘要
为提高水稻育苗覆土机构的实用性,根据丹东地区分散育苗的特点,设计了一种新型水稻苗床育苗覆土机构。该机构的工作原理是改固定拨齿为伸缩拨齿,在拨齿通过覆土辊栅条缝隙回缩的时候,将粘在拨齿的土壤刮掉,保证拨齿的容积空间不变,从而确保排土持续、均匀。
A new type of soil cover machine in raising rice seedlings was designed in view of the actuality of scattered rice seedling in Dandong so as to improve the performance of these tools.The key of the working principle of the invented machine lies in converting the set covering into flexible covering,which will scrape the soil off the dialing tooth so as to ensure an even and continued earth casting.
