摘要: 根据小麦精播高产栽培农艺要求,研制了滚筒式小麦单粒精密排种器。介绍了排种器的结构和工作原理,给出了排种器台架试验结果。单粒排种频率可达45粒·s-1,合格指数在75.86以上,种子破损率小于0.49%,一个滚筒式排种器可以同时播2~6行小麦。Abstract: A new type of cylinder precision feeder for wheat was reported in this paper. The structure and working principle of the feeder were described. One set of the feeder can sow 2~6 rows,the feeding rate of single seed is 45 seeds per second,the correct rate is over 75.86 % and the split rate is less 0.49 %. The experimental results indicate that the sowing performance of the feeder is advanced comparing with other existing precision feeders for wheat.
