一种新型的手推式多功能种子穴播机设计与试验

Design and Experiment of A New Kind of Push-type Multifunctional Seed Sowing Machine

为适应我国西北地区农民对农作物播种多样性的需求,解决传统穴播机播种功能单一、机器在换种时操作繁琐且种子清除不彻底的问题,设计了一种手推式多功能种子穴播机。采用储种室与播种轮分离的模式,解决了现有机器在换种时原有种子不易取出和彻底清除的问题。田间验证试验表明:新型手推式多功能种子穴播机在整地后播种,其空穴率、穴粒数合格率、播种深度均合格,满足农作物种植的农艺技术要求,换种时操作简便的需求,提高了播种机的实用性。

In order to meet the demand of farmers for sowing different kinds of seeds in northwest China,and to solve the problemsthat traditional hill planter has single sowing function,the operation is tedious and the seeds cannot be removed thoroughly whenchanging another kind of seeds,we design a hand-push and multifunctional hill planter.The machine adopted the model ofseparating the sowing wheel and seed-saving room.Field validation test showed that when the new hill planter was used for sowing,the rate of empty seed,rate of seeds per hole and depth of seeding were all qualified,so the hill planter can satisfy the requirementof agronomic techniques of crop planting,and the operation is easy when changing seeds,with high practicability.
