针对目前播种机的排种器普遍存在专机专用,不能满足播种多种作物的需要和难以实现精播、半精播、常量播种通用以及不能调节株距、难以结合实际确定种植密度等问题,笔者研制了一种组合式作物通用排种器。该排种器将原固定的外轮槽(窝)式排种轮改为排种槽(孔)大小可调的组合式排种轮,以满足播种多种作物需要;采用挡种板控制播种量,实现了作物精播、半精播及常量播种通用;加设了二级变速装置,可根据种植需要随意调整作物株距。其组装简单,使用方便,效果理想。
For the current seeder seeding machine widespread special plane, can not meet the needs of sowing a variety of crops and difficult to achieve precision sowing, semi-sowing, constant sowing common and can not adjust the spacing, it is difficult to determine the actual planting density and other issues, the author developed A combined crop universal seed metering device. The planter replaces the fixed outer wheel socket (nest) type seed wheel with a combined type seed wheel with adjustable size of the seed row slot (hole) to meet the needs of sowing a variety of crops; the seed board is used to control the sowing amount , To achieve the crop sowing, semi-sowing and constant sowing common; add a two-speed transmission device, according to the planting needs of crop spacing at random. The assembly is simple, easy to use, the effect is ideal.
