目前烤烟育苗多为手工播种,费工费时,为了有效降低用工成本,提高劳动效率,满足新形势下烤烟漂浮育苗集约化、规模化、机械化的需要,设计了一种负压吸附式烤烟播种器。该机利用空气负压原理,通过精确打孔的播种盘吸附和释放烤烟种子,实现精准快速播种。据此理念结合实际应用,提出设计方案并试制了样机。通过检验,该机操作简便,播种精度好,播种效率高,较对照节省播种时间45.9%~83.9%,出苗率在92%以上,作业质量符合烟草播种育苗要求。
At present, most of flue-cured tobacco seedlings are hand-sown, time-consuming and labor-intensive. In order to reduce the labor cost effectively, improve the labor efficiency and meet the needs of intensive, large-scale and mechanized flue-cured tobacco seedlings under the new situation, . The machine uses the principle of negative air pressure, through precise perforated sowing tray adsorption and release of flue-cured tobacco seeds, to achieve precise and rapid sowing. According to the concept of practical application, put forward the design and prototype trial prototype. Through testing, the machine is easy to operate, sowing accuracy, sowing efficiency is high, compared with the control of sowing time 45.9% ~ 83.9%, the emergence rate of 92% or more, the quality of operations in line with tobacco sowing requirements.
