摘要
传统移栽机的分苗装置多数为旋转托杯式,动力消耗大、成本高,且在使用时容易出现挂苗现象。为此,在旋转托杯式分苗装置的基础上,对高精度全自动移栽装置进行设计与优化,旨在更好地实现瞬态分苗与接苗,提升作业效率,降低挂苗率。试验结果表明:当分苗装置的移动脉冲频率为25kHz时,直线运动的实际误差为0.2~0.8mm,符合作业要求;当自动分苗装置的分苗频率为45株/(行·min),分苗株数为90株/min,移动速度为199~397mm/s,分苗成功率为99.68%;当自动分苗装置的分苗频率为65株/(行·min)时,分苗株数为130株/min,机具的实际移动速度为363~726mm/s,未成功接收到的秧苗株数为3株,未成功落入栽植器中的秧苗株数为2株,分苗成功率为96.16%;当自动分苗装置的分苗频率为70株/(行·min),分苗株数为140株/min,移动速度为410~819mm/s,分苗成功率为95.04%。
Most of the seedling-dividing devices of traditional transplanters are rotary cup-type,which have large power system,high cost and easy to hang seedlings in use.Therefore,this paper will study on the basis of rotating cup seedling-separating device,through the design and optimization of high-precision automatic transplanting device,can better achieve transient seedling-separating and seedling-grafting,improve operational efficiency and reduce seedling-hanging rate.The specific test results are as follows:when the moving pulse frequency of the seedling-seeding device is 25000 Hz,the actual error of the device is 0.2-0.8mm in linear motion,which can meet the requirements of operation;when the seedling-seedling frequency of the automatic seedling-seeding device is 45 plants/min/row,the number of seedlings is 90 plants/min,and the actual moving speed of the machine is 199-397mm/s,and the success rate of seedling division is 99.68%.When the frequency of seedling division of the automatic seedling division device is 65 plants/min/row,the number of seedlings division is 130 plants/min,the actual moving speed of the machine is 363-726mm/s,and the unsuccessful received seedlings.The success rate of seedling division was 96.16%.When the frequency of seedling division of the automatic seedling division device was 70 plants/min/row,the number of seedlings was 140 plants/min,the actual moving speed of the device was 410-819mm/s,and the success rate of seedling division was 95.04%.
