Design and Control of Metering System and Furrow Openers for Garlic Planter

  • 摘要: 目前的大蒜播种机为8行式,本研究侧重于通过减少播种机的设计方案以增加播种能力,通过增加最佳行数和种子均匀度来增加田间作业效率。对于新设计的10行式大蒜播种机,来自农场的测试结果以下列标准为基础:工作速度1.68kmh,输种管高于地面30cm,且为最低变量。田间工作效率0.13hm2h,株距11.73cm,打滑率10.36%。开沟器为靴式,2行,行间距为250mm,拉力为10.3N行,且保持不变。大蒜平均发芽率为74.57%,平均单产26919kghm2,而农户的平均种植产量为30419kghm2。人力种植的精度值为20.93%,而10行大蒜播种机的精度值平均为21.0%。

     

    Abstract: Presently,the garlic planter is an 8-row type.This research has focused on increasing the planter capacity by reducing the draft of the planter,increasing the field efficiency by increasing the optimum number of rows and increasing the uniformity of the seed.For the 10-row garlic planter,the test results obtained from the farmer′s field were based on the following criteria:working speed 1.68kmh,height of the seed delivery tube above ground level 30cm,which was the lowest variation.The field capacity was 0.13hm2h and plant spacing was 11.73cm.The percentage of slip was 10.36%.The furrow opener is a shoe type,placed in two lines with spacing of 250mm between the lines.It gave a constant draft force of about 10.3Nrow.The percentage of germination was 74.57%.The average yield was 26919 kghm2,whilst the average yield of planting by the farmer was 30419 kghm2.The precision value for human planting was 20.93% while the 10-row garlic planter was 21.0%,on average.
