陕西省林业机械研究所研制的4QDL型大苗联合起苗机,主要用于平作苗圃起大苗作业,经一次作业能完成掘苗、抖土、苗木收集、归堆等工序。该机具有一定的新颖性,参数选择与结构设备比较合理,能较好地克服因苗铲侧置而产生的偏牵引现象,机组直线行驶性能好;起苗机掘土切根均很顺利,在一般沙壤土苗地碎土效果更好;采用波状输
Shaanxi Provincial Forestry Machinery Research Institute developed 4QDL large seedling seedling raising machine, mainly for flat seedlings nursery operations, through a homework to complete digging seedlings, shaking soil, seedlings collected, the pile and other processes. The machine has a certain novelty, the parameter selection and the structural equipment are more reasonable, which can better overcome the partial pulling phenomenon caused by the seedling shoveling, and the straight running performance of the unit is good; the seedling machine digging soil cutting roots are all very smooth, In general sandy loam soil Miao soil better; using wavy transport
