| 摘 要： | 传统铺膜播种机在地膜上打孔播种容易形成板结，不利于发芽破土能力弱的作物生长。该文针对这一问题，分析了膜下播种机设计的要求，对主要工作部件排种装置的结构进行了分析并给出了结构参数，采用参数化造型软件Pro_E设计该膜下播种机。参照铺膜播种机试验方法，对玉米播种就机器前进速度和取种器个数进行了单因素试验。试验结果表明：当排种筒转速高于72 r/min时，空穴率明显增加；根据相关参数，推出排种筒的最佳转速为57 r/min；对于播种大株距作物，作业速度可加快；播种小株距作物，作业速度应放慢。

| Abstract: | The traditional filming planter perforates on plastic film, which easily forms harden surface soil layer, it is not good for the growth of crops which have weak break ground ability. Aim at solving this question, the design requirements of the seeder under membrane were analyzed, and the primary structures of the planter were analyzed and a series of structural parameters of the key components were given. Seeder under membrane was designed by parametric modeling software Pro_E. Reference to the relevant national standard, the single factor experiments of the machine onward speed and the number of taking seed device were performed for the corn. Experimental results indicated that when the planter box rotate speed was higher than 72 r/min, the cavity void rate obviously increased. In accordance with the relevant parameters, the optimal planter box rotate speed was 57 r/min. For sowing large plant spacing crops, the speed of operation could be quickened, and for sowing small plant spacing crops, the speed of operation should be slowed down. |
