四功能回转杆地膜小麦穴播器运动分析和参数设计

Motion analysis and parameters design of direct insert model rotary level bunch－ planting unit

本文对直插式回转杆穴播器进行了运动分析，确定了穴播器的最优结构参数，穴播器的性能试验表明，该穴播器结构新颖，性能良好，克服了现有穴播器播种浅、撕膜严重、鸭嘴堵土、空穴率高等问题，是一种有广阔发展前景穴播部件。

Motion analysis and parameters design on direct insert model rotary guide bunch－ planting unit have made to determine its parameters and optimal structure. The performance tests of bunch－ planting drop unit have showed that performance of bunch planting unit presented is satisfactory, and its structure creative, present many problems are solved such as upper seeding、 seriously dilacerate mulch film、 duckbill mounted soil blocking up、 high empty hole rate problem. The unit is a kind of update bunch－ planting working part。
