禾本科牧草种子采集装置设计与试验

Design and Experiment of Pick Device for Gramineous Grass Seed

针对谷物联合收割机全喂入收获方式不适用于牧草种子的收获,同时由于豆科牧草种子和禾本科牧草种子的物理特性不同,我国现有的自走式牧草种子专用收获装备主要适用于收获豆科牧草种子,对于禾本科牧草种子收获质量较差、损失率较高等问题,在9ZZ-2.4型自走式牧草种子收获机的基础上,研制了一种新型的可与豆科采集台互换的禾本科牧草种子采集装置,结构简单、操控方便,各项技术参数与原有收获机匹配良好,具有广泛转化和示范推广意义。

The full-feed harvesting method for grain combine harvester is not suitable for harvest of forage seeds.At the same time,due to different physical properties of legume forage seeds and gramineous forage seeds,existing self-propelled forage seed harvesting equipment in China is mainly used to harvest leguminous forage seeds.The harvest quality of gramineous forage seeds is average and loss rate is relatively high.Based on 9ZZ-2.4 self-propelled forage seed harvester,new type of gramineous forage seed harvesting device was discussed,which could be interchanged with legume collection platform.It had simple structure and convenient operation.Various technical parameters matched well with original harvester,and results were worthy of transformation and demonstration.
