摘要
在大量试验的基础上设计了集挖茬、拾茬、清茬、引茬、集茬和侧位条铺于一体的玉米根茬收获机。整机主要由根茬挖掘装置、清理捡拾装置、链式输送装置及悬挂和液压系统等组成。适用于玉米、高梁等作物根茬的挖掘和集铺。该机具采用偏置柄式挖掘铲和弹性伸缩式捡拾机构,实现了对非藕联玉米根茬的地表下捡拾。田间试验结果表明:根茬漏拔率小于2.8%,生产率0.955～1.086 hm2/h,作业幅宽2.6 m,整机可靠性系数96.8%。
A type of maize root stubble harvester based on a lot of test was designed. It can complete a serial of task including digging, picking, clearing, guiding, collecting and windrowing along side position in sequence. This harvester was consisted of the digging root stubble device, the clearing and picking device, the chain type transporting device, the suspension and hydraulic system, which was used for digging and collecting corn root stubble such as maize and sorghum. In this harvester, the digging shovel with offset handle and the flexible picking device with flex tooth were developed by self-innovation, which could finish picking process under surface for the root stubble of non-coupling maize. The field test results showed that the rate of non-picking root stubble was less than 2.8% , the productivity was 0. 955 - 1. 086 hm2/h, the operation broad width was 2.6 m and the reliability coefficient of the whole machine was 96.8%.
