| 摘 要： | 以拆除插植装置后的高地隙乘坐式插秧机底盘为动力底盘,在其上增设割台、输送槽、集穗箱以及第二动力等装置,设计一种专用于再生稻穗头收获的高地隙割穗机。对该高地隙割穗机的割幅、生产率、行走功率等主要工作参数进行理论计算,对其螺旋推运器、割台、输送装置等主要工作部件的结构及运动参数进行分析,并试制割幅为1.6m、理论喂入量为1.8kg/s的样机。以"两优28"、"黄华占"水稻品种为试验对象,在试验田对该割穗机进行收获及稻茬碾压性能田间试验。结果表明:该机田间碾压率≤25.15%,割茬高度在250~650mm间无级调节,纯工作效率约为0.24hm2/h,满足再生稻穗头收获作业要求。

Designing and performance testing a novel head spike harvester of ratoon rice |
| |
| Abstract: | A prototype of head spike harvester was designed based on a transplanter with high ground clearance and without transplanting device.The harvester was used to harvest ratoon rice in field. The harvester contained helix transport,cutting platform,conveyor trough,grain tank and the second power.The parameters of structure and motion were calculated based on the agronomic requirements of ratoon rice in China.Its cutting width is 1.6 m and feeding amount is 1.8 kg/s.The three dimensional model of the harvester was designed by Pro/E.The performance test of the prototype harvester was con-ducted in the experiment farm on Huazhong Agricultural University campus.Rice varieties were “Lian-gyou28”and “Huanghuazhan”.The soil firmness was 1 081.21 kPa and 1 898.55 kPa,respectively.The soil moisture content was 25.56% and 1 9.71%,respectively.The results showed that the mass distribu-tion and equilibrium ability of prototype harvester was well.The rate of stubble pushing was less than 25.15%.The stubble height can be adjusted from 250 mm to 650 mm.The pure field work efficiency was more than 0.24 hm2/h meeting the practicial requirements. |
