4YQ全幅玉米互换割台技术,是科技部“十一五”国家科技支撑计划重点项目“玉米收获机械化技术研究与示范”的子课题之一。4YQ-A(B)割台主要结合黄淮海一年两熟区和东北高产垄作区玉米成熟期的不同性能特点而研制,与谷物联合收获机互换割台,能适应多种行距玉米收获,解决了谷物联合收获机使用季节性强、利用率低这一弊端。试验结果表明,各项性能指标符合农艺和设计要求。
4YQ corn swap header technology, is the Ministry of Science and Technology “Eleventh Five-Year ” national key scientific and technological support program “corn harvesting mechanization technology research and demonstration ” one of the sub-topics. The 4YQ-A (B) header is mainly developed in accordance with the different performance characteristics of the corn ripening stage of the Huang-Huai-Hai one-year paddy field and the northeast high yield ridge-furrowing area, and the interchangeable header with the grain combine harvester, Solve the cereal combine harvester seasonal use, low utilization rate of this drawback. Test results show that the performance indicators in line with agronomic and design requirements.
