|
摘要
气吸式免耕播种机除实现免耕以外,同时还要实现精密播种。因此本研究根据免耕播种机气吸式排种装置的结构特点,借助ANSYS软件对气吸式排种装置进行了气流场有限元分析及试验研究,其结论为免耕播种机气吸式排种装置的结构优化和性能的提高提供了参考。
本文主要研究了不同孔型、孔径和吸孔分布状况下气流场的分布规律和排种性能,找出了孔型结构为锥孔、吸孔孔径为5.0mm、吸种孔分布直径为150mm的吸种性能最佳。气吸式排种装置的气流场有限元分析显示:直孔、倒角孔、锥孔三种孔型入口气流速度变化不很明显;3.2mm、4.2mm、5.0mm三种孔径的吸种孔入口气流速度是孔径为5.0mm最大;130mm、140mm、150mm三种不同吸孔分布直径的真空室入口气流平均速度是150mm最大。激振与传统排种性能试验的结果为:改变吸种孔的孔型结构的试验结果显示锥孔的吸种性能最佳;改变吸种孔的孔径大小的试验结果显示孔径为5.0mm的吸种性能最佳;改变吸种孔的分布直径的试验结果显示分布直径为150mm的吸种性能最佳;同时从总体的排种性能试验结果可以得出激振试验优于传统试验。
Air-suction no-till planter achieves no-till planning, but also precision planting. Therefore, this study according to structural characteristics of air-suction seed metering device of no-tillage planter, using ANSYS software on air-suction seed metering device carried on airflow field finite element analysis and experimental research, the conclusion provide structure optimization and performance improvement reference of air-suction seed metering device of no-tillage planter.
This paper mainly studied flow field of the distribution and seeding performance under the Conditions of different pass, Aperture and pore distribution, Found out best suction performance which the hole structure was the tapered hole, suckers aperture was 5.0mm, and diameter of suction hole was 150mm. Airflow field finite element analysis of air-suction seed metering device display: straight hole, chamfer hole, tapered hole,three hole diversification of inlet flow velocity is not very obvious; 3.2mm, 4.2mm, 5.0mm, three aperture of suction hole which the largest inlet air flow speed is 5.0 mm hole; 130mm, 140mm, 150mm suction holes distributed in three different diameter which the maximum inlet air flow average speed of the vacuum chamber is 150mm. Excitation and traditional seeding performance test results are: test results of changing suction hole structure showed that tapered hole’s absorbing seed performance is best; the test results of changing pore size of the suction hole showed the 5.0mm aperture’s absorption performance is best ; the test results of changing the distribution diameter of absorbing hole showed absorbing seed performance of the 150mm distribution diameter is best; while from the overall results of seeding performance can be obtained vibration test superior to the traditional test.
