摆杆排种器是根据我国传统农具——耧的工作原理,研制成的一种排种器。它的结构紧凑、金属耗量小、能条播多种作物。例如小麦、高粱、谷子、油菜、豆类、白菜、萝卜、大葱、苜蓿、沙打旺等。它和外槽轮式排种器相比,在播种小麦、高粱、谷子和玉米时,其排种均匀性提高10～30％左右。尤其是在播种小粒种子时,不仅能把亩播量控制在一斤范围内,而且均匀性好、破碎率小,显示出其独特的优点。 本文根据大量试验数据,对摆杆排种器的运动学分析、工作原理、排种性能以及参数选择、结构设计进行了初步分析和探讨。
Pendulum seed metering device is based on the traditional Chinese farm tools - 工 working principle, developed a seed device. Its compact structure, metal consumption, can sow a variety of crops. For example, wheat, sorghum, millet, rape, beans, cabbage, radish, green onions, alfalfa, sand Astragalus and so on. Compared with the outer tank wheel seed metering device, when it is planted with wheat, sorghum, millet and corn, the uniformity of the seeds is improved by about 10 to 30%. Especially in the sowing of small seeds, not only can control the acres of sowing range, but also good uniformity, small broken rate, showing its unique advantages. In this paper, based on a large number of experimental data, the pendulum bar rammer kinematics analysis, working principle, seed performance and parameter selection, structural design were initially analyzed and discussed.
