2BM-5型气吸式免耕播种机田间播种性能试验
Field Sowing Performance Test of 2BM-5 Type of Air Suction and no Tillage Planter
摘要
Abstract
In order to improve seeding accuracy of the 2BM-5 type of air suction and no tillage planter, after optimization of the key parts of the machine are improved, field seeding performance test was carried out.The experimental results show that the measured sowing machine driving wheel slip rate is 5.7%,the sinking depth of The wheels is 17mm, when the speed is 3~5 km/h, the sowing depth kept between 30~70mm in width,when forward speed is 3~5km/h, the ground breaking width is between 50~100mm, the particle distance qualified index is 86.01%, the repeat sowing index is 7.74%,the leakage sowing index is 6.33%,the average of qualified grain distance variation coefficient is 4.86%,the average of consistency variation coefficient of fertilizer quantity in each row is 3.44%, the Stability coefficient of variation of the total quantity of the fertilizer discharging is 0.26%,the average of sowing depth qualified rate is 89.81%, the average of fertilizer depth qualified rate is 88.23%, all indexes are in line with no tillage sowing technology index.关键词
