大蒜两级取种装置的设计与试验优化

针对勺链式取种方式在蒜箱与取种勺接触部分容易出现空穴而导致漏取的问题,采用两级取种的设计思路,优化了取蒜勺的取种环境,并通过对两级取种装置的结构设计与理论研究,确定了两级取种装置的结构参数.以取种勺的勺宽、弧度半径和挡板高度为试验因素,以漏播指数、重播指数、合格指数为试验指标,进行多因素取种试验,得到试验因素对影响两级...

Design and Test Optimization of Garlic Two-stage Seeding Device

For the spoon chain way in the garlic box and seed spoon contact part easy to appear holes lead to leakage of the problem of research, the use of two-stage seed design ideas, optimize the seeding environment, through the two-stage seeding device structure design and theoretical research, determine the two-stage seeding device structure parameters. In the process of seeding, the spoon width, radii radius and bezel height of the seed are taken as the test factors, the leakage index, the replay index, the qualifying index are the test indicators, the multi-factor sampling test is carried out, and the test factoris is arranged for the main sub-factors affecting the performance of the two-stage seeding device as: spoon width、radii radius、bezel height. Using the Design-Expert software parameter optimization function, the optimization function is optimized to obtain the optimal parameter combination range with low leakage index, low replay index and high qualifying index as the constraint: when the spoon width is 24.2 mm, the arc radius is 18.8 mm, the bezel height is 12 mm, the theoretical leakage index is 1.90%, the replay index is 2.36% and the qualifying index is 95.74%. Through field tests, the leakage index of field tests was 1.8%,the replay index was 2.6%,and the qualifying index was 95.6%, which was basically consistent with the theoretical results and better than the local standard requirements of garlic seeders in Shandong Province.
