Study on the Light No-till Seeders With High Anti-blockage Performance

Gao Huanwen,Li Hongwen,Yao Zonglu

Strategic Study of CAE 2007, Volume 9, Issue 9, Pages 35-39

Abstract:

The first performance of the no -till seeder is to avoid the stalk blockage while seeding. To solve the blockage problem, oversea no-till seeders mostly rely on heavy weight (760-1130 kg/m) or big size. But those seeders are not suitable for Chinese conditions of small land size, small tractor and weak left force (300~600 kg/m), and are expensive as well. After 10 year efforts since 1990, light passive anti-blockage no-till seeders were developed and largely applied to the middle and low yield regions. However, the anti-blockage performance of the seeders is limited, difficult to work in the high yield region. From 1998, 3 types of light and active anti-blockage no-till seeders, strip rotary hoe, strip chopping and power driven disk no- till seeders, have been developed. Those seeders have strong anti-blockage ability, and can directly seed wheat on the heavy maize stalk mulching field. The unit weight is 316~500 kg/m, which can matchdomestic tractors. The price is 1/8 of oversea no-till seeders. From the planting quality test of 3 no-till seeders in 2004~2006, the light active anti-blockage no-till seeders have shown more soil disturbance and power consuming than oversea no-till seeders, but had advantages of wheat emergence, seedling growth and wheat yield. Nearly 20, 000 pieces of the light & high anti- blockage no-till seeders have been applied to the direct seeding wheat in maize stalk mulching field of 400, 000 hm2 in 2006, resulted resources saving, environment protection and farmer benefits increasing.

Theory and method of mechanism system design

Huijun ZOU, Qinghua LIANG, Qing ZHANG

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4, Pages 399-411 doi: 10.1007/s11465-010-0116-8

Abstract: Conceptual design is the most critical and creative phase of design. Recently, increasing attention has been directed to supporting conceptual-level computer aided creative design and its theories and methodologies. Specifically, for conceptual design of mechanical products, this paper presents a novel function solving model for mechanical product design and highlights the importance of systematic synthesis to achieve creative design. Then it builds a framework as a function-effect-process-action- mechanisms (FEPAM) mapping process, which enables creative design on the basis of conceiving different action schemes. After that, several key points are elaborated including 1) representing and decomposition methods of functions and motion behaviors; 2) action scheme representing method based on network plan techniques; and 3) variation and creation methods based on action scheme transformations.
