Conservation tillage northern dry farming sustainable development is an integrated agro-ecological engineering technology . The key to the application and promotion of conservation tillage technology is the no-till seeder . Currently, the core issue in the development of no-tillage planter at home and abroad till planter clear grass Paidu of problems . Agricultural experts at home and abroad in the no-tillage seeder achieved certain results , the applications Paidu and attempts to prevent the device different types , but they were not fundamentally solve this problem. It was from that point , the classification and analysis of tillage planter at home and abroad in the past attempts to prevent the device and how it works , and compares their advantages and disadvantages , combined till covering the straw biomechanical properties and the comparative analysis of the different cutting methods , conceived on the basis of the slip -cut grass- Paidu device 's basic principles and overall structure of the design . Design suitable for this device attempts to prevent the power transmission , power by the gearbox change to the variable speed pass from the right side of the knife shaft , driven blade cutting straw ; determine the parameters , the blade of the knife shaft mounting structure and installation method , by the force and motion of the tool axis were analyzed to determine the best speed of the tool axis ; depending on the requirements of the till , select the appropriate opener, and the double row dislocation installation way to avoid the occurrence of the phenomenon of the \attempts to prevent the key components of the device - a slide cutter blade edge curve theory analysis and design ; slip requirements of this blade theoretical curve equation ; production practice and process requirements , design the shape of the blade parameters, select the 65Mn as the material of the blade ; analysis and calculations bear the load of the blade at work , using ANSYS software slide cutter blade strength check ; spring support structure last round of repression carried out theoretical analysis presented the design theory and parameters based on suppression of the wheel spring support . The tests showed that good the Qing the grass Paidu performance of the attempts to prevent the device . Cut corn stubble and surface wheat or corn stalks , during tillage sowing of wheat basic clogging . Install this device attempts to prevent the planter compact , less power consumption , wide adaptability advantages.
