Abstract


This paper is under no-tillage sowing one crop areas of northern China to the actual needs of proposed study , its purpose is to meet the production needs of farmers , to further improve rainfed conservation tillage equipment system . In this paper, mainly small and the overall profiling study , which mainly small tractors and Rural adapt , and the structure is simple and low cost . From a content point of view , can be divided into six lines of the overall profiling wheat no-tillage planter design and experimental study and staggered double disc opener of exploration and study . Limit of six lines of the overall profiling of wheat no-tillage planter easy to hang from solving the wheat row spacing is narrow, no-tillage sowing grass research . The aircraft will be ditching the front-rear two rows of staggered , increasing the distance between adjacent opener , while the front and rear opener in straight two forms of Shanks , thereby increasing the straw above the shovel handle sliding off . Judging from the results of field trials , although the overall profiling , but compact , planter as a whole span of small , undulating table location of the machine , better quality planting encountered straw timely off to avoid clogging happen. The staggered double disc opener major largest corn stubble tillage sowing , easy to hang the crop caused by blockage, or pick out the stubble cause the casing issues such as inadequate study in order to solve the sharp corners opener . Before and after the opener by increasing the two - disc stagger distance , increasing the disc diameter parameter optimization , a disc cutting grass , split stubble , ditching , another disc to broaden the width of the trenching , to meet the kind of fat side of the Shi width requirements, improve the performance of disc opener buried . Judging from the results of field trials , the opener has a good anti-blocking performance , but requires a large positive pressure test machine weights of 350kg, the total weight of 570kg buried depth , stubble - breaking performance can well meet the requirements, the value of the further research and development .
