Design About the Pressure Hole Device Cleaning Mechanism of the Precision Seeder Based on TRIZ Theory

摘要

TRIZ theory is a powerful technology innovation theory, method and tool. It breaks through the mindset and can train innovative thinking, cultivate innovation ability, solve technological conflict, implement product innovation, and accurately predict the direction of new product development. In this paper, the TRIZ theory will be used to research on the pressure hole device cleaning mechanism of the precision seeder. The pressure hole device of seeder first in each point tray filled material by indentation is arranged in the indentation on the roller screw press a pit, the seeds are then sown accurately in each pit to complete the sowing operation. Because the matrix is damp, pressing pressure when used in nail plate, there is often a matrix residue in the indentation on the drum, if not timely cleaning, pressure point matrix on the roller will be more thick, resulting in matrix compaction and pressing nail cannot be inserted into the desired depth, effects of sowing and seedling. According to the defects of the existing technology and actual production, using the TRIZ theory to develop a real-time cleaning adhesion in the indentation on the roller matrix, prevent the tray matrix plate junction, and avoid pressing nail insertion depth is not enough, and has the advantages of simple structure, reliable operation of tray hole pressure drum seeder cleaning device.
