Design and experiment on furrowing and anti-blocking unit for no-till planter
摘要
Abstract
In order to solve the problems of residue blocking and difficulty to open the furrow of no-till wheat planter in heavy corn residue cover fields in annual double cropping areas of the North China, a telescopic lever furrowing and anti-blocking unit was designed for no-till planter. Its key parameters were determined based on a band between orthogonal test and the structure analysis, and a telescopic lever furrowing and anti-blocking unit was used to conduct the field experiment. The field experiment showed that the telescopic lever furrowing and anti-blocking unit could solve the problem of straw blocking effectively and improve the seeding quality. Compared with the strip rotary-tilling anti-blocking unit, the telescopic lever furrowing and anti-blocking unit could reduce topsoil disturbance quantity by 21.5%; fuel consumption per unit area was reduced by 23.65% when the depth of furrow opening was 10cm, which could reduce power consumption of tractor. Above all, the telescopic lever furrowing and anti-blocking unit has important value in extending no-tillage planter.关键词
