Design and simulation of three rigid-one flexible forming hole mechanism of film mulch and punch planter
摘要
Abstract
Pointed at the problem of large disturbance and seriously tearing film when corn film mulch and punch planter perpendicularly inserted the soil by parallel four-bar mechanism in our country,designed out the three rigid-one flexible forming hole mechanism,the parallel four-bar mechanism was replaced by the spring damping pole.Based on the Adams,established the simulation models as three rigid-one flexible mechanism and parallel four-bar mechanism,and which was simulated at the same conditions.The results showed that:The forming hole pole of the three rigid-one flexible mechanism was less change of displacement and smooth in the level direction in x axis than the parallel four-bar mecha-nism,while in y axis,the vertical direction trend was basically consistent.The pole of the three rigid-one flexible form-ing hole mechanism had slight disturbance to the front and back soil model,but the parallel four-bar mechanism only dis-turbed to the front soil,the disturbing force was 9.4 times higher than the three rigid-one flexible mechanism.Therefore, the design of three rigid-one flexible mechanism had less soil disturbance,useful seed germination compared with parallel four-bar mechanism.The forming hole pole can be recovered to the state of perpendicularly inserting soil when the pole don’t impose force,which had less damage to the film mulch.关键词
