Abstract: In view of the opener of winter wheat no-till seeders was easy to be wrapped by grass,and difficult go into soil, and be jammed in the cold area, the duck mouth type opener was designed.The relation of different penetration angle, penetration clearance angle and three direction forces was measured by the field experiment. The effect of stability of seeding depth, forward resistance and penetration angle, penetration clearance angle was analyzed. The results showed the penetration angle and penetration clearance angle had significant effect on forward resistance and no significant effect on lateral and vertical force. Influence of penetration angle on the stability of seeding depth should be less than that of penetration clearance angle. Then, influence of penetrating angle on the forward resistance was more than the penetration clearance angle. The minimum values of forward resistance were observed when penetration angle was 30° and penetration clearance angle was 6°. It had a good ability to induce jam as good structure of opener.
