Embedded Double-position Throwing Seeds Dibbler

Abstract:

A dibbler with embedded doubleposition throwing seeds was presented. Variable seedmetering device on the position was layout in the center of helmshaped wheel for shortening the distance of dropping seeds and omitting gearing device. Boring and caving device was composed with fixed part and rotatable part, always closed in the state of non-opening. Based on the lever principle, rotatable part was opened when the most depth in the soil was reached. The second lower position throwing seeds was completed, and then rotatable part was came up out of soil and closed. The experiment results showed that the proposed dibbler could meet the design and agriculture requirements. 
