The utility model relates to a no -tillage seeding machinery technical field among the agricultural machine. Its key feature lies in: the terminal flange of crank 10 that adopts crank mechanism 5 and the mode of installing lead kind of intubate 4 on ejector pin in the guide rail 9 and reset spring 8 combined effect, the opening and closing of realization dibbling duckbilled, vertically parallel four sets of these type dibblers in 3 each sides of frame, four sets of dibbler run -in synchronisms on the right side, run -in synchronism is carried out at the phase angle that the crank of four sets of dibblers on crank and the right side of four sets of dibblers in the left side differed certain. Compared with the prior art, the utility model discloses a dibbler simple structure, duckbilled open and close rapid accuracy, and the seeder volume of compriseing this dibbler of breaking ground is little, and the field trafficability characteristic can be good, is particularly suitable for no -tillage seeding.
