The drive sprocket (404) of seed plate in the described seeding unit hopper, the drive sprocket of described fertilising axle head (703), by the intermediate chain wheel that is contained in frame (1) (104) and (104 ') transmission, this intermediate chain wheel (104), (104 ') are driven by the sprocket wheel that is connected in terminal pad (3) (301) that is contained in the plug-in type clutch (103) respectively.

Between the sprocket wheel (301) and intermediate chain wheel (104) of described terminal pad (3), between described intermediate chain wheel (104) and the seeding unit drive sprocket (404), between described intermediate chain wheel (104 ') and the fertilization axle sprocket wheel (703), stretcher (105), (106), (107) are housed respectively.

The utility model has following actively useful effect:

1, the reasonable combination of seeding unit and fertilizer applicator, plough and the wheel that jolt-squeezes is drawn with small tractor, can sow, applies fertilizer, jolt-squeeze, and the operating efficiency height is saved the labour.

2, adopt the transmission system of sprocket wheel chain, by being installed in the jackshaft transmission on the girder, and adopted the dicycly automatic chain tensioner respectively, guaranteed the reliability of seeding, fertilizer job run.

3, simple in structure, be convenient to promote.
