The invention discloses an eccentric gear-incomplete non-circular gear planetary gear plug seedling picking mechanism. Power inside a sprocket box is transmitted to a center shaft, one end of which is fixed with a gear box. Longitudinally symmetrical planetary gear mechanisms are installed inside the gear box. An upper and lower planetary shaft that extend out of the gear box are respectively equipped with a seedling pickling arm of the same structure. An incomplete non-circular gear inside the gear box is fixed at one side of the sprocket box and is engaged with an upper and a lower eccentric gear respectively, and the upper and a lower eccentric gear are engaged with an upper and a lower planetary non-circular gear respectively. The incomplete non-circular gear is in coaxial and fixed connection with a convex locking arc, and the upper and the lower eccentric gear are coaxially in fixed connection with an upper and a lower concave locking arc respectively. In the invention, two sets of planetary gear transmission mechanisms are arranged relative to the center shaft, and set drives the motion of a seedling picking arm. Each circle of turning by the gear box can realize twice seedling picking. The plug seedling picking mechanism of the invention has the advantages of high operation efficiency, simple structure, small volume, light weight, and small vibration.
Description
technical field [0001] The invention relates to agricultural machinery, in particular to an eccentric circular gear-incomplete non-circular gear planetary gear system plug seedling picking mechanism of an automatic seedling picking machine for plug seedlings. Background technique [0002] At present, the plug seedling transplanting machines at home and abroad are mainly semi-automatic. The semi-automatic plug seedling transplanting machines rely on manual feeding of seedlings, and the work efficiency is not high. When the planting speed is high, the rate of missing seedlings and seedlings is greatly Increase. The automatic tray seedling transplanting machine has automatic feeding and picking of seedlings, which is more automated and labor-saving, and has high work efficiency. Although the structure of the automatic tray seedling transplanting machine is relatively complicated, in today's ever-changing science and technology, the automatic tray seedling transplanting machine...
