Abstract

The invention discloses an eccentric gear-noncircular gear planetary gear train vegetable pot seedling automatic transplanting mechanism. Gear boxes with the same structure are fixed at the two side shaft ends of a central shaft in a sprocket box extending out of the sprocket box. The two ends of a central shaft in the gear boxes are provided with central incompletely circular gears which are fixed on the sprocket box through a flange and fixedly connected with a convex locking arc; the central shaft and the gear boxes are fixedly connected and rotate together; intermediate shafts on the two sides of the central incompletely circular gears in the gear boxes are respectively symmetrically provided with an intermediate circular gear engaged with the central incompletely circular gears; the intermediate circular gears are respectively fixedly connected with a concave locking arc matched with the convex locking arc; the intermediate circular gears are respectively fixedly connected with an intermediate elliptic gear through the intermediate shaft; the intermediate elliptic gear is engaged with a planet elliptic gear fixedly fixed on a planet wheel shaft; and a transplanting arm is fixed at one end of the planet wheel shaft extending out of the gear boxes. Transplantation is carried out twice when the gear box rotates a circle, so that the working efficiency is improved; and the mechanism has the advantages of simple structure, small volume, light weight and small vibration.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an eccentric gear-non-circular gear planetary gear system automatic transplanting mechanism for vegetable pot seedlings. Background technique [0002] At present, domestic and foreign vegetable transplanting machines are mainly semi-automatic. Semi-automatic vegetable transplanting machines rely on manual feeding of seedlings, and the work efficiency is not high. The automatic vegetable 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 transplanting machine is relatively complicated, in today's ever-changing science and technology, the automatic vegetable transplanting machine will definitely be the main trend in the development of transplanting machines in the future. Contents of the invention [0003] The purpose of the present invention is to provide a...
