Pot seedling wide and narrow row spacing transplanting mechanism adopting seven non-standardize cone bevel gear planetary gear train

Abstract

The invention discloses a pot seedling wide and narrow row spacing transplanting mechanism adopting a seven non-standardize cone bevel gear planetary gear train. Identical gear boxes are fixed onto two ends of the central shaft of a transmission box; the central axis is sleeved with a central non-conic bevel gear of each gear box; each gear box is fixedly connected with the transmission box through a castellated flange; each central non-conic bevel gear is meshed with a first central non-conic bevel gear fixedly mounted on the central shaft, and drives a second central non-conic bevel gear coaxially mounted with the first central non-conic bevel gear to rotate; the second central non-conic bevel gear is meshed with a planetary non-conic bevel gear fixedly mounted on a planetary shaft; the shaft angle between the central shafts and the shaft angle between the planetary shaft and the central shaft are both sharp angles; after a seedling is taken by a seedling taking claw on a transplanting arm, the seedling pushing point deflects from the seedling taking point leftwards or rightwards for a certain distance to realize pot seedling wide and narrow row spacing transplanting. The overall gear ratio curve of a secondary gear mesh has two peaks which facilitate the forming of an '8'-shaped or sharp-angle-shaped spatial motion track for the seedling taking claw.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a seven non-conical bevel gear planetary gear train transplanting mechanism for wide and narrow row seedlings suitable for high-speed pot seedling wide and narrow row transplanting machine. Background technique [0002] Rice pot seedling transplanting is the process of transplanting the cultivated seedlings with nutrient soil pots into the field. Transplanting rice pot seedlings does not hurt seedlings and tillers early. Transplanting pot seedlings to the surface of the field with higher soil temperature can till tillering 5 to 7 days earlier than ordinary flat plate transplanting. Effective tillering at low nodes increases by 20%, saving 30 plants %, 80% water saving, 40% fertilizer saving, and an average yield increase of more than 5%, which is currently recognized as the best way to increase yield except for variety improvement. [0003] Wide and narrow row planting means that the ro...
