Abstract

The invention discloses a coaxial double rod ejection type elliptical-incomplete non-circular and circular gear planetary system seedling slinging mechanism. The mechanism comprises a planet carrier, wherein a central incomplete non-circular gear, a central incomplete circular gear, a first middle elliptical gear, a first middle incomplete circular gear, a second middle elliptical gear, a second middle incomplete circular gear, a first planet elliptical gear, a second planet elliptical gear and two seedling slinging transplanting arms are supported on the planet carrier; each of the seedling slinging transplanting arms comprises a transplanting arm housing, a hollow loop bar is slidably arranged in the transplanting arm housing, and a solid push rod is slidably arranged in the hollow loop bar; a first limiting plate, a second limiting plate and an opening and closing mechanism are arranged on the hollow loop bar; and a double outline cam, a shifting fork and a trigger are hinged in the transplanting arm housing. By adopting a layout plan of the two transplanting arms, planet carrier rotates once to fetch the seedlings and eject twice, so that the work efficiency is high; and the mechanism can be suitable for seedling slinging operations of a seedling slinging machine in a paddy field and a dry land at any rotating speeds.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a coaxial double-rod ejection type elliptical-incomplete non-circular and circular gear planetary system seedling throwing mechanism. Background technique [0002] At present, there are three main methods of rice mechanical planting: direct seeding, transplanting and throwing. Among them, direct seeding is a disorderly planting method with a long growth period. Transplanting has a slow seedling period of 5 to 7 days. Both methods will prolong the growth period; however, there is no slow seedling period for throwing seedlings. -15% yield. In addition, seedling throwing has the advantages of fast transplanting speed and no damage to the roots, and is recommended by rice planting experts as the planting technique with the highest yield increase rate. However, disorderly seedling throwing operation is not conducive to later field management, and affects rice ventil...
