Abstract

The invention discloses a rice seedling transplanting mechanism with an eccentric circle and non-circular gear planetary gear train. Two ends of a central shaft are fixed with gear boxes with a same structure, and each gear box is provided with a transmission system which is composed of a lower planetary non-circular gear, a lower middle eccentric circle gear, a central incomplete non-circular gear, an upper middle elliptic gear, an upper planetary elliptic gear and two sets of backlash eliminating means. Transplanting arms are mounted at upper and lower planetary shafts. The gear boxes are used as input members, the central incomplete non-circular gears and the eccentric circle gears are engaged into a non-uniform intermittent motion, the eccentric circle gears and the planetary non-circular gears are engaged into a non-uniform transmission, and the combination of the two transmissions enables the transplanting arms to meet the requirements of transplanting track of rice seedling transplanting, with the gear boxes rotating for one circle and the transplanting arms transplanting the seedling for two times. Structural parameters are optimized, so that movement tracks of spring leaf tips on the transplanting arms can meet requirements of operating angles and movement tracks of the rice seedling transplanting mechanism, and automatic transplanting of the rice seedling transplanting mechanism can be ensured to be carried out reliably.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an eccentric circle-non-circular gear planetary gear train rice pot seedling transplanting mechanism. Background technique [0002] At present, compared with the rice transplanter, the rice pot seedling transplanter can increase production and income. Compared with the rice seedling throwing machine, the pot seedling transplanter has better uprightness and improves the rice output. However, the rice pot seedling transplanting machine introduced from Japan is expensive and not suitable for China's national conditions; the domestic rice pot seedling transplanting machine has low efficiency. Therefore, in order to realize the development and application of rice pot seedling planting technology in China and meet the needs of farmers for the mechanization of rice pot seedling planting, it is of great scientific significance and economic value to develop a new type of high-speed rice pot seedl...
