Double planet carrier type circular gear and non-circular gear planetary gear set pot seedling transplanting mechanism

Abstract

The invention discloses a double planet carrier type circular gear and non-circular gear planetary gear set pot seedling transplanting mechanism. An existing seedling taking and transplanting integrated pot seedling transplanting mechanism takes a seedling only by directly clamping the seedling, thus damaging a root of the seeding; if taking the seedling and transplanting the seedling through two sets of mechanisms, the whole mechanism is relatively complex. A drive sprocket shaft and a central shaft are supported at the two ends of a power drive box through bearings, a drive sprocket fixedly connected on the drive sprocket shaft is connected with a central sprocket fixedly connected on the central shaft through a chain, two main planetary gear sets are arranged symmetrically at the two ends of the central shaft, an upper auxiliary planetary gear set and a lower planetary gear set are respectively arranged at the two ends of the main planetary gear set, the upper auxiliary planetary gear set is provided with an upper transplanting arm, and the lower auxiliary planetary gear set is provided with a lower transplanting arm. The seedling is taken with soil from a pot through one set of the mechanism, a seedling claw is in translation motion in the stage of taking the seedling, the integrity of the pot soil is kept, the distance from the track of a seedling pushing section to the rotation center of the mechanism is relatively far, and the working height of the whole mechanism is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a circular gear-non-circular gear double planetary gear system pot seedling transplanting mechanism suitable for a high-speed, large-row-spacing, and integrated pot seedling transplanting machine. Background technique [0002] At present, most pot seedling transplanting mechanisms are divided into two categories: one is to use a set of single-planet carrier two-stage gear transmission mechanism to achieve seedling picking and planting. The pot type, among which the seedling clipping type is easy to cause damage to the stems at the bottom of the seedlings, is not suitable for transplanting crops with relatively fragile stems; while the clipping pot type can reduce the damage to the seedling claws, but the seedling claws extend into the pot. The trajectory of the ambassador’s seedling pushing section is relatively close to the center of rotation of the mechanism, w...

[0002] At present, most pot seedling transplanting mechanisms are divided into two categories: one is to use a set of single planet carrier two-stage gear transmission mechanism to achieve seedling picking and planting. The pot type, among which the seedling clipping type is easy to cause damage to the stems at the bottom of the seedlings, is not suitable for transplanting crops with relatively fragile stems; while the clipping pot type can reduce the damage to the seedling claws, but the seedling claws extend into the pot. The trajectory of the ambassador’s seedling pushing section is relatively close to the center of rotation of the mechanism, which causes the entire mechanism to be too close to the ground, which is not conducive to seedling throwing; the other type is to divide the seedling taking and planting actions into two sets of mechanisms, and one set of mechanisms is used to achieve potting Take the seedlings with the soil, and another set of mechanism realizes the planting, the whole mechanism is more complicated
