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

Abstract

The invention discloses a double planet carrier type non-circular and elliptical 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; the operation of taking the seedling and transplanting the seedling through two sets of mechanisms 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 environment of the mechanism is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a seedling transplanting mechanism with a double planet frame type non-circular-elliptical gear planetary gear system suitable for a seedling transplanting machine with high speed and large row spacing. 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 them, the clip seedling type is easy to cause damage to the stems at the bottom of the seedlings, and is not suitable for transplanting crops with relatively fragile seedling stems; while the clip-bowl type can reduce the damage to the seedling claws, but the distance between the seedling claws and the pot pan Larger ones make the track of the seedling pushing section closer to the center of rotation of th...

[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 them, the seedling clipping type is easy to cause damage to the stems at the bottom of the seedlings, and 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 distance that the seedling claws extend into the pot Larger ones make the trajectory of the seedling pushing section closer to the center of rotation of the mechanism, causing the whole mechanism to be too close to the ground, which is not conducive to seedling throwing; The pot is inserted into the soil to take the seedlings, and another set of mechanism realizes the planting, the whole mechanism is more complicated
