Double-planet carrier planetary gear train pot seedling transplanting mechanism

Abstract

The invention discloses a double-planet carrier planetary gear train pot seedling transplanting mechanism. According to an existing seedling taking and planting integrated pot seedling transplanting mechanism, seedlings can be taken through direct clamping only, and seedling roots can be damaged; if seedling taking and planting are realized through two sets of mechanisms, the whole mechanism can be quite complicated. According to the double-planet carrier planetary gear train pot seedling transplanting mechanism, a drive sprocket shaft and a center shaft are arranged at the two ends of a power driving box and supported by bearings, a drive sprocket fixedly connected to the drive sprocket shaft is connected with a center sprocket fixedly connected to the center shaft through a chain, two main planetary gear trains are symmetrically arranged at the two ends of the center shaft, and an upper auxiliary planetary gear train and a lower auxiliary planetary gear train are arranged at the two ends of each main planetary gear train respectively; an upper planting arm is fixed to each upper auxiliary planetary gear train, and a lower planting arm is fixed to each lower auxiliary planetary gear train. By the adoption of the double-planet carrier planetary gear train pot seedling transplanting mechanism, seedlings are taken by taking soil from a pot with one set of mechanism, and a seedling claw makes translational motion during seedling taking, so that the integrity of soil in the pot can be maintained; the distance between a seedling pushing section track and a gyration center of the mechanism is large, so that the working height of the whole mechanism is increased, 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 of a double-planetary planetary gear system 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 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 the mechanism, causing the wh...

[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
