Double planetary frame circular gear - non-circular gear planetary gear system pot seedling transplanting mechanism

Abstract

The invention discloses a double-planet frame type circular gear-non-circular gear planetary gear system seedling transplanting mechanism. The existing pot seedling transplanting mechanism that integrates seedling taking and planting can only take seedlings by directly clamping the seedlings, which will damage the roots of the seedlings; taking seedlings and planting is realized by two sets of mechanisms, and the whole mechanism is relatively complicated. The driving sprocket shaft and the central shaft of the present invention are supported at both ends of the power drive box through bearings; the driving sprocket fixed on the driving sprocket shaft is connected with the central sprocket fixed on the central shaft through a chain; the two ends of the central shaft There are two main planetary gear trains symmetrically, and the upper minor planetary gear train and the lower minor planetary gear train are arranged at both ends of the main planetary gear train; the upper minor planetary gear train is fixed with an upper planting arm, and the lower minor planetary gear train is fixed Lower planting arm. The present invention uses a set of mechanism to realize the soil-into-the-bowl-type seedling extraction, and in the seedling-taking stage, the seedling claws are in translational motion, which can maintain the integrity of the pot soil, and the trajectory of the seedling pushing section is far away from the center of rotation of the mechanism, so that the work of the whole mechanism Height rises.

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
