Dual-planet-carrier elliptical non-circular gear planetary gear train pot seedling transplanting mechanism

Abstract

The invention provides a dual-planet-carrier elliptical non-circular gear planetary gear train pot seedling transplanting mechanism. An existing pot seedling transplanting mechanism integrating seedling taking and transplanting capability can take seedlings only by virtue of a direct seedling clamping mode, and therefore, damage is caused to roots of the seedlings; seedling taking and transplanting are realized by virtue of two mechanisms, and therefore, the overall mechanism is relatively complicated. A drive sprocket shaft and a central shaft are supported on two ends of a power drive box by virtue of bearings; a drive sprocket fixed to the drive sprocket shaft is connected with a central sprocket fixedly connected to the central shaft by virtue of a chain; two ends of the central shaft are symmetrically provided with two main planetary gear trains; an upper auxiliary planetary gear train and the lower auxiliary planetary gear train are respectively arranged at two ends of the main planetary gear train. The upper auxiliary planetary gear train is provided with an upper transplanting arm, and the lower planetary gear train is provided with a lower transplanting arm. By use of one mechanism, seedlings are taken in a manner of extending into a pot and taking soil; in the seedling taking process, a seedling claw translates, so that the pot soil integrality can be kept to the greatest extent; and the locus of a seedling push segment is far away from the rotation center of the mechanism, so that the working height of the overall mechanism is increased.

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 ellipse-non-circular 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 the m...
