Pot Seedling Transplanting Mechanism with Noncircular Gear Double Planetary Gear System

Abstract

The invention discloses a non-circular gear double planetary gear train pot seedling transplanting mechanism. An existing pot seedling transplanting mechanism which integrates seedling picking and planting can only be used for picking seedlings by using a direct seedling gripping mode and can cause damages to seedling roots; and if seedling picking and planting operations are implemented by virtue of two sets of mechanisms, the whole mechanism is relatively complex. According to the non-circular gear double planetary gear train pot seedling transplanting mechanism, a driving chain wheel shaft and a center shaft are supported at two ends of a power driving box by virtue of bearings; a driving chain wheel which is fixedly connected with the driving chain wheel shaft is connected with a central chain wheel which is fixedly connected with the center shaft by virtue of chains; two primary planetary gear trains are symmetrically arranged at two ends of the center shaft, and an upper secondary planetary gear train and a lower secondary planetary gear train are respectively arranged at two ends of each primary planetary gear train; and an upper planting arm is fixedly arranged on each upper secondary planetary gear train, and a lower planting arm is fixedly arranged on each lower secondary planetary gear train. According to the non-circular gear double planetary gear train pot seedling transplanting mechanism disclosed by the invention, an in-pot soil sampling type seedling picking mode can be achieved by using one set of mechanism; and moreover, seedling claws are in translational motion in a seedling picking stage, and thus the integrity of pot soil can be maintained to a greatest extent.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a non-circular gear double-planetary gear system pot seedling transplanting mechanism suitable for a high-speed, large row-spacing pot seedling transplanting machine. Background technique [0002] At present, most of the pot seedling transplanting mechanisms are divided into two categories: one is to use a set of mechanisms to achieve seedling taking and planting, but its disadvantage is that the trajectory during the seedling taking process cannot be deep into the pot, and the seedlings can only be directly clamped. The method of picking seedlings will cause certain damage to the roots of the seedlings, and the trajectory of the seedling pushing section is relatively close to the center of rotation of the mechanism, causing the entire mechanism to be too close to the ground, and the working environment of the mechanism is even worse; the other is to use two sets ...

The method of picking seedlings will cause certain damage to the roots of the seedlings, and the trajectory of the seedling pushing section is relatively close to the center of rotation of the mechanism, causing the entire mechanism to be too close to the ground, and the working environment of the mechanism is even worse; the other is to use two sets of mechanisms to achieve , one set of mechanism is used to put the soil into the pot and take the seedlings, and another set of mechanism is used to realize the planting, the whole mechanism is more complicated
