Abstract

The invention discloses an eccentric gear-incomplete non-circular gear planetary gear plug seedling picking mechanism. Power inside a sprocket box is transmitted to a center shaft, one end of which is fixed with a gear box. Longitudinally symmetrical planetary gear mechanisms are installed inside the gear box. An upper and lower planetary shaft that extend out of the gear box are respectively equipped with a seedling pickling arm of the same structure. An incomplete non-circular gear inside the gear box is fixed at one side of the sprocket box and is engaged with an upper and a lower eccentric gear respectively, and the upper and a lower eccentric gear are engaged with an upper and a lower planetary non-circular gear respectively. The incomplete non-circular gear is in coaxial and fixed connection with a convex locking arc, and the upper and the lower eccentric gear are coaxially in fixed connection with an upper and a lower concave locking arc respectively. In the invention, two sets of planetary gear transmission mechanisms are arranged relative to the center shaft, and set drives the motion of a seedling picking arm. Each circle of turning by the gear box can realize twice seedling picking. The plug seedling picking mechanism of the invention has the advantages of high operation efficiency, simple structure, small volume, light weight, and small vibration.

Description

Eccentric gear-not exclusively the seedling seedling picking mechanism is coiled in the non-circular gear planetary gear system cave
Technical field
The present invention relates to agricultural machinery, especially relate to a kind of eccentric gear-incomplete non-circular gear planetary gear system cave dish seedling seedling picking mechanism of automatic potted-seedling picking machine.
Background technology
At present, potted tray seedling transplanter both domestic and external all be with automanual be main, semi-automatic potted tray seedling transplanter leans on the artificial seedling of feeding, operating efficiency is not high, when planting speed is higher, leaks seedling, missing seedling rate increases greatly.And automatically potted tray seedling transplanter has and gives seedling automatically, gets seedling, comparatively automation and laborsavingization, high efficiency.Though automatic potted tray seedling transplanter structure relative complex, in today that science and technology is maked rapid progress, automatic potted tray seedling transplanter will be a transplanter main development tendency from now on.If on semi-automatic potted tray seedling transplanter, installing this additional, to overlap automatic cave dish seedling seedling picking mechanism be exactly automatic potted tray seedling transplanter.If soil property softer (like paddy field), this cover mechanism is exactly the full-automatic potted tray seedling transplanter of a cover, is promptly all accomplished by this cover mechanism to the seedling of planting from getting seedling.
Summary of the invention
The purpose of this invention is to provide a kind of eccentric gear-incomplete non-circular gear planetary gear system cave dish seedling seedling picking mechanism, the physical dimension of this mechanism is less relatively, and structure is simple relatively, vibrates also little.
