Non-circular gear planetary gear train seedling-picking assembly and transplanting assembly combined mechanism

Abstract

The invention discloses a non-circular gear planetary gear train seedling-picking assembly and transplanting assembly combined mechanism, and belongs to the field of agricultural machinery. The mechanism comprises a non-circular gear seedling-picking planetary gear train assembly and a non-circular gear transplanting planetary gear train assembly. A seedling-picking non-circular sun gear and a transplanting non-circular sun gear are fixedly installed on a machine frame. A non-circular sun gear shaft is rotatably and coaxially inserted and installed in inner holes of the seedling-picking non-circular sun gear and the transplanting non-circular sun gear. The outer end of the non-circular sun gear shaft is fixedly connected with a planetary gear train outer housing. The non-circular gear seedling-picking planetary gear train assembly and the non-circular gear transplanting planetary gear train assembly are positioned in a cavity of the planetary gear train outer housing, and axially disposed in a mismatch mode. The mechanism is simple and compact in structure, tight and reliable in cohesion of pot seedling-picking and transplanting operation processes, high in cooperation precision, good in transplanting quality, high in automation degree, long in service life, and scientific and rational in matching of structural technology key elements.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a pot seedling picking and planting mechanism on a pot seedling transplanting machine which adopts a combination of a non-circular gear seedling picking planetary gear train assembly and a non-circular gear planting planetary gear train assembly. Background technique [0002] The planting system of the planetary gear system applied to pot seedling transplanting researched by Zhejiang Sci-Tech University is composed of two sets of non-circular gear planetary gear trains that are independently formed and arranged. During operation, one of the non-circular gear planetary gear Seedling picking and conveying operations, another set of non-circular gear planetary gear train mechanism completes seedling planting operations. Due to many reasons such as the complex configuration structure of the two sets of mechanisms on the machine tools, large external dimensions, low operation coordinatio...

AI Technical Summary

Problems solved by technology

Due to many reasons, such as the complex structure of the two sets of mechanisms on the equipment, the large size, the low precision of the operation, and the poor quality of the pot seedlings, they have not been popularized and applied in the practice of production operations.

In addition, incomplete gears are installed and used in the two sets of mechanisms, which cause the planetary gear system to be easily worn and the service life of the mechanism is short
