Combination mechanism of non-circular gear planetary gear train seedling picking assembly and planting assembly

Abstract

The combined mechanism of non-circular gear planetary gear train seedling picking assembly and planting assembly belongs to agricultural machinery; Both the gear and the planting non-circular sun gear are fixedly installed on the frame, and the rotatable non-circular sun gear shaft is coaxially mated and installed in the inner hole of the seedling non-circular sun gear and the planting non-circular sun gear, and the non-circular sun gear The outer end of the shaft is fixedly connected to the outer shell of the planetary gear train, and the non-circular gear seedling picking planetary gear train assembly and the non-circular gear planting planetary gear train assembly are located in the planetary gear train shell cavity, and the axial direction is dislocated; the structure of the mechanism Simple and compact, the connection between seedling picking and planting in the pot is tight and reliable, with high matching precision, good planting quality, high degree of automation, long service life, and scientific and reasonable matching of structural and technical 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
