Single-degree-of-freedom non-circular gear variable crank seven-bar flower transplanting mechanism

Abstract

The invention discloses a seven-rod flowers and plants translating mechanism with a variable crank with single degree of freedom and a non-circular gear. A double crank mechanism and a planetary gear mechanism just can form a buckled track, so that the mechanism hardly enters into a seedling planting part in a relatively good posture and full-automation of a flowers and plants translating machine is hardly guaranteed. According to the mechanism disclosed by the invention, one end of a first connecting rod is hinged with a first crank while the other end of the first connecting rod is hinged with a second connecting rod; one end of a third connecting rod is hinged with the middle part of the second connecting rod while the other end of the third connecting rod is hinged with a slide block; a second middle non-circular gear is engaged with a second driven non-circular gear; the second driven non-circular gear is fixed with a second crank; a cam is fixed with a frame, and the slide block is connected with a chute of the cam through a cam pair. The mechanism disclosed by the invention can realize the buckled track so as to realize full-automation of the flowers and plants translating machine, so that the proper seedling dropping angle and speed of flowers and plants and the planting upright degree are guaranteed.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a flower transplanting mechanism, in particular to a single-degree-of-freedom non-circular gear variable crank seven-bar flower transplanting mechanism. Background technique [0002] Mechanized transplanting is generally divided into two steps: taking seedlings and planting. According to different ways of taking seedlings, the transplanting machine is divided into two modes: fully automatic and semi-automatic. The key sign is to see whether it uses mechanized seedling picking. [0003] At present, there are two ways of picking seedlings by mechanical transplanting in dry land and picking seedlings by clamping seedlings. The new planetary gear system rotary seedling picking mechanism includes a hybrid high-order modified elliptical gear planetary system seedling transplanting machine, a free second-order non-circular gear planetary system high-speed pot seedling transplanting m...

AI Technical Summary

Problems solved by technology

[0004] For the double crank mechanism and the planetary gear mechanism, only one ring-shaped trajectory can be formed, and the double-loop-shaped trajectory cannot be realized. It is difficult to ensure that it can enter the seedling planting work part with a better attitude and realize the full automation of the flower transplanting machine. In order to solve this problem, It is necessary to design a ring-shaped trajectory in the seedling planting mechanism to meet the requirements of the flower transplanting trajectory
