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

Abstract

The invention discloses a single-degree-of-freedom circular-gear variable-crank seven-link flower transplanting mechanism. The single-degree-of-freedom circular-gear variable-crank seven-link flower transplanting mechanism is used for solving the problem that effects of entering a seedling planting work part at a better attitude and realizing the full automation of a flower transplanting machine are hard to guarantee due to the fact that a double crank mechanism and a planetary gear mechanism can only form one ring-buckle-shaped trajectory. According to the single-degree-of-freedom circular-gear variable-crank seven-link flower transplanting mechanism, a first crank is hinged to one end of a first link; the other end of the first link is hinged to one end of a second link; one end of a third link is hinged to the middle part of the second link, and the other end of the third link is hinged to a sliding block; the sliding block is connected with a second crank through a sliding pair; a driving circular gear is fixed together with the first crank; a driven circular gear is hinged to a machine frame and is engaged with the driving circular gear; a cam is fixedly arranged on the machine frame; the second crank is fixed with the driven circular gear; the sliding block is connected with a sliding slot of the cam through a cam pair. According to the single-degree-of-freedom circular-gear variable-crank seven-link flower transplanting mechanism, double ring-buckle-shaped trajectories can be realized, so that the full automation of the flower transplanting machine is realized, and proper angle and speed for flower seedling casting and verticality of seedling planting 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 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 mecha...

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
