Design method of flower transplanting trajectory formed by two-stage non-circular gear five-bar drive mechanism

Abstract

The invention discloses a design method for forming a flower transplanting track by a two-stage non-circular gear five-bar driving mechanism. An existing transplanting mechanism track is not suitable for flower transplantation. The design method specifically comprises the following steps: firstly, constructing a two-stage non-circular gear five-bar driving mechanism, and establishing a free end point of a second connecting rod, so as to form a mathematical model of a double-buckle track; then reversely determining angular velocity change rules of a first crank and a second crank through the established mathematical model, designing a two-stage non-circular gear, and verifying whether the two-stage non-circular gear five-bar driving mechanism satisfies existence conditions of the double cranks. According to the design method, the angular velocity ratio of the first crank to the second crank is changed by adopting the two-stage non-circular gear five-bar driving mechanism, the double-buckle track is realized, so as to realize seedling taking and planting motions, the flower transplanting track can be realized, and full automatic transplantation of various crops such as fruits and vegetables can be realized.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a design method of a transplanting track, in particular to a design method of a flower transplanting track formed by a two-stage non-circular gear five-rod driving 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 s...

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
