Research advances in transplanting mechanism of rice transplanter;

Since the shortage of traditional design method on transplanting mechanism of high speed crank rocker style, this paper makes an elastic dynamic analysis of the mechanism.

Transplanting mechanism with planetary elliptic gears is one kind rotary transplanting mechanism which is assembled on the high speed transplanter, it is the main part of a transplanter, and the trail and pose of its needles to take seedlings determines its performance.

Innovation of the separating planting mechanism is one of key technologies to innovate rice transplanter.

In this paper, a kind of separating planting mechanism of high performance rice transplanter, separating planting mechanism with double control unit was introduced, in order to achieve the movement trace of transplanting arm, connected rod mechanism and planetary rod mechanism were used.

The separating planting mechanism with planetary elliptic gears of high performance rice transplanter made in Japan could not meet the agronomic demand in South China.

The emulate analysis of ellipse gear drive is the key of dynamic emulate of the high-speed separating-planting mechanism ,Now the common emulate software doesn’t supply non-circular gear drive’s emulate analysis tool, so it’s a urgently problem to solve ellipse gear drive emulate analysis .

Advances in rotary transplanting mechanism and analysis methods of its dynamics;

Based on the kinematics of fulfilling transplanting and parameters optimization of dynamics, the check of motion interference for rotary transplanting mechanism is the process of choosing the optimal parameters.

It is difficulty to analyze the kinematics of multi-rigid-body system with traditional means,a dynamic simulation for tramplanting mechanism on High Density Baler was proposed with the multi-body system Simulation and analysis software(ADAMS) Then the optimum dimensions of components satisfing the design demand were acquired.
