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.

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.

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.
