Background
A rice transplanter is an agricultural machine for planting rice seedlings into rice fields. When planting, firstly, a mechanical claw takes out a plurality of rice seedlings from a seedbed and plants the soil in a field, and in order to keep the angle between the seedbed and the ground at a right angle, the front end of the mechanical claw must adopt an elliptic action curve when moving. The motion is completed by a planetary mechanism of a rotary or deformation gear, and the advancing engine can drive the motion machines at the same time. The rice transplanter must have anti-slip wheels and a floating design when moving on the soil. If the seedlings are cut into pieces, the rice seedlings are taken out from a specific seedling box and then planted in a mechanical mode.
