Description
Technical Field
The invention belongs to the field of transmission structures of rice transplanters, and particularly relates to a rear axle transmission mechanism of a small rice transplanter.
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.
The rear axle mechanism of the existing rice transplanter has more components and complex structure, and in order to ensure the stability during steering in the four-wheel drive rice transplanter, the rear axle generally needs to be provided with a differential mechanism, so that the integral structure is more complex, in addition, the more complex the structure, the higher the failure probability of the components is, and even the use is influenced.
