Description

[0001] technical field

[0002] The invention relates to a rice transplanter, in particular to a driving system of the rice transplanter.

[0003] Background technique

[0004] The rice transplanter is one of the most widely used equipment in agricultural production, which greatly reduces the labor intensity of food production, especially rice production. Existing rice transplanters use mechanical transmission without exception, and this transmission method is highly praised for its transmission accuracy and mature technology. However, its complicated transmission mechanism restricts the multifunctional development of the rice transplanter, and also increases its maintenance cost.

[0005] Contents of the invention

[0006] The present invention mainly solves the technical problems of complex transmission mechanism and troublesome layout of the rice transplanter existing in the prior art, which restricts its multifunctional development, and meanwhile has technical probl...
