Abstract

The invention relates to an electrohydraulic hybrid driving system for a seedling planting machine. The electrohydraulic hybrid driving system comprises a front-wheel driving oil line, a rear-wheel driving oil line, a seedling planting motor and a controller, wherein the front-wheel driving oil line is connected with two front-wheel driving motors between which a front-wheel synchronous valve is arranged; the rear-wheel driving oil line is connected with two rear-wheel driving motors between which a rear synchronous valve is arranged; the front-wheel driving motors and / or the rear-wheel driving motors are provided with rotational-speed sensors; signal circuits of the rotational-speed sensors are connected with the controller; and a control circuit of the seedling planting motor is also connected with the controller. The electrohydraulic hybrid driving system has the characteristics of simple structure, light weight, convenient layout, low failure rate, low maintenance cost and the like.

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...
