Hydraulic system of full hydraulic seedling planting machine

Abstract

The invention relates to a hydraulic system of a full hydraulic seedling planting machine. The hydraulic system comprises an oil tank, an oil pump, a plurality of electromagnetic valves, a plurality of motors, a front wheel driving oil circuit, a back wheel driving oil circuit and a planting oil circuit, wherein the front wheel driving oil circuit is connected with two front wheel driving motors; a synchronous valve is arranged between the two front wheel driving motors; the back wheel driving oil circuit is connected with two back wheel driving motors; a synchronous valve is also arranged between the two back wheel driving motors; and the planting oil circuit is connected with a planting motor. The hydraulic system has the characteristics of simple structure, lightest weight, convenience in layout, low failure rate and low maintenance cost, and a foundation is laid for multifunctional development of the seedling planting machine.

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...
