Abstract

The invention relates to the technical field of agricultural machinery, in particular to a harvester header lifting and traveling steering parallel control energy-saving valve bank which comprises a steering control unit, a working unit, an oil inlet pipeline and an oil return pipeline, and the working unit comprises a header oil cylinder and a working control valve; the steering control unit comprises a left steering cylinder, a right steering cylinder and a steering control valve; a first overflow branch and a second overflow branch are connected between the oil inlet pipeline and the oil return pipeline, a main overflow valve is arranged on the first overflow branch, a steering overflow valve and a hydraulic control valve are arranged on the second overflow branch, and the set pressure of the steering overflow valve is smaller than that of the main overflow valve. According to the invention, the highest pressure of the system is taken during independent lifting operation of the header, and the low pressure set by the steering system is taken during independent turning operation of the system, so that energy-saving control is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an energy-saving valve group for parallel control of the header lifting and driving steering of a harvester. Background technique [0002] As the country implements the modernization of agricultural machinery, users have higher and higher requirements for agricultural machinery. Domestic harvesters cannot realize the rise and fall of the header when walking and turning, and the operating efficiency is low, and the relief valve of the existing hydraulic system Only one, the maximum pressure of the system cannot be set according to the working conditions, and energy saving cannot be realized. Contents of the invention [0003] In order to solve the problem in the prior art that the maximum pressure of the system cannot be set according to the working conditions, the present invention provides an energy-saving valve group for parallel control of the header lifting a...
