Abstract

The invention relates to a digital hydraulic control system for a paver screed, the paver screed using the system and a paver. The digital hydraulic control system comprises a hydraulic power elementand a mechanical feedback type digital servo hydraulic cylinder, wherein the hydraulic power element drives the mechanical feedback type digital servo hydraulic cylinder to move; the mechanical feedback type digital servo hydraulic cylinder controls the spatial position of a screed adjusting mechanism of the paver screed. The equipment use rate of the paver is increased, control is simplified, andthe paving quality can be improved. The mechanical feedback type digital servo hydraulic cylinder is arranged, a feedback adjustment simplified system is adopted, corresponding displacement is generated rapidly and accurately through a hydraulic cylinder, the flatness of the paving process is guaranteed, and therefore the pavement quality of a project is improved.

Description

technical field [0001] The present invention relates to the technical field of special construction machinery for road surfaces, and more specifically, relates to a digital hydraulic control system for a paver screed, a paver screed using the system, and a paver. Background technique [0002] With the development of our country's infrastructure, the quality requirements for high-grade highway pavement are getting higher and higher, and higher requirements are put forward for engineering quality. As the core machinery of highway and urban road construction, the performance of paver has been paid more and more attention by construction units and equipment manufacturers. Paver has become the main means and main equipment to ensure project quality and construction period, reduce project cost and save project construction cost. [0003] The paver is a special construction machine for paving the pavement. Its function is to spread the mixed materials evenly on the subbase of the ...
