Embodiment Construction

[0025] In order to solve the technical problem of unreasonable pressure value setting in the existing decompression control system, the present invention provides a pressure adjustment method for a paver screed decompression device and a paver screed decompression device pressure regulator.

[0026] Such as figure 1 As shown, the pressure regulation method of paver screed pressure reducing device of the present invention comprises:

[0027] Step 101, detecting the position of the leveling oil cylinder of the paver;

[0028] Step 102, adjusting the pressure of the lifting cylinder according to the position of the leveling cylinder.

[0029] Wherein, step 102 includes:

[0030] Step 1, judging whether the position of the leveling oil cylinder is above the set superscript position, if yes, execute step 2; otherwise, execute step 3;

[0031] Step 2, increasing the pressure of the lifting cylinder to end the process;

[0032] Step 3, judging whether the position of the levelin...

Abstract

The invention discloses a pressure adjusting method of a pressure reducing device of a spreading machine screed plate and a device adopting the pressure adjusting method. The method comprises the steps of detecting the position of a leveling cylinder of a spreading machine, and adjusting the pressure of a lifting cylinder according to the position of the leveling cylinder. As the pressure of the lifting cylinder can be automatically adjusted according to the position of the leveling cylinder, the automatic starting of the pressure reducing device and the automatic setting of the pressure of the lifting cylinder are realized, and the pressure adjusting and control of the screed plate is more reasonable.

Description

technical field [0001] The invention relates to the control technology of engineering machinery, in particular to a pressure regulating method and device of a paver screed decompression device. Background technique [0002] In road construction, paver is a kind of construction equipment for paving various materials of road base and surface course. Pavers can be divided into crawler type and tire type. The common ones are gravel pavers and asphalt pavers. [0003] When the paver is performing paving operations, the position of the screed is one of the main factors affecting the paving height of the material. When the moisture content of the material paved by the paver is too high or relatively loose, although the screed can float up and down on the paved material and the working angle increases, due to the existence of its own gravity, the screed will still fall. As a result, the paving height of the material is too low; at this time, the automatic adjustment function of th...
