Abstract

The invention provides a paver and a paving control system thereof. The paving control system comprises a power-assisted control valve set, the power-assisted control valve set comprises a power-assisted oil inlet, a first power-assisted oil outlet, a second power-assisted oil outlet, a third power-assisted oil outlet and a fourth power-assisted oil outlet, the first power-assisted oil outlet is connected with a rod cavity of a first lifting oil cylinder, the second power-assisted oil outlet is connected with the rod cavity of a second lifting oil cylinder, the third power-assisted oil outlet is connected with a rodless cavity of the first lifting oil cylinder, the fourth power-assisted oil outlet is connected with the rodless cavity of the second lifting oil cylinder; wherein a first pressure regulator valve and a second pressure regulator valve are arranged in the power-assisted control valve set, the first pressure regulator valve is used for controlling the oil-outlet pressure of the first power-assisted oil outlet and the third power-assisted oil outlet; and the second pressure regulator valve is used for controlling the oil-outlet pressure of the second power-assisted oil outlet and the fourth power-assisted oil outlet. The paving control system solves the problem that the current paver cannot realize anisobaric power-assisted control on a screed in the prior art.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a paver and a paving control system thereof. Background technique [0002] Figure 1 to Figure 3 Shown is the relevant principle of floating, loading and unloading of the screed in the prior art, and its characteristics are as follows: [0003] The working oil source of the lifting cylinder is used as the control oil source for loading and unloading of the screed, and the pressure source control of loading and unloading of the screed is implemented jointly by the electromagnetic reversing valve 1 and the sequence valve 2. When only the screed is floating, the electromagnetic reversing valve 1 is not powered on, and the working oil source of the lifting cylinder directly supplies oil to the control circuit of the lifting cylinder and the hopper cylinder that can be connected in parallel. When loading or unloading is required, the electromagnetic reversing valve 1 is energized...
