[0002] The paver for road construction is an important road construction machinery, which is mainly used for evenly spreading asphalt, cement concrete and other paving materials on the roadbed to form a flat and solid road base or surface layer.
[0003] The paver is usually composed of a hopper, a conveyor belt, a screed, a traveling device and a control system. During operation, the hopper loads paving materials, which are conveyed to the front of the screed by the conveyor belt. The screed is responsible for evenly spreading the paving materials on the roadbed and achieving the required compactness and flatness through vibration or pressing. The height control of the material level in the left and right telescopic sections of the full width telescopic screed seriously restricts the improvement of paving quality. Moreover, due to the imbalance of left and right forces, the material level is too high, which may even cause faults in the left and right telescopic sections. Therefore, it is necessary to ensure a certain material level during paving operation. However, the current traditional telescopic paver screed baffle and the material level in the left and right telescopic sections are adjusted manually or by hydraulic cylinders.
