Problems solved by technology

[0004] Since the two types of paver have their own characteristics and advantages, they are suitable for different working conditions. Need to carry out expressway construction with large width and high flatness requirements), and any one of the paver can not meet the operation needs, you need to buy two paver to meet the needs of different working conditions, resulting in an increase in cost and work inconvenience
At present, the same paver cannot meet the needs of hydraulic telescopic paver and mechanical extension paver at the same time, so a paver that combines the characteristics of the two is needed

Embodiment approach

[0084] Such as Figure 11 As shown, as the first embodiment of the present invention, preferably, the first screed actuator unit 22 includes a plurality of first actuators 25 , and the second screed actuator unit 23 includes a plurality of second actuators 26 , the plurality of first actuators 25 or the plurality of second actuators 26 respectively communicate with the host hydraulic control unit 21 through a plurality of quick joints 24 . A plurality of first actuators 25 may be vibrating motors to vibrate the mechanically extended screed 9, and a plurality of second actuators 26 may be base plate vibration motors, telescopic plate vibration motors, and screed telescopic oil cylinders respectively. Vibration and telescoping of the hydraulically extendable screed 10. Regardless of whether the mechanically extended screed 9 or the hydraulic telescopic screed 10 is installed, multiple first actuators 25 or multiple second actuators 26 communicate with the host hydraulic control...

Abstract

The invention discloses a paver which comprises a host (7), a mechanical lengthened ironing plate (9) and a hydraulic telescopic ironing plate (10), wherein the mechanical lengthened ironing plate (9) and the hydraulic telescopic ironing plate (10) are selectively connected to the host (7). The paver integrates the advantages of a hydraulic telescopic paver and a mechanical lengthened paver, is suitable for the pavement construction operations under various working conditions, and can meet various operation needs.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a paver. Background technique [0002] A paver is a construction equipment mainly used for paving various materials on the base and surface of the road. It spreads asphalt and concrete materials evenly on the road, and pre-compacts them to a certain extent. Shaping to form asphalt, concrete bases or toppings. The paving speed of this equipment is fast, and it can accurately guarantee the thickness, width, camber, flatness and compactness of the paving layer, so it is widely used. [0003] The current paver mainly includes two parts: the main machine and the screed. According to the structure of the screed, the paver is mainly divided into two types: mechanical extension type and hydraulic telescopic type. The widening of the screed of the mechanically extended paver adopts a step-by-step adjustment method. The paving width is large and the flatness is high. However, the pa...
