The invention discloses an ironing plate and a paver, and relates to the technical field of pavement construction machinery. The ironing plate comprises an end telescopic ironing device, the end telescopic ironing device comprises a fixed structure and a telescopic structure in sliding fit with the fixed structure, the telescopic structure comprises a telescopic assembly extending in the first direction and two telescopic frames arranged at the two ends of the telescopic assembly, and the telescopic frames are in sliding fit with the fixed structure; a plurality of sliding grooves extending inthe vertical direction are formed in the telescopic frame at intervals in the second direction, the second direction is perpendicular to the first direction and the first direction and the second direction are both located on a horizontal plane; the telescopic structure further comprises a plurality of connecting pieces and a plurality of adjusting assemblies, and the connecting pieces are movably arranged in the sliding grooves in a penetrating mode in a one-to-one correspondence mode and connected with the telescopic assembly; and the multiple adjusting assemblies are arranged at intervalsin the second direction, the two ends of each adjusting assembly are connected with the telescopic assembly and the telescopic frames correspondingly, and the adjusting assemblies can drive the telescopic assembly to move so that the connecting pieces can slide in the sliding grooves. The height difference and elevation angle adjusting structure of the ironing plate is simple and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of road surface construction machinery, in particular to a screed and a paver. Background technique [0002] The paver is suitable for paving the base and surface of various materials on the road. It is an essential key equipment for building high-grade roads. The screed has been developed rapidly as the main working device of the paver. It has good rigidity and can be flexibly stretched at both ends, and has been widely used. At present, the end telescopic screed in the prior art includes a telescopic frame and a telescopic assembly, but the height difference and elevation angle adjustment structure of the telescopic assembly is complicated, resulting in inconvenient adjustment and affecting the working efficiency. Contents of the invention [0003] The object of the present invention is to provide a screed and a paver, the adjustment structure for adjusting the height difference and elevation angle is s...
