Spreading machine and ironing device thereof

Abstract

The invention provides a spreading machine and an ironing device thereof. The ironing device comprises a basic ironing plate, a lengthening ironing plate which is connected with the basic ironing plate and a clamping mechanism, wherein the clamping mechanism comprises a driving system, a power system, an energy storage system and a limit adjustment system; the driving system comprises a cylinder body, a piston and a supporting rod; the supporting rod passes through the basic ironing plate and the lengthening ironing plate; a first end of the cylinder body is pressed against the lengthening ironing plate; the power system comprises a pressure source which is communicated with the cylinder body; the energy storage system comprises a spring component; a first end of the spring component is pressed against a second end of the cylinder body; the limit adjustment system comprises a first limit adjustment part; and the first limit adjustment part and the supporting rod are provided with a first position which passes through the basic ironing plate and a second position which is pressed against the basic ironing plate. The spreading machine comprises the ironing device. When the ironing plate is lengthened, the spreading machine and the ironing device are easy to mount, and fastening pieces are not required to be screwed up manually, so that the labor intensity of operators is reduced, and the mounting speed of the lengthening ironing plate is increased.

Description

technical field [0001] The invention relates to the field of road construction machinery, more specifically, to a paver and a screed device thereof. Background technique [0002] The screed is the working device of the paver. It is arranged at the rear of the paver and is responsible for the initial compaction and screed of the mixture. The operation function and quality of the paver are finally realized by the screed device. . [0003] Such as figure 1 and figure 2 As shown, the screed is mainly composed of a basic screed 10' (the basic screed of the retractable screed includes a main screed and a secondary screed), extended screeds 40' of different specifications and lengths, etc., the basic screed 10' and The extended screeds 40' are distributed symmetrically. Both the basic screed 10' and the extension screed 40' comprise end plates and a base plate 83', wherein the extension screed 40' has end plates on both sides for connection. in such as figure 1 On the advanc...

AI Technical Summary

Problems solved by technology

[0008] 2. The weight of the extended screed is very heavy, the pre-tightening force of the connecting bolts is relatively large, and the labor intensity of the operator is very high

[0009] 3. Due to the limited operating space of the wrench, the pre-tightening force of the mounting bolts at the front of the screed is smaller than that of others, and they are easy to loosen, which affects the overall rigidity of the screed, thereby affecting the paving quality of the road surface
