Background technology
Paver at present for highway construction is main mainly with stabilized soil paver and multifunctional spreading machine greatly, when pave Stabilized Soil material time, because laying is thicker, spiral distributor is needed to provide more material spreader, at this moment just need to strengthen the distance between screed and spiral distributor, change the method for the elevation of material spreader to meet the supply of material.But the distance between most of paver screed and spiral distributor is changeless, the screed draft arm on paver is one, and its length can not adjust.Therefore the method usually adopted is that screed and draft arm joint face add backing plate to adjust the spacing of spiral distributor and screed, this method adjustment amount is very little, high compactness requirement is not reached when laying is thicker, affect spreading quality, the connection of demolition, installation draft arm and screed is also inconvenient, and simultaneously the unstability of draft arm causes that the paving effect of paver is bad, compactness is not high.Therefore, the paver that a kind of good stability, compactness are high, paving width is adjustable is now needed.
Summary of the invention
Problem to be solved in the utility model is to provide the adjustable paver of a kind of paving width, and this paver structure is simple, reliability is high, advanced in performance, easy and simple to handle, economical and practical, spreading evenness is high; Be widely used in town road, sidewalk, cycleway, indoor engineering, farm road, plant area road, small area face engineering etc.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The paver that a kind of paving width is adjustable, comprise main frame, screed main body, hydraulic telescopic type screed, described hydraulic telescopic type screed, described screed main body is connected on described main frame, two described hydraulic telescopic type screeds are installed on the left and right sides of described screed main body, the left and right sides of described main frame is respectively arranged with draft arm, described main frame is connected with described draft arm by linkage, described linkage comprises drawing cylinder and support arm, one end of described drawing cylinder is articulated with on described support arm, the other end is connected with described draft arm, described draft arm is connected by jointed shaft with described hydraulic telescopic type screed, described draft arm comprises main draft arm and two rear haulage arms, described main draft arm is connected with U-shaped described two rear haulage arms by jointed shaft, described rear haulage arm is connected with described hydraulic telescopic type screed by multiple securing member, described rear haulage arm is provided with connecting hole, described hydraulic telescopic type screed comprises anti-recking means for cargo, described anti-recking means for cargo is arranged on the rear side of described screed main body along the width of described screed main body about the center line symmetry of screed main body.
Described drawing cylinder is other is provided with retaining mechanism.
Aperture and the described securing member of described connecting hole match.
The center line of the described screed main body on two described draft arm edges is arranged symmetrically with.
Angle between the width of described rear haulage arm and described screed main body is 25 °-75 °.
The utility model arranges two draft arms in the center line bilateral symmetry of screed main body, the controller of paver can come to apply tightening force to screed main body by regulating two draft arms, and being directly connected with hydraulic telescopic type screed is that U-shaped rear haulage arm can improve its reliability of drawing, by arranging anti-recking means for cargo to reduce flexural deformation and the torsional deflection of screed main body, even make it not deform, the utility model has that structure is simple, reliability is high, advanced in performance, easy and simple to handle, economical and practical, spreading evenness advantages of higher; Be widely used in town road, sidewalk, cycleway, indoor engineering, farm road, plant area road, small area face engineering etc.
