Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than an exhaustive list of all embodiments. And without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.
[0027] The present utility model will be further described below with reference to the accompanying drawings.
[0028] Figure 1 schematizes the structure of a paver 200 according to the present utility model;
[0029] Figure 2 is Figure 1 a partial view of
[0030] Figure 3 is Figure 2 an enlarged view of the position A in
[0031] As Figure 2 and 3 shown, according to a first aspect of the present utility model, there is provided a screeding device for a paver, which mainly includes a screeding plate 13 disposed on a working device of the paver, and an adjusting member disposed between the working device and the screeding plate 13. Preferably, the screeding plate 13 can be used to level the material on the road surface, so as to improve the flatness of the road surface, and further improve the paving quality of the paver 200.
[0032] In an embodiment of the present utility model, as Figure 3 shown, the screeding plate 13 includes a connecting portion 131 connected to the adjusting member, and a screeding portion 132 disposed obliquely below the connecting portion 131. Preferably, the screeding portion 132 can be in direct contact with the material, so that it can more easily perform a screeding operation on the material within the safety area between the leveling device and the road edge during the paving process.
[0033] Preferably, the layout of the material spreading part 132 and the connecting part 131 in the present utility model can effectively increase the contact area between the material spreading plate 13 and the material, so that the material in the safety area between the leveling device and the roadside can be more comprehensively leveled, thereby further improving the flatness of the road surface and the paving quality.
[0034] In one embodiment, as Figure 3 shown, a transition arc surface 133 is formed at the joint of the material spreading part 132 and the connecting part 131. And, the lower end surface of the material spreading part 132 is processed into an arc surface. Therefore, in this way, when the material in the safety area between the leveling device and the roadside is unevenly paved, it can be leveled under the action of the transition arc surface 133 or the material spreading part 132, so as to ensure that the road surface passed by the paver 200 can have higher flatness.
[0035] In one embodiment of the present utility model, as Figure 3 shown, a pressing plate 12 is provided on the working device. Preferably, the material spreading plate 13 is rotatably connected to the pressing plate 12 through a hinge shaft 14. In other words, the material spreading plate 13 is indirectly installed on the working device through the pressing plate 12, thereby improving the flexibility and detachable ability of the material spreading plate 13.
[0036] In other embodiments, the material spreading plate 13 can be directly hinged to the working device. Thus, the material spreading plate 13 can rotate around the working device under the action of the adjusting member, so as to more easily level the material on the road surface to improve the paving quality of the paver 200.
[0037] In the present utility model, the working device includes any one of a screed 201 and a side baffle 202. In other words, the material spreading plate 13 can be selectively installed on the screed 201 or the side baffle 202 according to actual needs.
[0038] Preferably, a limiting member (not shown) for limiting the rotation path of the material spreading plate 13 is provided on the pressing plate 12 or the working device. In the present utility model, the limiting member is, for example, a limiting protrusion. In this way, it can effectively ensure that the material spreading plate 13 rotates adaptively within a limited range, thereby avoiding the situation that the material spreading plate 13 fails due to excessive rotation amplitude, further strengthening the leveling effect on the material and improving the working efficiency, so as to further improve the flatness of the road surface and the paving quality.
[0039] In one embodiment, a fixed seat is provided on the working device, and the end parts of the adjusting member are respectively connected to the fixed seat and the material spreading plate 13.
[0040] As Figure 3As shown, when the fixing seat is fixed on the side baffle 202, the fixing seat can be fixed on the screed 201 through the fastening screw 101. Preferably, the fixing seat is configured as a U-shaped structure and welded to the side baffle 202. Correspondingly, the first end of the fastening screw 101 is fixedly connected to the screed 201, and the second end of the fastening screw 101 is fixedly connected to the connecting part, thereby forming a firm connection relationship among the screed 201, the side baffle 202 and the fixing seat, which is helpful for subsequent plastering operations;
[0041] In an embodiment not shown, when the fixing seat is fixed on the screed 20, the fixing seat is configured as a U-shaped structure and directly welded to the screed 20.
[0042] In the present utility model, the adjusting member is configured as a self-resetting flexible body. Preferably, the adjusting member is, for example, a tension spring 22. Preferably, a hook is also fixed on the fastening screw 101, and the tension spring 22 is arranged between the hook and the plastering plate 13. Preferably, the plastering plate 13 is configured to be able to rotate around the pressing plate 12 under the action of the tension spring 22. During the paving operation, the plastering plate 13 can rotate to a certain extent according to the distribution of the material, so the material (such as asphalt) in the safe area between the screeding device and the road edge will also be further leveled under the action of the plastering plate 13, thereby effectively improving the flatness of the road surface and further improving the paving quality of the paver 200.
[0043] According to the present utility model, as Figure 3 shown, the hook includes a support rod 21 and an adjusting screw 23. Among them, the first end of the support rod 21 is sleeved outside the fastening screw 101 to form a fixed connection, and the second end of the support rod 21 is fixedly connected to the adjusting screw 23. Therefore, the free end of the adjusting screw 23 can be connected to the tension spring 22, so that it is easier to make the plastering plate 13 rotate by a certain angle around the pressing plate 12 through the tension spring 22.
[0044] In an embodiment, locking buckles for forming a lock with the tension spring 22 are provided at the top of the connecting portion 131 where the free end of the adjusting screw 23 is connected to the plastering plate 13. In this way, not only can the tension spring 22 be firmly installed between the adjusting screw 23 and the plastering plate 13, but also the installation and disassembly work can be more easily achieved through the locking method.
[0045] In an embodiment, as Figure 3 shown, the plastering device for the paver further includes a first bolt 102 arranged between the pressing plate 12 and the screed 201. Preferably, a nut adapted to the first bolt 102 is fixed on the upper end surface of the pressing plate 12. Therefore, the relative position between the screed 201 and the pressing plate 12 can be adjusted through the cooperation of the first bolt 102 and the nut, so as to achieve the purpose of jacking up the screeding device.
[0046] In one embodiment, as Figure 3 shown, the plastering mechanism further includes a gasket 15 fixed to the pressing plate 12 by a second bolt 103. Preferably, a first through hole configured as a strip hole is provided on the gasket 15, and a second through hole configured as a circular hole adapted to the first through hole is provided on the side baffle 202. Therefore, through the cooperation of the second bolt 103, the first through hole of the gasket 15 and the second through hole of the side baffle 202, the height of the gasket 15 can be adjusted more easily, which is beneficial to the subsequent smooth progress of the plastering work.
[0047] According to a second aspect of the present invention, a paver is provided, including a working device, and a plastering device provided on the working device according to the above-mentioned plastering device. It should be noted that when the paver is performing paving operations, the plastering devices on both the left and right sides of the road usually perform plastering work individually or simultaneously.
[0048] Currently, during the paving process of existing pavers, due to the need to reserve a safety distance between the screed device and the road edge, there will be uneven paving in some areas on both sides. For example, there will be bulges or ridges in some areas on both sides and depressions or collapses caused by lack of materials.
[0049] Preferably, for the case of bulges or ridges, the plastering device for the paver can directly level the area and take away the excess materials; for the case of depressions or collapses, the plastering device for the paver can fill and level the area with the excess materials carried, thereby effectively improving the flatness of the road surface and further improving the quality and efficiency of the paving operation.
[0050] Compared with the prior art, the advantages of the present invention are as follows:
[0051] Firstly, during the paving process of the present invention, the screeding operation can be performed on the materials within the safety area between the screed device and the road edge through the screed board 13, so that the paver 200 has the ability to perform edge paving.
[0052] Secondly, the screed board 13 in the present invention can rotate at a certain angle relative to the pressing plate 12 under the action of the hinge shaft 14, so that it is easier and more sufficient to level the materials on the ground, thereby further improving the paving quality of the paver 200. In addition, the layout of the plastering part 132 and the connecting part 131 in the present invention can effectively increase the contact area between the screed board 13 and the materials, so that the materials within the safety area between the screed device and the road edge can be more comprehensively leveled.
[0053] Thirdly, since the joints between the material spreading part 132 and the connecting part 131 and the lower end surface of the material spreading part 132 are processed into arc surfaces. Therefore, when the paving of the material in the safety area at the edge of the road by the ironing device is uneven, it can be leveled under the action of the transition arc surface 133 or the material spreading part 132, so as to ensure that the road surface passed by the paver 200 has higher flatness.
