Description

Technical Field

[0001] This utility model relates to the field of road paving technology, and in particular to a tiered road paver. Background Technology

[0002] Road paving is a crucial step in road construction, directly impacting road quality, lifespan, and driving comfort. Traditional paving equipment typically involves a single paver continuously advancing along the construction direction to spread and initially compact the material. While a single paver can cover a single layer of road surface by advancing continuously in the designated direction, it is essential for multi-layer road paving. A single paver must wait for the previous layer to cool or harden before proceeding with the next layer, extending construction time, reducing efficiency, and hindering the overall speed of road construction.

[0003] Based on this, a tiered road paver is provided. Utility Model Content

[0004] The present invention aims to overcome the defects in the prior art by providing a tiered pavement paver that can pave the road surface in a tiered manner, thereby reducing construction time, improving construction efficiency, and accelerating road construction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a tiered road paver, including a device support, on which paving mechanisms are sequentially arranged, with at least two paving mechanisms, each paving mechanism including a material spreading mechanism and a material pressing mechanism, and a heating mechanism is provided between the paving mechanisms.

[0006] As a preferred embodiment of the present invention, the material spreading mechanism includes a first telescopic mechanism, and a material spreading box is fixedly connected to the telescopic end of the first telescopic mechanism. Both the upper and lower ends of the material spreading box are open, and the opening at the upper end of the material spreading box is larger than the opening at the lower end of the material spreading box.

[0007] As a preferred embodiment of this utility model, the first telescopic mechanism is fixedly connected to the device bracket.

[0008] As a preferred embodiment of this utility model, a second telescopic mechanism is fixedly connected to the material distribution box, and a closing plate is fixedly connected to the telescopic end of the second telescopic mechanism.

[0009] As a preferred embodiment of this utility model, the closing plate can be inserted into the bottom of the material box and achieve a seal on the lower opening of the material box.

[0010] As a preferred embodiment of this utility model, the lower end of the closing plate is provided with an abutting part for abutting against the inner wall of the material box to achieve a seal.

[0011] As a preferred embodiment of this utility model, the pressing mechanism includes a third telescopic mechanism, which is fixedly connected to the device support.

[0012] As a preferred embodiment of this utility model, a rotating seat is fixedly connected to the telescopic end of the third telescopic mechanism, and a pressure roller is rotatably connected to the rotating seat.

[0013] In a preferred embodiment of this utility model, the heating mechanism is fixedly connected to the mounting bracket, and the mounting bracket is fixedly connected to the device bracket.

[0014] As a preferred embodiment of this utility model, the heating mechanism is capable of spraying drying air or drying fire.

[0015] The beneficial effects of this utility model are:

[0016] This invention features at least two paving mechanisms mounted on a support frame. Each paving mechanism includes a material spreading mechanism and a material pressing mechanism, with a heating mechanism between the paving mechanisms. Each paving mechanism, in conjunction with the heating mechanism, can achieve the paving of a single layer of material. The paving mechanisms, arranged sequentially and operating in sequence, can complete the paving of at least two layers of material. Compared to existing technologies, this significantly reduces the time required for automatic material shaping and curing, thereby increasing road construction speed and efficiency.

Heating mechanism. Detailed Implementation

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-7 As shown below, the structure and function of a tiered pavement paver will be described in detail.

[0027] A tiered road paver includes a device support 1, on which paving mechanisms are sequentially arranged. There are at least two paving mechanisms, each including a material spreading mechanism 2 and a material pressing mechanism 3. A heating mechanism 5 is provided between the paving mechanisms.

[0028] In this utility model, there are only two paving mechanisms, and the material pressing mechanism 3 in each paving mechanism is not limited to one.

[0029] In use, the device bracket 1 can be installed on the existing road paver by bolts or other detachable fixing methods, and the road paver can drive the echelon road paver to move. Alternatively, the device bracket 1 can be installed on the existing movable chassis by bolts or other detachable fixing methods, as long as it can drive the echelon road paver to move.

[0030] After the first paving unit completes the first layer of road surface paving, the second paving unit passes by and carries out the second paving on the road surface paved by the first paving unit, thus achieving tiered paving.

[0031] Furthermore, the structure and function of the material spreading mechanism 2 will be described in detail below;

[0032] like Figures 5-6 As shown, the material spreading mechanism 2 includes a first telescopic mechanism 21. A material spreading box 22 is fixedly connected to the telescopic end of the first telescopic mechanism 21 by bolts. Both the upper and lower ends of the material spreading box 22 are open. The opening at the upper end of the material spreading box 22 is larger than the opening at the lower end of the material spreading box 22. The larger opening at the upper end facilitates material feeding, while the smaller opening at the lower end facilitates control of the material output. The first telescopic mechanism 21 is fixedly connected to the device bracket 1 by bolts.

[0033] A second telescopic mechanism 23 is fixedly connected to the material box 22 by bolts, and a closing plate 24 is fixedly connected to the telescopic end of the second telescopic mechanism 23 by bolts.

[0034] The closing plate 24 can be inserted into the bottom of the material box 22 and seal the lower opening of the material box 22, so that no more material will be discharged from the bottom of the material box 22. Furthermore, in order to ensure the feasibility of sealing, the lower end of the closing plate 24 is provided with an abutting part 241 for abutting against the inner wall of the material box 22 to achieve sealing. The abutting part 241 is connected to the closing plate 24 by bolts or welding. Of course, the abutting part 241 can also be connected to the closing plate 24 by other connection methods.

[0035] In use, the paving material is placed in the paving box 22 and discharged into the ground through the opening at the bottom of the paving box 22 to achieve the paving of the material. The first telescopic mechanism 21 is activated. The first telescopic mechanism 21 can be a hydraulic cylinder or an electric push rod. The telescopic end of the first telescopic mechanism 21 drives the paving box 22 to move, thereby adjusting the relative distance between the paving box 22 and the ground.

[0036] When it is necessary to close the lower opening of the material distribution box 22, the second telescopic mechanism 23 is activated. The second telescopic mechanism 23 can be a hydraulic cylinder or an electric push rod. The telescopic end of the second telescopic mechanism 23 drives the closing plate 24 to move downward, so that the closing plate 24 is inserted into the bottom of the material distribution box 22 to close the bottom of the material distribution box 22, ensuring that the material is no longer discharged from the lower opening and no more material is distributed. In order to ensure that the closing plate 24 can completely seal the bottom of the material distribution box 22, the lower end of the closing plate 24 is provided with an abutment part 241 that can abut against the inner wall of the material distribution box 22.

[0037] Furthermore, as the road paver or mobile chassis drives the paving mechanism 2 forward, the paving box 22 can lay the material on the ground.

[0038] Furthermore, the structure and function of the pressing mechanism 3 will be described in detail below;

[0039] The pressing mechanism 3 includes a third telescopic mechanism 31, which is fixedly connected to the device bracket 1 by bolts;

[0040] like Figure 7 As shown, the telescopic end of the third telescopic mechanism 31 is fixedly connected to a rotating seat 32 by bolts, and a pressure roller 33 is rotatably connected to the rotating seat 32 by a bearing with a seat.

[0041] When in use, the third telescopic mechanism 31 is activated. The telescopic end of the third telescopic mechanism 31 drives the pressing roller 33 to move downward, so that the pressing roller 33 comes into contact with the material spread by the paving mechanism 2. Then, as the road paver or the moving chassis drives the pressing mechanism 32 to move forward, the pressing roller 33 compacts the material.

[0042] To ensure that the compaction mechanism 3 can fully compact the material, multiple compaction mechanisms 3 can be set at the rear end of the paving mechanism 2, and the road paver or mobile chassis driving the compaction mechanism 32 can not only move forward, but also move backward, or a combination of forward and backward movements.

[0043] Furthermore, in order to ensure the stability of the connection between each layer of material, a heating mechanism 5 is provided between the paving mechanism and the paving mechanism. The heating mechanism 5 is fixedly connected to the mounting bracket 4 by bolts, and the mounting bracket 4 is fixedly connected to the device bracket 1 by bolts. The heating mechanism 5 can be a blowtorch, a hot air gun or other drying equipment in the prior art.

[0044] Heating mechanism 5 quickly dries each layer of processed material, reducing the moisture content of each layer, reducing the setting time of each layer of material, and increasing work efficiency.

[0045] Furthermore, through the material spreading mechanism 2 and the material compacting mechanism 3 in each paving mechanism, as well as the heating mechanism 5 behind the paving mechanism, during the movement, the material spreading mechanism 2 spreads the material, the material compacting mechanism 3 compacts the material, and the heating mechanism 5 is used to control the moisture. After the first paving mechanism completes the processing of the first layer of the road surface, the second paving mechanism begins the processing of the second layer of the road surface, realizing tiered paving.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0047] Although this document uses numerous reference numerals from the figures, such as device support 1; material spreading mechanism 2; first telescopic mechanism 21; material spreading box 22; second telescopic mechanism 23; closing plate 24; abutment part 241; pressing mechanism 3; third telescopic mechanism 31; rotating seat 32; pressing roller 33; mounting bracket 4; heating mechanism 5, etc., the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
