[0043] Example

[0044] This embodiment provides a paving machine, see Figure 1 , Figure 2 and Figure 3The paver includes a paver body 010, a scraper 030 and an attached vibration device 050. Two attached vibration devices 050 are respectively arranged on both sides of the scraper 030. The paver body 010 includes a driving device. The driving device drives the attached vibration device 050 to vibrate. The attached vibration device 050 beats and shapes the side surfaces of the paving road layer on both sides of the scraper 030.

[0045] The attached vibration device 050 includes a vibration body and a connecting plate 100 for connecting to a paver; the vibration body includes a vibration machine 200, a vibration plate 300 and a vibration reinforcement assembly 400;

[0046] Specifically, the connecting plate 100 is fixedly connected to the vibration body; the vibration plate 300 has a working surface 301 and a mounting surface 303 that are arranged opposite to each other. The vibration machine 200 of the vibration body is fixed to the mounting surface 303 by bolts, and in some embodiments, it can also be directly welded to the mounting surface 303 to ensure the reliability of the connection. The vibration reinforcement component 400 is also arranged on the mounting surface 303.

[0047] The working surface 301 is used to hit the side of the paving layer laid by the paver, and the side of the paving layer is plasticized by the hitting of the working surface 301. Since the thickness of the paving layer determines that the space for installing the vibrator 200 on the vibration body is not enough to install a high-power vibrator 200, and the installation of an ultra-high-power vibrator 200 also requires the paver body 010 to have sufficient electric drive to drive it, which easily causes energy waste.

[0048] In order to provide sufficient impact force through the relatively small power vibrator 200, the vibration reinforcement assembly 400 is installed to achieve vibration reinforcement. Specifically, the mounting surface 303 of the vibration plate 300 is used to install the vibrator 200 and the vibration reinforcement assembly 400; the vibration reinforcement assembly 400 includes a first spring 410 for absorbing and storing vibration energy. The vibration reinforcement assembly 400 absorbs the overflowed vibration energy and releases it in the subsequent process, thereby enhancing the impact force of the vibration body, so as to shape the harder paving road layer.

[0049] In order to realize the installation of the first spring 410, the vibration reinforcement assembly 400 further includes a mounting plate 430; the mounting plate 430 is mounted on the mounting surface 303 through a telescopic rod 450, and the mounting plate 430 is fixedly connected to the connecting plate 100;

[0050] An installation space is formed between the installation plate 430 and the vibration plate 300 . One end of the first spring 410 acts on the installation plate 430 , and the other end acts on the vibration plate 300 .

[0051] When vibrating, the vibrator 200 causes the vibration plate 300 to quickly hit the paving layer. After the vibration plate 300 is blocked by the paving layer and stops suddenly, the first spring 410 will shrink sharply to collect vibration energy, and will partially release it during the next impact, and then absorb the next vibration energy. This reciprocating cycle allows energy that would have been wasted (this energy should have been released as heat energy or released in the form of noise by the vibration plate 300 making ineffective small-amplitude rapid vibrations) to be effectively utilized, thereby increasing the plastic effect of the side of the paving layer.

[0052] In order to help the first spring 410 absorb energy, the vibration reinforcement assembly 400 further includes a weight block 470 ; the weight block 470 is disposed on a side of the mounting plate 430 away from the vibration plate 300 .

[0053] In this embodiment, the weight block 470 is positioned and installed by means of a positioning plate 490. The positioning plate 490 is fixedly arranged on a side of the mounting plate 430 away from the vibration plate 300. The weight block 470 is installed between the positioning plate 490 and the mounting plate 430. A second spring 420 is arranged between the weight block 470 and the mounting plate 430 or the positioning plate 490.

[0054] In this embodiment, the second spring 420 has a relatively weak elastic force, and its main purpose is to reduce noise, and it basically has no function of storing energy.

[0055] Specifically, the positioning plate 490 is installed on the mounting plate 430 through the positioning rod 440; one end of the positioning rod 440 is fixedly set on the mounting plate 430, and the other end is provided with a threaded section, and the positioning plate 490 is provided with a positioning through hole for the threaded section to pass through; a nut is provided on the threaded section.

[0056] To facilitate the installation of the second spring 420, a first protrusion is provided on the side of the positioning plate 490 facing the weight block 470, and a second protrusion is provided on the side of the weight block 470 facing the positioning plate 490. The first protrusion and the second protrusion are respectively arranged on the inner sides of the two ends of the second spring 420.

[0057] In this embodiment, the working surface 301 is evenly distributed with a plurality of convex points, and the height of the convex points is less than 30 mm. The convex points can play a part of the flattening effect while beating, thereby improving the final aesthetics.

[0058] Specifically, the first springs 410 are provided in plurality, and a central space is formed between the plurality of first springs 410, and the vibration machine 200 is installed in the central space, so that in actual work, the plurality of first springs 410 can uniformly absorb energy and uniformly release energy.

[0059] In this embodiment, the attached vibration device 050 is fixedly connected to the paver body 010 by bolts. Specifically, the connecting plate 100 is provided with mounting through holes for mounting the bolts.

[0060] The bolts are fixed on the paver body 010 through the mounting through holes. For safety reasons, pin holes can be opened on the bolts to install pins.

[0061] Since the angle of the side wall of the paving layer may be different in different situations, it is also necessary to adjust the angle of the vibration plate 300. In this embodiment, the angle adjustment is achieved by a wedge-shaped adjustment frame 110.

[0062] Specifically, the wedge-shaped position adjustment frame 110 includes a first plate and a second plate connected at an acute angle. The first plate of the wedge-shaped position adjustment frame 110 is provided with a position adjustment through hole corresponding to the installation through hole. When the attached vibration device 050 is actually installed, the corresponding wedge-shaped position adjustment frame 110 is clamped between the connecting plate 100 and the paver body 010, the position adjustment through hole and the installation through hole are aligned, and then bolts are installed to fix the wedge-shaped position adjustment frame 110 with the attached vibration device 050. The second plate of the wedge-shaped position adjustment frame 110 is provided with a through hole for fixing with the paver body 010. The wedge-shaped position adjustment frame 110 is clamped therein so that there is a certain angle between the connecting plate 100 and the paver body 010, and the clamping angle between the vibration plate 300 and the paver is indirectly adjusted.

[0063] After the attached vibration device 050 is fixed, the vibration machine 200 of the attached vibration device 050 is electrically connected to the driving device.

[0064] The paver provided by the present invention can plasticize the side of the paving layer while paving concrete, which ensures the strength of the paving layer on the one hand, makes the paved paving layer beautiful on the other hand, and saves materials. The enhanced vibration component in the attached vibration device 050 can absorb and release the vibration energy of the vibrator 200 as required, which improves the utilization efficiency and strengthens the plastic effect on the one hand, and reduces the noise output on the other hand. The vibration plate 300 with adjustable angle can match the paving layers with different requirements to plasticize at the required angle.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
