DETAILED DESCRIPTION

[0038] Referring to Figures 1 to 8 As shown in the figure.

[0039] Embodiment one further illustrates the utility model of a kind of paving construction auxiliary device of recycled asphalt concrete.

[0040] A kind of paving construction auxiliary device of recycled asphalt concrete, including liquid tank 100 and spray pipe 200, still including symmetrically arranged mobile main body 300 and the rotating plate 400 of rotation connection on mobile main body 300.

[0041] Liquid tank 100 is fixedly connected on mobile main body 300, and the surface of rotating plate 400 towards construction ground is provided with liquid flow hole 501, one end of liquid flow hole 501 is communicated with spray pipe 200, and spray pipe 200 is arranged towards construction ground, the other end of liquid flow hole 501 is communicated with the inside of liquid tank 100, and spray pipe 200 is fixedly connected on the lower surface of rotating plate 400, and the recycled agent loaded in liquid tank 100 is sprayed on construction ground by liquid flow hole 501 and spray pipe 200.

[0042] Wherein, the connecting place between the two rotating plates 400 is rotationally arranged, which can adjust the distance between the two mobile main bodies 300.

[0043] In order to help the old and new asphalt materials of the road surface to blend, and ensure the construction quality of the road surface, the regenerative agent needs to be sprayed on the road surface before the recycled asphalt concrete is paved on the road surface. Since the width of the road surface is not equal, and the connecting part between the two rotating plates 400 is rotatably arranged, the angle between the two rotating plates 400 needs to be adjusted, so that the spraying pipe 200 below the rotating plate 400 is just above the construction road surface. Therefore, the application can adjust the angle between the two rotating plates 400 according to the width of the construction road surface, so that the regenerative agent loaded in the liquid tank 100 is sprayed on the construction ground through the liquid flow hole 501 and the spraying pipe 200 before the recycled asphalt concrete is paved on the construction road surface, so as to achieve the purpose of spraying the regenerative agent on the construction road surface. The moving body 300 drives on the construction road surface, so as to spray the regenerative agent at different places of the construction road surface.

[0044] Example two is based on example one and adds the following technical features:

[0045] A paving construction auxiliary device for recycled asphalt concrete, the liquid tank 100 is provided with a liquid inlet hole at the top end, and the liquid inlet hole of the liquid tank 100 is provided with a plug 101.

[0046] The lower part of the moving body 300 is provided with a roller 301.

[0047] When it is necessary to supplement the regenerative agent in the liquid tank 100, the worker removes the plug 101 from the liquid inlet hole at the top end of the liquid tank 100, so as to inject the regenerative agent into the liquid tank 100 through the liquid inlet hole at the top end of the liquid tank 100. Then the plug 101 is installed at the liquid inlet hole at the top end of the liquid tank 100, so as to block the liquid inlet hole at the top end of the liquid tank 100 by the plug 101. Since the lower part of the moving body 300 is provided with a roller 301, the device can move on the construction road surface. Since the moving body 300 is provided with a driving mechanism for driving the roller 301, and the driving mechanism is prior art, it is not described in detail in this application. The roller 301 is driven by the driving mechanism, so as to realize the movement of the device on the construction road surface, and facilitate the spraying of the regenerative agent at different places of the construction road surface.

[0048] Example three is based on example two and adds the following technical features:

[0049] A paving construction auxiliary device for recycled asphalt concrete, the liquid tank 100 is fixedly connected with a liquid pump 102 in the inside, the liquid pump 102 is communicated with a first hose 103 at the liquid outlet end, and the first hose 103 is communicated with the liquid flow hole 501.

[0050] When it is needed to spray the regenerating agent to the construction road surface through the spraying pipe 200, the liquid pump 102 works to realize that the regenerating agent in the liquid tank 100 is sprayed to the construction ground through the first hose 103, the liquid flow hole 501 and the spraying pipe 200, and since the first hose 103 is made of soft material, the rotation of the rotating plate 400 is not affected.

[0051] The embodiment four adds the following technical features on the basis of the embodiment three:

[0052] The paving construction auxiliary device for the regenerated asphalt concrete further comprises:

[0053] The connecting portions between the two rotating plates 400 are locked through the locking bolts 402, and the rotating plate 400 is provided with the bolt holes 403 matched with the locking bolts 402.

[0054] The connecting portions between the two rotating plates 400 are locked through the locking bolts 402, and the rotating plate 400 is provided with the bolt holes 403 matched with the locking bolts 402.

[0055] When it is needed to adjust the angle between the two rotating plates 400 according to the width of the construction road surface, for example, when the width of the construction road surface is small, the worker rotates the locking bolt 402 to detach the locking bolt 402 from the two rotating plates 400, that is, the two rotating plates 400 are not locked at this time, and since the two rotating plates 400 are connected through the rotating shaft 401, the distance between the two mobile bodies 300 is reduced, and the two rotating plates 400 are rotated relative to each other until all the spraying pipes 200 are located directly above the construction road surface, and the regenerating agent sprayed from the spraying pipes 200 can spray the construction road surface with the width, and then the worker reversely rotates the locking bolt 402 to lock the two rotating plates 400 through the locking bolt 402.

[0056] The embodiment five adds the following technical features on the basis of the embodiment four:

[0057] The paving construction auxiliary device for the regenerated asphalt concrete further comprises:

[0058] The heating tank 600 is fixedly connected above the mobile body 300, and the side wall of the heating tank 600 is provided with the air inlet hole 601.

[0059] The heating plate 602 is fixedly connected inside the heating tank 600.

[0060] The blower 700 is fixedly connected to the bottom of the heating box 600. The air inlet of the blower 700 is connected to the heating box 600, and the air outlet of the blower 700 is connected to the first air outlet pipe 701. The first air outlet pipe 701 is connected to the inside of the liquid tank 100.

[0061] The display screen 104 is fixedly connected to the outer wall of the liquid tank 100.

[0062] Temperature sensor 603 is fixedly connected to the inner wall of liquid tank 100. Temperature sensor 603 is connected to display screen 104 for signal transmission. Temperature sensor 603 is used to measure the temperature value of the regenerant inside liquid tank 100 and then upload the temperature value data to display screen 104.

[0063] Control valve 702 is installed on the first air outlet pipe 701.

[0064] To maintain good performance of the regenerant, it is necessary to heat the regenerant to a suitable temperature. The heating plate 602 heats the gas inside the heating box 600, and the fan 700 blows the hot air inside the heating box 600 through the first air outlet 701 onto the regenerant inside the liquid tank 100, thereby heating the regenerant inside the liquid tank 100. Since the temperature sensor 603 can measure the temperature value of the regenerant inside the liquid tank 100 and upload the temperature data to the display screen 104, when the temperature of the regenerant inside the liquid tank 100 reaches a suitable state, the control valve 702 closes the first air outlet 701.

[0065] Example 6 adds the following technical features based on Example 5:

[0066] An auxiliary device for paving recycled asphalt concrete further includes:

[0067] The fixed plate 800 is fixedly connected to the side wall of the rotating plate 400, and the fixed plate 800 has an air outlet 801 on its surface facing the construction ground.

[0068] The second flexible hose 802 is connected to the air outlet 801. Since the second flexible hose 802 is made of soft material, it does not affect the rotation of the rotating plate 400.

[0069] The second air outlet pipe 803 has one end connected to the second flexible hose 802 and the other end connected to the air outlet of the fan 700.

[0070] Temperature detector 805 is installed below the mounting plate 800. Temperature detector 805 is used to detect the temperature value of the construction ground. Temperature detector 805 is connected to display screen 104 and sends the temperature value of the construction ground detected by temperature detector 805 to display screen 104.

[0071] The fixed plate 800 has a first channel 804, and the rotating plate 400 has a second channel 404 inside. The second channel 404 is connected to the first channel 804. The second channel 404 is located above the flow hole 501. A one-way valve 405 is installed inside the second channel 404.

[0072] When the recycling agent is sprayed onto the construction road surface, it is necessary to preheat the construction road surface to ensure the performance of the recycling agent and prevent the recycling agent from cooling down rapidly after being sprayed onto the construction road surface. The heating plate 602 works to heat the gas inside the heating box 600, and the fan 700 works to allow the hot air inside the heating box 600 to enter the air outlet 801 through the second air outlet pipe 803 and the second hose 802. Since the air outlet 801 is set towards the construction road surface, the hot air blown out of the air outlet 801 preheats the construction road surface.

[0073] The temperature detector 805 can measure the temperature of the road surface under construction and transmit the temperature value of the road surface to the display screen 104. Therefore, it is possible to observe whether the temperature of the road surface under construction has reached a suitable temperature. If the temperature has not reached a suitable temperature, the temperature of the road surface can be brought to a suitable temperature by delaying the duration of hot air blowing on the road surface or increasing the heating performance of the heating plate 602 (since the heating plate 602 is equipped with three heating levels, the heating performance can be changed by adjusting the level).

[0074] Since the spray pipe 200 is initially at a low temperature before the regenerant is sprayed, to prevent the regenerant from encountering cold air inside the spray pipe 200, hot air enters the spray pipe 200 through the first channel 804, the second channel 404, and the flow hole 501 to preheat the spray pipe 200. Because a one-way valve 405 is installed inside the second channel 404, the regenerant inside the spray pipe 200 cannot enter the first channel 804 through the flow hole 501 and the second channel 404. When the regenerant subsequently enters the spray pipe 200, the hot air blows from top to bottom into the spray pipe 200, thereby increasing the force with which the regenerant inside the spray pipe 200 is blown onto the construction surface.

[0075] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
