[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0045] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] In the description of the present application, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of the product of the present application when it is usually placed, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0047] In addition, if the terms "first", "second", "third" and the like appear, they are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0048] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0049] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0050] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0051] It should be understood that when constructing roads in hot and rainy areas, due to the high ground temperature and the rain, rainwater will remain on the ground after the rain stops. At this time, if the asphalt is heated and paved, the rainwater on the ground will be affected by the high temperature of the ground and will enter the asphalt. In addition, the rainwater will also penetrate into the asphalt when it comes into contact with the asphalt, causing moisture to accumulate inside the asphalt. Under high temperature conditions, this moisture will accelerate the oxidation reaction of the asphalt, resulting in a decrease in the performance of the asphalt. In addition, if the asphalt is heated and paved after the rainwater on the ground increases, it will take a lot of time, thereby delaying the construction period.

[0052] In order to improve the above problems, Figure 1 As shown, this embodiment provides an asphalt heating device for road construction in hot and rainy areas, which mainly includes a base plate 100, multiple rollers 200, a heating box 300, a heating sleeve 400 and a water absorbent 500.

[0067] In this embodiment, as shown in Figure 1 , the drying device 600 and the water absorption device 500 are arranged close to the discharge valve 330, and the drying device 600 is arranged between the water absorption device 500 and the discharge valve 330, so that the device sequentially performs water absorption and drying operations on the ground, thereby making the ground relatively dry and reducing the influence of rainwater on asphalt.

[0068] In this embodiment, the ground is water-absorbed and dried by the water-absorbing element 500 and the drying element 600, so that the ground has less rainwater, thereby improving the influence of rainwater on asphalt during paving.

The feeding valve 320 and the discharging valve 330 are both openable and closable valve pipelines. In this embodiment, the heating box 300, the heat insulation layer 900, the exhaust member 1000 and the purification box 2000 are separated from the outside by the heat insulation box 3000, so that the above-mentioned components are not affected by the high-temperature environment of the outside, and the power increase or damage of the components is avoided.

Specifically, one end of the temperature sensor 5000 and the pressure sensor 5100 are arranged in the heating box 300 for monitoring the temperature and pressure in the heating box 300. When the temperature sensor 5000 monitors that the temperature in the heating box 300 reaches a preset value, the heating part stops heating or reduces the power to keep the heating box 300 warm. When the temperature sensor 5000 monitors that the temperature in the heating box 300 is lower than the preset value, the heating sleeve 400 heats the heating box 300 until the temperature in the heating box 300 reaches the preset value.

[0087] In this embodiment, when the pressure sensor 5100 monitors that the pressure in the heating box 300 is lower than the preset value, the pressure regulating part 4000 starts, and the exhaust part 1000 stops, so as to pressurize the heating box 300. When the pressure reaches the preset value, the pressure regulating part 4000 stops pressurizing, and the exhaust part 1000 starts, so as to ensure that the gas after heating of the asphalt in the heating box 300 is discharged.
