Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, a temperature control device for asphalt concrete construction includes a support frame 1, a heating box 2, an insulation box 3, a screw conveyor 4, and a switching mechanism 5.

[0026] like Figure 1 , Figure 2 As shown, the support frame 1 is vertically set on the ground, and the heating box 2 is set on the upper end of the support frame 1. The stirring paddle 21 is horizontally rotatably connected inside the heating box 2 to realize the mixing and heating of asphalt concrete and ensure the uniformity of heating.

[0027] like Figure 1 , Figure 2 As shown, the upper end of the heating box 2 is provided with a feed inlet 22, and a sealing cover 23 is provided on the feed inlet 22. One side of the sealing cover 23 is rotatably connected to the feed inlet 22. A hydraulic cylinder 24 is rotatably connected to the upper end face of the heating box 2, and the piston rod of the hydraulic cylinder 24 is rotatably connected to the sealing cover 23.

[0028] like Figure 1 , Figure 2 As shown, the heat preservation box 3 is located below the heating box 2, the screw conveyor 4 is located below the heat preservation box 3, and the switch mechanism 5 is used to control the opening and closing of the connection positions between the heating box 2 and the heat preservation box 3, as well as between the heat preservation box 3 and the screw conveyor 4.

[0029] like Figure 1 , Figure 2 As shown, the switching mechanism 5 includes a pair of switch plates 51 and a pair of cylinders 52. The pair of switch plates 51 are horizontally slidably connected to the support frame 1 and are used to insert into the connection positions between the heating box 2 and the insulation box 3 and between the insulation box 3 and the screw conveyor 4. The cylinders 52 are used to control the horizontal sliding of the switch plates 51.

[0030] like Figure 1 , Figure 2 As shown, scrapers 6 are provided on both sides of the lower discharge position of the heating box 2 and the heat preservation box 3 to abut against the upper surface of the switch plate 51, so as to scrape the surface of the switch plate 51 when the switch plate 51 slides, and ensure the stable operation of the switch plate 51.

[0031] When it is necessary to heat and store asphalt concrete, the hydraulic cylinder 24 controls the sealing cover 23 to flip, opening the feed inlet 22, and then the asphalt concrete can be poured into the heating box 2. Then, the hydraulic cylinder 24 controls the sealing cover 23 to flip in the opposite direction, closing the feed inlet 22.

[0032] Then, the stirring paddle 21 inside the heating box 2 is started to achieve uniform mixing of the asphalt concrete inside the heating box 2. At the same time, the asphalt concrete is heated by the constant temperature heating wire or constant temperature heating plate inside the heating box 2 to achieve the temperature rise of the asphalt concrete.

[0033] After the asphalt concrete is heated, the cylinder 52 in the upper position is activated, and the switch plate 51 is moved away from each other, so as to realize the connection between the heating box 2 and the insulation box 3, so that the heated asphalt concrete falls into the insulation box 3, and the temperature of the asphalt concrete is maintained by the constant temperature heating wire or constant temperature heating plate in the insulation box 3.

[0034] Subsequently, cylinder 52 controls switch plates 51 to move closer together, sealing the space between heating box 2 and insulation box 3, and enabling the heating of the next batch of concrete. After each batch of concrete is heated, it can be placed in insulation box 3 for heat preservation and storage.

[0035] When it is necessary to lay asphalt concrete, the lower switch mechanism 5 is opened, so that the concrete in the insulation box 3 falls into the screw conveyor 4, and the screw conveyor 4 is used to transport and lay the asphalt concrete.

[0036] Therefore, by setting up a temperature control device that can heat and store asphalt concrete, continuous heating of each batch of asphalt concrete can be achieved, and after heating, it can be transferred to the insulation box 3 for insulation storage, thereby ensuring that asphalt concrete can be laid at any time and continuously without waiting for the asphalt concrete to be heated, thus ensuring construction continuity and improving construction efficiency.

[0037] like Figure 1 , Figure 3 As shown, the heating box 2 includes a box body 25 and a box cover 26. The box cover 26 is fastened to the upper end of the box body 25. The box body 25 is provided with a drive mechanism 7 for controlling the vertical movement of the box cover 26. The drive mechanism 7 includes an upper drive block 71, a lower drive block 72, a guide rod 73, a screw 74, and a motor 75.

[0038] like Figure 3As shown, the upper drive block 71 is horizontally disposed on both sides of the cover 26, and the lower drive block 72 is horizontally disposed on both sides of the housing 25. The guide rod 73 is vertically disposed on one of the lower drive blocks 72 and passes through the upper drive block 71 on the same side. The screw 74 is rotatably connected to the other lower drive block 72 and passes through and is threadedly connected to the upper drive block 71 on the same side. The motor 75 is used to control the rotation of the screw 74.

[0039] When cleaning of the inner wall of the heating chamber 2 is required, the screw 74 is rotated by the motor 75, and the cover 26 is moved upwards by the cooperation of the screw 74 and the guide rod 73, thus opening the cover 26. At this time, the machine can be stopped, and the inner wall of the heating chamber 2 can be easily cleaned. After cleaning, the screw 74 is rotated in the opposite direction by the motor 75, and the cover 26 is moved downwards by the cooperation of the screw 74 and the guide rod 73, thus closing the cover 26.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
