Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0027] See also Figure 1-3 , an asphalt mixing paving device for road engineering construction, comprising a paving vehicle 1, a connecting frame 2 is installed on one side of the paving vehicle 1, a supporting frame 3 is installed on one side of the connecting frame 2, a squeezing device 4 is slidably connected to the lower end of the supporting frame 3, a digging device 5 is slidably connected to the lower end of the squeezing device 4, the digging device 5 is used to dig raw materials to one end of the squeezing device 4, and both ends of the squeezing device 4 are also installed with a pressing device 7, and the pressing device 7 is used to squeeze the raw materials; The digging device 5 includes a push block 51 slidably connected to the lower end of the extrusion device 4, a block 53 is installed at one end of the push block 51, a vertical plate 52 is slidably connected to one end of the block 53, and the vertical plate 52 can be operably slid to one side. The lower end of the extrusion device 4 is also equipped with a pushing device 6, which includes a fourth cavity 66 arranged in the extrusion device 4, and a shaft rod 64 is slidably connected inside the fourth cavity 66. The shaft rod 64 is connected to the extrusion device 4 through a seventh spring 26. A connecting sleeve 61 is installed at one end of the shaft rod 64, and a push shaft rod 62 is slidably connected to the lower end of the connecting sleeve 61. An L-shaped plate 63 is installed at the lower end of the push shaft rod 62, and the L-shaped plate 63 can be operably slid to one side.

[0028] First, when asphalt is laid on the road, it is not easy for the asphalt raw materials to fill both sides of the curb, which will cause defects on both sides of the road after the road is paved. The existing method generally fills both sides of the road manually, but it consumes a lot of manpower. Second, when the road has an arc, it is very challenging for the driving skills of the asphalt paving vehicle. Once the turning range is too large or too small, it will cause the paving device to not evenly lay the asphalt on the road. In order to solve the above problems, a digging device 5 and a pressing device 7 are provided, and the digging device 5 is used to continuously dig asphalt from the extrusion device 4 to both sides of the road, so as to reduce the defects on both sides of the road, and the pressing device 7 is used to contact the curb. When the paving vehicle 1 turns too large or too small, the pressing device 7 is retracted and extended, so that the pressing device 7 can always contact the curb, which is convenient for the subsequent extrusion of asphalt, thereby cooperating with the digging of the digging device 5 to reduce the possibility of error; The specific working principle is based on Figure 1 As shown, the paving vehicle 1 drives the connecting frame 2 and the supporting frame 3 to move, and the asphalt is transported to the inside of the supporting frame 3 through the conveyor belt inside the paving vehicle 1, and then the asphalt is pressed by the squeezing device 4. Figure 3 As shown, when the support frame 3 pushes the extrusion device 4 to move downward, the push block 51 at the lower end of the extrusion device 4 will drive the vertical plate 52 to slide to the left, and then the vertical plate 52 is slid downward to be inserted into the asphalt, and then the sliding push block 51 is reset, so that the vertical plate 52 digs part of the asphalt to one end of the extrusion device 4, so that a large amount of asphalt is close to the curb, and then the extrusion device 4 is pressed down to complete the asphalt paving. It should be particularly noted that when the curb is too far away from the extrusion device 4, the material cannot be pushed to the curb by sliding and digging with a vertical plate 52, so an L-shaped plate 63 is provided according to Figure 3 As shown, after the vertical plate 52 digs and pushes a portion of the material, the L-shaped plate 63 is slid downward so that the L-shaped plate 63 is inserted into the material, and then the shaft 64 pushes the shaft 62 and the L-shaped plate 63 to slide toward the curb. In this way, when the extrusion device 4 moves away from the curb, most of the material can be pushed closer to the curb again through the L-shaped plate 63, thereby achieving better paving. Example

[0029] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 In this embodiment, a hydraulic rod 9 is also installed at the lower end of the support frame 3, and the lower end of the hydraulic rod 9 is connected to the extrusion device 4; The extrusion device 4 is provided with a first chamber 10 and a pressure relief groove 24, the first chamber 10 and the pressure relief groove 24 are in communication, the first chamber 10 is also connected to a first piston 12, the upper end of the first piston 12 is provided with a first rod 11, the first rod 11 penetrates the extrusion device 4 and is connected to the lower end of the support frame 3, and the size of the first chamber 10 is larger than that of the pressure relief groove 24; A first tube 13, a second tube 14 and a third tube 15 are also installed inside the extrusion device 4. The second tube 14 and the third tube 15 are respectively connected to the first tube 13. One end of the first tube 13 is connected to the first cavity 10, and the other end of the first tube 13 is connected to the inside of the connecting sleeve 61. The extrusion device 4 is provided with a second chamber 18 inside, the second tube 14 is connected to the second chamber 18, the second chamber 18 is also connected to the second piston 19, the second piston 19 is connected to the extrusion device 4 via an eighth spring 25, a push plate 20 is installed at one end of the second piston 19, a connecting plate 17 is installed at one end of the push plate 20, and the connecting plate 17 is connected to the push block 51; A third chamber 57 is further provided inside the extrusion device 4, and a third piston 58 is slidably connected inside the third chamber 57. The third piston 58 is connected to the extrusion device 4 via a second spring 59. A steel cable 55 is installed at one end of the third piston 58. The steel cable 55 passes through the third chamber 57 and the push block 51 and extends to the vertical plate 52. A round wheel 56 is also installed inside the third chamber 57. The steel cable 55 abuts against the round wheel 56. A first spring 54 is installed at one end of the vertical plate 52, and the first spring 54 is connected to the block 53. A U-shaped groove 21 is further provided inside the extrusion device 4, one side of the U-shaped groove 21 is connected to the inside of the second chamber 18, and the other side of the U-shaped groove 21 is connected to the third chamber 57. A through hole is provided on the push plate 20, and the through hole is operably connected to the U-shaped groove 21; A pressure relief chamber 16 is also provided inside the extrusion device 4 , and the pressure relief chamber 16 is communicated with the third chamber 57 .

[0030] In order to allow the push block 51 and the vertical plate 52 to slide quickly to the left, a pressure relief chamber 16 is provided inside the extrusion device 4. When the connecting plate 17 drives the push block 51 to slide to the left, the third piston 58 squeezes the air into the pressure relief chamber 16. according to Figure 5 and Figure 6 As shown, when the hydraulic rod 9 on the support frame 3 pushes the extrusion device 4 to slide downward, since the first rod 11 is connected to the support frame 3, the first piston 12 connected to the first rod 11 will continuously squeeze the air at the upper end of the first piston 12 to the first tube 13, and the first tube 13 will transport the air to the second tube 14, the third tube 15 and the inside of the connecting sleeve 61 respectively. Figure 6, the air is delivered to the second chamber 18 through the second pipe 14, and the second piston 19 is squeezed to slide to one end by air pressure, and the second piston 19 drives the push plate 20, the connecting plate 17 and the push block 51 to slide to one end, and the push block 51 drives the vertical plate 52 to slide. When the push block 51 and the vertical plate 52 slide to the limit, the second chamber 18 will be connected with the U-shaped groove 21, so that the air will enter the third chamber 57 through the U-shaped groove 21, and the third piston 58 is squeezed to slide to the right by air pressure, and the third piston 58 is used to pull the steel cable 55 to slide, and the steel cable 55 is used to pull the vertical plate 52 to slide downward, so that the push block 51 first slides a distance, and then inserts the material through the vertical plate 52, which is convenient for the subsequent pushing of the material; It should be noted that the air is delivered to the interior of the connecting sleeve 61 through the first pipe 13, thereby pushing the push shaft 62 to slide downward, and the push shaft 62 drives the L-shaped plate 63 to be inserted into the material, and then according to Figure 5 As shown, the third tube 15 will deliver air to the regulating chamber 68. Since the circular plate 69 is slidably connected to the regulating chamber 68, as the air pressure in the regulating chamber 68 continues to increase, the air pressure will squeeze the circular plate 69 to slide out of the regulating chamber 68, so that the air enters the fourth chamber 66, thereby pushing the shaft 64 and the connecting sleeve 61 to slide to the right through the air pressure, so that the L-shaped plate 63 pushes the material to the curb again; The specific operating principle is that the L-shaped plate 63 is first squeezed by air to slide and push the material to the curb and the push block 51 slides to the left, the vertical plate 52 is inserted into the material downward, and then the first piston 12 will slide into the pressure relief groove 24, so that the pressure relief groove 24 is relieved, thereby pulling the second piston 19 and the push plate 20 to reset through the eighth spring 25, and the vertical plate 52 is driven to slide to the right by the push plate 20 to push the material, and then when the through hole on the push plate 20 is connected to the U-shaped groove 21, the air in the third chamber 57 will be retained through the U-shaped groove 21, so that the second spring 59 pushes the third piston 58 to reset, and the first spring 54 drives the vertical plate 52 to reset, which does not affect the extrusion device 4 to squeeze the road surface downward. Example

[0031] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-6 In this embodiment, a fourth spring 67 is also installed on the outer surface of the push shaft rod 62, and the fourth spring 67 is connected to the connecting sleeve 61 through the fourth spring 67. An adjusting chamber 68 is also provided inside the extrusion device 4, one end of the adjusting chamber 68 is connected to the third tube 15, and the other end of the adjusting chamber 68 is connected to the fourth chamber 66. A third spring 60 is installed inside the adjusting chamber 68, and a circular plate 69 is installed at the lower end of the third spring 60, and the circular plate 69 can be operably slid to the third chamber 57.

[0032] When the pressure relief groove 24 is depressurized, the push shaft 62 and the shaft 64 will be reset by the fourth spring 67 and the seventh spring 26. Since the vertical plate 52 has pushed most of the material to the bottom of the push block 51 at this time, in order to prevent the L-shaped plate 63 from resetting and pushing the material back again, it is necessary to lift the L-shaped plate 63 to reset it first, and then retract the shaft 64. Figure 5 As shown, a circular plate 69 is slidably connected inside the adjusting chamber 68. When the fourth chamber 66 drives the fourth piston 65 to slide to the left, the air at the fourth piston 65 will squeeze the circular plate 69 to slide upward. Since the gap between the circular plate 69 and the adjusting chamber 68 is small, the air passing through the gap is limited, thereby realizing the slow sliding of the shaft rod 64, and the push shaft rod 62 can be quickly pulled back to its original position by the fourth spring 67. Example

[0033] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-7 In this embodiment, the pressing device 7 includes an adjusting block 71 and a third plate 78 slidably connected to one end of the extrusion device 4, a first connecting device is installed on the upper end of the third plate 78, one end of the first connecting device is connected to the second plate 75, one end of the second plate 75 is connected to the second connecting device, and one end of the second connecting device is connected to the first plate 72; The first connecting device has the same structure as the second connecting device. Both the first connecting device and the second connecting device include a connecting column 73, a circular sleeve 74 and a third plate 78. The outer surface of the connecting column 73 is rotatably connected with the circular sleeve 74. The lower end of the connecting column 73 is also equipped with a fifth spring 76. A sixth spring 77 is installed inside the extrusion device 4 , and the sixth spring 77 is connected to the adjustment block 71 . The upper end of the adjustment block 71 is also slidably connected to a plug post 8 , and the plug post 8 passes through the extrusion device 4 and the adjustment block 71 .

[0034] The first plate 72 is driven by the extrusion device 4 to extrude the material, thereby realizing the extrusion process during paving. When the running route of the paving vehicle 1 is misaligned with the curb, the sixth spring 77 pushes the adjustment block 71 to slide, so that the adjustment block 71 always contacts the curb, and when the adjustment block 71 slides, the adjustment block 71 will pull the first plate 72 and the connecting column 73 to slide to the right, and then pull the second plate 75 and the third plate 78 to move through the connecting column 73, and compress the fifth spring 76 through the third plate 78 and the second plate 75, so that the third plate 78 and the second plate 75 are flush with the first plate 72, thereby extending the extrusion surface of the first plate 72. In this way, when the road has an arc, the asphalt paving vehicle turns too large or too small, and the asphalt can still be evenly laid on the road through the cooperation of the pressing device 7 and the pushing device 6. Example

[0035] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-9 In this embodiment, the slider 23 is slidably connected inside the extrusion device 4, the fourth cavity 66 is arranged inside the slider 23, and a welding frame 22 is installed on one side of the adjustment block 71. One end of the welding frame 22 is connected to one end of the slider 23, and the welding frame 22 can operably drive the slider 23 to slide.

[0036] according to Fig. 9 As shown, when the adjustment block 71 slides to adjust the extrusion area of ​​the first plate 72, the adjustment block 71 will also drive the welding frame 22 to slide, and pull the slider 23 to slide to the right through the welding frame 22, so that the slider 23 will drive the shaft rod 64 and the connecting sleeve 61 to slide to the right, so that when the L-shaped plate 63 slides to push the material, the L-shaped plate 63 can push most of the material to the lower end of the first plate 72, so as to cooperate with the sliding of the vertical plate 52, thereby improving the paving effect and reducing the material from being evenly laid on the curb.
