[0021] In order to better understand the purpose, structure and function of the utility model, the automatic asphalt pavement joint processing device of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-4 The utility model: an automatic processing device for asphalt pavement joints, comprises a control box 2 and a shell 4, a screed plate 1 is arranged on the outside of the control box 2, a connecting frame 8 is fixedly connected to the right side of the screed plate 1, the right side of the connecting frame 8 is fixedly connected to the left side of the control box 2, the right side of the control box 2 is fixedly connected to the left side of the shell 4, an embedded computer control terminal 5 and an automatic crack width detector 7 are respectively fixedly connected to the inner wall of the control box 2, a protective door 6 is arranged on the outside of the control box 2, the front side of the protective door 6 is movably hinged to the back side of the control box 2, and the protective door 6 can be used to conveniently seal the outside of the shell 4, thereby effectively increasing the protective effect.

[0023] The detection end of the automatic crack width detector 7 passes through the control box 2 and extends to the outside of the control box 2. The front of the control box 2 is fixedly connected with a lamp holder plate 10 and a first measuring mark 9, and the bottom of the lamp holder plate 10 is fixedly connected with an LED lamp board 11. The inner wall of the outer shell 4 is fixedly connected with a tension spring 12. Two groups of limit plates 3 are arranged on the outside of the outer shell 4. The side surfaces of the two groups of limit plates 3 that are close to each other are fixedly connected with the front and back surfaces of the outer shell 4, respectively. Through the limit plates 3, the limiting effect of the outer shell 4 can be conveniently increased to achieve a better limiting effect.

[0024] The left end of the tension spring 12 is fixedly connected to a clamping plate 13, the left side surface of the clamping plate 13 is in contact with the inner wall of the outer shell 4, the front of the clamping plate 13 is fixedly connected to a second measuring mark 15, and the outer surface of the tension spring 12 is fixedly connected to two connecting rings 18, and the side surfaces of the two connecting rings 18 that are away from each other are respectively fixedly connected to the inner wall of the outer shell 4 and the right side surface of the clamping plate 13. Through the connecting ring 18, the connection of the connecting end of the tension spring 12 can be increased, thereby effectively increasing its fixing effect.

[0025] The inner wall of the outer shell 4 and the inner wall of the clamping plate 13 are rotatably connected with a plurality of identical rollers 16, and the inner wall of the outer shell 4 is fixedly connected with three telescopic rods 17, and the left end of each telescopic rod 17 is fixedly connected to the right side surface of the clamping plate 13. Through the telescopic rods 17, the balance of the clamping plate 13 during the stretching process can be conveniently increased, and the moving effect can be effectively increased.

[0026] The embedded computer control terminal 5 is electrically connected to the automatic crack width detector 7 and the LED light board 11 through wires. Two auxiliary handles 14 are provided on the outside of the clamping plate 13. The side surfaces of the two auxiliary handles 14 close to each other are fixedly connected to the front and back sides of the clamping plate 13 respectively. Through the auxiliary handles 14, the clamping plate 13 can be easily moved to achieve a better auxiliary effect.

[0027] The working principle of the utility model is as follows: first, the control box 2 is directly installed on the side of the ironing plate 1 through the connecting frame 8. When it is necessary to lay asphalt on the edge of the shoulder, due to the inconsistent width of the shoulder edge, the shoulder edge area cannot be completely laid during the asphalt laying process. Then, the clamping plate 13 is pulled outward through the auxiliary handle 14, so that the clamping plate 13 directly cooperates with the inner wall of the shell 4 to clamp the shoulder. At this time, the second measuring mark 15 on the clamping plate 13 and the first measuring mark 9 on the control box 2 are standard widths. The standard width can be continuously monitored by the automatic crack width detector 7. Before use, it can be directly controlled by the embedded computer control terminal 5 sets a variable threshold between the first measuring mark 9 and the second measuring mark 15. The set variable threshold can directly control the unloading speed of the screed plate 1. When the paver controls the screed plate 1 to lay asphalt, the clamping plate 13 and the roller 16 inside the shell 4 can directly roll and move on the shoulder. When the shoulder deviates from the preset laying straight line, the tension spring 12 inside the shell 4 can directly stretch the clamping plate 13 so that the clamping plate 13 can always adhere to the shoulder surface. Due to the deviation of the shoulder, the position of the second measuring mark 15 driven by the clamping plate 13 will also deviate, resulting in a deviation between the first measuring mark 9 and the second measuring mark 15. The width distance between the two increases or decreases, and the crack width automatic detector 7 can detect the deviation value between the first measuring mark 9 and the second measuring mark 15 through the initial value between the two first measuring marks 9 and the second measuring mark 15, wherein the detection result is directly transmitted to the inside of the embedded computer control terminal 5 through an electrical signal, and the embedded computer control terminal 5 can process the deviation value, and directly control the feeding speed inside the ironing plate 1 through the deviation width value. When the deviation value between the asphalt paving and the shoulder increases, the embedded computer control terminal 5 directly increases the feeding amount of asphalt inside the ironing plate 1, and then increases the discharge amount through the ironing plate 1. The asphalt is squeezed toward the shoulder of the road, which changes the paving width of the asphalt by the screed plate 1, and the asphalt output is reduced in turn. The paving width of the screed plate 1 can be effectively adjusted according to the deviation value between the first measuring mark 9 and the second measuring mark 15. When paving at night, the LED light board 11 is directly used to increase the lighting effect, which is convenient for the automatic crack width detector 7 to detect, effectively increasing the automatic detection effect, saving time and effort, and increasing the asphalt paving effect, avoiding the problem that the road paver cannot adjust the spraying amount of the screed plate 1 according to the actual width of the asphalt and the edge of the lane, and the manual adjustment by the naked eye not only increases the difficulty of the work, but also reduces the efficiency of paving the joints.
