[0037] The utility model will be further described below with reference to the drawings.

[0038] Figure 1 The structure of the paver according to the utility model is schematically shown.

[0039] Figure 2 For Figure 1 The partial view shows the positional relationship between the monitoring mechanism 30 and the first screed 20.

[0040] As Figures 1-2 According to the first aspect of the utility model, a road surface height difference adjusting device for a paver is provided, mainly comprising a paver main body 10, and a first screed 20 arranged on one side of the paver main body 10. Wherein, the first screed 20 comprises a screed main body 21, and a first screed plate 22 arranged on the screed main body 21. Preferably, during the paving process, the paving material is compacted under the action of the first screed plate 22 to form a paving road surface.

[0041] Preferably, a second screed is arranged on the paving body 10, and during the paving process, the paving material is also compacted by the second screed to form the paved road surface.

[0042] At present, the paving machine has the problem of affecting the paving quality during the paving process, that is, the height difference (step difference phenomenon) between the paved road surface formed by the first screed mechanism 20 and the paved road surface formed by the paving body 10, which causes the water divide mark on the paved road surface and seriously affects the quality of the road surface, and this height difference often occurs when the width of the paved road changes or the speed of the paving machine changes or the paving machine turns outside.

[0043] Therefore, in order to solve these problems, the utility model sets the monitoring mechanism 30 and the step difference adjusting piece on the screed body 21, which will be described and explained in detail below.

[0044] Figure 3 It is a front view of the monitoring mechanism 30. Figure 4 It is a right view of the monitoring mechanism 30.

[0045] According to the utility model, as shown in the figure, the road surface height difference adjusting device for the paving machine further comprises a monitoring mechanism 30. Figures 2-4 Preferably, the monitoring mechanism 30 comprises a fixing piece arranged on the screed body 21, an induction plate 31 arranged in a spaced manner with the fixing piece, and an adjusting rod 32 arranged between the fixing piece and the induction plate 31. Among them, the induction plate 31 is in direct contact with the paved road surface, and the induction plate 31 and the first screed 22 are always at the same height, so that the actual height of the first screed 22 can be obtained in real time through the induction plate 31, in other words, the actual height of the paved road surface formed by the first screed mechanism 20 can be obtained.

[0046] During the paving process, since the working state of the second screed is relatively stable, the actual height of the paved road surface formed by the paving body 10 is always unchanged, so that the height difference between the paved road surface formed by the first screed mechanism 20 and the paved road surface formed by the paving body 10 can be judged by obtaining the actual height of the first screed 22.

[0047] In an embodiment of the utility model, a controller is arranged in the fixing piece, and the adjusting rod 32 and the induction plate 31 are movably connected, that is, when the actual height of the paved road surface formed by the first screed mechanism 20 changes, the induction plate 31 will also rise or fall accordingly, so as to change the included angle between the induction plate 31 and the adjusting rod 32, and the real-time data brought by the change of the included angle will also be recorded by the controller, so as to help the subsequent step difference adjusting piece (introduced below) to issue appropriate action instructions.

[0048] In the utility model, the controller is structured as a step difference sensor, and the controller can judge the height difference between the paving road surface formed by the paving main body 10 and the paving road surface formed by the first smoothing mechanism 20 by the angle change data between the inductive plate 31 and the adjusting rod 32, thereby being able to accurately and timely send the action instruction to the step difference adjusting piece.

[0049] Preferably, the inductive plate 31 and the adjusting rod 32 form an angle of 20~70°. Preferably, the initial setting value of the inductive plate 31 and the adjusting rod 32 is 45°. Therefore, when the angle between the inductive plate 31 and the adjusting rod 32 is greater than 45°, the first smoothing plate 22 can be adjusted to go up to eliminate the height difference between the first smoothing plate 22 and the second smoothing plate; when the angle between the inductive plate 31 and the adjusting rod 32 is less than 45°, the first smoothing plate 22 can be adjusted to go down to eliminate the height difference between the first smoothing plate 22 and the second smoothing plate.

[0050] In one embodiment, as shown in Figures 3-4 The fixing piece includes a support 301 arranged on the side wall of the smoothing main body 21, and an adapter disc 302 arranged below the support 301. Preferably, the controller is in the adapter disc 302, thereby being able to accurately record the angle change between the inductive plate 31 and the adjusting rod 32.

[0051] In one embodiment, as shown in Figure 3 A support part 303 extending downward along the longitudinal direction is arranged on the support 301. Preferably, the adapter disc 302 is fixed on the support part 303 through a U-shaped screw rod 304 and a butterfly nut 305, thereby improving the firmness and stability between the monitoring mechanism 30 and the smoothing main body 21.

[0052] According to the utility model, the first smoothing mechanism 20 further includes a step difference adjusting piece arranged on the smoothing main body 21. Preferably, the step difference adjusting piece can receive the action instruction sent from the controller, and can control the first smoothing plate 22 according to the action instruction. In other words, the step difference adjusting piece can adjust the height of the first smoothing plate 22 in real time according to the signal sent by the controller, thereby eliminating the height difference between the first smoothing plate 22 and the second smoothing plate.

[0053] In one embodiment, as shown in Figure 2 The step difference adjusting piece includes an adjusting screw rod 41 connected with the first smoothing plate 22, a driving motor 42 arranged in the adjusting screw rod 41, and a conveyor belt 43 sleeved outside the adjusting screw rod 41 and the driving motor 42. Therefore, by forward rotation or reverse rotation of the driving motor 42, the actual height of the first smoothing plate 22 can be adjusted through the conveyor belt 43 and the adjusting screw rod 41, thereby being able to more easily and quickly eliminate the height difference between the first smoothing plate 22 and the second smoothing plate.

[0054] According to the second aspect of the utility model, as Figure 1 Figure 1 As shown in the figure, a paving machine is provided, comprising a road surface height difference adjusting device according to the above, and a second smoothing mechanism 50 arranged on the side of the paving main body 10 away from the first smoothing mechanism 20.

[0055] In the utility model, a vehicle-mounted control system is further arranged in the paving machine, which sets a reference in the initial state, then obtains the included angle change data between the induction plate 31 and the adjusting rod 32 in real time through the controller, compares the height difference between the first smoothing plate 22 and the second smoothing plate (i.e. compares the height difference between the paving road surface formed by the paving main body 10 and the paving road surface formed by the first smoothing mechanism 20), and sends the action instruction to the section difference adjusting piece after analysis and operation by the vehicle-mounted control system;

[0056] Further, the section difference adjusting piece can control the first smoothing plate 22 according to the action instruction after receiving the action instruction from the controller. In other words, the section difference adjusting piece can adjust the height of the first smoothing plate 22 in real time according to the signal from the controller, so as to eliminate the height difference between the first smoothing plate 22 and the second smoothing plate.

[0057] Preferably, the vehicle-mounted control system uploads all data to the cloud server through the DataBox data remote terminal and stores them, and can monitor and check the construction site through the mobile phone APP or the web terminal of the command room.

[0058] According to the third aspect of the utility model, a adjusting method is provided, which utilizes the paving machine according to the above, comprising the following steps:

[0059] Firstly, the controller records the included angle change data between the induction plate 31 and the adjusting rod 32 in real time, so as to judge the height difference between the paving main body 10 and the first smoothing mechanism 20, and then sends the action instruction signal to the section difference adjusting piece.

[0060] Then, the section difference adjusting piece adjusts the height of the first smoothing plate 22 in real time according to the signal from the controller, until the height difference between the first smoothing plate 22 and the second smoothing plate is eliminated.

[0061] Compared with the prior art, the utility model has the advantages of:
