[0023] As a technical optimization solution of the utility model, Figure 1 and Figure 2 As shown, the cross-section of the end of the connecting frame 306 is L-shaped, the cross-section of the support frame 1 is U-shaped, the multiple connecting rods 303 are parallel to each other, and the lines connecting the four rotation points of two connecting rods 303 in the same group form a parallelogram, so when the four connecting rods 303 rotate at the same time, the mounting plate 304 can move.

[0024] As a technical optimization solution of the utility model, Figure 1 , Figure 3 and Figure 4 As shown, the support frame 1 is rotatably connected with a connecting plate 4, and a connecting structure 5 is provided on the connecting plate 4. The connecting structure 5 includes a connecting block 501 and a connecting frame 502. The connecting plate 4 is fixedly connected with a connecting block 501, and a connecting frame 502 is rotatably connected to the connecting block 501. The connecting frame 502 is rotatably connected with a connecting block 503, and the connecting block 503 is engaged with the connecting plate 504. The connecting plate 504 is provided with a plurality of mounting holes 505. The cross-section of the end of the connecting plate 504 is an L-shaped structure, and a positioning structure is provided on the connecting plate 504. 6. The locking structure 6 includes a guide sleeve 601 and a sliding column 602. Two guide sleeves 601 are fixedly connected to the connecting plate 504. The guide sleeve 601 is slidably connected to the sliding column 602. The top ends of the two sliding columns 602 are fixedly connected to the same pulling plate 604. The bottom end of the pulling plate 604 is fixedly connected to an insert block 606. The bottom end of the insert block 606 is engaged with the connecting block 503. The connecting block 501 is perpendicular to the connecting plate 4. The cross-section of one end of the connecting block 503 is T-shaped, so that the traction device and the leveling device can be quickly separated.

[0025] As a technical optimization solution of the utility model, Figure 3 As shown, the outer sleeve of the sliding column 602 is provided with a return spring 603, one end of the return spring 603 abuts against the sliding column 602, and the other end of the return spring 603 abuts against the guide sleeve 601, so that the insertion block 606 and the connecting block 503 can be more tightly engaged.

[0026] As a technical optimization solution of the utility model, Figure 3 As shown, the pull plate 604 is rotatably connected to a rotating block 605, and the cross-section of the bottom end of the sliding column 602 is a T-shaped structure. Therefore, the pull plate 604 can be supported by the rotating block 605 to avoid the need to hold the pull plate 604 all the time during the disassembly process, thereby effectively improving the convenience of operation.

[0027] When the utility model is in use, the connecting plate 504 is first installed on the traction device through the multiple mounting holes 505 with the bolts, and then the connecting block 503 and the connecting plate 504 are engaged. When the connecting block 503 and the connecting plate 504 are fully engaged, the plug block 606 will be engaged with the connecting block 503 under the action of the return spring 603. At this time, the connecting block 503 and the connecting plate 504 cannot be separated, thereby realizing the rapid connection between the leveling device and the traction device. When the road surface needs to be leveled, it can be controlled by the electric The push rod 301 extends, and the extension of the electric push rod 301 will drive the connecting shaft 302 to move. When the connecting shaft 302 moves, the four connecting rods 303 will rotate at the same time. When the four connecting rods 303 rotate at the same time, the mounting plate 304 will move. The movement of the mounting plate 304 will drive the push plate 305 to move toward the ground, so that the push plate 305 contacts the ground. Then the traction device can be controlled to move. The movement of the traction device will cause the two moving wheels 2 to roll on the ground, and the support frame 1 and the mounting plate 304 will move synchronously. The plate 305 will move with the mounting plate 304. The push plate 305 will level the road surface during the movement. In the process of the movement of the mounting plate 304, the pressure roller 307 will be driven to roll on the ground through the connecting frame 306, so that the leveled soil can be compacted, so that the overall stability of the leveled soil is better, thereby effectively improving the leveling effect. When it is necessary to separate the leveling device and the traction device, the pull plate 604 can be pulled. The movement of the pull plate 604 will cause the sliding column 602 to slide inside the guide sleeve 601 When the pull plate 604 moves, the reset spring 603 contracts, thereby guiding the movement of the pull plate 604. The movement of the pull plate 604 will drive the insertion block 606 to move. When the insertion block 606 is separated from the connecting block 503, the rotating block 605 can be rotated to support the pull plate 604. At this time, the reset spring 603 cannot extend to drive the insertion block 606 to engage with the connecting block 503 again, and then the connecting block 503 and the connecting plate 504 can be separated. At this time, the leveling device can be quickly disassembled, which is more convenient to use.
