[0002] In the process of roadbed construction on the joint section of the new and old roads, it is often necessary to use a compaction device to compact the roadbed of the joint section of the new and old roads. At present, the common compaction devices in the prior art are generally divided into cylindrical compaction rollers and cam-type compaction rollers. When processing the new and old roadbeds, it is generally necessary to use a cylindrical compaction roller for primary compaction processing first, and then use a cam-type compaction roller to perform vibration compaction processing on the road surface. Therefore, it is necessary to prepare two different compaction devices to compact the road surface, which makes the construction cost high. Moreover, the raised height of the common cam-type compaction roller is generally fixed, and it is difficult to adjust the vibration amplitude according to the actual situation of the road surface, so it is difficult to apply it to the compaction processing of different roadbeds. In addition, during the use of the cylindrical compaction roller or the cam-type compaction roller, dirt is easily attached to its surface, which is not easy to clean quickly, especially for the cam-type compaction roller, it is even more inconvenient to clean. Therefore, a new roadbed compaction device and compaction method at the joint of the new and old roads are studied to solve the above problems. Summary of the invention

[0025] 2. The roadbed compaction device and compaction method at the joint of the new and old roads drive the petal cam to rotate by linking the bearing member through the rotation of the roller body, so that the petal cam and the second spring drive the slide bar to move up and down, so that the slide bar drives the bracket and the driving shaft to move up and down, and the driving shaft can move laterally through the oblique extrusion connecting piece, so that the connecting piece drives the brush to move laterally through the top plate, so that the brush can clean the roller body, meeting the demand for automatic cleaning;

[0056] A compaction method of a roadbed compaction device at the joint of a new road and an old road, comprising the following steps:
[0057] S1. When compacting the roadbed of the new and old roads during the reconstruction and expansion of the expressway, the mounting plate 1021 is mounted on the walking structure, and the compacting assembly 101 is driven to move by the walking structure, and the motor 1015 drives the first gear 1014 and the second gear 10110 to transmit, the second gear 10110 drives the shaft 2036 bearing 1018 to rotate, and the bearing 1018 drives the roller 1012 and the adjustable rolling assembly 103 to roll, thereby compacting the roadbed area;
[0058] S2. During the rotation of the roller body 1012, the petal cam 202 is also driven to rotate through the outer ring of the bearing member 1018. The convex surface of the petal cam 202 squeezes the roller 2033 to move, so that the roller 2033 drives the second spring 2032 to deform. When the convex surface of the petal cam 202 is separated from the roller 2033, the second spring 2032 drives the roller 2033 to move downward until the petal cam 202 squeezes the roller 2033 again to move, so that the petal cam 202 cooperates with the second spring 2032 to drive the slide bar 2034 to move up and down, so that the slide bar 2034 drives the bracket 2035 and the drive shaft 2036 to move up and down, and the drive shaft 2036 squeezes the connecting piece 205 through the oblique opening 204 to reciprocate horizontally, so that the connecting piece 205 drives the top plate 2012 and the brush 2011 to reciprocate, so that the brush 2011 plays a role in cleaning the roller body 1012.
[0059] S3. When using the cam type compaction operation, remove the rubber plug 1013 and remove the stud 1048 from the fixing groove 1019, then operate the screw 1041 to rotate. The screw 1041 drives the two nuts 1043 to move away from each other, so that the two special-shaped plates 1042 move away from each other, and the special-shaped plates 1042 squeeze the ball 1034 to move. The ball 1034 drives the rolling body 1031 to move. The rolling body 1031 extends out of the roller body 1012 to form a convex surface, thereby impacting the roadbed through the convex surface to achieve the cam type compaction of the roadbed operation.
