Compared with manual tamping or a small rammer, the area compacted at one time is larger and the compaction speed is faster.

[0007] Preferably, the connection and adjustment mechanism includes a fixed bracket, a transmission rod, and a second driving member installed on both sides of the equipment platform, and the fixed bracket is rotatably connected to the transmission rod; a connecting rod 1 is provided at the connection between the transmission rod and the second driving member, and two connecting plates are provided on the fixed bracket, and a connecting groove for inserting the driving member is formed between the two connecting plates, and a connecting rod 2 is provided in the connecting groove, and the two ends of the second driving member are rotatably connected to the connecting rod 1 and the connecting rod 2 respectively; a rolling roller is rotatably connected between the ends of the two transmission rods away from the second driving member.

[0009] Preferably, a plurality of synchronization rods are arranged between the two transmission rods.

[0010] By adopting the above technical solution, the synchronization rod can ensure that the transmission rods on both sides can rotate synchronously, avoiding installation errors caused by asynchronous movement of the transmission rods on both sides and improving installation efficiency.

At the same time, since the annular protrusion is inserted in the positioning groove and a soft rubber pad is installed on the annular protrusion, the sealing ability is improved, so that the lubricating oil is not easy to flow out. Therefore, a lubricating groove is arranged on the annular protrusion. When the rolling roller rotates in the working state, each rotation will align the lubricating groove with the positioning groove once. At this time, the lubricating oil in the lubricating oil groove can flow out through the lubricating groove, so as to realize automatic lubrication of the rolling roller and the transmission rod during the working process and reduce the friction loss between the rolling roller and the transmission rod in a dusty environment. An oil inlet is arranged on the outer side of the transmission rod and communicated with the lubricating oil groove, so as to facilitate the replenishment of lubricating oil into the lubricating oil groove. At the same time, a sealing groove is installed on the oil inlet to prevent the lubricating oil from flowing out of the oil inlet.

[0023] Preferably, the lubrication groove of the annular protrusion is provided with a mounting chamfer.

[0024] By adopting the above technical solution, an installation chamfer is set at the lubrication groove, which makes it easier for the lubrication groove to be turned into the positioning groove each time, thereby avoiding small errors caused by vibrations generated during the working process that may damage the positioning groove and the annular protrusion.
