Heavy blocks are installed on both sides of the square. The utility model improves the compaction efficiency. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. During use, a hydraulic cylinder is used to drive the compaction plate located under the support platform to move vertically to impact and compact the foundation. During the actual use of the compaction plate, after the bottom surface of the compaction plate repeatedly contacts the surface of the foundation to be compacted, the soil inside the foundation that has not been compacted will adhere to the bottom surface of the compaction plate. During the repeated impact process, the construction workers cannot clean it in time and quickly, which causes the soil on the bottom surface of the compaction plate to be easily thrown up when the compaction plate moves vertically, affecting the safety around the construction site. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0024] Example 1: A compaction device for highway construction, see Figures 1 to 3 A bearing platform 13 is fixedly installed horizontally at the middle end of the inner side of the fixed frame 1, and a hydraulic push cylinder 14 is fixedly installed vertically at the middle end of the top of the bearing platform 13. A tamping block 15 is fixedly installed at the bottom of the piston rod of the hydraulic push cylinder 14 through a coupling, and the tamping block 15 is located below the bearing platform 13. Hollow frames 2 are fixedly installed at the four corners of the inner wall of the fixed frame 1, and a rotating rod 21 is rotatably installed between the sides of each two groups of the hollow frames 2 through a bearing. A fixed sleeve 22 is fixedly sleeved on the middle end surface of each rotating rod 21, and a transmission arc plate 23 is fixedly installed on the outer surface of each fixed sleeve 22. A scraper plate 24 is fixedly installed on the top surface of the side of each transmission arc plate 23, and the top of the scraper plate 24 is movably fitted to the bottom of the tamping block 15. Each rotating rod The outer end surfaces of 21 are movably sleeved with return torsion springs 28, and the return torsion springs 28 are arranged inside the hollow frame 2. Each of the transmission arc plates 23 is hinged with a rotating baffle 25 on one side close to the bottom of the tamping block 15 through a rotating shaft. The scraper plate 24 is movably set on the bottom surface of the tamping block 15 through the rotating rod 21 and the transmission arc plate 23. In combination with the return rotation action of the return torsion spring 28, the scraper plate 24 can move horizontally relative to or towards the bottom surface of the tamping block 15 while the tamping block 15 moves up and down, so that the mud blocks adhered to the bottom surface of the tamping block 15 can be scraped and separated in time and quickly, so as to avoid the adhesion of mud blocks and affect the foundation compaction quality, and prevent the adhered soil from moving arbitrarily under the drive of the tamping block 15 and injuring the personnel on the construction site.

[0025] For details, see Figures 1 to 3 A connecting plate 26 is fixedly installed on one side of the bottom of each rotating baffle 25 close to the scraper plate 24. A limiting bolt 27 is screwed through the middle end of each connecting plate 26 through a thread, and the top of the limiting bolt 27 is screwed to the bottom of the rotating baffle 25 through a thread. The rotating baffle 25 is fixed by the limiting bolt 27 to prevent the rotating baffle 25 from rotating arbitrarily and affecting the collection of the scraped mud by the transmission arc plate 23.

[0026] For further information, see Figures 1 to 3 Water tanks 3 are fixedly installed on both sides of the top of the supporting platform 13. The top of each water tank 3 is hinged with a sealing cover plate 32 through a rotating shaft. The structure of the water tank 3 can store dust reduction water for convenient use.

[0027] It is worth noting that see Figures 1 to 3 Each of the water storage tanks 3 is fixedly connected to a connecting elbow 31 at the bottom of the side, and a control valve 33 is fixedly installed on the outside of each connecting elbow 31. A water collecting pipe 34 is fixedly installed longitudinally at the bottom of the support platform 13, and the bottom of the connecting elbow 31 and the top of the water collecting pipe 34 are fixedly connected. Through the connection between the connecting elbow 31 and the water collecting pipe 34, the dust suppression water can be transported and processed.

[0028] It is worth noting that see Figures 1 to 3 The bottom of each water collecting pipe 34 is fixedly connected to a spray nozzle 35, and the number of the spray nozzles 35 is several groups. Through the structural function of the spray nozzles 35, the dust reduction water can be evenly sprayed on the outside of the compaction block 15, so as to prevent the dust generated by compaction from affecting the air quality of the construction site and blocking the real-time observation of the construction personnel.

[0029] It is worth mentioning that see Figures 1 to 3 The four corner surfaces of the bottom of the fixed frame 1 are vertically fixed with support rods 11, and the bottom of each support rod 11 is fixed with a self-locking universal wheel 12. The structural function of the self-locking universal wheel 12 can assist the movement of the fixed frame 1 and the tamping block 15.

[0030] During operation, the fixed frame 1 is pushed to move on the construction site under the drive of the self-locking universal wheel 12, and the compacting block 15 is moved to the top of the foundation to be compacted. Then, the hydraulic push cylinder 14 is started to drive the compacting block 15 to descend and impact the foundation so that it can be compacted. As the compacting block 15 descends, it causes the scraper plate 24 to move against it, so that the two sets of scraper plates 24 can move horizontally at the bottom of the compacting block 15 synchronously and relatively to the surface of the compacting block 15. The mud blocks are scraped off and collected on the top surface of the transmission arc plate 23, and then the transmission arc plate 23 is provided with corresponding driving force, so that the transmission arc plate 23 can drive the rotating rod 21 to rotate synchronously inside the hollow frame 2, and the return torsion spring 28 sleeved on the outside of the rotating rod 21 is pushed to deform it. Then, when the bottom of the tamping block 15 touches the ground, the transmission arc plate 23 and the scraper plate 24 rotate and are located on the two side walls of the outside of the tamping block 15. Then, when the tamping block 15 is driven and lifted, After the transmission arc plate 23 and the scraper plate 24 move synchronously to the edge of the bottom surface of the tamping block 15, under the restoring driving force of the reset torsion spring 28, the rotating rod 21 can be driven to restore and rotate synchronously, thereby driving the transmission plate and the scraper plate 24 to rotate synchronously and fit to the bottom surface of the tamping block 15 again. As the tamping block 15 is lifted vertically, the scraper plate 24 moves horizontally toward the bottom surface of the tamping block 15, and the bottom surface of the tamping block 15 is scraped and cleaned again, and the surface of the transmission arc plate 23 is When a large amount of mud is accumulated, the limit bolt 27 is screwed to remove it from the connecting plate 26 and the transmission arc plate 23, and then the rotating baffle 25 is pulled to open it from the surface of the transmission arc plate 23, and then the mud accumulated on the surface of the transmission arc plate 23 is cleaned. While compacting the foundation, the control valve 33 is opened, and the dust reduction water inside the water storage tank 3 is transported to the inside of the water collecting pipe 34 through the connecting elbow 31, and then combined with the spray nozzle 35 to spray the outside of the compaction block 15 for dust reduction treatment.
