[0002] Engineering machinery is an important part of the equipment industry. Generally speaking, all mechanical equipment required for earthwork construction, road construction and maintenance, mobile lifting and loading and unloading operations, and comprehensive mechanized construction projects required for various construction projects are called engineering machinery. Compactors are used in engineering construction. The working parts of the compactor are the hammer head and hammer rod, and the purpose is compaction. The working parts of the compactor are the hammer head and hammer rod. There is a pair of working groove wheels driven by the transmission system, which can clamp the hammer rod, lift the hammer head to a certain height, and then release the hammer rod to make the hammer head fall freely to complete the compaction operation. Therefore, long-term use of the compactor may cause the compaction head to be damaged and need to be replaced. Therefore, in the process of replacing the compaction head, screw fixing can be used. Screw fixing is both stable and quick to disassemble.

[0003] In the Chinese authorized patent announcement number CN211898309U, a tamping device for an automatic tamping machine includes a tamping part, a frame, and a tamping machine body.

However, the tamping head used for drilling holes in the commonly used tamping machine will inevitably be damaged during use, and the tamping head also needs to be disassembled when holes of different sizes need to be drilled. When the tamping head of the tamping machine is disassembled, the disassembly process is relatively complicated and the disassembly is slow, which will affect the subsequent use efficiency of the device. Therefore, it is necessary to propose a tamping machine whose tamping head can be quickly replaced. Summary of the invention

A limiting groove 5 is provided on one side of the surface of the second connecting piece 4, and an electric lifter 6 is movably connected to the inner wall of the limiting groove 5. Through the setting of the limiting groove 5, the electric lifter 6 can be inserted into the limiting groove 5 for limiting when the device does not need to rotate, so as to prevent the electric turntable 3 from shifting due to inertia when descending due to the excessive weight of the tamping head 20;

[0023] A tamping machine 7 is arranged at the upper end of the toothed belt wheel 1, a connecting rod 8 is connected to one side of the tamping machine 7, a first electric telescopic rod 9 is connected to the other side of the tamping machine 7, a fixing screw 10 is passed through one side of the outer wall of the first electric telescopic rod 9, and a connecting rod 8 is connected to one end of the outer wall of the fixing screw 10, and the setting of the first electric telescopic rod 9 can assist in adjusting the angle of the connecting rod 8;

[0024] A bracket 11 is provided at one end of the connecting rod 8, and an electric slide rail 12 is provided on one side of the outer wall of the bracket 11. A slider 13 is movably connected to the outer wall of the electric slide rail 12. The electric slide rail 12 can assist the bracket 11 to rise, and when it rises to a certain position, it plays a role of assisting the descent when the tamping head 20 needs to fall freely.

[0025] A counterweight 17 is connected to the lower end of the bracket 11, and a fixing plate 18 is fixedly installed at the lower end of the counterweight 17. A through screw 19 is passed through one side of the outer wall of the fixing plate 18, and one end of the through screw 19 is connected to a tamping head 20. The upper end of the outer wall of the connecting rod 8 is connected to a connecting plate 14, and a rotating shaft 15 is provided on one side of the outer wall of the connecting plate 14. One end of the outer wall of the rotating shaft 15 is connected to a second electric telescopic rod 16.

[0026] Working principle: first, the compactor 7 is moved to the specified position through the toothed belt wheel 1, and then the compactor head 20 is installed through the screw 19 and the fixing plate 18 and the counterweight 17, so that it is convenient to remove the compactor head 20, and then the compactor 7 is started when in use, so that when the compactor 7 is working, the switch of the first electric telescopic rod 9 is turned on, so that the first electric telescopic rod 9 is driven by the fixing screw 10 and the connecting rod 8 to move up and down, and it plays an auxiliary role for the second electric telescopic rod 16, so that the switch of the second electric telescopic rod 16 is turned on, so that the second electric telescopic rod 16 can be moved up and down. The telescopic rod 16 drives the bracket 11 and the tamping head 20 installed at the bottom of the bracket 11 to rise. Therefore, the coordinated use of the first electric telescopic rod 9 and the second electric telescopic rod 16 can make the tamping machine 7 drive the tamping head 20 to rise. When it rises to a certain height, the switches of the first electric telescopic rod 9 and the second electric telescopic rod 16 are turned off, so that the bracket 11 drives the tamping head 20 to fall freely. When the first electric telescopic rod 9 and the second electric telescopic rod 16 are in operation, the switch of the electric slide rail 12 is turned on, so that the electric slide rail 12 drives the slider 13 to slide between the connecting rod 8 , thereby assisting the first electric telescopic rod 9 and the second electric telescopic rod 16 to perform the ascending operation. After the first electric telescopic rod 9 and the second electric telescopic rod 16 are closed, the weight of the tamping head 20 can drive the slider 13 to slide downward on the outer wall of the electric slide rail 12, thereby facilitating the weight of the tamping head 20 in free fall, so as to work. When the tamping machine 7 needs to be adjusted to work at an angle, the overall power supply of the tamping machine 7 is first turned off, and then the switch of the electric turntable 3 is turned on, so that the electric turntable 3 drives the tamping machine 7 as a whole to rotate and adjust the angle. When it is adjusted to a certain angle, When the electric lift 6 reaches the limit value, the switch of the electric lift 6 is turned on to make the electric lift 6 rise and insert it into the limit groove 5 to fix the electric turntable 3, and then the switch of the electric turntable 3 is turned off to make the limit fixing effect of the electric turntable 3 better to prevent the electric turntable 3 from rotating due to inertia caused by the tamping machine 7 being too heavy. The model of the electric lift 6 is: YS-NZ100-12A, the model of the first electric telescopic rod 9 and the second electric telescopic rod 16 are: XYDHA24-800, the model of the electric slide rail 12 is: PXC175, and the model of the electric turntable 3 is: wp401.
