A second transmission wheel 12 is arranged at the middle position of the outside of the first rotating shaft 13, and a second transmission belt 11 is arranged between the second transmission wheel 12 and the outside of the flywheel 24. When the first rotating shaft 13 rotates, the second transmission wheel 12 can be driven to rotate, thereby driving the flywheel 24 and the eccentric block 25 to rotate through the second transmission belt 11. The centrifugal force generated when the eccentric block 25 rotates drives the swing frame 8 and the tamping plate 9 to vibrate up and down to tamp the foundation;

[0021] As a further implementation of this embodiment, Figure 1-4 As shown, a protective cover shell 10 is provided at the top of the outer side of the swing frame 8, and mounting ear plates 18 are provided at both ends of the protective cover shell 10.

A limiting block 29 is arranged in the telescopic sleeve 15 at the top of the stabilizing guide rod 17. The top of the telescopic sleeve 15 is fixedly connected to the bottom of the handle 14. The telescopic sleeve 15 is limited to the outside of the stabilizing guide rod 17 by the limiting block 29, thereby effectively reducing the vibration felt by the worker when holding the handle 14 to control the rammer, reducing the discomfort brought to the operator by the rammer, making the operation more convenient and the operation time more durable, and the feasibility is strong;

[0024] When a worker holds the handle 14 to control the rammer, the damping spring 28 reduces the vibration of the rammer body transmitted to the handle 14 through the frame 2, making it more comfortable to hold and control the rammer. As the damping spring 28 is stretched and compressed, the telescopic sleeve 15 is lifted and slid on the stabilizing guide rod 17 to support and stabilize the damping spring 28.

[0025] Specific working principle:

[0026] When using a frog-type rammer to compact the foundation of a photovoltaic power station, first, before using the rammer, the protective cover shell 10 is positioned and sleeved and installed on the outside of the flywheel 24 and the eccentric block 25 on the swing frame 8, and then the first mounting bolt 19 is installed into the inside of the second fixing screw hole 22 and the second mounting bolt 20 is installed into the inside of the first fixing screw hole 21, so that the protective cover shell 10 is firmly installed on the outside of the flywheel 24 and the eccentric block 25 on the swing frame 8. When tamping starts, the operator controls the start-up drive motor 3 through the controller 16 to drive the first transmission wheel 4 to rotate, which can drive the driven wheel 7 to rotate through the first transmission belt 5, thereby driving the first rotating shaft 13 to rotate, and when the first rotating shaft 13 rotates, it can drive the second transmission wheel 12 to rotate, thereby The flywheel 24 and the eccentric mass 25 are driven to rotate by the second transmission belt 11. The centrifugal force generated when the eccentric mass 25 rotates drives the swing frame 8 and the tamping plate 9 to vibrate up and down to compact the foundation. At the same time, the flywheel 24 and the eccentric mass 25 are covered by the protective cover shell 10 for isolation and safety protection to prevent workers from accidentally entering the tamping range and being injured by the rotating eccentric mass 25. At the same time, the vibration of the tamping machine body transmitted to the handle 14 through the frame 2 is reduced by the damping spring 28, making it more comfortable to hold and operate the tamping machine. In addition, as the damping spring 28 is stretched and compressed under force, the telescopic sleeve 15 is lifted and slid on the stabilizing guide rod 17 to support and stabilize the damping spring 28, thereby making it easier for workers to operate the tamping machine to compact the foundation of the photovoltaic power station.
