[0002] In some engineering construction, such as roadbed, dam filling and construction site backfilling, soil is often used as building materials. The original structure and state of soil are changed due to excavation, transportation and filling.

[0023] By setting a first electric push rod 27, the first electric push rod 27 is started to drive the base plate 1 to move upward, so that the tamping block 9 is separated from the ground, and the universal wheel 28 is used to drive the tamping block 9 to move to the position to be compacted. The tamping block 9 is lowered and contacted with the ground by adjusting the first electric push rod 27, and the turntable 6 and the fixed column 7 are driven by the driving mechanism 5 to rotate clockwise, so that the fixed column 7 moves while resisting the bottom of the blocking rod 19 and driving the blocking rod 19 to move upward, so that the connecting rod 4 drives the connecting plate 8 and the tamping block 9 to move upward, and the turntable 6 drives the fixed column 7 to rotate until the fixed column 7 is separated from the bottom of the blocking rod 19, and the self-weight of the tamping block 9 is used to move downward and hammer and compact the ground, and the tamping block 9 is repeatedly moved up and down in this way, so as to achieve the effect of local compaction of small venues.

[0024] The driving mechanism 5 includes a support platform 501, a first motor 502, a rotating shaft 1 503, a rotating shaft 2 504, and a transmission belt 505.

By starting the exhaust fan 15 and using the suction nozzle 17 to suck the dust into the conveying pipe 16 and discharge it into the dust collecting box 14, environmental pollution is effectively reduced and the working environment of workers is improved.

[0031] A slide groove 20 is provided on the bottom surface of the base plate 1, and a screw rod 21 is rotatably connected inside the slide groove 20.

A fixed plate 22 is fixedly connected to one side of the base plate 1, and the second motor 23 is fixedly connected to the surface of the fixed plate 22.

[0032] By setting up the second electric push rod 25, while moving to the position to be compacted, the second motor 23 is started to drive the screw rod 21 to rotate, so that the moving block 24 connected to the outer wall thread moves inside the slide groove 20, and the second electric push rod 25 is used to adjust the height of the cleaning brush 26 so that the cleaning brush 26 contacts the ground.

As the turntable 6 drives the fixed column 7 to rotate, until the fixed column 7 is separated from the bottom of the stop rod 19, the tamping block 9 is moved downward by its own weight and hammers and compacts the ground. This is repeated to move the tamping block 9 up and down. The positioning rod 10 passes through the surface of the connecting plate 8, effectively limiting the movement range of the connecting plate 8 and avoiding the misalignment and displacement of the tamping block 9 when it falls. By setting the rubber pad 13, when the tamping block 9 falls, the connecting plate 8 is driven to slide downward on the outer wall of the positioning rod 10, and the bearing block 12 is driven to slide downward on the outer wall of the positioning rod 10, so that the bearing block 12 is in contact with the rubber pad 13, and the elasticity of the damping spring 11 is used to partially buffer the impact of the tamping block 9. During the tamping operation, a large amount of dust will be generated when the tamping block 9 hits the ground, thereby affecting the working environment. By starting the exhaust fan 15, the dust is sucked into the conveying pipe 16 by the suction nozzle 17 and discharged into the collecting The interior of the dust box 14 effectively reduces environmental pollution and improves the working environment of workers. While moving to the position to be compacted, the second motor 23 is started to drive the screw rod 21 to rotate, so that the moving block 24 threadedly connected to the outer wall moves inside the slide groove 20, and the second electric push rod 25 is used to adjust the height of the cleaning brush 26 so that the cleaning brush 26 contacts the ground.
