Description

Technical Field

[0001] The invention relates to a tamping machine capable of adjusting the tamping area, and belongs to the technical field of mechanical manufacturing. Background Art

[0002] A tamping machine is a machine that needs to fully compact the foundation soil in order to reduce the gaps between soil particles, increase its density, ensure the stability of the foundation, and obtain sufficient bearing capacity. It is widely used in building construction and road construction. Existing tamping machines can already achieve good foundation compaction effects. However, the tamping area is fixed during the use of the tamping machine, and the tamping area of ​​the tamping machine cannot be flexibly adjusted according to needs. Although some tamping machines have achieved flexible adjustment of the tamping area, they cannot ensure consistent counterweights during the tamping process, and the uniformity of the tamping is poor. For example, publication number (CN112663591A) discloses a tamping machine for civil engineering, comprising a protective shell, an L-shaped fixing plate welded to one side of the interior of the protective shell, a tamping drive motor fixed to the bottom of the L-shaped fixing plate, and a first active bevel gear fixed to the output end of the tamping drive motor. The present invention achieves a good effect of tamping by the mutual cooperation among the protective housing, the tamping drive motor, the active spur gear, the driven spur gear and the tamping mechanism. When the device moves forward, the ground is gradually tamped by the two tamping mechanisms, so that untamped ground is avoided when the device moves forward, and the tamping effect is improved. The mutual cooperation among the protective housing, the handrail, the roller and the mobile drive motor enables the device to move forward in a rolling manner. Although this technical solution avoids the situation where the device tips over and the situation where workers are injured due to unstable support, and eliminates the safety hazards in the use of the device, when this technical solution is used for tamping, the tamping area is fixed and the use is not flexible enough.

[0003] Another example is the publication number (CN211113589U), which discloses a ramming machine with adjustable ramming area, including a ramming machine bottom plate, a threaded rod, an armrest, a motor and an eccentric block, wherein a sliding hole is arranged on one side of the ramming machine bottom plate, a sliding groove is arranged on the bottom of the ramming machine bottom plate, a telescopic bottom plate is installed on one side of the ramming machine bottom plate, a telescopic rod is arranged on one side of the telescopic bottom plate, the telescopic rod is embedded in the sliding hole, a connecting plate is arranged on one side of the telescopic rod, the connecting plate is embedded in the sliding groove, and the second pulley and the eccentric block are fixed to each other. The telescopic rod is fixed with sliding rods on both sides, and a rotating torque is provided at one end of the threaded rod. A pressure plate is fixed on one side of the bottom plate of the rammer. Although this technical solution can adjust the area of ​​the rammer and the ground, the contact area between the rammer and the bottom surface is large at the beginning, and the ramming depth is small. The device will not float up and down greatly due to excessive ramming of the soil, which is inconvenient to operate. However, when this technical solution adjusts the ramming area, the weights of the bottom plate and the pressure plate are different, which will lead to poor uniformity of soil compaction during the ramming process, and there are certain disadvantages in the use process.

[0004] In view of this, an optimized and improved tamping machine with adjustable tamping area is proposed. Summary of the invention
