[0030] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In this embodiment, an earthwork compaction device and a method of use are disclosed. Figure 1 The whole structure of the earth compacting device is shown. Figure 2 The top view of the hammer assembly in the earthwork compaction device is shown; Figure 3 The invention shows the structure of the connection between the hammer rod and the hammer assembly in the earth compacting device.

[0032] Please refer to Figures 1 to 4 The earthwork compaction device of the present invention comprises: Figure 1As shown, the present invention provides an earth compaction device, including: an engineering vehicle 1, a swing arm 2 arranged on one side of the engineering vehicle 1, a breaker hammer 3 arranged at the lower end of the swing arm 2, a hammer rod 4 arranged at the lower end of the breaker hammer 3, and a hammer assembly 5 arranged at the lower end of the hammer rod 4; wherein the breaker hammer 3 is used to drive the hammer assembly 5 to move up and down; the hammer assembly 5 is used to compact the earth. Specifically, the bottom earth compaction device and use method provided by the present invention, in this embodiment, the engineering vehicle 1 is an excavator, and the breaker hammer 3 is arranged to drive the hammer assembly 5 to move up and down, and the impact force of the breaker hammer 3 is used to drive the hammer assembly 5 to reciprocate, so as to realize repeated rolling of the earth, thereby achieving the effect of fast, efficient and high-quality compaction of the bottom base earth. In addition, the device can also flexibly adjust the shape of the hammer assembly 5 according to the specific conditions of the construction site, so that it can adapt to different geological conditions and terrain environments.

[0033] like Figure 2 and Figure 3 As shown, further, the hammer assembly 5 includes a hammer plate 51, a sleeve 52 arranged above the hammer plate 51, and a wing plate 53 arranged around the sleeve 52; wherein the hammer rod 4 is sleeved in the sleeve 52; and the wing plate 53 is used to reinforce the sleeve 52. Specifically, the sleeve 52 connects the hammer plate 51 and the hammer rod. The wing plate 53 is used to enhance the overall strength and rigidity of the sleeve 52, to prevent the sleeve 52 from shaking or tilting under the drive of the hammer rod 4, and also to play a supporting role, so that it can withstand a larger load without breaking or other damage. And the shape and size of the hammer plate can be selected according to the construction needs. In this embodiment, the hammer plate 51 is square, and in other embodiments, the hammer plate 51 can be made into a round or oval shape. And after the construction is completed, the hammer assembly 5 can be disassembled and the hammer assembly 5 can be recycled, and the disassembly of the hammer assembly 5 is convenient for the storage and transportation of the hammer assembly, which reduces the cost.

[0034] Furthermore, the thickness of the hammer plate 51 is 25 to 35 mm. Specifically, considering factors such as the wear resistance and service life of the hammer plate 51, controlling the thickness between 25 and 35 mm can effectively prevent the hammer plate 51 from being deformed or even broken due to excessive pressure, thereby ensuring sufficient strength and toughness without being too heavy to cause inconvenience in operation.

[0035] Furthermore, the hammer plate 51 is a steel plate. Specifically, the hammer plate 51 uses steel as the basic material based on the good balance between strength, plasticity and cost-effectiveness of steel materials, so that the hammer plate 51 can be processed and formed and is not easily deformed. The steel plate can not only significantly improve the impact resistance of the hammer plate while maintaining sufficient toughness, reduce deformation caused by long-term operation, but also effectively extend the service life of the equipment.

[0036] Furthermore, a rib plate is provided on the hammer plate 51, and the rib plate is used to increase the strength of the hammer plate 51. Specifically, the number, shape and distribution position of the rib plates can be flexibly determined according to actual conditions, as long as the strength of the hammer plate 51 can be effectively increased. For example, in the area where the force of the hammer plate 51 is most concentrated, such as the center, increasing the density and thickness of the rib plates can effectively disperse the impact force and prevent damage caused by local stress concentration.

[0037] Furthermore, the upper end of the hammer rod 4 is vertically arranged at the bottom of the breaker 3, and the lower end is vertically arranged at the top of the hammer plate 51. Specifically, the function of the hammer rod 4 is to connect the breaker 3 and the hammer plate 51 so that the two form a complete system. By adjusting the length and angle of the hammer rod 4, the center of gravity of the entire system can be located at a suitable position, thereby ensuring its stability.

[0038] Furthermore, the outer diameter of the hammer rod 4 is smaller than the inner diameter of the sleeve 52. Specifically, the hammer rod 4 is inserted into the sleeve 52, and is used in an interference fit and socket-type manner with the hammer rod 4. In order to better connect the hammer rod 4 and the sleeve 52, the inner diameter of the sleeve 52 is slightly larger than the diameter of the hammer rod 4 by about 2 to 3 mm, so that the sleeve 52 will not easily fall from the hammer rod 4. In a specific embodiment, the lower end of the hammer rod 4 is set as a sphere, and a protrusion is provided inside the sleeve 52 for clamping the sphere. The sphere is inserted into the sleeve 52, and the sphere is locked by the protrusion to fix the hammer rod 4 in the sleeve 52.

[0039] Furthermore, a buffer is provided in the sleeve 52. Specifically, the buffer absorbs part of the energy when the hammer plate 51 moves downward, reduces the impact force on the earth below, reduces noise and vibration, and can also extend the service life of the hammer plate 51.

[0040] Furthermore, the buffer is a rubber asbestos board. Specifically, the rubber asbestos board is a commonly used buffer material with good elasticity, durability and corrosion resistance. When actually used, the inner wall of the sleeve 52 can be stuffed with a 3 mm rubber asbestos board.

[0041] Corresponding to the above device, the present invention also provides an earthwork compaction method, Figure 4 The flowchart of the soil compaction method according to an embodiment of the present invention is shown.

[0042] like Figure 4 As shown, the present invention also provides a method for compacting soil using the above method, which specifically includes the following steps:

[0043] S1: Move the engineering vehicle to the designated location, and use the swing arm to drive the hammer assembly to the location where the earthwork is to be compacted;

[0044] S2: driving the hammer assembly to repeatedly hammer the earth by swinging the swing arm up and down;

[0045] S3: After the current soil is compacted, the swing arm drives the hammer assembly to the next piece of soil to be compacted, and repeats step S2 until the compaction of all target soils is completed.

[0046] To sum up, the earth compaction device and the use method thereof provided by the present invention are operated by workers on two engineering vehicles 1, and a breaker hammer 3 is installed on the engineering vehicle 1 to serve as a power source rammer, in conjunction with a hammer plate 51. When in use, the engineering vehicle 1 works simultaneously on both sides of the earth, and compacts the earth in layers, effectively ensuring the compaction quality, effectively improving the construction quality and efficiency of the earthwork project, and improving work efficiency and economic benefits.
