[0021] Furthermore, the vibratory compactor model 3 is the hydraulic vibratory compactor VC120S. This is an existing technology that is purchased externally, so it will not be described in detail. The vibratory compactor is controlled by the excavator's hydraulic system.
[0022] Furthermore, the air pump 2-5-2 model is a 5.5KW vortex air pump. This is an existing technology that is purchased externally, so it will not be described in detail. It is powered by the excavator's electrical system.
[0023] Working principle:
[0024] In use, the mounting bracket 2-2 is detachably fixed to the excavator boom. The vibratory compactor 3 is then placed against the surface to be compacted via the excavator boom. The vibratory compactor 3 performs the compaction operation. The raised edge 1-2 helps to block dust and prevent its spread. Powering on the air pump 2-5-2 creates negative pressure inside the dust collection box 2-5-1, drawing the dust generated by the vibratory compactor 3 through the collection hood 1-5. The dust then moves along the hose 2-5-4 into the dust collection box 2-5-1. After the dust is filtered out by the dust collector bag 2-5-3, the gas is discharged through the air pump 2-5-2. The above method can effectively deal with the dust generated by the vibratory compactor 3, ensuring the operator's visibility and purifying the construction environment. The dust collector bag 2-5-3 can be disassembled and cleaned regularly to ensure the dust removal effect. The vibration generated by the vibratory compactor 3 during operation is longitudinal. The vibration is transmitted to the sliding column 1-3 through the outer shell 1-1, causing the sliding column 1-3 to slide up and down along the sliding plate 2-1. At the same time, the spring 1-4 is continuously compressed and reset, which can cancel the vibration and prevent the vibration from being transmitted to the excavator, causing the excavator parts to loosen or be damaged. The spring 1-4 is a helical spring.
[0025] Remove the positioning bolt 2-6 and push the sliding plate 2-1 to drive the fixed frame 2-2 to rotate along the connecting base 2-4. The angle of the sliding plate 2-1 can be adjusted, which in turn can adjust the angle of the vibratory compactor 3. After adjusting the angle, insert the positioning bolt 2-6 to reset it and fix the angle. The above method can be used to perform the compaction operation on the slope.
[0026] When deep ground compaction is required, the fixing plate 4-1 is placed against the bottom surface of the vibrating plate of the vibratory compactor 3, and then the pressure plate 4-3 is pressed onto the top surface of the vibrating plate and fixed with nuts, thus completing the fixing of the fixing plate 4-1. The length of the sleeve 4-5 can be adjusted by sliding it along the extension rod 4-4, and adjusted according to the required compaction depth. After adjusting the length, it is fixed with the set screw. During operation, the extension rod 4-4 and the sleeve 4-5 are inserted into the ground surface. The vibration of the vibratory compactor 3 is transmitted to the extension rod 4-4 and the sleeve 4-5 through the vibrating plate and the fixing plate 4-1, thus compacting deep ground. At the same time, the fixing plate 4-1 can compact the ground surface, realizing combined operation and increasing the compaction speed.
[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
