Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an excavator slope compaction and finishing structure. Background Art

[0002] During the excavation of the roadbed slope, the excavator uses a bucket to cut and trim the slope from bottom to top. When the excavator is used for excavation and trimming, the slope is usually compacted by the excavator operator by re-shooting the excavator bucket. At the same time, the slope trimming is also achieved by the excavator operator by translating the excavator bucket. However, the size of the bucket itself is limited, and when the bucket is used to compact the slope, the compaction degree varies depending on the height of the bucket. The operation surface of direct compaction with the bucket is small and inefficient. At the same time, the technical level of the excavator operator is relatively high, and there are certain safety hazards. Therefore, designing a device that can both trim and compact the slope has important research significance in the field of roadbed slope excavation construction.

[0003] The Chinese patent document discloses "a roadbed slope compactor", and its publication number is CN215948141U. The patent uses a rotating seat, a rotating block, a first hydraulic cylinder, a connecting arm and a sliding sleeve in combination, so that the first hydraulic cylinder adjusts the use height of the road roller through the connecting arm, and the second hydraulic cylinder adjusts the use position of the road roller through the sliding sleeve, so that the device can compact slopes of various heights, improves the applicability of the device, and facilitates the operation of construction personnel. However, it is necessary to introduce a professional compactor with a complex structure at the construction site. Most construction sites have rugged terrain and can only accommodate one necessary excavator. Multiple construction equipment increases the construction cost. Utility Model Content
