[0002] When the flood control level of the dike of a water conservancy project is improved, it is necessary to carry out up-to-standard construction on the original dike. During the construction of dike embankment addition, first, a connecting ditch is excavated, and the soil excavated from the connecting ditch is piled on the slope. After the connecting ditch is formed, subsequent foundation base treatment construction within the embankment addition range is carried out; since the compaction degree of the original soil does not meet the specification requirements, it is necessary to separately arrange machinery to sun the original soil within the embankment addition range at the toe of the slope. In traditional construction, the excavation of the connecting ditch and the sunning at the toe of the slope are two separate processes. After the connecting ditch is formed, subsequent foundation base treatment construction within the embankment addition range is carried out, which not only causes waste of mechanical resources, increases equipment costs, but also reduces construction efficiency.

[0026] Please refer to Figures 1-5 , the present utility model provides a technical solution: a device for excavating a connected ditch and sunning the foundation base, including an excavator arm 1, a main beam 2, and a bucket 3. The main beam 2 is connected to the excavator arm 1. The bucket 3 is provided with an excavation opening on one side. The excavation opening of the bucket 3 is an inverted trapezoid having the same cross-sectional shape as the cross-section of the connected ditch to be excavated. The bucket 3 is connected to the bottom of the main beam 2. One end of the main beam 2 close to the dike slope is provided with an extension beam 4, and a plurality of plowshares 5 extending downward are arranged on the extension beam 4.

[0027] The excavation opening of the bucket 3 of the present utility model is an inverted trapezoid having the same cross-sectional shape as the cross-section of the connected ditch to be excavated, and a plurality of plowshares 5 extending downward are arranged on the extension beam 4. By moving the bucket 3 and the plowshares 5 through the excavator arm 1, the excavation of the connected ditch and the sunning of the foundation base can be constructed in one forming, which can greatly improve the construction efficiency of the excavation of the connected ditch and the sunning of the foundation base, and at the same time reduce the labor input and the equipment conversion time, bringing higher economic and social benefits to the engineering project.

[0028] Further, the plowshare 5 includes a main shaft 51 and soil-turning plates 52 connected to both sides of the main shaft 51. The main shaft 51 is connected to the extension beam 4 and extends vertically downward. The soil-turning plates 52 are arranged obliquely upward. When the excavator arm 1 moves the plowshare 5, the soil-turning plates 52 arranged obliquely upward guide the soil upward, realizing turning the lower-layer soil to the ground, thereby realizing the sunning of the foundation base soil.

[0029] Specifically, the soil turning plate 52 is arranged at an angle of 150° with the advancing direction of the plowshare 5.

[0030] Furthermore, the main shaft 51 penetrates through the extension beam 4 and is slidably connected to the extension beam 4 in the vertical direction. A plurality of adjustment holes 511 penetrating the main shaft 51 horizontally are arranged at equal intervals from top to bottom on the main shaft 51. A fixing hole 41 penetrating the extension beam 4 horizontally is arranged on the extension beam 4. Any one of the adjustment holes 511 on the main shaft 51 is aligned with the fixing hole 41 and connected by a bolt. During use, the height of the main shaft 51 can be adjusted, and then the corresponding adjustment hole 511 on the main shaft 51 is aligned with the fixing hole 41 and connected by a bolt, so as to realize the height adjustment of the plowshare 5, and thus control the depth of turning and sunning the base soil.

[0031] Furthermore, a connecting rod 6 is connected to the plowshare 5. One connecting rod 6 is commonly connected to the main shafts 51 of a plurality of plowshares 5, so that the heights of a plurality of plowshares 5 can be adjusted at one time, which is convenient for adjustment and can ensure that the heights of a plurality of plowshares 5 are consistent.

[0032] Furthermore, a ridge forming groove 7 is arranged at one end of the main beam 2 away from the dike slope. The ridge forming groove 7 is open on one side, and the opening faces the same direction as the excavation opening of the digging bucket 3. The outer contour of the lower side of the ridge forming groove 7 is the same as the contour required for trimming and forming the surface of the ridge adjacent to the excavated connecting ditch, so that when the connecting ditch is excavated and the base is turned and sunned, the surface of the ridge adjacent to the connecting ditch can be trimmed and formed at the same time.

[0033] Furthermore, the extension beam 4 is connected to the main beam 2 by bolts, and the ridge forming groove 7 is connected to the main beam 2 by bolts, so as to facilitate the disassembly of the extension beam 4, the plowshare 5 on the extension beam 4 and / or the ridge forming groove 7, so that any one or any two functions can be used independently.

[0034] Furthermore, a scraping plate 8 is arranged at the bottom of the digging bucket 3, so as to scrape the bottom of the ditch flat to form a smooth surface.

[0035] Furthermore, a stiffening rib plate 9 is arranged on the side of the main beam 2 facing away from the excavation opening of the digging bucket 3, so as to increase the strength of the main beam 2 and ensure the structural stability.

[0036] It should be noted that, in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
