Description

Technical Field

[0001] This application relates to the field of road construction technology, specifically to a rapid excavation bucket for street light foundations. Background Technology

[0002] Streetlights are generally installed in the median strip between motor vehicle and non-motor vehicle lanes. The width of the median strip is narrow and fixed, so the construction space for excavating the streetlight foundation is relatively compact, requiring continuous operation with the help of small excavators. However, the bucket of the small excavator is a traditional spoon-shaped bucket, which can only be used for slope excavation. The disadvantages of slope excavation in the median strip are that it has many drawbacks: (1) The outward expansion area of ​​slope excavation is larger and more irregular, while the streetlight foundation only requires a rectangular space. The extra space excavated needs to be backfilled, which increases the construction steps; (2) Slope excavation increases the risk of damage to the curb. If corresponding measures are provided to protect the curb, it will add extra steps; (3) For soft soil foundations, it is necessary to ensure the compaction of the soil in the foundation pit during excavation and to ensure that the foundation pit will not sink after excavation. Therefore, the traditional excavation method has shortcomings in many aspects such as tools, steps, and results. Summary of the Invention

[0003] This application provides a rapid excavation bucket for street light foundations, which reduces the additional steps required by traditional buckets, eliminates the risk of curb damage, and improves the excavation quality of the foundation pit.

[0004] The technical solution of this application is as follows:

[0005] A rapid excavation bucket for street light foundations includes a bucket having a top surface, a front surface, and two side surfaces, the top surface, front surface, and two side surfaces forming a rectangular body with an open bottom and rear.

[0006] The lower ends of the front and sides are both serrated;

[0007] The top surface is provided with a connecting mechanism for connecting the excavator boom. The connecting mechanism is surrounded by several circular holes, and a screw is provided in the circular holes. Each screw passes downward through the top surface and is fixedly connected to a steel plate below the top surface.

[0008] The screw is fitted with a nut, and the inner diameter of the nut is larger than the diameter of the circular hole.

[0009] Furthermore, the connecting mechanism is located at the center of the top surface.

[0010] Furthermore, the number of circular holes is four and they are located at the four corners of the rectangle, with the rectangle centered on the connecting mechanism.

[0011] Furthermore, the connecting mechanism includes an arched block and a through hole penetrating the arched block, wherein a matching pin is provided in the through hole.

[0012] Furthermore, the thickness of the steel plate ranges from 3cm to 5cm.

[0013] Furthermore, the inner surfaces of the front and side surfaces are sandblasted.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this application are as follows:

[0015] 1. This application connects the bucket to the excavator's boom. The boom presses the soil vertically downwards, compacting the soil and forcing the soil inside the rectangular structure against the inner wall. During the pressing process, the nut remains tightened at the lower end of the screw, and the steel plate adheres to the inner surface of the top. After pressing, the nut is loosened upwards, and workers hammer the upper end of the screw, using the steel plate to compact the soil inside the rectangle. After compaction, the boom is lifted vertically, forming a basically complete street light foundation. At this point, the foundation pit is rectangular, with any loose soil remaining inside, which workers can remove. This application achieves one-time foundation forming during excavation, without expanding the excavation area, and also creates a relatively flat and solid foundation pit bottom.

[0016] 2. This application uses a vertical lifting method, which eliminates the risk of touching the curbstone and can prevent damage to the curbstone during construction. Attached Figure Description

[0022] Based on the background technology described above, please refer to the appendix. Figure 1 and attached Figure 2This application provides a rapid excavation bucket for street light foundations, including a bucket with a top surface 1, a front surface 2, and two side surfaces 3. The top surface 1, front surface 2, and two side surfaces 3 form a rectangular body with an open bottom and rear. The lower ends of the front surface 2 and side surfaces 3 are serrated. The top surface 1 is provided with a connecting mechanism 4 for connecting to the excavator arm. The connecting mechanism 4 is surrounded by several circular holes 5. Each circular hole 5 contains a screw 6. Each screw 6 passes downward through the top surface 1 and is fixedly connected to a steel plate 7 below the top surface 1. Each screw 6 is fitted with a nut 8, and the inner diameter of the nut 8 is larger than the diameter of the circular hole 5.

[0023] When in use, connect the connecting mechanism 4 to the boom of the excavator, turn the top surface 1 towards the front, and form a digging space on the rear side, and then dig according to the marked position.

[0024] In this application, the serrated lower end significantly improves the bucket's embedding ability, preventing bucket deformation caused by hard contact. During use, the bucket is connected to the excavator's boom, which presses the soil vertically downwards. This pressing process compacts the soil and forces the soil inside the rectangular body against the inner wall. During pressing, the nut 8 remains tightened at the lower end of the screw rod 6, and the steel plate 7 adheres to the inner surface of the top surface 1. After pressing, the nut 8 is loosened upwards, and the worker hammers the upper end of the screw rod 6, using the steel plate 7 to compact the soil inside the rectangular body. After compaction, the boom is lifted vertically, forming a basically complete streetlight foundation. At this point, the pit is rectangular, with possible loose soil remaining inside, which can be excavated by the worker. This application achieves one-time foundation forming during excavation, without expanding the excavation area, and also creates a relatively flat pit bottom.

[0025] This application is particularly suitable for soft soil foundations, where the soil is compacted and then lifted. During the lifting process, there is no need to worry about whether the bottom of the lifted soil will adhere to the soil below, because the purpose of this technical solution is to form a foundation pit, and excess soil can be removed. Moreover, during the hammering of the screw rod 6, the shaking of the bucket will also be transmitted to the soil, causing fractures at weak points.

[0026] In a preferred embodiment of this application, the connecting mechanism 4 is located at the center of the top surface 1. Positioning the connecting mechanism 4 at the center helps with pit positioning and ensures uniform stress on the steel plate 7, thereby improving the flatness of the pit bottom.

[0027] In one specific embodiment of the above implementation, there are four circular holes 5 located at the four corners of a rectangle, with the connecting mechanism as the center. The rectangle is located on the top surface 1, and the spacing between the circular holes 5 is the side length of the rectangle. In a specific implementation, the side length of the rectangle can be designed to be half the side length of the top surface 1.

[0028] In a preferred embodiment of the above embodiments, the connecting mechanism 4 includes an arched block and a through hole 9 penetrating the arched block, with a matching pin 10 disposed within the through hole 9. The pin 10 connects to the excavator's boom, preserving rotational freedom and providing greater flexibility for actual construction.

[0029] In a preferred embodiment of this application, the thickness of the steel plate 7 ranges from 3cm to 5cm. The steel plate 7 should not be too thin, as a thinner steel plate 7 will result in insufficient compaction and is prone to deformation during hammering.

[0030] In a preferred embodiment of this application, the inner surfaces of the front 2 and side 3 are sandblasted. Sandblasting enhances the adhesion of the inner surfaces, which helps to lift the soil. Where not described in this application, existing technologies can be used or referenced.

[0031] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
