Description

Technical Field

[0001] The utility model belongs to the technical field of street lamp base excavation, in particular to a street lamp base excavation device. Background Art

[0002] A street lamp is a device installed on both sides of the road for road lighting. Its main structure includes a lamp pole, a light source installed at the top of the lamp pole, and a bottom buried structure buried in the street lamp base.

[0003] During the streetlight installation process, the most common method currently involves using an excavator bucket mounted on the operating arm of an excavator to automatically perform excavation. However, in practice, manual excavation is often required. This is particularly true when installing streetlights in narrow, building-blocked, or impassable road sections where large machinery (such as excavators) cannot access them. This requires manual excavation.

[0004] Currently, manual excavation uses a drill bucket equipped with an auger to save effort. Specifically, the rotating auger drill penetrates the soil layer, discharging the soil debris to form the streetlight base installation hole. However, during operation, when the auger drill encounters obstacles such as rocks, the auger cannot adjust its angle, making it unable to avoid hard obstacles. Furthermore, since the size of the streetlight base installation hole required for different streetlights varies, the auger bucket and auger blade sizes are mostly fixed, so they can only excavate a fixed roadbed hole of a specific size. Therefore, multiple drillings are required during the excavation process to increase the size of the streetlight base installation hole.

[0005] At the same time, during the excavation process, after the drill bucket is embedded in the soil layer, it is difficult to increase the gap between it and the street lamp base installation hole by shaking the drill bucket, resulting in the drill bucket being squeezed too tightly against the street lamp base installation hole, making it difficult to lift it out of the street lamp base installation hole.

[0042] Example 1

[0043] like Figure 1-5 As shown, a street lamp base excavation device includes an excavation drill bucket mechanism, which includes an excavation drill bucket 1 (excavation drill bucket 1 has a square cross-section, i.e., a rectangular parallelepiped cavity). Similar to existing excavation drill buckets 1, the excavation drill bucket 1 is equipped with an excavation assembly connected thereto, which is used to displace soil within the lamp base.

[0044] Specifically, similar to the existing drill bucket with its own spiral drill cutter, the excavation assembly includes a spiral drill cutter 32 rotatably connected to the excavation drill bucket 1; the top of the excavation drill bucket 1 is fixedly connected to the drive motor 3 (the top of the above-mentioned excavation drill bucket 1 is fixedly connected to the motor cover 31 covering the drive motor 3), and the output shaft of the drive motor 3 is rotatably connected to the top of the excavation drill bucket 1. At the same time, the top of the spiral drill cutter 32 is fixedly connected to the output shaft of the drive motor 3, similar to the existing method.

[0045] During operation, driven by the drive motor 3, the auger cutter 32 continuously drills into the soil layer, while the excavation drill bucket 1 continuously enters the excavated streetlight base installation hole. To facilitate the insertion of the excavation drill bucket 1 into the soil layer, the bottom of the excavation drill bucket 1 is integrally formed with a plurality of tooth-shaped structures 12. The tooth-shaped structures 12 are used to embed the excavation drill bucket 1 into the soil layer.

[0046] A frame-type base 2 is provided at the bottom of the excavation drill bucket 1; at the same time, the street lamp base excavation device also includes a spring adjustment mechanism for adjusting the excavation angle of the excavation drill bucket 1.

[0047] The spring adjustment mechanism is used to realize that when the excavation drill bucket 1 and the spiral drill cutter encounter obstacles during the excavation process, the angles of the excavation drill bucket 1 and the spiral drill cutter can be adjusted by swinging to avoid the obstacles. Secondly, the angles of the excavation drill bucket 1 and the spiral drill cutter can be adjusted by swinging to increase the size of the hole during the excavation process.

[0048] Specifically, the spring adjustment mechanism includes a lifting rod 41 spaced apart on the front and rear sides, and the top of the frame-type base 2 is fixedly connected to an angle adjustment component, the angle adjustment component includes an angle adjustment fixing seat 43, and an adjustment ball 431 is hinged in the angle adjustment fixing seat 43 (specifically, it is the same as the existing method, a hinge groove is opened on the angle adjustment fixing seat 43, and the adjustment ball 431 is limited and hinged in the hinge groove), and the lifting rod 41 is fixedly connected to the adjustment ball 431.

[0049] At the same time, the top of the angle adjustment fixing seat 43 is fixedly connected with an annular spring seat plate 4311, and the adjusting ball 431 passes through the annular spring seat plate 4311; specifically, a circular hole is opened on the annular spring seat plate 4311, and the adjusting ball 431 passes through the circular hole; the adjusting ball 431 is located in the spring cavity of the spring.

[0050] There is a certain gap between the inner wall of the circular hole and the adjusting ball 431, which facilitates the adjusting ball 431 to adjust the angle.

[0051] A spring 42 is sleeved on the above-mentioned lifting rod 41, and the bottom of the spring 42 is fixedly connected to the top of the annular spring seat plate 4311; the upper end of the lifting rod 41 is slidably connected to an upper articulated frame 421, and the top of the spring 42 is fixedly connected to the bottom of the upper articulated frame 421, and the upper articulated frame 421 is hinged to the excavation drill bucket 1.

[0052] Specifically, the upper articulated frame 421 includes a vertical part hinged on the excavation drill bucket 1 (the vertical part is hinged on the excavation drill bucket 1 through a fixed pin shaft 4211), the vertical part is integrally formed with a horizontal part, and the lifting rod 41 is slidably connected to the horizontal part; the top of the spring 42 is fixedly connected to the bottom position of the horizontal part.

[0053] In order to facilitate excavation, T-shaped lifting rods 11 are fixedly connected to the left and right sides of the top of the above-mentioned excavation drill bucket 1.

[0054] During operation, the operator manually lifts the T-shaped lever 11 to press down on the excavation drill bucket 1, while the high-speed rotating auger 32 excavates and drills a hole in the soil. During the excavation and drilling process, the operator continuously raises and lowers the excavation drill bucket 1 and auger 32 using the T-shaped lever 11 to fully dislodge the soil debris. During this raising and lowering process, the spring 42 cooperates with the excavation drill bucket 1 and auger 32 structure to raise and lower it with minimal effort, facilitating excavation.

[0055] At the same time, during the excavation process, by adjusting the excavation drill bucket 1-spiral drill cutter, the excavation direction of the spiral drill cutter 32 is continuously changed during the excavation process. In this way, hard obstacles can be avoided during the excavation process, making it easier to continue excavating.

[0056] At the same time, the hole size can be increased by adjusting the angle in different directions during operation. During this process, the lifting rod 41 continuously adjusts its angle via the articulated ball. As the lifting rod 41 adjusts its angle, the excavation drill bucket 1 and the spiral drill cutter 32 installed therein follow the angle adjustment, thus achieving convenient and flexible excavation.

[0057] Example 2

[0058] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, a slag discharge port 13 is respectively provided at the upper end of the left and right side walls of the excavation drill bucket 1, and an arc-shaped material guide plate 21 is rotatably connected to the slag discharge port 13.

[0059] Specifically, the arc-shaped guide plate 21 includes an arc-shaped portion, and the inner end of the arc-shaped portion is integrally formed with a swivel portion 212 rotatably connected to the excavation drill bucket 1; specifically, the swivel portion 212 is rotatably connected to the circular slag discharge port 13. In this way, when the spiral drill cutter 32 drills the soil layer, the soil debris is carried up and discharged from the slag discharge port 13 to the arc-shaped portion. At this time, the arc-shaped guide plate 21 is rotated to discharge the soil debris.

[0060] The top of the arc-shaped portion is fixedly connected with an arc-shaped handle rod 211, which facilitates the rotation of the arc-shaped material guide plate 21.

[0061] Through the above method, it is convenient to discharge the excavated soil debris to a place slightly away from the street lamp base excavation during the working process, so as to avoid rainwater erosion and filling the street lamp base excavation again.

[0062] Example 3

[0063] like Figure 1-5 As shown, this embodiment builds on the structure of Example 1, with the frame-shaped base 2 being provided with a plurality of hinged interfaces, within which claws A are hingedly connected. Specifically, similar to the existing hinged connection method, claws A are hingedly connected to the hinged interfaces via fixed pins. By rotating claws A until they are embedded in the soil, the entire device can be easily fixed and the excavation position can be easily determined.

[0064] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
