Description

Technical Field

[0001] This utility model belongs to the field of reservoir box culvert construction technology, specifically relating to a reservoir box culvert foundation excavation equipment. Background Technology

[0002] During the construction of pumped storage reservoirs, box culverts need to be laid. For example, drainage box culverts are laid at the bottom of the reservoir's slag heap. Before laying the box culverts, foundation excavation is required to form trenches. The box culverts are then cast in sections within the trenches and backfilled. The two side walls of the trench form sloping slopes to prevent soil collapse from injuring workers and the box culverts under construction. These slopes also facilitate the entry of workers and building materials into the trenches during the casting process.

[0003] The existing method generally uses an excavator to excavate the trench. The excavator first excavates a trench with a square cross section along the direction of trench movement. Then, it is necessary to excavate the slopes on the two vertical sidewalls of the trench. Because the movement of the excavator bucket is difficult to continuously dig along a slope, it is necessary to make repeated fine adjustments and dig point by point, which results in low efficiency of the excavator when excavating the slope. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed excavation equipment for the construction of reservoir box culvert foundations in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A reservoir box culvert foundation excavation equipment includes a bucket mounted on an excavator arm. Slope excavation devices are detachably connected to the outer walls of both sides of the bucket. Each slope excavation device includes a mounting base detachably connected to the outer wall of the bucket. An adjusting plate is welded to the side of the mounting base away from the bucket. An arc-shaped adjusting hole is formed at the top of the adjusting plate. A scraper is provided on the side of the adjusting plate closest to the excavator. A common pin passes through the bottom end of the scraper and the bottom end of the adjusting plate. The scraper is rotatably connected to the adjusting plate via the pin. A threaded rod is welded to the side wall of the scraper closest to the adjusting plate. The end of the threaded rod away from the scraper passes through the adjusting hole and slides along the length of the adjusting hole. A nut is screwed onto the free end of the threaded rod. A scraper blade is integrally formed on the side of the scraper away from the adjusting plate.

[0007] As a further optimization of this utility model, multiple bucket teeth are detachably connected to the bottom wall of the bucket, and two symmetrically arranged joints are welded to the top of the bucket.

[0008] As a further optimization of this utility model, multiple protruding ribs are provided on both sides of the inner wall of the bucket, and the multiple protruding ribs are equidistantly distributed along the length direction of the inner wall of the bucket.

[0009] As a further optimization of this utility model, connecting holes are provided on both sides of the bucket, and bolts that are rotatably connected to the side walls of the bucket are inserted into the connecting holes. The end of the bolt located outside the bucket is screwed and fixed to the mounting base.

[0010] As a further optimization of this utility model, the inner width of the adjusting hole is greater than the diameter of the threaded rod, and the adjusting hole is concentrically set with the axis of the pin.

[0011] As a further optimization of this utility model, a plurality of semi-cylindrical reinforcing ribs are welded to the side wall of the scraper near the scraper blade, and the reinforcing ribs are evenly distributed along the height direction of the scraper.

[0012] The beneficial effects of this utility model are as follows: In use, the scraper is rotated around the pin to a suitable angle according to the required slope of the excavated slope. Then, the nut is tightened so that the nut presses against the adjusting plate to fix the scraper. After fixing, the user adjusts the position of the slope excavation device so that the side wall of the bucket is in contact with the vertical side wall of the trench. The user then drives the excavator to move along the trench, which drives the scraper installed on the bucket to move. The scraper blade on the scraper can then be used to excavate the soil on the side wall of the slope, forming a slope at a specific angle on the side wall of the trench. This greatly improves the efficiency of slope excavation and makes it convenient for users to use. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a reservoir box culvert foundation construction excavation equipment includes a bucket 1 installed on the excavator arm. Multiple bucket teeth 3 are detachably connected to the bottom wall of the bucket 1. Two symmetrically arranged joints 2 are welded to the top of the bucket 1. The bucket teeth 3 are used to excavate hard geology. The detachable connection method makes it easy to replace the bucket teeth 3 when they wear out after long-term use. The joints 2 facilitate the installation of the bucket 1 on the excavator arm.

[0021] Multiple ribs 4 are provided on both sides of the inner wall of the bucket 1. The multiple ribs 4 are equidistantly distributed along the length of the inner wall of the bucket 1. The ribs 4 are used to form a raised structure on the inner wall of the bucket 1, reducing the adhesion between the soil and the inner wall of the bucket 1, making it easier for the user to pour out the soil excavated from the bucket 1.

[0022] Both sides of the bucket 1 are detachably connected to slope excavation devices. The slope excavation device includes a mounting base 6 that is detachably connected to the outer side wall of the bucket 1. Both sides of the bucket 1 are provided with connection holes 5. Bolts 7 that are rotatably connected to the side wall of the bucket 1 are inserted into the connection holes 5. One end of the bolt 7 located outside the bucket 1 is screwed and fixed to the mounting base 6, so that the mounting base 6 can be detachably connected to the outer side wall of the bucket 1.

[0023] An adjusting plate 8 is welded to the side of the mounting base 6 away from the bucket 1. An adjusting hole 9 with an arc-shaped structure is opened at the top of the adjusting plate 8. A scraper 10 is provided on the side of the adjusting plate 8 close to the excavator. The same pin 11 is passed between the bottom end of the scraper 10 and the bottom end of the adjusting plate 8. The scraper 10 is rotatably connected to the adjusting plate 8 through the pin 11.

[0024] A threaded rod 12 is welded to the side wall of the scraper 10 near the adjusting plate 8. The end of the threaded rod 12 away from the scraper 10 passes through the adjusting plate 8 through the adjusting hole 9 and can slide along the length of the adjusting hole 9. The inner width of the adjusting hole 9 is greater than the diameter of the threaded rod 12, and the adjusting hole 9 is concentric with the axis of the pin 11, so that when the scraper 10 rotates around the pin 11, the threaded rod 12 can slide synchronously in the adjusting hole 9, thereby adjusting the angle of the scraper 10.

[0025] Multiple semi-cylindrical reinforcing ribs 15 are welded to the side wall of the scraper 10 near the scraper 14. The reinforcing ribs 15 are evenly distributed along the height direction of the scraper 10 to improve the overall support performance of the scraper 10 and facilitate the excavation of the trench sidewall.

[0026] A nut 13 is screwed onto the free end of the threaded rod 12, and a scraper 14 for digging the foundation is integrally formed on the side of the scraper 10 away from the adjusting plate 8.

[0027] It should be noted that, in using this reservoir culvert foundation excavation equipment, the bucket 1 is first installed on the excavator arm via the connector 2. The excavator then drives the bucket 1 to excavate a rectangular trench in the foundation. After the trench is excavated, the excavator is moved to one end of the trench. Then, the slope excavation device is installed on the outer wall of the bucket 1 using the mounting base 6 and bolts 7. Simultaneously, the user can rotate the scraper 10 around the pin 11 to adjust the slope according to the desired gradient. Adjust the angle, then tighten the nut 13 towards the adjusting plate 8, so that the nut 13 presses against the adjusting plate 8 to fix the scraper 10. After fixing, the user adjusts the position of the slope excavation device so that the side wall of the bucket 1 is in contact with the vertical side wall of the trench, and drives the excavator to move along the trench, driving the scraper 10 installed on the bucket 1 to move. The scraper blade 14 on the scraper 10 can be used to excavate the soil on the side wall of the slope, and a slope with a specific angle is formed on the side wall of the trench, which greatly improves the efficiency of slope excavation and is convenient for users.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
