Description

Technical Field

[0001] This utility model relates to the field of river excavation technology, and in particular to a river foundation excavation device. Background Technology

[0002] Riverbed excavation equipment refers to specialized machines used in river management, dredging, and excavation projects for digging, dredging, or extracting materials from the riverbed. These mainly include excavators, dredgers, and other specialized equipment.

[0003] When existing excavators dig mud from the bottom of riverbeds, excess soil remains in the bucket's movement path. The bucket itself cannot effectively scrape away this soil, requiring repeated scraping to clean up the remaining soil. This makes the construction process time-consuming and labor-intensive, increasing manpower and energy consumption. Therefore, there is a need for a riverbed foundation excavation device that can scrape away the soil debris while digging the bottom mud, saving time and labor. Utility Model Content

[0004] The purpose of this utility model is to provide a riverbed foundation excavation device to solve the problem mentioned in the background art, where when the bucket of an existing excavator digs the soil at the bottom of the river, excess soil remains on the movement trajectory of the bucket. The bucket itself cannot effectively scrape off this soil, and it is necessary to scrape repeatedly to clean up the residual soil, which makes the construction process time-consuming and labor-intensive, and increases the consumption of manpower and energy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a riverbed foundation excavation device, comprising: The digging assembly includes a boom, a telescopic rod, a bucket, and a fixed base. The fixed base is fixed to the excavator. One end of the boom is rotatably connected to the fixed base. The telescopic rod is distributed on the fixed base and the boom, and both ends are rotatably connected to the fixed base and the boom, respectively. The bucket is rotatably connected to the other end of the boom. The soil scraping assembly includes a support shaft, a torsion spring, a connecting ring, a connecting rod, and a connecting plate. There are two support shafts, which are fixed on both sides of the bucket respectively. The connecting ring is sleeved on the support shaft. The torsion spring is sleeved on the support shaft, with one end fixed to the side of the bucket and the other end fixed to the side of the connecting ring. The connecting rod is fixed on the connecting ring, and the connecting plate is fixed on the connecting rod.

[0006] Furthermore, the scraper assembly also includes a limiting disc, which is fixed to the other end of the support shaft away from the bucket. The same torsion spring is sleeved on the support shaft between the connecting ring and the limiting disc, and the two ends of the torsion spring are respectively fixed to the connecting ring and the limiting disc.

[0007] Furthermore, the digging assembly also includes a connecting rod, one end of which is rotatably connected to the end of the boom near the bucket, and the other end is rotatably connected to the bucket.

[0008] Furthermore, it also includes a connecting assembly, which includes a slot, a threaded hole, a locking screw, and a insert plate. The slot is located on the side of the connecting rod, the threaded hole is located on the side of the slot, the locking screw is screwed into the threaded hole, and the insert plate is fixed to both ends of the connecting plate and inserted into the slot.

[0009] Furthermore, the connecting assembly also includes a spring post, one end of which is fixed to the side of the bucket and close to the support shaft.

[0010] Furthermore, the connecting plate is movably connected to the outside of the bucket, and one end of the locking screw is pressed against the insert plate.

[0011] Compared with existing technologies, the advantages of this utility model are: This invention utilizes a scraping assembly. The excavator controls the telescopic rod, which moves the boom and, consequently, the bucket to excavate the mud at the bottom of the riverbed. As the bucket digs the mud, the lower end of the connecting plate adheres to the mud. As the bucket moves the connecting plate, the connecting rod at the other end rotates around the support shaft. Under the action of a torsion spring, the lower end of the connecting plate scrapes away the loose soil left by the bucket. This design achieves integrated "digging-scraping" operation, avoiding secondary cleaning, reducing manual intervention and repetitive operations, and significantly reducing time costs and energy waste.

[0012] Based on the aforementioned beneficial effects, the designed connecting assembly allows for easy replacement of the connecting plate after a period of use when the connecting plate becomes severely worn. The locking screw in the threaded hole can be loosened, the connecting plate pulled, and the insert plate moved out of the slot, allowing for replacement with a new connecting plate. Alternatively, when the excavator is not in use, the locking screw can be loosened, the connecting plate pulled, and the connecting plate moved along the slot. When the insert plate moves from the innermost end of the slot to the outermost end, the locking screw can be tightened, and the connecting plate pulled closer to the bucket. The movable end of the spring column is then pressed down. When the connecting rod moves past the spring column, the movable end of the spring column is released, preventing the connecting rod from rotating in the opposite direction. This design allows for quick replacement of the connecting plate after wear, reducing maintenance costs. Furthermore, the connecting plate unfolds to scrape soil during operation and retracts near the bucket when idle, avoiding space occupation. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-4 As shown, this embodiment is a riverbed foundation excavation device, including: The digging assembly includes a boom 10, a telescopic boom 11, a bucket 13, and a fixed base 14. The fixed base 14 is fixed on the excavator. One end of the boom 10 is rotatably connected to the fixed base 14. The telescopic boom 11 is distributed on the fixed base 14 and the boom 10, and both ends are rotatably connected to the fixed base 14 and the boom 10, respectively. The bucket 13 is rotatably connected to the other end of the boom 10. The digging assembly also includes a connecting rod 12, one end of which is rotatably connected to the end of the boom 10 near the bucket 13, and the other end is rotatably connected to the bucket 13. The boom 10 serves as a connector, the telescopic rod 11 is used to control the rotation of the boom 10 and the bucket 13. The movement of the movable end of the telescopic rod 11 is controlled by the hydraulic control system on the excavator, thereby controlling the movement of the boom 10 and the bucket 13. The connecting rod 12 serves as a connector, the bucket 13 is used for digging, and the fixed seat 14 serves as a support.

[0020] The soil scraping assembly includes a support shaft 20, a torsion spring 22, a connecting ring 23, a connecting rod 24, and a connecting plate 25. There are two support shafts 20, which are fixed on both sides of the bucket 13 respectively. The connecting ring 23 is sleeved on the support shaft 20. The torsion spring 22 is sleeved on the support shaft 20, with one end fixed to the side of the bucket 13 and the other end fixed to the side of the connecting ring 23. The connecting rod 24 is fixed on the connecting ring 23, and the connecting plate 25 is fixed on the connecting rod 24. The soil scraping assembly also includes a limiting plate 21, which is fixed to the other end of the support shaft 20 away from the bucket 13. The same torsion spring 22 is sleeved on the support shaft 20 between the connecting ring 23 and the limiting plate 21, and the two ends of the torsion spring 22 are fixed to the connecting ring 23 and the limiting plate 21 respectively. The support shaft 20 provides support and facilitates the rotation of the connecting ring 23. The limiting plate 21 provides a limiting function, the torsion spring 22 provides a resetting function, the connecting ring 23 and the connecting rod 24 provide a connection function, and the connecting plate 25 is used for scraping soil.

[0021] Working principle: The excavator controls the telescopic boom 11, which drives the boom 10 to move, and then drives the bucket 13 to move, excavating the mud at the bottom of the river. When the bucket 13 digs the mud, it causes the lower end of the connecting plate 25 to stick to the mud. As the bucket 13 drives the connecting plate 25 to move, the connecting ring 23 at the other end of the connecting rod 24 rotates around the support shaft 20. Under the action of the torsion spring 22, the lower end of the connecting plate 25 can scrape away the broken soil left by the bucket 13, realizing the integrated "digging-scraping" operation, avoiding secondary cleaning, reducing manual intervention and repetitive operations, and significantly reducing time costs and energy waste.

[0022] Please see Figure 2-4 As shown, this embodiment is based on the above embodiment 1, with the addition of a connecting component. The connecting component includes a slot 30, a threaded hole 31, a locking screw 32, and an insert plate 33. The slot 30 is opened on the side of the connecting rod 24, the threaded hole 31 is opened on the side of the slot 30, the locking screw 32 is screwed into the threaded hole 31, and the insert plate 33 is fixed to both ends of the connecting plate 25 and inserted into the slot 30. The connecting assembly also includes a spring post 34, one end of which is fixed to the side of the bucket 13 and close to the support shaft 20; The connecting plate 25 is movably connected to the outside of the bucket 13, and one end of the locking screw 32 is pressed against the insert plate 33; The slot 30 and the insert plate 33 serve as a connection, the threaded hole 31 and the locking screw 32 are used to fix the insert plate 33, and the spring post 34 serves as a limit.

[0023] Working principle: After a period of use, when the connecting plate 25 is severely worn, the locking screw 32 in the threaded hole 31 can be loosened, and the connecting plate 25 can be pulled to move the insert plate 33 out of the slot 30, allowing a new connecting plate 25 to be replaced. Alternatively, when the excavator is not in use, the locking screw 32 can be loosened, and the connecting plate 25 can be pulled to move along the slot 30. When the insert plate 33 is at the innermost end of the slot 30 and moves to the outer end of the slot 30, the locking screw 32 can be tightened. Then, the connecting plate 25 can be pulled closer to the bucket 13, and the movable end of the spring column 34 can be pressed. When the connecting rod 24 moves past the spring column 34, the movable end of the spring column 34 can be released. At this time, the connecting rod 24 cannot rotate in the opposite direction. This allows for quick replacement of the connecting plate 25 after wear, reducing maintenance costs. In addition, the connecting plate 25 can be extended to scrape soil during operation and can be retracted to the vicinity of the bucket 13 when idle, avoiding space occupation.
