Description

Technical Field

[0001] This application relates to the field of dredging technology, and more specifically, to a trench dredging device for municipal engineering. Background Technology

[0002] Municipal engineering encompasses various municipal infrastructure construction projects, such as common urban roads, underground pipelines, sewage treatment, and garbage disposal. It also includes the post-construction maintenance of such infrastructure projects. For example, municipal ditches often accumulate large amounts of garbage, which can affect the effective drainage of the ditches and cause foul odors. Regular cleaning using appropriate cleaning devices is necessary to maintain unobstructed flow and ensure a good sanitary environment in the city.

[0003] A search revealed a public announcement (CN114892752A) for a trench dredging device used in municipal engineering construction. The device includes a cleaning box and a mobile base. A dredging shovel is movably installed at the front end of the cleaning box. The bottom of the mobile base is equipped with wheels, and a support chassis is provided between the mobile base and the cleaning box. During use, because the cleaning box is a fixed, integrated structure, long-term contact with garbage can cause the secretions from the garbage to corrode and damage the inner wall of the bottom of the cleaning box, thus affecting the overall performance of the device.

[0004] To address the aforementioned problems, this application provides a trench dredging device for municipal engineering. Utility Model Content

[0005] The dredging device for municipal engineering provided in this application adopts the following technical solution:

[0006] A dredging device for municipal engineering includes a base, and an auxiliary mechanism is provided on the top of the base;

[0007] The auxiliary mechanism includes a housing located on top of the base. Mounting slots are provided on both the front and rear sides of the housing, with two mounting slots symmetrically arranged about the centerline of the housing. Sealing strips are fixedly connected to the top and bottom of each mounting slot. A sloped plate is embedded between the four sealing strips. A connecting plate is fixedly connected to the front side of the sloped plate, with a groove on its top. A support plate is fixedly connected to the front side of the housing, located at the bottom of the connecting plate. A drain pipe is fixedly connected to the bottom of the housing. A nylon mesh conveyor belt is provided on one side of the sloped plate, with two rollers embedded inside. The rear ends of both rollers extend to the rear side of the housing. Connecting components are provided on the outer side of the nylon mesh conveyor belt.

[0008] Furthermore, the connecting component includes a motor, which is fixedly connected to the top of the housing. The output shaft of the motor is fixedly connected to a threaded rod, the bottom end of which extends into the housing. The connection between the threaded rod and the housing is movably connected via a bearing.

[0009] The above technical solution allows the threaded rod to move the pressing plate up and down in the later stages.

[0010] Furthermore, a movable groove is provided on the top of the box body, and a threaded plate and a movable plate are threadedly sleeved on the outer wall of the threaded rod. The threaded plate and the movable plate are fixedly connected, and the threaded plate is located on top of the movable plate. A baffle is fixedly connected to one side of the threaded plate, and the top of the baffle extends into the movable groove.

[0011] The above technical solution allows for flexible adjustment of the baffle height and also enables the limiting of the threaded plate and the movable plate by opening the movable groove.

[0012] Furthermore, two springs and a telescopic rod are fixedly connected to the bottom of the movable plate. The two springs are located on both sides of the telescopic rod, and a pressing plate is fixedly connected to the bottom end of the telescopic rod and the two springs. The pressing plate is located at the top of the nylon mesh conveyor belt.

[0013] By using the above technical solution and setting two springs, the pressing plate can be made to fit more tightly against the nylon mesh conveyor belt.

[0014] Furthermore, a sealing plate is movably embedded inside one side of the box, with the front end of the sealing plate extending to the front side of the box. Two fixing plates are fixedly connected to the other side of the box, and a roller is movably embedded between the two fixing plates. A second motor is fixedly connected to the rear side of the rear fixing plate, and the output shaft of the second motor is fixedly connected to the rear end of the roller. A sludge removal shovel is fixedly connected to the outer side of the roller.

[0015] The above technical solution, by setting two fixing plates, can support the motor and the roller.

[0016] Furthermore, two connecting blocks and two telescopic frames are fixedly connected to the bottom of the box, and movable rods are movably embedded between the two connecting blocks and the two telescopic frames.

[0017] The above technical solution, by setting two telescopic frames, makes it easy for users to adjust the tilt angle of the box later.

[0018] Furthermore, a support rod is fixedly sleeved on the outer side of the movable rod on the left, and an electric hydraulic push rod is fixedly sleeved on the outer side of the movable rod on the right. The bottom ends of both the support rod and the electric hydraulic push rod are fixedly connected to the base.

[0019] By employing the above technical solution and incorporating an electro-hydraulic push rod, the device can achieve better performance.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] Hold the connecting plate and pull the slope plate forward to detach it from the box. Since sealing strips are fixedly embedded in both mounting slots, the internal space of the device can be sealed. At the same time, the support plate on the front of the box allows the staff to place the slope plate on top of the support plate when installing it, thereby supporting the slope plate and making it convenient for the staff to clean and replace the slope plate, thus ensuring the performance of the slope plate.

[0022] By using a nylon mesh conveyor belt and connecting components, the waste can be efficiently separated into dry and wet parts. The discharge of wastewater itself reduces the weight of the waste, making the device lighter and more spacious. The process of moving and cleaning becomes easier and easier, thus facilitating flexible use by municipal personnel. Attached Figure Description

[0031] This application discloses a trench dredging device for municipal engineering. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 It includes a base 1, and an auxiliary mechanism is provided on the top of the base 1;

[0032] The auxiliary mechanism includes a housing 2, which is located on top of the base 1. The housing 2 has mounting slots on both the front and rear sides. The two mounting slots are symmetrically arranged about the center line of the housing 2. The top and bottom of the two mounting slots are fixedly connected to sealing strips 3. A slope plate 4 is embedded between the four sealing strips 3. A connecting plate 5 is fixedly connected to the front side of the slope plate 4. The top of the connecting plate 5 has a groove. A support plate 6 is fixedly connected to the front side of the housing 2. The support plate 6 is located at the bottom of the connecting plate 5. A drain pipe 7 is fixedly connected to the bottom of the housing 2. A nylon mesh conveyor belt 8 is provided on one side of the slope plate 4. Two rollers 9 are embedded inside the nylon mesh conveyor belt 8. The rear ends of the two rollers 9 extend to the rear side of the housing 2.

[0033] Please see Figure 1 and Figure 2The outer side of the nylon mesh conveyor belt 8 is provided with a connecting component, which includes a motor 10. The motor 10 is fixedly connected to the top of the box 2. The output shaft of the motor 10 is fixedly connected to a threaded rod 11. The bottom end of the threaded rod 11 extends into the inside of the box 2. The connection between the threaded rod 11 and the box 2 is movably connected by a bearing. A movable groove is opened on the top of the box 2. A threaded plate 12 and a movable plate 13 are threadedly sleeved on the outer wall of the threaded rod 11. The threaded plate 12 and the movable plate 13 are fixedly connected. The threaded plate 12 is located on top of the movable plate 13. A baffle 14 is fixedly connected to one side of the threaded plate 12. The top of the baffle 14 extends into the movable groove. By opening the movable groove, the threaded rod 11 can flexibly adjust the height of the baffle 14 and limit the threaded plate 12 and the movable plate 13, so that the baffle 14 and the pressing plate 17 can maintain the vertical direction when moving up and down.

[0034] Please see Figure 1 and Figure 2 Two springs 15 and a telescopic rod 16 are fixedly connected to the bottom of the movable plate 13. The two springs 15 are located on both sides of the telescopic rod 16. A pressing plate 17 is fixedly connected to the bottom of the telescopic rod 16 and the two springs 15. The pressing plate 17 is located on the top of the nylon mesh conveyor belt 8. A sealing plate 18 is movably embedded inside one side of the box body 2. The front end of the sealing plate 18 extends to the front side of the box body 2. Two fixing plates 19 are fixedly connected to the other side of the box body 2. A roller 20 is movably embedded between the two fixing plates 19. A motor 21 is fixedly connected to the rear side of the rear fixing plate 19. The output shaft of the motor 21 is fixedly connected to the rear end of the roller 20. A sludge removal shovel 22 is fixedly connected to the outside of the roller 20. By setting two springs 15, the pressing plate 17 can be more tightly attached to the nylon mesh conveyor belt 8.

[0035] Please see Figure 1 The bottom of the box 2 is fixedly connected to two connecting blocks 23 and two telescopic frames 24. Movable rods 25 are movably embedded between the two connecting blocks 23 and the two telescopic frames 24. A support rod 26 is fixedly sleeved on the outside of the left movable rod 25, and an electric hydraulic push rod 27 is fixedly sleeved on the outside of the right movable rod 25. The bottom ends of the support rod 26 and the electric hydraulic push rod 27 are fixedly connected to the base 1. Through the cooperation of the two telescopic frames 24, the two connecting blocks 23, the support rod 26 and the electric hydraulic push rod 27, it is convenient for the user to adjust the tilt angle of the box 2 later.

[0036] The implementation principle of this embodiment is as follows: When using the device, it can first be pushed to the designated position via the base 1, and then the garbage inside the ditch can be cleaned by the shovel 22. The motor 10 and motor 21 are started, so that the output shaft of motor 10 drives the threaded rod 11 to rotate. Because the baffle 14 matches the moving groove, the threaded plate 12 can drive the baffle 14 to move upward. The moving plate 13 drives the pressing plate 17 to move upward via two springs 15 and the telescopic rod 16. At the same time, the output shaft of motor 21 drives the roller 20 to rotate. The roller 20 drives the front shovel 22 to rotate, pouring the garbage into the top of the nylon mesh conveyor belt 8 inside the box 2. Then, the motor 10 and the motor 21 rotate in opposite directions, so that the baffle 14 and the front shovel 22 return to their original positions. When the baffle 14 moves downward, it will press the garbage on the top of the nylon mesh conveyor belt 8, so that the water inside the garbage will pass through the nylon mesh conveyor belt 8 and be discharged from the box 2 through the drain pipe 7. Then, the nylon mesh conveyor belt 8 is started again to transport the garbage with the water removed from its top to the top of the slope plate 4.

[0037] Then the staff pulls the sealing plate 18 forward and removes it from the inside of the container 2. They then activate the electric hydraulic push rod 27, which lifts one side of the container 2 through the right support rod 26 and the telescopic frame 24. Since the two support rods 26 are movably connected to the two connecting blocks 23 and the two telescopic frames 24, the tilt angle of the container 2 can be flexibly adjusted. After the container 2 tilts, the garbage on top of the slope plate 4 will slide to one side of the container 2 due to gravity. At the same time, since the slope plate 4 is sloping, the garbage can slide down faster.

[0038] After all operations are completed, hold the connecting plate 5 and place your fingers in the groove position to pull the slope plate 4 forward, so that the slope plate 4 is separated from the box 2. Since the sealing strips 3 are fixedly embedded in both mounting grooves, the sealing of the internal space of the device can be guaranteed. At the same time, the support plate 6 provided on the front side of the box 2 allows the staff to place the slope plate 4 on the top of the support plate 6 when installing it, so as to support the slope plate 4 and facilitate the staff to clean and replace the slope plate 4, thereby ensuring the performance of the slope plate 4.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
