Description

Technical Field

[0001] This application relates to the field of waterway management equipment technology, and in particular to a dredging device for waterway improvement projects. Background Technology

[0002] Currently, during river channel improvement construction, dredgers are usually used to remove silt from the riverbed. Transport vehicles are arranged on the bank in advance. After the dredgers remove the silt, it is transferred to the transport vehicles, which then transport the silt to the treatment plant for drying or landfilling.

[0003] An existing patent (publication number: CN221297800U) discloses an engineering equipment for waterway dredging projects. The equipment includes a transfer chamber with a discharge port at its bottom; a conveyor chain with its starting end located below the transfer chamber; multiple pallets distributed along the length of the conveyor chain; each pallet has two guard plates positioned on either side of the pallet along the width of the conveyor chain; the guard plates abut against the side walls of the transfer chamber. This waterway dredging equipment can be applied to dredging and treatment projects of various sizes in rivers and waterways, offering advantages such as wide applicability, high reliability, low operating costs, and high transportation efficiency, thus solving the problem of spillage and pollution during silt transportation.

[0004] However, it was found in the above scheme that when transporting silt, the scheme uses multiple sets of pallets and conveyor chains for transfer. However, in use, due to the gaps between the pallets, silt and water can easily drip into the gaps, which can easily cause secondary pollution to the environment around the waterway. Utility Model Content

[0005] The purpose of this application is to provide a dredging device for waterway improvement projects, which has the advantages of improving the sealing performance during sludge transportation, reducing the risk of sludge leakage, and ensuring continuous and stable transportation process through the uninterrupted operation of the conveyor belt, thereby increasing the amount of sludge processed per unit time and improving transportation efficiency, thus solving the problems mentioned in the background art.

[0006] This application provides a dredging device for waterway improvement projects, employing the following technical solution: It includes a base plate, on which two support plates are fixedly mounted. A reduction motor is fixedly mounted on the front of one of the support plates. Two connecting rods and two synchronous belts are located above the base plate. The output shaft of the reduction motor is fixedly connected to the end of the corresponding connecting rod. The outer surface of each connecting rod is rotatably connected to the inner wall of the corresponding support plate. Two pulleys are fixedly connected to the outer surface of each connecting rod, and each pulley meshes with the corresponding synchronous belt. A support platform is fixedly mounted between the two support plates. The outer surface of each connecting rod is rotatably connected to the inner wall of the support platform. A conveyor belt is located above the base plate. The outer surface of each synchronous belt is riveted to the inner wall of the conveyor belt. An installation strip is fixedly connected to the side of each support plate that is close to each other. A first sealing strip is fixedly mounted on the bottom surface of each installation strip. Two second sealing strips are fixedly mounted on the outer surface of the support platform. Each first and second sealing strip is in contact with the conveyor belt.

[0007] By adopting the above technical solution, a support plate is installed on the upper surface of the base plate to fix the support plate. A reduction motor is set on the front of one of the support plates. The connecting rod and synchronous belt are set above the base plate. The output shaft of the reduction motor is fixed to the end of the left connecting rod, so that the reduction motor can drive the connecting rod to rotate. The connecting rod is connected to the inner wall of the support plate in a rotatable connection, so that the support plate can limit the movement of the connecting rod. A pulley is installed on the outer surface of the connecting rod and meshes with the synchronous belt, so that when the connecting rod rotates, it can drive the pulley to rotate. Through the connection between the pulley and the synchronous belt, when the reduction motor drives the connecting rod to rotate, the two synchronous belts can operate synchronously. The conveyor belt is set above the base plate. The conveyor belt and the corresponding synchronous belt are fixed together by riveting, so that the synchronous belt can drive the conveyor belt when it is in operation. An installation strip is installed on the side of the support plate that is close to each other, and a first sealing strip is installed on the inner wall of the installation strip. A second sealing strip is set on the outer surface of the support platform. Since the inner wall of the conveyor belt is in contact with the second sealing strip and the outer surface of the conveyor belt is in contact with the first sealing strip, the edges of the conveyor belt can be sealed by the first and second sealing strips when the conveyor belt is transporting sludge. This device can improve the sealing performance when transporting sludge, reduce the risk of sludge leakage, and ensure that the conveyor belt operates continuously and stably, thereby increasing the amount of sludge processed per unit time and improving transportation efficiency.

[0008] Preferably, the upper and lower surfaces of the support platform are fixedly connected with bearing plates, and the side of each bearing plate that is far away from each other is in sliding contact with the inner wall of the conveyor belt.

[0009] By adopting the above technical solution, the bearing plate is installed on the upper and lower surfaces of the support platform and set as a fixed connection. The bearing plate is in contact with the conveyor belt, so that the bearing plate can support the conveyor belt. The support platform is slightly lower than the bearing plate, so that the synchronous belt can fit in contact with the surface of the support platform, thereby achieving support for the synchronous belt and the conveyor belt.

[0010] Preferably, a support frame is fixedly installed on the bottom surface of the base plate, and a transfer compartment is provided above the base plate. Limiting frames are fixedly connected to both the front and back of the transfer compartment.

[0011] By adopting the above technical solution, the support frame is installed on the bottom surface of the base plate to support the base plate and the upper components. The transfer chamber is set above the base plate, and the limiting frame is installed on the front and back of the transfer chamber. The transfer chamber can hold silt, and the limiting frame can support the transfer chamber.

[0012] Preferably, the bottom surface of the transfer chamber is fixedly connected to a discharge pipe, and a valve is fixedly installed on the outer surface of the discharge pipe.

[0013] By adopting the above technical solution, the discharge pipe is installed on the bottom of the transfer chamber, and a valve is installed on the outer surface of the discharge pipe. Through the cooperation of the discharge pipe and the valve, the sludge inside the transfer chamber can be easily discharged.

[0014] Preferably, a mounting base is fixedly connected to the right side of the support frame, and a limiting shell is fixedly connected to the upper surface of the mounting base.

[0015] By adopting the above technical solution, the mounting base is installed on the right side of the support frame, and the limiting shell is installed on the upper surface of the mounting base to achieve support for the limiting shell.

[0016] Preferably, a sliding plate is slidably connected to the inner wall of the limiting shell, and a scraper is fixedly connected to the upper surface of the sliding plate.

[0017] By adopting the above technical solution, the slide plate is installed on the inner wall of the limiting shell and set as a sliding connection to limit the slide plate. The scraper is installed on the upper surface of the slide plate and set as a fixed connection, so that the slide plate and the scraper can rise and fall together. The top part of the scraper contacts the bottom surface of the conveyor belt, so that when the conveyor belt rotates, the scraper can remove the attached sludge.

[0018] Preferably, a guide bucket is fixedly connected to the right side of the scraper.

[0019] By adopting the above technical solution, the guide bucket is set on the right side of the scraper to achieve the positioning of the guide bucket. After the sludge is scraped off, the guide bucket can guide the sludge to the right side for discharge.

[0020] Preferably, the inner bottom wall of the limiting shell is fixedly connected with guide rods and springs arranged at equal intervals, the outer surface of each guide rod is slidably connected to the inner wall of the slide plate, and the top end of each spring is fixedly connected to the bottom surface of the slide plate.

[0021] By adopting the above technical solution, a guide rod and a spring are set on the inner bottom wall of the limiting shell, and the outer surface of the guide rod is connected to the slide plate to form a sliding connection, which improves the stability of the slide plate when it is raised and lowered. The top of the spring is fixed to the bottom surface of the slide plate so that the spring can always press against the slide plate and ensure that the scraper is always in contact with the bottom surface of the conveyor belt.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This dredging device for waterway improvement projects comprises pulleys, synchronous belts, a first sealing strip, and a second sealing strip. A geared motor drives a connecting rod to rotate, which in turn rotates the pulleys. The engagement of the pulleys with the synchronous belts allows them to operate synchronously. The connection between the synchronous belts and the conveyor belt ensures uninterrupted operation. The first sealing strip adheres to the outer side of the conveyor belt, and the second sealing strip adheres to the inner side, improving sealing during sludge transport and reducing the risk of leakage. The uninterrupted operation of the conveyor belt ensures continuous and stable transport, increasing the amount of sludge processed per unit time and thus improving transport efficiency. A spring-loaded sliding plate lifts a scraper, causing its top to contact the bottom surface of the conveyor belt, scraping away the sludge adhering to the belt surface. The scraped sludge is guided to the right side through a guide bucket for discharge, preventing it from adhering to the conveyor belt surface and dripping during belt rotation.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0026] Example 1: A dredging device for waterway improvement projects, please refer to [link / reference]. Figure 2 , Figure 4 and Figure 5 The system includes a base plate 1, on the upper surface of which two support plates 2 are fixedly mounted. A geared motor 3 is fixedly mounted on the front of one of the support plates 2. Two connecting rods 4 and two synchronous belts 7 are located above the base plate 1. The output shaft of the geared motor 3 is fixedly connected to the end of the corresponding connecting rod 4. The support plates 2 are fixedly mounted on the upper surface of the base plate 1. The geared motor 3 is positioned on the front of one of the support plates 2. The connecting rods 4 and synchronous belts 7 are positioned above the base plate 1. The output shaft of the geared motor 3 is fixed to the end of the left connecting rod 4, allowing the geared motor 3 to drive the connecting rod 4 to rotate. The outer surface of each connecting rod 4 is rotatably connected to the inner wall of the corresponding support plate 2. This rotatable connection allows the support plate 2 to limit the movement of the connecting rod 4. Two pulleys 5 are fixedly connected to the outer surface of each rod 4. Each pulley 5 meshes with a corresponding synchronous belt 7. A support platform 6 is fixedly installed between the two support plates 2. The outer surface of each connecting rod 4 is rotatably connected to the inner wall of the support platform 6. The pulleys 5 are installed on the outer surface of the connecting rod 4 and meshed with the synchronous belts 7, so that when the connecting rod 4 rotates, it can drive the pulleys 5 to rotate. Through the connection between the pulleys 5 and the synchronous belts 7, when the reduction motor 3 drives the connecting rod 4 to rotate, the two synchronous belts 7 can operate synchronously. A conveyor belt 8 is provided above the base plate 1. The outer surface of each synchronous belt 7 is riveted to the inner wall of the conveyor belt 8. The conveyor belt 8 is set above the base plate 1, and the conveyor belt 8 is fixed to the corresponding synchronous belt 7 by riveting, so that when the synchronous belt 7 operates, it can drive the conveyor belt 8 to operate.

[0027] Please see Figure 3 , Figure 4 and Figure 5Each support plate 2 has an installation strip 9 fixedly connected to its adjacent side. A first sealing strip 10 is fixedly installed on the bottom surface of each installation strip 9. Two second sealing strips 11 are fixedly installed on the outer surface of the support platform 6. Each first sealing strip 10 and second sealing strip 11 is in contact with the conveyor belt 8. The installation strip 9 is installed on the adjacent side of the support plate 2, and the first sealing strip 10 is installed on the inner wall of the installation strip 9. The second sealing strip 11 is set on the outer surface of the support platform 6. Since the inner wall of the conveyor belt 8 is in contact with the second sealing strip 11 and the outer surface of the conveyor belt 8 is in contact with the first sealing strip 10, the edges of the conveyor belt 8 can be sealed by the first sealing strip 10 and the second sealing strip 11 when the conveyor belt 8 is transporting sludge. This device can improve the sealing performance when transporting sludge, reduce the risk of sludge leakage, and ensure that the conveyor belt 8 operates continuously, thus ensuring a continuous and stable transport process, increasing the amount of sludge processed per unit time, and thereby improving transportation efficiency.

[0028] Example 2: A dredging device for waterway improvement projects, please refer to [link / reference]. Figure 1 , Figure 3 and Figure 5 The upper and lower surfaces of the support platform 6 are fixedly connected to bearing plates 12. The side of each bearing plate 12 that is away from each other slides in contact with the inner wall of the conveyor belt 8. The bearing plates 12 are installed on the upper and lower surfaces of the support platform 6, forming a fixed connection. The bearing plates 12 are in contact with the conveyor belt 8, allowing them to support the conveyor belt 8. The support platform 6 is slightly lower than the bearing plates 12, allowing the synchronous belt 7 to fit against the surface of the support platform 6, thus supporting both the synchronous belt 7 and the conveyor belt 8. A support frame 13 is fixedly installed on the bottom surface of the base plate 1. A transfer chamber 14 is located above the base plate 1. The front and back of the transfer chamber 14 are fixedly connected to... The support frame 17 is installed on the bottom surface of the base plate 1 to support the base plate 1 and the upper components. The transfer chamber 14 is set above the base plate 1, and the limiting frame 17 is installed on the front and back of the transfer chamber 14. The transfer chamber 14 can hold sludge, and the limiting frame 17 can support the transfer chamber 14. The bottom surface of the transfer chamber 14 is fixedly connected to the discharge pipe 15, and the outer surface of the discharge pipe 15 is fixedly installed with a valve 16. The discharge pipe 15 is installed on the bottom surface of the transfer chamber 14, and the valve 16 is installed on the outer surface of the discharge pipe 15. Through the cooperation of the discharge pipe 15 and the valve 16, the sludge inside the transfer chamber 14 can be easily discharged.

[0029] Please see Figure 1 , Figure 2 and Figure 6A mounting base 18 is fixedly connected to the right side of the support frame 13. A limiting shell 19 is fixedly connected to the upper surface of the mounting base 18. The mounting base 18 is installed on the right side of the support frame 13, and the limiting shell 19 is installed on the upper surface of the mounting base 18 to support the limiting shell 19. A sliding plate 20 is slidably connected to the inner wall of the limiting shell 19. A scraper 21 is fixedly connected to the upper surface of the sliding plate 20. The sliding plate 20 is installed on the inner wall of the limiting shell 19, forming a sliding connection to limit the sliding plate 20. The scraper 21 is then fixedly connected to the upper surface of the sliding plate 20. 21 is installed on the upper surface of the slide plate 20 and is fixedly connected so that the slide plate 20 can rise and fall together with the scraper 21. The top part of the scraper 21 contacts the bottom surface of the conveyor belt 8 so that when the conveyor belt 8 rotates, the scraper 21 can scrape off the attached sludge. A guide bucket 22 is fixedly connected to the right side of the scraper 21. The guide bucket 22 is positioned on the right side of the scraper 21. After the sludge is scraped off, the guide bucket 22 can guide the sludge to the right side for discharge.

[0030] Please see Figure 1 , Figure 2 and Figure 6 The inner bottom wall of the limiting shell 19 is fixedly connected with guide rods 23 and springs 24 arranged at equal intervals. The outer surface of each guide rod 23 is slidably connected to the inner wall of the slide plate 20, and the top of each spring 24 is fixedly connected to the bottom surface of the slide plate 20. The guide rods 23 and springs 24 are set on the inner bottom wall of the limiting shell 19, and the outer surface of the guide rod 23 is connected to the slide plate 20 in a sliding connection to improve the stability of the slide plate 20 when it is raised and lowered. The top of the spring 24 is fixed to the bottom surface of the slide plate 20 so that the spring 24 can always press against the slide plate 20, ensuring that the scraper 21 is always in contact with the bottom surface of the conveyor belt 8.

[0031] It should be noted that both the first sealing strip 10 and the second sealing strip 11 are made of polyurethane, which has high strength, high elasticity and good wear resistance. They can always be in contact with the surface of the conveyor belt 8 when the conveyor belt 8 is in operation. When conveying sludge, the reduction motor 3 always keeps rotating at a low speed to achieve low-speed operation of the conveyor belt 8.

[0032] The implementation principle of this application embodiment is as follows: A carrier is placed at the tail of the conveyor belt 8, and then valve 16 is opened, allowing the sludge in the transfer chamber 14 to be discharged through the discharge pipe 15. The sludge falls onto the surface of the conveyor belt 8. At this time, the reduction motor 3 is started to drive the connecting rod 4 to rotate, which in turn drives the pulley 5 to rotate. The pulley 5 is connected to the synchronous belt 7, enabling the two synchronous belts 7 to operate synchronously. The riveting of the synchronous belts 7 to the conveyor belt 8 allows the conveyor belt 8 to move the sludge. During the sludge transport process, the first sealing strip 10 and the second sealing strip 11, located on the upper surface and inner side of the conveyor belt 8, can interact with the conveyor belt... The 8-fold fit improves the sealing performance during sludge transport, reducing the risk of sludge leakage. The continuous operation of the conveyor belt 8 ensures a continuous and stable transport process, increasing the amount of sludge processed per unit time and thus improving transport efficiency. At this time, the sludge is transferred to the tail end of the conveyor belt 8 and falls directly into the carrier at the tail end. Under the action of the spring 24, the slide plate 20 is pressed tightly, so that the scraper 21 can always contact the bottom surface of the conveyor belt 8, thereby scraping off the sludge adhering to the surface of the conveyor belt 8. The scraped sludge is transferred to the carrier through the guide bucket 22, thereby preventing the sludge from dripping as the conveyor belt 8 rotates.
