Abstract
Description
Technical Field
[0001] This utility model relates to the field of river dredging technology, specifically to a river dredging device. Background Technology
[0002] River dredging equipment is a type of mechanical equipment used to remove silt and debris from the bottom of rivers, lakes, reservoirs and other bodies of water. With the acceleration of urbanization, a large amount of domestic waste has accumulated in many rivers. When domestic waste mixes with the silt at the bottom of the river, it causes a certain degree of pollution to the river water. Regularly dredging rivers can purify the river water and maintain the aquatic ecological environment.
[0003] Traditional river dredging methods mainly rely on manual labor or simple mechanical operations, which are inefficient and cause some damage to the environment. With the advancement of technology, existing dredging devices often use grab bucket dredging devices to grab silt from the riverbed and transport it to both sides of the river for accumulation, which can save a lot of manpower. However, grab bucket dredging devices require manual operation of the grab machine and control of the grab bucket. After continuous operation, the manual labor intensity is high, and the grab bucket swings back and forth, resulting in greater wear and tear, which is not conducive to continuous operation. Utility Model Content
[0004] The purpose of this invention is to provide a river dredging device to address the aforementioned shortcomings in the technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

A feed plate is provided below the top plate. An extension plate is fixed to one end of the feed plate. A screen plate is fixed to the end of the extension plate. A sludge collection trough is opened at the top of the screen plate. A drain hole is opened downward at the top of the sludge collection trough. A suction pipe is provided on one side of the sludge collection trough. A suction pump is fixed to the end of the suction pipe. The discharge port of the suction pump is connected to a discharge pipe. An air pump is also provided at the top of the top plate. An air pipe is connected to the air outlet of the air pump and extends downward from the top plate.

[0010] Preferably, a fixing plate is fixed to one end of the base, and a connecting rod is fixed to one side of the top of the fixing plate.
[0011] Preferably, a connecting seat is fixed on one side of the vehicle body, and an insertion hole is provided on the side wall of the connecting seat. The extension end of the connecting rod can be inserted into the insertion hole and fixed by bolts.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] Air is blown into the riverbed through a set air pipe, which agitates the silt from the riverbed. The vehicle body pushes the feed plate, extension plate, and screen plate forward. The silt mixed with the water passes through the feed plate and extension plate, and then reaches the screen plate. The silt is then extracted from the collection tank located on the screen plate through the suction pipe. As the feed plate, extension plate, and screen plate continue to move forward, the silt in the river can be continuously extracted. During the silt extraction process, the river water flows down through the screen plate, which can reduce the amount of river water extracted and facilitate the separation of silt from river water.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0029] This utility model provides, for example Figure 1 - Figure 7 The river dredging device shown includes a vehicle body 1. A dredging mechanism is provided on one side of the vehicle body 1. The dredging mechanism includes a top plate 5. A feed plate 14 is provided below the top plate 5. An extension plate 15 is fixed to one end of the feed plate 14. A screen plate 16 is fixed to the end of the extension plate 15. A sludge collection trough 161 is provided on the top of the screen plate 16. A drain hole 19 is provided on the top of the sludge collection trough 161. A suction pipe 8 is provided on one side of the sludge collection trough 161. A suction pump 9 is fixed to the end of the suction pipe 8. A discharge pipe 10 is connected to the discharge port of the suction pump 9.
[0030] An air pump 11 is also installed at the top of the top plate 5. The air outlet of the air pump 11 is connected to an air pipe 12, which extends downwards from the top plate 5.
[0031] A feeding cloth 17 is provided on the top of the extension plate 15, and multiple pushing components 13 are provided between the extension plate 15 and the feeding cloth 17. Side plates 6 are fixed on both sides of the extension plate 15.
[0032] In this embodiment, it should be noted that the feed plate 14, extension plate 15 and screen plate 16 are inclined below the top plate 5. During the dredging process, the vehicle body 1 pushes the feed plate 14, extension plate 15 and screen plate 16 forward. The vehicle body 1 travels on the riverbank. At the same time, the feed plate 14, extension plate 15 and screen plate 16 are located above the river channel, and the end of the feed plate 14 extends into the water.
[0033] The air pump 11 is started, and the air pump 11 inflates the air pipe 12. The air is blown into the silt in the river channel. The silt is underwater and is agitated by the air. It then mixes with the water. As the feed plate 14 moves forward, it guides the water mixed with silt to the feeding cloth 17 above the extension plate 15. After passing through the feeding cloth 17, the silt water reaches the sludge collection tank 161. The silt water flows downward into the river channel through the leakage hole 19. The silt remains in the sludge collection tank 161. At the same time, the suction of the suction pump 9 is used to extract the silt from the suction pipe 8 and discharge the silt to the riverbank next to the river channel or to the transport vehicle on the riverbank. The transport vehicle is located at the extension end of the discharge pipe 10.
[0034] like Figure 1 - Figure 7 As shown, each pushing component 13 includes a motor 133 fixed to the outer wall of one side of the side plate 6. The output shaft end of the motor 133 is connected to a main shaft 132, and a push rod 131 is fixed to the outer wall of the main shaft 132. Specifically, after the motor 133 is started, the motor 133 drives the main shaft 132 to rotate, and the main shaft 132 drives the two push rods 131 to rotate. During the rotation of the push rods 131, they alternately contact the feeding cloth 17 and push the sludge on the feeding cloth 17. The sludge moves to the side of the screen plate 16.
[0035] like Figure 1 - Figure 7 As shown, a base 7 is fixed to the end of the sieve plate 16. A through hole 162 is provided on the side of the sieve plate 16 near the base 7. A hole is provided inside the base 7. The through hole 162 communicates with the hole. The suction pipe 8 can pass through the hole and the through hole 162. Specifically, the end of the suction pipe 8 is located in the sludge collection tank 161. The suction pipe 8 passes through the through hole 162 and through the hole in the base 7. It extends upward and is connected to the suction pump 9. After the suction pump 9 is started, the sludge in the sludge collection tank 161 is sucked into the suction pipe 8.
[0036] like Figure 1 - Figure 7 As shown, a fixing plate 4 is fixed to one end of the base 7, and a connecting rod 3 is fixed to one side of the top of the fixing plate 4. Specifically, after the base 7 and the fixing plate 4 are fixed with bolts, they are then fixed to the screen plate 16. When the fixing plate 4 moves, it drives the base 7 and the screen plate 16 to move synchronously.
[0037] like Figure 1 and Figure 4As shown, a connecting seat 2 is fixed on one side of the vehicle body 1. An insertion hole 18 is provided on the side wall of the connecting seat 2. The extension end of the connecting rod 3 can be inserted into the insertion hole 18 and fixed by bolts. Specifically, in actual use, the vehicle body 1 can be a heavy vehicle such as an excavator or a loader. The connecting seat 2 is fixed on the mechanical arm of the vehicle body 1 by bolts, so that the connecting seat 2 is stable and does not shake. The vehicle body 1 drives the connecting seat 2 to move, thereby allowing the connecting rod 3 to move. During the movement of the connecting rod 3, the fixed plate 4 moves, thereby driving the dredging device of this application to move.
[0038] By adjusting the position of the connecting rod 3 in the insertion hole 18, the distance between the top plate 5 and the vehicle body 1 can be adjusted, making it easier for the vehicle body 1 to move the dredging device closer to the river channel, thus facilitating the placement of the dredging device into the river water.
[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
