Description
Technical Field
[0001] This utility model relates to the field of drainage ditch construction technology, specifically a drainage ditch construction dredging device. Background Technology
[0002] A drainage ditch is a facility used to guide and manage water flow. It is typically a linear channel, ditch, or trench designed to collect, guide, and discharge rainwater, surface water, and other liquids. Its primary purpose is to prevent waterlogging and flooding, reduce the risk of flooding, and protect buildings, roads, facilities, and the environment. Drainage ditches are commonly used in various locations, including urban roads, industrial areas, commercial areas, parking lots, open squares, and residential areas. During the flood season, drainage ditches around construction sites often accumulate a certain thickness of silt due to continuous rainfall. Silt accumulation slows down the water flow, and the silt buildup exacerbates this slowing effect. In severe cases, it can lead to blockages. Therefore, it is necessary to clean the silt inside the drainage ditch during construction.
[0003] During dredging, silt is usually pumped out of the drainage ditch. However, the silt often contains impurities such as dead branches, fallen leaves, and aquatic plants, which can easily clog the dredging pipes. The silt at the bottom of the drainage ditch tends to settle and solidify, making it difficult to pump out and affecting the smooth progress of the dredging work. Moreover, after the silt is discharged, it is inconvenient to clean the residual silt on the inner wall of the silt tank used for temporary storage. Once the silt has solidified, it is very difficult to deal with. Therefore, we propose a dredging device for drainage ditch construction. Utility Model Content
[0004] The purpose of this invention is to provide a drainage ditch dredging device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage ditch dredging device, including a dredging vehicle, and further comprising...
[0006] A dredging pump, which is installed on one side inside the dredging vehicle;
[0007] A sludge tank is installed on the top of a sludge removal vehicle. A lifting housing is fixed to the top of the sludge tank. A lead screw and a guide rod are respectively installed on both sides inside the lifting housing. The top of the lead screw is fixedly connected to the output end of the second motor at the top of the lifting housing. A T-shaped frame is provided inside the lifting housing.
[0008] A scraping mechanism is provided on the top of the sludge tank. The scraping mechanism includes a third motor, a rotating rod, and scrapers. The rotating rod is installed at the output end of the third motor on the top of the sludge tank, and the scrapers are fixed at both ends of the rotating rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] The first cylinder drives the horizontal arm to move downwards, causing the barrier net to extend into one end of the drainage ditch. The crushing rod extends into the drainage ditch on one side of the barrier net. The first motor drives the crushing rod to rotate, causing the crushing blades to rotate and crush impurities in the silt inside the drainage ditch. At the same time, it disperses the silt at the bottom and mixes the silt evenly. The dredging vehicle travels along the drainage ditch. Under the interception of the barrier net, the dispersed silt can pass through the barrier net. Large pieces of silt and impurities are intercepted by the barrier net and continue to be crushed by the crushing blades until the large pieces of silt are completely dispersed and the impurities are completely crushed. The second cylinder drives the pipe sleeve to move downwards, extending the corrugated telescopic pipe into the side of the barrier net away from the crushing rod. The corrugated telescopic pipe extends into the drainage ditch, and the dredging pump is started to suck out the silt after crushing and dispersing and put it into the silt tank. By crushing and dispersing the silt for pretreatment, pipe blockage can be effectively prevented and the dredging work can be carried out smoothly.
[0020] Opening the valve allows the sludge inside the sludge tank to be discharged through the drain pipe. After the sludge is emptied, the second motor drives the lead screw to rotate, causing the T-shaped frame to move the scraping mechanism downward. The third motor drives the rotating rod to rotate the scraper. As the scraper moves downward, it rotates along the inner wall of the sludge tank, scraping off the residual sludge on the inner wall. The scraped sludge is discharged through the drain pipe, which facilitates the quick cleaning of the residual sludge on the inner wall of the sludge tank and prevents the sludge from solidifying.

[0034] Specifically, the first cylinder 5 is activated to drive the horizontal arm 8 to move downward, so that the barrier net 9 extends into one end of the drainage ditch 14, and the crushing rod 10 extends into the drainage ditch 14 on one side of the barrier net 9. The first motor 7 drives the crushing rod 10 to rotate, so that the crushing blade 11 rotates, crushing the impurities in the silt inside the drainage ditch 14, and at the same time breaking up the silt at the bottom and mixing the silt evenly.
[0035] Next, the sludge removal vehicle 1 travels along the drainage ditch 14. Under the interception of the net 9, the dispersed sludge can pass through the net 9. Large pieces of sludge and impurities are intercepted by the net 9 and continue to be crushed by the crushing blades 11 until the large pieces of sludge are completely dispersed and the impurities are completely crushed.
