[0002] River desilting refers to the process of removing sediment, silt and other impurities deposited at the bottom of rivers, lakes or reservoirs. This work is of great significance for maintaining the navigability of waterways, improving water quality, reducing the risk of flood disasters and protecting the ecological environment.

[0003] In the traditional river channel desilting process, an excavator is usually used to excavate the silt. However, during the excavation process, each time the excavator bucket is filled with silt, it is necessary to control the bucket to move to the shore, then dump the silt, and then control the bucket to reset and excavate. This working method wastes a lot of time in the transportation and dumping of silt, affecting work efficiency, and needs to be improved. Summary of the invention

Detailed implementation mode

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] As Figure 1 , Figure 2 shown, a dredging device for river channels includes a bucket 1, a pair of sludge pumps 2, a plurality of suction pipes 3 and a sludge scraping mechanism 4.

[0028] As Figure 1 , Figure 2 shown, the bucket 1 is arranged in a long strip shape and is open on one side. A cover plate 11 is arranged on the bucket 1, one side of the cover plate 11 is rotatably connected to the upper end of the bucket 1, and the cover plate 11 is used to cover the opening position of the bucket 1 after being turned over.

[0029] As Figure 1 , Figure 2 shown, a pair of sludge pumps 2 are respectively arranged on both sides of the upper end position of the bucket 1, and a plurality of suction pipes 3 are arranged at intervals on the side wall of the upper end position of the bucket 1. A screw conveyor 5 is arranged between the sludge pump 2 and the suction pipe 3, a plurality of suction pipes 3 are connected to the screw conveyor 5, and the outlet end of the screw conveyor 5 is connected to the inlet end of the sludge pump 2.

[0030] As Figure 1 , Figure 2 shown, a flushing pipe 51 is arranged at the outlet end position of the screw conveyor 5, and the screw conveyor 5 can be controlled to rotate reversely to realize the reverse flushing of the screw conveyor 5 and the bucket 1, so as to ensure the cleanliness of the whole dredging device.

[0031] As Figure 2 , Figure 3 shown, the sludge scraping mechanism 4 is arranged in the bucket 1 and is used to push the sludge in the bucket 1 into the suction pipe 3. The sludge scraping mechanism 4 includes a pair of scrapers 41 and a drive mechanism 43.

[0032] As Figure 2 , Figure 3 shown, a pair of scrapers 41 are arranged side by side at the middle position of the bucket 1 and are slidably connected to the inner wall of the bucket 1. Scraping bars 42 that abut against the inner side of the cover plate 11 are arranged on the scrapers 41.

[0033] As Figure 2 , Figure 3As shown, the driving mechanism 43 is used to control the relative sliding of a pair of scrapers 41. The driving mechanism 43 includes a rotating shaft 44, a motor 45, a pair of driving rods 46, and a slider 47.

[0034] As Figure 2 , Figure 3 shown, the rotating shaft 44 is vertically rotatably connected to the middle position of the bucket 1, and the motor 45 is used to control the rotation of the rotating shaft 44. A pair of driving rods 46 are rotatably connected to both ends of the rotating shaft 44, and the slider 47 is rotatably connected to both ends of the driving rod 46 and slidably connected to the side where the scrapers 41 are close to each other.

[0035] As Figure 2 , Figure 3 shown, overlapping baffles 48 are bent at the outer edge positions of a pair of scrapers 41. The baffles 48 are used to cover the driving mechanism 43 to prevent silt from contaminating the driving mechanism 43 and ensure the normal operation of the driving mechanism 43. The baffles 48 are arranged in an inclined plane and slope downward towards both ends of the bucket 1 to achieve the guiding of silt and enable the silt to smoothly enter the bucket 1.

[0036] When it is necessary to clean the silt in the river channel, the entire bucket 1 is connected to the boom of the excavator, and then the cover plate 11 is controlled to flip to open the opening position of the bucket 1. Then, the boom of the excavator drives the bucket 1 to move and excavate the silt.

[0037] After excavation, the bucket 1 is controlled to flip so that the opening position faces upward, and then the cover plate 11 is controlled to flip in the reverse direction so that the cover plate 11 covers the bucket 1. Then, the motor 45 is started to drive the rotating shaft 44 to rotate. The rotating shaft 44 drives a pair of driving rods 46 to rotate synchronously, and under the action of the rotatably connected slider 47, a pair of scrapers 41 are controlled to move away from each other.

[0038] At the same time, the scrapers 41 push the silt in the bucket 1 to both ends of the bucket 1 and scrape the silt on the inner side of the cover plate 11 to ensure the self-cleaning of the cover plate 11. And the scrapers 41 enable the silt to pass through each suction pipe 3. At this time, the screw conveyor 5 works to push the silt in the suction pipe 3 to the outlet end position of the screw conveyor 5, and under the action of the silt pump 2, the silt is sucked and discharged.

[0039] When the silt in each bucket 1 is sucked out, the motor 45 is started to drive the rotating shaft 44 to rotate in the reverse direction. The rotating shaft 44 drives a pair of driving rods 46 to rotate synchronously in the reverse direction, and under the action of the rotatably connected slider 47, a pair of scrapers 41 are controlled to move closer to each other and reset.

[0040] Meanwhile, the baffles 48 on the scraping plate 41 overlap each other to cover the driving mechanism 43, and then the cover plate 11 is controlled to turn over in the reverse direction to open the opening position of the bucket 1. Then, the boom of the excavator drives the bucket 1 to continue moving and further excavate the silt.

[0041] Therefore, by providing the bucket 1 with the silt pump 2, after the bucket 1 is filled with silt each time, the silt pump 2 can quickly suck the silt in the bucket 1 and transport it over a long distance, without the need to control the bucket 1 to move to the shore and dump the bucket 1, saving time, achieving continuous excavation and transportation of the silt, and improving the construction efficiency.

[0042] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
