[0002] River siltation has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. In order to restore the normal functions of rivers and promote rapid and sustainable economic and social development, river dredging projects are carried out to make rivers deeper and wider and the water clearer through management. The production conditions and living environment of the masses are significantly improved. River dredging generally refers to river management, which is a water conservancy project. Through mechanical equipment, the silt deposited on the riverbed is blown and stirred into turbid water, which flows away with the river water, thereby playing a role in dredging.

[0003] During the cleaning process, the existing cutter suction type river channel dredging device will inevitably be blocked by debris such as stones, aquatic plants and plastics on the riverbed, resulting in reduced dredging efficiency of the dredging device. After the existing cutter suction type river channel dredging device is blocked, the dredging pipe needs to be dismantled before the blocked pipe can be cleaned, which is inefficient. Summary of the invention

DETAILED DESCRIPTION

[0022] like Figure 1-2As shown, a suction-type river channel dredging device that is easy to maintain includes a mounting seat 2, which is an L-shaped plate. A moving component and a dredging component are installed on the front of the mounting seat 2, and a lifting component is installed on the back of the mounting seat 2.

[0023] like Figure 1-4 As shown, the moving assembly includes a mounting frame 6, which is a U-shaped structure, and the mounting frame 6 is fixed to the lower front part of the mounting seat 2. Two bidirectional threaded rods 9 are rotatably installed in the interior of the mounting frame 6 at intervals on the left and right sides along the length direction, and the threads on the bidirectional threaded rods 9 are divided into two sections on the left and right, and the threads of the two sections are in opposite directions. Two moving plates 20 are threadedly connected to the two bidirectional threaded rods 9, and when the two bidirectional threaded rods 9 rotate, the two moving plates 20 are relatively close to or away from each other. U-shaped plates 8 are fixed to the opposite sides of the two moving plates 20, and the two U-shaped plates 8 are mirror-symmetrical to each other. A spliced ​​semicircular tube 7 is fixed to each U-shaped plate 8, and a feed port 18 is provided at the lower end of the spliced ​​semicircular tube 7.

[0024] like Figure 1-2 As shown, in order to realize the closing or opening of the two spliced ​​semicircular tubes 7, a second motor 5 is fixed on the side of the mounting frame 6, and a driving gear 17 is fixed on the output end of the second motor 5. The driving gear 17 is meshed with two driven gears 16 respectively, and the two driven gears 16 are fixed on the ends of the two bidirectional threaded rods 9 accordingly. The second motor 5 drives the driving gear 17 to rotate, and the driving gear 17 drives the two driven gears 16 to rotate synchronously, and the two driven gears 16 drive the bidirectional threaded rods 9 at the corresponding positions to rotate synchronously. When the two bidirectional threaded rods 9 rotate, the two moving plates 20 are relatively close to or away from each other, which will drive the two U-shaped plates 8 and the two spliced ​​semicircular tubes 7 to be relatively close to or away from each other. After the two spliced ​​semicircular tubes 7 are close to each other, they will gradually close to form a circular tube; after the two spliced ​​semicircular tubes 7 are opened, an opening can be formed.

[0025] like Figure 1 As shown, in addition, a spliced ​​arc plate 4 and a spliced ​​discharge plate 10 are respectively fixed on the upper side walls of the two spliced ​​semicircular tubes 7.

[0027] The first motor 1 drives the rotating shaft 3 to rotate through the output shaft, and the rotating shaft 3 drives the auger 19 to rotate. The auger 19 cooperates with the two spliced ​​semicircular tubes 7 to transport the silt at the bottom of the river channel to the top of the spliced ​​semicircular tubes 7 through the feed port 18.

[0028] like Figure 1 As shown, the lifting assembly includes a fixing plate 11, which is fixed on the hull, an L-shaped support plate 12 is hinged above the fixing plate 11, an electric push rod 13 is fixed above the L-shaped support plate 12, an L-shaped connecting plate 14 is fixed above the electric push rod 13, and the L-shaped connecting plate 14 is fixed to the side of the mounting seat 2. A traction block 15 is fixed above the L-shaped connecting plate 14, and the traction block 15 is connected to the traction machine on the hull through a connecting rope.

[0029] The traction machine drives the traction block 15 to move through the connecting rope, the traction block 15 drives the mounting seat 2 to rotate, the mounting seat 2 drives the mounting frame 6 to rotate, so that the two spliced ​​semicircular tubes 7 are rotated into a horizontal state; at the same time, the electric push rod 13 extends to drive the L-shaped connecting plate 14 to move, the L-shaped connecting plate 14 drives the mounting seat 2 to move, and finally the device is moved to the hull.

[0030] Working principle and process:

[0031] 1) The first motor 1 drives the rotating shaft 3 to rotate through the output shaft, and the rotating shaft 3 drives the auger 19 to rotate. The auger 19 cooperates with the two spliced ​​semicircular tubes 7 to transport the silt at the bottom of the river channel to the top of the spliced ​​semicircular tubes 7 through the feed port 18. The spliced ​​arc plate 4 and the spliced ​​discharge plate 10 cooperate to discharge the cleared silt onto the loading ship, thereby facilitating the collection of the cleared silt.

[0032] 2) When the auger 19 and the two spliced ​​semicircular tubes 7 are blocked by debris such as stones, water plants and plastics on the riverbed, the connecting rope is reeled in by the traction machine, the connecting rope drives the traction block 15 to move, the traction block 15 drives the mounting seat 2 to rotate, the mounting seat 2 drives the mounting frame 6 to rotate, so that the two spliced ​​semicircular tubes 7 are rotated into a horizontal state, the electric push rod 13 extends to drive the L-shaped connecting plate 14 to move, the L-shaped connecting plate 14 drives the mounting seat 2 to move, the mounting seat 2 drives the rotating shaft 3 to move, and the rotating shaft 3 drives the auger 19 to move onto the hull.

[0033] The second motor 5 drives the driving gear 17 to rotate through the output shaft, and the driving gear 17 drives the two driven gears 16 to rotate synchronously, and the two driven gears 16 drive the bidirectional threaded rods 9 at the corresponding positions to rotate, and the bidirectional threaded rods 9 drive the two movable plates 20 to move in the opposite direction synchronously, and the movable plate 20 drives the U-shaped plate 8 to move, and the two U-shaped plates 8 drive the spliced ​​semicircular tubes 7 at the corresponding positions to move in the opposite direction, thereby releasing the limit on the auger 19, and facilitating the cleaning and maintenance of the auger 19 and the inside of the spliced ​​semicircular tube 7.
