DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the utility model.

[0023] As shown in Figure 1 , Figure 2 A device for channel dredging, comprising: a connecting platform 1 connected with an engineering ship; a collecting bin 2 arranged at the bottom of the connecting platform 1; a dredging wheel 3 arranged at the front end of the collecting bin 2; a collecting plate 4 rotatably connected to the bottom of the collecting bin 2; an extension plate 5 arranged at the front end of the connecting platform 1, the bottom of the extension plate 5 being provided with a guide plate 51; a detection tooth 6 slidingly connected to the guide plate 51; and a suction pipe 7 penetrating through the top of the collecting bin 2.

[0024] The top of the connecting platform 1 is provided with a connecting column 11, the connecting column 11 is connected with the engineering ship, the connecting column 11 is provided with a control wire inside, and the control wire transmits the electrical signal of the engineering ship. When the engineering ship on the river moves, the connecting column 11 is driven to move together, so that the device is dredged along the direction of the channel, and the control wire transmits the control signal on the engineering ship to the device, so that the mechanical parts on the device work.

[0025] The front side wall and the front end of the bottom of the collecting bin 2 are provided with an opening, and the rear side wall and the rear end of the bottom of the collecting bin 2 are provided with a water permeable hole 21. When the device moves forward, the mixture of mud and water dug is entered into the collecting bin 2 from the opening, and with the movement of the device, the water flows out of the water permeable hole 21 of the rear side wall, most of the river bottom mud is collected by the collecting bin 2, and when the device is moved upward, the water flows out of the water permeable hole 21 of the bottom, and the collected river bottom mud is left in the collecting bin 2.

[0026] The side wall of the dredging wheel 3 is annularly arranged with a plurality of dredging teeth 31, the front part and the bottom of the dredging wheel 3 protrude from the collecting bin 2, and the dredging wheel 3 is driven by a first motor 32. The first motor 32 is an underwater motor, and after the first motor 32 drives the dredging wheel 3 to rotate, the dredging teeth 31 are in contact with the river bottom, the river bottom mud is loosened and scooped, and part of the silt is directly brought into the collecting bin 2, and with the forward movement of the collecting bin 2, the floating river bottom mud also enters the collecting bin 2.

[0027] The collecting plate 4 is arranged behind the dredging wheel 3, and the collecting plate 4 is driven by a second motor 42, which is also an underwater motor. When the collecting plate 4 rotates downward, the opening at the bottom of the collecting bin 2 is opened, so that the river bottom mud can enter the collecting bin 2. When the collecting plate 4 rotates to be parallel to the bottom surface of the collecting bin 2, the sludge cannot enter the collecting bin 2 any more, and the sludge collected in the collecting bin 2 cannot flow out any more. The front end of the collecting plate 4 is provided with a bending plate 41, which is 120 degrees with the collecting plate 4. When the collecting plate 4 is unfolded, the bending plate 41 is parallel to the river bottom.

[0028] The lower part of the bending plate 41 is provided with a supporting cone 43. When dredging, the bottom of the supporting cone 43 is lower than the dredging wheel 3. The bottom of the supporting cone 43 is a pointed end. When the dredging wheel 3 is working, the supporting cone 43 is inserted into the river bottom. If the river bottom is muddy or contains a small amount of stones, the supporting cone 43 can enter smoothly, and the dredging wheel 3 can work normally. If the river bottom is large rocks, the supporting cone 43 cannot be inserted, thereby protecting the dredging teeth 31 from colliding with the large rocks.

[0029] The guide plate 51 is perpendicular to the extension plate 5, and the guide plate 51 is arranged in front of the dredging wheel 3. The guide plate 51 is located in the middle of the bottom surface of the extension plate 5. The guide plate 51 is a hollow plate, and the bottom of the guide plate 51 is provided with an opening. The side wall of the guide plate 51 is provided with a vertical track 511, which is not communicated with the bottom of the guide plate 51. The bottom surface of the guide plate 51 is located above the bottom surface of the dredging wheel 3.

[0030] The detection tooth 6 is slidingly connected to the hollow part of the guide plate 51. The detection tooth 6 can slide downward to penetrate into the river bottom mud. The side wall of the detection tooth 6 is provided with a control rod 61, which penetrates through the vertical track 511 and is slidingly connected to the vertical track 511. The top of the control rod 61 penetrates through the extension plate 5. The control rod 61 is provided with a rack 611. The top surface of the extension plate 5 is provided with a third motor 62, which is also an underwater motor. The output end of the third motor 62 is fixedly connected with a pinion 621, which is engaged with the rack 611. In use, the third motor 62 is started to drive the pinion 621 to drive the rack 611 to ascend and descend, and further drive the detection tooth 6 to ascend and descend. When the detection tooth 6 penetrates into the river bottom, the bottom mud is loosened, which is convenient for the dredging wheel 3 to dredge the river bottom mud. When the detection tooth 6 contacts with large rocks in the river bottom, the detection tooth 6 cannot penetrate downward any more. At this time, the whole device is lifted up, so that the dredging wheel 3 floats up to avoid contacting with the rocks. The detection tooth 6 and the supporting cone 43 cooperate to avoid the damage of the dredging teeth 31 during dredging, and automatically avoid contacting with the rocks during working.

[0031] The top of the suction pipe 7 is connected with the engineering ship, and the side wall of the suction pipe 7 is fixedly connected with the bottom of the connecting platform 1. When the operation in deep water is carried out, the suction pipe 7 can be started to suck the silt in the collecting bin 2 to the engineering ship for subsequent transportation; when the dredging in shallow water is carried out, the dredging wheel 3 loads the silt in the collecting bin 2, the second motor 42 is started to close the collecting plate 4, then the device is lifted to above the water surface, and the river bottom mud in the collecting bin 2 is unloaded.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of the present application.
