Description

Technical Field

[0001] This application relates to the technical field of water conservancy and river dredging equipment, and in particular to a cutter suction dredging vessel. Background Technology

[0002] Currently, cutter suction dredging vessels are one of the commonly used equipment for dredging waterways. They use a cutter device to disturb the silt on the riverbed and then suck out the silt through a suction pipe. They are a highly efficient and low-cost device for river cleaning.

[0003] The existing Chinese patent document with authorization announcement number CN202658640U discloses a hydraulic spiral cutter suction dredging vessel, which includes a float, a boom support, a spiral agitator installed on the boom support, and a sand suction hose installed on the boom support. The sand suction hose and the sand discharge hose are connected. The spiral agitator disturbs the silt and sand, and then the sand is suctioned through the sand suction hose.

[0004] During the river dredging process, it is not only necessary to remove river silt, but also to remove floating debris such as plastic waste. The dredging boats mentioned above can effectively dredge the riverbed, but the garbage on the river surface still requires additional manual labor to retrieve, which is labor-intensive. Summary of the Invention

[0005] To enable dredging vessels to collect garbage from river surfaces, this application provides a cutter suction dredging vessel. The technical solution adopted in this application is as follows: A cutter suction dredging vessel includes a hull and collection devices disposed on both sides of the hull. The collection devices include a support plate disposed on the side wall of the hull, a feed belt rotatably connected to the support plate, and a collection frame disposed on the support plate. The feed belt is inclined upwards away from the direction of movement of the hull, and the collection frame is located at the upper end of the feed belt. The support plate is also provided with a power component for driving the feed belt, so that when the feed belt drives the garbage to move upwards at an incline, the garbage can fall into the collection frame. By adopting the above technical solution, during the forward dredging process, the feed belt is inclined and moves upwards at an incline under the action of the power component. During the movement of the feed belt, it can carry the garbage on the water surface upwards, causing the garbage to fall into the collection frame, thereby cleaning the garbage on the water surface. Optionally, a support plate is provided on the side wall of the hull, located above the support plate. A rotating shaft is rotatably mounted on the side of the support plate away from the feeding belt, and a movable actuating plate is provided on the side wall of the rotating shaft. A first element for driving the rotating shaft to rotate is installed on the support plate, and the first element drives the actuating plate to rotate towards the hull. By adopting the above technical solution, when the hull moves, the water flow on the surface flows towards both sides of the hull, and the actuating plate rotates towards the hull, thus agitating the water flow towards the hull, allowing the garbage on the water surface to flow towards the hull, which is beneficial for the feeding belt to bring the garbage into the collection box. Optionally, an actuating component is rotatably mounted on the support plate, located between the feeding belt and the rotating shaft. When the actuating component rotates, it can sweep the garbage onto the feeding belt. By adopting the above technical solution, under the action of the actuating component, the garbage can move onto the feeding belt more quickly, thereby reducing the situation where garbage between the feeding belt and the actuating plate escapes from between the actuating plate. Optionally, the support plate has a mounting groove, and the actuating assembly includes a rotating plate rotatably connected to the mounting groove, a second element mounted on the support plate for driving the rotating plate to rotate, and actuating rods disposed on the rotating plate. Multiple actuating rods are spaced apart along the rotation axis of the rotating plate. The feeding belts are spaced apart, and the gaps between adjacent feeding belts form a space for the actuating rods to pass through. By adopting the above technical solution, the actuating rods pass through the gaps between the feeding belts when rotating, thereby helping to push debris from the water surface onto the surface of the feeding belts.Optionally, the rotating plate has a receiving cavity, and a mounting rod is slidably disposed within the receiving cavity. The sliding direction of the mounting rod is perpendicular to the rotation axis of the rotating plate. An elastic element is disposed within the receiving cavity, and a trigger element is disposed between the mounting rod and the support plate. When the actuating rod moves to the gap between the feeding belts, the trigger element drives the mounting rod to move towards the rotation axis of the rotating plate. At this time, the elastic element is compressed, providing a force to drive the mounting rod away from the rotation axis of the rotating plate. By adopting the above technical solution, when the rotating plate rotates, the mounting rod can slide away from the feeding belt under the action of the trigger element, thereby helping the actuating rod to push the waste towards the feeding belt and reducing the situation where the plastic is lifted up when the actuating rod rotates. Optionally, the rotating plate has clearance grooves on both sides that communicate with the receiving cavity. The mounting rod has abutment rods at both ends that pass through the clearance grooves. The triggering element includes a trigger strip on the support plate. The trigger block is inclined. When the actuating rod moves and the gap in the feeding belt is widened, the abutment rod can abut against the trigger strip. When the rotating plate rotates, the abutment rod moves towards the rotation axis of the rotating plate. By adopting the above technical solution, when the rotating plate rotates, the abutment rod abuts against the inclined surface, allowing the mounting rod to slide within the receiving cavity. Optionally, the elastic element includes a spring disposed within the receiving cavity. One end of the spring is connected to the end face of the receiving cavity, and the other end of the spring is connected to the mounting rod. By adopting the above technical solution, the mounting rod can be driven to reset under the elastic force of the spring, thereby realizing the reciprocating sliding of the mounting rod. Optionally, the actuating rod is rotatably connected to the mounting rod, and a insertion groove is formed on the inner end face of the receiving cavity. The actuating rod passes through the mounting rod and slidably inserts into the insertion groove. When the mounting rod slides in the receiving cavity, the actuating rod can slide in the insertion groove. The spring is sleeved on the outer wall of the actuating rod. A protrusion is provided on the end side wall of the actuating rod. A guide groove extending along the axial direction of the insertion groove is formed on the inner wall of the insertion groove. The protrusion is located in the guide groove, and an inclined groove extending circumferentially along the insertion groove is provided at the end of the guide groove away from the mounting rod. When the actuating rod slides into the insertion groove, the protrusion can slide from the guide groove into the inclined groove. By adopting the above technical solution, when the mounting rod slides, the actuating rod slides in the insertion groove, and the protrusion slides in the guide groove. The actuating rod is rotatably connected to the mounting rod, so that when the protrusion moves to the inclined groove, the actuating rod can rotate. When the actuating rod rotates, it can better separate from the garbage on the actuating rod, thereby helping the garbage to fall onto the feeding belt.In summary, this application includes at least one of the following beneficial effects: 1. Collection devices are installed on both sides of the hull. As the hull moves forward, the feed belt tilts upward, thereby driving the garbage into the collection box; 2. When the actuating plate rotates, it helps the garbage flow towards the feed belt, and when the actuating rod rotates, it helps push the garbage onto the feed belt. Furthermore, when the actuating rod is separated from the feed belt, it can slide and rotate, thereby improving the efficiency of pushing the garbage onto the feed belt. Attached Figure Description

[0007] This application discloses a cutter suction dredging vessel for river dredging. (Refer to...) Figure 1 The dredging vessel includes a hull 1 and collection devices 2 installed on both sides of the hull 1. As the hull 1 moves forward, the collection devices 2 can collect garbage from the water surface.

[0008] Reference Figure 1 and Figure 2The collecting device 2 includes a support plate 21 mounted on the side wall of the hull 1, a feeding belt 22 rotatably mounted on the support plate 21, and a collecting frame 23 disposed on the support plate 21. The support plate 21 includes a horizontal plate 211 and a vertical plate 212, which are vertically arranged and perpendicular to each other. The lower end of the feeding belt 22 is connected to the horizontal plate 211, and the upper end of the feeding belt 22 is connected to the upper end of the vertical plate 212, so that the feeding belt 22 is inclined from bottom to top. The collecting frame 23 is fixed to the upper side wall of the vertical plate 212, with the opening of the collecting frame 23 facing upward, and the opening of the collecting frame 23 is located below the upper end of the feeding belt 22. The vertical plate 212 is also equipped with a power unit 3 for driving the feed belt 22 to move. The feed belt 22 moves upward at an angle, so that the garbage flows to the position of the feed belt 22 during the forward movement of the hull 1 and can be transported to the collection box 23 by the feed belt 22.

[0009] The power assembly 3 includes a rotating rod 31 rotatably connected to the vertical plate 212 and the horizontal plate 211, and a feeding belt 22 connected between the two rotating rods 31. The power assembly 3 also includes a power source 32 mounted on the side wall of the vertical plate 212. The power source 32 is a motor and its output shaft is connected to the rotating shaft 5 on the vertical plate 212, thereby realizing the movement of the feeding belt 22.

[0010] A support plate 4 is also installed on the side wall of the hull 1. The support plate 4 is horizontally positioned and located above the horizontal plate 211. Multiple rotating shafts 5 are rotatably connected to the support plate 4. The lower end of the rotating shafts 5 passes through the support plate 4 and is rotatably connected to the horizontal plate 211. A first element 7 is also installed on the support plate 4. The first element 7 can be a motor or other device. The first element 7 is connected to the rotating shafts 5, thereby driving the rotating shafts 5 to rotate. Actuating plates 6 are evenly fixed on the outer wall of the rotating shafts 5. There is sufficient gap between the actuating plates 6 on two connected rotating shafts 5 to allow garbage to pass through. Under the action of the first element 7, the rotating shafts 5 rotate towards the hull 1, so that the actuating plates 6 can push the water surface towards the hull 1, thereby driving the garbage to flow between the actuating plates 6.

[0011] Reference Figure 2 and Figure 3 The support plate 4 is also equipped with a toggle assembly 8, which is located between the feeding belt 22 and the rotating shaft 5. When the garbage enters between the support plate 4 and the horizontal plate 211 through the toggle piece 6, the toggle assembly 8 can toggle the garbage toward the feeding belt 22, thereby helping the feeding belt 22 to bring the garbage into the collection box 23 and reducing the situation where the garbage is pushed out by the toggle piece 6.

[0012] The support plate 4 has a mounting groove 9. The actuating assembly 8 includes a rotating plate 81 rotatably connected to the mounting groove 9, a second element 82 mounted on the support plate 4 for driving the rotating plate 81 to rotate, and an actuating rod 83 mounted on the rotating plate 81. The second element 82 is a device such as a motor. The rotating plate 81 is rotatably connected to the mounting groove 9 via a round shaft, and one end of the shaft is connected to the second element 82. The rotating plate 81 can be driven to rotate through the second element 82. Described from the perspective of the figure, when the rotating plate 81 rotates, it rotates downwards from the support plate 4, then upwards after passing the feeding belt 22, thereby pushing the waste between the support plate 4 and the horizontal plate 211 towards the feeding belt 22. Multiple feeding belts 22 are spaced apart, and there are gaps between adjacent feeding belts 22. The gaps between the actuating rod 83 and the feeding belts 22 correspond one-to-one. When the rotating plate 81 drives the actuating rod 83 to move, the actuating rod 83 can pass through the gap between the feeding belts 22, thereby helping to move the garbage onto the feeding belts 22.

[0013] Reference Figure 2 and Figure 4 A receiving cavity 11 is provided on the rotating plate 81, and a mounting rod 10 is slidably installed in the receiving cavity 11. The mounting rod 10 slides in a direction perpendicular to the rotation axis of the rotating plate 81. A toggle rod 83 is installed on the mounting rod 10 and is spaced apart along the length of the mounting rod 10. When the mounting rod 10 slides in the receiving cavity 11, it can drive the toggle rod 83 to move closer to or away from the rotation axis of the rotating plate 81. An elastic element 12 is installed in the receiving cavity 11, and a trigger element 13 is installed on the support plate 4. When the toggle rod 83 moves to the gap between the feeding belts 22, the rotating plate 81 continues to rotate. Under the action of the trigger element 13, the mounting rod 10 can be driven to move closer to the rotation axis of the rotating plate 81, so that the toggle rod 83 slides away from the feeding belt 22. At this time, the elastic element 12 is in a compressed state, and the elastic element 12 provides a restoring force for the mounting rod 10. When it loses contact with the trigger element 13, the mounting rod 10 can return to its original position.

[0014] Reference Figure 2 and Figure 3 The rotating plate 81 has clearance grooves 14 at both ends, which are connected to the receiving cavity 11. Both ends of the mounting rod 10 are fixed with abutment rods 15, which are cylindrical and extend through the clearance grooves 14. The trigger element 13 includes a trigger strip 131 fixed to the support plate 4. The trigger strip 131 is inclined and has a certain curvature. When the rotating plate 81 rotates, the abutment rod 15 abuts against the trigger strip 131. When the rotating plate 81 continues to rotate, the abutment rod 15 is pressed against the trigger strip 131, causing it to slide within the clearance grooves 14, thereby driving the mounting rod 10 to slide within the receiving cavity 11.

[0015] Reference Figure 4 and Figure 5 Furthermore, the actuating lever 83 is rotatably connected to the mounting rod 10 via bearings or other means, and an insertion groove 16 is provided on the inner end face of the receiving cavity 11, into which the end of the actuating lever 83 is slidably inserted. When the mounting rod 10 slides, the actuating lever 83 can slide in the insertion groove 16. The elastic element 12 includes springs installed in the receiving cavity 11, and multiple springs are installed. One end of the spring is connected to the inner end face of the receiving cavity 11, and the other end is connected to the mounting rod 10, and the spring is sleeved on the outer wall of the actuating lever 83. When the mounting rod 10 slides toward the rotation axis of the rotating plate 81, the spring is in a compressed state.

[0016] A guide groove 18 is provided on the inner wall of the insertion groove 16, extending along the axis of the insertion groove 16. An inclined groove 19 is also provided on the inner wall of the insertion groove 16, and the inclined groove 19 is connected to the guide groove 18. A protrusion 17 is fixed on the outer wall of the actuating rod 83. When the actuating rod 83 slides into the insertion groove 16, the protrusion 17 slides in the guide groove 18. When the actuating rod 83 continues to slide, the protrusion 17 moves into the inclined groove 19, thereby enabling the actuating rod 83 to rotate. As a result, during the separation of the actuating rod 83 from the feeding belt 22, the actuating rod 83 can rotate on its own axis and slide in the direction away from the feeding belt 22, thus helping the waste to be carried away by the feeding belt 22.

[0017] The implementation principle of a cutter suction dredging vessel according to an embodiment of this application is as follows: During the forward movement of the hull 1, the actuating plate 6 pushes the garbage between the support plate 4 and the horizontal plate 211, and then, under the action of the actuating rod 83, pushes it towards the feeding belt 22, allowing the feeding belt 22 to carry the garbage into the collection frame 23. During the initial separation process from the feeding belt 22, the actuating rod 83 can move in the direction of transporting away from the feeding belt 22 and can rotate, thereby helping to reduce the possibility of the actuating rod 83 lifting up the garbage.

[0018] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
