Description

Technical Field

[0001] This application relates to the technical field of river dredging equipment, and in particular to a river dredging equipment. Background Art

[0002] Currently, in order to maintain the normal flood control, ecological and other functions of the river, the silt in the river is usually cleaned regularly.

[0003] The existing Chinese utility model patent document with the authorization announcement number CN213114779U discloses an environmental protection engineering river dredging equipment, which includes a dredging mechanism, a filtering mechanism and a drainage mechanism. The dredging mechanism pumps the silt to the filtering mechanism through a sludge pump. The filtering mechanism includes a storage tank. The bottom of the storage tank is provided with through holes and a filter screen is installed at the bottom of the storage tank. The silt is filtered through the filter screen, so that the silt can be collected, and the filtered water is discharged back into the river.

[0004] Although the installation of the filter screen in the storage tank can filter the water of the silt, after using for a period of time, the filter screen is easily blocked by the silt, the filtering effect of the filter screen is greatly reduced, and the filtering effect on the silt is poor. Summary of the Invention

[0005] In order to improve the efficiency of separating silt and water, this application provides a river dredging equipment.

[0006] This application adopts the following technical solutions:

[0007] A river dredging equipment includes a dredging mechanism and a filtering mechanism. The filtering mechanism includes a box body and a separation component arranged on the collection box. The box body includes a silt part and a drainage part. The separation component includes a rotating shaft rotatably connected to the box body, a receiving plate arranged on the outer wall of the rotating shaft, and a power component for driving the rotating shaft to rotate. A plurality of the receiving plates are evenly arranged along the circumferential direction of the rotating shaft, and a plurality of bumps are arranged at intervals on the receiving plate. The dredging mechanism includes a discharge pipe. When the rotating shaft rotates, the receiving plate can pass through the lower end of the discharge pipe, and the bumps are located on the side close to the discharge pipe. The silt water coming out of the discharge pipe can fall onto the receiving plate below the discharge pipe and flow into the drainage part through the receiving plate. The silt can be blocked by the bumps and stay on the receiving plate. When the receiving plate continues to rotate, the silt can fall into the silt part.

[0008] By adopting the above technical solution, a space for receiving sludge is formed between two adjacent receiving plates, and the sludge flows onto the receiving plates. Under the blocking effect of the protrusions, the sludge flows slowly on the receiving plates, while the water flows faster. Therefore, the sludge sucked out by the discharge pipe falls onto the receiving plates, and the water can flow into the drainage part faster. Then the shaft continues to rotate, and the next receiving plate can receive the sludge again, while the original receiving plate is flipped downward, so that the sludge on the receiving plate can fall into the sludge part.

[0009] Optionally, a frame with a hollow interior is provided on the side wall of the rotating shaft, and a mounting groove is provided on the inner wall of the frame, and the receiving plate is slidably connected to the mounting groove, and a first elastic member is installed between the inner wall of one of the mounting grooves and the end of the receiving plate, and a trigger member is provided between the receiving plate and the inner wall of the sludge chamber, when the receiving plate that receives the sludge rotates to face the inner cavity of the sludge chamber, under the action of the trigger member and the first elastic member, the receiving plate can slide back and forth, and the sliding direction of the receiving plate is parallel to the axial direction of the rotating shaft.

[0010] By adopting the above technical solution, the receiving plate is slidably installed in the installation groove, and under the action of the trigger member and the first elastic member, the receiving plate can slide back and forth, so that the sludge on the receiving plate can better fall into the sludge part.

[0011] Optionally, the trigger member includes a trigger rod arranged at one end of the receiving plate away from the elastic member, the trigger rod passes through the side wall of the frame, and an arc groove is provided on the inner wall of the sludge chamber. When the rotating shaft rotates, the trigger rod can move into the arc groove, and protrusions are provided at intervals on the inner wall of the arc groove. Under the action of the first elastic member, the end of the trigger rod can abut against the protrusion.

[0012] By adopting the above technical solution, under the action of the first elastic member, the trigger rod moves with the movement of the frame, the resistance rod moves in the arc groove, and under the action of the protrusion, the receiving plate reciprocates, thereby realizing the reciprocating movement of the receiving plate, which is conducive to the sludge falling into the sludge part.

[0013] Optionally, a connecting rod is rotatably connected to the receiving plate, and the protrusion is installed on the outer wall of the connecting rod and spaced along the outer wall of the connecting rod; a clearance groove for accommodating the connecting rod and the protrusion is opened on the receiving plate; a driving structure is provided on the inner wall of the frame and the sludge chamber, and when the receiving plate slides back and forth, the driving structure can drive the connecting rod to rotate to drive the protrusion to rotate.

[0014] By adopting the above technical solution, the sludge has adhesiveness and is prone to adhere to the bumps. Under the action of the driving structure, when the bumps rotate, the sludge on the surface can be thrown out, which is beneficial for the sludge to fall into the sludge part.

[0015] Optionally, a rotating cylinder is rotatably connected to the frame. One end of the connecting rod penetrates out of the end face of the receiving plate and is slidably inserted into the rotating cylinder. When the rotating cylinder rotates, it can drive the connecting rod to rotate; the driving structure includes a gear coaxially arranged on the outer wall of the rotating cylinder and an arc-shaped tooth arranged on the inner wall of the sludge cavity. When the receiving plate reciprocates, the gear can mesh with the arc-shaped tooth.

[0016] By adopting the above technical solution, when the gear meshes with the arc-shaped tooth, the rotating cylinder can rotate. While the rotating cylinder rotates, it drives the connecting rod to rotate, thereby driving the bumps to rotate.

[0017] Optionally, a slot is opened on the inner wall of the bump. The slot extends along the circumferential direction of the bump. A positioning block is arranged on the outer wall of the connecting rod. The positioning block extends into the slot, and second elastic members are arranged on both sides of the positioning block. One end of the second elastic member away from the positioning block is connected to the inner end face of the slot.

[0018] By adopting the above technical solution, the positioning block extends into the slot and second elastic members are arranged on both sides, enabling the bump to have a certain angle on the connecting rod. When the bump blocks the sludge, the bump can better reduce the flow rate of the sludge, thereby improving the separation effect of the sludge and water.

[0019] Optionally, a water receiving plate is inclined at the upper end of the drainage part. The water on the receiving plate can flow onto the water receiving plate and then flow into the drainage part.

[0020] By adopting the above technical solution, the water receiving plate receives water, which is beneficial for the water to flow into the drainage part through the water receiving plate.

[0021] Optionally, a transition plate is inclined at the upper end of the box body. The sludge flows out from the dredging mechanism and onto the transition plate, and then onto the receiving plate.

[0022] By adopting the above technical solution, under the action of the transition plate, the sludge and water from the discharge pipe can flow onto the receiving plate in a spread-out manner, which helps with the subsequent separation of the sludge and water.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] Silt and water flow onto the receiving plate. When the rotating shaft rotates, the muddy water flows on the receiving plate, and under the action of the bumps, the flow rate of the silt is less than that of the water. When the receiving plate near the drainage part rotates to an inclined state, the water can flow into the drainage part, and when the receiving plate rotates downward, the silt can fall into the silt part.

Detailed Description of the Embodiment

[0033] The following is a further detailed description of the present application in conjunction with the attached Figures 1-7 drawings.

[0034] An embodiment of the present application discloses a river dredging device. Refer to Figure 1, the dredging equipment includes a dredging mechanism 1 and a filtering mechanism 2. The dredging mechanism 1 is used to extract silt, and the filtering mechanism 2 is used to separate silt and water. The dredging mechanism 1 includes a silt suction pump 102 and a discharge pipe 101 connected to the silt suction pump 102. The silt sucked out by the silt suction pump 102 is discharged from the discharge pipe 101.

[0035] Refer to Figure 1 and Figure 2 , the filtering mechanism 2 includes a box body 3 and a separation component 4. The box body 3 is separated by a partition into a silt part 31 and a drainage part 32. The separation component 4 is used to separate silt and water so that water can flow into the drainage part 32 and silt can fall into the silt part 31.

[0036] Refer to Figure 1 and Figure 3 , the separation component 4 includes a rotating shaft 41 rotatably connected to the box body 3, a receiving plate 42 mounted on the side wall of the rotating shaft 41, and a power component 43 for driving the rotating shaft 41 to rotate. The power component 43 is a motor. The rotating shaft 41 is located above the silt part 31, and three receiving plates 42 are evenly arranged along the circumference of the rotating shaft 41. A space for receiving silt can be formed between two adjacent receiving plates 42. When the receiving plate 42 rotates, it can move to the lower part of the outlet of the discharge pipe 101, and the silt coming out of the discharge pipe 101 can fall onto the receiving plate 42. A plurality of bumps 5 are also spacedly installed on the surface of the receiving plate 42. When the silt flows onto the receiving plate 42, the rotating shaft 41 continues to rotate, causing the silt to flow on the receiving plate 42. And under the blocking action of the bumps 5, the flow rate of the silt is less than that of the water, and the water can first flow through the receiving plate 42 into the drainage part 32. When the rotating shaft 41 continues to rotate and the receiving plate 42 with silt rotates downward, the silt can fall into the silt part 31.

[0037] Refer to Figure 2 and Figure 4 , a frame 6 is fixed on the outer wall of the rotating shaft 41. The frame 6 is a hollow structure inside, and mounting grooves 7 are symmetrically opened on the inner walls at both ends of the frame 6. The two ends of the receiving plate 42 are slidably inserted into the mounting grooves 7, so that the receiving plate 42 can slide along the direction parallel to the axis of the rotating shaft 41. A first elastic member 8 is installed in one of the mounting grooves 7. The first elastic member 8 is connected between the inner wall of the mounting groove 7 and the end face of the receiving plate 42. The first elastic member 8 is a spring, and a plurality of springs are provided. A trigger member 9 is also installed between the receiving plate 42 and the silt part 31. When the receiving plate 42 rotates downward, the trigger member 9 can drive the receiving plate 42 to slide reciprocally, making the silt on the receiving plate 42 easier to fall into the silt part 31.

[0038] Refer to Figure 4 and Figure 5The trigger member 9 includes a trigger rod 91 fixed to one end of the receiving plate 42 away from the first elastic member 8, and the trigger rod 91 is inserted from the side wall of the frame 6. A circular arc groove 10 is provided on the side wall of the mud portion 31, and when the rotating shaft 41 rotates, the trigger rod 91 can move into the circular arc groove 10. A plurality of convex points 11 are fixed at intervals on the inner wall of the circular arc groove 10. Under the action of the first elastic member 8, the trigger rod 91 can abut against the inner wall of the circular arc groove 10. When it moves to the convex point 11, the trigger rod 91 is pressed by the convex point 11, so that the first elastic member 8 is compressed. When the trigger rod 91 and the convex point 11 are out of contact, the first elastic member 8 returns to drive the receiving plate 42 to slide, so that under the action of the convex point 11 and the trigger rod 91, the receiving plate 42 reciprocates, which is conducive to the mud on the receiving plate 42 falling into the mud portion 31. In order to facilitate the sludge from the discharge pipe 101 to flow onto the receiving plate 42 , a transition plate 20 is fixed to the box body 3 , and the sludge from the discharge pipe 101 first flows onto the transition plate 20 and then flows onto the receiving plate 42 .

[0039] Reference Figure 4 and Figure 6 , a connecting rod 12 is rotatably mounted on the receiving plate 42, and a protrusion 5 is mounted on the outer wall of the connecting rod 12. The protrusion 5 is a structure that is large in the middle and small at both ends, and multiple protrusions 5 are mounted on each connecting rod 12. A clearance groove 13 is provided on the receiving plate 42, and the connecting rod 12 passes through the clearance groove 13. The clearance groove 13 runs through both sides of the receiving plate 42, and the clearance groove 13 is adapted to the structure of the protrusion 5. In this embodiment, three connecting rods 12 are installed, and the axial directions of the connecting rod 12 and the rotating shaft 41 are parallel. Among them, the protrusion 5 on the connecting rod 12 corresponds to the gap formed between the two protrusions 5 on the other connecting rods 12, so that after the sludge passes through the gap between the two protrusions 5, it can be blocked by the protrusion 5 behind, and diverted here, further improving the retention effect of the sludge.

[0040] A driving structure is also installed between the frame 6 and the sludge part 31. When the material receiving space formed by the two receiving plates 42 rotates downward, the driving structure can drive the connecting rod 12 to rotate. The rotation of the connecting rod 12 drives the protrusion 5 to rotate, which helps the protrusion 5 to throw off the sludge on the surface.

[0041] Reference Figure 4 and Figure 6 A rotating cylinder 15 is rotatably connected to one end surface of the frame 6, and the rotating cylinder 15 passes through the installation groove 7. The rotating cylinder 15 is an internal hollow structure, and the cavity of the rotating cylinder 15 is a square structure. One end of the connecting rod 12 is also set to a square structure, and the end of the connecting rod 12 is slidably inserted in the rotating cylinder 15, so that when the receiving plate 42 slides in the installation groove 7, the connecting rod 12 can slide in the rotating cylinder 15, and when the rotating cylinder 15 rotates, it can drive the connecting rod 12 to rotate.

[0042] Refer to Figure 2 and Figure 6 Figure 6

[0043] Refer to Figure 3 and Figure 7 Figure 7

[0044] Refer to Figure 3 Figure 3

[0045] Further, refer to Figure 2 Figure 2

[0046] The implementation principle of a river dredging device in an embodiment of the present application is as follows: The discharge pipe 101 sends the silt to the transition plate 20 and flows onto the receiving plate 42 through the transition plate 20. When the rotating shaft 41 continues to rotate, the silt and water flow in the direction of the drainage part 32. Under the action of the convex block 5, the flow rate of the silt is slower and the flow rate of the water is faster, so that the water flows to the drainage part 32, and the silt drops onto the silt part 31, and the water in the silt part 31 can flow into the drainage tank 22.

[0047] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
