A dredging and reclamation device

Abstract

This invention discloses a dredging and reclamation device, relating to the technical field of reclamation devices. It includes a suction pipe, a conveying pipe at the discharge end of the suction pipe, a corrugated pipe connected to the discharge end of the conveying pipe, a spraying pipe connected to the discharge end of the corrugated pipe, and a height adjustment mechanism below the spraying pipe, with an angle adjustment mechanism installed below the height adjustment mechanism. The height adjustment mechanism involves rotating a handwheel, which drives a driving bevel gear. The meshing rotation of the driving and driven bevel gears drives a rotating shaft and a lead screw. The cooperation between the lead screw and the screw hole causes a second support rod to change the height of the spraying pipe. The angle adjustment mechanism uses a reduction motor to drive a full gear, which in turn drives a half gear. The connecting column causes a third and second support rod to rotate synchronously with the half gear, thereby changing the orientation of the spraying pipe.

Description

Technical Field

[0001] This invention relates to the field of dredging and reclamation equipment, and more particularly to a dredging and reclamation equipment. Background Technology

[0002] The dredging and filling device used for river management is an important piece of equipment in dredging projects. It often uses dredging machinery to excavate and remove soil underwater, and then uses mud pumps to transport mud to fill pits, raise the ground, or build dams. It is also a method of dumping soil in dredging projects.

[0003] Currently, most of the dredging and reclamation equipment built using dredgers is made of large vessels and is suitable for large-scale projects. However, it is not suitable for small-scale river dredging. In addition, the dredging and reclamation pipes built by small projects often use steel pipes to support the nozzles, which makes it difficult to control the direction and angle of the dredging and reclamation, thus affecting the smooth progress of the construction. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dredging and reclamation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dredging and reclamation device includes a suction pipe, a conveying pipe at the discharge end of the suction pipe, a corrugated pipe at the discharge end of the conveying pipe, a spraying pipe at the discharge end of the corrugated pipe, a height adjustment mechanism below the spraying pipe, and an angle adjustment mechanism below the height adjustment mechanism.

[0007] Preferably, the height adjustment mechanism includes a second bracket, with connecting members symmetrically fixed below the second bracket. A second support rod is rotatably connected to the lower end of the connecting member. A third support rod is slidably connected to the outside of the second support rod. A rotating rod is rotatably connected to one side of the third support rod. A driving bevel gear is fixed to one end of the rotating rod. A driven bevel gear is meshed above the driving bevel gear. A rotating shaft is fixed through the middle of the driven bevel gear. The rotating shaft is rotatably connected to the third support rod, and a lead screw is fixed to the upper end of the rotating shaft. A screw hole is provided below the second support rod, and the lead screw is threaded into the screw hole.

[0008] Preferably, the angle adjustment mechanism includes a half gear, a reduction motor, and a limiting seat. The half gear is fixedly connected to the third support rod via a connecting column. The output end of the reduction motor is connected to a full gear, which meshes with the half gear. A slider is fixed below the half gear, and the slider is slidably connected to the limiting seat.

[0009] Preferably, a first bracket is fixed below the conveying pipe, a first support rod is fixed below the first bracket, a first base is fixed at the lower end of the first support rod, and a second base is fixed below the limiting seat and the reduction motor.

[0010] Preferably, the rotating rod and the rotating shaft are rotatably connected to the third support rod via bearings, and a handwheel is fixed to the other end of the rotating rod.

[0011] Preferably, a locking mechanism is provided between the rotating rod and the third support rod. The locking mechanism includes a hollow column and a fixed ring. The hollow column and the fixed ring are both fixedly connected to the third support rod. An elastic plate is fixed to one end of the fixed ring, and a clamp is fixedly connected to one end of the elastic plate. A rotating sleeve is threaded to one end of the hollow column, and a rotating handle is fixed to one end of the rotating sleeve.

[0012] Preferably, one end of the clamp is provided with a first inclined surface, and one end of the rotating sleeve is provided with a second inclined surface.

[0013] Preferably, both the discharge end of the suction pipe and the inlet end of the conveying pipe are fixed with flanges, and the two flanges are fixedly connected by fastening bolts.

[0014] Preferably, an anti-slip pad is fixed to one end of the hollow column.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Equipped with a height adjustment mechanism, rotating the handwheel drives the driving bevel gear to rotate. Under the meshing rotation of the driving bevel gear and the driven bevel gear, the rotating shaft and the lead screw are driven to rotate. Under the cooperation of the lead screw and the screw hole, the second support rod drives the mud spraying pipe to change the height, thereby adjusting the height of the sprayed mud.

[0017] 2. An angle adjustment mechanism is provided. The full gear is driven to rotate by the reduction motor, and the full gear drives the half gear to rotate. Under the connection of the connecting column, the third support rod and the second support rod rotate synchronously with the half gear, thereby changing the orientation of the mud spraying pipe.

[0018] 3. Equipped with a locking mechanism, when the handle is rotated forward, the rotating sleeve gradually moves outward from the hollow column. Due to the cooperation of the first and second inclined surfaces, the elastic force of the elastic plate gradually loosens the clamp and allows the handwheel to be rotated. When the handle is rotated in the opposite direction, the rotating sleeve gradually moves inward from the hollow column. Due to the cooperation of the first and second inclined surfaces, the clamp gradually tightens around the rotating rod. The elastic plate deforms under force, and the clamp temporarily secures the rotating rod, preventing the drive bevel gear from rotating, thus keeping the mud spraying pipe at a stable height.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-6A dredging and reclamation device includes a suction pipe 1, a conveying pipe 2 at the discharge end of the suction pipe 1, and flanges 3 fixed to both the discharge end of the suction pipe 1 and the inlet end of the conveying pipe 2. The two flanges 3 are fixedly connected by fastening bolts 4, thus securing the conveying pipe 2 and the suction pipe 1. A corrugated pipe 5 is connected to the discharge end of the conveying pipe 2, and a spraying pipe 6 is connected to the discharge end of the corrugated pipe 5. A height adjustment mechanism is located below the spraying pipe 6. The height adjustment mechanism includes a second support 10, with connecting parts 11 symmetrically fixed below the second support 10. A second support rod 12 is rotatably connected to the lower end of the connecting parts 11, and a third support rod 13 is slidably connected to the outside of the second support rod 12. A rotating rod 14 is rotatably connected to one side of the third support rod 13. One end of the rod is fixed with a driving bevel gear 15, and a driven bevel gear 17 is meshed above the driving bevel gear 15. A rotating shaft 18 is fixed through the middle of the driven bevel gear 17. The rotating shaft 18 is rotatably connected to the third support rod 13, and a lead screw 19 is fixed at the upper end of the rotating shaft 18. A screw hole 20 is opened below the second support rod 12, and the lead screw 19 is threadedly connected to the screw hole 20. The rotating rod 14 and the rotating shaft 18 are both rotatably connected to the third support rod 13 through bearings. A handwheel 16 is fixed at the other end of the rotating rod 14. Rotating the handwheel 16 causes the rotating rod 14 to drive the driving bevel gear 15 to rotate. Under the meshing rotation of the driving bevel gear 15 and the driven bevel gear 17, the rotating shaft 18 and the lead screw 19 are driven to rotate. Under the cooperation of the lead screw 19 and the screw hole 20, the second support rod 12 drives the mud spraying pipe 6 to change its height.

[0028] A first bracket 7 is fixed below the conveying pipe 2, a first support rod 8 is fixed below the first bracket 7, and a first base 9 is fixed to the lower end of the first support rod 8. The first bracket 7 is fixed below the conveying pipe 2, and the conveying pipe 2 is supported by the first bracket 7, the first support rod 8, and the first base 9. A second base 34 is fixed below the limiting seat 32 and the reduction motor 31. The first base 9 and the second base 34 can be fixed to the ground using tools such as anchor bolts. An angle adjustment mechanism is installed below the height adjustment mechanism. The angle adjustment mechanism includes a half gear 29, a reduction motor 31, and a limiting seat 32. The half gear 29 is connected to the connecting column 2. 8 is fixedly connected to the third support rod 13. The output end of the reduction motor 31 is connected to the full gear 30, which meshes with the half gear 29. A slider 33 is fixed below the half gear 29 and is slidably connected to the limit seat 32. When the reduction motor 31 is started, the reduction motor 31 drives the full gear 30 to rotate, and the full gear 30 drives the half gear 29 to rotate. During this period, the slider 33 slides in the limit seat 32, which limits the movement trajectory of the half gear 29. Under the connection of the connecting column 28, the third support rod 13 and the second support rod 12 rotate synchronously with the half gear 29, thereby changing the orientation of the mud spraying pipe 6.

[0029] A locking mechanism is provided between the rotating rod 14 and the third support rod 13. The locking mechanism includes a hollow column 21 and a fixing ring 22. Both the hollow column 21 and the fixing ring 22 are fixedly connected to the third support rod 13. An elastic plate 23 is fixed to one end of the fixing ring 22, and a clamp 24 is fixedly connected to one end of the elastic plate 23. A rotating sleeve 25 is threaded to one end of the hollow column 21, and a rotating handle 26 is fixed to one end of the rotating sleeve 25. A first inclined surface is provided at one end of the clamp 24, and a second inclined surface is provided at one end of the rotating sleeve 25. When the rotating handle 26 is rotated in the forward direction, the rotating sleeve 25 gradually rotates outward from the hollow column 21. As the part moves, due to the cooperation of the first and second inclined surfaces, under the elastic force of the elastic plate 23, the clamp 24 can gradually loosen the rotating rod 14, allowing the handwheel 16 to be rotated. When the handle 26 is rotated in the opposite direction, the rotating sleeve 25 gradually rotates and moves into the hollow column 21. Due to the cooperation of the first and second inclined surfaces, the clamp 24 gradually tightens the rotating rod 14, and the elastic plate 23 deforms under force. The clamp 24 can temporarily fasten the rotating rod 14, preventing the active bevel gear 15 from rotating, thereby keeping the mud spraying pipe 6 at a stable height position.

[0030] One end of the hollow column 21 is fixed with an anti-slip pad 27. When the handle 26 is rotated in the opposite direction, the rotating sleeve 25 gradually rotates and moves into the hollow column 21 until the handle 26 fully contacts the anti-slip pad 27, so as to prevent the anti-slip pad 27 from rotating accidentally without external force intervention.

[0031] In this invention, the two flanges 3 are first connected by fastening bolts 4 to fix the conveying pipe 2 and the suction pipe 1. Then, the first bracket 7 is fixed below the conveying pipe 2. The conveying pipe 2 is supported by the first bracket 7, the first support rod 8 and the first base 9. Then, the second bracket 10 in the height adjustment mechanism is fixed below the sludge spraying pipe 6 to complete the installation of the height adjustment mechanism and the angle adjustment mechanism. The first base 9 and the second base 34 can be fixed to the ground by tools such as anchor bolts.

[0032] When the height of the sludge spray pipe 6 needs to be adjusted, first rotate the handle 26 clockwise. The rotating sleeve 25 gradually rotates and moves outward from the hollow column 21. Due to the cooperation of the first and second inclined surfaces, under the elastic force of the elastic plate 23, the clamp 24 can gradually loosen the rotating rod 14. Then, the handwheel 16 can be rotated, and the rotating rod 14 drives the driving bevel gear 15 to rotate. Under the meshing rotation of the driving bevel gear 15 and the driven bevel gear 17, the rotating shaft 18 and the lead screw 19 are driven to rotate. With the cooperation of the screw hole 20, the second support rod 12 drives the mud spraying pipe 6 to change in height. Finally, the handle 26 is rotated in the opposite direction, causing the rotating sleeve 25 to gradually rotate and move into the hollow column 21. Due to the cooperation of the first inclined part and the second inclined part, the clamp 24 gradually clamps the rotating rod 14. The elastic plate 23 is deformed by force. The clamp 24 can temporarily fasten the rotating rod 14 to prevent the active bevel gear 15 from rotating, thereby keeping the mud spraying pipe 6 at a stable height position.

[0033] If it is necessary to adjust the orientation angle of the mud spraying pipe 6, start the reduction motor 31. The reduction motor 31 drives the full gear 30 to rotate, and the full gear 30 drives the half gear 29 to rotate. During this period, the slider 33 slides in the limit seat 32, which limits the movement trajectory of the half gear 29. Under the connection of the connecting column 28, the third support rod 13 and the second support rod 12 rotate synchronously with the half gear 29, thereby changing the orientation of the mud spraying pipe 6.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
