[0029] Embodiment: This embodiment aims to provide a dredging device for replacement filling construction, the main function of which is to greatly improve the service life of the mud conveying pipeline, and the length of the mud conveying pipeline penetrating into the mud can be adjusted without human intervention.
[0030] Reference Figure 1 , Figure 2 and Figure 3, including: a positioning plate 1, a supporting plate 2, a lifting and pressing plate 4, a mud conveying pipe 5 and a telescopic diagonal bracing arm 7. The positioning plate 1 is fixed to the hard ground surface near the silt area by ground nails 8. If necessary, a counterweight can be placed in the idle area of the upper plate surface of the positioning plate 1. The supporting plate 2 is arranged directly above the positioning plate 1, and the supporting plate 2 is kept parallel to the positioning plate 1. Two guide columns 3 are arranged on the right between the supporting plate 2 and the positioning plate 1. The two guide columns 3 are arranged in parallel, one in front and one behind. The upper end of the guide column 3 is welded and fixed to the lower plate surface of the supporting plate 2, and the lower end is welded and fixed to the upper plate surface of the positioning plate 1. The guide column 3 is used to stably support the supporting plate 2.
[0031] Reference Figure 1 , Figure 2 and Figure 3 The lifting plate 4 is horizontally arranged between the support plate 2 and the positioning plate 1, and a pair of the lifting plates 4 are provided corresponding to the guide column 3. The two lifting plates 4 are also arranged one after the other. The right end of the lifting plate 4 is sleeved on the outside of the corresponding guide column 3, so that the lifting plate 4 can be displaced along the axial direction of the guide column 3 through the lifting mechanism. Specifically, the lifting mechanism includes: a lifting motor 9 and a threaded column 10. The lifting motor 9 is fixed to the upper plate surface of the support plate 2. The threaded column 10 is located between the support plate 2 and the positioning plate 1. The threaded column 10 is provided with a pair of corresponding guide columns 3. The two threaded columns 10 are also arranged one after the other. The upper end of the front stud After passing through the support plate 2, it is connected to the lifting motor 9 for transmission. The lower end is rotatably arranged inside the positioning plate 1 through a plane bearing. The upper and lower ends of the rear stud column are rotatably arranged in the corresponding support plate 2 and positioning plate 1 through plane bearings. The use of plane bearings can ensure that the threaded column 10 is not affected by the axial load and rotates stably. The plane bearing is not shown in the figure. The upper ends of the two threaded columns 10 can be driven by a pulley or a sprocket to achieve synchronous rotation. The middle threads of the two lifting and pressing plates 4 are sleeved on the outside of the corresponding threaded columns 10. The lifting and pressing plates 4 are driven to move up and down along the axial direction of the guide column 3 through the rotation of the threaded column 10.
[0032] Reference Figure 2 , Figure 3 and Figure 4 The mud delivery pipe 5 is vertically arranged between the supporting plate 2 and the positioning plate 1, and a swing interval is reserved between the upper end and the lower end of the mud delivery pipe 5 and the corresponding supporting plate 2 and the positioning plate 1, respectively, so as to avoid interference with the swing of the mud delivery pipe 5. At the same time, the mud delivery pipe 5 is between the two lifting and pressing plates 4 and is close to the left, so that the upper outer wall of the mud delivery pipe 5 is hinged to the inner side of the left end of the two lifting and pressing plates 4 at the same time. A mud outlet nozzle 6 is convexly arranged on the right side of the upper outer wall of the mud delivery pipe 5, and the direction of the mud outlet nozzle 6 is consistent with the length direction of the lifting and pressing plate 4. A mud inlet is arranged at the lower end of the mud delivery pipe 5; a rotating shaft 12 is arranged inside the mud delivery pipe 5 for rotation, and a spiral blade 13 is arranged on the outer side of the rotating shaft 12. The upper end of the rotating shaft 12 is transmission-connected to a driving motor 14, and the driving motor 14 is fixed to the upper end of the mud delivery pipe 5.
[0033] Reference Figure 1 and Figure 3 The telescopic diagonal brace arm 7 is tilted and placed between the support plate 2 and the positioning plate 1. Specifically, the telescopic diagonal brace arm 7 is a cylinder. The lower end of the telescopic diagonal brace arm 7 is hinged to the right position of the center of the upper plate surface of the positioning plate 1, and the upper end of the telescopic diagonal brace arm 7 is hinged to the middle part of the mud pipe 5. During the period when the lifting plate 4 moves downward along the axial direction of the guide column 3, the lower end of the mud pipe 5 is swung toward the mud area under the supporting action of the telescopic diagonal brace arm 7. Then, when the lower end of the mud pipe 5 is tilted to a certain extent, the height of the lower end of the mud pipe 5 can be lowered by shortening the rod of the cylinder, so that the lower end of the mud pipe 5 can enter the mud. Among them, the state of the telescopic diagonal brace arm 7 accompanying the mud pipe 5 in the vertical state is the longest state to ensure the length of the subsequent mud pipe 5 penetrating into the mud.
[0034] In this embodiment, a hinge shaft 11 is provided on the outer wall of the mud conveying pipe 5 corresponding to the inner side of the left end of the lifting plate 4 and the upper end of the telescopic diagonal bracing arm 7 to ensure the overall linkage of the device.
[0035] In this embodiment, the lower end of the rotating shaft 12 protrudes outward from the mud conveying pipe 5, and a mud pounding ball head 15 is provided at the lower end of the rotating shaft 12. A convex column is provided on the surface of the mud pounding ball head 15. The mud lumps can be broken up in advance through the mud pounding ball head 15, which can improve the working efficiency of the mud conveying pipe 5.
[0036] During actual use, the device is fixed above the hard stratum near the silt area, and the mud pipe 5 is brought close to the silt area. Then the lifting plate 4 is controlled to descend, and the mud pipe 5 is tilted under the supporting action of the telescopic diagonal support arm 7, that is, the lower end of the mud pipe 5 is swung toward the silt area as the lifting plate 4 descends. At the same time, the mud outlet 6 on the upper right side of the mud pipe 5 swings toward the area receiving the silt. When the mud pipe 5 reaches a certain inclination angle, the height of the lower end of the mud pipe 5 can be adjusted by shortening the telescopic diagonal support arm 7 so that the lower end of the mud pipe 5 enters the silt. As the height of the silt gradually decreases, the height of the lower end of the mud pipe 5 can be adjusted accordingly, which has great flexibility.
[0037] The dredging device provided in this embodiment abandons the traditional method of using a hose to transport sludge and instead uses a hard pipe, thereby avoiding the risk of wear and even rupture of the sludge conveying pipeline, greatly improving the service life of the sludge conveying pipeline, and the utility model has high flexibility, and the length of the sludge conveying pipeline that penetrates into the sludge can be adjusted without human intervention. It is easy to operate and has excellent use effect.
[0038] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.
[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model are within the scope of protection of the pending claims of the present utility model.
