Description

Technical Field

[0001] This utility model belongs to the field of river dredging technology, specifically relating to a dredging device used in river management projects. Background Technology

[0002] River dredging is a crucial part of maintaining water quality and protecting the health of river ecosystems. Inadequate dredging can lead to reduced flood control capacity, decreased biodiversity, deterioration of water quality, and impeded water flow, ultimately resulting in a decline in the overall ecological quality of the river.

[0003] A river dredging device, with publication number CN222332806U, belongs to the field of river cleaning technology. It includes a vehicle body; a sludge dewatering component mounted on the vehicle body, with its output end connected to a discharge pipe; and a sludge pumping component connected to the input end of the sludge dewatering component. The sludge dewatering component has a dewatering port at its bottom, and a water collection tank below the dewatering port. The water collection tank is connected to a high-pressure water pump, which is connected to at least one set of high-pressure nozzles. The high-pressure nozzles spray towards the suction end of the sludge pumping component. Through the cooperation of the sludge pumping component, sludge dewatering component, water collection tank, high-pressure water pump, and high-pressure nozzles, water circulation is achieved, allowing the separated water to be reused, saving significant water resource costs and avoiding water waste.

[0004] Existing river dredging equipment has the following main drawbacks:

[0005] Existing silt removal equipment mainly sucks silt out of the river. During the silt suction process, the area that the silt suction inlet can contact with the silt is small, which makes the silt removal efficiency low. Utility Model Content

[0006] The purpose of this utility model is to provide a dredging device for river management projects, including an operating platform. A driving component is fixedly connected to the upper end of the operating platform, a driven component is rotatably connected to the operating platform, a dredging mechanism is fixedly connected to the operating platform, a mud pump is fixedly connected to the operating platform, and connecting frames are fixedly connected to both sides of the lower end of the operating platform.

[0007] The dredging mechanism includes:

[0008] A collecting component, wherein a squeezing component is rotatably connected within the collecting component, and the collecting component is fixedly connected to a connecting frame.

[0009] Furthermore, the collection component includes:

[0010] The collection chamber is fixedly connected to the connecting frame. A sludge removal shaft is rotatably connected inside the collection chamber. Several push plates are fixedly connected to the sludge removal shaft. Connecting plates are provided at both ends of the push plates. A mud outlet is opened at the upper end of the collection chamber. Both ends of the sludge removal shaft are fixedly connected to a synchronous wheel.

[0011] Furthermore, the extrusion assembly includes:

[0012] Several lead screws are provided, with both ends of the lead screws rotatably connected to a connecting plate. Each end of the lead screws is fixedly connected to a gear, and each end of the lead screws is fixedly connected to one end of a torsion spring. The other end of the torsion spring is fixedly connected to the connecting plate. Two extrusion plates are slidably connected to the lead screws. An arc-shaped toothed ring is fixedly connected inside the collecting cavity, and the gear meshes with the arc-shaped toothed ring.

[0013] Furthermore, the driven component includes:

[0014] Two primary driven shafts are rotatably connected to two connecting frames respectively. Both ends of each primary driven shaft are fixedly connected to a second synchronous pulley. The second synchronous pulley and the first synchronous pulley are driven by a synchronous belt. Both ends of each primary driven shaft are fixedly connected to a track assembly. A first bevel gear is fixedly connected to each primary driven shaft. A secondary driven shaft is rotatably connected to the operating platform. A first bevel gear is fixedly connected to the lower end of the secondary driven shaft. The two first bevel gears mesh. A second bevel gear is fixedly connected to the upper end of the secondary driven shaft.

[0015] Furthermore, the driving component includes:

[0016] The motor is fixedly connected to the operating platform. The output end of the motor is fixedly connected to one end of the drive shaft. The drive shaft is rotatably connected to the upper end of the operating platform. A second bevel gear is fixedly connected to the drive shaft, and the two bevel gears mesh.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] As the pusher plate rotates upwards from the bottom, gear one meshes with the arc-shaped toothed ring. During this process, the rotation of gear one drives the lead screw to rotate, causing the two extrusion plates to move closer together and squeeze the mud between the two pusher plates towards the center. The mud pump then pumps the mud from the center out of the mud outlet. When gear one disengages from the arc-shaped toothed ring, the lead screw rotates in the opposite direction under the action of the torsion spring, and the extrusion plates return to their original positions. The extrusion plates concentrate the mud below the mud outlet so that the mud pump can remove the sludge, thus making the sludge removal more efficient. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and 4As shown, a dredging device for river management projects includes an operating platform 1. A drive assembly 2 is fixedly connected to the upper end of the operating platform 1. A driven assembly 3 is rotatably connected to the operating platform 1. A dredging mechanism 4 is fixedly connected to the operating platform 1. A mud pump 5 is fixedly connected to the operating platform 1. Connecting frames 11 are fixedly connected to both sides of the lower end of the operating platform 1.

[0033] The dredging mechanism 4 includes:

[0034] A collection component 41 is rotatably connected to a squeezing component 42, and the collection component 41 is fixedly connected to a connecting frame 11.

[0035] During dredging, the drive component 2 is activated, causing the driven component 3 to rotate, which in turn causes the collection component 41 to rotate. At the same time, the operating platform 1 moves forward, and the squeezing component 42 rotates as the collection component 41 rotates.

[0036] Reference Figure 5 As shown, the collection component 41 includes:

[0037] A collection chamber 411 is fixedly connected to a connecting frame 11. A sludge removal shaft 412 is rotatably connected inside the collection chamber 411. Several push plates 413 are fixedly connected to the sludge removal shaft 412. Connecting plates 414 are provided at both ends of the push plates 413. A mud outlet 4111 is opened at the upper end of the collection chamber 411. Both ends of the sludge removal shaft 412 are fixedly connected to a synchronous pulley 415.

[0038] When the driven component 3 rotates, it drives the sludge removal shaft 412 to rotate, which in turn drives the push plate 413 and the connecting plate 414 to rotate in the collection chamber 411. At the same time, the synchronous wheel 415 also rotates. When one of the push plates 413 rotates to the lower end, during the continued rotation, the push plate 413 pushes the mud into the collection chamber 411. During the continued rotation, the push plate 413 pushes the mud to rotate in the collection chamber 411.

[0039] Reference Figure 6 As shown, the extrusion assembly 42 includes:

[0040] Several lead screws 421 are rotatably connected at both ends to a connecting plate 414. Gears 422 are fixedly connected to both ends of each lead screw 421. One end of a torsion spring 423 is fixedly connected to both ends of each lead screw 421. The other end of the torsion spring 423 is fixedly connected to the connecting plate 414. Two extrusion plates 424 are slidably connected to each lead screw 421. An arc-shaped toothed ring 425 is fixedly connected inside the collecting cavity 411. Gears 422 mesh with the arc-shaped toothed ring 425.

[0041] During the upward rotation of the push plate 413 from the bottom, the gear 422 meshes with the arc-shaped toothed ring 425. During this process, the rotation of the gear 422 drives the lead screw 421 to rotate. Through the lead screw 421, the two extrusion plates 424 move closer to each other, squeezing the mud between the two push plates 413 towards the middle. The mud pump 5 then pumps the mud from the outlet 4111. When the gear 422 disengages from the arc-shaped toothed ring 425, the lead screw 421 rotates in the opposite direction under the action of the torsion spring 423, and the extrusion plate 424 returns to its original position.

[0042] Reference Figure 2-3 As shown, the driven component 3 includes:

[0043] Two primary driven shafts 31 are rotatably connected to two connecting frames 11 respectively. Both ends of each primary driven shaft 31 are fixedly connected to a second synchronous pulley 32. The second synchronous pulley 32 and the first synchronous pulley 415 are driven by a synchronous belt 33. Both ends of each primary driven shaft 31 are fixedly connected to a track assembly 34. A first bevel gear 422 is fixedly connected to each primary driven shaft 31. A secondary driven shaft 35 is rotatably connected to the operating platform 1. A first bevel gear 422 is fixedly connected to the lower end of the secondary driven shaft 35. The two first bevel gears 422 mesh. A second bevel gear 36 is fixedly connected to the upper end of the secondary driven shaft 35.

[0044] The rotation of drive assembly 2 drives bevel gear 36 to rotate, which in turn drives secondary driven shaft 35 to rotate. The meshing of two bevel gears 422 drives primary driven shaft 31 to rotate, which in turn drives synchronous pulley 32 to rotate. Through the transmission of synchronous belt 33, synchronous pulley 415 is driven to rotate.

[0045] The driving component 2 includes:

[0046] Motor 21 is fixedly connected to the operating platform 1. The output end of the motor 21 is fixedly connected to one end of the drive shaft 22. The drive shaft 22 is rotatably connected to the upper end of the operating platform 1. A bevel gear 36 is fixedly connected to the drive shaft 22, and the two bevel gears 36 mesh.

[0047] The rotation of motor 21 drives the rotation of drive shaft 22, which is fixedly connected to it, and in turn drives the rotation of bevel gear 36, which is fixedly connected to drive shaft 22.
