Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a dredging device for water conservancy projects. Background Technology

[0002] The development trend of water conservancy projects is becoming increasingly apparent, and the status of water conservancy projects in the national economy is becoming increasingly important. Therefore, rural areas have now basically implemented standardized construction of drainage channels in terms of length, width, and height, which greatly facilitates agricultural irrigation.

[0003] As disclosed in the patent announcement CN214090081U, a dredging device for water conservancy projects that can improve dredging efficiency includes a support plate with wheels mounted on the support plate for traveling along both sides of the channel. A push handle is located at the rear of the support plate. A motor and a diesel generator are located at the upper center of the support plate. A drive gear is mounted on the drive shaft of the motor. Vertically downward rotating shafts are mounted on the support plates on both sides of the drive gear. The beneficial effect of this utility model after adopting the above technical solution is that it can improve the efficiency of clearing blockages in the mud.

[0004] While the aforementioned patent can improve the efficiency of clearing blockages, the thickness of sludge accumulated in the drainage channel is not fixed, while the sludge inlet height of the aforementioned device is fixed. If the sludge thickness is low, the high-speed rotating auger will throw the sludge upwards. However, due to the lack of a closed structure at the inlet, the thrown sludge will fall back into the channel from above the open inlet and cannot effectively enter the conveying pipeline, resulting in a significant decrease in dredging efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0023] 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.

[0024] like Figure 1-3 As shown, this utility model provides a technical solution:

[0025] A dredging device for a water conservancy project includes a bottom shell 1 with vertical guide pipes 2 symmetrically fixed on both sides of its bottom end. A transmission box 3 is fixedly installed at the top of the bottom shell 1. A dredging mechanism is provided between the transmission box 3 and the guide pipes 2. The dredging mechanism includes an auger 6 vertically installed inside the two guide pipes 2 and a motor 7 vertically fixed at the middle of the top of the transmission box 3. A drive gear 8 is fixedly installed at the middle of the top of the bottom shell 1 and inside the transmission box 3. The output shaft of the motor 7 is connected to the drive gear. 8. Fixed connection: Driven gears 9, meshing with the driving gear 8, are provided on both sides of the upper end of the bottom shell 1, and are fixedly connected to the auger 6. A V-shaped inlet 17 is opened on the front of the bottom end of the guide pipe 2. A mud discharge pipe 10 is fixedly installed on the upper end of the bottom shell 1, near the outer side of the driven gear 9. The bottom end of the mud discharge pipe 10 penetrates the bottom shell 1 and connects to the upper end of the guide pipe 2. The top end of the mud discharge pipe 10 extends to the outside of the transmission box 3. A lifting frame 4, which is horizontal and... Symmetrically arranged on both sides of the transmission box 3, an angle flipping mechanism is provided between the lifting frame 4 and the transmission box 3. The angle flipping mechanism includes a frame 11 vertically fixed to the middle of the top of the lifting frame 4, and a motor 12 horizontally fixed to the upper part of the left frame 11. The output shaft of the motor 12 is fixedly connected to the left side of the transmission box 3, and the right side of the transmission box 3 is rotatably connected to the right frame 11 through a bearing. A support frame 5 is arranged parallel to the bottom of the lifting frame 4. A bottom groove 15 is horizontally opened at the bottom of the support frame 5. Several rollers 16 arranged side by side are rotatably connected inside the bottom groove 15 through a bearing. A height adjustment mechanism is provided between the support frame 5 and the lifting frame 4. The height adjustment mechanism includes an electric push rod 13 vertically fixed to the middle of the top of the support frame 5, and guide rods 14 symmetrically fixed to the top of both sides of the support frame 5. The output shaft of the electric push rod 13 is fixedly connected to the bottom of the middle of the lifting frame 4. Guide holes that intermittently cooperate with the guide rods 14 are opened on both sides of the lifting frame 4.

[0026] In this embodiment, the working height and tilt angle of the guide pipe 2 are dynamically adjusted by the cooperation of the electric push rod 13 and the motor 12. This solves the problem that the traditional fixed inlet cannot adapt to different sludge thicknesses, and enables the device to automatically optimize the sludge depth according to the actual working conditions, ensuring that sludge of different thicknesses can be effectively captured and transported.

[0027] Furthermore, by integrating the gear pair consisting of the driving gear 8 and the driven gear 9 inside the transmission box 3, a fully enclosed design of the transmission system is achieved, solving the problem that traditional exposed gears are susceptible to erosion by sludge and jamming, thus extending the service life of the device under harsh working conditions.

[0028] Working principle: First, the device is set up on both sides of the top of the drainage ditch, so that the rollers 16 at the bottom of the support frame 5 roll and position themselves along the edge of the ditch top. During dredging, the height of the lifting frame 4 is adjusted by the electric push rod 13, which drives the bottom shell 1 and the guide pipe 2 to descend to the working position. The motor 1 7 drives the drive gear 8 to rotate, and through the meshing of the driven gear 9, the two screw conveyors 6 operate synchronously in the guide pipe 2. The sludge at the bottom of the ditch is sucked in through the V-shaped inlet 17 and then lifted by the screw conveyor 6 to the sludge discharge pipe 10 for discharge. When encountering uneven sludge thickness, the motor 2 12 drives the transmission box 3 to adjust the bottom shell 1 and the guide pipe 2 relative to the frame 11 by 0-30°. For thicker sludge layers, the front end of the V-shaped inlet 17 is pressed down to increase the sludge intake depth. For thinner sections, it is appropriately raised to avoid idling. At this time, the electric push rod 13 synchronously compensates for the height change, enabling the device to achieve efficient dredging operations under different working conditions.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
