Description

Technical Field

[0001] This utility model relates to the field of silt prevention and dredging technology, and in particular to special machinery for silt prevention and dredging of water conservancy channels. Background Technology

[0002] Irrigation canals are man-made waterways primarily used for irrigation and also play a role in flood control and drainage systems. The siltation and cleaning process requires specialized machinery designed to address the problem of siltation in irrigation canals. These machines are highly efficient at dredging, reaching deep into the bottom and slopes of the canals to excavate and remove accumulated silt and debris. For example, cutter suction dredgers use cutters to break up underwater silt and then powerful pumps to remove it, significantly improving dredging efficiency. In terms of silt prevention, some machines can prevent sediment deposition by agitating the water and installing debris barriers. For instance, installing a bar screen at the canal inlet can block large floating objects and some silt from entering the canal, achieving initial silt prevention. However, if the machinery is not properly secured during siltation, it can slip, reducing the effectiveness of the silt removal process.

[0003] The existing fixing mechanism mainly serves to stabilize the equipment. Structurally, it typically includes clips, support components, and connecting components. The support components generally use high-strength metal brackets, the shape and size of which are designed according to the type of equipment and the actual conditions of the channel. In the fixing mechanism of large channel dredging vessels, there are multiple robust hydraulic support legs. During operation, these support legs extend through the hydraulic system and firmly anchor themselves into the banks or bottom of the channel, providing a stable working platform for the dredging vessel and preventing the equipment from shifting due to water flow impact and its own vibration during dredging. The connecting components are used to tightly connect the fixing mechanism to the main body of the dredging equipment. These can be metal connectors welded to the equipment chassis or detachable bolt connections, ensuring a firm and reliable connection between the fixing mechanism and the main body, enabling effective power transmission, and preventing loosening during operation. However, this fixing method requires tools to tighten the bolts, which consumes a lot of dredging time and manpower, and cannot be automated. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special machine for preventing and clearing silt from water conservancy channels. It aims to improve the problem that the existing fixing method requires tools to tighten the bolts during fixing, which consumes a lot of silt removal time and manpower, and cannot be automatically fixed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a special machine for silt prevention and dredging of water conservancy channels, including a support plate. Multiple motors are fixedly connected to the left and right sides of the support plate near the center. A rotating rod is fixedly connected to the output end of each motor. A threaded rod is fixedly connected to the bottom of the rotating rod. A threaded sleeve is threadedly connected to the bottom of the threaded rod. A threaded hole is provided at the top of the threaded sleeve. A square locking block is fixedly connected to the outer wall of the threaded sleeve. Fixing plates are fixedly connected to the front and rear sides of the square locking block. Multiple locking posts are fixedly connected to the rear side of each fixing plate. A square locking block is fixedly connected to the rear side of each locking post. A sliding rod is slidably connected inside the square locking block.

A collection box is fixedly connected to the bottom of the positioning post, and the top of the collection box is slidably connected to the bottom of the support plate.

[0008] As a further description of the above technical solution:

[0009] A fixing block is fixedly connected to the top of the motor, and the bottom of the fixing block is fixedly connected to the top of the support plate.

[0010] As a further description of the above technical solution:

[0011] Multiple wheels are fixedly connected to the bottom of the support plate near the middle, and the left and right sides of the wheels are slidably connected to the left and right sides of the square card block.

[0012] As a further description of the above technical solution:

[0013] A support platform is fixedly connected to the top of the support plate, and a connecting column is fixedly connected to the top of the support platform.

[0014] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the motor is first started, which drives the rotating rod to rotate. Then the rotating rod drives the threaded rod to rotate, and the threaded rod will rotate along the threaded hole. Then the threaded sleeve is pushed down, and the threaded sleeve drives the square locking block one to push down. At the same time, the square locking block one drives the fixing plate to push down until the square locking block two and the square locking block one lock the wheel. At this time, the machine cannot move, and the dredging work can be carried out by the digging claw. This achieves the effect of fixing the wheel to make the dredging work more stable.

[0022] 2. In this utility model, when collection is required, the digging claw first scoops up the silt, and then pours it in through the conical funnel. At this time, the silt enters the collection box along the conical funnel. There are four collection boxes around the machine, which facilitates the collection of silt from multiple angles. When the collection box is full, first rotate the threaded cap so that the threaded cap is away from the external thread. At this time, the positioning pin is away from the first circular hole. Then the collection box is removed. Then the collection box drives the positioning pin and the external thread to leave the support plate, thus realizing the function of centralized collection and treatment of silt.

[0039] Working principle: When the machine moves to the position where sludge needs to be removed, the motor 3 is started first. The motor 3 drives the rotating rod 4 to rotate, and then the rotating rod 4 drives the threaded rod 5 to rotate. The threaded rod 5 will rotate along the threaded hole 6, and then the threaded sleeve 7 is pushed down. At this time, the threaded sleeve 7 drives the square locking block 8 to move down, and at the same time, the square locking block 8 drives the fixing plate 9 to move down. At this time, the fixing plate 9 drives the locking post 10 and the square locking block 11 to move down. At the same time, the square locking block 11 will move down along the sliding rod 12 until the square locking block 11 and the square locking block 8 lock the wheel 14. At this time, the machine cannot move, and the sludge removal work can be carried out by the digging claw 20. This achieves the effect of fixing the wheel 14 to make the sludge removal work more stable.

[0040] When collection is required, the sludge is first scooped up by the claw 20 and then poured into the cone-shaped funnel 201. The sludge then flows into the collection box 206 through the cone-shaped funnel 201. There are four collection boxes 206 around the machine, which facilitates the collection of sludge from multiple angles. When the collection box 206 is full, the threaded cap 205 is rotated so that it moves away from the external thread 204. At this time, the positioning pin 203 moves away from the circular hole 202. Then the collection box 206 is removed. The collection box 206 then moves the positioning pin 203 and the external thread 204 away from the support plate 1, thus realizing the function of centralized collection and treatment of sludge.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
