The silt will affect the smooth flow of water and increase the risk of flooding. Therefore, regular dredging can restore and maintain the designed flood discharge capacity. Currently, dredging mainly uses mechanical equipment such as suction dredgers to directly remove the silt at the bottom of the riverbed or reservoir; When the existing water conservancy project dredger is cleaning, it stirs the silt at the bottom of the river channel through the dredger, making the silt stirred into mud, and then pumps the mud into the mud tank through a dredging pump, resulting in inconvenient overall operation, low dredging efficiency, and the existing dredger is prone to pipeline blockage during use, thereby reducing the treatment effect of the silt.

A moving plate is fixedly installed on the top plate. Two guide rods are slidably connected inside the moving plate.

[0006] Preferably, the device further includes two connecting frames. The top of the connecting frame close to the material guiding frame is fixedly connected to the moving plate.

[0010] Preferably, the upper surface of the top plate is fixedly connected to the back of the moving plate. The bottoms of the two guide rods are fixedly connected to the two stabilizing plates.

[0011] On the other hand, the present invention also provides a method for dredging a water conservancy project, which is realized by using the dredging device. The dredging method includes: During use, first control the operation of the first hydraulic cylinder. The first hydraulic cylinder drives the stabilizing plate to move downward, drives the material guiding frame to move downward, so that the silt cylinder outside the material guiding frame extends to the bottom of the river channel, and the arc plate fits on the bottom of the river channel. Turn on Motor 1. Motor 1 drives the drive shaft to rotate. The drive shaft drives the auger body to rotate at high speed, sucking the silt inside the arc plate and at the bottom of the river channel, transferring the silt into the inside of the connecting pipe. The scraping plate at the front end of the drive shaft squeezes and crushes the harder silt or earth and stone to prevent the silt cylinder from being blocked. The sucked silt enters the inside of the material guiding frame through the connecting pipe. Motor 2 operates. Motor 2 drives the rotating plate to rotate, drives the swing rod to move, drives the cross plate and the linkage rod to move, so that the U-shaped frame reciprocates inside the material guiding frame. At this time, the scraping plate inside the U-shaped frame scrapes the silt, and drives the silt to the shore under the condition of cycling this operation step, and cooperates with the transfer vehicle to transfer the silt.

[0012] Preferably, when the U-shaped frame drives the scraping plate to move to the right, the scraping plate contacts the silt to form a resistance, so that the scraping plate fits on the limiting plate, restricting the scraping plate from continuing to rotate along the rotating shaft; when the U-shaped frame drives the scraping plate to move to the left, blocked by the silt, the scraping plate rotates counterclockwise along the rotating shaft, causing the scraping plate to lift up and not push the silt to move to the left. During the reciprocating movement of the scraping plate, the silt is driven to move to the right and gradually moves to the right end of the material guiding frame for transfer.

[0013] Preferably, when it is necessary to adjust the position of the silt cylinder in the river channel, control the second hydraulic rod to adjust the distance between the two connecting frames. When the distance between the two connecting frames becomes smaller, the silt cylinder moves towards the position where the river channel is located. At this time, control the third hydraulic rod to operate. The third hydraulic rod drives the counterweight to move, so that the center of gravity of the whole device is between the two connecting frames. When the distance between the two connecting frames becomes larger, the silt cylinder will be closer to the edge of the river channel.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. For this dredging device for water conservancy projects, during use, first control the first hydraulic rod to operate to drive the stabilizing plate to move downwards, drive the material guiding frame to move downwards, so that the silt cylinder outside the material guiding frame can extend to the bottom of the river channel, make the arc plate fit on the bottom of the river channel, turn on Motor 1 to drive the drive shaft to rotate, drive the auger body to rotate at high speed, and can suck the silt inside the arc plate and at the bottom of the river channel. The scraping plate at the front end of the drive shaft can squeeze and crush the harder silt or earth and stone, which can prevent the silt cylinder from being blocked. Motor 2 drives the rotating plate to rotate, so that the U-shaped frame can reciprocate inside the material guiding frame. At this time, the scraping plate inside the U-shaped frame can scrape the silt to achieve the effect of scraping silt. Under the condition of cycling this operation step, the silt can be driven onto the shore and cooperate with the transfer vehicle to transfer the silt, solving the problem that the existing device stirs the silt at the bottom of the river channel, making the silt stirred into mud, and then pumping the mud into the mud tank through a dredging pump, resulting in inconvenient overall operation and low dredging efficiency.

[0015] 2. For this dredging device for water conservancy projects, when the U-shaped frame drives the scraper to move to the right, the scraper will contact the silt to form resistance, causing the scraper to fit on the limiting plate, which can restrict the scraper from continuing to rotate along the rotating shaft. When the U-shaped frame drives the scraper to move to the left, blocked by the silt, the scraper will rotate counterclockwise along the rotating shaft, enabling the scraper to be lifted up and not pushing the silt to move to the left. During the reciprocating movement of the scraper, the silt will be driven to move to the right and gradually move to the right end of the material guiding frame for transfer, achieving the effect of unidirectional scraping of silt.

[0016] 3. For this dredging device for water conservancy projects, when it is necessary to adjust the position of the silt cylinder in the river channel, control the second hydraulic rod so that the distance between the two connecting frames can be adjusted. When the distance between the two connecting frames becomes smaller, the silt cylinder can move towards the position where the river channel is located. At this time, to ensure the balance between the two connecting frames, it is necessary to control the third hydraulic rod to operate and drive the counterweight to move, so that the center is between the two connecting frames. When the distance between the two connecting frames becomes larger, the silt cylinder will be closer to the edge of the river channel, achieving the effect of adjusting the position where the silt cylinder extends into the river channel and enabling dredging at different positions.

The drive shaft 5 and the auger main body 7 are arranged inside the sludge cylinder 1. An auger main body is fixedly sleeved on the outer wall of the drive shaft 5, and a scraping plate 8 is fixedly installed at the bottom end of the drive shaft 5; The device further includes: a material guiding frame 10 for guiding materials, a fixing plate 9 for fixing, and a scraping blade 15 for scraping mud. A fixing plate 9 is fixedly sleeved on the outer wall of the middle and upper part of the sludge cylinder 1. One end of the fixing plate 9 is fixedly welded with a material guiding frame 10. Slide bars 11 are fixedly installed on both sides of the material guiding frame 10. One end of the two slide bars 11 is slidably connected with a slide plate 12. A U-shaped frame 13 is fixedly installed between the two slide plates 12. A rotating shaft 14 is rotatably connected inside the U-shaped frame 13, and a scraping blade 15 is fixedly sleeved on the rotating shaft 14; On the inner sides of both ends of the U-shaped frame 13, two limiting plates 16 are fixedly installed. On the outer wall of the U-shaped frame 13, a linkage rod 17 is fixedly installed. At the other ends of the two linkage rods 17, a cross plate 18 is fixedly installed.

On the outer wall of the material guiding frame 10, a support plate 22 is fixedly installed. On the outer wall of the support plate 22, a second motor 21 is fixedly installed. At the bottom of the material guiding frame 10, a partition plate 36 is fixedly installed. Specifically, when the device is in use, first control the operation of the first hydraulic rod 24. The first hydraulic rod 24 will drive the stabilizing plate 23 to move downward, driving the material guiding frame 10 to move downward, so that the sludge cylinder 1 outside the material guiding frame 10 can extend to the bottom of the river channel, and the arc-shaped plate 2 is attached to the bottom of the river channel. At this time, turn on the first motor 4. The first motor 4 will drive the drive shaft 5 to rotate. The drive shaft 5 will drive the auger main body 7 to rotate at a high speed, and can suck the sludge inside the arc-shaped plate 2 and at the bottom of the river channel, and can transfer the sludge into the inside of the connecting pipe 6. The scraping plate 8 at the front end of the drive shaft 5 can squeeze and crush harder sludge or soil and stone, which can avoid the blockage of the sludge cylinder 1, and solves the problem that the existing dredger is prone to cause pipeline blockage during use, thereby reducing the sludge treatment effect.

When the U-shaped frame 13 drives the scraping plate 15 to move to the left, blocked by the sludge, the scraping plate 15 will rotate counterclockwise along the rotating shaft 14, so that the scraping plate 15 can be lifted up and will not push the sludge to move to the left. During the reciprocating movement of the scraping plate 15, the sludge will be driven to move to the right and gradually move to the right end of the material guiding frame 10 for transfer.
