[0021] The river sludge dredging equipment has the following characteristics:

[0022] 1. By setting up a sludge extraction unit consisting of a suction cylinder, a shaking separation component, and a driving flushing mechanism, along with a shaking water discharge mechanism, the suction cylinder extracts and lifts the muddy water near the riverbed and discharges it onto the shaking separation component. The shaking separation component separates the sludge and water. The separated sludge is conveyed to an electric filter belt via a feeding auger, and then transported to the bank. The water falling into the treatment cylinder is extracted by the driving flushing mechanism and sent to a hollow water collection ring at the bottom of the suction cylinder. A flushing head at the bottom of the hollow water collection ring flushes water onto the sludge on the riverbed, turning the sludge into muddy water, which is then extracted and discharged onto the shaking separation component by the suction cylinder. This effectively prevents the spiral conveyor blades inside the suction cylinder from contacting stones in the sludge, effectively protecting the equipment. It can be used in various river channels and has a wide range of applications.

[0023] 2. The sludge and water are separated by a shaking separation component, and the water in the sludge can be reused. Only one dual-axis motor is needed to turn the sludge into muddy water and lift the muddy water at the same time, resulting in low operating costs.

[0024] 3. By setting up a shaking and water-falling mechanism, the protrusions on the shaking plate continuously impact the electric filter belt as the shaking plate moves up and down, allowing the water in the silt on the electric filter belt to slide off quickly, thus removing the water from the silt again. This makes the water removal from the silt transported to the shore more thorough and reduces the difficulty of subsequent silt treatment. Attached Figure Description

[0049] The suction cylinder 81 lifts the muddy water near the river bottom and discharges it onto the shaking separation component 87. The shaking separation component 87 separates the silt and water. The separated silt is transported to the electric filter belt 6 by the feeding auger 7. The shaking water-falling mechanism 9 causes the water in the silt on the electric filter belt 6 to slide off quickly. The water that falls into the treatment cylinder 4 is drawn out by the driving flushing mechanism 88 and sent to the bottom of the suction cylinder 81, and flushes the silt on the river bottom, turning the silt into muddy water. The muddy water is then lifted by the suction cylinder 81 and discharged onto the shaking separation component 87.

[0050] The working process of the river sludge dredging equipment of the present invention is as follows:

[0051] S1. Fix the hull 1 to the river channel. Detect the water depth using the water level sensor 12 at the bottom of the suction cylinder 81. Then, use two hydraulic cylinders 3 to lower the platform 2, bringing the bottom of the suction cylinder 81 closer to the silt at the riverbed. Then, start the dual-shaft motor 83 via the controller 15, which drives the spiral conveying blades 85 inside the suction cylinder 81 to rotate via the rotating shaft 84. A small amount of silt and water is lifted into the suction cylinder 81 and discharged through multiple discharge pipes 86 at the top of the suction cylinder 81 to the inclined filter screen. On 875, the first bevel gear 871 and the second bevel gear 874 in the first transmission mechanism of the shaking separation assembly 87 drive the transmission shaft 873 to rotate, and drive the turntable 877 to rotate, thereby causing the pull rod 878 to move up and down. Driven by the pull rod 878, the inclined filter screen 875 swings up and down rapidly, allowing the sludge to slide down along the inclined filter screen 875 and enter the feeding auger 7 through the feeding hole on the processing cylinder 4. The water in the sludge can pass through the inclined filter screen 875 and be stored in the processing cylinder 4.

[0052] S2. Driven by the first pulley 881 and the second pulley 883 in the second transmission mechanism of the drive flushing mechanism 88, the vertical shaft 882 rotates rapidly, and the horizontal shaft 8810 rotates rapidly under the cooperation of the main bevel gear 8811 and the secondary bevel gear 8812, which in turn drives the drive bar 8815 to rotate rapidly. Through the cooperation of the insert rod 8816 and the reciprocating frame 8814, the slide plate 8813 slides rapidly back and forth, so that the stamping piston 8817 slides rapidly back and forth in the water pressure cylinder 884, which can quickly push out the water in the water pressure cylinder 884 to form a high-pressure water column. The water in the treatment cylinder 4 is then drawn out through the water suction pipe 885 and then transported through the flushing pipe 886 to the hollow water collection ring 8820 at the bottom of the suction cylinder 81. The water is then quickly flushed to the silt at the bottom of the river through the flushing head 8818, turning the silt into muddy water. After being lifted by the suction cylinder 81, the water is discharged onto the inclined filter screen 875 for filtration. The pumping pipe 885 is equipped with a pumping check valve 887, which can only pump water in one direction. The flushing pipe 886 is equipped with a flushing check valve 888, which can also only flush water in one direction.

[0053] S3. The sludge discharged from the treatment cylinder 4 is transported to the electric filter belt 6 by the feeding auger 7, and then transported to the shore by the electric filter belt 6. At this time, the guide rod 91 in the shaking and water-falling mechanism 9 can move up and down with the shaking of the inclined filter screen 875, and then drive the shaking plate 93 to move up and down through the inclined rod 96 and the extension shaft 95. The multiple protrusions 94 on the top surface of the shaking plate 93 can continuously hit the electric filter belt 6, so that the water in the sludge on the electric filter belt 6 can slide down quickly, and the water in the sludge can be removed more thoroughly.

[0054] The above embodiments are for illustrative purposes only and are not intended to limit the invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the invention. Therefore, all equivalent technical solutions should also fall within the scope of the invention and should be defined by the claims.
