The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4As shown, this specific embodiment adopts the following technical scheme: it comprises an engineering dredging vessel 1, a support frame 2 and a conveying pipe 3. The right side of the engineering dredging vessel 1 is provided with a support frame 2, and the conveying pipe 3 is provided on the support frame 2. One end of the conveying pipe 3 is provided with a closed structure, and the other end of the conveying pipe 3 is fixedly provided with a material guide cover 13, which is more conducive to the cleaned sludge entering the conveying pipe 3 through the material guide cover 13;

[0025] It also contains:

[0026] A connecting frame 4, wherein the connecting frame 4 is fixedly arranged at one end of the conveying pipe 3, a motor 5 is fixedly arranged on the connecting frame 4, a spiral auger 6 is screwed in the conveying pipe 3 through a bearing, an output shaft of the motor 5 is connected to the spiral auger 6, and a dredging tool holder 7 is fixedly arranged at the lower end of the spiral auger 6;

[0027] A water filter plate 8 is hingedly arranged on the conveying pipe 3. The water filter plate 8 is an arc-shaped structure with the front and rear sides bent upward, which can effectively prevent the sludge from falling from the front and rear sides of the water filter plate 8. A discharge barrel 9 is fixedly arranged on the conveying pipe 3, and a synchronous driving mechanism 10 connected to the water filter plate 8 is provided on the discharge barrel 9;

[0028] A drainage frame 11, wherein the drainage frame 11 is fixedly arranged on the engineering dredging vessel 1;

[0029] The synchronous drive mechanism 10 comprises:

[0030] A rotating shaft 10-1, wherein the rotating shaft 10-1 is screwed to the discharge barrel 9 through a bearing, the rotating shaft 10-1 is connected to the output shaft of the motor 5 through a pulley and a belt transmission, and a rotating disk 10-2 is fixedly provided on the rotating shaft 10-1;

[0031] A fixed frame 10-3, wherein the fixed frame 10-3 is fixedly arranged on the discharge barrel 9, a slider 10-4 is slidably arranged in a slide groove opened on the fixed frame 10-3, a driving rod 10-5 is rotatably connected to the rotating disk 10-2 through a shaft and a bearing, and one end of the driving rod 10-5 is hinged to the slider 10-4;

[0032] A movable frame 10-6, wherein the movable frame 10-6 is fixedly provided on the slider 10-4, two movable blocks 10-9 are fixedly provided on the movable frame 10-6, a rotating frame 10-7 is screwed on the movable block 10-9, a connecting rod 10-8 is screwed on the rotating frame 10-7, one end of the connecting rod 10-8 is hinged on the water filter plate 8, and track bars 12 are fixedly provided on the front and rear sides of the outer side wall of the discharge barrel 9, and the movable block 10-9 is movably provided on the track bar 12. Through the movement of the movable block 10-9 on the track bar 12, a moving guide can be provided for the movable frame 10-6, thereby improving the stability of the movable frame 10-6.

[0033] When using the utility model, the motor 5 is started, and the motor 5 drives the spiral auger 6 and the dredging tool holder 7 to rotate. The dredging tool holder 7 stirs the silt in the waterway, so that the silt enters the conveying pipe 3, and the silt in the conveying pipe 3 is conveyed to the discharge barrel 9 through the rotating spiral auger 6. At this time, the silt will fall from the discharge barrel 9 to the water filter plate 8. In this process, the rotating shaft 10-1 drives the rotating disk 10-2 to rotate through the transmission of the pulley and the belt. At this time, the driving rod 10-5 can drive the slider 10-4 to reciprocate in the slide groove. The slider 10-4 drives the movable frame 10-6 to move back and forth. The movable frame 10-6 can drive the water filter plate 8 to swing back and forth with its hinge point as the axis through the cooperation of the movable block 10-9, the rotating frame 10-7 and the connecting rod 10-8, which not only improves the water filtering efficiency of the water filter plate 8 for silt, but also prevents silt from sticking to the water filter plate 8. The silt after water filtering will fall onto the engineering dredging ship 1, and the filtered water will drip onto the drainage frame 11. The water can be guided by the drainage frame 11 to drip back onto the waterway.

[0034] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0035] 1. Through the cooperation of the water filter plate 8 and the synchronous drive mechanism 10, the water content in the cleaned sludge can be reduced during the dredging process of the waterway, so that the storage space of the engineering dredging ship 1 can be better utilized and more sludge can be stored;

[0036] 2. Through the cooperation of the track bar 12 and the movable block 10-9, a moving guide can be provided for the movable frame 10-6, thereby improving the stability of the movable frame 10-6.

[0037] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and 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 in the protection scope of the present utility model.
