[0043] Hereinafter, a river channel environmental protection dredging device based on a water conservancy project will be referred to as a dredging device.

[0044] When the present invention is in use, the river channel is divided into several sections, the river channel is blocked in sections, the water in the river channel to be dredged is pumped out, the motor drives the electric wheel to rotate, and further drives the dredging device to move. At the same time, the worker holds the handle of the dredging device and pushes the rear side of the dredging device upward. At this time, the bucket 2 on the front side of the dredging device is inserted downward into the silt. Since the separation plate 7 is composed of several intercepting bars and there are several gaps, when the separation plate 7 separates the sludge, the silt scooped up by the bucket 2 moves upward along the inclined moving plate 71. At this time, the smaller silt blocks pass through the gaps on the separation plate 7 and fall into the inner cylinder 3 and pass through the guide plate 1. 05 guide continues to move backward, the large pieces of silt staying on the separation plate 7 are moved along the inclined moving plate 71 to the horizontal separation frame 72, the water inlet pipe 101 is connected to the external water pump through the hose, and water is pumped into the high-pressure nozzle 8, and the water is sprayed out after being pressurized by the high-pressure nozzle 8, and the large pieces of sludge are dispersed by the water flow. It should be noted that the high-pressure nozzle 8 is inclined from the inner tube 1 3 to the inner tube 2 4, and the flushing water flow drives the dispersed silt to move to the inner tube 2 4, preventing the dispersed sludge from flowing out of the inner tube 1 3. During the movement of the silt cleaning device, the bucket 2 shovels up the silt and screens the silt through the separation plate 7. Small pieces of silt directly pass through the separation plate The sludge and water are separated from the plate 7 and enter the inner cylinder 2 4. The slider connected to the annular slide rail 103 drives the inner cylinder 2 4 and the guide plate 105 to rotate, guiding the small pieces of sludge and water to continue to move backward through the filter screen 201, and the impurities are filtered through the filter screen 201. At this time, the sludge and water pass through the filter screen 201 and enter the inner cylinder 4 6. Then, the sludge and water are pumped away by the sludge pump connected to the inner cylinder 4 6. The impurities intercepted by the filter screen 201 remain in the inner cylinder 3 5. It should be noted that after the sludge is separated and broken up by the separation plate 7, the garbage in the sludge remains on the horizontal separation frame 72. At this time, the electric separator 72 connected to the horizontal separation frame 72 is used to separate the sludge. The machine drives the horizontal separation frame 72 to rotate clockwise when viewed from the front to tilt the horizontal separation frame 72. The high-pressure nozzle 8 sprays water to flush the garbage remaining on the horizontal separation frame 72 so that it slides into the inner tube 2 4 and is driven to move into the inner tube 3 5 by the guide plate 105. During this process, the guide plate 105 stirs the garbage and water, and the water flow further flushes the silt remaining on the garbage. When the garbage and water flow enter the inner tube 3 5, the filter screen 201 intercepts the garbage and collects the garbage in the inner tube 2 4 and the inner tube 3 5, thereby preventing the garbage wrapped in the silt from flowing away during the silt cleaning process and polluting the downstream river.

[0045] It should be noted that, in the present invention, when the motor connected to the horizontal separation frame 72 drives the horizontal separation frame 72 to rotate clockwise from the front to rear perspective so that the horizontal separation frame 72 is tilted, the present invention stops moving at this time.

[0046] Furthermore, the garbage staying in the inner cylinder 2 4 and the inner cylinder 3 5 has the problem of clogging the filter 201. Therefore, when the present invention is working, the slider connected to the annular slide rail 2 104 drives the inner cylinder 4 6 and the connecting frame 202 to rotate, and further drives the first scraper 203 to rotate and scrape the garbage accumulated on the front side of the filter 201 to prevent the filter 201 from being blocked by the garbage. At the same time, the first scraper 203 rotates to squeeze the garbage into the discharge port 30101 through the discharge port 1 5001 and the through groove 1001, and the slider connected to the electric slide rail 302 drives the second scraper 303 to rotate at the discharge port. The first scraper 203 moves left and right in 30101, and the garbage in the discharge port 30101 is scraped into the collecting net 305 for collection. The method of the first scraper 203 squeezing the garbage into the discharge port 30101 is as follows: the first scraper 203 guides the garbage to move along the first scraper 203 when rotating. When the first scraper 203 rotates to the discharge port 5001, the garbage guided by the first scraper 203 will enter the discharge port 5001. At this time, the garbage located in the discharge port 5001 squeezes the plug set on the through slot 1001, so that the through slot 1001 opens, allowing the garbage to enter the discharge port 30101.

[0047] Furthermore, if there are strips of garbage or shorter branches among the garbage wrapped in the sludge, they will be inserted into the mesh of the filter 201. At this time, the cutter 205 in contact with the front side of the filter 201 is driven by the rotation of the connecting frame 202 to rotate and cut off the branches and linear garbage inserted in the mesh of the guide plate 105. After cutting, the garbage located in the front side of the filter 201 is guided by the first scraper 203 to pass through the discharge port 5001 and the through groove 1001 into the discharge port 30101. Since the through groove 1001 and the discharge port 30101 are both arranged on the lower side of the dredging device, there is a problem of sludge water being discharged through the through groove 1001. Therefore, a connecting port is provided on the second collecting bin 301. 30103, directly connect the sludge pump here to pump out the sludge water entering the discharge port 30101. The garbage entering the discharge port 30101 is driven by the slider connected to the electric slide rail 302 to move the second scraper 303 left and right, and the garbage in the discharge port 30101 is scraped into the collection net 305 for collection. It should be noted that a drain port 30301 is provided on the second scraper 303, and gauze is provided on the drain port 30301. When the second scraper 303 scrapes the garbage, the moving garbage is squeezed with the garbage in the collection net 305, so that the sewage in the collection net 305 passes through the drain port 30301 on the second scraper 303 and enters the discharge port 30101 to be pumped out.

[0048] Furthermore, the garbage that passes through the mesh of the filter 201 will directly enter the inner cylinder 24 6, so a first collecting bin 204 is provided. When the cutter 205 cuts off the garbage inserted in the mesh of the filter 201, the garbage that passes through the mesh of the guide plate 105 falls downward and is collected by the first collecting bin 204. It should be noted that when the first collecting bin 204 is collecting garbage, the state of the linear drive member 206 and the extrusion plate 207 is as follows: when looking from left to right, the linear drive member 206 is driven by the driver 208 to rotate clockwise, so that the linear drive member 206 is abutted against the upper side of the inner cylinder 3 5, so as to prevent the extrusion plate 207 from affecting the first collecting bin 204 from collecting the garbage that passes through the filter 201. When the dredging device processes the garbage accumulated on the separation plate 7, the linear drive member 206 is driven by the driver 208 to rotate as shown in the figure. Figure 10 In the state shown, the linear drive member 206 drives the extrusion plate 207 to move downward, squeezing the garbage inside the first collecting bin 204 so that the garbage inside the first collecting bin 204 passes through the discharge port of the first collecting bin 204, and then passes through the second discharge port 5002 and the second through slot 1002 into the discharge port 30101, and then the second scraper 303 scrapes the garbage into the collection net 305.

[0049] It should be noted that when the collection net 305 is full of garbage, the worker holds the fixed frame 304 and pulls the fixed frame 304 away from the dredging equipment to disengage the fixed frame 304 from the placement slot 30102. Then the worker removes the mesh port of the collection net 305 from the fixed frame 304 and replaces it with a new collection net 305. The method for disengaging the fixed frame 304 from the placement slot 30102 is that the worker pulls the fixed frame 304 hard so that the spring ball on the fixed frame 304 is squeezed out of the slot in the placement slot 30102 and the fixed frame 304 can be taken out. The method for replacing the new collection net 305 is that the worker puts the mesh port of the collection net 305 on the fixed frame 304, and then pushes the fixed frame 304 into the placement slot 30102 so that the ball on the fixed frame 304 is stuck in the corresponding slot to complete the replacement.

[0050] When the broken up sludge and water flow into the inner tube four 6, they are pumped away by the sludge pump connected to the inner tube four 6. During this process, the inner tube four 6 rotates, driving the broken up sludge and water inside to rotate, so that the sludge and water are fully mixed, and the sludge inside the inner tube four 6 is prevented from settling.

[0051] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
