[0002] my country has numerous rivers and lakes. Siltation causes riverbeds to rise, affecting flood control and threatening people's lives and property. Dredging is an essential step in water conservancy construction to solve the problem of river siltation. Usually, dredging machinery is used to remove the silt deposited on the riverbed through pipes and pumps, thereby clearing the blockage.

[0003] In an existing dredging device for water conservancy construction, a filter screen is used to filter the water in the silt, and then the filter screen is scraped to scrape the silt into the collection box. However, during subsequent silt introduction, the silt in the collection box will return to the dredging device, resulting in low dredging efficiency. Therefore, an improved dredging device for water conservancy construction is needed to solve the above problems. Utility Model Content

[0024] Example 1:

[0025] Please see Figure 1-3 This utility model provides a technical solution: a dredging device for water conservancy construction, including a dredging box 1, a mud inlet pipe 4 fixedly installed on the left side of the dredging box 1, a collection hopper 5 fixedly installed at the bottom of the dredging box 1, a drawer 6 provided inside the collection hopper 5, a filter screen 7 fixedly installed inside the dredging box 1, a dredging mechanism 2 provided inside the dredging box 1, and a water removal mechanism 3 provided at the bottom of the dredging mechanism 2.

[0026] The dredging mechanism 2 includes a cleaning component 21 and a sliding component 22, with the sliding component 22 disposed outside the cleaning component 21.

[0027] Furthermore, the cleaning component 21 includes a motor 211, which is fixedly installed on the top of the sludge removal box 1. A reciprocating lead screw 212 is fixedly installed at the output end of the motor 211. A gear 213 is fixedly installed on the outside of the reciprocating lead screw 212. A cleaning brush 214 is rotatably installed inside the sludge removal box 1. A gear 215 is fixedly installed on the outside of the cleaning brush 214. A sliding block 216 is provided on the outside of the reciprocating lead screw 212. A scraping ring 217 is provided on the front of the sliding block 216. An installation box 218 is fixedly installed inside the sludge removal box 1. A scraper 219 is fixedly installed on the back of the sliding block 216 to prevent sludge from affecting the operation of the reciprocating lead screw 212 and to ensure the stable sliding of the sliding block 216. The scraping ring 217 moves outside the cleaning brush 214 to scrape off the sludge on the surface of the cleaning brush 214, ensuring that no hard sludge adheres to the surface of the cleaning brush 214.

[0028] Furthermore, the sliding block 216 is slidably installed inside the mounting box 218, the scraping ring 217 is set outside the cleaning brush 214, the gear 1 213 meshes with the gear 215, and the scraper 219 fits against the filter screen 7 to prevent the filter holes on the filter screen 7 from becoming clogged.

[0029] Furthermore, the sliding assembly 22 includes a connecting rod 221, which is rotatably mounted on the left side of the scraper 219. A sliding frame 222 is rotatably mounted on the end of the connecting rod 221 away from the scraper 219. A slide rail 223 is fixedly mounted on the inner side of the bottom of the sludge collection box 1. A spring 224 is fixedly mounted inside the sludge collection box 1. A sliding plate 225 is fixedly mounted on the end of the spring 224 away from the sludge collection box 1. A baffle 226 is fixedly mounted on the top of the sliding plate 225. A push plate 227 is fixedly mounted on the bottom of the sliding plate 225, ensuring that the sludge inside the collection hopper 5 does not return to the sludge collection box 1, thereby increasing the efficiency of sludge removal.

[0030] Furthermore, the sliding frame 222 is slidably installed outside the slide rail 223. The sludge removal box 1 and the baffle 226 are provided with a sliding groove at the corresponding positions. The sliding plate 225 and the baffle 226 are slidably installed inside the sliding groove. The sludge removal box 1 and the scraper 219 are provided with a mud dropping trough at the corresponding positions. The collection hopper 5 is set at the bottom of the mud dropping trough. The push plate 227 is set inside the collection hopper 5. The sliding plate 225 opens and closes as the scraper 219 rises and falls, thus blocking the mud dropping trough.

[0031] Example 2:

[0032] Please see Figure 4Furthermore, in conjunction with Embodiment 1, it is further found that the water removal mechanism 3 includes a heating box 31, which is fixedly installed on the outside of the collection hopper 5. A friction disc 32 is fixedly installed inside the heating box 31. A gear 33 is fixedly installed at the bottom of the cleaning brush 214. A gear 4 34 is rotatably installed inside the heating box 31. A friction block 35 is fixedly installed at the bottom of the gear 4 34. A fan 36 is fixedly installed on the front of the heating box 31, so that the drawer 6 can store more sludge and there is no need to clean the sludge multiple times.

[0033] Furthermore, gear 33 meshes with gear 4 34, friction block 35 fits against friction disc 32, and ventilation holes are provided at the corresponding positions of heating box 31 and collection hopper 5. Hot air is blown into the collection hopper 5 by fan 36 to further treat the moisture on the surface of the silt.

[0034] In actual operation, when this device is used, the sludge enters the sludge cleaning box 1 through the sludge inlet pipe 4. The filter screen 7 filters the water in the sludge. The motor 211 is started, and the output end of the motor 211 drives the reciprocating screw 212 to rotate. The rotation of the reciprocating screw 212 causes the scraper 219 to move back and forth, thereby scraping the sludge on the surface of the filter screen 7. When the reciprocating screw 212 rotates, it drives the gear 215 to rotate through the gear 1 213, thereby causing the cleaning brush 214 to rotate and clean the sludge adhering to the surface of the reciprocating screw 212. The scraping ring 217 moves outside the cleaning brush 214 to scrape off the sludge on the surface of the cleaning brush 214. As the scraper 219 moves downward, it drives the connecting rod 221 to move. The movement of the connecting rod 221 causes the sliding frame 2 to move. 22 slides outside the slide rail 223. When the sliding bracket 222 moves to the position of the baffle 226, it pushes the baffle 226, causing the sliding plate 225 to move to the left, thus exposing the mud trough. The scraper 219 pushes the sludge into the collection hopper 5. When the scraper 219 moves upward, the spring 224 loses its limit and rebounds. The pusher 227 pushes the sludge inside the collection hopper 5 into the drawer 6. While the cleaning brush 214 rotates, it drives the gear 33 to rotate. The rotation of the gear 33 drives the gear 4 to rotate, thus causing the friction block 35 to rub against the friction plate 32 and generate heat. The fan 36 blows the hot air into the collection hopper 5 to further treat the moisture on the surface of the sludge, so that the drawer 6 can store more sludge and does not need to clean the sludge multiple times.
