Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a dredging device for water conservancy projects includes a trolley 101, which is connected to a lifting plate 104 via a lifting structure. A sludge pump 106 is connected through the lifting plate 104. The sludge pump 106 is provided with a sludge inlet 108 for sucking in sludge. The output end of the sludge pump 106 is connected to a sludge discharge pipe 107. A sludge baffle 105 is connected to the lifting plate 104. Two ditch width adaptation structures are symmetrically provided on the sludge baffle 105. A weed chopping structure is provided on the lifting plate 104.

[0026] In this embodiment, the lifting structure drives the lifting plate 104 to rise and fall to adapt to the depth of the irrigation ditch. The silt baffle 105 plays a role in concentrating the silt in the irrigation ditch and reducing silt residue. The ditch width adaptation structure adjusts the effective range of the silt baffle 105. The weed chopping mechanism chops up weeds and other impurities in the silt, making it easier for the sludge pump 106 to extract the silt blocked by the silt baffle 105. The silt extracted by the sludge pump 106 is discharged from the irrigation ditch through the sludge discharge pipe 107.

[0027] In one embodiment, such as Figure 1As shown, the lifting structure includes two guide columns 103 connected to the lifting plate 104. The guide columns 103 are slidably connected to the trolley 101. A first telescopic rod 102 is connected to the trolley 101. The output end of the first telescopic rod 102 is connected to the lifting plate 104. The guide columns 103 guide the lifting plate 104. The extension and shortening of the first telescopic rod 102 correspond to the lifting plate 104 rising and falling, respectively.

[0028] In one embodiment, such as Figure 3 and Figure 5 As shown, the ditch width adaptation structure includes a chute 202 set on the silt baffle 105, a guide strip 203 slidably disposed in the chute 202, the guide strip 203 being connected to the extension plate 201, the extension plate 201 being in slidable contact with the silt baffle 105, and an extension drive assembly on the lifting plate 104 for moving the extension plate 201. The extension drive assembly includes a through groove 206 opened on the lifting plate 104, the through groove 206 matching the chute 202, a connecting block 204 connected to the guide strip 203, and a second telescopic rod 205 connected to the lifting plate 104. The output end of the second telescopic rod 205 is connected to the connecting block 204. The extension of the second telescopic rod 205 drives the connecting block 204 to move, the connecting block 204 drives the guide strip 203 to slide in the chute 202, and the guide strip 203 drives the extension plate 201 to move along the silt baffle 105, extending the silt baffle 105 to adapt to the width of the irrigation ditch and improve dredging efficiency.

[0029] In one embodiment, such as Figures 1-2As shown, the weed chopping structure includes a first fixed sleeve 301 and a second fixed sleeve 302 that are connected through the lifting plate 104. The lower ends of both the first fixed sleeve 301 and the second fixed sleeve 302 are provided with a circumferential array of fixed blades 303. A first rotating shaft 304 is rotatably mounted inside the first fixed sleeve 301, and a second rotating shaft 305 is rotatably mounted inside the second fixed sleeve 302. The lower ends of both the first rotating shaft 304 and the second rotating shaft 305 are provided with a circumferential array of rotating blades 306. The lifting plate 104 is equipped with a mechanism to drive the first rotating shaft 306. 4. A chopping drive structure for rotating the second shaft 305, comprising a first synchronous pulley 401 coaxially connected to the first shaft 304, a fixed column 402 connected to the lifting plate 104, the fixed column 402 being parallel to the first synchronous pulley 401, a second synchronous pulley 403 rotatably mounted on the fixed column 402, a matching synchronous belt 409 between the first synchronous pulley 401 and the second synchronous pulley 403, a first gear 404 coaxially connected to the second synchronous pulley 403, and the second shaft 304... A second gear 405 is coaxially connected to the first gear 404, which meshes with the second gear 405. A first bevel gear 406 is coaxially connected to the second rotating shaft 305. A drive motor 408 is connected to the lifting plate 104. The power output shaft of the drive motor 408 is connected to the second bevel gear 407. The first bevel gear 406 and the second bevel gear 407 mesh. The drive motor 408 drives the first bevel gear 406 to rotate through the second bevel gear 407. The first bevel gear 406 drives the second rotating shaft 305 to rotate. The second gear 405 connected to the rotating shaft 305 drives the first gear 404 to rotate, the first gear 404 drives the second synchronous pulley 403 to rotate, the second synchronous pulley 403 drives the first synchronous pulley 401 to rotate through the synchronous belt 409, and the first synchronous pulley 401 drives the first rotating shaft 304 to rotate. The rotating blades 306 on the first rotating shaft 304 and the second rotating shaft 305 cooperate with the fixed blades 303 to chop up the weeds in the sludge. The chopping effect is good and effectively reduces the risk of clogging of the sludge pump 106.

[0030] In one embodiment, such as Figure 4 As shown, the sludge baffle 105 is a steel plate bent into a V shape. The bent part of the sludge baffle 105 is a cylindrical surface, which makes the sludge move closer to the sludge inlet 108, so that the sludge pump 106 can easily pump out the sludge. The cylindrical surface has no dead corners, making it easy to clean.

[0031] In one embodiment, such as Figure 3 As shown, the gap between the fixed blade 303 and the rotating blade 306 is 1 to 5 mm to avoid wear caused by direct contact and friction between the rotating blade 306 and the fixed blade 303.

[0032] The above embodiment discloses a dredging device for water conservancy projects. The guide column 103 guides the lifting plate 104. The extension and retraction of the first telescopic rod 102 correspond to the rising and falling of the lifting plate 104, respectively, to adapt to the depth of the water conservancy ditch. The silt baffle 105 contacts the bottom of the water conservancy ditch, concentrating the silt within it. The sludge pump 106 extracts the silt concentrated by the silt baffle 105 through the sludge inlet 108. The extension of the second telescopic rod 205 moves the connecting block 204, which in turn moves the guide strip 203 within the chute 202. The guide strip 203 causes the extension plate 201 to move along the silt baffle 105, extending the silt baffle 105 to adapt to the depth of the water conservancy ditch. To improve dredging efficiency by adjusting the width of the irrigation ditch, the drive motor 408 drives the first bevel gear 406 to rotate via the second bevel gear 407. The first bevel gear 406 drives the second rotating shaft 305 to rotate. The second gear 405 connected to the second rotating shaft 305 drives the first gear 404 to rotate. The first gear 404 drives the second synchronous pulley 403 to rotate. The second synchronous pulley 403 drives the first synchronous pulley 401 to rotate via the synchronous belt 409. The first synchronous pulley 401 drives the first rotating shaft 304 to rotate. The rotating blades 306 on the first rotating shaft 304 and the second rotating shaft 305, together with the fixed blades 303, chop up the weeds in the silt. The chopping effect is good, effectively reducing the risk of clogging of the sludge pump 106.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
