DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] See attached Figure 1-3 As shown, a sludge dredging device in this embodiment includes a frame 1, a left driving mechanism 5, a right driving mechanism 12, a main motor 2, a sleeve 13, a rotating shaft 16, a spiral blade 17, a gathering mechanism 4 and a conveying pipe 3, wherein the left driving mechanism 5 and the right driving mechanism 12 are symmetrically arranged on both sides of the frame 1; the main motor 2 and the sleeve 13 are fixedly connected in the middle of the frame 1, and a central groove 14 and a conveying groove 15 are arranged at the central axis of the sleeve 13, and the central groove 14 and the conveying groove 15 are coaxially connected, and the diameter of the central groove 14 is smaller than the diameter of the conveying groove 15; The rotating shaft 16 extending from the motor 2 passes through the central groove 14 and the conveying groove 15 and extends downward to connect to the gathering mechanism 4; the spiral blade 17 is arranged in the conveying groove 15 and is coaxially connected to the rotating shaft 16; the conveying pipe 3 is connected to the middle part of the sleeve 13 and is connected to the top of the conveying groove 15; the gathering mechanism 4 includes a mounting frame 41 and a plurality of arc-shaped plow blades 44, the mounting frame 41 is fixedly connected to the lower end of the rotating shaft 16, and the plane area formed by the rotation of the mounting frame 41 is larger than the area of ​​the sleeve 13; the plurality of arc-shaped plow blades 44 are fixedly connected to the lower surface of the mounting frame 41 in a circular array.

[0019] The main motor 2 is started, and the mounting frame 41 is driven to rotate through the rotating shaft 16. The rotating arc-shaped plowshares 44 scrape, turn up, and loosen the sludge. Under the action of the arc-shaped plowshares 44, the sludge gathers toward the rotation center and is directly below the rotating shaft 16 and the sleeve 13. Under the action of the sleeve 13 and the spiral blades 17, the sludge is lifted and output from the conveying pipe 3. The rotating mounting frame 41 and the arc-shaped plowshares 44 expand the area for grabbing sludge, grab sludge in a larger range, reduce the frequency of moving the sludge dredging device, and improve work efficiency.

[0020] In order to make the mounting frame 41 rotate smoothly, the utility model is further configured as follows: the mounting frame 41 is in a circular plane shape.

[0021] In order to filter large-sized agglomerated sludge, the utility model is further configured as follows: the mounting frame 41 includes a plurality of concentrically arranged annular rings 42 and a plurality of spokes 43; the spokes 43 extend radially from the center of the annular ring 42; and the spokes 43 are welded to the intersection of the annular ring 42. By adjusting the spacing between adjacent annular rings 42, the radius difference between adjacent annular rings 42 is smaller than the diameter of the agglomerated sludge, and the large-sized agglomerated sludge cannot pass through the mounting frame 41, and only the fine sludge can pass through the mounting frame 41 and be captured by the spiral blades 17 and transported to the transport pipe 3.

[0022] In order to prevent sludge from clogging between the central groove 14 and the rotating shaft 16, the utility model is further configured as follows: a sealing mechanism 18 is provided between the lower end of the central groove 14 and the rotating shaft 16. Under the action of the spiral blade 17, the sludge cannot pass through the sealing mechanism 18 and can only move along the conveying groove 15 and the conveying pipe 3.

[0023] In order to facilitate the movement of the sludge dredging device to other locations for cleaning operations, the utility model is further configured as follows: the left driving mechanism 5 includes a driving motor 11, a reducer 6, a wheel axle 7 and a track wheel 8, the driving motor 11 and the reducer 6 are fixedly connected to the frame 1, the driving motor 11 drives the reducer 6 to operate, the output end of the reducer 6 is connected to the wheel axle 7, and the wheel axle 7 is fixedly connected to the center of the track wheel 8; the right driving mechanism 12 has the same structure as the left driving mechanism 5. Start the driving motor 11, and the driving motor 11 drives the track wheel 8 to rotate through the reducer 6 and the wheel axle 7. When the left driving mechanism 5 and the right driving mechanism 12 are running at the same time, the sludge dredging device moves forward. When the left driving mechanism 5 stops and the right driving mechanism 12 is running, the sludge dredging device turns left. When the left driving mechanism 5 is running and the right driving mechanism 12 is stopped, the sludge dredging device turns right.

[0024] In order to prevent the left driving mechanism 5 and the right driving mechanism 12 from sinking into the mud, causing the mud dredging device to be submerged in the mud and unable to move. The utility model is further configured as follows: the lower surface of the frame 1 is connected to a bracket 9, and the bracket 9 is connected to an airbag 10. By inflating the airbag 10, the airbag 10 swells, increasing the overall buoyancy of the mud dredging device, and the airbag 10 can float with the mud. Prevent the left driving mechanism 5 and the right driving mechanism 12 from sinking into the mud and being submerged in the mud. After the spiral blade 17 transports the mud, deflate the airbag 10. At this time, the left driving mechanism 5 and the right driving mechanism 12 can be operated.

[0025] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
