[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] Please refer to the following Figure 1 and Figure 2 A sludge dredging machine according to an embodiment of the present invention is described.

[0025] like Figure 1 and Figure 2 As shown, the sludge dredging machine according to an embodiment of the present invention includes: a frame 1, a sludge discharge assembly 2, and a dredging assembly 3. The sludge discharge assembly 2 includes a sludge discharge pipe 21, which has a sludge inlet 211 and a sludge outlet 212. The sludge inlet 211 is located at the lower end of the frame 1. The dredging assembly 3 includes a connected driving component 31 and an auger component 32. The driving component 31 is provided on the frame 1. The auger components 32 are at least two groups. The two groups of auger components 32 are provided on both sides of the sludge inlet 211 along a first direction. The auger components 32 extend along a second direction. The first direction, the second direction, and the height direction of the frame 1 are orthogonal to each other. The driving component 31 is used to drive the auger components 32 to rotate so that the sludge dredging machine can move in the roadway. The auger components 32 can drive the sludge to flow into the sludge discharge pipe 21 and be discharged from the sludge outlet 212.

[0026] It can be understood that the first direction is the left and right direction of the sludge dredging machine, the second direction can be the front and back direction of the sludge dredging machine, and the height direction of the frame 1 is the up and down direction of the sludge dredging machine.

[0027] According to the sludge dredging machine of the embodiment of the present invention, when the sludge dredging machine is in operation, the driving component 31 can drive the auger component 32 to rotate. The auger component 32 can spirally convey the sludge to the sludge inlet 211, and then the sludge can be discharged through the sludge outlet 212 of the sludge discharge pipe 21. Moreover, because the auger components 32 are at least two groups, the driving component 31 can drive the auger components 32 to rotate counterclockwise or clockwise, so that the auger components 32 drive the frame 1 forward or backward, thereby facilitating the movement of the sludge dredging machine in the roadway. Therefore, the sludge dredging machine of the embodiment of the present invention can be compact in structure, can move in the roadway, and automatically remove sludge while moving, with high working efficiency.

[0028] In some embodiments, as Figure 1 and Figure 2 As shown, the auger assembly 32 includes an auger shaft 321 and auger blades 322, which are spirally wound around the auger shaft 321. The auger blades 322 are spirally wound around the auger shaft 321. The auger assembly 32 comprises at least two sets of drive components 31, each connected to the auger shafts 321 of the two sets of auger components 32. Specifically, the drive component 31 includes a drive motor 311 and a reducer 312. The drive motor 311 is mounted on the frame 1 and connected to the auger shaft 321 via the reducer 312. When the sludge dredging machine is clearing sludge, the drive motor 311 drives the reducer 312 to rotate, which in turn drives the auger shaft 321 to rotate. The auger blades 322 on the auger shaft 321 can rotate synchronously, allowing the sludge to move to the sludge inlet 211 as the auger blades 322 spirally rotate. The sludge outlet 212 of the sludge discharge pipe 21 can then be connected to a sludge discharge pump, which can drive the sludge at the sludge inlet 211 to be discharged through the sludge discharge pipe 21.

[0029] Optionally, each set of auger components 32 includes a first auger section 323 and a second auger section 324, which are coaxially arranged. The drive component 31 is disposed between the first and second auger sections 323, 324, and is positioned adjacent to the mud inlet 211. The first and second auger sections 323, 324 each consist of an auger shaft 321 and auger blades 322. For example, each set of drive components 31 corresponds to two sets of drive motors 311 and reducers 312. It will be understood that the first auger section 323 is driven by one set of drive motors 311 and reducers 312, while the second auger section 324 is driven by another set of drive motors 311 and reducers 312.

[0030] It is understood that when the sludge dredging machine is dredging sludge, the first auger section 323 and the second auger section 324 can rotate in the counterclockwise and clockwise directions respectively, so that the sludge dredging machine can dredge sludge in both the forward and backward directions at the same time, further improving the efficiency of sludge dredging. When the sludge dredging machine is moving in the roadway, the first auger section 323 and the second auger section 324 can rotate in the same direction, so that the sludge dredging machine can move forward and backward with greater power, thereby improving the stability of the sludge dredging machine.

[0031] In some embodiments, as Figure 2 As shown, the mud discharge assembly 2 also includes at least two first guide plates 22, which are located at the lower end of the frame 1 and arranged between the two groups of auger components 32. The two first guide plates 22 are arranged on both sides of the mud inlet 211 along the second direction, and the first guide plates 22 protrude in the direction toward the mud inlet 211.

[0032] When the sludge dredging machine is working, the auger blade 322 can be driven to rotate by the auger shaft 321, so that the sludge around the auger component 32 is pushed toward the mud inlet 211. Since the first guide plate 22 protrudes in the direction toward the mud inlet 211, it can provide guidance for the movement of the sludge, so that the sludge can enter the mud discharge pipe 21 more smoothly, thereby improving the working efficiency of the sludge dredging machine.

[0033] Alternatively, as Figure 2 As shown, the projection of the first guide plate 22 along the direction perpendicular to the height of the frame 1 is V-shaped, and the tip of the first guide plate 22 is arranged toward the mud inlet 211. It can be understood that the two side plates of the first guide plate 22 can respectively guide the silt around the two groups of auger components 32. Since the tip of the first guide plate 22 is directed toward the mud inlet 211, it can constrain the flow direction of the silt, thereby accelerating the speed at which the silt flows to the mud inlet 211, making the silt dredging machine more efficient.

[0034] Furthermore, if Figure 2 As shown, the mud discharge assembly 2 further includes a second deflector 23, which is located at the lower end of the frame 1 and disposed between the two sets of auger components 32. The two second deflectors 23 are disposed on both sides of the mud inlet 211 along the first direction, and the second deflectors 23 protrude toward the mud inlet 211. It is understandable that the two second deflectors 23 are respectively disposed on the left and right sides of the mud inlet 211.

[0035] When the sludge dredging machine is working, the auger blade 322 can be driven to rotate by the auger shaft 321, so that the sludge around the auger component 32 is pushed toward the mud inlet 211. Since the first guide plate 22 and the second guide plate 23 both protrude in the direction toward the mud inlet 211, they can provide guidance for the movement of the sludge, so that the sludge can enter the mud discharge pipe 21 more smoothly.

[0036] Alternatively, as Figure 2 As shown, the second guide plate 23 has a V-shape when projected along a direction perpendicular to the height of the frame 1. The tip of the second guide plate 23 is arranged toward the mud inlet 211, and the flared end of the second guide plate 23 is arranged toward the reducer 312. By configuring the second guide plate 23 with the above-described structure, the sludge dredging machine according to the embodiment of the present invention can prevent the sludge removed by the auger component 32 from leaking from the gap between the first auger section 323 and the second auger section 324, thereby improving the working efficiency of the sludge dredging machine.

[0037] In some embodiments, as Figure 2 As shown, the mud discharge assembly 2 further includes a diverter plate 24, which is disposed within the mud discharge pipe 21 and adjacent to the mud inlet 211. The diverter plate 24 and the inner wall of the mud discharge pipe 21 define a plurality of mud inlet areas 213. For example, the diverter plate 24 can be generally cross-shaped, thereby dividing the mud discharge pipe 21 into four mud inlet areas 213. By providing the diverter plate 24, the mud dredging machine according to the embodiment of the present invention can divert the mud within the mud discharge pipe 21, thereby reducing the problem of mud discharge pipe 21 blockage and improving the reliability of the mud dredging machine.

[0038] Alternatively, as Figure 1 As shown, the mud discharge assembly 2 further includes a mud guard 25, which is connected to the frame 1 and is located above the auger component 32. It is understood that the mud guard 25 can be an upwardly convex arc-shaped plate, and the mud guard 25 can cover the auger component 32, thereby reducing the problem of mud being flipped out from the upper side of the auger component 32 when the auger component 32 rotates, thereby improving the dredging efficiency of the mud dredging machine.

[0039] In some embodiments, as Figure 1 As shown, the sludge dredging machine further includes a counterweight assembly 4, which includes a counterweight block 42 and a counterweight frame 41. The counterweight frame 41 is provided on the frame 1, and the counterweight block 42 is detachably provided in the counterweight frame 41. It is understood that the sludge dredging machine of the embodiment of the present invention can sink to the bottom of the sludge faster by providing the counterweight block 42, so that the auger blade 322 can dig deeper to facilitate cleaning of the sludge at the bottom.

[0040] Specifically, if Figure 1As shown, the counterweight assembly 4 further includes a counterweight plate 43, which is mounted on the frame 1. The counterweight block 42 is detachably mounted on the counterweight plate 43. The counterweight frame 41 is arranged around the counterweight block 42 to prevent the counterweight block 42 from falling. For example, there may be multiple counterweight blocks 42, which can be assembled according to actual needs, thereby increasing the flexibility of the sludge dredging machine during use.

[0041] In summary, the working principle of the sludge dredging machine of the present invention is as follows.

[0042] like Figure 1 and Figure 2 As shown, when the sludge dredging machine is working, the drive motor 311 is controlled to rotate, and the drive motor 311 drives the auger shaft 321 to rotate through the reducer, and the spiral auger blades 322 arranged on the periphery of the auger shaft 321 rotate synchronously. The rotation of the auger blades 322 causes the sludge around the sludge dredging machine to be pushed toward the mud inlet 211.

[0043] The first guide plate 22 guides the silt to the mud inlet 211 of the mud discharge pipe 21, where it can be pushed out from the upper end of the mud discharge pipe 21 or connected to a suction pump to extract the silt. A diverter plate 24 is provided at the lower end of the mud discharge pipe 21 to divert the silt output from the multiple diverter plates 24, preventing blockage of the mud discharge pipe 21. The second guide plate 23 is provided to divert the silt and prevent it from leaking out of the reducer. The mud guard 25 reduces the outward movement of the silt, improving the efficiency of silt removal. The counterweight 42 enables the silt excavator to dig deeper, facilitating the removal of silt from the bottom.

[0044] In addition, the driving component 31 can control the different rotation directions of the multiple auger shafts 321, so that the sludge excavator can automatically move in different directions, thereby facilitating the cleaning of sludge in the tunnel.
