[0051] The implementation principle of the sludge dewatering machine is as follows: when the sludge needs to be dewatered, the sludge is added to the feeding hopper 11, the sludge enters the conveying pipe 2 close to the feeding hopper 11, and the driving assembly 8 is started to drive the conveying auger 3 to rotate, the conveying auger 3 conveys the sludge, the sludge is gradually extruded by the conveying shaft of the conveying auger 3 during the conveying process in the conveying pipe 2, the water in the sludge is gradually extruded out and discharged from the drainage hole at the bottom of the conveying pipe 2, and finally enters the rack 1 for subsequent treatment, the sludge continues to be conveyed along with the conveying auger 3 and enters the shell 10; When the conveying auger 3 rotates, the mudguard 4 can be driven to rotate synchronously. When the mudguard 4 rotates, the crushing device 5 can be driven to rotate. When the mudguard 4 drives the crushing rod 51 to rotate to the protrusion 523, the crushing rod 51 drives the rotating wheel 511 to rotate along the arc surface 524 of the protrusion 523. At this time, the protrusion 523 pushes the crushing rod 51 to rotate away from the discharge passage, and the torsional spring 522 is compressed. With the gradual rotation of the rotating wheel 511 along the protrusion 523, the crushing rod 51 gradually rotates away from the discharge passage. When the rotating wheel 511 rotates away from the protrusion 523, the torsional spring 522 releases the elastic restoring force, drives the rotating shaft of the crushing rod 51 to rotate, and then drives the crushing rod 51 to rotate towards the discharge passage. The blocky sludge is crushed, and the smaller sludge is discharged from the hole at the bottom of the shell 10. With the crushing rod 51 passing through the plurality of protrusions 523 in turn, the crushing rod 51 is driven to rotate multiple times, so that the blocky sludge can be continuously crushed. The smaller sludge enters the discharge hopper 12 after passing through the hole at the bottom of the shell 10 for subsequent treatment, and the dewatering operation of the sludge is completed. When it is necessary to clean the sludge in the space formed by the conveying auger 3 close to the discharge hopper 12 and the conveying pipe 2, the driver 722 is started first. The output shaft of the driver 722 drives the sliding frame 721 to slide, and the sliding frame 721 drives the sliding sleeve 71 to slide. When the sliding sleeve 71 slides, the mudguard 4 can be driven to slide and adjust. When the mudguard 4 slides towards the shell 10, the mudguard 4 can drive the rotating gear 622 to move. At the same time, due to the meshing of the rotating gear 622 and the fixed rack 621, the rotating gear 622 rotates. The rotating gear 622 drives the crushing rod 51 to rotate, and the end of the crushing rod 51 away from the mudguard 4 rotates away from the shell 10. At the same time, when the mudguard 4 slides, the discharge passage between the mudguard 4 and the rack 1 becomes larger. At the same time, the crushing rod 51 drives the high-pressure nozzle 61 to rotate towards the position of the conveying auger 3 close to the discharge hopper 12. After the crushing rod 51 drives the high-pressure nozzle 61 to rotate towards the position of the conveying auger 3 close to the discharge hopper 12, the water supply member is started. The water supply member delivers washing water to the water storage cavity. The washing water enters the high-pressure nozzle 61 through the water supply pipe 63 and is sprayed out through the high-pressure nozzle 61. The position of the conveying auger 3 close to the discharge hopper 12 is washed. The sludge generated by the washing is discharged from the hole at the bottom of the shell 10.

[0052] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.

3. A sludge dewatering machine according to claim 2, characterized in that, The protrusion (523) is provided with an arc-shaped surface (524), which is inclined along the rotation direction of the mudguard (4) and away from the feed hopper (11).

4. A sludge dewatering machine according to claim 3, characterized in that, The crushing rod (51) has a rotating wheel (511) that is adapted to the arc surface (524) on the side near the protrusion (523).

5. A sludge dewatering machine according to claim 1, characterized in that, The mudguard (4) is slidably fitted to the conveying auger (3) along the central axis of the conveying pipe (2). A flushing device (6) is provided on the crushing rod (51). The flushing device (6) includes a high-pressure nozzle (61) for flushing the sludge on the conveying auger (3) near the discharge hopper (12), a water supply mechanism for supplying water to the high-pressure nozzle (61), and a rotating assembly (62) for driving the high-pressure nozzle (61) to rotate. The high-pressure nozzle (61) is provided on the crushing rod (51).

6. A sludge dewatering machine according to claim 5, characterized in that, The water supply mechanism includes a water supply pipe (63) for supplying water to the high-pressure nozzle (61) and a water supply assembly for supplying water to the water supply pipe (63), one end of which is connected to the high-pressure nozzle (61).

7. A sludge dewatering machine according to claim 6, characterized in that, The water supply assembly includes a water storage cavity disposed in the mudguard (4) and a water supply component for supplying water to the water storage cavity, and one end of the water supply pipe (63) is connected to the water storage cavity.

8. A sludge dewatering machine according to claim 1, characterized in that, The rotating assembly (62) includes a fixed rack (621) mounted on the frame (1) and a rotating gear (622) disposed on the crushing rod (51), the rotating gear (622) meshing with the fixed rack (621).

9. A sludge dewatering machine according to claim 5, characterized in that, The frame (1) is provided with a moving device (7), which includes a sliding sleeve (71) for driving the mudguard (4) to slide and a sliding assembly (72) for driving the sliding sleeve (71) to slide. The sliding sleeve (71) is rotatably engaged with the mudguard (4).

10. A sludge dewatering machine according to claim 9, characterized in that, The sliding assembly (72) includes a sliding frame (721) connected to the sliding sleeve (71) and a driver (722) for driving the sliding frame (721) to slide, the driver (722) being mounted on the frame (1).
