The ball valve 13 is rotatably connected to the discharge pipe 7, and the groove wheel 136 is fixedly sleeved on the front side of the shaft of the ball valve 13. The support plate 132 is symmetrically fixedly connected to the top of the shell 1, and the left and right support plates 132 are respectively located in the left and right fixed shells 4. The upper part of the support plate 132 is rotatably connected to the guide shaft 133, and the guide disk 134 is fixedly sleeved on the guide shaft 133. The guide disk 134 contacts the outer side of the groove wheel 136. The contact rod 135 is fixedly connected to the eccentric position of the front side of the guide disk 134. The contact rod 135 is located in the groove of the groove wheel 136. When the contact rod 135 rotates, the contact rod 135 can drive the groove wheel 136. 6 rotation, an intermittent rotating assembly is arranged between the guide shaft 133 and the housing 1, and when the intermittent rotating assembly is in operation, the intermittent rotating assembly can drive the guide shaft 133 to rotate intermittently; the intermittent rotating assembly includes a vertical rod 131, a missing gear 1311 and a guide bevel gear 1312, the front ends of the guide shafts 133 on the left and right sides are fixedly sleeved with the guide bevel gear 1312, the top of the outer top of the housing 1 is symmetrically rotated with the vertical rod 131, the vertical rod 131 is located in the fixed shell 4, the vertical rods 131 on the left and right sides are driven by the electric rotating shaft 81 through the synchronous belt assembly, the top ends of the vertical rods 131 on the left and right sides are respectively connected with the inner ends of the rotating rods 11 on the left and right sides through the bevel gear transmission, the upper part of the vertical rod 131 is fixedly sleeved with the missing gear 1311, and the missing gear 1311 is meshed with the guide bevel gear 1312.

[0032] First, the fixing seat 3 is installed on the arm connection of the excavator, and the three-way pipe 5 is externally connected to the container for discharging the curing agent, and then the electric shaft 81 is started to rotate, and the electric shaft 81 drives the spiral stirring shafts 82 on the left and right sides to rotate through the bevel gear assembly 8. At the same time, the rotation of the electric shaft 81 drives the vertical rod 131 to rotate through the synchronous belt assembly. The rotation of the vertical rod 131 drives the missing gear 1311 to rotate, and the missing gear 1311 rotates and meshes with the guide bevel gear 1312. The missing gear 1311 drives the guide bevel gear 1312 to rotate, and the guide bevel gear 1312 drives the guide shaft 133 to rotate, and the guide shaft 133 drives the guide plate 134 to rotate, and the guide plate 134 rotates to drive the contact rod 135 to rotate, and the contact rod 135 rotates to drive the groove wheel 136 to rotate ninety degrees , the groove wheel 136 drives the ball valve 13 to rotate 90 degrees to open, the missing gear 1311 continues to rotate and disengages from the guide bevel gear 1312, the guide bevel gear 1312 stops driving the guide plate 134 to rotate, and the guide plate 134 stops driving the contact rod 135 to rotate. When the missing gear 1311 rotates and engages with the guide bevel gear 1312 again, the missing gear 1311 drives the guide bevel gear 1312 to rotate once, the guide bevel gear 1312 drives the guide plate 134 to rotate through the guide shaft 133, and the guide plate 134 drives the contact rod 135 to rotate. At this time, the contact rod 135 rotates and disengages from the groove wheel 136, and the groove wheel 136 will not drive the ball valve 13 to rotate. This is repeated. When the contact rod 135 rotates for the fourth time, the contact rod 135 drives again. The groove wheel 136 rotates, and the groove wheel 136 drives the ball valve 13 to rotate ninety degrees to complete the closing. In this way, the ball valve 13 can be opened and closed by intermittent rotation. At the same time, the rotation of the vertical rod 131 also drives the rotating rod 11 to rotate through the bevel gear transmission, and the rotating rod 11 drives the hard brush 12 to rotate. The hard brush 12 rotates and contacts with the rotating ring 10. The rotating rod 11 also drives the rotating ring 10 to rotate through the synchronous belt assembly. The rotation of the rotating ring 10 drives the spiral scraper 101 to rotate. Then the excavator is started to drive the machine arm to move. The movement of the machine arm drives the fixed seat 3 to move. The fixed seat 3 moves through the shell 1 to drive the spiral stirring shaft 82 to rotate, so that the spiral stirring shaft 82 moves into the sludge. The spiral stirring shaft 82 rotates to stir the sludge, and at the same time, the curing agent is discharged into the three-way pipe 5. The curing agent in the through pipe 5 is discharged into the expansion joint 6. When the ball valve 13 is in the closed state, the curing agent in the expansion joint 6 is blocked and cannot be sprayed out, so that the curing agent in the expansion joint 6 continues to increase. Then, when the ball valve 13 is opened, due to the effect of the expansion joint 6, the expansion structure violently discharges the curing agent into the discharge pipe 7, and the discharge pipe 7 violently sprays the curing agent. The sprayed curing agent contacts the stirred sludge. In this way, the violent spraying of the curing agent can improve the discharge efficiency, thereby improving the curing efficiency. The spiral stirring shaft 82 stirs the sludge and the curing agent together. Under the action of the curing agent, the sludge is solidified. When the ball valve 13 is closed again, the curing agent stops being discharged into the discharge pipe 7, and the curing agent in the expansion joint 6 continues to increase, and this is repeated.The curing agent is intermittently and violently ejected to complete the solidification of the sludge. When the sludge is in the process of solidification, part of the sludge will enter the inner wall of the nozzle of the discharge pipe 7 and adhere to it. The spiral scraper 101 can scrape off the sludge attached to the inner wall of the nozzle of the discharge pipe 7 to prevent the sludge from adhering to the inner wall of the nozzle of the discharge pipe 7 and causing blockage to affect the ejection of the curing agent, thereby improving the efficiency of sludge solidification. The scraped sludge is pushed out by the spiral scraper 101, and the pushed out sludge is discharged through the rotating ring 10. At the same time, the rotation of the bristle brush 12 can remove the sludge remaining on the rotating ring 10 to prevent the sludge remaining on the rotating ring 10 from affecting the discharge of the curing agent, thereby ensuring the smooth discharge of the curing agent, and the excavator can be driven. The movement causes the spiral stirring shaft 82 to move through the curing agent to cure all the sludge. When all the sludge is cured, the curing agent is stopped from being discharged into the three-way pipe 5, and the discharge pipe 7 stops discharging the curing agent. Then the excavator is operated to drive the shell 1 to move through the machine arm, so that the shell 1 drives the spiral stirring shaft 82 to move and break away from the cured sludge. The electric shaft 81 is turned off, and the electric shaft 81 stops driving the spiral stirring shaft 82 to rotate through the bevel gear assembly 8. The electric shaft 81 also stops driving the vertical rod 131 to rotate, the ball valve 13 stops intermittent rotation, the spiral scraper 101 stops rotating, the three-way pipe 5 is separated from the container containing the curing agent, and then the fixing seat 3 is removed from the machine arm of the excavator.

[0033] See also Figure 7 and Figure 8 As shown, the sludge solidification treatment device also includes a knocking assembly installed on the rotating rod 11, and the knocking assembly includes a cross rod 14, a knocking rod 141 and a torsion spring 142. The left and right rotating rods 11 are fixedly mounted with cross rods 14, and the cross rod 14 corresponds to the discharge pipe 7. The four ends of the cross rod 14 are rotatably connected with the knocking rods 141. When the knocking rod 141 rotates and contacts the discharge pipe 7, the knocking rod 141 can knock and vibrate the discharge pipe 7. A torsion spring 142 is connected between the knocking rod 141 and the cross rod 14.

[0034] When the electric shaft 81 starts to rotate, the rotating rod 11 rotates to drive the cross rod 14 to rotate, and the cross rod 14 drives the knocking rod 141 to rotate. When the knocking rod 141 rotates and contacts the discharge pipe 7, the knocking rod 141 knocks and vibrates the discharge pipe 7, and the discharge pipe 7 vibrates the sludge attached to the inner wall of the nozzle. The spiral scraper 101 rotates to scrape and discharge the vibrating sludge. As the knocking rod 141 continues to rotate, the discharge pipe 7 pushes the knocking rod 141 to swing, and the torsion spring 142 is compressed. When the knocking rod 141 continues to rotate and disengages from the discharge pipe 7, due to the action of the torsion spring 142, the knocking rod 141 swings and resets. This is repeated, so that the knocking rod 141 can continuously knock and vibrate the discharge pipe 7, so that the sludge attached to the inner wall of the nozzle of the discharge pipe 7 is continuously vibrated and scraped off. When the electric shaft 81 is closed, the rotating rod 11 stops driving the cross rod 14 to rotate, the cross rod 14 stops driving the knocking rod 141 to rotate, and the knocking rod 141 stops knocking and vibrating the discharge pipe 7. In this way, the sludge attached to the inner wall of the nozzle of the discharge pipe 7 can be scraped off better, thereby improving the effect of scraping off the sludge.

[0035] See also Fig. 9 As shown, the sludge solidification treatment device also includes a brush plate 15 and a pull rod 16. The brush plates 15 are rotatably connected to the front and rear side surfaces outside the shell 1. When the brush plate 15 swings and contacts the spiral stirring shaft 82, the brush plate 15 can remove the sludge remaining on the spiral stirring shaft 82. The pull rods 16 are fixedly connected to the tops of the brush plates 15 on the front and rear sides.

[0036] See also Fig.10 As shown, the sludge solidification treatment device also includes a stirring frame 17. The stirring frame 17 is fixedly connected to the bottom end of the electric rotating shaft 81. When the stirring frame 17 rotates, the stirring frame 17 can stir the sludge.

[0037] When the spiral stirring shaft 82 moves and is out of contact with the sludge, the three-way pipe 5 is connected to an external water source, and water is discharged into the three-way pipe 5, so that the discharge pipe 7 intermittently sprays water, and the water is sprayed on the spiral stirring shaft 82, and the water washes and removes the sludge attached to the spiral stirring shaft 82. At this time, the pull rod 16 is pulled to drive the brush plate 15 to swing 180 degrees, and the brush plate 15 swings 180 degrees to contact the spiral stirring shaft 82. The brush plate 15 removes the sludge on the spiral stirring shaft 82 through water. When the sludge on the spiral stirring shaft 82 is cleaned, stop discharging water into the three-way pipe 5, the discharge pipe 7 stops discharging water, separate the three-way pipe 5 from the water source, and pull the pull rod 16 to drive the brush plate 15 to swing 180 degrees in the opposite direction to reset. In this way, a large amount of sludge attached to the spiral stirring shaft 82 can be prevented from affecting subsequent use, thereby ensuring the use effect of the spiral stirring shaft 82.

[0038] When the electric shaft 81 is turned on, the electric shaft 81 drives the stirring frame 17 to rotate, and the rotation of the stirring frame 17 can stir the sludge, so that the sludge and the curing agent are mixed together, so that the sludge is cured. When the electric shaft 81 is turned off, the electric shaft 81 stops driving the stirring frame 17 to rotate. In this way, the sludge can be further stirred to complete the curing process, thereby improving the stirring effect of the sludge.

[0039] A solidification treatment method for a sludge solidification treatment device comprises the following steps: S1, installation, connecting the fixing base 3 to the arm of the excavator, and connecting the feeding end of the three-way pipe 5 to the container containing the curing agent; S2, start, start the electric shaft 81 and drive the spiral stirring shaft 82 to rotate through the bevel gear assembly 8, the electric shaft 81 also drives the vertical rod 131 to rotate through the synchronous belt assembly, so that the ball valve 13 rotates intermittently to complete opening and closing, and also causes the spiral scraper 101 to rotate, and then discharges the curing agent into the three-way pipe 5, and the curing agent in the three-way pipe 5 is discharged into the expansion joint 6. When the ball valve 13 is opened, the curing agent is discharged into the discharge pipe 7, and the discharge pipe 7 sprays the curing agent; S3, solidification treatment, when the spiral stirring shaft 82 moves and contacts the sludge, the spiral stirring stirs the sludge, and the spiral stirring shaft 82 solidifies the sludge through the curing agent. At the same time, the spiral scraper 101 rotates to scrape off and discharge the sludge attached to the inner wall of the nozzle of the discharge pipe 7.
