DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] See also Figure 1-4 The utility model provides a peripheral transmission suction and scraping machine for sewage treatment, including a sedimentation tank 1, which also includes a maintenance ladder 2. The maintenance ladder 2 is fixed to the top side wall of the sedimentation tank 1, and a side wall of one side of the maintenance ladder 2 is rotatably connected with a transmission shaft 3. A servo motor 4 is fixed to the top side wall of the maintenance ladder 2, and a transmission shaft 3 is coaxially fixed to one end of the output shaft of the servo motor 4. A scraper arm 5 is fixed to one end of the transmission shaft 3, and an auxiliary component 6 is arranged on one side of the scraper arm 5. A flow stabilizer 7 is tightly sleeved on the outer surface of the transmission shaft 3. Through the arrangement of the flow stabilizer 7, it can be ensured that the transmission shaft 3 is always in a stable operating state to work, and through the arrangement of the maintenance ladder 2, it is convenient for staff to inspect the working state of the drive device of the device and the daily maintenance of various components.

[0026] Further Figure 3 and Figure 4As shown, it is worth specifically explaining that the auxiliary component 6 includes a rotating shaft 61, and a plurality of rotating shafts 61 are provided. The plurality of rotating shafts 61 are equidistantly distributed and rotatably connected to the side wall of one side of the scraper arm 5. A scraper plate 62 is tightly sleeved on the outer surface of the rotating shaft 61, and one side of the scraper plate 62 contacts the inner side of the sedimentation tank 1; a transmission ring 63, and two transmission rings 63 are provided. The two transmission rings 63 are symmetrically distributed and slidably connected to the side wall of one side of the scraper arm 5, and a plurality of teeth 64 equidistantly distributed are fixed on the inner side wall of the transmission ring 63, and a spur gear is tightly sleeved on the outer surface of the rotating shaft 61. 65, the spur gear 65 is meshed with the tooth 64, and two symmetrically distributed waterproof cylinders 66 are fixed to the side wall of one side of the scraper arm 5, and the output end of the waterproof cylinder 66 is fixed to the side wall of one side of the transmission ring 63. Through the setting of the auxiliary component 6, the angle position of the scraper plate 62 can be adjusted according to the amount of sludge in the sedimentation tank 1, which greatly improves the sludge scraping effect in the sedimentation tank 1 and has good adaptability. Compared with the traditional scraper plate 62, which is inconvenient to adjust the angle position, this device can be suitable for scraping work with various sludge amounts and has strong practicality.

[0027] Further Figure 2 and Figure 4 As shown, it is worth explaining in detail that a plurality of equidistantly distributed grating plates 15 are fixed to the side wall of one side of the scraper arm 5, and the grating plates 15 are located on both sides of the transmission shaft 3. By greatly lifting the scraper arm 5, better stability is guaranteed during operation, thereby reducing shaking damage.

[0028] This solution has the following working process: when it is necessary to remove the sludge in the sewage sedimentation tank 1, the servo motor 4 is driven to make the transmission shaft 3 rotate synchronously, driving the scraper arm 5 to operate synchronously, thereby driving the scraper plate 62 to operate synchronously, and the scraper plate 62 scrapes the sludge at the bottom of the sedimentation tank 1, so that the sludge is moved toward the center of the sedimentation tank 1 under the scraping force of the scraper plate, thereby achieving the purpose of sludge treatment. When it is necessary to adjust the angular position between the scraper plate 62 and the scraper arm 5, the waterproof cylinder 66 is driven to make the transmission ring 63 move synchronously, driving the teeth 64 to move synchronously, and utilizing the meshing transmission effect between the teeth 64 and the spur gear 65, the rotating shaft 61 is forced to rotate, thereby driving the scraper plate 62 to flip, thereby achieving the purpose of adjusting the angle of the scraper plate 62.

[0029] According to the above working process, it can be known that: through the setting of the auxiliary component 6, the angle position of the scraper plate 62 can be adjusted according to the amount of sludge in the sedimentation tank 1, which greatly improves the scraping effect on the sludge in the sedimentation tank 1, and has good adaptability. Compared with the traditional scraper plate 62, which is inconvenient to adjust the angle position, this device can be suitable for scraping work with various sludge amounts, and has strong practicality. By installing the ring 8 and the connecting steel cable a10, the stability of the scraper arm 5 during operation is greatly improved, avoiding the situation where the scraper arm 5 is shaken or even damaged due to excessive water pressure during operation. The scraper arm 5 and the transmission shaft 3 are under too little pressure, which has better security.

By setting the mounting ring 8 and the connecting steel cables a10, the stability of the scraper arm 5 during operation is greatly improved, and the situation that the scraper arm 5 is shaken or even damaged due to excessive water pressure during operation is avoided. The scraper arm 5 and the transmission shaft 3 are subjected to too little pressure, and have better security.

[0031] Further Figure 2 As shown, it is worth explaining in detail that two symmetrically distributed connecting steel cables b11 are fixed between the stabilizing rod 9 and the grating plate 15. The connecting steel cables b11 are located directly above the connecting steel cables a10. Through the setting of the connecting steel cables b11, the stability of the stabilizing rod 9 in the longitudinal section can be effectively improved, thereby reducing the pressure generated by the stabilizing rod 9 during operation.

[0032] Further Figure 4 As shown, it is worth explaining in detail that one side of the scraper blade 62 is provided with a chamfered inclined surface, two symmetrically distributed guide rods 12 are fixed to the side wall of one side of the transmission ring 63, and a plurality of symmetrically distributed mounting sleeves 13 are fixed to the top side wall of the scraper arm 5. The guide rod 12 and the mounting sleeve 13 are internally slidably penetrated, and the guide rod 12 slides in the mounting sleeve 13, which not only plays a guiding and limiting role for the transmission ring 63, but also can improve the stability of the transmission ring 63 when moving.

[0033] Further Figure 3 As shown, it is worth explaining in detail that the guide rod 12 is located on both sides of the waterproof cylinder 66, and a limiting ring 14 is fixed at one end of the guide rod 12. The setting of the limiting ring 14 plays a role in limiting the guide rod 12 to prevent the guide rod 12 from moving too far and falling off.

[0034] In summary: through the setting of the stabilizer tube 7, it can be ensured that the transmission shaft 3 is always in a stable operating state to work, and through the setting of the maintenance ladder 2, it is convenient for the staff to inspect the working state of the driving device of the device and the daily maintenance of each component, and by greatly lifting the scraper arm 5, it has a better stability guarantee during operation, thereby reducing the shaking damage, and through the setting of the connecting steel cable b11, the stability of the stabilizing rod 9 in the longitudinal section can be effectively improved, thereby reducing the pressure generated by the stabilizing rod 9 during operation, and through the guide rod 12 sliding in the mounting sleeve 13, it can not only play a guiding and limiting role for the transmission ring 63, but also can improve the stability of the transmission ring 63 when moving, and through the setting of the limiting ring 14, it plays a limiting role on the guide rod 12 to prevent the guide rod 12 from moving too far and falling off.
