[0029] Specifically describe the specific settings and functions of its docking device 6 and auxiliary device 7 below.

[0030] Refer to Figure 2 , Figure 3 and Figure 4 As shown, in this implementation: The docking device 6 includes a fixed column 61 and a connecting column 65. One end of the fixed column 61 is fixedly connected to the conveyor belt 8. One end of the fixed column 61 is fixedly connected to a fixed block 62. A slot 68 is provided on the inner wall of the fixed block 62. A plug 67 is fixedly connected to the arc surface of the connecting column 65 corresponding to the position of the slot 68. The surface of the plug 67 is slidably connected to the inner wall of the slot 68. A docking block 63 is slidably connected to the arc surface of the connecting column 65. The surface of the docking block 63 near one end of the fixed column 61 is slidably connected to the inner wall of the fixed block 62. A rotating ring 64 is threadedly connected to the arc surface of the connecting column 65. One side of the rotating ring 64 abuts against one side of the docking block 63. The two connecting columns 65 are fixedly connected to the same tooth rake 5 at the ends close to each other. By providing the docking device 6, the structural complexity between the tooth rake 5, the transmission device 4, and the chain is simplified, achieving convenient and rapid replacement of the tooth rake 5 by the operator and improving work efficiency. A number of friction grooves 69 are provided on the arc surface of the rotating ring 64. The number of friction grooves 69 is evenly distributed on the arc surface of the rotating ring 64, increasing the friction force between the hand and the rotating ring 64 and preventing the phenomenon of hand slipping during rotation. The connecting column 65 is made of stainless steel, and the rotating ring 64 is made of stainless steel. The effects achieved by the above components are: reducing the oxidation efficiency of the connecting column 65 and the rotating ring 64 and preventing them from rusting, resulting in problems with difficult rotation. An extrusion ring 66 is slidably connected to the arc surface of the connecting column 65. One side of the extrusion ring 66 abuts against the side wall of the docking block 63. The extrusion ring 66 is an elastic rubber ring. The rotating ring 64 gives a continuous elastic force to the docking block 63 through extrusion, thereby increasing the friction force between the rotating ring 64 and the docking block 63 and preventing loosening caused by vibration and other reasons.

[0031] Refer to Figure 5As shown in the figure, in this embodiment: The auxiliary device 7 includes a rotating frame 71, the rotating frame 71 is fixedly connected to the side surface of the collection box 2, the inner wall of the rotating frame 71 is rotatably connected with a rotating plate 72, a screw rod 74 is threadedly penetrated through the inner wall of one end of the rotating plate 72 away from the rotating frame 71, one end of the screw rod 74 is rotatably connected with a limiting block 76, a limiting frame 77 is fixedly connected to the side surface of the support frame 1 corresponding to the position of the limiting block 76, and the inner wall of the limiting frame 77 is slidably connected with the surface of the limiting block 76. By providing the auxiliary device 7, during the process of collecting solid garbage in the sewage, the phenomenon that the collection box 2 slides and deviates is avoided, preventing the garbage from leaking outside the collection box 2, and effectively collecting the garbage. A limiting rod 75 is slidably penetrated through the inner wall of one end of the rotating plate 72 away from the rotating frame 71, one end of the limiting rod 75 is fixedly connected with the limiting block 76, and the limiting rod 75 prevents the limiting block 76 from rotating. The cross-section of the rotating frame 71 is in a "U" shape, and a torsion spring 73 is sleeved on the inner wall arc surface of the rotating frame 71. The two ends of the torsion spring 73 are respectively fixedly connected with the rotating frame 71 and the rotating plate 72. The torsional force generated by the torsion spring 73 can squeeze and limit the position of the rotating plate 72, thereby avoiding the shaking of the position of the rotating plate 72.

[0032] The working principle of a sewage treatment grille machine provided by the present utility model is as follows. During the process of using the sewage treatment grille machine to process solid impurities in the sewer pipe for a long time, the tooth rake 5 is prone to wear and even breakage, and needs to be replaced in time. When the tooth rake 5 needs to be replaced, first turn off the transmission device 4, rotate the rotating ring 64 on the arc surface of the connecting column 65 to release the extrusion and fixing effect on the docking block 63, then slide the docking block 63 out of the inner wall of the fixed block 62, lift the tooth rake 5 upward, and the plug 67 on the arc surface of the connecting column 65 driven by the tooth rake 5 slides out of the slot 68, and then install a new tooth rake 5. Align the plug 67 on the arc surface of the connecting column 65 and slide it into the slot 68, then slide the docking block 63 into the inner wall of the fixed block 62, and then rotate the rotating ring 64. The rotating ring 64 gives a continuous elastic force to the docking block 63 through the extrusion of the extrusion ring 66, thereby increasing the friction force between the rotating ring 64 and the docking block 63, preventing loosening caused by vibration and other reasons, and realizing the fixing effect on the tooth rake 5.

[0033] When treating sewage, first move the collection box 2 to the discharge port of the conveying frame 3. To prevent the collection box 2 from deviating during the process of collecting garbage, it needs to be fixed and limited. First, rotate the rotating plate 72 towards the direction of the limiting frame 77. During this process, the torsional force generated by the torsion spring 73 can squeeze and limit the position of the rotating plate 72, thereby avoiding the shaking of the position of the rotating plate 72. Then rotate the screw rod 74, and the screw rod 74 drives the limiting block 76 to slide towards the inner wall of the limiting frame 77. During this process, the limiting rod 75 prevents the limiting block 76 from rotating. When the limiting block 76 slides into the inner wall of the limiting frame 77, the fixing effect on the collection box 2 is realized.

[0034] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
