A material dropping mechanism and a material pressing mechanism located above the conveyor belt are respectively fastened to both ends of the processing table. An anti-clogging mechanism connected to the processing table is provided between the material dropping mechanism and the material pressing mechanism. The anti-clogging mechanism includes a connecting shaft located above the conveyor belt and rotatably connected to the processing table. A third motor is coaxially connected to one end of the connecting shaft, and multiple levers are circumferentially connected to the outer wall of the connecting shaft.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 5 This utility model provides a technical solution: a clog-resistant feeding device for a mud press, including a processing table 5, on which a conveyor belt 17 driven by a second motor 4 is installed. A material discharge mechanism and a material pressing mechanism located above the conveyor belt 17 are respectively fastened to both ends of the processing table 5, and an anti-clogging mechanism connected to the processing table 5 is provided between the material discharge mechanism and the material pressing mechanism. The material discharge mechanism includes a material discharge box 20 fastened to the top of the processing table 5 and located above the conveyor belt 17. Parallel spiral blades 26 are rotatably connected to the discharge port of the material discharge box 20, and the top of the spiral blades 26 is driven by a first motor 2. Figure 3 As shown, the spiral blades 26 can rotate and stir the falling sludge, ensuring the normal feeding of the sludge and effectively preventing the sludge from clogging in the feed box 20. In addition, the spiral blades 26 can also crush impurities.

[0023] like Figure 2 , 3As shown, the pressing mechanism includes a mounting box 14 that is tightly attached to the top of the processing table 5 and located above the conveyor belt 17. The mounting box 14 is connected to a mounting frame 18 via a telescopic mechanism 15, and a pressure roller 23 is rotatably connected inside the mounting frame 18. One end of the pressure roller 23 is driven by a fourth motor 7. In actual use, a support seat is set at the bottom of the conveyor belt 17. During the sludge pressing operation, the pressure roller 23 and the support seat work together to effectively press and dewater the sludge. The telescopic mechanism 15 is one of an electric pusher, a pneumatic cylinder, or a hydraulic cylinder. To ensure that the mounting frame 18 can move up and down smoothly, multiple guide rods 16 that penetrate the mounting box 14 are vertically connected to the top of the mounting frame 18.

[0024] like Figure 3 , 4 As shown in Figure 5, the anti-blocking mechanism includes a connecting shaft 9 located above the conveyor belt 17 and rotatably connected to the processing table 5. A second support 21 is symmetrically connected to the top of the processing table 5 along the conveyor belt 17, and the connecting shaft 9 is rotatably connected between the second supports 21. A third motor 6 is coaxially connected to one end of the connecting shaft 9, and multiple levers 8 are circumferentially connected to the outer wall of the connecting shaft 9. Meanwhile, a material collection hopper 10 parallel to the connecting shaft 9 is provided on one side. A first support 11 is symmetrically connected to the top of the processing table 5 along the conveyor belt 17, and the material collection hopper 10 is rotatably connected between the first supports 11. Both ends of the material collection hopper 10 are rotatably connected to the processing table 5, and multiple openings 22 are opened on the top side of the material collection hopper 10 near the connecting shaft 9.

[0025] The third motor 6 drives multiple levers 8 and connecting shaft 9 to rotate simultaneously. When the levers 8 rotate above the conveyor belt 17, they agitate the sludge located at the top of the conveyor belt 17, which can clean out the impurities inside the sludge and drive the impurities to the opening 22 on the collecting hopper 10. When the levers 8 move into the opening 22, the impurities can be scraped into the collecting hopper 10, thus cleaning the impurities inside the sludge and avoiding clogging of the device.

[0026] Meanwhile, in order to achieve continuous contact between the hopper 10 and the lever 8, a positioning rod 13 is tightly fastened on the side of the hopper 10 away from the opening 22. A return spring 12 is rotatably connected to the positioning rod 13, and the other end of the return spring 12 is fixedly connected to the side wall of the first support 11. A limit plate 19 is connected to the end of the positioning rod 13, and a sleeve 3 is sleeved on the positioning rod 13. One end of the return spring 12 is fixedly connected to the sleeve 3. Under the elastic force of the return spring 12, the hopper 10 can be rotated back and forth, so that the rotating lever 8 can repeatedly contact the hopper 10, thereby achieving continuous treatment of impurities on the lever 8. This not only has a simple structure but also improves the cleaning efficiency and effectively prevents clogging.

[0027] In summary, the anti-clogging sludge press feeding device has a limiting side plate 1 symmetrically arranged on the top of the processing table 5 along the conveyor belt 17 during use. The end of the limiting side plate 1 extends to the top of the conveyor belt 17 to prevent sludge from falling from the top of the conveyor belt 17 during transportation. A liquid collection tank 24 located below the conveyor belt 17 is also tightly fixed at the bottom of the processing table 5. A drain pipe 25 is connected to one end of the liquid collection tank 24 to collect the water pressed out during the sludge pressing process.
