[0030] Referring toFigure 1 、 Figure 2 and Figure 3 As shown in FIGS. 1-6, a sludge drying machine easy to clean includes a drying box group 1 and a hot air fan group 7 connected with the drying box group 1. The drying box group 1 includes a box shell 11 and a sealed front cover 12 installed on the front end surface of the box shell 11 and fixedly connected with the box shell 11. A plurality of conveying wheel groups 2 are installed in the box shell 11. A plurality of cleaning assemblies 3 corresponding to the conveying wheel groups 2 are installed on the inner side surface of the sealed front cover 12. The cleaning assemblies 3 are rotationally connected with the sealed front cover 12. A driving rod 4 driving the synchronous rotation of all the cleaning assemblies 3 is installed on the outer side surface of the sealed front cover 12. An elastic support 5 supporting the driving rod 4 is also installed on the outer side surface of the sealed front cover 12. An electric cylinder 6 pressing down the driving rod 4 is fixedly installed on the elastic support 5. The hot air fan group 7 is installed outside the drying box group 1. The hot air fan group 7 blows hot air into the drying box in real time during the drying process, thereby heating and drying the sludge in the drying box. The drying box group 1 is designed in a structure that the box shell 11 cooperates with the sealed front cover 12, thereby ensuring that the box shell 11 is more stable during the processing. The hot air can better heat and dry the sludge. The sealed front cover 12 can be directly disassembled during maintenance, thereby better cleaning and maintaining the inside of the box shell 11. A plurality of conveying wheel groups 2 are installed in the box shell 11. The conveying wheel groups 2 reciprocally move downward during the drying process, thereby ensuring that the drying operation is realized during the movement. A plurality of cleaning assemblies 3 corresponding to the conveying wheel groups 2 are installed on the inner side surface of the sealed front cover 12, thereby ensuring that the conveying wheel groups 2 are cleaned by the cleaning assemblies 3 during use. The driving rod 4 ensures that the cleaning assemblies 3 are rotated during use. The cleaning assemblies 3 are flipped down when cleaning is needed and flipped up when cleaning is not needed, thereby not affecting the normal use of the conveying wheel groups 2. The elastic support 5 ensures that the driving rod 4 is supported and moves upward, thereby ensuring that the driving rod 4 automatically flips up the cleaning assemblies 3. The electric cylinder 6 presses down the driving rod 4 when cleaning is needed, thereby flipping down the cleaning assemblies 3 by the driving rod 4. A filling port 111 is formed in the upper end surface of the box shell 11. A discharge port 112 is formed in the side surface of the box shell 11. A flow guide shell 113 corresponding to the discharge port 112 is fixedly installed in the box shell 11. The sludge to be processed can stably enter the drying box through the filling port 111. The dried sludge is better discharged through the discharge port 112 and the flow guide shell 113.

[0031] Referring to Figure 2As shown, the conveying wheel set 2 comprises forward conveying belts 21 and reverse conveying belts 22 which are spaced apart. By designing the conveying wheel set 2 as a structure in which the forward conveying belts 21 and the reverse conveying belts 22 are matched, the sludge can be moved back and forth in the drying box by the conveying belts in use, and the drying operation by hot air is thus more convenient.

[0032] With reference to Figure 3 and Figure 6 As shown, the cleaning assembly 3 comprises a shaft 31 and a scraper 32, the shaft 31 is rotatably installed on the sealing front cover 12, and the scraper 32 is fixedly sleeved on the shaft 31. By designing the cleaning assembly 3 as a structure in which the shaft 31 and the scraper 32 are matched, the scraper 32 can be rotatably installed on the sealing front cover 12 by the shaft 31 in use, and the use state can be conveniently adjusted by rotating the shaft 31 in use. The outer end of the shaft 31 is fixedly installed with a concave frame plate 311, and the head of the concave frame plate 311 is further installed with a cylindrical rod 312 which is fixedly connected with the concave frame plate 311. By fixedly installing the concave frame plate 311 on the outer end of the shaft 31 and fixedly installing the cylindrical rod 312 on the concave frame plate 311, the cylindrical rod 312 can be matched with the driving rod 4, so as to conveniently rotate the shaft 31 under the driving of the driving rod 4.

[0033] With reference to Figure 4 , Figure 5 and Figure 7 As shown, the driving rod 4 comprises a middle rod 41 and a side frame 42 for installing the cylindrical rod 312, the lower end surface of the middle rod 41 is fixedly installed with a horizontal plate 411, the side frame 42 is installed on both sides of the middle rod 41, and the side frame 42 is fixedly connected with the middle rod 41. By designing the driving rod 4 as a structure in which the middle rod 41 and the side frame 42 are matched, the side frame 42 can be clamped on the cylindrical rod 312 in use, and the shaft 31 can be rotated by lifting the side frame 42. The middle rod 41 is provided with a limiting slide 412 which is integrally formed with the middle rod 41, and the outer side surface of the sealing front cover 12 is provided with a longitudinal sliding groove 121 for slidingly installing the limiting slide 412. By providing the limiting slide 412 on the middle rod 41, the middle rod 41 can be stably installed in the longitudinal sliding groove 121 when needed, so as to stably lift and slide.

[0034] With reference to Figure 5As shown, the elastic support 5 comprises a frame 51 fixedly installed on the outer side of the sealing front cover 12 and a supporting spring 52 fixedly installed between the frame 51 and the horizontal plate 411. By designing the elastic support 5 as the structure that the frame 51 and the supporting spring 52 are matched, the supporting spring 52 can be used to support the middle rod 41 in a symmetrical manner when the elastic support 5 is used, so that the driving rod 4 can drive the cleaning assembly 3 to overturn upward when no external force is applied.

[0035] In the embodiment, the sludge is put into the filler port during actual processing, and then the sludge enters the conveying wheel set in the box shell, is first transmitted through the forward conveying belt, falls onto the reverse conveying belt at the lower end, and then is transmitted on the reverse conveying belt and can fall onto the forward conveying belt at the lower end. In the process of repeatedly moving the sludge, the sludge can be rapidly dried by the hot air supplied by the hot air set, and the dried sludge can be stably discharged from the guide shell of the discharge port. When the conveying wheel set needs to be cleaned after processing is completed, the electric cylinder can be started to press down the driving rod, so that the driving rod drives the cleaning assembly to overturn, and the scraper is supported on the conveying belt. In this way, the conveying belt can be started to clean the surface thereof, and the scraper is turned over after cleaning, so that the conveying belt can discharge the impurities after cleaning.

[0036] The above is the preferred embodiment of the utility model, and the person skilled in the art of the utility model can also change and modify the above embodiment. Therefore, the utility model is not limited to the above specific embodiments, and any obvious improvement, replacement or modification made by the person skilled in the art on the basis of the utility model belongs to the protection scope of the utility model.
