Detailed Embodiment

[0018] The following describes the preferred embodiments of the present utility model in detail with reference to the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.

[0019] Please refer toFigure 1 and Figure 2 A high-wear-resistant disc dryer rake knife, comprising a rotating rod 1. A connecting sleeve 4 is fixedly connected to the outside of the rotating rod 1. Positioning holes 5 are provided on the side walls of multiple connecting sleeves 4. The positioning holes 5 cooperate with positioning rods 8 to facilitate the positioning of the protective sleeve 6. Multiple connecting sleeves 4 are fixedly connected with stirring rods 2 in a circular shape on the outside. Protective sleeves 6 are arranged outside multiple stirring rods 2. The protective sleeves 6 are symmetrically arranged and are in contact with the side walls of the stirring rods 2, which can protect the stirring rods 2, improve the service life of the stirring rods 2, and avoid wear. Only the protective sleeve 6 needs to be replaced, which is more convenient during use. Two mounting plates 7 are fixedly connected to the lower end of the protective sleeve 6, and positioning rods 8 are fixedly connected to the side walls of the two mounting plates 7.

[0020] As Figure 3 and Figure 4 shown, a scraping plate 3 is fixedly connected to the upper end of the stirring rod 2. The scraping plate 3, the rotating rod 1 and the stirring rod 2 form a dryer rake knife. A fixing plate 9 and a housing 10 are fixedly connected to the side wall of the protective sleeve 6. Two inserting rods 11 are fixedly connected to the side wall of the fixing plate 9. The inserting rods 11 cooperate with the inside of the housing 10, and the position of the inserting rods 11 is fixed by a fixing rod 12, thereby fixing the protective sleeve 6. Two limiting plates 17 are slidably connected to the middle of the housing 10. Fixing rods 12 are fixedly connected to the side walls of the two limiting plates 17 for fixing the inserting rods 11. One end of the fixing rod 12 passes through the middle of the inserting rod 11 and extends to the outside. A threaded rod 15 is rotatably connected to the middle of the housing 10. The external threads of the threaded rod 15 are symmetrically arranged, so that two threaded blocks 18 move towards each other. Two threaded blocks 18 are threadedly connected to the outside of the threaded rod 15. Connecting members 16 are arranged on both sides of the two threaded blocks 18 and the side walls of the limiting plates 17. The connecting members 16 on the side walls of the limiting plates 17 slide inside the limiting plates 17. A supporting rod 13 is rotatably connected to the side wall of the connecting member 16. A nut 14 is arranged on the side wall of the housing 10 for driving the threaded rod 15 to rotate, which is convenient for disassembling and replacing the protective sleeve 6. The side wall of the nut 14 is fixedly connected to one end of the threaded rod 15.

[0021] When the utility model is in use, the protective sleeve 6 is installed outside the stirring rod 2. The position of the protective sleeve 6 is positioned by the cooperation of the positioning rod 8 and the positioning hole 5, and the inserting rod 11 extends into the inside of the housing 10. The nut 14 drives the threaded rod 15 to rotate. During the rotation, the two threaded blocks 18 move towards each other. During the movement, the supporting rod 13 pushes the limiting plate 17 to move, so that the fixing rod 12 passes through the middle of the inserting rod 11, thereby fixing the protective sleeve 6 and keeping the protective sleeve 6 stable, which is convenient for protecting the stirring rod 2, improving the service life of the stirring rod 2, and avoiding wear.

[0022] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
