[0035] See also Figure 3 The collecting assembly 7 includes a circular plate 71 for connecting various components, and the push rod 62 is fixedly connected thereto. A scraper ring 72 is provided at the lower portion of the circular plate 71 for collecting materials adhered to the inner wall of the sublimation kettle 1. Two connecting members 73 are provided between the circular plate 71 and the scraper ring 72, and are located at the left and right portions of the scraper ring 72. The front and rear portions of the bottom of the circular plate 71 are fixedly connected with mounting plates 74 for cooperating with the installation of a pushing assembly 75. A pushing assembly 75 is provided between the two mounting plates 74 for pushing the scraper ring 72.

[0036] Furthermore, the pushing component 75 includes a motor 752 for providing power for the component. The motor 752 is fixedly connected to the mounting plate 74 located at the rear. The output end of the motor 752 is fixedly connected to a rotating shaft 751 for connecting to a push plate 753. The rotating shaft 751 passes through the two mounting plates 74 and is rotatably connected thereto. The front and rear portions of the outer wall of the rotating shaft 751 are fixedly connected to the push plate 753, which is elliptical.

[0037] like Figure 4 - Figure 5 As shown, the connecting member 73 includes a hollow rod 731 for connecting various components. The inner wall of the hollow rod 731 is slidably connected with a sliding rod 732 for cooperating with the hollow rod 731.
