A collection box 13 is slidably connected to the inner wall of the right side of the combustion furnace 1. A screening component 2 is arranged above the combustion furnace 1. A crushing component 3 is arranged above the combustion furnace 1.
[0026] Specifically, in order to prevent large amounts of biofuel from entering the combustion furnace, see [reference needed]. Figure 3 and Figure 4 In this embodiment, the screening component 2 includes four fixed columns 21, the bottom of which is fixedly connected to the top of the combustion furnace 1, and a screening plate 22 is provided above the combustion furnace 1.

During the rotation of the striking rod 23, it will contact the top of the connecting frame 231 and push it downward. When the connecting frame 231 moves downward, it will drive several connecting blocks 221 to slide downward on the outer surface of the corresponding fixed column 21.

[0031] In the implementation process, the deformed spring 222 will generate elastic force, and when the top of the connecting frame 231 is separated from the surface of the striking rod 23, the spring 222 will push the screening plate 22 to move downward to return to the original position due to the elastic force. Through the continuous rotation of the striking rod 23, the screening plate 22 will quickly move up and down, which can screen the raw materials on the top of the screening plate 22. The smaller biological raw materials will fall on the top of the guide frame 12 and enter the inside of the combustion furnace 1, and the larger biological fuels that are not completely crushed will be discharged into the collecting box 13 along with the up and down movement of the screening plate 22, which facilitates the staff to re-crush them for use.
