A reset component is provided in the through hole, which is used to apply a force towards the axis of the granulation roller to the push rod.

2. The self-drying biomass pelletizing device according to claim 1, characterized in that: The outer wall of the push rod is in contact with the inner wall of the granulation hole.

3. The self-drying biomass pelletizing device according to claim 1, characterized in that: The reset assembly includes a reset spring and a reset ring plate. Both the reset spring and the reset ring plate are sleeved on the push rod. The reset ring plate is fixedly connected to the push rod. A reset ring groove is formed in the inner wall of the through hole. The reset ring plate is slidably disposed in the reset ring groove. One end of the reset spring abuts against the reset ring plate, and the other end of the reset spring abuts against the inner wall of the reset ring groove.

4. The self-drying biomass pelletizing device according to claim 1, characterized in that: The abutting assembly includes an abutting convex roller and an abutting shaft. The abutting convex roller is located inside the cavity. One end of the abutting shaft is fixedly connected to the abutting convex roller, and the other end of the abutting shaft passes through the end wall of the granulating roller. The abutting shaft is rotatably connected to the granulating roller and fixedly connected to the housing. The abutting shaft and the granulating roller are coaxially arranged. One end of the push rod located inside the cavity abuts against the outer wall of the abutting convex roller.
