[0029] The crushing blades 34 on the crushing roller 1 32 and the crushing roller 2 33 are arranged in a staggered manner. The right end of the crushing roller 1 32 is fixedly connected to the left end of the driven gear 36 , and the right end of the crushing roller 2 33 is fixedly connected to the left end of the transmission gear 37 .

[0030] The transmission gear 37 is meshed with the driven gear 36 , and the bottom end of the motor 1 38 is fixedly connected to the inner right side of the fixed frame 35 .

[0035] The following is a detailed description of the working principle of the biomass fuel pellet machine.

[0036] like Figure 1-5As shown, when the biomass fuel pellet machine is in use, the raw material can first be put into the crushing box 31 through the feed hopper 4, and then the motor 1 38 can be started, and the motor 1 38 drives the transmission gear 37 to rotate, so that the transmission gear 37 drives the meshing driven gear 36 to rotate, and then the transmission gear 37 and the driven gear 36 can drive the crushing roller 1 32 and the crushing roller 2 33 to rotate, and then the raw material can be cut and crushed by a plurality of rotating crushing blades 34.

Qualified raw materials will pass through the screen plate 53 and fall into the collecting frame 7, while unqualified raw materials will slide through the inclined screen plate 53 to the left empty slot 51, and slide through the left empty slot 51 to the side frame 9, thereby completing the screening of the raw materials, thereby improving the quality of the biomass fuel and improving the use effect. Finally, the collecting frame 7 can be pulled out of the receiving chamber 6 through the handle 8, so that the qualified raw materials can be processed and used.
