Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1: As Figure 1 , Figure 2 As shown, a mobile biomass pellet mill for agricultural and forestry waste treatment includes a support platform 3. A push rod 4 is fixedly connected to one side of the top of the support platform 3. Four casters 5 are rotatably connected to the bottom of the support platform 3. The casters 5 have a self-locking function. A pelletizing device 2 is provided on the other side of the top of the support platform 3. A crushing device 1 is provided above the support platform 3.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, a support rod 6 is fixedly connected to one side of the top of the support platform 3, and a conveying pipe 7 is fixedly connected to the top of the support rod 6. A third servo motor 8 is fixedly connected to one end of the conveying pipe 7, and a spiral conveying shaft 9 that is rotatably connected to the inner wall of the conveying pipe 7 is fixedly connected to the output end of the third servo motor 8. After crushing, the powdered raw material will fall into the conveying pipe 7. At this time, the third servo motor 8 drives the spiral conveying shaft 9 to rotate, which can convey the raw material to the granulation device 2, realize the pretreatment of the raw material, reduce the difficulty of manufacturing granules from agricultural and forestry waste, and effectively improve production efficiency.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, the crushing device 1 includes a crushing chamber 101 that is fixedly connected to the side wall of the conveying pipe 7. Two first rotating shafts 106 rotatably pass through the inner wall of the crushing chamber 101. The two first rotating shafts 106 are respectively fixedly fitted with mutually cooperating crushing rollers 103. The top of the crushing chamber 101 is fixedly connected to a feeding hopper 102. Due to the rotation of the transmission gear 104, the driven gear 108 can be driven to rotate, thereby enabling the two crushing rollers 103 to crush agricultural and forestry waste.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a motor base 107 is fixedly connected to the front end of the crushing chamber 101. A first servo motor 105 is fixedly connected to the inner wall of the motor base 107. The output end of the first servo motor 105 is fixedly connected to one end of one of the first rotating shafts 106. A transmission gear 104 is fixedly sleeved on one end of one of the first rotating shafts 106, and a driven gear 108 that meshes with the transmission gear 104 is fixedly sleeved on one end of the other first rotating shaft 106. Agricultural and forestry waste materials are put into the crushing chamber 101 through the hopper 102, and the first rotating shaft 106 is driven to rotate by the first servo motor 105.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, the granulation device 2 includes a working chamber 201 fixedly connected to the other end of the conveying pipe 7. Support plates are respectively provided on both sides of the bottom end of the working chamber 201 to support the working chamber 201 and improve its stability during operation. The side wall of the working chamber 201 is fixedly connected to the discharge port 202. The middle of the inner wall of the working chamber 201 is fixedly connected to the granulation screen 208. The granulation screen 208 is a porous plate structure, which facilitates the raw material to be squeezed through the small holes to achieve granulation. After the powdered raw material falls into the working chamber 201, the second servo motor 207 drives the second rotating shaft 204 to rotate, which in turn drives the connecting block 203 to rotate. This allows the connecting block 203 to drive the pressure roller 205 to rotate, so that the pressure roller 205 squeezes the raw material falling on the granulation screen 208.

[0021] like Figure 1 , Figure 2 and Figure 4As shown, a second servo motor 207 is fixedly connected to the middle of the bottom end of the working chamber 201. A second rotating shaft 204, rotatably connected to the inner wall of the working chamber 201, is fixedly connected to the output end of the second servo motor 207. The top end of the second rotating shaft 204 rotatably passes through the granulation screen 208 and is fixedly connected to a connecting block 203. A pressure roller 205 is rotatably sleeved on the side wall of the connecting block 203. The pressure roller 205 is a wheel-shaped mechanism and contacts the top end of the granulation screen 208. During the rotation of the pressure roller 205, the pressure roller can press the granulation screen 208... The raw material is pressed into the small holes in the granulation mesh 208 to achieve granulation. The second rotating shaft 204 is fixedly connected to the side wall of the discharge plate 206 which is slidably connected to the bottom of the inner wall of the working chamber 201. The raw material is pressed into granules through the small holes on the granulation mesh 208 and falls to the bottom of the inner wall of the working chamber 201. At the same time, the discharge plate 206 on the side wall of the second rotating shaft 204 can be used to discharge the raw material through the discharge port 202 as the discharge plate 206 rotates, thereby realizing the granulation of the raw material, effectively improving the granulation effect and preventing the raw material from clogging.

[0022] It should be noted that, in use, the mobile biomass pellet mill for agricultural and forestry waste treatment puts the agricultural and forestry waste raw materials into the crushing chamber 101 through the feeding hopper 102, and uses the first servo motor 105 to drive the first rotating shaft 106 to rotate. At the same time, due to the rotation of the transmission gear 104, the driven gear 108 can be driven to rotate, so that the two crushing rollers 103 crush the agricultural and forestry waste. After crushing, the powdered raw materials will fall into the conveying pipe 7. At this time, the third servo motor 8 drives the spiral conveying shaft 9 to rotate, which can transport the raw materials to the pelletizing device 2 to achieve the pretreatment of the raw materials. After the powdered raw material falls into the working chamber 201, the second servo motor 207 drives the second rotating shaft 204 to rotate, which in turn drives the connecting block 203 to rotate. This, in turn, drives the pressure roller 205 to rotate, causing the pressure roller 205 to squeeze the raw material falling onto the granulation screen 208. The raw material is pressed into granules through the small holes on the granulation screen 208 and falls to the bottom of the inner wall of the working chamber 201. At the same time, the discharge plate 206 on the side wall of the second rotating shaft 204 rotates, and the raw material can be discharged through the discharge port 202, thus realizing the granulation of the raw material.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
