[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A clog-resistant pellet mill for biomass pellet processing includes a pellet mill body 1. The pellet mill body 1 includes a base 101, a drive component 102, a pellet mill chamber 103, a feed hopper 104, and a discharge shell 105. An auxiliary feeding component 2 is provided in the inner cavity of the feed hopper 104, and an auxiliary drying component 3 is provided on the top of the discharge shell 105.

[0027] The auxiliary feeding assembly 2 includes a support frame 201. The support frame 201 is fixedly connected to the pelleting chamber 103 on the side closest to the pelleting chamber 103. A drive motor 202 is fixedly connected to the top of the support frame 201. A transmission rod 203 is fixedly connected to the output shaft of the drive motor 202. The bottom of the transmission rod 203 passes through the support frame 201 and extends sequentially into the feed hopper 104 and the pelleting chamber 103. A spiral auger 204 is fixedly connected to the bottom of the surface of the transmission rod 203. Fixed rods 205 are fixedly connected to the top of both sides of the transmission rod 203. A stirring rod 206 is fixedly connected to the bottom of the fixed rod 205. A scraper 207 for use with the feed hopper 104 is fixedly connected to the side of the fixed rod 205 away from the transmission rod 203.

[0028] In this embodiment, by setting up a pellet mill body 1, a base 101, a drive component 102, a pelleting chamber 103, a feed hopper 104, a discharge shell 105, an auxiliary feeding component 2, and an auxiliary drying component 3, during use, the auxiliary feeding component 2 can assist in pushing biomass raw materials from the feed hopper 104 into the pelleting chamber 103, avoiding the accumulation of raw materials in the feed hopper 104, ensuring continuous and stable feeding, and stirring the biomass raw materials in the feed hopper 104 to prevent clumping, allowing the raw materials to enter the pelleting chamber 103 more evenly, and timely scraping off the damp raw materials adhering to the inner wall of the feed hopper 104, reducing feeding difficulties caused by raw material adhesion, and greatly improving feeding efficiency. The auxiliary drying component 3 can assist in drying the biomass pellets passing through the discharge shell 105 during the feeding process, thereby effectively removing excess moisture from the pellets, stabilizing their shape, preventing deformation and adhesion of the pellets due to moisture, and improving the quality and stability of the biomass pellets.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the auxiliary drying component 3 includes a fixing frame 301, which is located at the top of the feeding shell 105. A drying fan 302 is provided in the inner cavity of the fixing frame 301, and multiple heating tubes 303 are fixedly connected to the bottom of the inner wall of the fixing frame 301.

[0030] Specifically, such as Figure 1 , Figure 4 As shown, the top of the front and rear sides of the drying fan 302 are fixedly connected with fixing strips 304. The side of the fixing strip 304 near the inner wall of the fixing frame 301 is fixedly connected to the inner wall of the fixing frame 301. The top of the fixing frame 301 is fixedly connected with a filter screen plate 305.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a fixing block 306 is fixedly connected to the rear side of the fixing frame 301, and the side of the fixing block 306 near the pelleting chamber 103 is fixedly connected to the pelleting chamber 103.

[0032] In this embodiment: by setting up a fixed frame 301, a drying fan 302, a heating tube 303, a fixing strip 304, a filter screen 305, and a fixing block 306, when feeding the compressed biomass pellets, the drying fan 302 inside the fixed frame 301 can be activated, causing the drying fan 302 to output airflow, which is then heated by the heating tube 303. The hot airflow assists in drying the biomass pellets passing through the feeding shell 105, thereby effectively removing excess moisture from the pellets, stabilizing their shape, and preventing problems such as deformation and sticking due to moisture, thus improving the quality and stability of the biomass pellets. The fixing strip 304 can stably fix the drying fan 302 inside the fixed frame 301. The filter screen 305 can prevent debris from entering the fixed frame 301 and affecting the drying fan 302. The fixing block 306 can support and fix the fixed frame 301.

[0033] Specifically, such as Figure 3 As shown, the top of the support frame 201 is provided with a movable hole 4 that works with the transmission rod 203. The top of the surface of the transmission rod 203 is rotatably connected to the inner wall of the movable hole 4 through a bearing.

[0034] Specifically, such as Figure 1 , Figure 3 As shown, a rubber scraper 5 is fixedly connected to the side of the scraper plate 207 away from the fixed rod 205, and the side of the rubber scraper 5 near the inner wall of the feed hopper 104 is in close contact with the inner wall of the feed hopper 104.

[0035] In this embodiment: by setting the movable hole 4, the transmission rod 203 can pass through the support frame 201 and rotate easily through the bearing. By setting the rubber scraper 5, the adhesion between the scraper plate 207 and the inner wall of the feed hopper 104 can be increased, thereby improving the scraping effect on the biomass raw materials adhering to the inner wall of the feed hopper 104.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a control panel 6 is provided on the right side of the top of the base 101, which is used in conjunction with the auxiliary feeding assembly 2 and the auxiliary drying assembly 3. A support bar 7 is fixedly connected to the bottom of the control panel 6, and the bottom of the support bar 7 is fixedly connected to the right side of the top of the base 101.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, a movable push handle 8 is fixedly connected to the rear side of the base 101, and an anti-slip handle cover 9 is fitted on the surface of the movable push handle 8.

[0038] In this embodiment: by setting up the control panel 6, the operator can conveniently control the auxiliary feeding component 2 and the auxiliary drying component 3 to work. By setting up the support bar 7, the control panel 6 can be supported and fixed. By setting up the movable push handle 8, the pellet mill body 1 can be easily moved. By setting up the anti-slip handle 9, the friction and the grip comfort of the movable push handle 8 can be increased.

[0039] Working Principle: During operation, biomass raw materials are added to the feed hopper 104 of the pellet mill body 1. The drive motor 202 is then activated via the control panel 6, causing its output shaft to rotate the transmission rod 203. The transmission rod 203 then rotates the spiral auger 204, which assists in pushing the biomass raw materials from the feed hopper 104 into the pelleting chamber 103, preventing accumulation and blockage and ensuring continuous and stable feeding. Simultaneously, the fixing rod 205 rotates with the transmission rod 203, driving the stirring rod 206 to rotate. This stirring rod 206 agitates the raw materials in the feed hopper 104, preventing agglomeration and ensuring more even distribution into the pelleting chamber 103. Furthermore, the fixing rod 205 rotates the scraper plate 207, whose rubber scraper strips 5 interact with the feed... The inner wall of the feed hopper 104 is in close contact, so that the scraper plate 207 and the rubber scraper 5 can promptly scrape off the damp raw materials adhering to the inner wall of the feed hopper 104, reducing feeding obstruction caused by raw material adhesion and greatly improving feeding efficiency. After the biomass raw materials enter the pelleting chamber 103 of the pellet mill body 1, the pellet mill body 1 can perform pelleting work on the biomass raw materials. Then, the formed biomass pellets will enter the feeding shell 105 from the pelleting chamber 103 for feeding. At this time, the drying fan 302 in the fixed frame 301 can be started through the control panel 6, so that the drying fan 302 outputs airflow and heats the airflow through the heating pipe 303. The hot airflow assists in drying the biomass pellets passing through the feeding shell 105, thereby effectively removing excess moisture from the pellets, stabilizing and shaping them, preventing problems such as deformation and adhesion of the pellets due to moisture, and improving the quality and stability of the biomass pellets.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
