[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a high-efficiency crushing device for biomass fuel raw material production, including a first silo 1 and a third silo 8 placed horizontally, and a second silo 7 connected to one end of the first silo 1 and the third silo 8; a feed inlet 23 is opened on the side of the first silo 1 away from the second silo 7, and a feeding platform 6 is horizontally connected to the feed inlet 23, such as... Figure 1 As shown, the feeding platform 6 is used to place the raw materials for biomass fuel, which makes it easier for staff to push the raw materials to the feeding port 23, thereby ensuring a stable feeding of raw materials and bringing great convenience to the processing.

[0023] like Figure 2 , 3 As shown, a pressing mechanism is connected to the first hopper 1 via a telescopic mechanism 2. The pressing mechanism includes a mounting frame 16, which is fixedly connected to the telescopic mechanism 2. The telescopic mechanism 2 is one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. Meanwhile, multiple rotating rollers 4 are connected to the mounting frame 16 via a second rotating shaft 19. A second motor 17 is fastened to the top of the mounting frame 16. Multiple pulleys 18 are connected to one end of the second rotating shaft 19 and the output end of the second motor 17. Adjacent pulleys 18 are connected by belts. Multiple guide rods 3 penetrating the first hopper 1 are vertically connected to the top of the mounting frame 16. Under the guidance of the guide rods 3, the stability of the lifting and sliding of the mounting frame 16 can be improved.

[0024] When the raw materials are transported, multiple rotating rollers 4 can rotate synchronously under the drive of the second motor 17. Under the adjustment of the telescopic mechanism 2, the distance between the rotating rollers 4 and the bottom surface of the first hopper 1 can be controlled. Thus, the placement height of the rotating rollers 4 can be adjusted according to the required height of the raw materials to be crushed. At the same time, under the rotation of the second motor 17, the raw materials can be continuously transported towards the second hopper 7. In order to improve the friction between the rotating rollers 4 and the raw materials, multiple protrusions 5 are fastened circumferentially on the outer wall of the rotating rollers 4, so that the protrusions 5 can exert a gripping force on the raw materials, ensuring the normal transportation of the raw materials.

[0025] like Figure 3 , 4 As shown, a third motor 20 is fastened to the outer wall of the second hopper 7, and the output end of the third motor 20 is extended into the second hopper 7. A crushing blade 21 is fastened to the output end of the third motor 20. The crushing blade 21 cuts the raw material transported at the feeding platform 6 by rotating. The raw material transported to the connection between the first hopper 1 and the second hopper 7 by the rotating roller 4 can be initially crushed and cut by the action of the rotating crushing blade 21. The cut raw material falls into the third hopper 8 for secondary cutting and crushing processing.

[0026] Meanwhile, multiple first rotating shafts 14 are rotatably connected inside the third hopper 8. Each first rotating shaft 14 is connected to a spiral blade 15. Adjacent spiral blades 15 are staggered, and a first motor 9 is fastened to one end of the first rotating shaft 14. The raw material that has been initially crushed falls to the spiral blade 15 inside the third hopper 8. Under the action of the rotating spiral blade 15, the raw material can be crushed a second time, which greatly improves the efficiency of raw material crushing. Moreover, the simple structure effectively improves the practicality of the device.

[0027] In summary, this high-efficiency pulverizing device for biomass fuel production, when used, such as... Figure 4 As shown, a discharge pipe 11 is provided on the side of the third hopper 8 away from the second hopper 7. An inclined plate 13 is connected inside the third hopper 8 and tilts towards the discharge pipe 11. The raw material after secondary crushing falls to the top of the inclined plate 13. The inclined plate 13 is designed to improve the rapid discharge of the crushed raw material. A vibration motor 22 is fastened to the bottom of the inclined plate 13, which further improves the efficiency of the raw material falling. In order to improve the overall stability of the device, multiple support rods 10 are fastened between the third hopper 8 and the first hopper 1, and support legs 12 are fastened at the four corners of the bottom of the third hopper 8.
