[0042] Reference Figure 3 and Figure 4 The driving member 21 includes a first driving motor, which is mounted on the frame 1, and a rotating rod 22 is rotatably mounted on the frame 1. The output shaft of the first driving motor is coaxial with the rotating rod 22 and is fixedly mounted. A crushing knife 23 is mounted on the rotating rod 22 and a plurality of crushing knives are distributed circumferentially along the rotating rod 22. Each crushing knife 23 extends along the length direction of the rotating rod 22. The two rotating rods 22 are distributed up and down. When the rotating rod 22 located at the top drives the crushing knife 23 to rotate, a straw crushing opening is formed between the blade edge of the crushing knife 23 and the blade edge of the blade 121. After the straw enters from the feed port 11, it slides downward along the baffle 12, so that the straw contacts the crushing knife 23. The blade edge of the crushing knife 23 rotates, driving the straw to contact the blade edge of the blade 121, so that the straw is crushed between the crushing knife 23 and the blade 121. The lower rotating rod 22 and the crushing knife 23 located at the bottom assist in secondary crushing of the straw, thereby improving the crushing effect of the straw.

[0043] Reference Figure 2 and Figure 5 A granulating mechanism 3 is installed on the frame 1, and the granulating mechanism 3 includes a granulating plate 31 and an extrusion assembly 32. The granulating plate 31 is installed on the frame 1, and a plurality of granulating grooves 311 are evenly opened on the granulating plate 31. The granulating grooves 311 are recessed downward on the granulating plate 31, and a plurality of evenly distributed granulating holes 312 are opened on the groove wall on one side of the granulating groove 311, and the crushed straw falls into the granulating groove 311.

[0044] Reference Figure 5 and Figure 6 The extrusion assembly 32 includes an extrusion piece 321, a linkage rod 322 and an extrusion plate 323. The extrusion piece 321 includes a pushing cylinder, which is installed on the frame 1. The linkage rod 322 is slidably installed between the frame 1 and the granulation plate 31 along the length direction of the middle rotating rod 22. The extrusion plate 323 is installed on the linkage rod 322 and is located in the granulation groove 311. The pushing cylinder drives the extrusion plate 323 through the linkage rod 322 to extrude the crushed straw from the granulation hole 312, so that the crushed straw is formed into granules.

[0045] Reference Figure 2 and Figure 7A conveying mechanism 4 is installed on the frame 1, and the conveying mechanism 4 includes a collecting box 41, a conveying assembly 42 and a storage box 43. The collecting box 41 is installed on the frame 1, and a guide plate 411 is installed on the frame 1. The guide plate 411 extends along the length direction of the rotating rod 22, and one side of the guide plate 411 extends downwardly at an angle to the upper port of the collecting box 41. After being squeezed out of the granulation hole 312, the granular straw falls into the collecting box 41 along the guide plate 411.

[0046] The conveying assembly 42 includes a second drive motor 421 and a spiral conveying rod 422. The second drive motor 421 is installed on the frame 1.

The output shaft of the second drive motor 421 is coaxial with the spiral conveying rod 422 and is fixedly connected. A discharge port is provided on the side of the collecting box 41 away from the second drive motor 421. The storage box 43 is installed on the frame 1 and is located at the discharge port end of the collecting box 41. The second drive motor 421 drives the spiral conveying rod 422 to rotate. The straw entering the collecting box 41 enters the storage box 43 from the discharge port driven by the spiral conveying rod 422, thereby collecting the straw that is crushed and formed into particles.

[0047] The implementation principle of a biomass straw pelletizing device in the embodiment of the present application is:

[0048] The straw is fed in from the feed port 11 above the frame 1, so that the straw slides down along the baffle 12 to between the blade 121 and the crushing knife 23, the first drive motor is started, driving the rotating rod 22 to rotate, so that the crushing knife 23 crushes the straw, and when the straw is crushed, the blade 121 assists in crushing to improve the crushing effect of the straw.

[0049] When the straw is crushed, both groups of crushing knives 23 crush the straw, thereby improving the crushing effect of the straw.

[0050] The crushed straw falls down onto the granulation plate 31 and accumulates in the granulation groove 311. The cylinder drives the extrusion plate 323 to push the crushed straw through the linkage rod 322, so that the straw in the granulation groove 311 is squeezed out from the granulation hole 312, thereby forming granular straw.

[0051] The formed straw falls downward onto the guide plate 411 or into the collecting box 41. The straw that falls on the guide plate 411 slides downward into the collecting box 41, and the second drive motor 421 is started. The second drive motor 421 drives the spiral conveying rod 422 to rotate, so that the granular straw in the collecting box 41 moves along the spiral conveying rod 422 to the discharge port, and is then collected in the storage box 43.
