[0040] It should be noted that the motor 24 serves as an integral driving device, providing power for the entire device. After the motor 24 is started, the driving pulley 23 begins to rotate, and then the rotating shaft 55 is driven to work inside the cutting box 43 through the action of the transmission belt 21 and the driven pulley 22 to complete the subsequent chopping process of the biomass fuel.

[0041] The cutting box 43 and the cutting cover plate 41 are connected in coordination: the cutting box 43 and the cutting cover plate 41 are fixed by a plurality of bolt buckles to facilitate the subsequent opening of the cutting cover plate 41 and the inspection of the internal components of the cutting box 43. In addition, the feed hopper 42 can also be replaced according to different cutting materials to increase the scope of use.

[0042] Completion of preliminary cutting: the biomass material to be processed is transported to one end of the cutting box 43 through the feed hopper 42, and the rotating shaft 55 drives the cutting knife 10 and the fixed plate 11 to rotate, and the cutting knife 10 and the supporting blade 47 cooperate with each other, so as to cut the material. Then, with the continuous rotation of the cutting knife 10 and the action of the spiral plate 46, the cut-in-block material is transported to one side of the sleeve 64. During the transportation process, the block material is further chopped by the continuous rotation of the two cutting knives 9 and the cooperation with the partition 8, thereby completing the preliminary cutting effect of the material.

[0043] Reference Figure 3 , Figure 4 , Figure 5 and Fig.11 , further; the dehumidification assembly 5 includes an air collecting frame 51 and a rotating shaft 55, the rotating shaft 55 is rotatably connected to the support frame 1 through a bearing, one end of the rotating shaft 55 is fixedly connected to the air collecting frame 51, and the other end of the rotating shaft 55 passes through the two end side walls of the cutting box 43, the outer wall of the rotating shaft 55 on one side of the cutting box 43 is fixedly connected to the driven pulley 22, and the inner wall of the air collecting frame 51 is fixedly connected with a filter plate 52; a ventilation slot 53 is opened on the side wall of one end of the rotating shaft 55, and a plurality of uniformly distributed The exhaust slots 54 of the cloth, the rotating shaft 55 is located on the outer wall inside the cutting box 43 and is fixedly connected with the fan blades 551; the discharge assembly 6 includes a baffle 61 and a sleeve 64, the baffle 61 is fixedly connected to one end of the sleeve 64, the baffle 61 and the sleeve 64 are fixedly sleeved on the outer wall of the rotating shaft 55, the sleeve 64 is located on the outside of the fan blades 551, the outer wall of the sleeve 64 is fixedly connected with a plurality of discharge plates 62 distributed in a circular array, and the outer wall of the sleeve 64 is provided with a plurality of blowing holes 63 distributed in a circular array.

[0044] Further application of the rotating shaft 55: a detachable sealing plate is provided on one side of the air collecting frame 51, which can be used to timely seal the air collecting frame 51 when not in use, so as to reduce the clogging of the filter plate 52 by external dust. In the specific use process, the rotation of the rotating shaft 55 drives the fan blades 551 to rotate, thereby sucking the external air into the ventilation slot 53, and the function of the filter plate 52 is to reduce the external dust from entering the interior of the sleeve 64, thereby reducing the clogging of the blowing hole 63 from the inside, and the air flows into the interior of the sleeve 64 through the exhaust slot 54, and then with the fan The blowing of the blades 551 quickly delivers air into the interior of the cutting box 43 through the blowing holes 63, thereby air-drying the material in the crushing process to reduce the water content of the material itself and ensure the combustion effect of the material after crushing. In addition, an electric heating tube can be set on one side of the fan blade 551. By drying and heating the air and coordinating with the blowing of wind, the drying effect can be further improved, thereby drying the biomass material with more moisture to ensure the overall combustion effect. Here, the moisture content of the biomass fuel is not enough to produce a large number of water droplets through squeezing.

[0045] The wind force and the discharge plate 62 cooperate with each other: through the blowing of wind force and the continuous conveying of the feeding plate 71, the crushed material can be gradually accumulated between two adjacent discharge plates 62 and blocked by the baffle 61. The advantage of this is that on the one hand, it ensures the utilization of space so that the crushed material can be accumulated, avoiding the crushing assembly 7 from repeatedly crushing the material to improve the crushing efficiency. On the other hand, with the continuous rotation of the rotating shaft 55, the separated materials can be discharged one by one through the discharge hopper 44 in an orderly manner, and because the air flow rate of the blowing hole 63 is relatively fast, the blockage of the crushed material can be effectively reduced or avoided to ensure the effect of air drying the material.

[0046] Reference Figure 8-Figure 10, further; the crushing assembly 7 includes a feeding plate 71 and a fixed rod 73, one end of the fixed rod 73 is fixedly connected to the outer wall of the sleeve 64, and the other end of the fixed rod 73 is fixedly connected to the feeding plate 71, and each fixed rod 73 is fixedly connected to two expansion plates 74; the crushing assembly 7 also includes a shredding mechanism 72, the shredding mechanism 72 includes a gear plate 721, a crushing plate 722, a crushing blade 723 and a rotating rod 724, the rotating rod 724 is rotatably connected to one of the expansion plates 74, one end of the rotating rod 724 is fixedly connected to the gear plate 721, the gear plate 721 is meshed with the gear ring 45, and the outer wall of the rotating rod 724 is connected to the crushing plate 722 The outer wall of the rotating rod 724 is rotationally connected to the crushing blade 723; the crushing assembly 7 also includes a tumbling mechanism 75, which includes a gear plate 2 751, a tumbling plate 752 and a rotating rod 2 755. The rotating rod 2 755 is rotatably connected to another expansion plate 74. One end of the rotating rod 2 755 is fixedly connected to the gear plate 2 751, and the gear plate 2 751 is meshingly connected to the gear plate 1 721. The outer wall of the rotating rod 2 755 is fixedly connected to one end of the tumbling plate 752. The other end of the tumbling plate 752 is fixedly connected with a plurality of evenly distributed protrusions 753. The side wall of the tumbling plate 752 is provided with a groove 754 matching the crushing plate 722.

[0047] Fixing of the feed plate 71: Through the connection between the fixing rod 73 and the sleeve 64, the stability of the feed plate 71 during operation can be ensured, and the function of the expansion plate 74 is to provide a more sufficient area for the installation of the rotating rod 1 724 and the rotating rod 2 755, while reducing the utilization of the fixing rod 73 and enhancing the stability of the fixing rod 73.

[0048] The block material is further crushed by the shredder mechanism 72: during the rotation of the shaft 55, the sleeve 64 will be driven to rotate synchronously, and in this process, the shredder mechanism 72 and the tumbling mechanism 75 will also revolve around the sleeve 64, so that the material can be stirred and the crushing effect is more uniform. In addition, due to the rotation, the gear plate 721 and the gear ring 45 will be periodically meshed, thereby driving the multiple crushing discs 722 on the outer wall of the rotating rod 724 to rotate. At this time, the material in the conveying process can be cut and crushed, and the crushing blade 723 is sleeved on the outer wall of the rotating rod 724, so it will cooperate with the crushing disc 722 through the action of centrifugal force to further crush the material, and the crushing blade 723 will complementarily interfere with the tumbling plate 752 during movement, thereby improving the crushing effect and processing efficiency.

[0049] The linkage between the tumbling mechanism 75 and the shredding mechanism 72: During the rotation of the shredding mechanism 72, due to the meshing connection between the gear plate 1 721 and the gear plate 2 751, the rotating rod 2 755 is driven to rotate. At this time, the tumbling plate 752 not only turns the crushed material, but also drives the protrusion 753 to scatter the material that may be accumulated into blocks, thereby facilitating the crushing of the shredding mechanism 72. The protrusion 753 can be set to a cone or a triangle, which can further puncture the material, reduce the slippage between the biomass material and the crushing effect.

[0050] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
