[0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice husks, etc.), which is different from fossil fuels. In national policies and environmental protection standards, direct burning of biomass is a highly polluting fuel and is only used in large stoves in rural areas and is not allowed in cities. The application of biomass fuel is actually mainly biomass molded fuel, which uses agricultural and forestry waste as raw materials and is made into various shapes (such as blocks, granules, etc.) through processes such as crushing, mixing, extrusion, and drying. It is a new type of clean fuel that can be directly burned.

[0003] However, since the main raw material for biomass fuel production, the debris particles, are relatively small, and the feeding device of some extruders has a simple structure, when conveying the particles or feeding them into the extruder, a large amount of debris raw material particles adhere to the inner wall of the feeding device and are difficult to fall off, which makes it easy for blockages to occur during the production process, resulting in the need to stop the production line and clean up the blocked raw materials, reducing production efficiency.

[0030] By setting up the anti-blocking mechanism 2, the two stirring scrapers 25 are driven by the dual-axis motor 22 to rotate, which can not only scrape off the debris raw materials attached to the inner wall of the funnel 1 that are difficult to fall, but also continuously stir the raw materials accumulated in the funnel 1 to avoid clogging the discharge port 26. The raw materials are transported into the extruder at a uniform speed in conjunction with the rotating first spiral blade 28, which to a certain extent avoids the situation where the production line stops due to raw material blockage, thereby ensuring production efficiency.

[0031] Among them Figure 3 、 Figure 4 and Figure 5As shown, the vibration mechanism 3 includes a limit assembly and a vibration assembly. The limit assembly includes a sealing cover 31 arranged on the top surface of the funnel 1. The bottom surface of the sealing cover 31 and the top surface of the funnel 1 are both provided with limit grooves 32. The inner walls of the two limit grooves 32 are rotatably connected to the limit rings 33. The sides of the two limit rings 33 close to each other are fixedly connected to the outer wall of the connecting rod 24. The vibration assembly includes a plurality of grooves 34 provided on the outer wall of the funnel 1. The front end and the end of the connecting rod 24 are rotatably connected to the connecting column 35. The bottom ends of the two connecting columns 35 are fixedly connected to the vibration block 36. The front end and the end of the connecting rod 24 are both provided with a torsion spring groove 37. The inner walls of the two torsion spring grooves 37 are fixedly connected to the torsion springs 38. The bottom ends of the two torsion springs 38 are fixedly connected to the vibration block 36.

The vibrating funnel will shake off and scatter the raw materials inside it, and the stirring of the stirring scraper 25 further improves the anti-blocking effect of the device.

[0033] Among them Figure 2 and Figure 3 As shown, the feeding mechanism 4 includes a driving component, a feeding component and a storage component. The driving component includes a connecting tube 41 fixedly connected to the outer wall of the funnel 1, the left end of the connecting tube 41 is fixedly connected to the feeding cylinder 42, the top of the feeding cylinder 42 is fixedly connected to the single-axis motor 43, the feeding component includes a third rotating shaft 44 fixedly connected to the output end of the single-axis motor 43, the bottom end of the third rotating shaft 44 extends to the inner wall of the feeding cylinder 42 and is fixedly connected to the second spiral blade 45, the storage component includes a storage box 46 fixedly connected to the bottom end of the feeding cylinder 42, the bottom end of the third rotating shaft 44 is rotatably connected to the inner bottom wall of the storage box 46, and a plurality of feed ports 47 are provided at the bottom end of the feeding cylinder 42.

[0034] By setting up the feeding mechanism 4, the single-axis motor 43 drives the second spiral blade 45 to rotate spirally in the feeding barrel 42. The debris raw materials accumulated in the storage box 46 enter the connecting pipe 41 through the feed port 47 under the spiral drive of the second spiral blade 45, completing the feeding operation.

[0035] A specific application of this embodiment is: by setting an anti-blocking mechanism 2, cooperating with the feeding mechanism 4 to transport the raw materials into the sealing cover 31, the raw materials fall into the funnel 1, wherein the extruder is fixed under the flange ring 29, driving the dual-axis motor 22 to drive the first rotating shaft 23 to rotate, the first rotating shaft 23 drives the connecting rod 24 to rotate around the first rotating shaft 23, and the connecting rod 24 drives the two stirring scrapers 25 to slide on the inner wall of the funnel 1 to scrape off the debris raw materials attached to the inner wall of the funnel 1. If there is too much raw material accumulated in the funnel 1, the two rotating stirring scrapers 25 can also play a stirring role, break up the accumulated raw materials, and promote the raw materials to enter the connecting sleeve through the discharge port 26. 21, at this time, the dual-axis motor 22 drives the second rotating shaft 27 to rotate, and the second rotating shaft 27 drives the first spiral blade 28 to rotate spirally, driving the raw materials entering the connecting sleeve 21 to be transported into the extruder device fixed under the flange ring 29, realizing the use of the dual-axis motor 22 to drive the two stirring scrapers 25 to rotate, which can not only scrape off the debris raw materials attached to the inner wall of the funnel 1 that are difficult to fall, but also continuously stir the raw materials accumulated in the funnel 1 to avoid clogging the discharge port 26, and cooperate with the rotating first spiral blade 28 to uniformly transport the raw materials into the extruder, to a certain extent avoiding the situation where the production line stops due to raw material blockage, thereby ensuring production efficiency.

The rotating connecting rod 24 drives the two limiting rings 33 to rotate around the first rotating shaft 23 in the two limiting grooves 32, and the rotating connecting rod 24 drives the connecting columns 35 and the vibration blocks 36 on both ends to rotate. Since the outer wall of the funnel 1 is provided with a plurality of grooves 34, the rotating vibration block 36 will continuously hit the protruding corners on both sides of the grooves 34 on the outer wall of the funnel 1. At this time, the vibration block 36 hits the convex corner, and under the interaction of forces, the vibration block 36 is driven to flip around the connecting column 35, driving the torsional The torsion spring 38 in the spring groove 37 is deformed. At this time, the torsion spring 38 is in a twisted state. After hitting one corner, the elastic action of the torsion spring 38 drives the vibration block 36 to reset, so that the vibration block 36 stays in the groove 34. Similarly, the rotating connecting rod 24 continuously drives the vibration block 36 to hit the convex corner and then reset in the groove 34, continuously vibrating the funnel 1, realizing the use of the rotating connecting rod 24 in the anti-blocking mechanism 2 to drive the vibration block 36 to cooperate with the elastic reset of the torsion spring 38, and continuously hit the convex corner of the outer wall of the funnel 1 to vibrate it. The vibrating funnel will shake off and scatter the raw materials inside it, and the stirring of the stirring scraper 25 further improves the anti-blocking effect of the device.

[0037] By setting up a feeding mechanism 4, driving the single-axis motor 43 to drive the third rotating shaft 44 to rotate, the third rotating shaft 44 drives the second spiral blade 45 to rotate spirally in the feeding barrel 42, and the debris raw materials accumulated in the storage box 46 enter the feeding barrel 42 through the feed port 47 under the spiral drive of the second spiral blade 45, completing the upward transportation of the raw materials. After the raw materials reach a certain height, they enter the connecting pipe 41, slide and fall into the sealing cover 31, completing the feeding function.
