Specific embodiments

[0025] Now, the present utility model will be further described in detail with reference to the drawings.

[0026] Please refer to Figures 1-4 As shown, in this embodiment, a biomass fuel burner is provided, which includes a combustion chamber 1, a feed inlet 2 and a fixing frame 3. The feed inlet 2 is fixed at the top of the combustion chamber 1, and the fixing frame 3 is fixed on one side of the combustion chamber 1. The fixing frame 3 can fixedly install the adjustable auxiliary discharging assembly 4 and the rotating motor 5, and has good stability. The inner wall of the bottom of the fixing frame 3 is fixedly installed with the adjustable auxiliary discharging assembly 4. A furnace bridge 8 is fixedly installed inside the combustion chamber 1. A limiting plate 9 is fixed at the bottom of the furnace bridge 8. A part of the adjustable auxiliary discharging assembly 4 is located between the two limiting plates 9. The limiting plate 9 has a limiting effect on the adjustable auxiliary discharging assembly 4. The rotating motor 5 is fixedly installed on the top of the fixing frame 3. The output end of the rotating motor 5 is provided with a rotating shaft 10, and the other end of the rotating shaft 10 is rotatably installed on the other side inside the combustion chamber 1.

[0027] A stirring rod 11 is fixedly installed on the outer side of the rotating shaft 10. The stirring rod 11 is located inside the combustion chamber 1. Both the stirring rod 11 and the rotating shaft 10 are located above the furnace bridge 8, and can stir the biomass fuel above the furnace bridge 8. A through - opening is provided on the other side of the combustion chamber 1 to facilitate the cleaning of the biomass combustion waste. A rotating member 6 is rotatably installed on the combustion chamber 1, and a baffle 7 is fixed on the outer side of the rotating member 6. The baffle 7 is located inside the through - opening. An inclined plate 12 is fixedly installed on the inner wall of the bottom of the combustion chamber 1. The top of the inclined plate 12 is in contact with the adjustable auxiliary discharging assembly 4, which improves the cleaning effect of the waste on the inclined plate 12.

[0028] An application of one aspect of this embodiment is as follows: Biomass fuel can be poured into the combustion chamber 1 through the feeding port 2 for combustion. When the rotating motor 5 works, it can drive the rotating shaft 10 to rotate. The stirring rod 11 fixedly installed on the outer side of the rotating shaft 10 can rotate along with the rotation of the rotating shaft 10, so that the biomass fuel can be stirred, improving the combustion effect of the biomass fuel. The waste generated by the combustion of the biomass fuel can fall onto the top of the inclined plate 12 through the furnace bridge 8. Then, by using the adjustable auxiliary discharging assembly 4, the waste on the top of the inclined plate 12 can be cleaned. The waste is pushed to the through - opening, causing both the baffle 7 and the rotating member 6 to rotate, facilitating the cleaning of the waste generated by the biomass fuel.

[0029] The adjustable auxiliary discharging assembly 4 includes a servo - motor 401. The servo - motor 401 is fixedly installed on the inner wall of the bottom of the fixed frame 3. The output end of the servo - motor 401 is provided with a threaded rod 402. The other end of the threaded rod 402 is rotatably installed with a fixed block 404. The other side of the fixed block 404 is fixed on the other side inside the combustion chamber 1. The fixed block 404 can fix the other end of the threaded rod 402. A slider 403 is slidably installed on the threaded rod 402. The slider 403 is threadedly connected to the threaded rod 402. The bottom of the slider 403 is fixed with a mounting frame 405. The inner wall of the top of the mounting frame 405 is fixed with a spring 406. The other end of the spring 406 is fixedly installed with a scraper 407. A part of the scraper 407 is located inside the mounting frame 405. The contraction of the spring 406 enables the scraper 407 to move inside the mounting frame 405.

[0030] When this embodiment is in use, the bottom of the scraper 407 is in contact with the top of the inclined plate 12. The servo - motor 401 works to drive the threaded rod 402 to rotate. At the same time, both sides of the slider 403 are in contact with the two limiting plates 9. The limiting plates 9 have a limiting effect on the slider 403, enabling the slider 403 to slide on the threaded rod 402 instead of rotating. Finally, the positions of the mounting frame 405, the spring 406, and the scraper 407 can be adjusted. And the scraper 407 is fixedly installed on the inner wall of the top of the mounting frame 405 through the spring 406. The inclined plate 12 has a certain inclination, so that the bottom of the scraper 407 can always be in contact with the top of the inclined plate 12, and can clean the waste on the inclined plate 12.
