[0026] A feeding hopper 11 is installed on the front wall of the furnace body. Two sets of first circular through holes are formed on both sides of the feeding hopper 11. A first bearing seat 12 is inserted into each first circular through hole. A first bearing 13 is installed on the first bearing seat 12. A first connecting rod 14 is installed inside the first bearing 13. A first sleeve 15 is inserted into the first connecting rod 14. The first connecting rod 14 has a hollow structure. A first steering knuckle 16 is installed at one end of one of the first connecting rods 14 in each set, and a second steering knuckle 17 is installed on the other first connecting rod 14 in each set. A first arc-shaped cutting blade 18 is provided on the first sleeve 15. First drive mounting seats 19 are installed on both the feeding hopper 11 and the side walls of the furnace body. Each first drive mounting base 19 is equipped with a variable frequency motor 20. A first connecting rod 21 is installed on the drive end of the variable frequency motor 20. A first gear 22 is provided on the first connecting rod 21. A second gear 23 is mounted on the first connecting rod 14 located above the first gear 22.

A feeding machine 25 is provided on the side wall of the feeding bin 11. A toggle structure is provided on the lower furnace body 2.

[0027] It should be noted that the feeding hopper installed on the furnace body is used to feed the straw into the furnace. The straw bales enter the feeding hopper and fall onto the first sleeve 15. The first sleeve 15 is supported by the first connecting rod 14 on the first bearing 13. The drive end of the variable frequency motor 20 rotates, driving the first gear 22 to rotate. The first connecting rod 14 is fitted with a second gear 23. The first gear 22 and the second gear 23 are fitted with a first chain 24. Therefore, the rotation of the drive end of the variable frequency motor 20 drives the first gear 22 to rotate. Due to the traction of the first chain 24, the second gear 23 rotates, thereby rotating the first connecting rod 14, which in turn rotates the first sleeve 15. This causes the first arc-shaped cutting blade 18 to rotate, tearing the straw bales that fall above. Since the rotation direction of the first sleeve 15 is consistent, the straw bales can be torn and pushed towards the furnace body while being torn. The rotation of the drive end of the variable frequency motor 20 tears the straw bales, preventing them from clumping together and falling off, thus forming an interception and tearing effect, which facilitates the tearing and dispersion of the straw bales.

[0028] Water pipes 26 are installed on the first steering knuckle 16 and the second steering knuckle 17.

[0031] It should be noted that: the falling straw is transported into the furnace body for burning via the grate 35. The grate 35 is supported by the first roller shaft 32 and the second roller shaft 34. The drive end of the grate motor 60 is connected to the first roller shaft 32, so it drives the first roller shaft 32 to rotate, and the grate 35 to rotate, facilitating the transport and movement of the straw falling on the grate 35. The third insert 28 is installed on the sixth bearing on the fourth bearing seat 36, and the third insert rod 38 is installed inside the third insert 28. The fifth gear 41 and the sixth gear 42 of the third connecting rod 40 on the drive end of the third servo motor 30 are connected by the second chain 43. Therefore, when the drive end of the third servo motor 30 rotates, it drives the sixth gear 42 to rotate, thereby causing the third insert 28 to rotate. The three servo motors 30 rotate, thereby rotating the third insert. The paddle 29 on the third insert 28 rotates, moving the straw on the grate 35 to prevent the straw from piling up and to allow air between the straws for combustion. The third insert 28 has different heights, which facilitates the movement of the straw. The second micro pump 45 draws water out through the seventh connecting pipe 44, transports it to the second distributor 47 through the eighth connecting pipe 46, and then transports it to the fifth steering knuckle 39 through the ninth connecting pipe 48, flowing into the third insert 28 to facilitate cooling of the third insert 28. The tenth connecting pipe 49, which is connected to the cavity interlayer, is installed through another fifth steering knuckle 39, facilitating water transportation into the cavity interlayer and achieving water circulation.

The first support column 55 installed on the drive end of the hydraulic pump first hydraulic cylinder 50 also serves as a support for the blocking door 51. When the drive end of the hydraulic pump first hydraulic cylinder 50 extends, it pushes the blocking door 51 upward, exposing the inlet end of the feed hopper 11. The straw bales are placed on the support frame 53, with one end close to the push frame 52. The support frame 53 is lower near the feed hopper 11 and higher away from the feed hopper 11. The lower end is connected to the lower end of the feed inlet of the feed hopper 11 and has an inclined angle. The drive end of the hydraulic pump second hydraulic cylinder 61 retracts, driving the push frame. 52. Push the round bale of straw to move, pushing it onto the small platform inside the feeding hopper 11 for preheating and vaporization. The straw enters the hopper through the feed inlet. After the second hydraulic cylinder 61 of the hydraulic pump extends and resets, the first hydraulic cylinder 50 of the hydraulic pump resets, lowering the blocking door 51 to block the feed hopper inlet. The next round bale of straw is placed on the support frame 53 and pushed again. At this time, the previous round bale of straw placed on the small platform of the feeding hopper 11 is also pushed into the boiler. The device runs again.
