Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] For example, see Figure 1-6 A material drying system for biomass power generation includes an operating table 1 and a collecting barrel 6. A fixed box 2 is fixedly installed on the top of the operating table 1. A feeding box 21 is fixedly installed on the top of the fixed box 2. A drying box 3 is also fixedly installed inside the fixed box 2. A material drop opening 31 is opened on the top of the drying box 3, and the material drop opening 31 is connected to the bottom of the feeding box 21. A material conveying plate 33 is slidably connected inside the material drop opening 31. A heating box 4 is also arranged on the top of the fixed box 2. A plurality of gas delivery pipes 41 are connected to the gas outlet end of the heating box 4. The plurality of gas delivery pipes 41 are away from one end of the heating box 4. The ends all penetrate the tops of the fixed box 2 and the drying box 3 and extend to the interior of the drying box 3, wherein a discharge port is also provided at one end of the fixed box 2 away from the feeding box 21, and the discharge port is communicated with the drying box 3, a discharge plate 22 is fixedly installed on the discharge port, a collecting barrel 6 is arranged on the side of the operating table 1 close to the discharge plate 22, and the collecting barrel 6 is communicated with the discharge plate 22, and a plurality of air delivery pipes 41 are fixedly installed at the bottom with a jet cylinder 42, a jet hole is provided on the jet cylinder 42, and the jet hole is communicated with the air delivery pipe 41, and the jet holes are all located toward the surface of the delivery plate 33;

[0028] When the device is used, the material to be dried is first added into the drying box 3 through the feeding box 21 and the material discharge port 31, and the heating box 4 is turned on, so that the hot air generated by the heating box 4 is transported to the air jet 42 through the air pipe 41, and then sprayed into the drying box 3 through the air jet holes on the air jet 42, so that the temperature in the drying box 3 is increased;

[0029] When in use, the material in the drying box 3 falls onto the conveying plate 33 through the drop opening 31. Meanwhile, the conveying plate 33 is inclined. The material falling onto the conveying plate 33 moves downward under the action of gravity. When passing through the bottom of the air jet 42, the material is dried by the hot air ejected from the air jet 42, making the drying more thorough. The dried material is discharged to the collecting barrel 6 through the discharge plate 22 for storage.

[0030] By setting up an inclined conveying plate 33, when in use, the material can be moved downward from the conveying plate 33 under the action of gravity, which is convenient for collection. At the same time, by setting up multiple air pipes 41 and air jets 42, during drying, continuous air jets through multiple air jets 42 can make the material drying more thorough, which is convenient for subsequent use.

[0031] For example 2, please refer to Figure 2 and Figure 3 A material distribution cylinder 32 is also provided inside the blanking port 31, and the two ends of the material distribution cylinder 32 are rotatably connected to the inner walls on both sides of the blanking port 31 respectively, and a driving motor is also fixedly installed in the inner wall of the blanking port 31, and the output end of the driving motor is fixed to one end of the material distribution cylinder 32 through a coupling, and a blanking plate 34 is also fixedly installed on the side of the drying box 3 near the blanking port 31, and the end of the blanking plate 34 near the fixed box 2 is fixed to the inner wall of the fixed box 2, and a feeding plate 33 is arranged directly below the blanking plate 34, and the feeding plate 33 slides on the inner wall of the drying box 3 on both sides near the drying box 3, and a plurality of vibration springs 35 are also fixedly installed on the inner wall of the bottom of the drying box 3, and the ends of the plurality of vibration springs 35 near the feeding plate 33 are fixedly installed on the bottom of the feeding plate 33, and a vibration component 5 is also provided at the bottom of the inner wall of the drying box 3;

[0032] When in use, the driving motor in the drop opening 31 is started, so that the driving motor drives the dividing barrel 32 to rotate. When the material enters the drop opening 31 from the feeding box 21, the material is separated into several parts under the action of the dividing barrel 32, and falls on the conveying plate 33 in batches, so as to avoid that all the materials fall and accumulate at one time to affect the drying effect. Through the provided dropping plate 34, when the material falls from the dividing barrel 32, the dropping plate 34 can make all the falling materials fall on the conveying plate 33;

[0033] When drying, the vibration assembly 5 in the drying box 3 is started, and the multiple vibration springs 35 at the bottom of the drying box 3 are cooperated to make the conveying plate 33 vibrate up and down, so that the materials on the conveying plate 33 are lifted up, and the agglomerated materials are scattered when falling, so that the drying is more thorough. At the same time, when the conveying plate 33 vibrates, the discharge of the dried materials is further promoted to avoid material accumulation.

[0034] For example 3, please refer to Figure 3 , Figure 4 and Figure 5 The vibration assembly 5 includes a first cam 51 and a second cam 52. Two rotation grooves 36 are provided on the bottom of the inner wall of the drying box 3. The first cam 51 and the second cam 52 are respectively rotatably connected to the adjacent rotation grooves 36. A transmission shaft 53 is fixedly installed on the surface on the same side of the first cam 51 and the second cam 52. A transmission belt 54 is provided between the two transmission shafts 53. The first cam 51 and the second cam 52 are transmission-connected through the transmission belt 54. The vibration assembly 5 also includes a servo motor 56. The servo motor 56 is fixedly installed at the bottom of the inner wall of the drying box 3. The output end of the servo motor 56 is fixed to the first cam 51 through a coupling. Auxiliary fixing plates 55 are also provided on both sides of the first cam 51 and the second cam 52. The auxiliary fixing plates 55 are fixedly installed on the bottom of the inner wall of the drying box 3. The first cam 51 and the second cam 52 are respectively rotatably connected to the adjacent auxiliary fixing plates 55 on both sides.

[0035] When in use, first start the servo motor 56, so that the servo motor 56 drives the first cam 51 to rotate, and the first cam 51 drives the second cam 52 to rotate through the transmission shaft 53 and the transmission belt 54. When the first cam 51 and the second cam 52 rotate, they continuously hit the bottom of the feed plate 33, and cooperate with the vibration spring 35 on the drying box 3 to make the feed plate 33 vibrate up and down;

[0036] By setting up the vibration component 5, when in use, the first cam 51 can simultaneously drive the second cam 52 to rotate through the transmission shaft 53 and the transmission belt 54, so that the vibration effect is more obvious. By setting up multiple auxiliary fixing plates 55, the first cam 51 and the second cam 52 can be more stably rotated.

[0037] Working principle: When in use, first start the driving motor in the drop port 31, so that the driving motor drives the material distribution barrel 32 to rotate. When the material enters the drop port 31 from the feeding box 21, the material is separated into several parts under the action of the material distribution barrel 32, and falls on the conveying plate 33 in batches. The heating box 4 is turned on, so that the hot air generated by the heating box 4 is transported to the air injection barrel 42 through the air delivery pipe 41, and then sprayed into the drying box 3 through the air injection holes opened on the air injection barrel 42, so that the temperature in the drying box 3 increases;

[0038] First, the servo motor 56 is started, so that the servo motor 56 drives the first cam 51 to rotate, and the first cam 51 drives the second cam 52 to rotate through the transmission shaft 53 and the transmission belt 54. When the first cam 51 and the second cam 52 rotate, they continuously hit the bottom of the conveying plate 33, and cooperate with the vibration spring 35 on the drying box 3 to make the conveying plate 33 vibrate up and down, so that the material on the conveying plate 33 is lifted, and the agglomerated material is dispersed when falling, so that the drying is more thorough. At the same time, when the conveying plate 33 vibrates, the discharge of the dried material is further promoted to avoid material accumulation. The dried material is discharged into the collecting barrel 6 through the discharge plate 22 for storage.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
