[0032] Specifically, the propulsion assembly 3 includes two third connecting rods 31, which are respectively fixedly connected to the two sides of the rotating shaft 13, and each third connecting rod 31 is rotatably connected to a connecting block 32 at one end away from the rotating shaft 13, and a plurality of tamping rods 33 are fixedly installed at one end of each connecting block 32, and a plurality of brush bodies 34 are fixedly installed at the other end of each connecting block 32.

At this time, the fourth connecting rod 41 on the rotating shaft 13 also rotates with the rotating shaft 13, and the U-shaped frame 42 thereon can push the biomass particle fuel that is pushed to the edge of the slide 111 by the rolling roller 72 and the tamping rod 33 slightly toward the slide The middle part of the slide 111 is brought together to prevent the biomass particle fuel at the edge of the slide 111 from not being separated.

At this time, the output end of the electric push rod 21 moves upward, and the second connecting rod 25 on the swing component 8 and the ball head rod 81 cooperate to keep the connecting block 32 with one end of the brush body 34 tilted downward. At this time, the crushing component 7 will move upward with the sleeve 23, and no longer perform the crushing operation. As the rotating shaft 13 continues to rotate, the biomass particle fuel that meets the requirements can be scraped to the opening connected to the receiving tube 15 at the bottom of the slide 111 through the brush body 34 and the U-shaped frame 42.

[0037] Specifically, a plurality of bevel teeth 51 are fixedly installed at the bottom of the annular plate 5, and the material-prying assembly 6 includes two semicircular plates 61 symmetrically fixedly connected to both sides of the rotating shaft 13, and each semicircular plate 61 is fixedly connected to a bar frame 62, and each bar frame 62 is rotatably installed with a round rod 63 at one end close to the rotating shaft 13, and each round rod 63 is coaxially fixedly installed with a first bevel gear 64 at one end close to the rotating shaft 13, and each round rod 63 is coaxially fixedly installed with a second bevel gear 65 at one end away from the rotating shaft 13, and each first bevel gear 64 are meshed with the bevel teeth 51 on the annular plate 5, and a connecting shaft 66 is rotatably installed at the middle position of each bar frame 62 and at one end away from the rotating shaft 13. The two connecting shafts 66 in each bar frame 62 are connected by a transmission belt 67.

[0038] Specifically, the top of the receiving tube 15 is rotatably connected with a switch door 151, and the top of the receiving tube 15 is fixedly installed with an electric switch 152 for controlling the opening and closing of the switch door 151. A hot air pipe 153 is fixedly connected to one side of the receiving tube 15, and one end of the hot air pipe 153 penetrates the cylinder 1 and is connected to an external hot air source. When the electric switch 152 is activated, the switch door 151 rotates downward, and the biomass pellet fuel that meets the requirements will move toward the annular heating pipe 16 through the receiving tube 15. At this time, the external hot air source will slowly blow hot air into the annular heating pipe 16 through the hot air pipe 153, dry and dehydrate the biomass pellet fuel, and gradually push the biomass pellet fuel toward the lower barrel 17, so that the dried and dehydrated biomass pellet fuel falls on the screen 12.

[0039] Specifically, the top of the cylinder 1 is fixedly connected to a feed pipe 18 , and the bottom of the cylinder 1 is fixedly connected to a discharge pipe 19 . The semicircular plate 61 at the lower part of the rotating shaft 13 drives the round rod 63 to make a circular motion with the axis of the rotating shaft 13 as the center through the bar frame 62, and the first bevel gear 64 on the round rod 63 meshes with the bevel gear 51 at the bottom of the annular plate 5, so that the round rod 63 can rotate while making a circular motion, and the second bevel gear 65 rotates together with the round rod 63. Since the third bevel gear 68 meshes with the second bevel gear 65, the connecting shaft 66 at the middle position of the bar frame 62 rotates due to the meshing relationship between the third bevel gear 68 and the second bevel gear 65, and drives the transmission belt 67 to rotate, so that the material-shifting soft claw 69 fixedly installed on the transmission belt 67 rotates together with the transmission belt 67, and continuously shifts the biomass particle fuel on the screen 12 to prevent the biomass particle fuel that meets the requirements from accumulating and being difficult to collect, and enables the biomass particle fuel that meets the requirements to pass through the screen 12 and fall into the bottom of the cylinder 1, and finally be discharged and collected through the discharge pipe 19 at the bottom of the cylinder 1.

[0040] Specifically, an annular scraper plate 112 is also provided on the primary screening disc 11, and the annular scraper plate 112 is coaxially fixedly connected to the rotating shaft 13, and the bottom of the annular scraper plate 112 is in contact with the top of the primary screening disc 11, and the function of the annular scraper plate 112 is to scrape the biomass pellet fuel to be processed that is blocked on the sieve hole to the slide 111 on the side of the cylinder 1, and then the biomass pellet fuel to be processed will slide from the middle of the primary screening disc 11 to the slide 111 on the side, and the bottom of the primary screening disc 11 is fixedly connected to a powder outlet pipe 113, one end of the powder outlet pipe 113 passes through the cylinder 1, and the function of the sieve hole is to remove the powder in the biomass pellet fuel, separate it into the primary screening disc 11, and discharge it to the outside of the cylinder 1 through the powder outlet pipe 113 for collection, and these powders can be subsequently processed into qualified biomass pellet fuel.

[0041] Working principle: The biomass pellet fuel to be processed is discharged from the feed pipe 18 to the primary screening plate 11 in the cylinder 1. Since a number of sieve holes are provided in the middle of the primary screening plate 11, the function of the sieve holes is to remove the powder in the biomass pellet fuel, separate it into the primary screening plate 11, and discharge it to the outside of the cylinder 1 through the powder outlet pipe 113 for collection. These powders can be processed into qualified biomass pellet fuel later. The function of the annular scraper plate 112 is to scrape the biomass pellet fuel to be processed that is blocked on the sieve holes to the slide 111 on the side of the cylinder 1, and then the biomass pellet fuel to be processed will slide from the middle of the primary screening plate 11 to the slide 111 on the side. At this time, the motor 14 at the bottom of the cylinder 1 is started, and the output end of the motor 14 drives the rotating shaft 13 to rotate. At this time The crushing assembly 2, the propulsion assembly 3, the scraping assembly 4 and the material-dispensing assembly 6 all work together with the rotating shaft 13. The sleeve 23 in the crushing assembly 2 is fixedly connected to the output end of the electric push rod 21 through the bearing sleeve 22 at the top, and is slidably connected to the rotating shaft 13 at the bottom through the sliding cooperation of a plurality of protrusions and a plurality of slide grooves, so that the sleeve 23 can rotate together with the rotating shaft 13. The function of the bearing sleeve 22 is that when the sleeve 23 rotates, it will not affect the electric push rod 21 to slide the sleeve 23 up and down. Then the first connecting rod 24 on the sleeve 23 drives the fixed frame 71 in the rolling component 7 to rotate, so that the rolling roller 72 in the fixed frame 71 can grind the biomass particle fuel in the slideway 111. The purpose of this operation is to bond the biomass particles together. The biomass pellet fuel is separated. Since the biomass pellet fuel has a certain hardness, no new powder will be formed during the crushing operation. At the same time, the third connecting rod 31 in the propulsion assembly 3 drives the connecting block 32 to rotate. At this time, the output end of the electric push rod 21 moves downward, and the second connecting rod 25 on the swing component 8 and the ball head rod 81 cooperate to keep the connecting block 32 with one end of the tamping rod 33 downward, so that the biomass pellet fuel separated by the crushing roller 72 can be dispersed and stirred again, so that the biomass pellet fuel can be spread as flat as possible in the slideway 111, and the tamping rod 33 itself also has the effect of separating the biomass pellet fuels that are bonded together. At this time, the fourth connecting rod 41 on the rotating shaft 13 also Rotating together with the rotating shaft 13, the U-shaped frame 42 thereon can push the biomass particle fuel pushed to the edge of the slide 111 by the crushing roller 72 and the tamping rod 33 slightly toward the middle of the slide 111, so as to prevent the biomass particle fuel at the edge of the slide 111 from not being separated. After the repeated crushing, stirring and approaching operations, the biomass particle fuel can be processed into qualified biomass particle fuel with uniform particle size. At this time, the output end of the electric push rod 21 moves upward, and the second connecting rod 25 on the swinging component 8 and the ball head rod 81 cooperate to keep the connecting block 32 in a state where one end of the brush body 34 is tilted downward. At this time, the crushing component 7 will move upward together with the sleeve 23, and no longer perform the crushing operation. As the rotating shaft 13 continues to rotate,The biomass pellet fuel that meets the requirements can be scraped to the opening at the bottom of the slide 111 and connected to the receiving tube 15 by the brush body 34 and the U-shaped frame 42. At this time, the electric switch 152 is started, so that the switch door 151 rotates downward, and the biomass pellet fuel that meets the requirements will pass through the receiving tube 15 and move toward the annular heating tube 16. At this time, the external hot air source will slowly blow hot air into the annular heating tube 16 through the hot air pipe 153 to dry and dehydrate the biomass pellet fuel, and gradually push the biomass pellet fuel to the lower barrel 17, so that the dried and dehydrated biomass pellet fuel falls on the screen 12. At this time, the semicircular plate 61 at the lower part of the rotating shaft 13 drives the round rod 63 to make a circular motion with the axis of the rotating shaft 13 as the center through the bar frame 62, and the first bevel gear on the round rod 63 64 meshes with the bevel gear 51 at the bottom of the annular plate 5, so that the round rod 63 can rotate while moving in a circular motion, and the second bevel gear 65 rotates with the round rod 63. Since the third bevel gear 68 meshes with the second bevel gear 65, the connecting shaft 66 at the middle position of the bar frame 62 rotates due to the meshing relationship between the third bevel gear 68 and the second bevel gear 65, and drives the transmission belt 67 to rotate, so that the material-pickup soft claw 69 fixedly installed on the transmission belt 67 rotates with the transmission belt 67, and continuously pokes the biomass particle fuel on the screen 12, preventing the biomass particle fuel that meets the requirements from accumulating and being difficult to collect, and allowing the biomass particle fuel that meets the requirements to pass through the screen 12 and fall into the bottom of the cylinder 1, and finally be discharged and collected through the discharge pipe 19 at the bottom of the cylinder 1.
