[0028] Embodiment: As Figures 1-9 shown, the present invention provides a raw material crusher for biomass fuel processing, including a chassis 1, two crushing rollers 2, two rotating shafts 21 and a motor 22. The two crushing rollers 2 are arranged on the top wall of the chassis 1. The rotating shaft 21 penetrates through the crushing roller 2 and is fixedly connected to the crushing roller 2. One end of the chassis 1 is provided with an adjusting mechanism 3. By setting the adjusting mechanism 3, the adjusting mechanism 3 can adjust the distance between the two crushing rollers 2, so that the biomass fuel can be crushed into particles of different sizes according to the needs of the crushing operation. A dust removal mechanism 5 is arranged inside the chassis 1. By setting the dust removal mechanism 5, the dust removal mechanism 5 can remove dust from the crushed biomass fuel;

[0029] The adjusting mechanism 3 includes a first frame plate 31, which is fixedly installed on one side of the chassis 1. A chute 32 is formed on the first frame plate 31. Sliders 33 are slidably installed at both ends of the chute 32. First connecting rods 34 are fixedly installed on the upper surfaces of the two sliders 33. Sleeves 35 are fixedly installed at one ends of the two first connecting rods 34. A first rotating rod 37 is provided on one side of the chassis 1. One end of the first rotating rod 37 is fixedly connected to the driving output end of the motor 22. Two hollow rods 36 are slidably arranged on the first rotating rod 37. One end of one sleeve 35 is rotatably connected to one end of one hollow rod 36. Two clamping grooves 39 are formed on the first rotating rod 37. Two clamping blocks 38 are fixedly installed on the inner walls of the two hollow rods 36. Two of the clamping blocks 38 are slidably connected to the inner wall of one clamping groove 39. Conical gears 4 are fixedly installed at the middle parts of the two hollow rods 36 and one ends of the two rotating shafts 21. Adjacent two conical gears 4 are meshed with each other. A second frame plate 41 is fixedly installed on the top wall of the chassis 1. A guiding groove 42 is formed on the second frame plate 41. Two guiding blocks 43 are slidably installed on the inner wall of the guiding groove 42. One end of one rotating shaft 21 is rotatably connected to one guiding block 43. Second connecting rods 44 are fixedly installed on the outer walls of the two sleeves 35. One end of one second connecting rod 44 is fixedly connected to one side of one guiding block 43. A double-headed screw rod 45 is rotatably installed at one end of the first frame plate 31. The double-headed screw rod 45 penetrates through the chute 32 and is in threaded rotation connection with the two sliders 33. By rotating the double-headed screw rod 45, the double-headed screw rod 45 can drive the two sliders 33 to slide towards each other or away from each other in the chute 32. By driving the two sliders 33 to slide towards each other or away from each other in the chute 32, the sliders 33 can make the rotating shaft 21 and the crushing roller 2 move synchronously through the first connecting rod 34, the sleeve 35, the hollow rod 36, the conical gear 4, the second connecting rod 44 and the guiding block 43, so as to realize the adjustment of the distance between the two crushing rollers 2. When the motor 22 is started, the driving shaft of the motor 22 makes the first rotating rod 37 rotate. The first rotating rod 37 can make the hollow rod 36 rotate through the clamping block 38. The hollow rod 36 can make the rotating shaft 21 rotate through the conical gear 4. The rotating shaft 21 can make the crushing rollers 2 rotate synchronously. Due to the reverse transmission effect of the conical gear 4, the two crushing rollers 2 rotate synchronously in the opposite direction. The two crushing rollers 2 crush the biomass fuel under the action of synchronous reverse rotation. By arranging the guiding groove 42 and the guiding block 43, the guiding block 43 can slide horizontally along the inner wall of the guiding groove 42, so as to support the rotating shaft 21 and the crushing roller 2 and improve the stability of the rotating shaft 21 and the crushing roller 2.

[0030] One end of the chassis 1 is fixedly installed with a feeding hopper 11, and the other end of the chassis 1 is hingedly installed with a discharge cover plate 12. A number of uniformly distributed mounting brackets 13 are fixedly installed at the other end of the chassis 1. By setting the discharge cover plate 12, after the discharge cover plate 12 is turned downward and opened, the crushed biomass fuel at the bottom of the chassis 1 can be discharged. By setting the feeding hopper 11, the biomass fuel to be crushed can be added above the two crushing rollers 2.

[0031] One end of the double-headed screw rod 45 is fixedly installed with a runner 46. By setting the runner 46, it is convenient for the operator to rotate the double-headed screw rod 45.

[0032] The dust removal mechanism 5 includes two sleeve plates 51, two turning plates 52 and an equipment cover 57. One end of one turning plate 52 is arranged in one sleeve plate 51. Rubber strips 53 are fixedly installed at the other ends of the two turning plates 52. One side of the rubber strip 53 is in movable contact with the inner wall of the chassis 1. The equipment cover 57 is fixedly installed on the inner wall of the chassis 1. A suction fan 58 is fixedly installed on the inner wall of the equipment cover 57. An expansion hood 59 is fixedly installed at one end of the equipment cover 57. A dust discharge pipe 6 is fixedly installed at the other end of the equipment cover 57. By setting the sleeve plate 51, the turning plate 52 and the rubber strip 53, when the sleeve plate 51, the turning plate 52 and the rubber strip 53 turn, the sleeve plate 51, the turning plate 52 and the rubber strip 53 can turn the biomass fuel at the bottom of the chassis 1. At the same time, the rubber strip 53 is always in contact with the inner wall of the chassis 1, so that the crushed biomass fuel keeps moving, thus making the dust in the biomass fuel in a floating state. By setting the equipment cover 57, the suction fan 58, the expansion hood 59 and the dust discharge pipe 6, when the suction fan 58 operates, the suction fan 58 sucks the dust in the biomass fuel through the expansion hood 59, and the dust is discharged out of the chassis 1 through the expansion hood 59, the equipment cover 57 and the dust discharge pipe 6.

[0033] Two spring rods 54 are fixedly installed on the inner walls of the two sleeve plates 51. The telescopic ends of two adjacent spring rods 54 are fixedly connected to one end of a turning plate 52. Two sliding grooves 55 are opened on the inner walls of the two sleeve plates 51. One end of each of the four sliding grooves 55 is slidably installed with a sliding block 56. Two adjacent sliding blocks 56 are fixedly connected to one end of a turning plate 52. By setting the spring rod 54, the extended state of the spring rod 54 can push the turning plate 52 and the rubber strip 53, so that the rubber strip 53 can always be in contact with the inner wall of the chassis 1, and fully turn the biomass fuel at the bottom of the chassis 1. By setting the sliding groove 55 and the sliding block 56, the sliding block 56 slides along the inner wall of the sliding groove 55, thereby improving the stability of the turning plate 52.

[0034] On one side of the chassis 1, a motor 61 is fixedly installed. The driving output end of the motor 61 is fixedly installed with a second rotating rod 62. The second rotating rod 62 is rotationally connected to the chassis 1. The outer wall of the second rotating rod 62 is fixedly installed with a fixed roller 63. One end of the two sleeve plates 51 is fixedly connected to the outer wall of the fixed roller 63. By turning on the motor 61, the drive shaft of the motor 61 can drive the fixed roller 63 to rotate through the second rotating rod 62, and the fixed roller 63 can make the two sleeve plates 51, the two turning plates 52 and the two rubber strips 53 turn around the axis of the fixed roller 63.

[0035] Working principle: When biomass fuel needs to be crushed, first adjust the distance between the two crushing rollers 2 according to the crushing operation requirements;

[0036] The operator first manually rotates the runner 46. The runner 46 makes the double-headed screw 45 rotate. The double-headed screw 45 drives the two sliders 33 to slide towards each other or away from each other in the chute 32. The two sliders 33 make the two rotating shafts 21 and the two crushing rollers 2 move synchronously through the corresponding first connecting rod 34, sleeve 35, hollow rod 36, bevel gear 4, second connecting rod 44 and guide block 43, so that the distance between the two crushing rollers 2 meets the crushing operation requirements of the biomass fuel, thus conveniently realizing the adjustment of the distance between the two crushing rollers 2, and further facilitating the crushing process of biomass fuels with different particle sizes;

[0037] By turning on the motor 22, the drive shaft of the motor 22 makes the first rotating rod 37 rotate. The first rotating rod 37 makes the two hollow rods 36 rotate through the four clamping blocks 38. The two hollow rods 36 make the two rotating shafts 21 rotate through the four bevel gears 4. The two rotating shafts 21 make the crushing rollers 2 rotate synchronously, and the two crushing rollers 2 rotate in opposite directions synchronously. The two crushing rollers 2 crush the biomass fuel during the synchronous reverse rotation process and make the crushed biomass fuel fall to the bottom of the chassis 1;

[0038] At this time, the operator turns on the motor 61 and the suction fan 58. The drive shaft of the motor 61 can make the two sleeve plates 51, the two turning plates 52 and the two rubber strips 53 turn around the axis of the fixed roller 63 through the second rotating rod 62 and the fixed roller 63. During the turning process of the two sleeve plates 51, the two turning plates 52 and the two rubber strips 53, the crushed biomass fuel is continuously moved, making the dust in the biomass fuel in a floating state. The suction fan 58 sucks the dust in the biomass fuel through the diffuser 59, and the dust is discharged outside the chassis 1 through the diffuser 59, the equipment cover 57 and the dust exhaust pipe 6, thus conveniently realizing the dust removal of the crushed biomass fuel, and further effectively improving the quality of the subsequent prepared formed clean fuel.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
