[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 6 The utility model provides a bio-based raw material crushing device, including a crushing box 1, the top of the crushing box 1 is fixedly connected to a feed hopper 12; the bottom of the crushing box 1 is fixedly connected to a discharge hopper 55; a crushing assembly is provided in the crushing box 1, and the crushing assembly includes two crushing blade wheels 2 and two crushing rollers 31; the crushing blade wheels 2 are rotatably connected to the bottom of the crushing box 1 through a blade shaft 21; the crushing rollers 31 are rotatably connected to the crushing box 1 through roller shafts, and the crushing blade wheels 2 are arranged above the crushing rollers 31; the One end of the cutter shaft 21 extends to the outside of the crushing box 1 and is fixedly connected to a gear 22, and the two gears 22 are meshed with each other; the other end of the cutter shaft 21 extends to the outside of the crushing box 1 and is fixedly connected to a first rotating wheel 23; one end of the roller shaft extends to the outside of the crushing box 1 and is fixedly connected to a second rotating wheel 32, and a belt 33 is provided between the first rotating wheel 23 and the second rotating wheel 32 on the same side; the outer wall of the crushing box 1 is fixedly connected to a first motor 3, and the output shaft of the first motor 3 is fixedly connected to one end of one of the roller shafts.

[0028] During operation, the bio-based raw materials are put into the feed hopper 12. In order to solve the problem that the overall crushing efficiency is low due to single-time crushing, the raw materials pass through the crushing wheel 2 and the crushing roller 31 in the crushing box 1. By turning on the first motor 3, the first motor 3 drives the roller shaft to rotate through the output shaft, and drives the crushing roller 31 and the second rotating wheel 32 to rotate through the roller shaft, and drives the belt 33 to rotate through the second rotating wheel 32, and drives the first rotating wheel 23 through the belt 33. The rotation drives the connected cutter shaft 21 to rotate through the first rotating wheel 23, and drives the connected gear 22 and the crushing cutter wheel 2 to rotate through the cutter shaft 21, and drives the adjacent gear 22 to rotate in the opposite direction through the gear 22, and drives the connected cutter shaft 21 and the crushing cutter wheel 2 to rotate through the gear 22. The two crushing cutter wheels 2 The gear 22 rotates synchronously in the opposite direction to realize the first crushing of the bio-based raw materials, and the crushed bio-based raw materials fall onto the crushing roller 31; because the gear 22 drives the connected cutter shaft 21 and the crushing cutter wheel 2 to rotate, it drives the connected first wheel 23 to rotate, and the first wheel 23 drives another second wheel 32 to rotate through the belt 33, and the second wheel 32 drives the connected roller shaft and the crushing roller 31 to rotate, and the two crushing rollers 31 rotate synchronously in the opposite direction to realize the second crushing of the bio-based raw materials, so that the bio-based raw materials are quickly crushed, and through the cooperation of the first wheel 23, the second wheel 32 and the gear 22, the crushing cutter wheel 2 and the crushing roller 31 produce a linkage function, so that the crushing cutter wheel 2 and the crushing roller 31 work synchronously.

[0029] Further, such as Figure 4 As shown, the two inner side walls of the crushing box 1 are rotatably connected to the guide plate 4 through a rotating shaft; the bottom of the guide plate 4 is fixed with two first springs 41, and the bottom of the first spring 41 is fixed to the inner side wall of the crushing box 1; the end of the guide plate 4 away from the rotating shaft is in contact with the crushing roller 31.

[0030] During operation, when the crushing rollers 31 are crushing, some of the bio-based raw materials contain moisture and will adhere to the surface of the crushing rollers 31, causing the gap between the crushing rollers 31 to become smaller or even blocked, affecting the continued crushing of the bio-based raw materials. By providing the first spring 41 and the guide plate 4, under the action of the first spring 41, the guide plate 4 is always pulled on the surface of the crushing roller 31 to scrape off the bio-based raw materials adhered to the surface of the crushing roller 31, reducing the possibility of the guide plate 4 being damaged by friction and not in contact with the crushing roller 31; at the same time, the bio-based raw materials crushed by the crushing cutter wheel 2 are drained to the middle of the two crushing rollers 31 under the action of the guide plate 4 to prevent the bio-based raw materials from scattering.

[0031] Further, such as Figure 5 and Figure 6As shown, a screening basket 5 is obliquely provided on the inner wall of the crushing box 1, and a first screen plate 51 and a second screen plate 52 are fixedly connected to the inner wall of the screening basket 5; the first screen plate 51 is arranged above the second screen plate 52, and the sieve holes opened on the first sieve plate 51 are larger than the sieve holes opened on the second sieve plate 52; one end of the first sieve plate 51 is fixedly connected to a first discharge plate 53, and one end of the second sieve plate 52 is fixedly connected to a second discharge plate 54.

[0032] During operation, a screening basket 5 is provided to screen the crushed bio-based raw materials. When the bio-based raw materials are crushed, the sizes of the crushed particles may be different due to different dryness and humidity. The sieve holes on the first sieve plate 51 are larger than the sieve holes on the second sieve plate 52. The large particles of bio-based raw materials are screened on the first sieve plate 51 and discharged through the first discharge plate 53. The medium particles of bio-based raw materials are screened on the second sieve plate 52 and discharged through the second discharge plate 54. The small particles of bio-based raw materials pass through the second sieve plate 52 and fall into the discharge hopper 55 for discharge, thereby realizing the function of quickly screening the crushed bio-based raw materials.

[0033] Further, such as Figure 5 As shown, four fixed plates 57 are fixed to the inner wall of the crushing box 1, and the tops of the fixed plates 57 are fixed with slide bars 571. The four corners of the screening basket 5 slide on the slide bars 571 respectively, and the outer sides of the slide bars 571 are sleeved with second springs 572. The two ends of the second springs 572 are fixed to the fixed plates 57 and the screening basket 5 respectively.

[0034] During operation, the crushed bio-based raw materials fall into the screening basket 5. The screening of stationary raw materials is slow. In order to screen quickly, the screening basket 5 needs to be driven. The screening basket 5 is subjected to forces in the up and down directions, so that it slides up and down on the sliding column. Under the action of the second spring 572, it keeps shaking and has a reset function, thereby accelerating the screening of the screening basket 5.

[0035] Further, such as Figure 3 and Figure 5 As shown, a second motor 56 is fixed to the outer wall of the crushing box 1, and the output shaft of the second motor 56 is rotatably connected to the crushing box 1 through a bearing. The output shaft of the second motor 56 is fixed to a rotating rod 561, and two cam blocks 562 are symmetrically fixed at both ends of the rotating rod 561. One end of the rotating rod 561 is rotatably connected to the inner wall of the crushing box 1 through a rotating shaft.

[0036] During operation, in order to drive the screening basket 5, the second motor 56 needs to be turned on. The second motor 56 drives the cam block 562 to rotate through the rotating rod 561. Due to the shape characteristics of the cam block 562, the cam block 562 drives the screening basket 5 to move up and down when rotating.

[0037] Further, such as Figure 1As shown, four pillars 11 are fixed to the bottom of the crushing box 1 . The pillars 11 are respectively arranged at the four corners of the crushing box 1 , and the bottoms of the pillars 11 are all provided with anti-slip pads.

[0038] During operation, the stability of the crushing box 1 is improved under the action of the four pillars 11, so that the crushing box 1 is convenient for crushing.

[0039] Working principle: Bio-based raw materials are put into the feed hopper 12. In order to solve the problem that the overall crushing efficiency is low due to single crushing, the raw materials pass through the crushing wheel 2 and the crushing roller 31 in the crushing box 1. By turning on the first motor 3, the first motor 3 drives the roller shaft to rotate through the output shaft, and drives the crushing roller 31 and the second rotor 32 to rotate through the roller shaft, and drives the belt 33 to rotate through the second rotor 32, and drives the first rotor 23 through the belt 33. The rotation drives the connected cutter shaft 21 to rotate through the first rotor 23, and drives the connected gear 22 and the crushing wheel 2 to rotate through the cutter shaft 21. The adjacent gear 22 rotates in the opposite direction through the gear 22, and the connected cutter shaft 21 and the crushing wheel 2 are driven to rotate through the gear 22. The two crushing wheels 2 rotate synchronously in opposite directions to achieve the first crushing of the bio-based raw materials. The crushed bio-based raw materials fall onto the crushing roller 31; because the gear 22 drives the connected cutter shaft 21 and the crushing wheel 2 to rotate, it drives the connected first rotor 23 The first rotating wheel 23 drives another second rotating wheel 32 to rotate through the belt 33, and the second rotating wheel 32 drives the connected roller and the crushing roller 31 to rotate. The two crushing rollers 31 rotate synchronously in opposite directions to achieve the second crushing of the bio-based raw materials, so that the bio-based raw materials are quickly crushed. The cooperation of the first rotating wheel 23, the second rotating wheel 32 and the gear 22 makes the crushing cutter wheel 2 and the crushing roller 31 produce a linkage function, so that the crushing cutter wheel 2 and the crushing roller 31 work synchronously; the crushed bio-based raw materials fall into the screening basket 5, and the static raw materials are screened slowly. In order to screen quickly, it is necessary to turn on the second motor 56. The second motor 56 drives the cam block 562 to rotate through the rotating rod 561. Due to the shape characteristics of the cam block 562, the cam block 562 drives the screening basket 5 to move up and down when rotating. The screening basket 5 is subjected to the up and down force, thereby sliding up and down on the sliding column. Under the action of the second spring 572, it keeps shaking and has a reset function, thereby accelerating the screening of the screening basket 5.
