[0035] The following will Figures 1-5 further elaborate on this application in conjunction with the attached drawings.

[0036] The embodiment of this application discloses a device for secondary shredding of raw materials.

[0037] Embodiment 1

[0038] Referring to Figure 1 , a device for secondary shredding of raw materials includes a shredder housing 1. The side wall of the shredder housing 1 is fixedly connected to one end of the extension platform 11 close to the shredder housing 1. The top of the shredder housing 1 is fixedly connected to the bottom of the pulverizing cylinder 12. The top of the pulverizing cylinder 12 is fixedly connected to the bottom of the feed inlet 13. The feed inlet 13 is vertically penetrated through the inside of the pulverizing cylinder 12. The pulverizing cylinder 12 is vertically penetrated through the inside of the shredder housing 1. A shredding structure 2 is arranged inside the shredder housing 1, and a multi-stage transmission structure 3 is arranged inside the shredder housing 1.

[0039] Through the above settings, the staff places the shredder housing 1 at a specified position, and then connects the extension platform 11 to the shredder housing 1 for subsequent shredding work.

[0040] Referring to Figure 2 , 3, the shredding structure 2 includes a rotating rod 23 that movably penetrates the side wall of the pulverizing cylinder 12. The rotating rod 23 movably penetrates both sides of the pulverizing cylinder 12, so that the pulverizing cylinder 12 limits the rotating rod 23. The outer wall of the rotating rod 23 located inside the pulverizing cylinder 12 penetrates through the middle of the shredding blade 26 and is fixedly connected to the shredding blade 26, so as to perform shredding treatment through the shredding blade 26. The shredding structure 2 further includes a first motor 21 fixedly connected to the top of the extension platform 11. The output shaft end of the first motor 21 close to the pulverizing cylinder 12 penetrates through the middle of the first pulley 22, so that the output shaft end of the first motor 21 close to the pulverizing cylinder 12 is fixedly connected to the first pulley 22. One end of the rotating rod 23 close to the first motor 21 penetrates through the middle of the second pulley 24, so that the rotating rod 23 is fixedly connected to the second pulley 24. A conveyor belt 25 is sleeved on the outer walls between the first pulley 22 and the second pulley 24, so as to facilitate synchronous transmission of the first pulley 22 and the second pulley 24 through the conveyor belt 25.

[0041] With the above settings, the staff starts Motor 1 21. Subsequently, the output shaft end of Motor 1 21 will drive Pulley 1 22 to rotate. Pulley 1 22 will drive Conveyor Belt 25 to transmit power. Conveyor Belt 25 will drive Pulley 2 24 to rotate. Pulley 2 24 will drive Rotating Rod 23 to rotate. Rotating Rod 23 will drive Shredding Blade 26 to rotate. Shredding Blade 26 will shred the raw materials falling from the top of Feeding Port 13. After the raw materials are shredded in Crushing Cylinder 12, they will fall into Shredder Housing 1.

[0042] Referring to Figure 4 , 5, the multi-stage transmission structure 3 includes a driving rotating rod 36. The driving rotating rod 36 passes through the middle of the driving turntable 37, so that the driving rotating rod 36 is fixedly connected to the driving turntable 37. A crawler 38 is sleeved on the outer wall of the driving turntable 37. The multi-stage transmission structure 3 further includes a support bar 31 fixedly connected to the bottom of the inner wall of the shredder housing 1. The top of the support bar 31 is fixedly connected to the bottom of the support frame 32. The support frame 32 is inclined as a whole. The top of the support frame 32 is fixedly connected to the bottom of the limiting bar 33. The top of the support frame 32 is fixedly connected to the bottom of the connecting bar 34. The top of the connecting bar 34 is fixedly connected to the top of the inner wall of the shredder housing 1. The top of the support frame 32 is fixedly connected to the bottom of the support plate 35. A circular through hole is formed through the side wall of the support plate 35. The driving rotating rod 36 movably passes through the circular through hole formed through the side wall of the support plate 35, so that the driving rotating rod 36 is rotatably connected to the support plate 35. A circular through hole is formed through the side wall of the connecting bar 34. The supporting rotating rod 39 movably passes through the circular through hole formed through the side wall of the connecting bar 34, so that the connecting bar 34 is rotatably connected to the supporting rotating rod 39. A circular through hole is formed through the side wall of the limiting bar 33. The supporting rotating rod 39 is rotatably connected to the circular through hole formed through the side wall of the limiting bar 33, so that the supporting rotating rod 39 is rotatably connected to the limiting bar 33. One side wall of the support frame 32 away from the shredder housing 1 is fixedly connected to the side wall of the carrying plate 310. The top of the carrying plate 310 is fixedly connected to the bottom of the second motor 311. The output shaft end of the carrying plate 310 is fixedly connected to one end of the driving rotating rod 36 close to the carrying plate 310. Thus, the driving rotating rod 36 is driven to rotate by the second motor 311. One end of the support frame 32 away from the shredder housing 1 is fixedly connected to one end of the blanking plate 312 close to the support frame 32. The bottom of the support frame 32 is fixedly connected to the top of the vertical support column 313. The bottom of the vertical support column 313 is fixedly connected to the top of the support bottom plate 314, so as to ensure the overall stability of the multi-stage transmission structure 3.

[0043] With the above settings, when the raw material is shredded and completed, it will fall to the top of the track 38 inside the shredder housing 1. At this time, the operator has started the first motor 21, and the output shaft end of the first motor 21 will drive the shredding blade 26 to rotate. The shredding blade 26 will drive the driving turntable 37 to rotate, and the driving turntable 37 will drive the track 38 to circulate and transmit. The track 38 will drive the once-shredded raw material on the top of the track 38 to climb and transmit to the side away from the shredder housing 1. When the once-shredded raw material climbs to the highest point along with the transmission of the track 38, it will fall to the top of the feeding plate 312, and then fall to the top of the second track 38, causing the transmission direction to turn 90 degrees. When it is transmitted to the top along with the second track 38, it will fall to the top of the third track 38 again and turn 90 degrees again. When it is transmitted to the top along with the third track 38, it will fall to the top of the fourth track 38 again and turn 90 degrees again. At this time, along with the transmission of the fourth track 38, the once-shredded raw material will be transmitted to the top of the feeding port 13 again and guided by the feeding plate 312 on the top of the feeding port 13 to fall into the feeding port 13, so that the once-shredded raw material enters the shredding structure 2 again to complete secondary shredding.

[0044] The implementation principle of a raw material secondary shredding device in an embodiment of the present application is as follows: the first motor 21 drives the rotating rod 23 to rotate, and then the rotating rod 23 drives the shredding blade 26 to rotate to complete the shredding of the raw material. The second motor 311 drives the driving rod 36 to rotate, the driving rod 36 drives the driving turntable 37 to rotate, and then the driving turntable 37 drives the track 38 to transmit. Thus, through the transmission of multiple tracks 38, the once-shredded raw material enters the feeding port 13 again and is shredded by the shredding structure 2 to complete secondary shredding.

[0045] Among them, the first motor 21 and the second motor 311 are prior arts, and their structural principles will not be described in detail.

[0046] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
