[0033] The feed frame 4 is used to transport large pieces of material to between the high manganese steel bracket 3 and the stamping assembly 6. The support base 2 cooperates with the high manganese steel bracket 3 to support large pieces of hard material. The stamping assembly 6 cooperates with the high manganese steel bracket 3 to impact and crush the hard material. The scraper assembly 7 is used to clean the working surface fragments of the stamping assembly 6 and the high manganese steel bracket 3. The feeding assembly 8 cooperates with the feed frame 4 to stably transport the large and small particle fragments after coarse crushing to the fine crushing assembly 9. The fine crushing assembly 9 is used to efficiently crush the fragments.

[0034] This product realizes sealed crushing operation through the horizontal material storage frame 16, the sealed shell 10 and the high manganese steel bracket 3, so that the large pieces of hard materials are always located between the high manganese steel bracket 3 and the crushing stamping plate 13, and the square push plate 19 fits between the high manganese steel bracket 3 and the crushing stamping plate 13 and moves back and forth. Under the support of elastic force, the scraper sheet 20 scrapes the material between the high manganese steel bracket 3 and the crushing stamping plate 13 and sweeps it to the feeding pipe rack 5, thereby ensuring the discharge volume.

[0035] The stamping assembly 6 includes a sealed shell 10, a heavy-duty oil cylinder 11, a guide column 12, a crushing stamping plate 13, a connecting steel plate 14 and a linear shaft 15. The heavy-duty oil cylinder 11 is installed in the middle of the top of the sealed shell 10. The guide column 12 passes through the inner side of the top of the sealed shell 10 and is fixedly connected to the output end of the heavy-duty oil cylinder 11.

[0038] Reverse start the heavy oil cylinder 11 and lift up the crushing punching plate 13. After coarse crushing, there will be crushed materials pressed on the working surface of the high manganese steel bracket 3 and the crushing punching plate 13. At this time, start the pushing cylinder 17 at one end to push the square pushing plate 19 to move to the gap between the high manganese steel bracket 3 and the crushing punching plate 13. Since the compression spring 35 inside the through hole 33 is always in a compressed state, the scraper sheet 20 repeatedly scrapes the crushed materials on the working surface of the high manganese steel bracket 3 and the crushing punching plate 13 under the reaction of the elastic force, and pushes the material into the feeding pipe rack 5 under the pumping state to complete the feeding operation.

[0040] The DC motor 22 outside the support frame 21 is started to drive the driving roller 23, and the driving roller 23 drives the material-pickup piece 24 welded on the outer wall to rotate rapidly. The multiple groups of material-pickup pieces 24 rotating in one direction push the material from the top of the feeding pipe rack 5 to the crushing box 25 to prevent the material from being blocked at the pipe mouth.

[0041] The fine crushing assembly 9 includes a crushing box 25, a trapezoidal feed frame 26, a movable crushing plate 27, a baffle 28 and crushing teeth 29. The trapezoidal feed frame 26 is fixedly connected to the outside of the crushing box 25.

The movable crushing plate 27 is slidably connected to the inside of the crushing box 25. The baffle 28 is installed on the outside of the top of the movable crushing plate 27 located below and is used to guide the crushed material.

[0042] A vertical vibration motor 30 , a vibration exciter 31 and a seismic isolation spring 32 are also provided on the surface of the movable particle board 27 . The vertical vibration motor 30 is installed on the inner side of the particle box 25 , the vibration exciter 31 is installed above the output end of the vertical vibration motor 30 , and the seismic isolation spring 32 is arranged in a circular array on the periphery of the vertical vibration motor 30 .

[0043] After the material enters the crushing box 25, it falls on the slope of the inclined trapezoidal feeding frame 26. Then the vertical motor is started. The vertical vibration motor 30 is used as the power source. The vibration force is transmitted to the movable crushing plate 27 through the exciter 31, causing it to vibrate. The crushing teeth 29 of the movable crushing plate 27 are meshed with the crushing teeth 29 on the trapezoidal feeding frame 26, and repeatedly impact the material during the high-frequency vibration process to achieve the purpose of re-crushing the material. The finely crushed material falls along the baffle 28 into the movable crushing plate 27 below, and then is shaken out of the crushing box 25 through high-frequency shaking. Finally, the belt conveyor 37 is used to complete the transportation of the fine material and facilitate unified collection, thereby achieving the purpose of integrated coarse and fine crushing of this product.

[0044] The interior of the square push plate 19 is also provided with a through hole 33, a telescopic rod 34 and a compression spring 35. The compression spring 35 is arranged on the inner side of the through hole 33, and the two sides of the compression spring 35 are fixedly connected to the opposite side surfaces of the scraper plate 20, and the telescopic rod 34 is installed on the inner side of the compression spring 35.

[0045] A through hole 36 matching the size of the linear shaft 15 is also formed inside the connecting steel plate 14 .

[0046] A belt conveyor 37 is also provided below the discharge end of the crushed material box 25 .

[0047] Working principle: large pieces of hard materials are put into the support base 2 and the high manganese steel bracket 3 through the feed frame 4. When crushing, the heavy oil cylinder 11 on the top is started, and its piston end pushes the guide column 12 and drives the crushing punching plate 13 to complete the lifting.

At this time, the pushing cylinder 17 at one end is started to push the square pushing plate 19 to move to the gap between the high manganese steel bracket 3 and the crushing punching plate 13. Since the compression spring 35 inside the through hole 33 is always in a compressed state, the scraper sheet 20 repeatedly scrapes the crushed materials on the working surface of the high manganese steel bracket 3 and the crushing punching plate 13 under the reaction of the elastic force, and pushes the material into the feeding pipe rack 5 under the pumping state to complete the feeding operation. Then, the DC motor 22 on the outside of the support frame 21 is started to drive the driving roller 23. The driving roller 23 drives the material-pickup piece 24 welded on the outer wall to rotate rapidly. The multiple sets of material-pickup pieces 24 rotating in one direction push the material from the top of the feeding pipe frame 5 to the crushing box 25 to prevent the material from being blocked at the pipe mouth; after the material enters the crushing box 25, it falls on the slope of the trapezoidal feeding frame 26 with an inclined structure, and then the vertical motor is started. The vertical vibration motor 30 is used as a power source to transmit the vibration force to the movable crushing plate 27 through the exciter 31 to make it vibrate. The crushing teeth 29 of the movable crushing plate 27 are meshed with the crushing teeth 29 on the trapezoidal feeding frame 26, and repeatedly impact the material during the high-frequency vibration process to achieve the purpose of re-crushing the material. The crushed material falls along the baffle 28 into the movable crushing plate 27 below, and then is shaken out of the crushing box 25 after high-frequency shaking. Finally, the transportation of the fine material is completed through the belt conveyor 37 and it is convenient for unified collection, thereby achieving the purpose of integrated coarse and fine crushing of this product.
