[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a crushing device for shale brick production includes a crushing barrel 10. A second discharge port 36 is provided on the lower end face of the crushing barrel 10. Two first crushing rollers 11 are rotatably arranged inside the crushing barrel 10. A first guide plate 13 is provided above each first crushing roller 11 on the inner wall of the crushing barrel 10. A first motor 12 is provided on one side of each first crushing roller 11 on the outer wall of the crushing barrel 10. The first motor 12 is a conventional motor, which is existing technology. The first motor 12 is an adjacent... The rotation of the first crushing roller 11 provides power. A screen plate 15 is inclinedly arranged below the first crushing roller 11. The two ends of the screen plate 15 are respectively provided with a first discharge port 14 and a maintenance window 23 on the inner side wall of the crushing barrel 10. A sealing plate 17 is detachably arranged on the maintenance window 23. The end of the screen plate 15 near the first discharge port 14 is rotatably connected to the two side walls of the first discharge port 14. An elastic sealing cloth 22 is connected between the screen plate 15 and the sealing plate 17. A secondary crushing component is arranged below the screen plate 15.

[0032] Specifically, the screen plate 15 is rotatably connected to the inside of the first discharge port 14 through a long shaft bolt 16. By disassembling the long shaft bolt 16, the screen plate 15 can be disassembled, which provides convenience for the maintenance of the subsequent screen plate 15. The size of the holes on the screen plate 15 can be adaptively set according to the specific size of the raw material particles of the secondary crushing assembly. The stone particles exceeding the diameter of the screen holes on the screen plate 15 are discharged from the inside of the first discharge port 14 through the inclined arrangement of the screen plate 15 and are crushed again by the secondary feeding of workers.

[0033] The elastic sealing cloth 22 is made of Lycra fabric and has high elasticity and wear resistance. The arrangement of the elastic sealing cloth 22 effectively avoids the direct falling of some stone blocks from the gap between one end of the screen plate 15 and the side wall of the crushing barrel 10 into the inside of the secondary crushing assembly. The elastic sealing cloth 22 cooperates with the screen plate 15 to intercept the raw material particles crushed by the two first crushing rollers 11 and performs screening through the screen plate 15. At the same time, under the elastic tension of the elastic sealing cloth 22 itself, when the raw material particles crushed by the two first crushing rollers 11 fall to the upper end surface of the screen plate 15, the raw material particles form an impact on the upper end surface of the screen plate 15 under the action of their own gravity, causing the screen plate 15 to rotate. At this time, one end of the screen plate 15 will stretch the elastic sealing cloth 22. Under the action of the elastic tension of the elastic sealing cloth 22 itself, the elastic sealing cloth 22 elastically deforms, thereby driving one end of the screen plate 15 to repeatedly vibrate up and down, and thus the screening effect of the screen plate 15 on the raw material particles is increased, and the crushing efficiency of the device is improved.

[0034] The maintenance window 23 and the sealing plate 17 are connected through bolts, and the sealing plate 17 can also be disassembled through the connecting bolts. When the inside of the subsequent device fails and needs to be maintained, the sealing plate 17 can be opened to maintain the inside of the device through the maintenance window 23.

[0035] The sealing plate 17 is also provided with a handle 35 on one side wall, which facilitates the holding of the sealing plate 17 when it is disassembled.

[0036] Further, as shown in Figure 3 、 Figure 6 and Figure 7 , the secondary crushing assembly includes two second crushing rollers 24 rotatably arranged below the screen plate 15. Long slot holes 26 are arranged on the side walls of the crushing barrel 10 on both sides of each second crushing roller 24. A rotating shaft 25 is slidably arranged in each long slot hole 26, and each rotating shaft 25 is fixedly connected to one side wall of the adjacent second crushing roller 24.

[0037] Specifically, each long slot hole 26 limits the horizontal movement of the sliding shaft 25 inside it, further forming a horizontal sliding limit for the two second crushing rollers 24, which can ensure the normal rotation of the second crushing rollers 24 and the crushing effect on the raw material particles when adjusting the distance between the two second crushing rollers 24.

[0038] Further, as shown in Figure 3 and Figure 5 , the upper side of each second crushing roller 24 is provided with a second guide plate 32 on the inner side wall of the crushing barrel 10, and the lower end surface of each second guide plate 32 is provided with an arc-shaped scraper 33, and each arc-shaped scraper 33 is in abutment with the outer circular surface of the adjacent second crushing roller 24.

[0039] Specifically, the second guide plate 32 is provided to form a barrier for the raw material particles falling from the top of the two second crushing rollers 24, preventing the raw material particles from directly falling from the gap between the second crushing roller 24 and the crushing barrel 10 to the outside of the device, thereby causing the overall produced raw material particles to not meet the requirements.

[0040] The arc-shaped scraper 33 is made of elastic material, and the shape of the arc-shaped scraper 33 is shown in Figure 5 , which is a quarter of a circle, and the lower end is in the shape of an inclined blade. The arc-shaped scraper 33 forms a close abutment with the outer circular surface of the second crushing roller 24 through its elastic deformation, and the lower end of the arc-shaped scraper 33 scrapes the raw material particles adhering to the outer circular surface of the second crushing roller 24 while the second crushing roller 24 is rotating, so that the crushing effect of the second crushing roller 24 on the raw material particles is improved.

[0041] Further, as shown in Figure 5 , a plurality of elastic flaps 34 are provided on one side of each arc-shaped scraper 33 between the arc-shaped scraper 33 and the crushing barrel 10.

[0042] Specifically, after the distance between the two second crushing rollers 24 is reduced, the contact tightness between the outer circular surface of the second crushing roller 24 and the arc-shaped scraper 33 gradually decreases, and through the provision of the plurality of elastic flaps 34, abutment support is formed on one end of the arc-shaped scraper 33, thereby ensuring the scraping effect of the arc-shaped scraper 33 on the outer circular surface of the second crushing roller 24.

[0043] Further, as shown in Figure 1 and Figure 6As shown, the outer part of each two adjacent rotating shafts 25 is provided with a fixed frame 27 on the outer side wall of the crushing barrel 10, the inner part of each fixed frame 27 is slidingly provided with two sliding blocks 28, each sliding block 28 is rotationally connected with its adjacent rotating shaft 25, the inner part of each fixed frame 27 is connected with a plurality of springs 29 between the two sliding blocks 28, one side of each sliding block 28 is rotationally provided with a threaded rod 30 on the side wall of the fixed frame 27, one end of each threaded rod 30 is rotationally abutted with one side wall of its adjacent sliding block 28, one side of each fixed frame 27 is provided with a second motor 31, the two second motors 31 respectively provide power for the rotation of the two second crushing rollers 24, the output end of each second motor 31 is respectively fixedly connected with one end of its adjacent rotating shaft 25, and each second motor 31 is respectively fixedly connected with the outer side wall of its adjacent sliding block 28.

[0044] Specifically, the outer circular surface of the threaded rod 30 is provided with threads, by rotating the threaded rod 30, one end of the threaded rod 30 forms abutment with the side wall of the sliding block 28, and drives the sliding block 28 to move close to the other sliding block 28, by the arrangement of the fixed frame 27, the horizontal sliding of the sliding block 28 can be limited, by the arrangement of the plurality of springs 29, the elastic support of the two sliding blocks 28 can be formed, when the threaded rod 30 is reversely rotated, under the action of the elastic tension of the plurality of springs 29, the sliding block 28 is driven to tightly contact with one end of the threaded rod 30, the distance between the two sliding blocks 28 is increased, and the distance between the two first discharge ports 14 is adjusted, thereby effectively increasing the practicability of the device.

[0045] By arranging the two second motors 31 on one side of the two fixed frames 27, when the distance between the two second crushing rollers 24 is adjusted, the collision between the two second motors 31 is avoided, the second motor 31 is a common motor, which is prior art, the output end of the second motor 31 drives the second crushing roller 24 to rotate, thereby forming secondary crushing of the raw material particles.

[0046] Further, as shown in the drawings, Figure 4 The second clamping groove 20 is arranged between the sieve plate 15 and the elastic sealing cloth 22 on one side wall of the sieve plate 15, the second clamping groove 20 is slidingly provided with a second clamping block 21 inside, the side wall of the sealing plate 17 is provided with a first clamping groove 18, the first clamping groove 18 is slidingly provided with a first clamping block 19 inside, and the two ends of the elastic sealing cloth 22 are respectively fixedly connected with the first clamping block 19 and the second clamping block 21.

[0047] Specifically, the first clamping groove 18, the first clamping block 19, the second clamping groove 20, the second clamping block 21 and the length of the elastic sealing cloth 22 are the same as the width of the inner side wall of the crushing barrel body 10, the first clamping block 19 and the second clamping block 21 form the stretching and flattening effect of the elastic sealing cloth 22, and ensure the sealing effect of the elastic sealing cloth 22 on the gap between the sieve plate 15 and the crushing barrel body 10.

[0048] Through the clamping cooperation of the first clamping groove 18 and the first clamping block 19 and the second clamping groove 20 and the second clamping block 21, the replacement of the elastic sealing cloth 22 is facilitated. When replacing, the sealing plate 17 can be first disassembled from the maintenance window 23, then the first clamping block 19 is disassembled from the inside of the first clamping groove 18, then the long shaft bolt 16 is disassembled, at this time the sieve plate 15 can be taken out from the inside of the crushing barrel body 10, and then the second clamping block 21 is taken out from the inside of the second clamping groove 20, so as to replace the elastic sealing cloth 22.

[0049] When shale bricks need to be crushed, first, the shale brick raw materials are poured into the inside of the crushing barrel body 10 from the upper port, the two first motors 12 are started, the output end of the first motor 12 drives the first crushing roller 11 to rotate, forming the first crushing of the raw materials, the crushed raw materials fall onto the upper end face of the sieve plate 15, and the raw materials with larger particles are discharged from the first discharge port 14 through the screening of the sieve plate 15 and are poured into the inside of the crushing barrel body 10 again for further crushing by the worker.
