[0032] With reference to Figure 1 - Figure 3The crushing mechanism comprises a crushing assembly and a screening assembly. The crushing assembly comprises a motor 31. The motor 31 is a prior art and can be implemented by those skilled in the art. Therefore, the motor 31 is not described in detail in this case. The output shaft of the motor 31 is fixedly connected with a crushing roller one 32. The front end of the outer wall of the crushing roller one 32 is fixedly connected with a gear one 33. The front surface of the feeding box 2 is penetrated and rotationally connected with a crushing roller two 34. The crushing roller one 32 and the crushing roller two 34 are staggered. The crushing sections of the crushing roller one 32 and the crushing roller two 34 are located in the feeding box 2 and can avoid the existence of large gaps. The front section of the outer wall of the crushing roller two 34 is fixedly connected with a gear two 35. The gear one 33 and the gear two 35 are of the same model. The screening assembly comprises a fixed block 45. The fixed block 45 is elastically connected with a T-shaped block 42 through a compression spring 44. The upper surface of the T-shaped block 42 is fixedly connected with a positioning block 43. The front end of the outer wall of the crushing roller two 34 is fixedly connected with a pushing block 41. The pushing block 41 will move circularly with the rotation of the crushing roller two 34. When the pushing block 41 moves circularly, the positioning block 43 will be pressed. The upper surface of the T-shaped block 42 is fixedly connected with a screen plate 46 for screening steel slag raw materials.

[0033] With reference to Figure 1 , Figure 4 The cleaning assembly comprises a fixed plate 51. The fixed plate 51 is elastically connected with a moving plate 53 through a connecting spring 52. The upper surface of the moving plate 53 is fixedly connected with a brush 54. The brush 54 is made of flexible material but has certain toughness. When the brush 54 is pressed by a large force, it will be deformed.

[0034] With reference to Figure 1 - Figure 3 The motor 31 is arranged on the rear surface of the feeding box 2. The feeding box 2 supports the motor 31. The crushing roller one 32 penetrates and is rotationally connected to the front surface of the feeding box 2. The gear one 33 and the gear two 35 are engaged. The crushing roller one 32 and the crushing roller two 34 rotate in opposite directions, which can crush and scatter the steel slag raw materials. The rear surface of the fixed block 45 is fixedly connected to the front surface of the feeding box 2. The T-shaped block 42 penetrates and is slidingly connected to the front surface of the feeding box 2. The T-shaped block 42 can block the opening of the front surface of the feeding box 2, which can prevent the steel slag raw materials from leaking out. The T-shaped block 42 moves longitudinally. When the T-shaped block 42 moves to the highest point, the screen plate 46 will not contact the crushing roller one 32 and the crushing roller two 34. The right end of the upper surface of the positioning block 43 is arranged as an inclined surface. When the inclined surface is pressed, the positioning block 43 will move downward. One end of the compression spring 44 is fixedly connected to the lower surface of the T-shaped block 42. The other end of the compression spring 44 is fixedly connected to the upper surface of the fixed block 45. When the T-shaped block 42 moves downward, the compression spring 44 will be pressed to generate a reaction force. The screen plate 46 is slidingly connected to the inner wall of the feeding box 2. The upper surface of the screen plate 46 is provided with a filtering groove, which can block the steel slag raw materials with large volume and prevent the steel slag raw materials with large volume from being effectively separated from the iron by the magnetic separator 6.

[0035] Referring to Figure 1 , Figure 4 , The fixed plate 51 is fixedly connected to the inner wall of the conveyor 1, one end of the connecting spring 52 is fixedly connected to the upper surface of the fixed plate 51, the other end of the connecting spring 52 is fixedly connected to the lower surface of the moving plate 53, the moving plate 53 is slidingly connected to the inner wall of the conveyor 1, when the moving plate 53 moves downward, it will press the connecting spring 52 to generate a reaction force, which can avoid the brush 54 from scratching the conveyor 1, the moving plate 53 and the fixed plate 51 are connected to the support on the conveyor 1, the upper surface of the brush 54 is in contact with the lower surface of the conveyor 1, and the upper surface of the brush 54 is in contact with the conveying belt on the conveyor 1.

[0036] Working principle: when the device is used, the steel slag raw materials are placed on the conveyor 1, then the conveyor 1, the motor 31 and the magnetic separator 6 are started, after the conveyor 1 is started, the steel slag raw materials are conveyed into the discharge bin 2, when the motor 31 is started, the crushing roller one 32 is driven to rotate, and under the transmission of the gear one 33 and the gear two 35, the crushing roller two 34 is also rotated, the rotating crushing roller one 32 and the crushing roller two 34 can scatter and crush the steel slag raw materials.

[0037] The scattered and crushed steel slag raw materials fall on the sieve plate 46, and the qualified ones pass through the filter groove into the magnetic separator 6 to separate the iron in the steel slag raw materials for subsequent use.

[0038] The unqualified ones are blocked, when the crushing roller two 34 rotates, the push block 41 moves in a circle, when the push block 41 moves in a circle, it presses the inclined surface of the positioning block 43, thereby driving the positioning block 43, the T-shaped block 42 and the sieve plate 46 to move downward, the downward moving T-shaped block 42 presses the compression spring 44 to generate a reaction force, the pressing of the push block 41 on the positioning block 43 is intermittent, so the reaction force of the compression spring 44 drives the positioning block 43, the T-shaped block 42 and the sieve plate 46 to vibrate longitudinally, which can scatter and crush the steel slag, and the scattered steel slag is crushed again by the crushing roller two 34 and the crushing roller one 32, until the crushing is qualified, the steel slag passes through the filter groove into the magnetic separator 6 to separate the iron in the steel slag.

[0039] During the operation of the conveyor 1, the surface will adhere to the steel slag raw materials, which will be swept off when passing through the brush 54, facilitating subsequent recycling and reuse.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
