[0028] The sieve plate 2 is used to screen out small particles (dust, iron filings, rust, etc.) in the scrap iron and steel fragments to prevent the small particles from being discharged together with the scrap iron and steel fragments after screening, and secondary processing is required, which is time-consuming and labor-intensive. The sieve plate 2 is slidably connected to the inside of the screening box 1. The input end of the sieve plate 2 is located below the feed port 11, and is used to receive the scrap iron and steel fragments input from the feed port 11. The output end of the sieve plate 2 extends downwardly away from the feed port 11, that is, the sieve plate 2 is inclined. By tilting the sieve plate 2, the scrap iron and steel fragments are fully dispersed when sliding down from the upper end to form a thin material layer, which prevents the scrap iron and steel fragments from accumulating and is conducive to subsequent screening.

[0029] A conveying assembly 6 is provided at the lower part of the screening box 1, below the output end of the screen plate 2, for sorting metal waste and non-metal waste of scrap steel.

In this embodiment, the conveying assembly 6 includes a plurality of drive rollers 61, a plurality of electromagnetic rollers 62 and a conveyor belt 63, the conveyor belt 63 is wound around the outside of the plurality of drive rollers 61 and the plurality of electromagnetic rollers 62, the plurality of electromagnetic rollers 62 are located above the partition 12, the plurality of drive rollers 61 are located below the output end of the screen plate 2, and a first motor 64 for driving any one of the drive rollers 61 is fixed on one side of the screening box 1.

[0030] During implementation, the scrap steel fragments falling from the output end of the screen plate 2 fall onto the conveyor belt 63 of the conveying assembly 6, and the first motor 64 drives the driving roller 61 to rotate, and at the same time drives the electromagnetic roller 62 to be driven, so that the conveyor belt 63 drives the scrap steel fragments to move from the driving roller 61 to the electromagnetic roller 62, so that the electromagnetic roller 62 absorbs the metal waste, and the non-metal waste falls into the non-metallic containing area 14 through the output end of the conveyor belt 63. At this time, the electromagnetic roller 62 continues to absorb the steel waste particles and moves them to the metal containing area 13. When the steel waste particles move out of the adsorption range of the electromagnetic roller 62, the metal waste falls into the metal containing area 13 to complete the separation of metal waste and non-metal waste of the scrap steel fragments.

[0031] The receiving plate 3 is slidably connected inside the screening box 1 and is located below the screen plate 2, and is used to receive the small particles screened by the screen plate 2. One side of the screening box 1 is connected to a collection box 7, and the bottom end of the receiving plate 3 extends into the collection box 7, that is, the receiving plate 3 can discharge the small particles screened by the screen plate 2 into the collection box 7 for collection. A box door 8 for opening or closing the collection box 7 is provided on one side of the collection box 7. In this embodiment, the receiving plate 3 is inclined, and the inclination direction of the receiving plate 3 is opposite to the inclination direction of the screen plate 2, so that the small particles slide into the collection box 7 along the top surface of the inclined receiving plate 3.

That is, the free end of the connecting rod 21 is slidably connected inside the U-shaped chutes 15, so as to realize the sliding connection between the screening plate 2 and the receiving plate 3 and the side wall of the screening box 1.

[0033] The internal rotation of the screening box 1 is connected with a vibration assembly 5, which is used to drive the receiving plate 3 to slide up and down along the U-shaped chute 15, so that the receiving plate 3 can vibrate up and down, and the small particles can be quickly slid into the collecting box 7 by vibration, which is convenient for collecting the small particles. The vibration assembly 5 includes a shaft rod 51 and a push rod 52, the shaft rod 51 is arranged below the receiving plate 3, and the two ends of the shaft rod 51 are respectively connected to the inner wall of the screening box 1.

During implementation, the power unit 53 drives the shaft 51 to rotate, and the push rod 52 rotates along the axial direction of the shaft 51. When the free end of the push rod 52 rotates to the bottom of the receiving plate 3, it abuts against the bottom of the receiving plate 3, and then pushes the receiving plate 3 upward, so that the receiving plate 3 slides upward along the U-shaped chute 15. The push rod 52 continues to rotate, and the free end of the push rod 52 moves away from the receiving plate 3, that is, the free end of the push rod 52 no longer pushes the receiving plate 3, and the receiving plate 3 is reset by its own gravity. That is, the receiving plate 3 slides up and down once, and the power unit 53 continuously drives the shaft 51 to rotate, so that the receiving plate 3 slides up and down quickly along the U-shaped chute 15 to produce a vibration effect, so that the small particles quickly slide into the collecting box 7, which is convenient for collecting the small particles.

[0035] The power unit 53 can be driven by a motor, that is, the output end of the motor is fixedly connected to one end of the shaft 51 to drive the shaft 51 to rotate.

The first transmission wheel 531 and the second transmission wheel 532 are driven by a belt 533. In this way, there is no need to add other power, so that the first motor 64 drives the transmission component 6 and the vibration component 5 to rotate at the same time.

The push assembly 4 includes a sleeve 41, a slide bar 42 and a compression spring 43, the sleeve 41 is fixed on the top surface of the receiving plate 3, the slide bar 42 is arranged on the bottom surface of the sieve plate 2 corresponding to the sleeve 41, and the bottom end of the slide bar 42 is slidably arranged in the sleeve 41, and the compression spring 43 is sleeved on the outside of the sleeve 41, and the two ends of the compression spring 43 are respectively in contact with the sieve plate 2 and the receiving plate 3. During implementation, the vibration assembly 5 drives the side of the receiving plate 3 close to the output end of the sieve plate 2 to slide up and down, and at the same time, the push assembly 4 drives the output end of the sieve plate 2 to slide up and down along the U-shaped slide groove 15, so that the vibration assembly 5 can simultaneously drive the receiving plate 3 and the sieve plate 2 to slide up and down. Preferably, there are multiple pushing assemblies 4, and the multiple pushing assemblies 4 are evenly arranged along the axial direction of the vibration assembly 5, so that the connection between the receiving plate 3 and the screen plate 2 is more stable.

[0037] During the specific implementation of the utility model, the staff puts the scrap iron and steel fragments into the feed port 11, and the scrap iron and steel fragments first fall onto the screen plate 2. The screen plate 2 and the receiving plate 3 on the side close to the output end of the screen plate 2 are vibrated up and down through the vibration component 5 and the push component 4, so that the materials are fully dispersed when sliding down to form a thin material layer to prevent material accumulation, which is beneficial to subsequent screening. At the same time, small particles in the scrap iron and steel fragments are screened out and discharged into the collecting box 7. The screen plate 2 discharges the scrap iron and steel fragments onto the conveying component 6. The conveying component 6 absorbs the metal objects through the electromagnetic roller 62 to separate the crushed fragments into metal materials and non-metal materials, and discharge them to the metal containing area 13 and the non-metal containing area 14 respectively, and finally completes the classification of the scrap iron and steel.
