In the utility model, the side plate moves through the work of the vibration motor, the spring deforms through the movement of the side plate, at the same time, the movement of the side plate drives the slider to slide inside the chute, and the movement of the side plate drives the sieve plate to move.

[0004] During the crushing process of the scrap steel in the scrap steel crushing device with this publication number, the crushed steel is screened by setting a vibratable sieve plate. The crushed steel that meets the crushing standard will fall and be discharged through the sieve mesh, while some crushed steel that does not meet the crushing standard will remain on the sieve plate. Since the sieve plate and the side plate are integrally fixed and the side plate is slidably connected in the screening box, it is more troublesome to discharge the unqualified crushed steel screened out on the sieve plate, and the sieve plate is not convenient to replace. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a scrap steel rolling and crushing device, which has the advantages of being convenient to discharge the unqualified crushed steel screened out on the sieve plate, etc.

[0016] The scrap steel rolling and crushing device, by setting a screening component, after the scrap steel is crushed and discharged from the discharge port, it will enter the housing and fall onto the top of the sieve plate. By driving the cam to rotate with the motor, the housing can be pushed up and down, so that the crushed steel on the sieve plate can be quickly screened. The qualified crushed steel will be discharged from the discharge hopper, and the unqualified crushed steel will remain on the top of the sieve plate. After the qualified crushed steel is discharged, open the box door. After the limiting member is rotated upward and removed from the surface of the slider, the handle can be pulled to withdraw the sieve plate from the housing, so that the unqualified crushed steel on the top of the sieve plate can fall, thus facilitating the discharge of the unqualified crushed steel.

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , a scrap steel rolling and crushing device in this embodiment includes a base 1. A screening box 2 is fixedly installed on the top of the base 1. A crusher housing 3 is embedded and fixed on the top of the screening box 2. A crushing mechanism is arranged inside the crusher housing 3. A discharge port 9 is opened at the bottom of the crusher housing 3. A screening component is arranged inside the screening box 2.

[0024] The screening assembly includes a housing 8. A groove 15 is formed at the bottom of the front surface of the housing 8. Inside the housing 8, sliding grooves 14 are formed on the left and right sides of the groove 15. A slider 13 is slidably connected inside the sliding groove 14. A sieve plate 10 is fixedly connected between the two sliders 13. A plurality of sieve holes are formed inside the sieve plate 10. A handle is fixed on the front surface of the sieve plate 10. The sieve plate 10 is in fit with the inner wall of the housing 8. Movable blocks 16 are fixedly connected to both the left and right sides of the housing 8. Installation grooves are formed on the inner side walls of the left and right sides of the screening box body 2. A sliding rod 17 is fixedly connected inside the installation groove. The movable block 16 is slidably connected to the outside of the sliding rod 17. The movable block 16 is slidably connected inside the installation groove. A spring 18 installed on the top of the movable block 16 is sleeved on the outside of the sliding rod 17.

[0025] A driving member is arranged on the side wall of the screening box body 2. The driving member includes two motors 19. The two motors 19 are respectively fixedly installed on the left and right side walls of the screening box body 2. The output shaft of the motor 19 penetrates through the screening box body 2 and extends to the inside and is fixed with a cam 20. The cam 20 abuts against the bottom of the housing 8. Baffles 21 are fixedly connected to both the left and right sides of the bottom of the housing 8. The baffle 21 is inclined. Two limiting members 12 are rotatably connected to the front surface of the housing 8. One side of the limiting member 12 is located on the front surface of the slider 13.

[0026] It should be noted that by synchronously rotating the motors 19 on both sides to drive the cam 20 to rotate, the housing 8 can be pushed up and down, so that the broken steel on the sieve plate 10 can be quickly screened. The qualified broken steel will be discharged from the discharge hopper 23, and the unqualified broken steel will remain on the top of the sieve plate 10. After the qualified broken steel is completely discharged, open the box door 22. After rotating the limiting member 12 upward and moving it away from the surface of the slider 13, the handle can be pulled to draw the sieve plate 10 out of the housing 8, so that the unqualified broken steel on the top of the sieve plate 10 can fall off, thus facilitating the discharge of the unqualified broken steel.

[0027] The baffle 21 plays a role in shielding the cam 20 to prevent the falling object from colliding with the cam 20 at any time.

[0028] It is worth mentioning that an annular resistance increasing pad is arranged on the side of the limiting member 12 close to the housing 8. The limiting member 12 is in a water droplet shape. The annular resistance increasing pad is made of rubber. By blocking the limiting member 12 in front of the slider 13, the slider 13 is restricted, preventing the sieve plate 10 from easily sliding out of the housing 8.

[0029] Please refer to Figure 3 , the crushing mechanism includes a rotor disc 5, a rotating shaft 7 and a hammer head 6. The rotor disc 5 is rotatably connected inside the crusher housing 3 through the rotating shaft 7. There are four hammer heads 6. The four hammer heads 6 are installed equidistantly around the rotor disc 5. A plurality of counterattack plates 4 are arranged on the inner wall of the crusher housing 3.

[0030] It should be noted that a control panel is installed on the outer wall of the screening box body 2, and a driving motor is fixedly installed on the outer wall of the crusher housing 3. The driving motor is fixedly connected to the rotating shaft 7.

[0031] Among them, an opening is formed on the front surface of the screening box body 2. A box door 22 is hinged inside the opening. A discharge hopper 23 is fixedly penetrated through the front surface of the screening box body 2. A material guiding plate 11 is fixedly installed on the inner bottom wall of the screening box body 2.

[0032] The working principle of the above-mentioned embodiment is as follows: During use, scrap steel enters the crusher housing 3 from the feed inlet. The rotating rotor disc 5 drives the hammers 6 to rotate to hammer the scrap steel, and the scrap steel can be torn and rolled into crushed steel. The crushed steel is discharged from the discharge port 9 and enters the housing 8 and falls on the top of the sieve plate 10. By driving the cam 20 to rotate with the motor 19, the housing 8 can be pushed to move up and down, and the movable block 16 can slide on the sliding rod 17. With the elasticity of the spring 18 itself, the housing 8 can drive the sieve plate 10 to vibrate, so that the crushed steel on the sieve plate 10 can be quickly screened. The qualified crushed steel will be discharged from the discharge hopper 23, and the unqualified crushed steel will remain on the top of the sieve plate 10. After the qualified crushed steel is completely discharged, open the box door 22. After rotating the limiting member 12 upward and moving it away from the surface of the slider 13, the handle can be pulled to draw the sieve plate 10 out of the housing 8, so that the unqualified crushed steel on the top of the sieve plate 10 can fall, thus facilitating the discharge of the unqualified crushed steel.
