[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a scrap iron screw conveyor recycling device. (Refer to...) Figure 1-4 A scrap iron screw conveyor recycling device includes a screw conveyor 1 and a feed hopper 2 connected to the top of the screw conveyor 1. The feed hopper 2 is equipped with a screen 3, and two crushing rollers 4 located above the screen 3 are rotatably connected inside the feed hopper 2.

[0034] The drive assembly 5 is located on one side of the feed hopper 2. The drive assembly 5 is connected to the crushing roller 4 and is used to drive the rotation of the crushing roller 4.

[0035] The drive assembly 6, which is disposed between the crushing roller 4 and the screen 3, is used to drive the movement of the screen 3;

[0036] The elastic component 7 is disposed between the screen 3 and the feed hopper 2 to support the elastic movement of the screen 3.

[0037] In this embodiment, when conveying scrap iron, the scrap iron is first fed into the feed hopper 2. Then, under the movement of the drive component 5, the crushing roller 4 is driven to rotate, causing the crushing roller 4 to crush the scrap iron. After crushing, the scrap iron falls onto the screen 3. At the same time, with the cooperation of the push component 6 and the elastic component 7, the screen 3 is driven to vibrate, so that the crushed scrap iron can be screened through the screen 3. Larger scrap iron can fall through the screen 3 into the screw conveyor 1 for conveying, while larger scrap iron remains on the screen 3. An operation port is opened on one side of the feed hopper 2. Larger scrap iron on the screen 3 can be taken out through the operation port, which is convenient for the scrap iron to be crushed again. When it is not necessary to take it out, the operation port is closed by the cover door, thereby avoiding the blockage of larger scrap iron during the conveying process, facilitating the conveying of scrap iron and improving the conveying efficiency of scrap iron.

[0038] In a further embodiment, such as Figure 2As shown, the drive assembly 5 includes a first gear 51 that is fixedly disposed at one end of each of the two crushing rollers 4 and meshes with each other. A motor base 52 is fixed on one side of the feed hopper 2, and a first drive motor 53 that is fixed to the first gear 51 is fixed on the top of the motor base 52.

[0039] In this embodiment, the first drive motor 53 drives the meshing rotation of two first gears 51, which in turn drives the rotation of two crushing rollers 4. Thus, when scrap iron is transported into the feed hopper 2, it can be crushed by the crushing rollers 4, reducing the volume of the scrap iron and facilitating its transport.

[0040] In a further embodiment, such as Figure 2 As shown, the pushing component 6 includes a collision plate 61 fixedly mounted on the top of the screen 3, and a cam 62 that abuts against the collision plate 61 is sleeved on the outer wall of the crushing roller 4. The elastic component 7 includes a first slider 71 fixedly mounted on both sides of the screen 3. A first groove 72 for sliding of the first slider 71 is opened on both sides of the inner wall of the feed hopper 2. The first groove 72 is fixedly connected to the first slider 71 by a spring 73.

[0041] In this embodiment, when the crushing roller 4 rotates, it drives the cam 62 to rotate. The rotation of the cam 62 drives the collision plate 61 to move, and the collision plate 61 drives the screen 3 to move. The screen 3 then drives the first slider 71 to stretch the spring 73. Thus, under the reciprocating rotation of the cam 62 and the elastic force of the spring 73, the screen 3 can be driven to vibrate continuously. The screen 3 can screen the scrap iron during vibration, and the larger scrap iron can be taken out through the operating port after screening.

[0042] In a further embodiment, such as Figure 1 As shown, the bottom end of the screw conveyor 1 is provided with a base 8. A first support plate 9 that rotates with the screw conveyor 1 is fixed on one side of the top end of the base 8. A second support plate 10 that abuts against the screw conveyor 1 is fixed on the other side of the top end of the base 8. A bracket 11 is fixed in the middle of the top end of the base 8. A rotating shaft 12 is rotatably connected to the bracket 11. A rotating assembly 13 that drives the rotating shaft 12 is provided on one side of the bracket 11. A rotating plate 14 is sleeved on the outer wall of the rotating shaft 12. A U-shaped frame 15 is fixed at the bottom end of the screw conveyor 1. The U-shaped frame 15 is connected to the rotating plate 14 through a connecting assembly 16.

[0043] In this embodiment, a discharge port is provided at the left end of the screw conveyor 1. When scrap iron needs to be conveyed to different heights for recycling, the rotating component 13 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the rotating plate 14 to rotate. The rotating plate 14 drives the U-shaped frame 15 to move up and down through the connecting component 16. The U-shaped frame 15 drives the left end of the screw conveyor 1 to move up and down, thereby adjusting the height of the discharge port of the screw conveyor 1, which facilitates the discharge of scrap iron by the screw conveyor 1 and improves the discharge efficiency of scrap iron.

[0044] In a further embodiment, such as Figure 3 As shown, the rotating assembly 13 includes a second drive motor 131 fixedly mounted on one side of the bracket 11. The output shaft of the second drive motor 131 is fixed with a second gear 132. One end of the rotating shaft 12 is fixed with a third gear 133 that meshes with the second gear 132. The connecting assembly 16 includes a second slider 161 hinged to one end of the rotating plate 14. The bottom end of the U-shaped frame 15 is provided with a second slide groove 162 for the second slider 161 to slide.

[0045] In this embodiment, when it is necessary to adjust the discharge port height of the screw conveyor 1, the second drive motor 131 drives the second gear 132 to rotate, the second gear 132 drives the third gear 133 to rotate, and the third gear 133 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the rotating plate 14 to rotate upward. During the rotation of the rotating plate 14, the second slider 161 slides in the second slide groove 162. Under the action of the rotation of the rotating plate 14, the U-shaped frame 15 moves upward, thereby driving the left end discharge port of the screw conveyor 1 to move upward, adjusting the discharge port height of the screw conveyor 1, thereby facilitating the discharge of scrap iron by the screw conveyor 1 and improving the discharge efficiency of scrap iron.

[0046] The implementation principle of the scrap iron screw conveyor recycling device in this application embodiment is as follows: When conveying scrap iron, it is first fed into the feed hopper 2. Simultaneously, under the movement of the first drive motor 53, two first gears 51 are driven to mesh and rotate. The two first gears 51 drive two crushing rollers 4 to rotate. Thus, when the scrap iron is conveyed into the feed hopper 2, it can be crushed by the crushing rollers 4, reducing the volume of the scrap iron and facilitating its conveying. At the same time, the rotation of the crushing rollers 4 drives the rotation of the cam 62. The rotation of the cam 62 drives the movement of the collision plate 61, which in turn drives the movement of the screen 3. The screen 3 then drives the first slider 71 to stretch the spring 73. Thus, under the reciprocating rotation of the cam 62 and the elastic force of the spring 73, the screen 3 can be driven to vibrate continuously. The screen 3 can screen scrap iron during vibration, avoiding blockages caused by larger scrap iron during transport, facilitating scrap iron transport and improving transport efficiency. During discharge, the second drive motor 131 drives the second gear 132 to rotate, which in turn drives the third gear 133 to rotate, which in turn drives the rotating shaft 12 to rotate. The rotating shaft 12 then drives the rotating plate 14 to rotate upward. During the rotation of the rotating plate 14, the second slider 161 slides within the second chute 162. Under the action of the rotating plate 14, the U-shaped frame 15 moves upward, thereby driving the left end discharge port of the screw conveyor 1 to move upward. Adjusting the discharge port height of the screw conveyor 1 facilitates the discharge of scrap iron and improves the scrap iron discharge efficiency.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
