Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 As shown, this utility model is a metal waste crushing and shearing device, including a crushing box 1 and a first motor 2 fixed at the top of one end of the crushing box 1.

[0025] It also includes: the output end of the first motor 2 is connected to the first protective plate 3, and the other end of the first protective plate 3 is connected to the driving wheel 4. The outer surfaces of the driving wheel 4 and the driven wheel 6 are provided with small teeth, and the driving wheel 4 and the driven wheel 6 are meshed with the internal tooth belt 5 through the teeth. The outer surface of the driving wheel 4 is fitted with the internal tooth belt 5, and the inner side of the other end of the internal tooth belt 5 is connected to the driven wheel 6. A second protective plate 7 is distributed on one side of the first protective plate 3. The second protective plate 7 and the first protective plate 3 are rotatably connected to the crushing box 1 through the bearing seat. A cylinder 8 is fixed at the top of the front end of the crushing box 1, and the output end of the cylinder 8 is connected to the extrusion plate 9. A protrusion 10 is fixed on the other end surface of the extrusion plate 9.

[0026] During operation, the first motor 2 first operates, causing the first protective plate 3 connected to its output end to rotate. Then, the first protective plate 3 rotates along one side of the top of the crushing box 1 via a bearing seat, forming an L-shape to close the opening at the top of the crushing box 1. Simultaneously, the rotation of the first protective plate 3 drives the drive wheel 4 to rotate, which in turn causes the internal toothed belt 5, meshed with its outer surface, to rotate. The movement of the internal toothed belt 5 causes the driven wheel 6, meshed with its inner side at the other end, to rotate the second protective plate 7. The second protective plate 7 moves towards the first protective plate 3, and one end of the second protective plate 7 contacts one end of the first protective plate 3, closing the opening at the top of the crushing box 1. The two protective plates... The contact between the guard plates forms a platform on which the metal scrap to be crushed is placed. Then, the cylinder 8 pushes the extrusion plate 9, causing the two extrusion plates 9 to move towards each other. The opposing extrusion plates 9 drive the protrusion 10 to contact the metal scrap and extrude it, causing the metal scrap to deform and making it easier to crush in the future. After extrusion, the first motor 2 drives the first guard plate 3 to reverse, and then the first guard plate 3 drives the drive wheel 4 to rotate, causing the internal toothed belt 5 to drive the driven wheel 6 to flip, thereby resetting the second guard plate 7. After the two guard plates are reset, the metal scrap placed on the surface of the guard plates will fall into the inside of the crushing box 1, making it easier to crush the metal scrap in the future.

[0027] A second motor 11 is fixedly installed on the side wall of the crushing box 1, and the output end of the second motor 11 is connected to a first crushing roller 12. Multiple teeth are equally spaced on the outer surfaces of the first crushing roller 12 and the second crushing roller 15, and the teeth on the two surfaces are meshed together. A drive gear 13 is fixedly connected to the other end of the first crushing roller 12, and a driven gear 14 is connected to one side of the drive gear 13. The driven gear 14 is meshed with the drive gear 13 through the teeth, and the driven gear 14 is fixedly connected to the second crushing roller 15. The second crushing roller 15 is distributed on one side of the first crushing roller 12.

[0028] During operation, the second motor 11 operates, causing the first crushing roller 12 connected to its output end to rotate. Then, the rotation of the first crushing roller 12 drives the drive gear 13, which is fixedly connected to its other end, to rotate as well. Since the drive gear 13 and the driven gear 14 are connected by tooth meshing, the rotation of the drive gear 13 can cause the driven gear 14 to rotate accordingly. This facilitates the subsequent rotation of the second crushing roller 15 by the rotation of the driven gear 14. Furthermore, under the action of the drive gear 13, the driven gear 14 will drive the second crushing roller 15 to move in opposite directions to the first crushing roller 12, thereby effectively achieving the crushing and processing of metal waste.

[0029] A flow divider seat 16 is fixedly installed at the bottom of the inner cavity of the crushing box 1, and a discharge port 17 is opened on one side of the bottom of the crushing box 1.

[0030] During operation, the crushed metal scrap falls onto the diversion seat 16. Due to the symmetrical inclined surface at the top of the diversion seat 16, the metal scrap falling onto the diversion seat 16 moves along the inclined surface and is discharged through the discharge port 17.

[0031] The bottom of the first protective plate 3 is fixed with a card plate 18, and the bottom side of the second protective plate 7 is provided with a card slot 19. The size of the card slot 19 is adapted to the size of the card plate 18, and the card plates 18 are symmetrically distributed along the vertical center line of the first protective plate 3.

[0032] During operation, when the first protective plate 3 and the second protective plate 7 move toward each other, the first protective plate 3 will drive the locking plate 18 to engage with the locking groove 19 opened on one side of the bottom of the second protective plate 7, thereby improving the stability of the engagement between the two.

[0033] The first protective plate 3 is rotatably connected to the crushing box 1 through a bearing seat, and both the first protective plate 3 and the second protective plate 7 are "L" shaped;

[0034] During operation, the first protective plate 3 rotates along the crushing box 1 under the action of the first motor 2. Since both the first protective plate 3 and the second protective plate 7 are "L" shaped, the entire crushing box 1 can be sealed when the two protective plates come into contact with each other.

[0035] The protrusions 10 are evenly distributed along the surface of the extrusion plate 9, and the extrusion plate 9 is symmetrically distributed along the vertical center line of the crushing box 1;

[0036] During operation, since the protrusions 10 are evenly distributed on one end surface of the extrusion plate 9, when the cylinder 8 works to push the extrusion plate 9, the extrusion plate 9 will push the protrusions 10, which makes it convenient to use the protrusions 10 to extrude the metal scrap and facilitate better crushing of the metal scrap in the future.

[0037] Working principle: The first motor 2 rotates the first protective plate 3, which then rotates along one side of the top of the crushing box 1 via the bearing seat, forming an L-shape. Simultaneously, the rotation of the first protective plate 3 drives the drive wheel 4, causing the internal toothed belt 5 to rotate as well. The movement of the internal toothed belt 5 causes the driven wheel 6 to rotate the second protective plate 7, bringing one end of the second protective plate 7 into contact with one end of the first protective plate 3, thus sealing the top opening of the crushing box 1. The contact between the two protective plates forms a platform on which the metal scrap to be crushed is placed. Then, the cylinder 8 pushes the extrusion plate 9, which, through its opposing movement, causes the protrusion 10 to contact the metal scrap. The metal scrap is compressed and deformed. After compression, the first motor 2 drives the first protective plate 3 to reverse. Then, the first protective plate 3 drives the drive wheel 4 to rotate, causing the internal gear belt 5 to drive the driven wheel 6 to flip, thereby resetting the second protective plate 7. After the two protective plates are reset, the metal scrap placed on the surface of the protective plates will fall into the inside of the crushing box 1. At this time, the second motor 11 works to make the first crushing roller 12 rotate. Then, the first crushing roller 12 drives the drive gear 13 to move. The rotation of the drive gear 13 can drive the driven gear 14 to rotate the second crushing roller 15. The second crushing roller 15 and the first crushing roller 12 move in opposite directions, thereby effectively crushing the metal scrap.

[0038] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
