[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1 The utility model provides an embodiment: a crushing device for metal processing, including a base 1, with support plates 2 slidably connected to both ends of the top of the base 1, a box 3 fixedly connected to the upper part of the two support plates 2, and metal silicon is crushed in the middle of the box 3. A crushing assembly is fixedly connected to the top of the box 3, and the crushing assembly includes two crushing rollers 5, both of which are rotatably connected to the middle of the box 3, and a gear 6 is fixedly connected to the outside of the crushing roller 5. The two gears 6 are meshed with each other, and a motor 4 is fixedly connected to the outside of the box 3, and one of the crushing rollers 5 is fixedly connected to the output end of the motor 4. After the metal silicon powder to be crushed is put into the box 3 from the top, the motor 4 is powered, and then the two crushing rollers 5 are rotated under the action of the gear 6, so as to crush the silicon powder.

[0036] Reference Figure 4 A sieve plate 15 is fixedly connected to the inside of the box body 3, and the crushed silicon powder can be screened through the sieve plate 15, and the smaller silicon powder directly falls down to the top of the base 1, and the larger silicon powder remains above the sieve plate 15. A discharge port 14 is opened in the middle of the box body 3, and the silicon powder located above the sieve plate 15 can be discharged from the discharge port 14.

[0037] Reference Figure 2-Figure 5 The upper part of the support plate 2 is also fixedly connected to the mounting plate 7, and the middle part of the mounting plate 7 is provided with a slide groove 1 8, a slide groove 2 9 and a limit groove 10. The outer side of the mounting plate 7 is fixedly connected to the lifting assembly, and a threaded block 13 is installed on the outer side of the lifting assembly. The lifting assembly includes a motor 2 11, which is fixedly connected to the outer side of the mounting plate 7. The top output end of the motor 2 11 is fixedly connected to a threaded rod 12, and the threaded block 13 is threadedly connected to the outer periphery of the threaded rod 12. The motor 2 11 can drive the threaded rod 12 to rotate, and then the threaded block 13 can be moved up and down. The threaded block 13 slides in the middle of the limit groove 10, and the threaded block 13 can be restricted when the threaded block 13 moves.

[0038] Reference Figure 5-Figure 6The outer side of the threaded block 13 is rotatably connected with a slider 18, and a tray 16 is slidably connected between the two mounting plates 7. The larger silicon powder discharged from the discharge port 14 will accumulate in the middle of the tray 16, and then driven by the lifting component, it will reach the top of the box 3 again, and pour the silicon powder to the upper part of the box 3 for crushing again. The bottom of the tray 16 is fixedly connected with a shell 17, and the slider 18 is slidably connected to the middle of the shell 17. Through the mutual cooperation of the shell 17 and the slider 18, the relative position of the tray 16 and the threaded block 13 can be changed, so that the tray 16 can be turned over while ensuring that the tray 16 can be lifted and lowered normally.

[0039] Reference Figure 5-Figure 6 , a plurality of limit rods 20 are fixedly connected to the outside of the tray 16, and the limit rods 20 are slidably connected inside the slide groove 1 8 and the slide groove 2 9. When the tray 16 moves upward, the limit rod 20 of the tray 16 near the box body 3 will first contact the top of the slide groove 1 8, and then the tray 16 continues to move, which will make the limit rod 20 on one side of the tray 16 contact the top of the slide groove 2 9. At this time, the tray 16 will tilt so that the silicon powder above the tray 16 can enter the box body 3. A notch 19 is opened on the side of the threaded block 13 close to the box body 3, and the slider 18 is rotatably connected above the notch 19. When the angle of the tray 16 changes, the slider 18 will slide in the middle of the shell 17 to ensure the normal lifting and lowering, and the slider 18 will flip along with the flipping of the tray 16. At this time, the angle of the slider 18 can be limited by the notch 19 to ensure the normal tilting.

[0040] Reference Figure 2-Figure 4 and Figure 7 A spring rod 21 is fixedly connected to the outside of the box body 3, and a baffle 22 is fixedly connected to the top of the spring rod 21. The baffle 22 is located below the discharge port 14, and the top of the baffle 22 contacts the bottom of the tray 16. When the tray 16 moves upward, the spring rod 21 will push the baffle 22 upward to block the discharge port 14 to prevent silicon powder from falling from the discharge port 14. Conversely, when the tray 16 descends, the spring rod 21 will shrink and reopen the discharge port 14 so that the silicon powder above the sieve plate 15 can enter the upper part of the tray 16. A motor three 23 is fixedly connected to the outside of the base 1, and a turntable 24 is fixedly connected to the output end of the motor three 23. A fixed rod 25 is fixedly connected to the top of the turntable 24. A rod sleeve 26 is fixedly connected to the outside of the support plate 2, and the rod sleeve 26 is sleeved on the outer periphery of the fixed rod 25. When the silicon powder is crushed, the motor 3 23 can also be driven to work, thereby driving the turntable 24 to rotate. Under the action of the fixed rod 25 and the rod sleeve 26, the support plate 2 can drive the box body 3 and the mounting plate 7 to move back and forth, thereby enhancing the screening effect of the screen plate 15 and the tray 16, thereby increasing the unloading speed.

[0041] Reference Figure 1-Figure 4A groove is provided in the middle of the base 1, and the box 3 and the tray 16 are both located above the groove. A collection bucket, a conveyor belt, etc. can be placed above the groove to convey and collect the screened silicon powder. A wedge block 27 is fixedly connected to the bottom of the support plate 2, and a matching notch is provided on the top of the base 1. The wedge block 27 cooperates with the notch to limit the position of the support plate 2 to ensure the stability of the device during operation.

[0042] Working principle: When in use, the metal silicon powder to be crushed is put in from the top of the box 3, and then the motor 1 4 and the gear 6 cooperate to drive the crushing roller 5 to rotate, so as to crush the silicon powder. The crushed silicon powder will fall down to the top of the sieve plate 15, and then the smaller silicon powder will fall down, and the larger silicon powder will stay above the sieve plate 15, and then be discharged from the discharge port 14 and collected by the tray 16. After a certain amount or a period of time has been collected, the motor 2 11 is used to drive the threaded rod 12 to rotate, so that the threaded rod 12 The block 13 moves upward, thereby driving the tray 16 to move upward to the top of the box body 3. When the limit rod 20 of the tray 16 close to the position of the box body 3 reaches above the slide groove 8, the threaded rod 12 continues to rotate. At this time, the other side of the tray 16 will tilt, and then under the action of the slider 18, the notch 19 and the shell 17, the tray 16 will tilt toward the box body 3. At this time, the silicon powder accumulated on the tray 16 will re-enter the interior of the box body 3 and can be crushed again, thereby reducing the size difference of the silicon powder discharged from the bottom of the box body 3, thereby ensuring the molding rate of the silicon powder.

[0043] Secondly, when the tray 16 moves upward, the spring rod 21 pushes the baffle 22 upward to block the discharge port 14 to prevent silicon powder from falling from the discharge port 14. When the silicon powder is crushed, the motor 3 23 can be driven to work, thereby driving the turntable 24 to rotate. Under the action of the fixing rod 25 and the rod sleeve 26, the support plate 2 can drive the box 3 and the mounting plate 7 to move back and forth, thereby enhancing the screening effect of the screen plate 15 and the tray 16, thereby increasing the unloading speed.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
