[0034] Reference Figure 1-7 The utility model provides an embodiment of a waste crusher for recycling waste magnetic materials, comprising a shell 1, a collection box 6 and two rotating shafts 27. The top of one side of the inner wall of the collection box 6 is rotatably connected to an electromagnet 10. The electromagnet 10 is rotated to adjust its slope to increase the contact time between the magnetic waste and the electromagnet 10, thereby improving the effect of the electromagnet 10 in collecting the magnetic waste.

Both the slide groove 17 and the slider 18 are cross-shaped.

[0035] A filter plate 2 14 is fixedly connected to the collection box 6. A plurality of evenly distributed through holes 3 13 are provided on the top of the filter plate 2 14.

The position of the filter plate 1 7 can be rotated to screen non-magnetic materials and impurities of different coarsenesses. When the non-magnetic materials and impurities inside the magnetic waste enter the collection box 6 through the electromagnet 10, the angle between the through hole 11 and the through hole 2 12 can be adjusted by rotating the filter plate 1 7. By adjusting the angle of the filter plate 1 7, it can adapt to different usage environments. When the through hole 11 corresponds to the through hole 3 13, the diameter of the through hole 11 is smaller, so finer non-magnetic materials and impurities can be screened. When the through hole 2 12 corresponds to the through hole 3 13, coarser non-magnetic materials and impurities can be screened.

[0036] The front and rear ends and the left and right sides of the inner wall of the shell 1 are rotatably connected to the fixed seat 20, the front end of the front fixed seat 20 passes through the shell 1 and is fixedly connected to the gear 5, the rear end of the shell 1 is fixedly connected to the motor 2, the driving end of the motor 2 passes through the shell 1 and is fixedly connected to the rear end of the fixed seat 20, the outer sides of the two ends of the two rotating shafts 27 are arranged inside the multiple fixed seats 20, and the outer sides of the two rotating shafts 27 are fixedly connected to the rolling rollers 22.

When the rotating shaft 27 needs to be installed, it can be placed inside the fixing seat 20, and then the pull rod 23 is loosened to allow the spring 24 to rebound and push the fixing block 29 into the fixing groove 21, thereby fixing the rotating shaft 27 to the inside of the fixing seat 20.

[0038] A fixing groove 21 is provided on both sides of the rotating shaft 27. The ends of the multiple fixing blocks 29 away from the pull rod 23 are slidably connected inside the multiple fixing grooves 21.

[0040] A top cover 4 is provided at the top of the shell 1, and plug-ins 19 are fixedly connected on both sides of the bottom end of the top cover 4. Slots 9 are provided on both sides of the top of the shell 1, and the two plug-ins 19 are slidably connected to the inside of the slots 9. Bolts 3 are threadedly connected on both sides of the bottom ends of the two plug-ins 19, and the other ends of the two bolts 3 pass through both sides of the top of the shell 1. When it is necessary to clean the impurities and dust attached to the inside of the shell 1, the bolts 3 can be removed and the top cover 4 can be lifted upward to make the plug-ins 19 withdraw from the inside of the slots 9, and then the upper shell can be removed from the top of the shell 1, and the cover at the front end of the shell 1 can be opened so that the staff can clean the shell 1.

[0041] A discharge port 15 is provided at one side of the bottom end of the housing 1 , and a plug 8 is slidably connected to the inside of the discharge port 15 .

[0042] The diameter of through hole 2 12 is the same as that of through hole 1 11 , and the diameter of through hole 3 13 is smaller than that of through hole 1 11 and through hole 2 12 . When through hole 1 11 corresponds to through hole 3 13 , the diameter of through hole 1 11 is smaller, so that finer non-magnetic materials and impurities can be screened. When through hole 2 12 corresponds to through hole 3 13 , coarser non-magnetic materials and impurities can be screened.

[0043] Working principle: When the magnetic material needs to be crushed, it can be poured into the shell 1 through the feed port at the top of the upper cover 4, and then the motor 2 drives the fixed seat 20 to drive the rotating shaft 27 to rotate, and the two gears 5 can drive the two rolling rollers 22 to rotate relative to each other, so as to crush the magnetic material inside the shell 1. At the same time, the crushed magnetic material can fall between the two rolling rollers 22 and fall to the top of the electromagnet 10. The magnetic force generated by the electromagnet 10 can adsorb the magnetic material. At the same time, the non-magnetic material and impurities inside the magnetic material can fall into the collection box 6 under the guidance of the electromagnet 10. And it can be screened with impurities through the filter plate 1 7 and the filter plate 2 14, so that it is convenient for the staff to further process the non-magnetic materials and impurities; the electric push rod 16 can push the slider 18 to slide inside the slide 17, and the movement of the slider 18 can push the electromagnet 10 to rotate, thereby adjusting the angle of the electromagnet 10, increasing the contact time between the magnetic material and the electromagnet 10, and thus increasing the collection effect of the electromagnet 10. When the rolling roller 22 is worn out after long-term use and needs to be replaced, the bolts 3 on the top of both sides of the shell 1 can be removed, and then the upper cover 4 can be lifted to remove it from the top of the shell 1 The two ends of the rolling shaft 27 can be removed and the pull rods 23 on both sides of the fixing seat 20 can be pulled to both sides to drive the fixing blocks 29 to exit the fixing groove 21, and the two rolling rollers 22 can be lifted up to take out the rotating shaft 27 from the fixing seat 20 and replace it. When the rolling roller 22 needs to be installed, the two ends of the rotating shaft 27 can be put into the fixing seat 20, so that the positioning blocks 28 can be extended into the positioning groove 25 to preliminarily fix the rolling roller 22. The pull rod 23 can then be loosened to allow the spring 24 to rebound and push the fixing block 29 into the fixing groove 21 to fix the rolling roller 22. When screening magnetic materials and impurity particles, the filter plate 1 7 can be rotated to adjust the positions of the through hole 1 1 and the through hole 2 12 to filter non-magnetic materials and impurity particles of different coarseness and fineness. When the through hole 11 corresponds to the through hole 3 13, the diameter of the through hole 11 is smaller, so the finer non-magnetic materials and impurity particles can be screened. At the same time, when the through hole 2 12 corresponds to the through hole 3 13, the diameter of the through hole 2 12 is larger, so the coarser non-magnetic materials and impurity particles can be screened. When it is necessary to clean the impurities inside the collection box 6, the plug 8 can be pulled out so that the impurities inside the collection box 6 can be poured out through the discharge port 15.

[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.
