[0026] Referring to Figures 1-5, a partition plate 16 is fixedly connected to the inner upper wall of the sorting box 1. A material guiding pipe 17 is installed in the middle of the lower surface of the partition plate 16. An electromagnetic valve 18 is installed on the outer surface of the lower end of the material guiding pipe 17. A sorting mechanism 3 is installed on the inner middle wall of the sorting box 1. Specifically, the crushed material can fall onto the upper surface of the partition plate 16, and then the electromagnetic valve 18 can be opened to make the crushed material fall from the material guiding pipe 17 onto the sorting mechanism 3.

[0027] Refer to Figures 1-5 , the sorting mechanism 3 includes two lower U-shaped troughs 31. The lower U-shaped troughs 31 are fixedly connected to the inner middle wall of the sorting box 1. A sliding plate 32 is slidably connected to the inner surface of the lower U-shaped trough 31. A cross plate 33 is fixedly connected to the right side surface of the left sliding plate 32. A damper 34 and a spring 35 are arranged on the upper surface of the cross plate 33. A filter screen 36 is arranged on the upper surfaces of the damper 34 and the spring 35. A vibration motor 39 is installed in the middle of the lower surface of the filter screen 36. A vertical plate 37 is fixedly connected to the upper surface of the right sliding plate 32 at the position where the right sliding plate 32 extends out of the lower U-shaped trough 31. An upper U-shaped trough 38 is fixedly connected to the upper surface of the vertical plate 37. The inner surface of the upper U-shaped trough 38 is clamped with the right side surface of the filter screen 36. Specifically, starting the vibration motor 39 can vibrate the filter screen 36, and the damper 34 and the spring 35 can limit the vibration amplitude of the filter screen 36. The upper U-shaped trough 38 can limit the vibration range of the right end of the filter screen 36 to prevent the vibration range from being too large, so that the smaller neodymium iron boron magnetic material particles that meet the standards can pass through the filter screen 36 and fall onto the inner bottom surface of the sorting box 1, while the neodymium iron boron magnetic material particles that do not meet the crushing standards will be left on the upper surface of the filter screen 36 for subsequent recycling and secondary crushing. Through the cooperation of the above structures, the vibration sorting of the neodymium iron boron magnetic material crushing particles that meet the standards can be carried out to improve the sorting efficiency.

[0028] Refer to Figures 1-5 , a discharge pipe 14 is communicated with the inner cavity at the bottom end of the sorting box 1. A valve 15 is arranged on the outer surface of the lower end of the discharge pipe 14. Specifically, opening the valve 15 can make the smaller neodymium iron boron magnetic material particles that meet the standards discharge from the discharge pipe 14.

[0029] Refer to Figures 1-5 , a sealing plate 11 is arranged on the front side surface of the sorting box 1. A handle 12 is fixedly connected to the outer surface of the sealing plate 11. One side surface of the sealing plate 11 away from the handle 12 is fixedly connected to the sliding plate 32. Specifically, when it is necessary to take out the larger-particle neodymium iron boron magnetic material on the upper surface of the filter screen 36, the handle 12 can be held to pull the sealing plate 11 outwards. At this time, the sealing plate 11 will drive the sliding plate 32 to slide on the inner surface of the lower U-shaped trough 31, so as to take out the filter screen 36 and the larger-particle neodymium iron boron magnetic material on its upper surface from the inside of the sorting box 1, which is convenient for subsequent recycling and secondary crushing.

[0030] Refer toFigures 1-5 , the input ends of the solenoid valve 18, the motor 22 and the vibration motor 39 are electrically connected to an external power supply; specifically, the external power supply can provide electrical energy for the start of the solenoid valve 18, the motor 22 and the vibration motor 39.

[0031] The implementation principle of an embodiment of the neodymium iron boron magnetic crushing and sorting device of the present application is as follows:

[0032] When using this device, first connect to an external power supply, and then the neodymium iron boron magnetic material to be crushed can be poured into the crushing box 2 from the feed port 21. At this time, starting the motor 22 can make the crushing roller 23 drive the crushing blade 24 to rotate, so as to crush the neodymium iron boron magnetic material. The crushed material can fall onto the upper surface of the partition plate 16. Then, the solenoid valve 18 can be opened to make the crushed material fall from the guide pipe 17 onto the upper surface of the filter screen 36; then start the vibration motor 39 to vibrate the filter screen 36, and the damper 34 and the spring 35 can limit the vibration amplitude of the filter screen 36, and the upper U-shaped groove body 38 can limit the vibration range of the right end of the filter screen 36 to prevent the vibration range from being too large, so that the smaller neodymium iron boron magnetic material particles that meet the standards can pass through the filter screen 36 and fall to the inner bottom surface of the sorting box 1, while the neodymium iron boron magnetic material particles that do not meet the crushing standards will be left on the upper surface of the filter screen 36 for subsequent recycling and secondary crushing; through the cooperation of the above structures, the vibration sorting of the neodymium iron boron magnetic material crushing particles that meet the standards can be carried out to improve the sorting efficiency.

[0033] On the other hand, when it is necessary to take out the larger particle neodymium iron boron magnetic material on the upper surface of the filter screen 36, the handle 12 can be held and the sealing plate 11 can be pulled outwards. At this time, the sealing plate 11 will drive the sliding plate 32 to slide on the inner surface of the lower U-shaped groove body 31, so as to take out the filter screen 36 and the larger particle neodymium iron boron magnetic material on its upper surface from the inside of the sorting box 1, which is convenient for subsequent recycling and secondary crushing.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
