The detachable setting of the screen frame 21 and the frame cover 22 ensures that the magnetic material adhered to the magnetic waste can be placed in the interior of the screen frame 21, and the magnetic material is not easy to fall out during the screening operation. A screening hole 23 is opened at the bottom end of the screen frame 21, and the diameter of the screening hole 23 is smaller than the length of the magnetic material in any direction. The setting of the diameter of the screening hole 23 ensures that the magnetic material itself cannot leave the screening hole 23.

[0035] Reference Figure 2 、 Figure 3 and Figure 7 The inner wall of the body 1 is fixedly connected with a cylinder 24, and the output shaft of the cylinder 24 is fixedly connected with a slide plate 25. The sliding direction of the slide plate 25 is up and down. The upper surface of the slide plate 25 is fixedly connected with an electromagnet 26. The electromagnet 26 is electrically connected to the power supply of the device through a wire, and when the device is powered on, the electromagnet 26 has magnetism. When the device is not powered on, the electromagnet 26 has no magnetism. This technology is a prior art and can be implemented by technicians in this field, so it will not be described in detail in this case. The magnetic force of the electromagnet 26 after power is applied is greater than the magnetic force of the magnetic material screened by the device.

[0036] Reference Figure 4 - Figure 6, a shaking assembly 27 is provided inside the body 1, and the shaking assembly 27 includes a mounting chamber 271. The inner wall of the body 1 above the mounting chamber 271 is provided with a hole with a top diameter larger than the sieve hole 23 and a bottom diameter consistent with the sieve hole 23. The mounting chamber 271 is provided on the inner wall of the body 1 at the rear side of the slide 25. The inner wall of the mounting chamber 271 is fixedly connected with a mounting block 272, and the mounting block 272 has and only has a front end connected to the inner wall of the mounting chamber 271. The top of the mounting block 272 is fixedly connected with a motor 273, and the output shaft of the motor 273 is fixedly connected with a rotating rod 274. The outer wall of the rotating rod 274 is fixedly connected with a rotating bar 275. The middle part of the front end of the mounting block 272 is provided with a groove with a length twice the length of the rotating bar 275. The setting of the groove ensures that the rotating bar 275 will not contact the mounting block 272 when rotating.

[0037] Reference Figure 4 - Figure 6 The rear end of the rotating bar 275 is fixedly connected to a control rod 276, the length of the control rod 276 is longer than the front and rear length of the motor 273, and the inner wall of the body 1 at the rear end of the mounting bin 271 is provided with a sliding groove 277, and the inner wall of the sliding groove 277 is slidably connected to a sliding rod 278, and the sliding rod 278 is at the rear end of the motor 273. The inner wall of the sliding rod 278 is provided with a moving groove 279, and both ends of the moving groove 279 are set to rounded corners. The rear end of the control rod 276 is set inside the moving groove 279, and the width of the moving groove 279 matches the diameter of the control rod 276. The top of the sliding rod 278 is fixedly connected to a moving block 2710, and the inner wall of the moving block 2710 is provided with a moving hole 2711. The shape of the moving hole 2711 is a straight notch shape, and a driving rod 2712 is provided inside the moving hole 2711. The shape of the driving rod 2712 is cylindrical, and the front end of the driving rod 2712 is fixedly connected to the left side of the rear end of the screen frame 21.

[0038] Reference Figure 3 - Figure 5 The outer wall of the eccentric wheel 284 is fixedly connected to the front end of the rotating rod 274, and the eccentric wheel 284 is arranged at the rear end of the lower side of the inclined plate 282.

[0039] Working principle: When in use, the staff first opens the door of the equipment, then opens the frame cover 22, and places the magnetic material with magnetic waste attached to it inside the screen frame 21, and then closes the frame cover 22. After closing, the staff first starts the cylinder 24, so that the output shaft of the cylinder 24 drives the slide 25 to move upward until the top of the slide 25 contacts the inner wall of the body 1. At this time, the staff starts the equipment power supply of the control electromagnet 26, so that the electromagnet 26 has magnetism after being energized.

[0040] When the electromagnet 26 has magnetism, the staff starts the motor 273, so that the motor 273 drives the rotating rod 274 to rotate, so that the rotating rod 274 drives the rotating bar 275 to rotate, so that the rotating bar 275 drives the control rod 276 to rotate around the rotating rod 274 during the rotation process.

[0041] Since the rotation path of the control rod 276 is to rotate around the rotating rod 274, the height of the control rod 276 changes during the rotation process. Therefore, the control rod 276 can drive the slide rod 278 to move up and down through the moving groove 279 during the rotation process, so that the slide rod 278 drives the moving block 2710 to move up and down, thereby causing the driving rod 2712 to move up and down.

[0042] Since the screen frame 21 is rotatably connected to the inner wall of the body 1, and the driving rod 2712 is fixedly connected to the screen frame 21, the path of the driving rod 2712 moving up and down is an arc path with the center position of the rotating shaft connecting the screen frame 21 and the body 1 as the center of the circle. Since a moving hole 2711 is opened inside the driving rod 2712, it can ensure that the up and down movement of the driving rod 2712 is not interfered with.

[0043] During the left and right shaking of the screen frame 21, the magnetic material inside the screen frame 21 and the magnetic waste attached to its surface move left and right, so the magnetic material and the magnetic waste can both contact the surface of the electromagnet 26. Since the waste attached to the magnetic material is relatively light, it is not easy to move again after being adsorbed on the surface of the electromagnet 26 during the shaking process, so the surface of the electromagnet 26 can more easily adsorb the magnetic waste.

[0044] When the adsorption is completed, the staff starts the cylinder 24 so that the output shaft of the cylinder 24 drives the slide 25 to move downward, thereby moving the electromagnet 26 downward, so that the electromagnet 26 and the magnetic waste adsorbed on its surface are moved to the inside of the collection bin 281.

[0045] Since the inner wall of the hole opened in the inner wall of the inclined plate 282 fits exactly with the surface of the electromagnet 26, when the electromagnet 26 moves downward, the magnetic material attached to the lower surface of the electromagnet 26 can be scraped away by the upper surface of the inclined plate 282 and remain inside the collection bin 281.

[0046] At this time, the staff first turns off the motor 273. After taking out the magnetic material, the staff closes the frame cover 22 and then turns off the power corresponding to the electromagnet 26. At the same time, the power of the motor 273 is started, so that the electromagnet 26 loses its magnetism, so that the magnetic waste adsorbed by the electromagnet 26 only has the attraction between the magnetic waste and the iron core inside the electromagnet 26.

[0047] At this time, since the motor 273 drives the rotating rod 274 to rotate, the rotating rod 274 drives the eccentric wheel 284 to rotate. Therefore, when the eccentric wheel 284 moves to the raised position upward, it can drive the inclined plate 282 to move upward. When the moving protrusion is downward, the inclined plate 282 can move downward under the action of gravity. Therefore, at this time, the inclined plate 282 can make reciprocating motion up and down driven by the eccentric wheel 284, thereby generating vibration.

[0048] Since the magnetic waste is less affected by the magnetic force at this time, when vibration occurs, the magnetic waste can move toward the front end and eventually enter the interior of drawer 283. At this time, the staff only needs to open drawer 283 to take out the magnetic waste inside drawer 283.

[0049] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
