[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 This utility model discloses a crusher for recycling electromechanical products, including a crusher body 1 and a grate plate 2 inserted into the crusher body 1. It also includes: an upper plate frame 3 and a lower plate frame 4 arranged on both sides of the crusher body 1. Both sides of the crusher body 1 are provided with through holes 5 adapted to the grate plate 2. Conveying devices are fixedly arranged on the surfaces of the upper plate frame 3 and the lower plate frame 4. The conveying devices are used to disassemble and assemble the grate plate 2. A vibration device is arranged on the lower plate frame 4. The vibration device is used to vibrate and clear any blockages in the grate plate 2 on the lower plate frame 4. Fixing devices are arranged on both sides of the crusher body 1. The fixing devices are used to fix the grate plate 2 inside the crusher body 1.

[0024] Specifically, the vibration device includes two limiting frames 6, vibration springs 7, a drive assembly, and a positioning assembly. The two limiting frames 6 are respectively set on both sides of the lower plate frame 4, and one end of each limiting frame 6 is fixedly connected to the crusher body 1. The limiting frames 6 are U-shaped. The two sides of the lower plate frame 4 are respectively inserted into the interior of the two limiting frames 6. Multiple vibration springs 7 are respectively set inside the two limiting frames 6, and the two ends of the vibration springs 7 are fixedly connected to the limiting frame 6 and the lower plate frame 4 respectively. The drive assembly is fixedly set at the bottom of the limiting frame 6, and the positioning assembly is fixedly set on the surface of the lower plate frame 4. The positioning assembly is used to position the grate plate 2 on the lower plate frame 4. Multiple through slots are opened on the surface of the lower plate frame 4.

[0025] Specifically, the drive assembly includes a drive motor 8 and a cam plate 9. The drive motor 8 is mounted on the bottom side of the limit frame 6 via a mounting plate. The cam plate 9 is fixedly sleeved on the surface of the output shaft of the drive motor 8. A slot is provided at the bottom of the limit frame 6, through which the cam plate 9 can pass through the limit frame 6.

[0026] In this embodiment, after the conveying device moves the grate plate 2 onto the lower plate frame 4, if there are debris blocking the grate plate 2, the positioning component positions the grate plate 2 on the lower plate frame 4. Then, the drive motor 8 is started, and the output shaft of the drive motor 8 drives the cam plate 9 to rotate, so that the cam plate 9 passes through the slot and through the limiting frame 6. Then, the protruding part of the cam plate 9 presses the lower plate frame 4 upward, so that the lower plate frame 4 compresses the vibration spring 7 elastically. Then, the lower plate frame 4 rotates until the protruding part disengages from the lower plate frame 4, so that under the elastic force of the vibration spring 7, the lower plate frame 4 is driven to return to its original position downward, so that the lower plate frame 4 hits the inner bottom of the limiting frame 6, thereby causing the grate plate 2 on the lower plate frame 4 to vibrate, thereby vibrating and clearing the debris blocking the screen holes of the grate plate 2.

[0027] Specifically, the positioning assembly includes multiple first electric push rods 10 and positioning plates 11. The multiple first electric push rods 10 are fixedly installed at the four corners of the lower plate frame 4, and the positioning plates 11 are fixedly installed at the ends of the telescopic shafts of the first electric push rods 10. The number of positioning plates 11 is matched with the number of first electric push rods 10.

[0028] In this embodiment, after the conveying device moves the grate bar 2 onto the lower plate frame 4, it controls the telescopic shaft of the first electric push rod 10 to retract. The telescopic shaft of the first electric push rod 10 drives the positioning plate 11 to contact the surface of the grate bar 2, thereby clamping and positioning the grate bar 2 to prevent displacement during vibration.

[0029] Specifically, the conveying device includes a guide frame 12, a lead screw 13, a fixed motor 14, and a connecting assembly. One end of the guide frame 12 is fixedly mounted on the surface of the crusher body 1. One end of the lead screw 13 is connected to the inner side wall of the guide frame 12 through a bearing. The fixed motor 14 is fixedly mounted on the other end of the guide frame 12 through a flange. The output shaft of the fixed motor 14 is fixedly connected to the other end of the lead screw 13. The connecting assembly is mounted on the surface of the grate plate 2.

[0030] Specifically, the connecting components include a slider 15, an electromagnet 16, and a connecting block 17. The slider 15 is T-shaped and threaded onto the surface of the lead screw 13. The slider 15 is slidably connected to the guide frame 12. The electromagnet 16 is fixedly installed at the bottom of the slider 15, and the connecting block 17 is fixedly installed on the side of the grate plate 2.

[0031] In this implementation scheme, when the grate plate 2 needs to be replaced, firstly, the fixing device is controlled to unlock the grate plate 2. Then, the fixed motor 14 of the conveying device on the lower plate frame 4 is started, causing the output shaft of the fixed motor 14 to drive the lead screw 13 to rotate. The lead screw 13 drives the slider 15 to slide along the inner wall of the guide frame 12 through the thread, causing the slider 15 to drive the electromagnet 16 to move towards the crusher body 1. When the electromagnet 16 contacts the connecting iron block 17 on one side of the grate plate 2, the electromagnet 16 is energized to generate magnetism, thereby magnetically fixing the electromagnet 16 to the connecting iron block 17. Then, the fixed motor 14 is controlled to drive the lead screw 13 to reverse, causing the lead screw 13 to drive the slider 15 to reset. The slider 15 drives the grate plate 2 through the electromagnet 16 and the connecting iron block 17, causing the grate plate 2 to detach from the crusher body 1 through the through hole 5, thus completing the disassembly of the grate plate 2.

[0032] Specifically, the fixing device includes a second electric push rod 18, a plug block 19, and a fixing ring 20. The second electric push rod 18 is fixedly installed on the surface of the crusher body 1, the plug block 19 is fixedly installed at the end of the telescopic shaft of the second electric push rod 18, and the fixing ring 20 is fixedly installed on the side of the grate plate 2. The plug block 19 can be adapted to be inserted into the fixing ring 20.

[0033] In this embodiment, after the grate plate 2 is installed into the crusher body 1, the extension shaft of the second electric push rod 18 is extended, thereby driving the insert block 19 to fit and insert into the fixing ring 20 on the grate plate 2, thus facilitating the fixing of the grate plate 2.

[0034] The working principle and usage process of this utility model are as follows: During use, the electromechanical products to be crushed are fed into the crusher body 1 through the inlet. As the rotor inside the crusher body 1 rotates at high speed, it drives the hammers to repeatedly hammer and impact the waste electromechanical products entering the crusher body 1, causing them to break. Material smaller than the gap between the grate plates 2 is then discharged as fragments or particles that meet the requirements. When the crusher body 1 processes different electromechanical products, the selection of the screen holes in the grate plates 2 must be precisely adapted to the material characteristics. For example, crushing large metal components requires large-diameter grate plates 2 to quickly discharge blocky materials, while processing delicate components such as circuit boards requires small-diameter grate plates 2 to control the crushing particle size. When the grate plates 2 need to be replaced, first, the fixing device is controlled to unlock the grate plates 2. Then, the fixed motor 14 of the conveying device on the lower plate frame 4 is started, causing the output shaft of the fixed motor 14 to drive the lead screw 13 to rotate. The lead screw 13 drives the slider 15 to slide along the inner wall of the guide frame 12 through the thread, causing the slider 15 to drive the electromagnet 16 towards the crusher body 1. The mechanism moves until the electromagnet 16 contacts the connecting iron block 17 on one side of the grate plate 2. Then, the electromagnet 16 is energized, causing it to become magnetic, thus magnetically connecting it to the connecting iron block 17. Next, the fixed motor 14 is controlled to reverse the lead screw 13, causing the lead screw 13 to move the slider 15 back to its original position. The slider 15, through the electromagnet 16 and the connecting iron block 17, moves the grate plate 2, causing it to detach from the crusher body 1 through the through hole 5, thus completing the disassembly of the grate plate 2. Place the grate bar 2 that needs to be replaced on the surface of the upper plate frame 3 in advance, and magnetically connect the electromagnet 16 to the connecting iron block 17 on the side of the grate bar 2 away from the crusher body 1. Then, start the fixed motor 14 of the conveying device on the upper plate frame 3, so that the fixed motor 14 drives the slider 15 to move through the lead screw 13. The slider 15 moves the grate bar 2 on the upper plate frame 3 towards the crusher body 1 through the electromagnet 16, so that the grate bar 2 is inserted into the crusher body 1 through the through hole 5, thereby completing the replacement of the grate bar 2.
