[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0026] See also Figures 1-6 , this embodiment provides the following technical solutions:

[0027] like Figure 1-Figure 3 As shown, a hard disk crushing device includes: a crusher body 1, an expandable hard disk feeding hopper 101 is fixedly installed on the upper surface of the crushing cylinder 102 of the crusher body 1, and a constricted discharge hopper 103 is fixedly installed on the lower surface of the crushing cylinder 102. The constricted discharge hopper 103 is flush with the docking groove 104. The docking groove 104 is opened at one end of the crusher body 1, and the docking groove 104 is arranged with a conveying and screening mechanism 2.

[0028] The conveying and screening mechanism 2 is flush with the constricted discharge hopper 103 , and the constricted discharge hopper 103 allows the crushed hard disk fragments to fall accurately onto the upper surface of the conveying and screening mechanism 2 through the constriction.

[0029] Through the design of the crusher body 1, the expandable hard disk feeding hopper 101, the crushing cylinder 102, the constricted discharge hopper 103 and the conveying and screening mechanism 2, when the hard disk is crushed, the hard disk can be guided from the expandable hard disk feeding hopper 101 into the crushing cylinder 102 for crushing, and the crushed hard disk will fall from the constricted discharge hopper 103 to the upper surface of the conveying and screening mechanism 2, and the conveying and screening mechanism 2 can convey and store the crushed hard disk debris. In the process of conveying the hard disk debris by the conveying and screening mechanism 2, since the surface of the hard disk disk is covered with a layer of magnetic material, such as iron oxide or cobalt-based alloy, when the hard disk is crushed into small particles or debris, these magnetic materials still have magnetism, so During the transportation process, the conveying and screening mechanism 2 will adsorb the magnetic materials, including the disks storing data, and the non-magnetic materials will be transported to the end along the conveying and screening mechanism 2, and the magnetic materials will be transported to the bottom end of the conveying and screening mechanism 2 and scraped down, thereby achieving the purpose of separating and storing the shredded hard disks, allowing staff to intuitively observe the status of the shredded disks, so that staff can promptly discover disk fragments that have not been effectively destroyed, so that they can effectively destroy the disk parts containing data, reducing the risk of data leakage. Because magnetic materials are usually the main part of hard disk data recording, this process can ensure that sensitive data is completely destroyed.

[0030] like Figure 4-Figure 6 As shown, the conveying and screening mechanism 2 includes a Z-shaped frame 201, a transmission column 210 is rotatably installed in the Z-shaped frame 201, and a conveyor belt 202 is sleeved on the outer surface of the transmission column 210. A limiting column 204 is fixedly installed in the Z-shaped frame 201, and the limiting column 204 contacts the upper and lower surfaces of the conveyor belt 202, so that the conveyor belt 202 is limited to a Z shape to match the Z-shaped frame 201;

[0031] A motor 205 is fixedly mounted on one end of the Z-shaped frame 201 , and an output shaft of the motor 205 is fixedly mounted on one end of the transmission column 210 .

[0032] A magnetic strip 203 is embedded in the outer surface of the conveyor belt 202, and the magnetic strip 203 can absorb the broken discs.

[0033] A guide plate 206 is fixedly mounted on the lower surface of the Z-shaped frame 201 , and a storage box 207 is slidably inserted into the guide plate 206 . The storage box 207 is separated at both ends.

[0034] A fastening frame 209 is fixedly installed between the Z-shaped frames 201, and a scraper plate 208 is fixedly installed at one end of the fastening frame 209. The scraper plate 208 is attached to the lower end of the outer surface of the conveyor belt 202 and the magnetic strip 203;

[0035] The scraper plate 208 is flush with the partition slot at the rear end of the storage box 207 , and the end of the conveyor belt 202 is flush with the partition slot at the front end of the storage box 207 .

[0036] Through the design of the conveyor belt 202, the magnetic strip 203, the storage box 207 and the scraper plate 208, the shredded hard disk will fall from the constricted outlet hopper 103 to the upper surface of the conveyor belt 202, and the magnetic strip 203 set on the surface of the conveyor belt 202 will absorb the disk debris of the hard disk. Because the surface of the hard disk is covered with a layer of magnetic material, such as iron oxide or cobalt-based alloy, when the hard disk is crushed into small particles or debris, these magnetic materials still have magnetism and will be attracted by the magnetic strip 203. The non-magnetic materials will be transported to the end along the conveyor belt 202 and fall into the storage box 207 and stored in one group of separation slots of the storage box 207. The magnetic The debris will continue to be conveyed by the conveyor belt 202 until it touches one end of the scraper plate 208 and will be dropped by the scraper, causing the magnetic debris to fall into another set of partition slots in the storage box 207 for storage, thereby achieving the purpose of separating and storing the shredded hard disks. The staff can intuitively observe the condition of the shredded disks, so that the staff can promptly discover the disk fragments that have not been effectively destroyed, so that they can effectively destroy the disk parts containing data, reducing the risk of data leakage, and the classified debris can be recycled more efficiently. After the magnetic materials and non-magnetic materials are separated, they can be sent to different recycling and processing institutions respectively, thereby improving the efficiency and quality of resource recovery.

[0037] According to the above technical solution, the working steps of this solution are summarized and sorted out: when the hard disk is crushed, the hard disk can be guided from the expandable hard disk feeding hopper 101 into the crushing cylinder 102 for crushing, and the crushed hard disk will fall from the constricted discharge hopper 103 to the upper surface of the conveyor belt 202, and the magnetic strips 203 provided on the surface of the conveyor belt 202 will absorb the disk fragments of the hard disk, because the surface of the hard disk disk is covered with a layer of magnetic material, such as iron oxide or cobalt-based alloy. When the hard disk is crushed into small particles or debris, these magnetic materials still have magnetism, so they will be attracted by the magnetic strips 203, and will not have magnetism. The magnetic material will be transported along the conveyor belt 202 to the end and fall into the storage box 207, and stored in one group of separation slots of the storage box 207, while the magnetic debris will continue to be transported by the conveyor belt 202 until it touches one end of the scraper plate 208, and then it will be dropped by the scraper, causing the magnetic debris to fall into another group of separation slots of the storage box 207 for storage, thereby achieving the purpose of separating and storing the shredded hard disks, allowing the staff to intuitively observe the status of the shredded disks, so that the staff can promptly discover the disk fragments that have not been effectively destroyed, and then dump them for a second shredding.

[0038] In summary: it can effectively destroy the part of the disk containing data, reduce the risk of data leakage, and the debris after classification can be recycled more efficiently. After the magnetic material and non-magnetic material are separated, they can be sent to different recycling and processing institutions respectively, improving the efficiency and quality of resource recovery.
