[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please refer to Figures 1-3 This embodiment provides an artificial bone crushing device 100, which includes a main body 110, a crushing roller group 120, a drive assembly 130, and a screening assembly 140. The main body 110 is provided with an inner cavity 111, and a feed inlet 112 and a discharge outlet 113 are respectively provided on opposite sides of the main body 110; the crushing roller group 120 is rotatably disposed in the inner cavity 111 and is connected to the drive assembly 130 connected to the main body 110. The screening component 140 is disposed in the inner cavity 111 and is adjacent to the discharge port 113.

[0025] Please refer to Figures 1-3 The working principle of the artificial bone crushing device 100 is as follows: The artificial bone crushing device 100 includes a main body 110, a crushing roller assembly 120, a drive assembly 130, and a screening assembly 140. The main body 110 is provided with an inner cavity 111, and an inlet 112 and an outlet 113 are respectively provided on opposite sides of the main body 110. The crushing roller assembly 120 is rotatably disposed in the inner cavity 111 and is connected to the drive assembly 130 connected to the main body 110. The screening assembly 140 is disposed in the inner cavity 111 and is adjacent to the outlet 113. Therefore, during use, the artificial bone crushing device 100 can drive the crushing roller group 120 located in the inner cavity 111 to rotate through the drive component 130, thereby crushing the artificial bone introduced into the inner cavity 111 through the feed port 112. After being crushed, it will fall onto the screening component 140 adjacent to the discharge port 113 for screening. After screening, it will be discharged through the discharge port 113. This structural arrangement allows the artificial bone crushing device 100 to complete the crushing and screening of artificial bone, so that crushing and screening can be carried out continuously in the same device, thereby improving the utilization efficiency of artificial bone. Moreover, the artificial bone crushing device 100 has a simple structure and is easy to use, thereby reducing the operating cost.

[0026] It should be noted that the parts of the existing crushing equipment that come into contact with the artificial bone are not easy to clean, which can easily cause contamination of the artificial bone in the medical device. Therefore, in this embodiment, in order to facilitate the arrangement, installation and cleaning of the equipment, the feed inlet 112 and the discharge outlet 113 can be detachably connected to the main body 110 for easy cleaning after use. In addition, in order to facilitate the cleaning of the crushing roller assembly 120, the crushing roller assembly 120 can be detachably connected and installed. A movable chamber door 101 can be provided on one side of the main body 110 so that the inner cavity 111 can be opened by opening the movable chamber door 101 to facilitate cleaning or maintenance of the device.

[0027] Further, please refer to Figures 1-3 In this embodiment, to facilitate the sieving of the crushed artificial bone, the sieving assembly 140 includes at least one sieving disc 141 connected to the main body 110. To facilitate the selection and adjustment of the crushed particle size, the sieving disc 141 can be replaced.

[0028] In other embodiments of this utility model, the screening assembly 140 may further include a plurality of screening discs 141 connected to the main body 110, and at least one of them is movably connected to the main body 110; each screening disc 141 has a plurality of guide holes arranged in an array; the plurality of screening discs 141 are arranged in parallel, and the diameter of the guide holes on the screening discs 141 gradually decreases from the feed inlet 112 to the discharge outlet 113; thus, the particle size can be adjusted by adjusting one or more of the screening discs 141, and this arrangement of multiple screening discs 141 can improve the screening quality.

[0029] Based on the above structure, in order to improve the screening efficiency of the screening assembly 140 and avoid material blockage, the screening assembly 140 includes a vibration mechanism for driving one or more screening discs 141 to vibrate. It should be noted that the vibration mechanism can employ existing technology, and its purpose is to improve the screening efficiency and avoid material blockage by causing one of the multiple movable screening discs 141 to vibrate.

[0030] To facilitate the disassembly and assembly of the screening assembly 140 for adjustment and maintenance, a slot communicating with the inner cavity 111 is provided on one side of the main body 110. The slot is used for the screening assembly 140 to slide into or out of the inner cavity 111. Furthermore, support platforms are provided on opposite sides of the inner cavity 111 for placing the screening assembly 140, and the two support platforms are located on both sides of the slot.

[0031] With this configuration, the screening assembly 140 can be slid into the inner cavity 111 through a slot and onto the support platform, thereby improving its stability and flexibility in use.

[0032] Based on the above structure, please refer to Figures 1-3 When the crushing roller group 120 is configured, the crushing roller group 120 includes two crushing rollers 121, and both crushing rollers 121 are rotatably connected to the main body 110; when the drive assembly 130 is configured, the drive assembly 130 includes two drive motors 131, both drive motors 131 are connected to the outside of the main body 110, and each drive motor 131 is driven to one crushing roller 121.

[0033] Thus, the two crushing rollers 121 can be driven independently in this way. In other embodiments of this utility model, the two crushing rollers 121 can also be connected by a transmission, and thus driven by a single motor.

[0034] Please refer to Figures 1-5 Based on the independent driving of the two crushing rollers 121, in order to adjust the distance between the two crushing rollers 121 as needed so that the equipment can obtain artificial bone of different particle sizes and reduce raw material waste, the artificial bone crushing device 100 also includes a spacing adjustment mechanism 150, which is used to adjust the spacing between the two crushing rollers 121.

[0035] Specifically, when configuring the spacing adjustment mechanism 150, its function is to adjust the spacing between the two crushing rollers 121, thereby obtaining artificial bone with different particle sizes. Based on this, this embodiment is described with the example of making one of the crushing rollers 121 movable; in other embodiments of this utility model, both crushing rollers 121 can also be movable. It should be noted that when one or both crushing rollers 121 are movable, they move in the direction of increasing or decreasing the spacing between the two crushing rollers 121.

[0036] The spacing adjustment mechanism 150 includes two movable mounting plates 151; the main body 110 has strip holes 152 on both sides opposite to each other, and along the extension direction of the strip holes 152, each strip hole 152 has multiple fixing holes on both sides. Two movable mounting plates 151 correspond one-to-one with two strip holes 152, and each movable mounting plate 151 is connected to one of the fixing holes on the side of the corresponding strip hole 152 by a fastener, and the strip hole 152 is closed. One of the crushing rollers 121 is rotatably connected to two movable mounting plates 151 at both ends, and the two ends of the crushing roller 121 are slidably engaged with two strip holes 152.

[0037] Therefore, with the above-described structural arrangement, the two ends of the crushing roller 121 can be rotatably connected to two movable mounting plates 151. The two movable mounting plates 151 are fixedly connected to the main body 110 by means of fixing members and fixing holes, thereby closing the strip hole 152 and keeping the crushing roller 121 rotatable. When adjustment is required, the fixing members can be adjusted to connect to different fixing holes, so that the movable mounting plates 151 can be adjusted in position along the extension direction of the strip hole 152, thereby driving the crushing roller 121 to slide relative to the strip hole 152, thereby increasing or decreasing the distance between the two crushing rollers 121.

[0038] It should also be noted that, in the above structure, the installation of the movable door 101 and the movable mounting plate 151, etc., can maintain its overall sealing and avoid dust pollution to the workshop environment during the artificial bone crushing process.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
