[0017] 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.

[0018] To address the issue that adjusting the size of existing multi-stage vibrating screens requires disassembling the entire screen frame, necessitating machine shutdown and resulting in a lengthy process; please refer to... Figure 1-2 The present invention provides the following solution:

[0019] A multi-layer screen grading device includes a motor support 1 and a screening disc 2. The screening disc 2 is composed of multiple screen frames 201, which are connected by locking clamps 205. A cover 202 is provided on the top of the screening disc 2, and a feeding port 203 is provided on the outer surface of the cover 202. A tray 101 is provided between the screening disc 2 and the motor support 1. The tray 101 is connected to the screen frames 201 by locking clamps 205. A support spring 102 is provided between the tray 101 and the motor support 1. A vibrating motor is provided inside the motor support 1.

[0020] In this embodiment, the multi-layer screen grading equipment uses the excitation force generated by a vibrating motor as its working power source. After the equipment starts, the high-frequency, low-amplitude vibration generated by the vibrating motor is transmitted to the support spring 102 through the motor support 1, thereby driving the entire sieving disc 2 system to perform three-dimensional rotary vibration. The material is fed in through the feeding port 203 of the top cover 202 and is evenly dispersed on the surface of the uppermost screen 2011 under the action of vibration. Under the combined action of centrifugal force, vibration inertial force and gravity, material particles smaller than the aperture of the current screen 2011 quickly pass through the screen and fall to the lower screen surface to continue to be graded; materials larger than the aperture move spirally along the screen surface and are finally discharged through the discharge port 204 of the current screen, realizing multi-stage particle size separation.

[0021] A screening outlet 204 is provided on one side of the layer screen frame 201, extending into the interior of the layer screen frame 201. A mesh screen 2011 is provided inside the layer screen frame 201, and a sealing ring 2016 is provided on the outer side of the bottom of the mesh screen 2011. A bottom screen plate 2013 is provided below the mesh screen 2011. The bottom screen plate 2013 and the layer screen frame 201 are integrated. Multiple ring buckles 2014 are provided between the bottom screen plate 2013 and the mesh screen 2011. The ring buckles 2014 are connected to the bottom screen plate 2013 through slots. Multiple rubber balls 2015 are provided inside the ring buckles 2014. The top of the ring buckles 2014 is attached to the mesh screen 2011. The mesh screen 2011 is connected to the layer screen frame 201 through a pull-out groove 2012. The sealing ring 2016 is attached to the layer screen frame 201.

[0022] In this embodiment, the core innovation of the equipment lies in its unique interlayer rapid adjustment and maintenance structure. Each layer of screen frame 201 can be quickly locked or separated by locking clamps 205. When it is necessary to replace or clean a certain layer of screen 2011, it is not necessary to disassemble the entire screening disc 2; simply loosen the locking clamps 205 of that layer to separate the screen frame 201 individually. The screen 2011 is embedded inside the layer screen frame 201 through the pull-out groove 2012 and is quickly snapped and fixed to the bottom screen disc 2013 through the bottom ring buckle 2014 structure. The rubber ball 2015 set inside the ring buckle 2014 continuously bounces during vibration, generating a self-cleaning effect on the bottom surface of the screen 2011, effectively preventing screen hole blockage. The sealing ring 2016 ensures the sealing of the interlayer joints, preventing material leakage or cross-contamination.
