In the process of the shell-kernel mixture falling from the discharge pipe 22 to the silo 23, under the action of the fan 231, the lighter walnut shells are blown to one side of the silo 23, and the heavier walnut kernels fall on the conveyor belt 3 and continue to be transported to the camera 311.

[0052] When the paddle 233 provided by the present invention is in use, the paddle 233 is provided to facilitate dispersion of the stacked shell-kernel mixture, so that the shell-kernel mixture is spread flat on the conveyor belt 3 individually, and the shell-kernel mixture on both sides is gathered together by the limiting plate 234, so as to facilitate separate transportation from the walnut shells at a later stage.

[0059] Working principle: walnuts pass through the feed hopper 11 and enter the rolling cylinder 13. By turning on the first motor 12, the first motor 12 drives the rotating rod 121 to rotate through the output shaft, and the rolling roller 122 is driven to rotate through the rotating rod 121. The walnut shells are broken by the rolling friction between the rolling roller 122 and the rolling cylinder 13. The walnuts fall on the filter plate 17 after the shells are broken. The rotating rod 121 drives the stirring paddle 123 to rotate while rotating. The stirring paddle 123 stirs the shell-kernel mixture, which will cause the broken walnut shells to fall through the filter plate 17. The broken walnut shells at the bottom of the outer cylinder 1 are scraped into the bag collector 16 by the scraper 124; at the same time, some of the walnut shells adhering to the walnut kernels will also be stirred and separated. The walnut shell and kernel mixture is separated to facilitate the separation of the shell and kernel. The walnut shell and kernel mixture is transported to the discharge pipe 22 through the conveying cylinder 2. When the walnut shell is discharged through the discharge pipe 22, the fan 231 is turned on. Since the walnut shell is light in weight, it is easy to be blown into the silo 23 by the fan 231. The rest will be scattered on the conveyor belt 3. Under the action of the paddle 233, the shell and kernel mixture is spread out one by one on the conveyor belt 3. Under the action of the conveyor belt 3, it is sent to the camera 311 to collect the image area. The camera 311 collects images containing multiple materials in real time. The model trained by YOLOv8 is used to classify and identify the materials contained in the image and predict the category information and location information of each material. The result is converted into a voltage signal by a D / A converter and transmitted to the controller 312. The third motor 323, the second electric push rod 325 and the cylinder 326 are controlled according to the instruction of the controller 312.
