[0023] The base 1 serves as the support structure of the entire sorting machine, and other main components are fixedly connected to its upper surface. The motor 2 is fixedly connected to the upper surface of the base 1 and is the power source of the sorting machine. A plurality of support columns 3 are symmetrically and fixedly connected to the upper surface of the base 1 and are used to support the sorting device 4 above. The sorting device 4 is jointly supported by the support columns 3 and includes key components such as a stirring chamber 5. The stirring chamber 5 is used for stirring and sorting nuts. A feeding chamber 6 is fixedly connected to its upper surface, and the feeding chamber 6 is used to place the nuts to be sorted. A rotating groove 7 is provided on its lower surface and is connected to the output end of the motor 2. The rotating groove 7 is opened on the lower surface of the feeding chamber 6 and allows the rotating column 8 to pass through and be rotatably connected thereto. The top of the output end of the motor 2 is fixedly connected with a rotating column 8, which penetrates into the interior of the rotating groove 7 and is fixedly connected with a wedge-shaped disc 14 inside the stirring chamber 5. A cleaning chamber 9 is opened on the left side of the inner wall of the stirring chamber 5, and a cleaning disc 10 is rotatably connected inside it. It is used to clean the impurities and residues on the surface of the nuts in the stirring chamber 5. A transmission column 11 is fixedly connected to its upper surface, and the transmission column 11 rotates synchronously through a transmission belt 13. A transmission groove 12 is opened on the outer sidewall of the rotating column 8 and is located inside the rotating groove 7 and is used to cooperate with the transmission belt 13 to realize the synchronous rotation of the cleaning disc 10 and the rotating column 8. The wedge-shaped disc 14 is fixedly connected to the outer sidewall of the rotating column 8 and is located inside the stirring chamber 5 and promotes the stirring and sorting of nuts by rotation. The extrusion holes 34 are holes with different specifications and sizes, and are fixedly communicated with the outer sidewall of the stirring chamber 5 to allow nuts meeting specific conditions to be pushed out. An extrusion pipe 15 is fixedly connected to the outer sidewall of the extrusion hole 34 and is used to guide the pushed-out nuts into the collection container. The feed port 16 is fixedly communicated between the feeding chamber 6 and the stirring chamber 5 to allow the nuts to be sorted to enter the stirring chamber 5 from the feeding chamber 6. A cleaning block 28 is fixedly connected to the lower surface of the cleaning disc 10. The cleaning disc 10 is made of soft cloth and will not damage the nuts when rotating with the cleaning disc 10 to clean the impurities and residues. This nut sorting machine drives the rotating column 8 to rotate through the motor 2, and then drives the wedge-shaped disc 14 to stir the nuts in the stirring chamber 5 to achieve sorting. At the same time, the rotational force of the rotating column 8 is transmitted to the cleaning disc 10 through the transmission belt 13, so that the cleaning block 28 cleans the impurities in the stirring chamber 5. The nuts meeting specific conditions are collected through the extrusion holes 34 and the extrusion pipes 15 to realize the automatic sorting process.

[0024] Such as Figures 1-5As shown, a circular cavity 17 is fixedly connected to the lower surface of the stirring cavity 5. The output end of the motor 2 is fixedly connected with a plurality of blowing blades 18 inside the circular cavity 17. An air outlet hole 19 is formed in the outer side wall of the circular cavity 17. A plurality of circular grooves 20 are formed in the outer side wall of the base 1. A guiding groove 21 is formed in the right side inside the circular groove 20. A clamping post 22 is clamped and connected inside the circular groove 20. A limiting block 23 is formed on the outer side wall of the clamping post 22. Positioning grooves 24 are formed on the upper surface of the base 1 above the circular grooves 20. A positioning post 25 is clamped and connected inside each positioning groove 24. A positioning hole 26 is formed on the outer side wall of the clamping post 22. The positioning post 25 is clamped through the positioning groove 24 and fixedly connected with a storage cavity 27 at one end of the inner part of the positioning hole 26 away from the circular groove 20;

[0025] A circular cavity 17 is fixedly connected to the lower surface of the stirring cavity 5. This circular cavity is designed to accommodate a part of the output end of the motor 2 and provide a stable working environment for it. The output end of the motor 2 is fixedly connected with a plurality of blowing blades 18 inside the circular cavity 17. These blowing blades 18 can generate air flow as the motor 2 rotates, and are used to blow out gas through the air outlet hole 19 during the stirring process. When the nut falls out, the blown air will blow away the impurities that fall out at the same time, preventing them from falling into the storage cavity 27 and playing a role in helping to remove impurities. A plurality of circular grooves 20 are formed in the outer side wall of the base 1. A guiding groove 21 is further formed in the right side inside each circular groove 20. These designs are for installing the limiting block 23 to prevent the installation direction from being inconvenient. Positioning grooves 24 are formed on the upper surface of the base 1 above the circular grooves 20. A positioning post 25 is clamped and connected inside each positioning groove 24. This design is usually used to ensure the precise alignment and fixation between components and is used to install the clamping post 22. A positioning hole 26 is formed on the outer side wall of the clamping post 22. The positioning post 25 is clamped through the positioning groove 24 and fixedly connected with a storage cavity 27 at one end of the inner part of the positioning hole 26 away from the circular groove 20.

[0026] As Figures 1-5 shown, a circular chute 30 is formed in the inner side wall of the stirring cavity 5. A circular rolling groove 31 is formed in the outer side wall of the wedge-shaped disc 14. A ball 32 is connected in a rolling manner between the chute 30 and the rolling groove 31;

[0027] The rolling of the ball 32 between the chute 30 and the rolling groove 31 replaces the direct contact between the wedge-shaped disc 14 and the inner wall of the stirring chamber 5. This rolling friction is smaller than sliding friction, can significantly reduce wear, and extend the service life of the equipment. Due to the reduction of friction, the rotation of the wedge-shaped disc 14 in the stirring chamber 5 will be smoother, thereby improving the operation efficiency of the entire separator and enhancing stability. The rolling of the ball 32 also helps to maintain the stable rotation of the wedge-shaped disc 14 in the stirring chamber 5, reducing vibrations and noises caused by imbalance. The ball 32 is an independent component. If it is worn or damaged, it can be replaced separately without replacing the entire stirring chamber 5 or the wedge-shaped disc 14, thus reducing the maintenance cost. In summary, the design of the chute 30, the rolling groove 31 and the ball 32 is an effective anti-friction and efficiency-enhancing measure, which is of great significance for improving the performance and reliability of the nut separator.

[0028] As Figures 1-5 shown, an anti-slip pad 33 is fixedly connected to the lower surface of the base 1;

[0029] The main function of the anti-slip pad 33 is to increase the friction between the base 1 and the placement surface such as the ground, workbench, etc., thereby preventing the equipment from sliding or shifting due to external forces such as vibration, impact, etc. during use, ensuring the stable operation of the equipment, and protecting the placement surface. The anti-slip pad 33 is usually made of soft, wear-resistant and corrosion-resistant materials, which can reduce the direct pressure of the base 1 on the placement surface to a certain extent and prevent the sharp edges or corners of the base 1 from scratching the placement surface.

[0030] All electrical components mentioned in this article are electrical components that exist in reality.

[0031] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention also belong to the protection scope of the present invention.
