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] Reference Figures 3-5 As shown, one embodiment of this utility model provides a rapid walnut shell-breaking and separating device, including an outer shell 1, a connecting frame 4 provided on the inner wall of the outer shell 1, a rotating handle 5 rotatably connected to the inner wall of the connecting frame 4, rubber crushing rollers 11 fixedly connected to both sides of the right end of the connecting frame 4, slots 10 provided on both sides of the inner wall of the outer shell 1, and locking blocks 8 provided on the inner wall of each slot 10, the shape of the locking blocks 8 fitting the slots 10, and the outer walls of the locking blocks 8 slidably connected to the inner wall of the connecting frame 4, a threaded rod 6 fixedly connected to the top of the rotating handle 5, a sliding frame 7 threadedly connected to the outer wall of the threaded rod 6, and the outer wall of the sliding frame 7 slidably connected to the inner wall of the connecting frame 4, protrusions fixedly connected to both sides of the right end of the sliding frame 7, and grooves 9 provided on the inner wall of each locking block 8, the inner walls of the grooves 9 slidably connected to the outer walls of the protrusions, for disassembling and assembling the rubber crushing rollers 11.

[0019] Specifically, during installation, first insert the rubber crushing roller 11 and connecting frame 4 into the outer casing 1. After installation, rotate the handle 5 in the opposite direction to insert the locking blocks 8 on both sides into the slots 10 to complete the installation. A controller is set at the front end of the outer casing 1. The controller is electrically connected to motor 1 2, fan 12 and motor 2 13. The diameter of the bolt rod 3 decreases from left to right to accommodate walnuts of different sizes. By rotating the handle 5, the limiting position of the rubber crushing roller 11 on both sides can be released, greatly simplifying the operation process, shortening maintenance and replacement time, avoiding damage to the roller shaft or transmission structure due to improper disassembly and assembly, reducing equipment wear, and adapting to the frequent maintenance needs in large-scale processing scenarios, reducing downtime, ensuring continuous and efficient operation, and further reducing equipment maintenance costs and manual operation intensity.

[0020] Reference Figure 1 , Figure 2 and Figure 6 As shown, a second motor 13 is fixedly connected to the left end of the outer casing 1, and a first motor 2 is fixedly connected to the right end of the outer casing 1. A spiral rod 3 is fixedly connected to the drive end of the first motor 2. A discharge port 19 is opened on the right side of the inner wall of the outer casing 1. Slider blocks 15 are slidably connected to both sides of the inner wall of the outer casing 1. A connecting rod 17 is sleeved on the inner wall of each slider 15. A screen 18 is rotatably connected to the inner wall of the outer casing 1. The outer wall of the connecting rod 17 is rotatably connected to the inner wall of the screen 18. A raised roller 14 is fixedly connected to the drive end of the second motor 13. The outer wall of the raised roller 14 is set at the bottom end of the screen 18. A tension spring 16 is fixedly connected to the bottom end of each slider 15. The other end of the tension spring 16 is fixedly connected to the inner wall of the outer casing 1. Multiple fans 12 are fixedly connected to the left side of the inner wall of the outer casing 1. Filter screens are set on both sides of each fan 12. The inner wall of the outer casing 1 is fixedly connected to the outer wall of the filter screen for screening walnut kernels and walnut shells.

[0021] Specifically, when the screen 18 vibrates, the connecting rod 17 moves on the inner wall of the slider 15. The size of the holes on the screen 18 is sufficient to discharge the walnut kernels. The screen 18 is made of stainless steel. By using air blowing and screening, the kernels are screened. The airflow can blow away light broken shells, and the screen 18 separates the kernels and impurities according to size. This solves the problem of residual broken shells when simply screening, and avoids damage to the kernels. It meets the need for rapid separation after shelling, improves separation accuracy and efficiency, and reduces labor costs.

[0022] Working principle: First, walnuts are added into the shell 1 through the upper feed inlet. The controller starts motor 2, motor 3, and fan 12. Motor 2 drives the screw rod 3 to rotate, causing the falling walnuts to be conveyed to the right and contacted and squeezed by the rubber crushing rollers 11 on both sides, thus removing the shells. After shelling, the walnut kernels and shells fall onto the screen 18. Simultaneously, during this falling process, the fan 12 blows air inward, blowing smaller walnut shells to the right and discharging them from the discharge port 19. Motor 3 drives the raised roller 14 to rotate. The raised roller 14 contacts the screen 18, causing the screen 18 to rotate and the sliders 15 on both sides to slide upward. Once the raised roller 14 is no longer in contact with the screen... After the screen 18 contacts, the spring 16 pulls the slider 15 and the screen 18 downwards, thereby repeatedly causing the screen 18 to vibrate. This screens the walnut kernels and larger walnut shells on the upper side. The walnut kernels fall downwards through the holes of the screen 18, while the walnut shells are conveyed to the right and discharged through the outlet 19, thus completing the shell breaking and separation. When it is necessary to disassemble the rubber crushing roller 11, simply rotate the handle 5. The handle 5 drives the threaded rod 6 to rotate, and the threaded rod 6 drives the sliding frame 7 on the outer wall to move downwards, causing the protrusion to slide on the inner wall of the sliding groove 9. This pulls the locking blocks 8 on both sides to slide inwards, allowing the locking blocks 8 to be removed from the locking groove 10. This allows the connecting frame 4 and the rubber crushing roller 11 to be removed, completing the disassembly.
