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.

[0026] Reference Figure 2 , Figure 4 and Figure 5 As shown, one embodiment of this utility model is provided: a multi-specification adaptable walnut screener, including a base 1, with connecting plates 3 on both sides of the inner wall of the base 1, and a pull plate 4 slidably connected to the inner wall of the connecting plate 3. Connecting frames 8 are fixedly connected to both ends of the screening cylinder 10, and slots 9 are opened on the inner wall of the connecting frames 8. Blocks 6 are provided on the inner wall of the slots 9, and their shapes fit the slots 9. The outer walls of the blocks 6 are slidably connected to the inner wall of the connecting plate 3. Connecting rods 5 are rotatably connected to both sides of the inner wall of the pull plate 4, and the other end of the connecting rods 5 is rotatably connected to the inner wall of the blocks 6. Bolts 7 are provided on the inner wall of the pull plate 4. Threaded grooves are opened on the inner wall of the connecting plate 3, and the outer walls of the bolts 7 are all located on the inner wall of the threaded grooves. A groove is opened at one end of the connecting plate 3 inward, and the width of the connecting frame 8 is equal to the width of the inner wall of the groove, for the assembly and disassembly of the screening cylinder 10.

[0027] Specifically, during installation, first manually rotate the connecting plates 3 on both sides to an appropriate angle, then insert the connecting frames 8 at both ends of the screening cylinder 10 into the grooves. After installation, push the pull plate 4 backward to engage the locking block 6 into the slot 9, and then rotate the bolt 7 in the opposite direction to complete the installation. By rotating the bolt 7 and pulling the pull plate 4, the screening cylinder 10 can be removed. This simplifies the disassembly process, reduces the time and manpower required for disassembly, facilitates quick cleaning of clogged screen holes, and allows for the repair or replacement of worn parts. It also facilitates flexible switching of screening cylinders 10 with different apertures according to the walnut specifications, improving equipment adaptability and production efficiency, and reducing the impact of downtime maintenance on the processing progress.

[0028] Reference Figure 1 and Figure 3 As shown, a motor 11 is fixedly connected to the inner wall of the base 1, and universal couplings are fixedly connected to the outer ends of the connecting plates 3. A motor 2 is fixedly connected to the left end of the base 1. A feed inlet 16 is opened at the left end of the screening cylinder 10. A baffle 17 is detachably connected to the left side inside the screening cylinder 10. Both sides of the inner wall of the base 1 are rotatably connected to the outer ends of the universal couplings. The drive end of the motor 2 is fixedly connected to the right end of the left universal coupling. A movable frame 14 is slidably connected to the inner wall of the base 1. Multiple discharge rods 15 are fixedly connected to the front end of the movable frame 14. The diameter of the discharge rods 15 is equal to the diameter of the smallest screening hole of the screening cylinder 10. A rotating frame 12 is fixedly connected to the drive end of the motor 11. A rotating rod 13 is rotatably connected to the bottom end of the rotating frame 12. The other end of the rotating rod 13 is rotatably connected to the inner wall of the movable frame 14. The screening holes opened on the inner wall of the screening cylinder 10 gradually increase in size from left to right to discharge walnuts from the inner wall of the screening cylinder 10.

[0029] Specifically, a controller is fixedly connected to the right end of the base 1. The controller is electrically connected to motor 2 and motor 11. The screening holes of the screening cylinder 10 are of different diameters from left to right to accommodate walnuts of different sizes. The largest screening hole is large enough to discharge the largest walnuts. By setting a movable frame 14 and a discharge rod 15 on the rear side, the walnuts stuck inside the screening cylinder 10 can be removed, which can quickly clear blockages, prevent equipment jamming, reduce damage to the screening cylinder, ensure smooth screening, and improve the stability and ease of use of the equipment.

[0030] Working principle: First, remove the baffle 17 from the screening cylinder 10 and add walnuts into the screening cylinder 10 through the feed inlet 16. Then, start motor 2 via the controller. Motor 2 drives the universal coupling and the screening cylinder 10 to rotate, screening the walnuts inside. The walnuts are screened through the screening holes of the screening cylinder 10 and discharged downwards. After screening, if walnuts are stuck inside the screening holes, manually rotate the screening cylinder 10 to align the screening hole with the stuck walnuts with the discharge rod 15 on the rear side, and start motor 11. 1. The rotating frame 12 is rotated, which in turn rotates the rotating rod 13, and moves the movable frame 14 and the discharge rod 15 forward. The discharge rod 15 pushes out the walnuts stuck inside the screening holes, thus completing the discharge. Next, when it is necessary to disassemble the screening cylinder 10, first rotate the bolt 7 to remove the bolt 7 from the threaded groove, and pull the pull plate 4 forward. The pull plate 4 drives the connecting rod 5 to rotate, and drives the two side blocks 6 to pull upward, removing the blocks 6 from the slots 9. Then the screening cylinder 10 can be removed according to the path of the groove, thus completing the disassembly.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
