Description

Technical Field

[0001] This utility model relates to the field of Torreya grandis kernel production technology, and in particular to a shelling device for producing Torreya grandis kernels. Background Technology

[0002] Torreya nuts, also known as Chinese torreya seeds, are the seeds of the Torreya tree. Resembling olives in appearance, they have a hard, brown outer shell encasing a pale yellow kernel. The kernel is crisp and has a delicate texture. Its unique flavor initially carries a pine-like aroma, followed by a sweet and slightly astringent aftertaste, accompanied by a distinctive oily fragrance. This complex flavor stems from its rich nutritional content.

[0003] In existing equipment, most of the shelling operations for Torreya grandis kernels are carried out manually using shelling machinery. This may result in the kernels being damaged due to excessive force during the shelling process, thus affecting the product value and reducing its practicality. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-5 A shelling device for producing shelled torreya nuts includes a support frame 1, an L-shaped support plate 2 fixedly connected to the rear of the support frame 1, an electric push rod 3 fixedly installed at the front of the upper surface of the L-shaped support plate 2, a drive rod 4 fixedly connected to the power output end of the electric push rod 3, and a pressure plate 5 fixedly connected to the lower surface of the drive rod 4.

[0025] A working plate 6 is fixedly connected to the upper surface of the load-bearing frame 1. Strip sleeves 7 are fixedly connected to the left and right sides of the upper surface of the working plate 6. Guide grooves 8 are opened inside the two strip sleeves 7. Push plates 9 are movably connected inside the two guide grooves 8. Push handles 10 are fixedly connected to the right side of the push plates 9. An auxiliary shelling assembly 11 is fixedly connected to the front of the load-bearing frame 1. The load-bearing frame 1 serves as the foundation of the entire device and supports the various components. The L-shaped support plate 2 provides an installation position for the electric push rod 3. When the electric push rod 3 is started, its power output end drives the drive rod 4 to move up and down, thereby causing the pressure plate 5 to move up and down accordingly. The working plate 6 is the main working surface for shelling Torreya grandis. After the Torreya grandis is placed on the working plate 6, the pressure plate 5 moves downward to apply pressure to the Torreya grandis, causing the outer shell of the Torreya grandis to develop large cracks or break directly.

[0026] The auxiliary shell-removal assembly 11 includes a circular sleeve 12, which is located directly in front of the load-bearing frame 1. A drive motor 13 is fixedly installed at the middle position on the right side of the circular sleeve 12. A drive rod 31 is fixedly connected to the power output end of the drive motor 13. A rotating rod 14 is fixedly connected to the left side of the drive rod 31. A crushing plate 15 is fixedly connected to the outer surface of the rotating rod 14. The circular sleeve 12 provides installation and protection space for the rotating structure inside the assembly. When the drive motor 13 starts, its power output end drives the drive rod 31 to rotate, thereby causing the rotating rod 14 connected to the left side of the drive rod 31 to rotate synchronously. The crushing plate 15 fixed on the outer surface of the rotating rod 14 will rotate at high speed together with the rotating rod 14. During the rotation, the crushing plate 15 can apply impact force to the torreya nuts that have entered the circular sleeve 12 and have undergone preliminary shelling treatment, further crushing the remaining shell, or helping to separate the shell from the torreya kernel. This, in conjunction with the shelling structure of the previous pressing plate 5, improves the overall shelling effect and ensures that the torreya kernel can be separated from the shell more thoroughly.

[0027] A connecting plate 16 is fixedly connected to the inner wall of the circular sleeve 12. An arc-shaped screening sleeve 18 is slidably connected to the lower surface of the connecting plate 16 via a slider 17. An arc-shaped screening mesh 19 is fixedly connected inside the arc-shaped screening sleeve 18. The connecting plate 16 on the inner wall of the circular sleeve 12 provides support for the screening structure. The arc-shaped screening sleeve 18 is slidably connected to the lower surface of the connecting plate 16 via the slider 17, which allows the arc-shaped screening sleeve 18 to move flexibly. When the crushing plate 15 crushes the shell of the Torreya grandis, the Torreya grandis kernel and the crushed shell will fall into the arc-shaped screening sleeve 18. The arc-shaped screening mesh 19 inside uses the difference in mesh size to allow the smaller crushed shells of the Torreya grandis kernel to pass through the mesh, while the larger crushed shells are left on the arc-shaped screening mesh 19, thereby achieving the initial separation of the two, improving the purity of the Torreya grandis kernel after shelling, and assisting in completing the shelling process.

[0028] The crushing plate 15 and the arc-shaped screening mesh 19 are interlocked in curvature. When the crushing plate 15 rotates, it can continuously strike the upper surface of the arc-shaped screening mesh 19, which can effectively screen the kernels and shells of Torreya grandis and improve the screening efficiency.

[0029] A base plate 20 is fixedly connected to the lower surface of the load-bearing frame 1, a collection box 21 is fixedly connected to the upper surface of the base plate 20, an impurity box 33 is movably connected to the rear of the upper surface of the base plate 20, a support block 22 is fixedly connected to the front of the upper surface of the base plate 20, and a blower sleeve 23 is fixedly connected to the upper surface of the support block 22. The collection box 21 is fixed to the upper surface of the base plate 20 and is mainly used to collect the Torreya kernels produced during the shelling process for convenient subsequent centralized processing and to keep the working environment clean. The support block 22 in front of the base plate 20 supports the blower sleeve 23, so that the blower sleeve 23 is at a suitable height and position. The blower sleeve 23 can generate airflow, which may be used to blow away the lighter shell fragments separated during the shelling process, further improving the separation effect of Torreya kernels from the shell, and improving the working efficiency of the entire shelling device.

[0030] A second drive motor 24 is fixedly installed at the rear of the blower sleeve 23. A movable rod 25 is fixedly connected to the front of the second drive motor 24 via a third drive rod. A drive wheel 26 is fixedly connected to the front of the movable rod 25. A transmission wheel 28 is connected to the outer surface of the drive wheel 26 via a transmission belt 27. When the second drive motor 24 is started, its power is transmitted to the movable rod 25 via the third drive rod, causing the movable rod 25 to rotate, which in turn drives the drive wheel 26 to rotate synchronously. Since the drive wheel 26 is connected to the transmission wheel 28 via the transmission belt 27, the rotation of the drive wheel 26 will drive the transmission wheel 28 to rotate together via the transmission belt 27.

[0031] A rotating shaft 29 is movably mounted on the rear side of the transmission wheel 28, and the rotating shaft 29 is movably connected to the inner wall of the blowing sleeve 23. Fan blades 30 are fixedly connected to the front of both the transmission wheel 28 and the drive wheel 26. An air supply duct 32 is fixedly connected to the rear of the two fan blades 30, and the air outlet of the air supply duct 32 is located below the arc-shaped screening screen 19. The rotating shaft 29 on the rear side of the transmission wheel 28 is movably connected to the inner wall of the blowing sleeve 23, providing stable support for the rotation of the transmission wheel 28. When the transmission wheel 28 rotates under the drive of the transmission belt 27, the rotating shaft 29 can reduce the friction during its rotation and ensure smooth rotation. At the same time, the fan blades 30 fixed in front of both the transmission wheel 28 and the drive wheel 26 will rotate synchronously with the rotation of both. During the rotation of the fan blades 30, the air will be disturbed, thereby generating airflow. This airflow is guided in a designated direction through the blowing sleeve 23 to further assist in blowing away the light shell debris generated during the shelling process of Torreya grandis.

[0032] In the existing equipment, most of the shelling operations for Torreya grandis kernels are carried out manually using shelling machinery. This may cause the kernels to break due to excessive force during the shelling process, thereby affecting the product value and reducing its practicality.

[0033] When operating the device, the operator first places the Torreya grandis raw material on the working plate 6, below the pressure plate 5. Then, the electric push rod 3, drive motor 13, and drive motor 24 are activated to put the device into operation. The electric push rod 3 drives drive rod 4 downward, causing the pressure plate 5 to squeeze the Torreya grandis, causing cracks in the outer shell. Then, the operator pushes the push handle 10, and through the sliding of the push plate 9 in the guide groove 8, pushes the initially squeezed Torreya grandis into the interior of the auxiliary shelling component 11. Then, drive motor 13 drives drive rod 21 and rotating rod 14 to rotate, and the crushing plate 15 strikes the Torreya grandis a second time, further crushing the outer shell and separating it from the kernel. The shelled mixture falls into the arc-shaped screening sleeve 18. The arc-shaped screening mesh 19 can separate the Torreya grandis kernels from smaller, lighter debris. As the nuts fall into the collection box 21, the drive motor 24 drives the drive wheel 26 to rotate via the drive rod 3 and the movable rod 25. The transmission belt 27 causes the transmission wheel 28 to rotate synchronously. The fan blades 30 in front of the drive wheel 26 and the transmission wheel 28 generate wind power. The air duct 32 can deliver the wind power generated by the fan blades 30 to the position below the arc-shaped screening screen 19. This allows for accurate air separation of the Torreya nuts and smaller light debris falling from the arc-shaped screening screen 19. The smaller light debris is blown into the impurity box 33, making it easier for operators to process them later. This further improves the purity of the nuts. Finally, the Torreya nuts fall into the collection box 21 below. Operators can use the slider 17 to pull out the arc-shaped screening sleeve 18 to clean up any remaining large impurities and prevent blockages.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
