Description

Technical Field

[0001] This invention relates to the field of nut processing technology, specifically a rotary nut flat-rolling shelling machine. Background Technology

[0002] Nut shelling is a crucial step in nut processing. Existing drum-type nut shelling machines use an inner rotating scraper drum to squeeze and rub the nuts between the drum and the outer semi-circular concave screen to remove their shells. However, this shelling method has obvious drawbacks. The outer semi-circular concave screen is a static structure, making it difficult for the nut particles to quickly leave the shelling space. They are repeatedly squeezed and rubbed. For nuts with hard shells, excessive friction can easily lead to kernel breakage. For example, the breakage rate is too high when processing walnuts and pecans. If the nut shells have cracks or curvature, the breakage rate will be even higher. Furthermore, the shell-kernel mixture cannot be discharged in time due to the blockage of the screen holes, which will aggravate secondary squeezing and form a vicious cycle of breakage. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a rotary nut flat-rolling shelling machine, which has the advantages of strong adaptability to grading and shelling, and solves the problem of high nut breakage rate caused by repeated squeezing in traditional roller shelling machines.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A rotary nut flat-rubbing and shelling machine includes a frame, which is a cuboid structure. A gap adjustment frame is fixedly connected to the inner side of the frame via corner pieces. A fixed scraping device is connected to the gap adjustment frame. A rubbing plate is set below the fixed scraping device. The rubbing plate is divided into inner and outer rings with different openings. A drive disc is set below the rubbing plate. A drive device is connected to the drive disc. The drive device drives the drive disc via a synchronous belt. A discharge device is set below the drive disc.

[0005] Preferably, the rubbing plate can rotate under the drive of the drive disc, and the rubbing plate and the fixed scraping device cooperate to form a squeezing structure for crushing nut shells.

[0006] Preferably, the discharge device is used to discharge nut kernels, shells, and small, incompletely shelled nuts after the outer shell has been removed.

[0007] Preferably, it also includes a scraper roller, which is disposed at the fixed scraper device.

[0008] Preferably, the inner ring of the washboard is fitted with an inner ring wash roller, and the outer ring of the washboard is fitted with an outer ring wash roller.

[0009] Preferably, the rice separator on the frame is connected to a dust removal device.

[0010] Preferably, a feeding device is provided on the outside of the frame, and the feeding device is provided with two guide hoppers.

[0011] By employing the above technical solution, the present invention provides a rotary nut flat-rolling shelling machine, which has at least the following beneficial effects: 1. This rotary nut flat rubbing and shelling machine divides the rubbing plate into inner and outer rings with different opening sizes. The outer ring has a smaller opening for processing small and re-shelling nuts, while the inner ring has a larger opening for processing large nuts. With the help of the feeding device, the inner and outer rings of the rubbing plate are connected respectively, realizing the graded shelling of nuts of different sizes.

[0012] 2. This rotary nut flat-rubbing shelling machine, through the flat-rubbing design and the suppressive design of the scraper roller, allows the shelled nuts to smoothly enter the discharge device, preventing repeated squeezing and greatly reducing the breakage rate.

[0013] 3. This rotary nut flat rubbing shelling machine can flexibly adjust the squeezing force according to the nut variety and shell hardness, avoiding excessive squeezing that could damage the kernels. Combined with the flat rubbing design rather than the traditional roller-type throwing and squeezing, the shelled nut kernels can smoothly enter the discharge device 7 with the inclined guide plate structure below along the rubbing plate arc, effectively preventing repeated squeezing and greatly reducing the breakage rate.

[0014] 4. This rotary nut flat rubbing and shelling machine can change the gap between the scraper roller and the rubbing plate by rotating the adjusting screw. This ensures the parallelism between the scraper roller and the rubbing plate during the adjustment process, avoids excessive or insufficient local squeezing caused by tilting, ensures uniform shelling effect, and reduces nut breakage rate.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The rotary nut flat-rolling shelling machine provided by some embodiments of the present invention is described below with reference to the accompanying drawings.

[0019] Example 1: Existing drum-type shelling machines often lack a clear grading and feeding structure, resulting in the mixing and shelling of nuts of different sizes. This leads to incomplete shelling of small nuts and easy breakage of large nuts, as well as low drive transmission efficiency. To solve these problems, a new method is proposed, combining... Figures 1-3 As shown, the rotary nut flat-rubbing shelling machine provided by the present invention includes a frame 1 with a cuboid structure. A gap adjustment frame 2 is fixedly connected to the inner side of the frame 1 through corner pieces. A fixed scraping device 3 is connected to the gap adjustment frame 2. The fixed scraping device 3 is provided with inner and outer ring feeding channels. Below it is a rubbing plate 4 divided into inner and outer rings with different openings. A drive disk 5 is provided below the rubbing plate 4. A drive device 6 connected to the drive disk 5 is installed on the frame 1. The drive device 6 drives the drive disk 5 to rotate through a synchronous belt, thereby driving the rubbing plate 4 to rotate. A discharge device 7 is provided below the drive disk 5. A feeding device 12 is provided on the outer side of the frame 1. The feeding device 12 is provided with two guide hoppers 13 that are respectively connected to the inner and outer ring feeding channels of the fixed scraping device 3. The graded nuts are fed into the inner and outer rings of the fixed scraping device 3 through the two guide hoppers 13. With the help of the rubbing plates 4 with different openings in the inner and outer rings, the targeted shelling of nuts of different sizes can be achieved.

[0020] Specifically, the outer ring opening size of the rubbing board 4 is smaller than the inner ring opening size. The two guide hoppers 13 of the feeding device 12 are connected to the outer ring feeding channel of the fixed scraping device 3 to transport small nut particles, and the other is connected to the inner ring feeding channel to transport large nut particles.

[0021] As can be seen from the embodiments, the combination of graded feeding and graded swirl plate 4 avoids the drawbacks of mixing and shelling nuts of different sizes. Simultaneously, the drive device 6 drives the drive disc 5 via a synchronous belt, ensuring stable and efficient transmission. The shelled material can fall directly into the discharge device 7 below, reducing unnecessary conveying losses. Embodiment Two: In existing shelling machines, some nuts tend to adhere to the surface of the scraper during the shelling process, leading to accumulation. Furthermore, dust mixed in with the shelled material cannot be removed promptly, affecting the quality of the nuts. To address these issues, a new method is developed that combines... Figure 2 and Figure 3As shown, based on Embodiment 1, a scraper roller 8 is provided at the fixed scraper device 3. The scraper roller 8 has a downward rotating structure, which naturally makes it less likely for material to accumulate.

[0022] Specifically, the scraper roller 8 adopts a cylindrical structure to prevent material breakage. The nut kernels and shells that have been removed, as well as the small nut kernels that have not been completely removed, enter the kernel separator below through the discharge device 7. Dust and shells are sucked away, and kernels are produced. The small kernels are sent back to the outer ring for re-removal.

[0023] The frame 1 and the gap adjustment frame 2, and the fixed scraping device 3 and the gap adjustment frame 2 are all connected by a quick-release structure 11. The quick-release structure 11 includes a buckle and a limit pin, which ensures the stability of the gap adjustment frame when it is running at high speed, prevents the fixed scraping device 3 from shifting or falling off due to connection failure, and improves the safety of equipment operation.

[0024] As can be seen from the embodiments, the scraper roller 8 solves the problem of easy material breakage, and the fruit and rice separator realizes the functions of dust removal, separation of fruit shells, separation of fruit grains, and separation of small nut particles. Example 3: The existing shelling machine's rubbing plate 4 and scraping device have difficulty adapting the squeezing force to nuts of different hardness, and the rubbing effect of the rubbing plate 4 is limited, resulting in poor shelling adaptability. To solve the above problems, combined with... Figure 1 and Figure 2 As shown, based on Embodiment 1, the inner ring of the rubbing board 4 is fitted with an inner ring rubbing roller 9, and the outer ring of the rubbing board 4 is fitted with an outer ring rubbing roller 10. The inner ring rubbing roller 9 and the outer ring rubbing roller 10 are respectively adapted to the opening structure of the inner and outer rings of the rubbing board 4, thereby enhancing the rubbing and squeezing effect of the rubbing board 4 on the nuts. At the same time, the gap adjustment frame 2 can change the gap between the fixed scraping device 3 and the rubbing board 4 by adjusting the structure. When processing nuts with harder shells, the gap is reduced to increase the squeezing force, and when processing nuts with softer shells, the gap is increased to avoid damage to the kernels.

[0025] Specifically, the inner ring rubbing roller 9 has the same diameter as the outer ring rubbing roller 10, and both are connected to the frame 1 through bearings, and can rotate synchronously with the rotation of the rubbing plate 4; the gap adjustment frame 2 is equipped with an adjustment bolt, and by turning the adjustment bolt, the fixed scraping device 3 can be moved in the vertical direction, thereby changing its gap with the rubbing plate 4.

[0026] As can be seen from the embodiments, the setting of the inner ring rubbing roller 9 and the outer ring rubbing roller 10 enhances the rubbing and shelling effect and improves the shelling rate. The adjustable design of the gap adjustment frame 2 allows the equipment to adapt to nuts of different hardness such as walnuts, almonds, and macadamia nuts, greatly improving the shelling adaptability and flexibility of the equipment.

[0027] As can be seen from the above embodiments: the graded nuts enter the inner and outer rings of the fixed scraper device 3 through the two guide hoppers 13 on the outer feeding device 12 of the frame 1. After the drive device 6 is started, the drive device 6 drives the drive disc 5 to rotate through the synchronous belt. The drive disc 5 then drives the rubbing plate 4 above it to rotate. The rotating rubbing plate 4 cooperates with the fixed scraper device 3 to push the nuts between them to squeeze each other, thereby breaking the nut shells and achieving nut shelling. The nut kernels, shells, and smaller unshelled nuts are then crushed by gravity. The material falls to the discharge device 7 below the drive disk 5 under the action of the discharge device 7. During the operation of the discharge device 7, the dust removal device 14 operates simultaneously to remove some dust and impurities in the material. After the material is discharged from the discharge device 7, it enters the subsequent fruit and rice separator equipment. The fruit and rice separator removes light impurities (such as fine shells) in the material by the difference in specific gravity. After being screened by the fruit and rice separator, qualified nut kernels enter the next processing step, while the small nut kernels that are not completely shelled are transported back to the outer ring of the fixed scraping device 3 by the lifting device to participate in the shelling operation again, forming a cyclic shelling process.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
