Description

Technical Field

[0001] This utility model relates to the field of screening structure technology, specifically a nut screening structure. Background Technology

[0002] Currently, screening can remove impurities, foreign objects, incomplete or damaged kernels, ensuring that the quality of the final product meets standards, thereby increasing consumer trust and satisfaction. Screening can remove unwanted shells and impurities in advance, reducing the complexity and difficulty of subsequent processing, improving overall processing efficiency, maximizing the use of available kernel resources, and reducing waste caused by differences in size and quality.

[0003] The existing nut screening structure has a relatively complex working principle, making it difficult to quickly separate nuts and shells. This not only affects production efficiency but also leads to the presence of shells in the product, resulting in a decrease in product quality. In the process of separating nuts and shells, the existing nut screening structure may cause shells and nuts to fall into the shell and not be discharged, which may even affect the mechanical transmission. Therefore, a new nut screening structure is proposed to address the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, by setting two motors to rotate the cam and the fan respectively, the complex structure of the nut sieving structure is simplified. At the same time, the separation effect of nuts and shells is ensured when the mass of the shell is less than that of the nut. By setting elastic telescopic rods and fixing blocks, the sieve plate is supported and elasticity is provided to reduce the wear of the cam.

[0024] Please see Figure 1-6 This utility model provides a technical solution:

[0025] A nut sieving structure includes a shell 1, a transmission rod 4, an elastic telescopic rod 6, a filter screen 10, and a reducer 17. A first motor 2 is fixedly connected to the inside of the shell 1. The reducer 17 is installed at the output end of the first motor 2. The transmission rod 4 is installed at one end of the reducer 17. A cam 5 is fixedly connected to the outside of the transmission rod 4. A sieve plate 11 is provided on one side of the cam 5. A second motor 3 is fixedly connected to the inside of the shell 1. A transmission shaft 8 is fixedly connected to the output end of the second motor 3. A fan device 9 is fixedly connected to one end of the transmission shaft 8.

[0026] A support frame 12 is fixedly connected to the inner side of the housing 1. A drive shaft 8 is installed inside the support frame 12, providing support for the drive shaft 8 and ensuring smooth rotation of the drive shaft 8. An elastic telescopic rod 6 is fixedly connected to the inner side of the housing 1. A fixing block 7 is fixedly connected to the top of the elastic telescopic rod 6. A sieve plate 11 is fixedly connected to one side of the fixing block 7, which supports the sieve plate 11 and uses elasticity to reduce the direct force between the cam 5 and the sieve plate 11, reducing wear on the sieve plate 11. A filter screen 10 is fixedly connected to the inner side of the housing 1, which can protect the filter screen. To ensure unobstructed airflow and prevent contact between nuts and shells and the fan device 9, a rubber plate 16 is fixedly connected to the inner side of the housing 1. A sieve plate 11 is provided on one side of the rubber plate 16 to prevent nuts and shells from falling into the housing 1 through the gap between the sieve plate 11 and the housing 1. A discharge port 13 is provided on the inner side of the housing 1. A first discharge structure 14 is fixedly connected to one side of the housing 1, and a second discharge structure 15 is fixedly connected to one side of the housing 1, so that nuts and shells can be discharged from different positions, facilitating the collection work.

[0027] Working Process: This utility model is equipped with an external controller and a mobile power supply. When we need to perform nut sieving, we use the external controller and mobile power supply to start the first motor 2 and the second motor 3. The rotation of the first motor 2, after being slowed down by the reducer 17, rotates the cam 5 through the transmission rod 4 on one side of the reducer 17. As the cam 5 reaches its highest point, the sieve plate 11 on one side of the cam 5 is continuously raised, and the elastic telescopic rod 6 is stretched through the fixing block 7. Then the cam 5 continues to rotate, and the elastic telescopic rod 6 exerts a downward pulling force on the sieve plate 11 through the fixing block 7, so that the sieve plate 11 can move up and down under the combined action of the cam 5 and the elastic telescopic rod 6. Then the nuts to be sieved are poured onto the sieve plate 11, and the nuts are sieved by the up-and-down movement of the sieve plate. When the shell and kernel are shaken, the rubber plate 16 fixed inside the shell 1 prevents them from falling into the shell 1 through the gap between the sieve plate 11 and the shell 1. At the same time, the second motor 3 rotates the fan device 9 through the transmission shaft 8 set on the support frame 12, so that the fan device 9 can blow the shaken shell to the right until the shell passes through the discharge port 13 and is discharged from the first discharge structure 14. The filter screen 10 inside the shell 1 will ensure that the airflow is not blocked while preventing the kernel and shell from contacting the fan device 9. Finally, the kernel will continue to shake on the sieve plate 11 and approach the lowest point of the sieve plate 11 under the action of gravity until the kernel reaches the lowest point of the sieve plate 11. The lowest point of the sieve plate 11 is in contact with the second discharge structure 15, and then the kernel will be discharged and collected from the second discharge structure 15.
