Description

Technical Field

[0001] The present application relates to the technical field of grain screening, and in particular to a rice screening device for high-nutrition grain processing. Background Art

[0002] The rice sieve device for grain processing is one of the key equipment in grain processing. Its main function is to efficiently classify grains according to particle size through precise physical screening technology, so as to achieve fine processing of grains, improve the efficiency of grain processing, and ensure the quality of the final product to meet the market demand for grain products with different tastes and uses. In practical applications, small grains can be used for specific food processing, such as rice flour or grain beverages, while large grains are more suitable for direct consumption or as cooking ingredients, thereby improving the utilization rate of grains and meeting the taste and nutritional needs of different consumers.

[0003] At present, the rice sieve device mainly includes a frame, a hopper for controlling the speed and amount of grain feeding, a sieve plate located below the hopper outlet for screening with different apertures, and a vibrating component (such as a vibrating motor or an eccentric rotary structure) for driving the sieve plate to vibrate to improve the screening efficiency. During screening, the vibrating component is used to make the sieve plate vibrate at a high frequency, so that the grain particles are evenly distributed on the sieve plate and pass through the sieve holes under the action of gravity. Particles of different sizes are screened according to the size of the sieve plate aperture; however, the rice sieve device can only screen one type of grain. If other types of grains need to be screened, the original sieve plate needs to be removed and replaced with sieve plates of other apertures. However, the sieve plate is fixed with a large number of bolts around it, and its removal and installation are relatively cumbersome. If multiple rice sieve devices are purchased for use, the rice sieve device occupies a large space and has a low space utilization rate. Summary of the invention

[0004] In order to reduce the space requirement for purchasing multiple rice sieve devices, reduce the floor space, improve space utilization, and realize automatic and rapid switching of sieve plates, the present application provides a rice sieve device for high-nutrition grain processing.

[0005] The rice sieve device for high-nutrition grain processing provided in this application adopts the following technical solution: Rice sifting device for high-nutrition grain processing, comprising: A frame, wherein a hopper and an elevator are arranged on the frame; A sieve plate is arranged on a frame and is provided in multiple numbers. The aperture specifications of the multiple sieve plates are different and are arranged in the height direction. Each of the sieve plates is arranged downwardly from the upper hopper to the side away from the upper hopper. Each of the sieve plates is provided with multiple sieve sections along its length direction. The apertures in the multiple sieve sections gradually increase along the sieve plate's downward inclination direction. A collecting hopper is fixedly mounted on the frame and is provided in multiple numbers. The multiple collecting hoppers correspond to the multiple screening sections one by one and are located below the screening sections. A conveyor belt is provided below each of the collecting hoppers; A vibrating device is arranged below the sieve plate, and a plurality of vibrating devices are arranged along the length direction of the sieve plate; The self-switching mechanism is arranged between the frame and the vibration device, and is used to separate or connect the screen plate and the vibration device, and to drive the screen plate to move horizontally and lock the position of the screen plate.

The grains are screened in turn through multiple screening areas along the length direction of the sieve plate to ensure that the same grains of different sizes can be accurately screened. The vibration device promotes the uniform distribution of grain particles on the sieve plate through high-frequency vibration, thereby improving the screening efficiency. Then, the grains of different sizes fall from the corresponding screening areas respectively, enter the collecting hopper below, and enter the conveyor belt from the outlet below the collecting hopper for transportation, thereby realizing the refined processing of the grains. When the sieve plate needs to be replaced to meet the screening needs of different grains, the staff controls the self-switching mechanism to make the sieve plate and the vibration device Separate, then drive the sieve plate to move horizontally to the outside of the screening work area, and move the new sieve plate into the screening work area, then lock the position of the new sieve plate to ensure the stability and safety of the screening process, and then connect the sieve plate to the vibration device again to complete the replacement of the sieve plate to meet the screening needs of different grains; the rice sieve device can not only efficiently classify the grains according to the particle size, realize the refined processing of the grains, meet the market demand for grain products with different tastes, and ensure the quality of the products, but also can quickly replace the sieve plate through the self-switching mechanism, reducing downtime, and at the same time making the rice sieve device able to adapt to the screening needs of various grains, without the need to purchase multiple devices, saving costs and equipment floor space, and improving space utilization.

After the sieve plate is completely moved out, the new sieve plate is connected to the mobile replacement assembly, and the new sieve plate is slid into the screening working area along the guide frame again through the mobile replacement assembly. At the same time, the disassembly and assembly assembly reconnects the sieve plate to the vibration device, and the anti-slip assembly fixes the sieve plate to the frame to ensure the stability and safety of the screening process, thereby completing the rapid replacement of different types of sieve plates; wherein the coordinated cooperation of the disassembly and assembly assembly, the mobile replacement assembly and the anti-slip assembly makes the replacement process of the sieve plate simple and quick, reduces manual intervention, greatly shortens the replacement time of the sieve plate, and reduces the downtime of the rice screening device.

At the same time, multiple anti-dropout rods make the screen plate evenly stressed along its length and not easy to be deformed or damaged. When the screen plate needs to be replaced, the staff starts the lifting cylinder, and drives multiple anti-dropout rods to move up at the same time through the lifting rod, and disengages from the first anti-dropout groove and the second anti-dropout groove, so as to release the fixation of the screen plate, thereby facilitating the subsequent replacement of a new screen plate to the screening working area of ​​the frame.

[0022] Optionally, the end of the baffle away from the rotating shaft is arranged in an arc shape.

[0023] By adopting the above technical solution, when the sieve plate moves into the support groove, one side of the sieve plate will first contact the baffle plate.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0028] The present application embodiment discloses a rice sieve device for high-nutrition grain processing. Figure 1 and Figure 2 The rice screening device includes a frame, and an upper hopper 2 and a bucket elevator 3 are arranged on the frame 1. A plurality of sieve plates 4 are arranged on one side of the frame 1, and the aperture specifications of the plurality of sieve plates 4 are different and arranged in the height direction. Each sieve plate 4 is arranged downwardly from the upper hopper 2 to the side away from the upper hopper 2. And each sieve plate 4 is provided with a plurality of screening zones along its length direction, and the apertures in the plurality of screening zones gradually increase along the downward direction of the sieve plate 4. In order to facilitate subsequent understanding, the frame 1 is divided into a storage area 11 for storing the sieve plates 4 that are not in use, and a screening work area 12 for screening grains on the frame 1. A plurality of collecting hoppers 5 are fixedly arranged on the frame 1, and the plurality of collecting hoppers 5 correspond to the plurality of screening zones one by one and are located below the screening zones; a conveyor belt 6 is arranged at the outlet below each collecting hopper 5. A plurality of vibration devices 7 are also arranged below the sieve plate 4 along its length direction. For example, the vibration device 7 adopts a vibration motor, and other vibration devices 7 such as an eccentric rotary mechanism can also be adopted. A self-switching mechanism 8 is provided between the frame 1 and the vibration device 7 , and the self-switching mechanism 8 is used to separate or connect the sieve plate 4 and the vibration device 7 , and to drive the sieve plate 4 to move laterally and lock the position of the sieve plate 4 .

[0029] When the grains are screened by the rice screen device, the grains are first lifted into the upper hopper 2 by the bucket elevator 3, and then the grains are quantitatively added to the sieve plate 4 by the upper hopper 2. The grains are screened in multiple screening areas in sequence along the length direction of the sieve plate 4 to ensure that the same grains of different sizes can be accurately screened. The vibration device 7 promotes the uniform distribution of grain particles on the sieve plate 4 through high-frequency vibration, improves the screening efficiency, and then the grains of different sizes fall from the corresponding screening areas respectively, enter the collecting hopper 5 below, and enter the conveyor belt 6 from the outlet below the collecting hopper 5 for transportation, thereby realizing the fine processing of the grains.

[0030] When the sieve plate 4 needs to be replaced to meet the screening requirements of different grains, the staff separates the sieve plate 4 from the vibration device 7 by controlling the self-switching mechanism 8. Then the sieve plate 4 is driven to move horizontally to the outside of the screening work area 12, and the new sieve plate 4 is moved into the screening work area 12, and then the position of the new sieve plate 4 is locked to ensure the stability and safety of the screening process. Then the sieve plate 4 is connected to the vibration device 7 again to complete the replacement of the sieve plate 4 to meet the screening requirements of different grains. Among them, the rice sieve device can not only efficiently classify the grains according to the particle size, realize the refined processing of the grains, meet the market demand for grain products with different tastes, and ensure the quality of the products. Moreover, the sieve plate 4 can be quickly replaced by the self-switching mechanism 8 to reduce downtime. At the same time, the rice sieve device can adapt to the screening requirements of various grains without the need to purchase multiple devices, saving costs and equipment floor space, and improving space utilization.

[0031] In some embodiments, reference Figure 2 and Figure 3 The self-switching mechanism 8 includes a plurality of guide rail frames 81 fixedly arranged on one side of the frame 1 along the height direction, and the plurality of guide rail frames 81 correspond to the plurality of sieve plates 4 one by one, and the sieve plates 4 can be located on the corresponding guide rail frames 81 and slide toward or away from the frame 1. A disassembly assembly 82 is arranged between the sieve plates 4 and the frame 1, and the disassembly assembly 82 is used to separate or connect the sieve plates 4 with the vibration device 7. A mobile replacement assembly 83 is arranged between the plurality of sieve plates 4, and the mobile replacement assembly 83 is used to connect the sieve plates 4 and drive the sieve plates 4 to slide on the guide rail frames 81. A plurality of support grooves 13 are provided on the side of the frame 1 away from the guide rail frames 81, and the plurality of support grooves 13 are arranged along the height direction and correspond to the plurality of sieve plates 4 one by one. A rotating shaft 84 is rotatably connected in each support groove 13, and a baffle 85 is fixedly sleeved on the outer side of the rotating shaft 84, and the end of the baffle 85 away from the rotating shaft 84 is arranged in an arc shape. A torsion spring is also provided between the rotating shaft 84 and the frame 1, and the torsion spring continuously applies a torsion force to the baffle 85, so that the baffle 85 blocks the support groove 13, so that the baffle 85 is not easily shaken by vibration and the like to cause material leakage. An anti-slip assembly 86 is provided between the sieve plate 4 and the frame 1, and the anti-slip assembly 86 is used to fix the sieve plate 4 to the frame 1.

[0032] When it is necessary to replace a different type of sieve plate 4, the staff first releases the connection between the sieve plate 4 and the vibration device 7 through the disassembly assembly 82 to prepare for the movement of the sieve plate 4. Then, the locking of the sieve plate 4 by the anti-slip assembly 86 is released, and then the sieve plate 4 is driven to slide along the guide frame 81 to the side away from the frame 1 through the mobile replacement assembly 83 until the sieve plate 4 is completely moved out of the screening work area 12. After the sieve plate 4 is completely moved out, the new sieve plate 4 is connected to the mobile replacement assembly 83, and the new sieve plate 4 is slid into the screening work area 12 along the guide frame 81 through the mobile replacement assembly 83 again, and when the sieve plate 4 is moved from the sieve plate 4 storage area 11 to the screening work area 12 on the frame 1, the movement of the sieve plate 4 will naturally push the baffle 85 to rotate upward around its own rotation axis 84, thereby opening the support slot 13, so that one side of the sieve plate 4 is plugged into the support slot 13, and a certain support is formed for the sieve plate 4. At the same time, the disassembly assembly 82 reconnects the sieve plate 4 to the vibration device 7, and the anti-slip assembly 86 fixes the sieve plate 4 to the frame 1, ensuring the stability and safety of the screening process, and completing the rapid replacement of different types of sieve plates 4. For the sieve plate 4 that is not used temporarily, the baffle 85 will automatically reset to the initial position under the action of the torsion spring, and close the support groove 13 on the frame 1 to prevent leakage. At the same time, through the coordinated cooperation of the disassembly assembly 82, the mobile replacement assembly 83 and the anti-slip assembly 86, the replacement process of the sieve plate 4 becomes simple and fast, reducing manual intervention, greatly shortening the replacement time of the sieve plate 4, and reducing the downtime of the rice sieve device.

At the same time, multiple anti-slip rods 861 make the sieve plate 4 evenly stressed along its length direction, and not easy to deform or damage. When the sieve plate 4 needs to be replaced, the staff starts the lifting cylinder 863, and drives multiple anti-slip rods 861 to move up at the same time through the lifting rod 862, and disengage from the first anti-slip groove 14 and the second anti-slip groove 42, so as to release the fixation of the sieve plate 4, thereby facilitating the subsequent replacement of a new sieve plate 4 to the screening work area 12 of the frame 1.

A bonding groove 41 matching the bonding plate 828 is opened at the bottom of the screen plate 4. The bonding plate 828 can be slidably inserted into the partial bonding groove 41 close to the side of the connecting part 827.

[0036] When the connection between the sieve plate 4 and the vibration device 7 is released by the disassembly assembly 82, the plug-in block 826 is first driven by the driving cylinder 825 to be inserted upward into the plug-in slot 71, and then the connection state of the connection component 827 is released. Then the driving motor 822 is started, the driving motor 822 drives the driving screw 821 to rotate, the driving screw 821 drives the moving block 824 to move along the horizontal direction of the guide rod 823, and the moving block 824 drives the driving cylinder 825, the plug-in block 826, the bonding plate 828 and the vibration device 7 to move, so that the vibration device 7 is separated from the sieve plate 4, and then the driving cylinder 825 drives the vibration device 7 to move downward, and the connection between the sieve plate 4 and the vibration device 7 can be released.

[0037] When the new sieve plate 4 moves to the screening working area 12 of the frame 1, the driving cylinder 825 drives the vibration device 7 to move up to the bottom of the sieve plate 4 again, and drives the moving block 824, the driving cylinder 825, the bonding plate 828 and the vibration device 7 to move horizontally to one side of the connecting component 827 through the driving motor 822, and the connecting component 827 connects the sieve plate 4 with the vibration device 7 again. The position of the vibration device 7 can be moved horizontally and vertically by the disassembly assembly 82, and the installation and disassembly of the vibration device 7 can be automatically and quickly realized by cooperating with the connecting component 827. When the vibration device 7 is connected to the sieve plate 4, the bonding plate 828 slides into the bonding groove 41 at the bottom of the sieve plate 4 to form a close contact surface, ensuring a stable connection between the vibration device 7 and the sieve plate 4. At the same time, the bonding plate 828 also increases the contact area between the vibration device 7 and the sieve plate 4, disperses the vibration force generated by the vibration device 7, and reduces the stress concentration at the connection between the vibration device 7 and the connecting seat 8273, thereby improving the stability and service life of the vibration device 7.

[0038] In some embodiments, reference Figure 5 and Figure 6 , the connecting component 827 includes a connecting rod 8271 fixedly arranged on one side of the vibration device 7, and a connecting block 8272 is fixedly arranged on one end of the connecting rod 8271 away from the vibration device 7. A connecting seat 8273 is fixedly arranged below the sieve plate 4, and a connecting groove is provided on one side of the connecting seat 8273, and the connecting block 8272 can be plugged into the connecting groove. A locking rod 8274 is slidably connected in the vertical direction in the connecting seat 8273, and when the connecting block 8272 is plugged into the connecting groove, the locking rod 8274 abuts against one side of the connecting block 8272 to lock the connecting block 8272 into the connecting groove. A locking spring 8275 is fixedly arranged between the locking rod 8274 and the connecting seat 8273, and the locking spring 8275 is always in a compressed state and gives the locking rod 8274 a force to move toward the connecting groove. An unlocking rod 8276 is also fixedly arranged on the top of the driving cylinder 825, and a long strip-shaped pressing block 8277 is fixedly arranged on the top of the unlocking rod 8276.

[0039] When the vibration device 7 is connected to the bottom of the sieve plate 4, the locking rod 8274 abuts against one side of the connecting block 8272 under the action of the locking spring 8275, so that the connecting block 8272 is locked in the connecting groove of the connecting seat 8273, ensuring the stable connection between the sieve plate 4 and the vibration device 7. When it is necessary to release the connection between the vibration device 7 and the sieve plate 4, the cylinder 825 is first driven to drive the plug-in block 826 and the unlocking rod 8276 to move upward. When the plug-in block 826 is plugged into the plug-in groove 71, the unlocking rod 8276 overcomes the compression force of the locking spring 8275 and applies an upward force to the locking rod 8274, so that the locking rod 8274 drives the pressing block 8277 to release the lock on the connecting block 8272. When the locking rod 8274 is completely moved upward, the connecting block 8272 moves along the connecting groove direction driven by the vibration device 7 and separates from the connecting groove, so that the connection between the sieve plate 4 and the vibration device 7 can be released. By using the locking rod 8274 and the locking spring 8275 in coordination, the connecting block 8272 can be automatically locked into the connecting groove, ensuring a stable connection between the screen plate 4 and the vibration device 7; at the same time, when the top of the driving cylinder 825 moves upward, the unlocking rod 8276 can automatically release the connection between the connecting component 827 and the vibration device 7 and the connecting block 8272, making the unlocking process of the connecting block 8272 simple and quick, reducing manual intervention, and improving the safety and efficiency of the operation.

[0040] In some embodiments, reference Figure 7The mobile replacement assembly 83 includes a lifting frame 831 fixed on the frame 1, and the lifting frame 831 is connected to a lifting screw 832 for rotation in the vertical direction, and a power motor 833 is arranged on the top of the lifting screw 832. A lifting guide rod 834 is fixed on the lifting frame 831, and a lifting block 835 is threadedly connected to the lifting screw 832, and the lifting block 835 is slidably sleeved on the outside of the lifting guide rod 834. A moving cylinder 836 is arranged horizontally on the side of the lifting block 835 close to the frame 1, and an electric clamp 837 is arranged on the side of the moving cylinder 836 close to the frame 1; a pull ring 838 is fixed on one side of the screen plate 4.

[0041] When the sieve plate 4 needs to be replaced, the staff first starts the power motor 833, which drives the lifting screw 832 to rotate, and then the lifting block 835 slides upward along the lifting guide rod 834 until the lifting block 835 drives the moving cylinder 836 to reach the replacement area of ​​the sieve plate 4. Then the moving cylinder 836 is started, and the moving cylinder 836 drives the electric clamp 837 to move to the pull ring 838 position of the sieve plate 4 to be replaced, and then the electric clamp 837 is closed, clamping the pull ring 838 of the sieve plate 4, and dragging the sieve plate 4 horizontally to the sieve plate 4 storage area 11 through the moving cylinder 836, and the electric clamp 837 opens to release the sieve plate 4. Then repeat the above process to replace the new sieve plate 4, but this time the new sieve plate 4 is clamped from the storage area 11 and pushed to the screening work area 12 on the frame 1, and fixed by the anti-slip assembly 86.

[0042] The implementation principle of a rice sieve device for high-nutrition grain processing in the embodiment of the present application is as follows: when the grain is screened by the rice sieve device, the grain is first lifted into the upper hopper 2 by the bucket elevator 3, and then the grain is quantitatively added to the sieve plate 4 through the upper hopper 2, and the grain is screened in turn through multiple screening areas along the length direction of the sieve plate 4 to ensure that the same grains of different sizes can be accurately screened, and the vibration device 7 promotes the uniform distribution of grain particles on the sieve plate 4 through high-frequency vibration to improve the screening efficiency, and then the grains of different sizes fall from the corresponding screening areas respectively, enter the collecting hopper 5 below, and enter the conveyor belt 6 for transportation from the outlet below the collecting hopper 5, thereby realizing the fine processing of the grain; when the sieve plate 4 needs to be replaced to meet the screening needs of different grains, the staff controls the self-switching mechanism 8 Separate the sieve plate 4 from the vibration device 7, then drive the sieve plate 4 to move horizontally to the outside of the screening work area 12, and move the new sieve plate 4 into the screening work area 12, then lock the position of the new sieve plate 4 to ensure the stability and safety of the screening process, and then connect the sieve plate 4 to the vibration device 7 again to complete the replacement of the sieve plate 4 to meet the screening needs of different grains; the rice sieve device can not only efficiently classify the grains according to the particle size, realize the refined processing of the grains, meet the market demand for grain products with different tastes, and ensure the quality of the products, but also can quickly replace the sieve plate 4 through the self-switching mechanism 8, thereby reducing downtime and enabling the rice sieve device to adapt to the screening needs of various grains without the need to purchase multiple devices, thus saving costs and equipment floor space and improving space utilization.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
