Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a rice hulling and fine screening device for rice processing. Background Technology

[0002] Rice processing refers to the process of turning paddy rice into edible rice through a series of processes such as cleaning, hulling, milling, polishing, and screening. The paddy hulling and screening device is a special equipment used in rice processing to remove the outer shell of paddy rice and screen out qualified brown rice. It is usually composed of a hulling unit and a screening unit.

[0003] In existing rice dehulling and screening devices, the feeding speed of rice generally depends on the feed rate and the inertia of the rice, and cannot be actively controlled. This makes it easy for rice to clog and accumulate inside the device, thus affecting the screening efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the feeding speed of rice in the prior art cannot be controlled, which will cause blockage and accumulation. To address this, we propose a rice hulling and fine screening device for rice processing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rice hulling and fine screening device for rice processing, comprising a device shell: a top cover is installed at the top of the device shell, a vibration component is installed at the front end of the device shell, a feed pipe and a fixing block are installed at the top of the top cover, a discharge pipe is installed at the bottom end of the device shell, an adjustment groove is provided on one side of the feed pipe, a flow limiting plate is slidably connected inside the adjustment groove, an adjustment rod is slidably connected inside the fixing block, a handle is fixedly connected to one side of the adjustment rod, the side of the adjustment rod near the flow limiting plate is fixedly connected to the flow limiting plate, multiple limiting grooves are provided at both the front and rear ends of the adjustment rod, sliding grooves are provided at both the front and rear ends of the fixing block, a sliding rod is slidably connected inside the sliding groove, a push-pull plate is fixedly connected to the end of the sliding rod away from the fixing block, a spring is sleeved on the surface of the sliding rod, and the two ends of the spring are fixedly connected to the fixing block and the push-pull plate respectively.

[0006] Preferably, the top and bottom of the fixed block are provided with guide grooves, the top and bottom of the adjusting rod are fixedly connected with guide blocks, and the inside of the guide groove is slidably connected to the guide block.

[0007] Preferably, two energy storage springs are fixedly connected to the side of the handle near the fixing block, and the side of the energy storage springs away from the handle is fixedly connected to the fixing block.

[0008] Preferably, a stop groove is provided on both sides of the sliding groove, and a stop block is fixedly connected to both sides of the sliding rod, and the inside of the stop groove is slidably connected to the stop block.

[0009] Preferably, the surface of the flow restrictor is provided with an inclined surface, and the surface of the flow restrictor is coated with an epoxy resin coating.

[0010] Preferably, the inner diameter of the limiting groove is designed to match the size of the sliding rod.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, when the worker needs to control the feeding speed of the rice, the push-pull plate is pulled outward to pull the sliding rod out of the limiting groove, thus releasing the fixing of the adjusting rod. The adjusting rod is then moved to move the flow-limiting plate to a suitable position for rice feeding. The sliding rod is then aligned with the limiting groove, releasing the stored elastic force of the spring and causing the sliding rod to quickly insert into the limiting groove, thereby achieving stable fixing of the flow-limiting plate after adjustment. This design allows for convenient control of the rice feeding speed, enabling flexible adjustment of the feeding speed according to actual needs as the rice enters the device through the feed pipe. When the rice falls at a suitable speed, it effectively reduces the accumulation and blockage of rice within the device, improving screening efficiency. Attached Figure Description

[0014] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0015] Reference Figures 1-4 As shown, this utility model provides a technical solution: a rice hulling and fine screening device for rice processing, including a device shell 1; a top cover 2 is installed at the top of the device shell 1, a vibration component 3 is installed at the front end of the device shell 1, a feed pipe 4 and a fixing block 5 are installed at the top of the top cover 2, and a discharge pipe 21 is installed at the bottom end of the device shell 1. An adjustment groove 6 is opened on one side of the feed pipe 4, a flow limiting plate 7 is slidably connected inside the adjustment groove 6, an adjustment rod 8 is slidably connected inside the fixing block 5, a handle 9 is fixedly connected to one side of the adjustment rod 8, the side of the adjustment rod 8 near the flow limiting plate 7 is fixedly connected to the flow limiting plate 7, multiple limiting grooves 10 are opened at both the front and rear ends of the adjustment rod 8, sliding grooves 11 are opened at both the front and rear ends of the fixing block 5, a sliding rod 12 is slidably connected inside the sliding groove 11, a push-pull plate 13 is fixedly connected to the end of the sliding rod 12 away from the fixing block 5, and a spring is sleeved on the surface of the sliding rod 12. The force spring 14 is fixedly connected at both ends to the fixed block 5 and the push-pull plate 13, respectively. When the operator needs to control the feeding speed of the rice, the push-pull plate 13 is pulled outward to pull the sliding rod 12 out of the limiting groove 10, so that the adjusting rod 8 is released. Then, the adjusting rod 8 is moved to move the flow limiting plate 7 to a suitable position for rice feeding. Then, the sliding rod 12 is aligned with the limiting groove 10. At this time, the elastic force stored in the force spring 14 is released, which drives the sliding rod 12 to quickly insert into the limiting groove 10, thereby achieving stable fixation of the flow limiting plate 7 after position adjustment. By setting the rice feeding speed for convenient control, the feeding speed of the rice can be flexibly adjusted according to actual needs when the rice enters the device through the feed pipe 4. When the rice falls at a suitable speed, it can effectively reduce the accumulation and blockage of rice in the device and improve the screening efficiency.

[0016] Reference Figure 4As shown in this embodiment: guide grooves 15 are provided at both the top and bottom of the fixed block 5, and guide blocks 16 are fixedly connected to both the top and bottom of the adjusting rod 8. The interior of the guide groove 15 is slidably connected to the guide block 16. Through the setting of the guide groove 15 and the guide block 16, the adjusting rod 8 can form a stable guiding effect when sliding inside the fixed block 5, so that the adjusting rod 8 will not deviate in position when driving the flow limiting plate 7 to adjust its position, thereby effectively improving the accuracy of adjustment.

[0017] Reference Figure 5 As shown in this embodiment: two energy storage springs 17 are fixedly connected to the side of the handle 9 near the fixing block 5, and the side of the energy storage spring 17 away from the handle 9 is fixedly connected to the fixing block 5. With the setting of the energy storage spring 17, when the rice is fed, the adjusting rod 8 is released from the fixing. At this time, the elastic force stored in the energy storage spring 17 is released, which drives the flow limiting plate 7 to spring back to the initial adjustment position, thereby achieving the quick reset of the flow limiting plate 7 after use, which is convenient for the next use.

[0018] Reference Figure 5 As shown in this embodiment: both sides of the sliding groove 11 are provided with stop grooves 18, and both sides of the sliding rod 12 are fixedly connected with stop blocks 19. The inside of the stop groove 18 is slidably connected with the stop block 19. Through the setting of the stop groove 18 and the stop block 19, the sliding rod 12 can form a stable limit during the sliding process, so that the sliding rod 12 will not slide excessively when sliding inside the sliding groove 11, effectively improving the stability of the flow limiting plate 7 and the adjusting rod 8 during the fixing process.

[0019] Reference Figure 3 As shown in this embodiment: the surface of the flow limiting plate 7 is provided with an inclined surface 20, and the surface of the flow limiting plate 7 is coated with an epoxy resin coating. By setting the inclined surface 20 and the epoxy resin coating, the rice grains will not stick during the feeding process, and the overall feeding process is more efficient, thereby effectively improving the screening efficiency.

[0020] Reference Figure 3 and Figure 4 As shown in this embodiment, the inner diameter of the limiting groove 10 is designed to match the size of the sliding rod 12. By matching the size of the limiting groove 10 with that of the sliding rod 12, the flow limiting plate 7 will not shake or shift during the fixing process, thereby effectively improving the stability of the flow limiting plate 7 after the position is adjusted.

[0021] Working Principle: When the operator needs to control the feeding speed of rice, the push-pull plate 13 is pulled outward, causing the sliding rod 12 to be pulled out from the inside of the limiting groove 10, thus releasing the fixing of the adjusting rod 8. At this time, the adjusting rod 8 is moved to move the flow limiting plate 7 to a suitable position for rice feeding. Then, the sliding rod 12 is aligned with the limiting groove 10. At this time, the elastic force stored in the spring 14 is released, causing the sliding rod 12 to quickly insert into the limiting groove 10, thereby achieving stable fixing of the flow limiting plate 7 after position adjustment. By setting the rice feeding speed for convenient control, the feeding speed of rice can be flexibly adjusted according to actual needs when entering the device through the feed pipe 4. When the rice falls at an appropriate speed, it can effectively reduce the accumulation and blockage of rice in the device, improving the screening efficiency. Through the setting of the guide groove 15 and the guide block 16, the adjusting rod 8 can form a stable guiding effect when sliding inside the fixed block 5, thus preventing the adjusting rod 8 from shifting position when adjusting the position of the flow limiting plate 7. The offset is effectively improved, thus enhancing the accuracy of adjustment. With the setting of the energy storage spring 17, after the rice is fed, the adjusting rod 8 is released. At this time, the elastic force stored in the energy storage spring 17 is released, causing the flow limiting plate 7 to spring back to the initial adjustment position, thereby achieving quick reset of the flow limiting plate 7 after use, which is convenient for the next use. With the setting of the stop groove 18 and the stop block 19, the sliding rod 12 can form a stable limit during the sliding process, thus preventing the sliding rod 12 from sliding excessively when sliding inside the sliding groove 11, effectively improving the stability of the flow limiting plate 7 and the adjusting rod 8 during the fixing process. With the setting of the inclined surface 20 and the epoxy resin coating, the rice will not stick during the feeding process, and the overall feeding process is more efficient, thus effectively improving the screening efficiency. With the setting of the limiting groove 10 and the sliding rod 12 matching the size, the flow limiting plate 7 will not shake or shift during the fixing process, thus effectively improving the stability of the flow limiting plate 7 after the position adjustment.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
