Description

Technical Field

[0001] This utility model relates to the field of rice production technology, and in particular to a precision sieving device for rice production. Background Technology

[0002] Rice production refers to the complete industrial chain process from rice planting to processing into rice, involving multiple links and technologies, and is one of the world's most important food production activities.

[0003] Existing precision sieving devices for rice production face numerous problems in practical use. Due to the continuous and high-intensity nature of rice production, the screens are easily clogged by fine impurities such as broken rice and bran powder after prolonged screening. As the clogging intensifies, screening efficiency and accuracy drop significantly. Furthermore, the existing screen design makes disassembly and replacement complex and cumbersome, often requiring multiple tools and a significant amount of time. In some cases, even professional personnel are needed to replace the screens, which not only increases labor costs and maintenance time but also severely impacts the continuity of rice production, causing considerable inconvenience to efficient production operations. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that existing precision sieving devices for rice production have the disadvantage that the sieving effect will decrease due to the clogging of the sieve after long-term use, and the sieve is not easy to disassemble and replace, which brings inconvenience to users. Therefore, we propose a precision sieving device for rice production.

[0005] To achieve the above objectives, this application adopts the following technical solution: a precision sieving device for rice production, comprising a support frame, a driver installed on the top of the support frame, a transmission rod installed at the output end of the driver, a connecting block installed on one side of the transmission rod, a placement plate fixedly connected to one side of the connecting block, a placement groove opened at the bottom of the inner cavity of the placement plate, a through groove opened at the bottom of the inner cavity of the placement groove, a fine sieving plate slidably connected inside the placement groove, insertion grooves opened on both sides of the fine sieving plate, two moving grooves opened at the bottom of the inner cavity of the placement groove, an adjusting block slidably connected inside the moving groove, an insertion block fixedly connected to one side of the adjusting block, and a through slot opened on one side of the inner cavity of the moving groove.

[0006] Preferably, the surface of the plug block has a sliding connection inside the plug groove, and the outer diameter of the plug block is adapted to the inner diameter of the plug groove.

[0007] Preferably, both ends of the inner cavity of the movable groove are provided with sliding grooves, and both ends of the adjusting block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.

[0008] Preferably, a reset spring is fixedly connected to the other side of the adjusting block, and one side of the reset spring is fixedly connected to the other side of the inner cavity of the moving groove.

[0009] Preferably, the bottom of the placement groove is provided with multiple positioning grooves, and multiple positioning blocks are fixedly connected to both sides of the fine sieve plate, with the surface of the positioning block slidingly connected to the inside of the positioning groove.

[0010] Preferably, a circular hole is provided at the bottom of the positioning groove cavity, a thrust spring is fixedly connected to the bottom of the circular hole cavity, and a thrust block is fixedly connected to the top of the thrust spring.

[0011] Preferably, guide grooves are provided on both sides of the inner cavity of the circular hole, and guide blocks are fixedly connected to both sides of the thrust block, with the surface of the guide block slidingly connected to the inside of the guide groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator moves the adjusting block, causing the connecting block to slide inside the moving groove, so that the connecting block disengages from the groove.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-4 As shown, this utility model provides a technical solution: a precision sieving device for rice production, including a support frame 1, a driver 2 installed on the top of the support frame 1, a transmission rod 3 installed at the output end of the driver 2, a connecting block 4 installed on one side of the transmission rod 3, a placement plate 5 fixedly connected to one side of the connecting block 4, a placement groove 7 opened at the bottom of the inner cavity of the placement plate 5, a through groove 6 opened at the bottom of the inner cavity of the placement groove 7, a fine sieving plate 8 slidably connected inside the placement groove 7, insertion grooves 9 opened on both sides of the fine sieving plate 8, and two moving grooves 10 opened at the bottom of the inner cavity of the placement groove 7. An adjusting block 11 is slidably connected inside the groove 10. A plug-in block 12 is fixedly connected to one side of the adjusting block 11. A through slot 13 is opened on one side of the inner cavity of the movable groove 10. By moving the adjusting block 11, the operator can cause the adjusting block 11 to drive the plug-in block 12 to slide inside the movable groove 10, so that the plug-in block 12 is disengaged from the inside of the plug-in slot 9. At this time, the fine sieve plate 8 is unrestrained, and the operator can pull the fine sieve plate 8 out from the inside of the placement groove 7, so that the operator can quickly replace or clean the fine sieve plate 8, which is convenient for screening rice and improves the practicality of the device.

[0022] Reference Figure 3 and Figure 4 As shown in this embodiment: the surface of the plug-in block 12 is internally slidably connected to the plug-in groove 9. The outer diameter of the plug-in block 12 is adapted to the inner diameter of the plug-in groove 9. Through the sliding connection design between the plug-in block 12 and the plug-in groove 9, not only is the rapid installation and disassembly of the fine sieve plate 8 realized, but the stability and reliability of the connection structure are also guaranteed. The outer diameter of the plug-in block 12 is adapted to the inner diameter of the plug-in groove 9, which ensures a tight fit during the plugging process and avoids poor screening effect or equipment failure due to loosening.

[0023] Reference Figure 4 As shown in this embodiment: both ends of the inner cavity of the moving groove 10 are provided with sliding grooves 14, and both ends of the adjusting block 11 are fixedly connected with sliders 15. The surface of the slider 15 is slidably connected to the inside of the sliding groove 14. Through the sliding connection design between the slider 15 and the sliding groove 14, the stability and smoothness of the adjusting block 11 sliding inside the moving groove 10 are further improved, ensuring that the insertion block 12 can be accurately disengaged or inserted from the insertion groove 9, thereby realizing the rapid and stable replacement of the fine screen plate 8.

[0024] Reference Figure 4As shown in this embodiment: a reset spring 16 is fixedly connected to the other side of the adjusting block 11. One side of the reset spring 16 is fixedly connected to the other side of the inner cavity of the moving groove 10. With the reset spring 16, when the adjusting block 11 slides in the moving groove 10, the reset spring 16 can provide a certain elastic restoring force, so that the adjusting block 11 can automatically reset when it is not subjected to external force, thereby ensuring the stable position of the plug-in block 12 in the plug-in groove 9.

[0025] Reference Figure 2 and Figure 3 As shown in this embodiment: multiple positioning grooves 17 are provided at the bottom of the inner cavity of the placement groove 7, and multiple positioning blocks 18 are fixedly connected to both sides of the fine sieve plate 8. The surface of the positioning block 18 is slidably connected to the inside of the positioning groove 17. The cooperation between the positioning block 18 and the positioning groove 17 effectively prevents the fine sieve plate 8 from shaking or shifting during the sieving process, ensuring the accuracy and stability of the sieving results, and further improving the quality of rice sieving.

[0026] Reference Figure 2 and Figure 5 As shown in this embodiment: a circular hole 19 is provided at the bottom of the inner cavity of the positioning groove 17, a thrust spring 20 is fixedly connected to the bottom of the inner cavity of the circular hole 19, and a thrust block 21 is fixedly connected to the top of the thrust spring 20. By setting the circular hole 19, the thrust spring 20 and the thrust block 21, when the fine screen plate 8 is released from fixation, the fine screen plate 8 can be quickly pushed upward a distance, making it more convenient and easier for workers to disassemble and pick up.

[0027] Reference Figure 5 As shown in this embodiment: guide grooves 22 are provided on both sides of the inner cavity of the circular hole 19, and guide blocks 23 are fixedly connected to both sides of the thrust block 21. The surface of the guide block 23 is slidably connected to the inside of the guide groove 22. By setting the guide groove 22 and the guide block 23, the thrust block 21 is limited, making the thrust block 21 more stable when moving and avoiding the phenomenon of displacement or shaking of the thrust block 21 during the movement.

[0028] Working Principle: By moving the adjusting block 11, the operator causes the insertion block 12 to slide inside the moving groove 10, disengaging it from the insertion groove 9. At this point, the fine sieve plate 8 is unrestrained, allowing the operator to pull it out of the placement groove 7. This facilitates quick replacement or cleaning of the fine sieve plate 8, improving the practicality of the device for rice screening. The sliding connection design between the insertion block 12 and the insertion groove 9 not only enables rapid installation and removal of the fine sieve plate 8 but also ensures the stability and reliability of the connection structure. The outer diameter of the insertion block 12 matches the inner diameter of the insertion groove 9, ensuring a tight fit during insertion and preventing poor screening results or equipment malfunctions due to loosening. The sliding connection design between the slider 15 and the slide groove 14 further enhances the stability and smoothness of the adjusting block 11 sliding within the moving groove 10, ensuring that the insertion block 12 can accurately disengage from or insert into the insertion groove 9. This allows for quick and stable replacement of the fine sieve plate 8. The reset spring 16 provides a certain elastic restoring force when the adjusting block 11 slides within the moving groove 10, enabling the adjusting block 11 to automatically reset when not subjected to external force. This ensures the stable position of the insertion block 12 within the insertion groove 9. The cooperation between the positioning block 18 and the positioning groove 17 effectively prevents the fine sieve plate 8 from shaking or shifting during the sieving process, ensuring the accuracy and stability of the sieving results and further improving the quality of rice sieving. The round hole 19, thrust spring 20, and thrust block 21 allow the fine sieve plate 8 to be quickly pushed upwards a certain distance when it is released from its fixed position, making disassembly easier and easier for workers to handle. The guide groove 22 and guide block 23 limit the movement of the thrust block 21, making it more stable and preventing it from shifting or shaking during movement.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
