Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, and in particular to a drying device for rice processing. Background Technology

[0002] Rice processing equipment refers to a collection of mechanical equipment used to process paddy rice through a series of processes such as cleaning, hulling, milling, and finishing, ultimately producing rice products that meet market standards. Among them, rice processing drying equipment is a collection of mechanical equipment used to remove excess moisture from rice, making it meet the standards for safe storage and processing. Its core function is to achieve efficient drying through heat exchange and airflow circulation, while avoiding quality deterioration.

[0003] Traditional rice drying equipment lacks adjustable scrapers, making it impossible to adjust the thickness of the rice pile on the conveyor belt according to the moisture content of the rice. During the rainy season when the moisture content of the rice is high, the fixed scraper causes the rice layer to be too thick, resulting in a dry exterior and a wet interior. During the dry season or when rice has a low moisture content and has been stored for a long time, the fixed scraper causes the hot air to penetrate too quickly, resulting in rapid evaporation of surface moisture while leaving internal moisture. This increases the rate of broken rice, affects the grade of the finished product and its market price, and requires rework, thus reducing production efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing traditional rice drying equipment lacks an adjustable scraper. To address this, we propose a drying device for rice processing.

[0005] To achieve the above objectives, this application adopts the following technical solution: a drying device for rice processing, comprising a base, a feeding hopper installed on the top of the base, a conveyor belt installed inside the base, a drying device fixedly connected to the top of the base, connecting plates fixedly connected to both sides of the feeding hopper, an adjustment groove opened inside the connecting plate, an adjustment block slidably connected inside the adjustment groove, a scraper installed at the bottom of the adjustment block, irregular grooves opened on both sides of the adjustment block, irregular blocks slidably connected to both ends of the irregular grooves, a square block fixedly connected to one end of the irregular block, two first square grooves opened at both ends of the adjustment block, the surface of the square block slidably connected to the interior of the first square grooves, and second square grooves opened on both sides of the adjustment grooves, the surface of the square block slidably connected to the interior of the second square grooves.

[0006] Preferably, the connecting plate has a first sliding groove on both sides, and two first sliders are fixedly connected to both sides of the adjusting block, with the surface of the first slider slidably connected to the inside of the first sliding groove.

[0007] Preferably, a square plate is fixedly connected inside the irregular groove, and three first springs are fixedly connected to one side of the square plate, with the other end of the first springs fixedly connected to the irregular block.

[0008] Preferably, the top and bottom of the irregularly shaped block are provided with sliding grooves, and sliding blocks are fixedly connected to the top and bottom of both sides of the irregularly shaped groove. The surface of the sliding block is slidably connected to the inside of the sliding groove.

[0009] Preferably, the bottom of the adjusting block is provided with an installation groove, the interior of the installation groove is engaged with the surface of the scraper, two circular grooves are provided on both sides of the scraper surface, a second spring is fixedly connected inside the circular groove, and a snap-fit ​​block is fixedly connected to the other end of the second spring. Two circular holes are provided on both sides of the adjusting block, and the surface of the snap-fit ​​block is slidably connected to the interior of the circular hole.

[0010] Preferably, a limiting piece is fixedly connected to the surface of the snap-fit ​​block, and the surface of the limiting piece is slidably connected to the inside of the circular groove.

[0011] Preferably, a rubber elastic pad is fixedly connected to the bottom of the scraper.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, by pressing the irregularly shaped block, the irregularly shaped block causes the square block to disengage from the inside of the second square groove, thus releasing the limiting position of the adjusting block. At this time, the height of the adjusting block can be adjusted, causing the adjusting block to move the scraper. After adjustment, the pressing of the irregularly shaped block is released, allowing the irregularly shaped block to reset and cause the square block to return to the inside of the second square groove, allowing the adjusting block to re-limit the scraper. When the rice falls from the inside of the equipment base to the top of the conveyor belt, the scraper spreads the rice evenly on the top of the conveyor belt. The rice is then conveyed along the conveyor belt to the inside of the drying equipment for drying. After drying, it is discharged from the end of the equipment base away from the feed hopper. By adjusting the height of the scraper, the thickness of the rice layer on the conveyor belt can be flexibly controlled according to the moisture content and humidity of the rice, significantly enhancing the heat penetration ability in the rice layer and avoiding poor drying effect due to an excessively thick rice layer or scorching due to an excessively thin rice layer. At the same time, the same equipment can flexibly adapt to the processing needs of rice with different particle sizes and shapes without replacing core components or modifying the equipment structure. In this invention, by pressing the locking block, the locking block is moved out of the round hole. At this time, the locking between the locking block and the round hole is canceled, and the scraper can be moved out of the mounting groove. The connection between the adjusting block and the scraper is canceled. When installing the scraper and the adjusting block, the locking block is pressed to make the locking block enter the round groove. Then the scraper is placed into the mounting groove. The pressing of the locking block is released, and the elasticity of the round groove abuts against the locking block, making the locking block enter the round hole and lock with the round hole. This setting allows the scraper to support independent maintenance without stopping the machine to disassemble the entire hopper or conveyor belt, making scraper maintenance more convenient.

[0015] 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.

[0016] Reference Figures 1-4As shown, this utility model provides a technical solution: a drying device for rice processing, including a base 1, a feeding hopper 2 installed on the top of the base 1, a conveyor belt 3 installed inside the base 1, a drying device 4 fixedly connected to the top of the base 1, connecting plates 5 fixedly connected to both sides of the feeding hopper 2, an adjustment groove 6 opened inside the connecting plate 5, an adjustment block 7 slidably connected inside the adjustment groove 6, a scraper 8 installed at the bottom of the adjustment block 7, irregular grooves 9 opened on both sides inside the adjustment block 7, irregular blocks 10 slidably connected to both ends inside the irregular grooves 9, a square block 11 fixedly connected to one end of the irregular block 10, two first square grooves 12 opened at both ends of the adjustment block 7, the surface of the square block 11 slidably connected to the inside of the first square groove 12, and second square grooves 13 opened on both sides of the adjustment groove 6, the surface of the square block 11 slidably connected to the inside of the second square groove 13. By pressing the irregular block 10, the irregular block 10 causes the square block 11 to disengage from the inside of the second square groove 13. The limiting position of the adjusting block 7 can be released, allowing the height of the adjusting block 7 to be adjusted, causing the adjusting block 7 to move the scraper 8. After adjustment, the pressing of the irregular block 10 is released, allowing the irregular block 10 to reset. The irregular block 10 then moves the square block 11 back into the second square groove 13, causing the adjusting block 7 to move the scraper 8 back to its limiting position. When the rice falls from the inside of the equipment base 1 to the top of the conveyor belt 3, the scraper 8 spreads the rice evenly on the top of the conveyor belt 3. The rice is then conveyed along the conveyor belt 3 to the inside of the drying equipment 4 for drying. After drying, the rice is discharged from the end of the equipment base 1 away from the feed hopper 2. By adjusting the height of the scraper 8, the thickness of the rice layer on the conveyor belt 3 can be flexibly controlled according to the moisture content and humidity of the rice, significantly enhancing the heat penetration ability in the rice layer and avoiding poor drying effect due to an excessively thick rice layer or scorching due to an excessively thin rice layer. At the same time, the same equipment can flexibly adapt to the processing needs of rice with different particle sizes and shapes without replacing core components or modifying the equipment structure.

[0017] Reference Figure 3 As shown in this embodiment: the connecting plate 5 has a first slide groove 14 on both sides, and two first sliders 15 are fixedly connected to both sides of the adjusting block 7. The surface of the first slider 15 is slidably connected to the inside of the first slide groove 14. By making the first slider 15 slide inside the first slide groove 14, the adjusting block 7 can be more stable when moving, avoiding unnecessary shaking.

[0018] Reference Figure 4As shown in this embodiment: a square plate 16 is fixedly connected inside the irregular groove 9, and three first springs 17 are fixedly connected to one side of the square plate 16. The other end of the first spring 17 is fixedly connected to the irregular block 10. By setting the first spring 17, the elasticity of the first spring 17 abuts against the irregular block 10. When the user releases the press on the irregular block 10, the elasticity of the first spring 17 can abut against the irregular block 10, so that the irregular block 10 automatically resets without the need for manual reset by the user, simplifying the operation process.

[0019] Reference Figure 4 As shown in this embodiment: the top and bottom of the irregular block 10 are provided with sliding grooves 18, and the top and bottom of both sides of the irregular groove 9 are fixedly connected with sliding blocks 19. The surface of the sliding block 19 is slidably connected to the inside of the sliding groove 18. By making the sliding block 19 slide inside the sliding groove 18, the movement of the irregular block 10 can be more guided, avoiding unnecessary deviation when the irregular block 10 moves inside the irregular groove 9, so that the irregular block 10 drives the square block 11 to accurately enter the inside of the second square groove 13.

[0020] Reference Figure 5 As shown in this embodiment: the bottom of the adjusting block 7 is provided with a mounting groove 20, the interior of the mounting groove 20 is engaged with the surface of the scraper 8, two circular grooves 21 are provided on both sides of the surface of the scraper 8, a second spring 22 is fixedly connected inside the circular groove 21, and a locking block 23 is fixedly connected to the other end of the second spring 22. Two circular holes 24 are provided on both sides of the adjusting block 7, the surface of the locking block 23 is slidably connected with the interior of the circular hole 24, and by pressing the locking block 23, the locking block 23 is moved out of the interior of the circular hole 24, at which time the locking block 23 and the circular hole 24 are engaged. Cancellation allows the scraper 8 to be removed from the mounting slot 20, canceling the connection between the adjusting block 7 and the scraper 8. When installing the scraper 8 and the adjusting block 7, press the locking block 23 to allow the locking block 23 to enter the circular groove 21. Then, place the scraper 8 into the mounting slot 20 and release the pressing of the locking block 23. The elasticity of the circular groove 21 abuts against the locking block 23, allowing the locking block 23 to enter the circular hole 24 and engage with it. This setting allows the scraper 8 to support independent maintenance without stopping the machine to disassemble the entire hopper or conveyor belt 3, making the maintenance of the scraper 8 more convenient.

[0021] Reference Figure 5 As shown in this embodiment: the surface of the snap-fit ​​block 23 is fixedly connected to the limiting piece 25, and the surface of the limiting piece 25 is slidably connected to the inside of the circular groove 21. By setting the limiting piece 25, the movement position of the snap-fit ​​block 23 can be effectively restricted, preventing one end of the snap-fit ​​block 23 from coming out of the inside of the circular groove 21 due to the excessive elasticity of the second spring 22, thus ensuring the stability of the snap-fit ​​between the snap-fit ​​block 23 and the circular hole 24.

[0022] Reference Figure 5As shown in this embodiment: a rubber elastic pad 26 is fixedly connected to the bottom of the scraper 8. By setting a limiting piece 25, the limiting piece 25 can absorb the impact force of rice grains, prevent the local rice layer from being over-compacted due to rigid contact, and ensure the air permeability of the rice layer. At the same time, the rubber elastic pad 26 replaces the traditional metal scraper 8 to directly contact the rice. It absorbs the impact force between the rice grains and the scraper 8 through elastic deformation, avoiding the generation of broken rice caused by mechanical squeezing.

[0023] Working principle: By pressing the irregularly shaped block 10, the irregularly shaped block 10 drives the square block 11 out of the second square groove 13, releasing the limiting position of the adjusting block 7. At this time, the height position of the adjusting block 7 can be adjusted, causing the adjusting block 7 to move the scraper 8. After adjustment, releasing the pressing of the irregularly shaped block 10 resets it, and the irregularly shaped block 10 drives the square block 11 back into the second square groove 13, causing the adjusting block 7 to move the scraper 8 back to its limiting position. When the rice falls from the inside of the equipment base 1 to the top of the conveyor belt 3, the scraper 8 evenly spreads the rice on the top of the conveyor belt 3. Then, the rice is conveyed along the conveyor belt 3 to the inside of the drying equipment 4 for drying. After drying, it is discharged from the end of the equipment base 1 away from the feed hopper 2. By adjusting the height of the scraper 8, the thickness of the rice layer on the conveyor belt 3 can be flexibly controlled according to the moisture content and humidity of the rice. This significantly enhances the heat penetration within the rice layer, preventing poor drying due to an excessively thick layer or scorching due to an excessively thin layer. Furthermore, the same equipment can flexibly adapt to the processing needs of rice with different particle sizes and shapes without requiring replacement of core components or modification of the equipment structure. By allowing the first slider 15 to slide inside the first groove 14, the adjusting block 7 can be made more stable during movement, avoiding unnecessary shaking. A first spring 17 is provided; its elasticity abuts against the shaped block 10. When the user releases the pressure on the shaped block 10, the elasticity of the first spring 17 allows the shaped block 10 to automatically reset. No manual reset is required, simplifying the operation process. By allowing the sliding block 19 to slide inside the sliding groove 18, the movement of the irregular block 10 becomes more guided, preventing unnecessary offset when the irregular block 10 moves inside the irregular groove 9. This allows the irregular block 10 to accurately drive the square block 11 into the second square groove 13. By pressing the locking block 23, the locking block 23 is removed from the inside of the round hole 24. At this time, the locking between the locking block 23 and the round hole 24 is canceled, and the scraper 8 can be removed from the inside of the mounting groove 20. The connection between the adjusting block 7 and the scraper 8 is canceled. When installing the scraper 8 and the adjusting block 7, pressing the locking block 23 allows the locking block 23 to enter the inside of the round groove 21. Then, the scraper 8 is placed into the inside of the mounting groove 20, and the locking block 23 is released. When the circular groove 21 moves, the elasticity of the circular groove 21 abuts against the locking block 23, causing the locking block 23 to enter the interior of the circular hole 24 and engage with it. This design allows the scraper 8 to be maintained independently without stopping the machine to disassemble the entire hopper or conveyor belt 3, making scraper 8 maintenance more convenient. The limiting piece 25 effectively restricts the movement of the locking block 23, preventing one end of the locking block 23 from detaching from the interior of the circular groove 21 due to excessive elasticity of the second spring 22, ensuring the stability of the engagement between the locking block 23 and the circular hole 24. The limiting piece 25 can also absorb the impact force of rice grains, preventing excessive compaction of the rice layer due to rigid contact and ensuring the air permeability of the rice layer. At the same time, the rubber elastic pad 26 replaces the traditional metal scraper 8 in direct contact with the rice.By absorbing the impact force between the rice grains and the scraper 8 through elastic deformation, the broken rice caused by mechanical compression is avoided.
