Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a rice husk separator for rice processing. Background Technology

[0002] In the rice processing industry, rice husk separators are key equipment for separating paddy rice from its husks, and their separation effect directly affects the purity and quality of subsequent rice processing. During the rice husk removal process, a large amount of husk remains after the paddy rice has been dehulled. If not effectively separated, the husks will affect further processing of the rice (such as milling and polishing), reducing the quality of the finished rice. Therefore, rice husk separators are widely used in rice processing plants, grain storage and processing facilities, and are an indispensable piece of equipment in rice processing production lines.

[0003] In actual processing, the physical properties of rice grains and rice husks differ (such as specific gravity and particle size), which provides a basis for separation. Currently, most existing rice husk separators for rice processing use a structure of vibrating motor and a single screen to achieve the separation effect: the vibrating motor drives the screen to vibrate at high frequency, and by utilizing the difference in the motion trajectory of rice grains and rice husks during the vibration process, the rice husks are separated from the screen openings.

[0004] However, in practical applications, the current structure still has room for optimization. First, the frequency of the vibration motor is fixed, which is not flexible enough to adapt to different types and moisture levels of rice. Under some working conditions, the separation efficiency and accuracy are not optimal, and fluctuations in the feed amount can easily affect the separation stability, potentially leaving rice husks behind. Second, the screens are mostly fixed installations, which are inconvenient to disassemble and require machine shutdown for replacement. The operation process needs to be simplified to shorten downtime, reduce labor costs, and improve applicability to various rice specifications. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rice husk separator for rice processing, which aims to improve the problems of low separation efficiency and accuracy caused by the use of vibration motors in traditional rice husk separators for rice sorting, and the separation effect being easily affected by fluctuations in the amount of material fed in.

[0027] Reference Figures 1-4 An embodiment of this utility model is provided: a rice processing husk separator, including a device housing 29, a quick-release assembly inside the device housing 29, and a screening assembly inside the device housing 29;

[0028] The screening assembly includes a fixing block 7, which is disposed inside the equipment housing 29. A connecting seat 2 is fixedly connected to the outer wall of the fixing block 7. A motor 12 is mounted on the outer wall of the fixing block 7. A pull rod 2 6 is fixedly connected to the output end of the motor 12. A pull rod 5 is rotatably connected to one end of the pull rod 2 6. A sliding block 3 is rotatably connected to the inner wall of the pull rod 5. The outer wall of the sliding block 3 is slidably connected to the inner wall of the connecting seat 2. A screen box 1 is fixedly connected to the upper surface of the sliding block 3. A motor 2 4 is mounted on the inner wall of the equipment housing 29. A connecting rod 2 10 is fixedly connected to the output end of the motor 2 4. One end of the connecting rod 2 10 is fixedly connected to the inner wall of the equipment housing 29. A slanted wheel 36 is fixedly connected to the outer wall of the connecting rod 2 10. A connecting block 2 37 is rotatably connected to the inner wall of the slanted wheel 36. A connecting arm 38 is rotatably connected to the outer wall of the connecting block 2 37. A material channel 34 is fixedly connected to one end of the connecting arm 38. The outer wall of the screen box 1 is fixedly connected to the connecting rod 2 10. A connecting rod 11 is fixedly connected to the screen box 1 and the quick-release filter assembly to achieve synchronous movement. The connecting rod 11 is located below the screen 19.

[0029] Specifically, when using this rice husk separator, to separate the rice husks, firstly, the rice to be processed is poured into the feed cylinder 27. At this time, the rice enters the material channel 34 inside the outer shell 29 of the equipment. Motor 2 4 starts and outputs power to drive the connecting rod 2 10 to rotate. The two inclined wheels 36 also start to rotate, driving the connecting block 2 37 and the connecting arm 38 to move up and down. The rice is initially separated on the material channel 34 and enters the screen 19. At this time, motor 1 12 starts and outputs power to drive the pull rod 2 6 and pull rod 1 5 to rotate. The fixing block 7 holds the position of pull rod 2 6. To prevent deviation, the sliding block 3 inside the connecting seat 2 moves horizontally, and the sieve box 1 moves horizontally with the sliding block 3. The sieve assembly moves horizontally with the sieve box 1 via the connecting rod 11 to complete the stratified screening of rice. At this time, the blower 8 starts, the air outlet pipe 9 blows out air, and the exhaust fan 32 starts. Since the weight of rice husks is less than that of brown rice, there is an opening at the bottom of the sieve box 1. The rice husks are blown upward by the wind to the air inlet pipe 28 of the air collection box 30 and collected by the first collection box 31. The rice enters the second collection box 33 through the outlet 35 and is collected. This completes the separation of rice.

A screen 19 is slidably connected to the inner wall of the transverse slide rail 13, and a fixed crossbar is slidably connected to one end of the screen 19. 25. A fixed rod 26 is fixedly connected to the outer wall of the fixed crossbar 25. A tension spring 23 is provided on the inner wall of the fixed rod 26. A connecting block 22 is fixedly connected to one end of the tension spring 23. The other end of the tension spring 23 is fixedly connected to the inner wall of the fixed rod 26. A pull rod 24 is fixedly connected to the lower surface of the connecting block 22. A fixed rod 20 is fixedly connected to one end of the pull rod 24.

The other end of the tension spring 21 is fixedly connected to the inner wall of the fixed crossbar 25.

[0031] Specifically, when the type of rice changes and the screen 19 needs to be replaced, first turn the knob 18 by hand. At this time, the moving block 17 moves upward along the thread of the threaded rod 14. The tension spring 16 on the connecting rod 15 applies an upward force to the moving block 17, removing the moving block 17. Then, grasp the fixing rod 26 and pull it backward. The screen 19 will be pulled out. Press the connecting block 22 downward by hand. The tension spring 23 retracts. The pull rod 24 pulls the fixing rod 20 upward, and the tension spring 21 retracts.

Grasp the fixing rod 26 by hand and insert it into the machine along the transverse slide rail 13. When the insertion is complete, place the moving block 17 on the threaded rod 14 and turn the knob 18. When the moving block 17 abuts against the screen 19, the installation is complete.

[0032] Working principle: When using this rice husk separator, to separate the rice husks, first pour the rice to be processed into the feed cylinder 27. At this time, the rice enters the material channel 34 inside the outer shell 29 of the equipment. Motor 2 4 starts and outputs power to drive the connecting rod 2 10 to rotate. The two inclined wheels 36 also start to rotate, driving the connecting block 2 37 and the connecting arm 38 to move up and down. The rice is initially separated on the material channel 34 and enters the screen 19. At this time, motor 1 12 starts and outputs power to drive the pull rod 2 6 and pull rod 1 5 to rotate. The fixing block 7 holds the position of pull rod 2 6. The fixed position prevents deviation. At this time, the sliding block 3 inside the connecting seat 2 moves horizontally, and the sieve box 1 moves horizontally with the sliding block 3. The screen assembly moves horizontally with the sieve box 1 via the connecting rod 11 to complete the layered screening of rice. At this time, the blower 8 starts, the air outlet pipe 9 blows out air, and the exhaust fan 32 starts. Since the weight of rice husk is less than that of brown rice, there is an opening at the bottom of the sieve box 1. The rice husk is blown upward by the wind to the air inlet pipe 28 of the air collection box 30 and collected by the first collection box 31. The rice enters the second collection box 33 through the outlet 35 and is collected. Thus, the separation of rice is completed.

[0033] When the type of rice changes and the screen 19 needs to be replaced, first turn the knob 18 by hand. At this time, the moving block 17 moves upward along the thread of the threaded rod 14. The tension spring 16 on the connecting rod 15 applies an upward force to the moving block 17, removing the moving block 17. Then, grasp the fixing rod 26 and pull it backward. The screen 19 will be pulled out. Press the connecting block 22 downward by hand. The tension spring 23 retracts. The pull rod 24 pulls the fixing rod 20 upward, and the tension spring 21 retracts. At this time, the screen 19, which is stuck inside the fixing crossbar 25, is removed. When installing the screen 19, press the connecting block 22 and insert the screen into the fixing crossbar 25. Grasp the fixing rod 26 by hand and insert it into the machine along the transverse slide rail 13. When the insertion is complete, place the moving block 17 on the threaded rod 14 and turn the knob 18. When the moving block 17 abuts against the screen 19, the installation is complete.
