Abstract
Description
Technical Field
[0001] This utility model relates to the field of brown rice processing technology, and in particular to a brown rice processing device based on flexible dehulling technology. Background Technology
[0002] With the improvement of people's living standards and the enhancement of health awareness, brown rice, as a whole grain food rich in dietary fiber, vitamins, and minerals, is increasingly favored by consumers. Brown rice processing is an important link in the rice industry chain, and its processing quality directly affects the nutritional value, taste, and market competitiveness of brown rice. However, traditional brown rice processing equipment has many problems in the processing process, which restricts the development of the brown rice industry.
[0003] 1. In the feeding stage of brown rice processing, most existing processing equipment lacks an effective feeding control mechanism, and rice often enters the processing system in excessive amounts at one time. This excessive feeding leads to uneven load on subsequent processes such as hulling and screening, thereby affecting the stability of the processing.
[0004] 2. In the hulling process, traditional mechanical hulling methods mainly rely on rigid components to squeeze and rub the rice to achieve the purpose of hulling. However, this rigid hulling method has obvious drawbacks. Because the contact between the rigid components and the rice is relatively harsh, it is easy to cause mechanical damage to the brown rice during the hulling process, resulting in a high rate of broken rice.
[0005] 3. The lack of a structure for screening brown rice results in a certain proportion of broken rice mixed in with the output brown rice, affecting the quality and purity of the brown rice and failing to meet the market demand for high-quality brown rice.
[0006] Therefore, it is now necessary to design a brown rice processing device based on flexible dehulling technology. Utility Model Content
[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a brown rice processing device based on flexible dehulling technology.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A brown rice processing device based on flexible dehulling technology includes a casing, a feeding hopper connected to the upper end of the casing, a feeding mechanism located below the feeding hopper inside the casing, a dehulling mechanism located below the feeding mechanism inside the casing, a screening mechanism located below the dehulling mechanism inside the casing, a movable groove provided on the side wall of the casing, the screening mechanism located inside the movable groove, a blower fan installed on one side wall of the casing, and a waste discharge pipe connected to the other side wall of the casing.
[0010] As a further improvement of this utility model, the fabric feeding mechanism includes a second rotating shaft disposed inside the housing. One end of the second rotating shaft is rotatably connected to the inner wall of the housing, and the other end of the second rotating shaft passes through the inner wall of the housing and extends to the outside of the housing. A rotating column is fixedly sleeved on the side wall of the second rotating shaft inside the housing, and a plurality of material storage grooves are uniformly arranged along the circumference of the side wall of the rotating column.
[0011] As a further improvement of this utility model, the shell-removing mechanism includes two first rotating shafts disposed inside the housing. One end of the first rotating shaft is rotatably connected to the inner wall of the housing, and the other end of the first rotating shaft passes through the inner wall of the housing and extends to the outside of the housing. Flexible rubber rollers are fixedly sleeved on the side walls of the two first rotating shafts located inside the housing, and gears are fixedly sleeved on the side walls of the two first rotating shafts located outside the housing. The two gears mesh.
[0012] As a further improvement of this utility model, the screening mechanism includes a screen frame disposed inside the housing. The screen frame is inclined and extends into a movable groove. Two fixed plates are disposed below the screen frame. The two fixed plates are respectively fixedly connected to the inner walls of opposite sides of the housing. Two connecting plates are fixed to the lower end of the screen frame. Two guide rods are fixed between the two connecting plates. The two guide rods pass through the two fixed plates and are slidably connected to the fixed plates. Two springs are sleeved on the guide rods. The two springs are respectively disposed on both sides of the fixed plates. A linear vibration motor is installed at the lower end of the screen frame.
[0013] As a further improvement of this utility model, a fixing frame is fixed on the outer wall of the housing, and a motor is installed on the fixing frame. The output shaft of the motor passes through the fixing frame and is fixed to the end of the second rotating shaft.
[0014] As a further improvement of this utility model, a second synchronous pulley is fixedly sleeved on the side wall of the second rotating shaft, and a first synchronous pulley is fixedly sleeved on the side wall of one of the first rotating shafts. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt drive.
[0015] As a further improvement of this utility model, guide plates are provided above both of the flexible rubber rollers, and the guide plates are fixedly connected to the inner wall of the machine housing.
[0016] As a further improvement of this utility model, a pull-out groove is provided on the side wall of the housing, and a collection box is provided inside the pull-out groove.

The connecting bolts are screwed onto the side walls of the discharge pipe.
[0018] As a further improvement of this utility model, a handle is fixed on the side wall of the collection box.
[0019] The beneficial effects of this utility model are:
[0020] By setting up a feeding mechanism, the rice entering through the feed hopper can enter the storage tank. The rotation of the rotating column can drive the rice to be fed evenly and intermittently, which can avoid excessive feeding of rice at one time, thereby ensuring the stability of the subsequent rice dehulling and screening processes.
[0021] By setting up a hulling mechanism, flexible rubber rollers are used to squeeze and rub the rice to break and tear it apart. This design avoids the mechanical damage to brown rice caused by traditional machinery and reduces the broken rice rate.
[0022] By setting up a screening mechanism, the hulled brown rice can be screened through the vibration of the screen frame, thereby separating broken rice and ensuring the quality of the output brown rice.
[0023] This invention enables uniform intermittent feeding of rice, avoiding excessive feeding of rice at one time, thus ensuring the stability of the subsequent rice dehulling and screening processes. At the same time, the use of flexible dehulling avoids mechanical damage to brown rice caused by traditional machinery, reduces the broken rice rate, and can screen out broken rice, ensuring the quality of the output brown rice.

A rotating column 21 is fixedly sleeved on the side wall of the second rotating shaft 20 inside the housing 1. Multiple storage troughs 22 are evenly arranged along the circumference of the side wall of the rotating column 21. Rice entering through the feed hopper 2 can enter the storage troughs 22. By rotating the rotating column 21, the rice can be fed evenly and intermittently, which can avoid excessive feeding of rice at one time, thereby ensuring the stability of the subsequent rice hulling and screening process.
[0035] The shell-removing mechanism includes two first rotating shafts 14 disposed inside the housing 1. One end of the first rotating shaft 14 is rotatably connected to the inner wall of the housing 1, and the other end of the first rotating shaft 14 passes through the inner wall of the housing 1 and extends to the outside of the housing 1. Flexible rubber rollers 24 are fixedly sleeved on the side walls of the two first rotating shafts 14 inside the housing 1, and gears 13 are fixedly sleeved on the side walls of the two first rotating shafts 14 outside the housing 1. The two gears 13 mesh, and through the transmission of the gears 13, the two first rotating shafts 14 can be made to rotate in opposite directions.
[0036] The screening mechanism includes a screen frame 5 installed inside the casing 1. The screen frame 5 is inclined and extends into a movable groove 4.

Two connecting plates 26 are fixed to the lower end of the screen frame 5. Two guide rods 29 are fixed between the two connecting plates 26. The two guide rods 29 pass through the two fixed plates 27 and are slidably connected to the fixed plates 27. Two springs 28 are sleeved on the guide rods 29. The two springs 28 are respectively located on both sides of the fixed plates 27. A linear vibration motor 25 is installed at the lower end of the screen frame 5.
