Description

Technical Field

[0001] This application relates to the technical field of rice milling machines, and in particular to a portable germ rice milling machine. Background Technology

[0002] Rice germ is rich in protein, fat, soluble sugars, and various vitamins and trace elements. It also contains special components such as phytosterols and oryzanol. The nutrients in rice germ account for more than 70% of the total nutrients in rice. Rice with a germ retention rate of over 80% after milling and meeting rice grading standards is called "germ rice." Compared with ordinary rice, germ rice has higher nutritional value. Therefore, in recent years, the processing of germ rice has received much attention from the rice milling industry worldwide.

[0003] Currently, rice milling machines are commonly used to remove the husk from the rice germ. Utility model patent CN201320474Y discloses a germ rice milling machine, comprising: a frame, a motor mounted on the frame, a brown rice feed hopper, a germ rice discharge hopper, a rotating shaft located above the motor and mounted on the frame via two bearing seats, a transmission component, milling rollers, a sleeve rice sieve fitted over the milling rollers with a feed inlet and a discharge outlet, and a controller. The milling rollers consist of a propulsion screw fixedly connected to or integrated with the rotating shaft, and 1-5 parallel sand rollers with a particle size of 20-60 mesh fixedly fitted onto the rotating shaft. This utility model uses a set of sand rollers with different sand particle fineness as milling rollers, achieving gentle friction with the rice grains during use, thus preventing rice breakage during milling, increasing the whole rice yield, and preserving all the germ of the rice. The resulting germ rice retains its nutritional components, making it more beneficial to human health. It is suitable for rice shops and farmers to produce, consume, and sell germ rice.

[0004] However, when it is necessary to quickly test germ rice samples in experimental fields of agricultural colleges or research institutions, the rice milling machine mentioned above is inconvenient to carry due to its large size and the small volume of germ rice samples, which also affects the testing efficiency. Utility Model Content

[0005] To improve the portability and ease of use of rice milling machines, this application provides a portable germ rice milling machine.

[0006] This application provides a portable germ rice milling machine, which adopts the following technical solution:

[0007] A portable germ rice milling machine includes a housing, inside which are a rice milling section and a feeding section. A bracket is installed on the bottom wall of the rice milling section, and a motor support is installed on the top surface of the bracket. A screen box is installed on one side of the motor support, and a rice screen is installed inside the screen box. One end of the top surface of the rice screen has a feed inlet, and the other end has a discharge outlet. A funnel is installed on the top surface of the housing, and the funnel is connected to the feed inlet. A milling component for milling germ rice is installed inside the rice screen. The discharge outlet is connected to the feeding section, and an adjustment component for adjusting the diameter of the discharge outlet is installed in the feeding section.

[0008] By adopting the above technical solution, when it is necessary to break the husk of germ rice, the diameter of the discharge port is first adjusted by adjusting the component according to the actual requirements of rice milling fineness. After adjustment, the germ rice is placed in the funnel and enters the rice screen through the feed port. Then, the grinding component grinds and breaks the husk of the germ rice in the rice screen. At this time, the rice husk is collected in the rice milling section through the rice screen. The broken germ rice is collected in the discharge section through the discharge port, thus completing the breaking of the germ rice. The rice milling machine has a simple overall structure and small size, which helps to improve the convenience of carrying and using the rice milling machine.

[0009] Optionally, the grinding assembly includes a drive motor and a worm gear cutter. The drive motor is disposed on the top surface of the motor bracket, and the worm gear cutter is rotatably disposed inside the rice sieve. The output shaft of the drive motor passes through the motor bracket, and the output shaft of the drive motor is coaxially and fixedly connected to the worm gear cutter.

[0010] By adopting the above technical solution, when the drive motor is started, the output shaft of the drive motor drives the worm gear cutter to rotate. At this time, the worm gear cutter and the rice screen cooperate to grind and break the husk of the germ rice. With the continuous rotation of the worm gear cutter, the rice husk is collected in the grinding space through the rice screen, and the broken germ rice is collected in the feeding space through the discharge port, which helps to improve the stability of germ rice grinding.

[0011] Optionally, the adjustment assembly includes a plug and an adjustment screw. The inner wall of the feeding section is provided with a rice dispensing box, and the inner wall of the rice dispensing box is provided with a vertical plate. A nut is fixedly provided on one side of the vertical plate. One end of the adjustment screw passes through the outer shell of the box and the vertical plate in sequence. The plug is inserted into the discharge port. One end of the adjustment screw is fixedly connected to the plug. The nut is threadedly connected to the adjustment screw.

[0012] By adopting the above technical solution, when it is necessary to improve the grinding precision, the adjusting screw is turned inward. Under the action of the nut, the adjusting screw drives the plug to move towards the discharge port. By compressing the diameter of the discharge port, the grinding time of germ rice in the rice sieve is increased, which is conducive to improving the grinding quality of germ rice.

[0013] Optionally, the inner wall of the rice sieve is provided with multiple grinding belts.

[0014] By adopting the above technical solution, multiple grinding belts and worm gear cutters work together to grind germ rice, which helps to improve the quality of germ rice grinding in the rice sieve.

[0015] Optionally, shock-absorbing pads are provided between the bracket and the motor support, and between the screen box and the motor support.

[0016] By adopting the above technical solution, the vibration of the drive motor is reduced by the shock-absorbing pad, which helps to improve the overall stability of the rice milling machine.

[0017] Optionally, a rice milling section is provided with a rice bran receiving box, which is slidably connected to the outer shell of the box.

[0018] By adopting the above technical solution, when the rice husks are sieved from the rice sieve, they are collected in the bran collection box. When it is necessary to clean the rice husks in the collection box, the collection box is removed from the rice milling machine, which helps to improve the stability of rice husk collection and cleaning.

[0019] Optionally, the feeding area is provided with a rice receiving box, which is slidably connected to the outer shell of the box.

[0020] By adopting the above technical solution, the germinated rice after being broken falls from the outlet of the rice sieve and is collected in the rice collection box. The rice collection box is then removed from the outer shell of the box, which helps to improve the stability of collecting and removing germinated rice.

[0021] Optionally, a baffle is provided on the top surface of the screen box.

[0022] By adopting the above technical solution, the action of the baffle helps to prevent germ rice from splashing out of the top surface of the screen box during the milling process.

[0023] Optionally, a handle is hinged to the top surface of the housing.

[0024] By adopting the above technical solution, the rice milling machine can be carried by a handle, which improves the convenience of carrying the rice milling machine.

[0025] In summary, this application has the following beneficial technical effects:

[0026] When it is necessary to break the husk of germ rice, first adjust the diameter of the discharge port according to the actual requirements of rice milling fineness by adjusting the adjustment component. After adjustment, place the germ rice in the funnel. The germ rice enters the rice screen through the feed port through the funnel. Then, the grinding component grinds and breaks the husk of the germ rice in the rice screen. At this time, the rice husk is collected in the rice milling section through the rice screen. The broken germ rice is collected in the discharge section through the discharge port, thus completing the breaking of germ rice. The rice milling machine has a simple overall structure and small size, which helps to improve the convenience of carrying and using the rice milling machine. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Example:

[0034] See Figures 1-4A portable germ rice milling machine includes a rectangular outer shell 1. The outer shell 1 is divided into a milling section 2 and a feeding section 3. A bracket 4 is fixedly installed on the inner bottom wall of the milling section 2, and a motor bracket 5 with an L-shaped cross-section is fixedly connected to the top surface of the bracket 4. A screen box 6 is fixedly connected to one side of the motor bracket 5, and a rice screen 7 is fixedly assembled inside the screen box 6. A feeding port 8 is opened at one end of the top surface of the rice screen 7 for feeding germ rice. A funnel 25 is fixedly connected to the top surface of the outer shell 1, and the bottom end of the funnel 25 extends into the milling section 2, communicating with the feeding port 8. A grinding assembly is installed inside the rice screen 7 for grinding the germ rice fed into the rice screen 7. The sieve 7 has a discharge port 9 at one end facing the feeding section 3, and the discharge port 9 is connected to the feeding section 3. The feeding section 3 is equipped with an adjustment component, which is used to adjust the diameter of the discharge port 9.

[0035] In this embodiment, the rice milling machine has an overall size of 364*202*203mm, and its structure is simple and lightweight. When the rice milling machine is needed to break the husk of germ rice, an appropriate amount of germ rice is first placed into the funnel 25. The germ rice is fed into the rice screen 7 through the feed port 8 along the funnel 25. At this time, the milling assembly grinds the germ rice in the rice screen 7. The milled germ rice is divided into two parts: husk and rice. The husk falls through the mesh of the side wall of the rice screen 7 and is collected in the rice milling section 2, while the rice is collected in the discharge section 3 through the discharge port 9 of the rice screen 7. The breaking of the germ rice is completed.

[0036] For details, see Figure 2 and Figure 3 The grinding assembly includes a drive motor 10 and a worm gear cutter 11. The drive motor 10 is fixedly mounted on the top surface of the motor bracket 5, and a built-in power supply (not shown in the figure) is installed in the bracket 4, which is electrically connected to the drive motor 10. The worm gear cutter 11 is horizontally arranged and rotatably mounted inside the rice sieve 7. The drive shaft of the drive motor 10 passes through the motor bracket 5 and extends into the rice sieve 7, and the drive shaft of the drive motor 10 is coaxially and fixedly connected to the worm gear cutter 11.

[0037] Among them, see Figure 3 and Figure 4 The worm gear cutter 11 includes a spiral conveying part 12 and a grinding part 13. The spiral conveying part 12 is located at the feed inlet 8 of the rice screen 7, and the grinding part 13 is located inside the rice screen 7.

[0038] When the drive motor 10 starts, the drive shaft of the drive motor 10 drives the worm cutter 11 to rotate. At this time, the worm cutter 11 feeds the germ rice at the feed port 8 into the rice screen 7 through the spiral conveying part 12. The worm cutter 11 then grinds the germ rice in the rice screen 7 through the grinding part 13.

[0039] It is worth mentioning that, see Figure 3 To improve the quality of milling, a milling belt 14 is fixedly connected to the inner wall of the rice sieve 7. There are four milling belts 14, which are evenly distributed on the inner wall of the rice sieve 7.

[0040] When the worm gear cutter 11 rotates, the worm gear cutter 11 and the grinding belt 14 cooperate with each other to grind the germ rice, thereby improving the quality of germ rice grinding.

[0041] In addition, in this embodiment, the sieve gap is 1.2mm. After testing, it was found that a sieve with a gap of 1.2mm is beneficial to increasing the yield of germ rice.

[0042] For details, see Figure 2 and Figure 3 The adjusting assembly includes a plug 15 and an adjusting screw 16. A rice dispensing box 17 is fixedly connected to the inner wall of the feeding section 3, and a vertical plate 18 is fixedly connected to the inner wall of the rice dispensing box 17. A nut 19 is fixedly connected to the side wall of the vertical plate 18. The adjusting screw 16 is installed on the side wall of the outer shell 1, and its fixed end passes through the outer shell 1, the nut 19, and the vertical plate 18 in sequence. The nut 19 is threadedly connected to the adjusting screw 16. The plug 15 is used to adjust the size of the discharge port 9. The plug 15 is inserted into the discharge port 9, and the fixed end of the adjusting screw 16 is fixedly connected to the plug 15.

[0043] When it is necessary to move the plug 15 closer to the discharge port 9, the threaded adjusting screw 16 is rotated. Under the action of the nut 19 and the guiding action of the housing 1, the adjusting screw 16 moves the plug 15 closer to the discharge port 9. By reducing the diameter of the discharge port 9, the discharge rate of germ rice is slowed down, and the milling time of germ rice is extended, thereby improving the quality of germ rice milling.

[0044] See Figure 2 To reduce the vibration force when the drive motor 10 is driven, shock-absorbing pads 20 are fixedly installed between the bracket 4 and the motor support 5, and between the screen box 6 and the motor support 5. The shock-absorbing pads 20 buffer and reduce the vibration frequency of the drive motor 10, thereby improving the overall stability of the rice milling machine.

[0045] See Figure 2 To facilitate the collection of rice husks after the rice has been broken, a husk collection box 21 is inserted into the rice milling section 2, and the husk collection box 21 is slidably connected to the outer shell 1 of the box.

[0046] After being milled, the rice husks fall from the rice sieve 7 and are collected in the bran collection box 21, which helps to improve the collection of rice husks and the stability of cleaning them from the rice milling machine.

[0047] See Figure 2 In order to facilitate the collection of rice after the shells are broken, a rice collection box 22 is inserted into the feeding section 3, and the rice collection box is slidably connected to the outer shell 1 of the box.

[0048] After the rice is hulled, it falls from the discharge port 9 of the rice sieve 7 and is collected in the rice collection box 22. When it is time to remove the rice, the rice collection box 22 is simply removed from the feeding section 3, which is simple and convenient.

[0049] See Figure 2 To prevent rice husks from splashing onto the top surface of the sieve box 6, a baffle 23 is fixedly connected to the top surface of the sieve box 6. When rice husks splash, the baffle 23 blocks the rice husks so that they can be collected in the chaff collection box 21.

[0050] See Figure 1 Furthermore, to facilitate carrying the rice milling machine, a handle 24 is hinged to the top surface of the outer shell 1. Carrying the rice milling machine via the handle 24 improves its portability.

[0051] The working principle of a portable germ rice milling machine:

[0052] Carry the rice milling machine to the required application scenario via handle 24. Before using the rice milling machine, adjust the diameter of the discharge port 9 according to the required milling fineness. First, rotate the adjusting screw 16 by thread. Under the action of nut 19 and guided by the outer shell 1, the adjusting screw 16 drives the plug 15 to move closer to the discharge port 9. By reducing the diameter of the discharge port 9, the output of germ rice is reduced, and the milling time of germ rice is extended, thereby improving the quality of germ rice milling.

[0053] After adjusting the diameter of the discharge port 9, germinated rice is placed into the funnel 25, and the drive motor 10 is started. The drive shaft of the drive motor 10 drives the worm gear cutter 11 to rotate. At this time, the worm gear cutter 11 feeds the germinated rice from the feed port 8 into the rice sieve 7 through the screw conveyor 12. The worm gear cutter 11 then grinds the germinated rice in the rice sieve 7 through the grinding section 13. The ground rice husks are collected in the bran collection box 21 through the gaps in the rice sieve 7, and the ground rice is collected in the rice collection box 22 through the discharge port 9 of the rice sieve 7. Finally, the rice is taken out through the rice collection box 22, completing the grinding of the germinated rice.

[0054] In summary, the rice milling machine has a simple overall structure and small size, which helps to improve the convenience of carrying and using the rice milling machine.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
