Description

Technical Field

[0001] The utility model relates to the technical field of rice mills, in particular to a gravity-fed rice grading mechanism for a rice mill. Background Art

[0002] A rice mill is a device used to remove the husk and polish brown rice. It removes the outer skin of brown rice through mechanical force to obtain edible rice. With the development of technology, rice mills are also constantly progressing and innovating. Among them, an intelligent rice mill is a fully automated device that combines the characteristics of a vending machine and a traditional rice mill. The operator only needs to pre-store the paddy in the machine. When purchasing rice, consumers can select the purchase type, weight and pay through the screen, and then the machine can mill fresh rice in a short time. The entire processing process of the intelligent rice mill is presented in front of consumers, providing consumers with freshly milled rice, which is highly praised by consumers and has a very broad application prospect.

[0003] The intelligent rice mill mainly includes three main parts: a hulling machine, a germ rice mill and a polished rice mill. The hulling machine removes the husk of paddy to make brown rice, and the germ rice mill and the polished rice mill respectively carry out moderate processing and fine processing on the brown rice to obtain germ rice and polished rice. During the processing, when consumers choose to buy brown rice, it is necessary to store and discharge the brown rice produced by the hulling machine. In addition, when consumers choose to buy germ rice or polished rice, it is also necessary to feed the germ rice mill and the polished rice mill respectively. If feeding mechanisms are designed separately for the germ rice mill and the polished rice mill, it will lead to an increase in production costs. Moreover, when milling germ rice or polished rice, if the storage amount of brown rice is insufficient, it is necessary to mill brown rice first, resulting in an extended milling time and a reduced milling efficiency, which affects the comfort of consumers' experience. The above problems need to be solved urgently. Summary of the Utility Model

For the convenience of description, only the parts related to this embodiment are shown and are described in detail as follows:

[0033] Please combine Figures 2-5 , a self-flow type decimeter mechanism for a rice milling machine, including a feed channel 1. A first discharge channel 2 is provided below the feed channel 1. A second discharge channel 3 and a third discharge channel 4 are respectively provided on both sides of the feed channel 1. The first discharge channel 2, the second discharge channel 3 and the third discharge channel 4 are all communicated with the feed channel 1. The feed channel 1 is connected to a rice hulling machine. The first discharge channel 2 is connected to a weighing scale.

[0034] By setting a first discharge channel 2, a second discharge channel 3, and a third discharge channel 4 on the feed channel 1, the feed channel 1 is connected to a rice huller, and the first discharge channel 2 is connected to a weighing scale, which is used to realize the storage and unloading of brown rice. The second discharge channel 3 and the third discharge channel 4 are respectively connected to a germ rice milling machine and a white rice milling machine, which are used to realize the feeding of brown rice. The four-way design can realize the automatic distribution of rice grains without power drive, eliminating the need to separately design feeding mechanisms for the germ rice milling machine and the white rice milling machine, and eliminating the need to transport brown rice, reducing the damage of rice grains, reducing the occupied space, improving the milling efficiency, and reducing the production cost.

[0035] By setting a high-level sensor 5 and a low-level sensor 6 on the first discharge channel 2, the second discharge channel 3, and the third discharge channel 4, both the high-level sensor 5 and the low-level sensor 6 are electrically connected to the rice huller. When any rice storage level is low, the rice huller starts to mill rice. When the rice storage amounts reach the highest levels, the rice huller stops milling rice, realizing the automatic detection of the rice level and the timely replenishment of rice grains.

[0036] Specifically, please refer to Figures 1-2 At the top of the feed channel 1, there is a feed inlet 7, and the feed inlet 7 is connected to the discharge outlet of the rice huller, which is used to feed the rice distribution mechanism. At the bottom of the first discharge channel 2, the second discharge channel 3, and the third discharge channel 4, there are respectively a first discharge outlet 8, a second discharge outlet 9, and a third discharge outlet 10. The first discharge outlet 8 is used to unload brown rice, and the second discharge outlet 9 and the third discharge outlet 10 are respectively connected to the feed inlets of the germ rice milling machine and the white rice milling machine, which are used to feed the germ rice milling machine and the white rice milling machine.

[0037] Please refer to Figures 1-2 Please refer to

[0038] Please refer to Figure 2 and Figure 4 In the first discharge channel 2, there is a bracket 11, and on the bracket 11, there is a telescopic push rod 12. Inside the first discharge outlet 8, there is a discharge baffle 13, and the end of the telescopic push rod 12 is connected to the discharge baffle 13. When rice needs to be unloaded, by driving the telescopic push rod 12 to drive the discharge baffle 13 to move or flip, the first discharge outlet 8 is opened, and the brown rice stored in the first discharge channel 2 automatically flows out, realizing the unloading of brown rice. After the unloading is completed, driving the telescopic push rod 12 again to drive the discharge baffle 13 to move or flip, so that the discharge baffle 13 returns to its original position, and the first discharge outlet 8 can be closed.

[0039] Please refer to Figure 2 and Figure 4 , the rice unloading baffle 13 is hinged or snap-fitted to the first discharge port 8; when the rice unloading baffle 13 is hinged to the first discharge port 8, the telescopic push rod 12 drives the rice unloading baffle 13 to flip, opening the first discharge port 8; when the rice unloading baffle 13 is snap-fitted to the first discharge port 8, the telescopic push rod 12 drives the rice unloading baffle 13 to move up and down, opening the first discharge port 8.

[0040] Please refer to Figure 2 and Figure 4 , the telescopic push rod 12 can be an electric push rod or a hydraulic push rod, or other types of telescopic push rods, as long as it can drive the rice unloading baffle 13 to move or flip. In actual use, the type of the telescopic push rod 12 depends on the specific working conditions.

[0043] The brown rice obtained by the hulling machine flows into the first discharge channel 2, the second discharge channel 3, and the third discharge channel 4 through the feed port 1 respectively and is stored in the three discharge channels; when the rice level in any one storage position is low, the low-level sensor 6 transmits a signal to the control system, and the control system drives the hulling machine to start and begin rice milling; when the rice storage amounts in the three discharge channels all reach the highest rice level, the high-level sensor 5 transmits a signal to the control system, and the control system controls the hulling machine to stop rice milling, realizing automatic detection of the rice level and timely replenishment of rice grains.

[0044] When it is necessary to unload the brown rice, the control system drives the telescopic push rod 12 to work. The telescopic push rod 12 drives the rice unloading baffle 13 to move or flip, opening the first discharge port 8. The brown rice stored in the first discharge channel 2 automatically flows out and falls onto the weighing scale, realizing the unloading of the brown rice; when the weight of the brown rice reaches the requirement, the weighing scale transmits a signal to the control system, and the control system drives the telescopic push rod 12 again to drive the rice unloading baffle 13 to move or flip, so that the rice unloading baffle 13 resets and closes the first discharge port 8, and the unloading ends.

[0045] When it is necessary to mill brown rice into germinated rice or polished rice, since the second discharge port 9 and the third discharge port 10 are respectively connected to the feed ports of the germinated rice milling machine and the polished rice milling machine, at this time, only need to drive the germinated rice milling machine and the polished rice milling machine to work through the control system to carry out milling, without separate feeding.

[0046] Embodiment 2

[0047] Please refer to Figure 6 , which is the schematic main sectional structure diagram of a gravity-fed rice separation mechanism for a rice milling machine provided by Embodiment 2 of the present application. For the convenience of description, only the parts related to this embodiment are shown and are described in detail as follows:

[0048] Compared with Embodiment 1, the difference in this embodiment is that: an inclined separation net 14 is provided in the first discharge channel 2. The separation net 14 divides the first discharge channel 2 into an upper channel 201 and a lower channel 202. The bottom ends of the upper channel 201 and the lower channel 202 are respectively provided with a whole rice discharge port 801 and a broken rice discharge port 802. During use, the brown rice entering the upper channel 201 first falls onto the separation net 14, and the broken rice passes through the separation net 14 and falls into the lower channel 202, flowing out from the broken rice discharge port 802, and the complete whole rice remains in the upper channel 201 and flows out from the whole rice discharge port 801 along the arc of the separation net 14.

[0049] Specifically, please refer to Figure 6 , a bracket 11 is provided in the upper channel 201, and a rice unloading baffle 13 is provided in the whole rice discharge port 801. The separation net 14 is inclined downward, and the separation net 14 has the function of automatically separating impurities. Compared with Embodiment 1, in this embodiment, by setting the separation net 14 to separate broken rice and whole rice, it helps to improve the purity of brown rice and reduce the influence of impurities on the finished product quality.

[0050] Please refer to Figure 6 , an oscillator 15 is provided on the separation net 14. The oscillator 15 vibrates the brown rice falling on the separation net 14, accelerating the broken rice to fall into the lower channel 202, and at the same time accelerating the whole rice to flow out from the whole rice discharge port 801 to prevent the rice grains from aggregating.

[0051] Please refer to Figure 6 , a collection trough 16 is connected to the broken rice discharge port 802 for collecting broken rice to avoid waste.

[0052] The following combines Figure 6 , and describes the working process of a gravity-fed rice separation mechanism for a rice milling machine in this embodiment as follows:

[0053] The brown rice obtained by the rice huller flows into the first discharge channel 2, the second discharge channel 3, and the third discharge channel 4 respectively through the feed inlet 1 and is stored in the three discharge channels; when the rice level in any one of the channels is low, the low-level sensor 6 transmits a signal to the control system, and the control system drives the rice huller to start working to produce rice; when the rice storage levels in the three discharge channels all reach the highest level, the high-level sensor 5 transmits a signal to the control system, and the control system controls the rice huller to stop producing rice, realizing the automatic detection of the rice level and the timely replenishment of rice grains.

[0054] When it is necessary to discharge the brown rice, the oscillator 15 and the telescopic push rod 12 are driven to work through the control system. Under the action of the oscillator 15, the brown rice on the separation net 14 vibrates, and the broken rice grains fall into the lower channel 202 and flow out from the broken rice discharge port 802; at the same time, the telescopic push rod 12 drives the discharge baffle 13 to move or flip, opening the first discharge port 8, and the brown rice stored in the upper channel 201 flows out from the whole rice discharge port 801 along the arc of the separation net 14 and falls onto the weighing scale to realize the discharge of the brown rice; when the weight of the brown rice reaches the required value, the weighing scale transmits a signal to the control system, and the control system drives the telescopic push rod 12 again to drive the discharge baffle 13 to move or flip, so that the discharge baffle 13 returns to its original position and closes the first discharge port 8, and the discharge ends; the broken rice flowing out from the broken rice discharge port 802 enters the collection tank 16 for storage.

[0055] When it is necessary to mill the brown rice into germinated rice or polished rice, since the second discharge port 9 and the third discharge port 10 are respectively connected to the feed inlets of the germinated rice milling machine and the polished rice milling machine, at this time, only the germinated rice milling machine and the polished rice milling machine need to be driven to work through the control system to carry out milling, and there is no need for separate feeding.

[0056] The utility model provides a gravity-fed rice grading mechanism for a rice milling machine. By arranging a first discharge channel, a second discharge channel and a third discharge channel on the feeding channel, the feeding channel is connected to a rice hulling machine, and the first discharge channel is connected to a weighing scale for storing and discharging brown rice. The second discharge channel and the third discharge channel are respectively connected to a germ rice milling machine and a white rice milling machine for feeding brown rice. The four-way design enables automatic distribution of rice grains without power drive, eliminating the need for separate feeding mechanisms for the germ rice milling machine and the white rice milling machine and for transporting brown rice, reducing damage to rice grains, minimizing occupied space, improving rice milling efficiency and lowering production costs. By arranging high-level sensors and low-level sensors on the first discharge channel, the second discharge channel and the third discharge channel, both the high-level sensors and the low-level sensors are electrically connected to the rice hulling machine. When any of the rice storage levels is low, the rice hulling machine starts to produce rice. When the rice storage amounts reach the highest levels, the rice hulling machine stops producing rice, realizing automatic detection of the rice level and timely replenishment of rice grains. The utility model has a simple structure, is easy to operate, reduces damage to rice grains, improves rice milling efficiency, lowers production costs, has high practicability and can be widely applied to the technical field of rice milling machines.

[0057] The above-described embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
