[0026] Please refer to Figure 1-4 A rice milling machine with safety protection function includes a rice milling bin 1. A feeding hopper 5 is fixedly installed on the top surface of the rice milling bin 1, and a second drive motor 8 is fixedly installed on one side surface of the feeding hopper 5. The output end of the second drive motor 8 extends into the feeding hopper 5 and a distributing plate 9 is installed therein. A metering hopper 10 is opened on the surface of the distributing plate 9. A dustproof plate 12 is hinged to the inner wall of the feeding hopper 5 through a hinge 11, and a torsion spring 13 is installed between the dustproof plate 12 and the inner wall of the feeding hopper 5. A first drive motor 2 is fixedly installed on one side surface of the rice milling bin 1, and a rotating rice milling rod 3 is installed inside the rice milling bin 1 through the output end of the first drive motor 2. A fixed rice milling rod 4 is provided on the other side of the inside of the rice milling bin 1 to cooperate with the rotating rice milling rod 3.
[0027] In operation, rice is fed into the feeding hopper 5. Under gravity, the rice exerts a force on the dustproof plate 12. At this time, the torsion spring 13 deforms and stores energy, causing the dustproof plate 12 to open. The rice passes through the gap between the dustproof plates 12 and enters the rice milling chamber 1. The first drive motor 2 rotates, driving the connected rotating rice milling rod 3 to rotate. The rotating rice milling rod 3 and the fixed rice milling rod 4 interlock through hexagonal plum blossom-shaped edges to rub the rice. Meanwhile, the second drive motor 8 drives the distributing disc 9 to rotate. The distributing disc 9 rotates a certain number of times, which can quantitatively feed brown rice into the rice milling chamber 1, effectively reducing the risk of blockage during operation and ensuring the rice milling effect. By setting up the dustproof plate 12, after the rice passes through, the torsion spring 13 drives the dustproof plate 12 to return to its original position, which can seal the feeding hopper 5 and play a role in preventing dust during the feeding process, avoiding dust dispersion, reducing the harm caused by dust to the workers, and providing a safety protection effect. The design is ingenious and worth promoting.
[0028] In this implementation plan: a discharge port 6 is fixedly installed on the bottom surface of the rice milling bin 1, and a box door 7 is threadedly connected to the discharge port 6.
[0029] Specifically, opening the box door 7 allows for material discharge, while closing it allows for sealing the discharge port 6 during use.
[0030] In this embodiment, multiple metering hoppers 10 are provided, and the multiple metering hoppers 10 are arranged in a ring array on the surface of the dispensing plate 9.
[0031] Specifically, it can feed rice into the rice milling silo 1 in measured quantities for milling.
[0032] In this implementation plan: the length of the dustproof plate 12 is 1 / 2 of the width of the feed hopper 5.
[0033] Specifically, this ensures a tight seal on the feed hopper 5, preventing dust from flying around.
[0034] In this implementation scheme: the width of the multiple metering hoppers 10 is smaller than the width of the distributing plate 9.
[0035] Specifically, the metering hopper 10 can be installed on the distributing plate 9.
[0036] In this implementation plan: multiple dustproof plates 12 are provided, and the multiple dustproof plates 12 are equidistantly distributed on both sides of the inner wall of the feed hopper 5.
[0037] Specifically, the sealing effect is more ideal, and it is less likely to cause dust to fly.
[0038] In this embodiment: a switch 14 is fixedly installed on the outer wall of the rice milling bin 1, and the switch 14 is electrically connected to the first drive motor 2 and the second drive motor 8 through wires.
[0039] Specifically, the common circuit connection structure will not be elaborated on here.
[0040] In this implementation scheme: switch 14 is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.
[0041] Working Principle: During operation, rice is fed into the feed hopper 5. Under gravity, the rice exerts a force on the dustproof plate 12. At this time, the torsion spring 13 deforms and stores energy, causing the dustproof plate 12 to open. The rice passes through the gaps between the dustproof plates 12 and enters the rice milling chamber 1. The first drive motor 2 rotates, driving the connected rotating rice milling rod 3 to rotate. The rotating rice milling rod 3 and the fixed rice milling rod 4 interlock through hexagonal, plum-shaped edges to rub the rice. Meanwhile, the second drive motor 8 drives the distributing disc 9 to rotate. The distributing disc 9 rotates a certain number of times, quantitatively feeding brown rice into the rice milling chamber 1, effectively reducing the risk of blockage during operation and ensuring the rice milling effect. By setting up the dustproof plate 12, after the rice passes through, the torsion spring 13 drives the dustproof plate 12 to reset, sealing the feed hopper 5 and preventing dust from escaping during feeding. This reduces the harm caused by dust to workers, providing a safety protection effect. The ingenious design is worthy of promotion.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
