AI Technical Summary
In the current rice production process, impurities such as stones and other hard materials can mix into the rice, damaging the grinding wheels of the rice milling machine and increasing equipment wear and tear.
A rice milling machine capable of separating impurities was designed. It uses a sorting disc to separate rice from impurities using centrifugal force. The rotation of the sorting disc throws the rice to the periphery, while heavier impurities remain on the surface of the sorting disc or fall directly into the sorting port, thus achieving the separation of impurities.
It effectively separates impurities from rice, protects the rice milling machine, prevents damage to the grinding wheel from hard impurities, and extends the service life of the equipment.

TECHNICAL FIELD
[0001] The application relates to the technical field of rice mills, in particular to a rice mill capable of separating sundries. BACKGROUND
[0002] China has vast rural areas, and the agricultural production is mainly rice planting, and China is known as a large rice planting country. In most areas, rice is the staple food. Rice is processed by removing the husk, sieving and sorting the bran. A rice mill is a device for removing the husk of rice by friction and grinding. After the brown rice passes through the whitening chamber of the rice mill, the iron roller or sand roller rotates under the action of internal pressure and the wind fan blows, so that the rice and the rice grains, the rice grains and the sieve plate, and the grains and the rice roller are fully rubbed and ground, so that the surface rice husk is removed, and a smooth and bright appearance is obtained.
[0003] Due to the limitation of the production process, stones and other sundries are inevitably mixed into the rice. If the stones are not removed, the high hardness of the stones will damage the grinding wheel during subsequent rice milling. CONTENT OF THE UTILITY MODEL
[0004] The application aims to overcome the above technical deficiencies and provide a rice mill capable of separating sundries, which solves the problem of damage to the rice mill caused by the mixing of sundries in the rice in the prior art.

DETAILED DESCRIPTION
[0019] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.
[0020] Referring to Figure 1 and Figure 2 , the embodiment provides a rice mill capable of separating impurities, which comprises a rice mill body 1, a sorting disc 2, a first material collecting groove 3 and a driving unit 4. The rice mill body 1 is used for crushing rice hulls. The sorting disc 2 is used for screening impurities in rice. The first material collecting groove 3 is used for receiving rice thrown by the sorting disc 2. The driving unit 4 is used for driving the sorting disc 2 to rotate.
[0021] A feeding port 1a is formed in the upper end of the rice mill body 1, which is used for conveying rice into the rice mill body 1.
[0022] The sorting disc 2 is arranged above the rice mill body 1. A sorting port 2a is formed in the center of the sorting disc 2. The top of the sorting disc 2 has a sorting surface 2b which is recessed towards the sorting port 2a. When the sorting disc 2 rotates, a centrifugal force is generated. The rice falling on the sorting disc 2 will be thrown to the periphery of the sorting disc 2 and leave the sorting surface 2b. The impurities such as stones mixed in the rice are difficult to be thrown away due to their large weight, and thus remain on the surface of the sorting disc 2. Some impurities with particularly large weight may directly slide along the sorting surface 2b and fall into the sorting port 2a. When the sorting disc 2 stops rotating, the impurities on the surface of the sorting disc 2 will slide along the sorting surface 2b due to gravity and fall into the sorting port 2a. Preferably, the rice mill capable of separating impurities further comprises a second material collecting groove 5 arranged below the sorting port 2a, which is used for carrying the materials falling in the sorting port 2a. The impurities mixed in the rice will fall from the sorting port 2a into the second material collecting groove 5.
[0023] The first material collecting groove 3 is arranged below the sorting disc 2. The first material collecting groove 3 is provided with a containing cavity 3a which is enclosed outside the sorting disc 2, and is used for carrying the materials falling on the periphery of the sorting disc 2. The rice thrown by the sorting disc 2 will enter the containing cavity 3a, and thus be enriched in the first material collecting groove 3. Preferably, the first material collecting groove 3 is provided with a discharge port 3b corresponding to the feeding port 1a, which is used for conveying the rice in the first material collecting groove 3 to the feeding port 1a. Preferably, the bottom end of the containing cavity 3a is inclined, and the discharge port 3b is in communication with the lower side of the containing cavity 3a. Therefore, the rice in the containing cavity 3a will slide along the bottom surface to the discharge port 3b, that is, the self-flow of the rice is realized. In actual application, the discharge port 3b and the feeding port 1a can be in communication through a hose, or a hopper is arranged on the feeding port 1a to receive the rice conveyed by the discharge port 3b, so as to avoid the rice from spilling.
[0024] The driving unit 4 is connected with the sorting disc 2 to drive the sorting disc 2 to rotate. Preferably, the driving unit 4 is an electric motor, and a belt drive or a gear drive can be used between the driving unit 4 and the sorting disc 2. Preferably, the rice mill capable of separating impurities further comprises a mounting frame 6, the mounting frame 6 is fixedly connected with the rice mill body 1, the sorting disc 2 is rotatably connected with the mounting frame 6, and the driving unit 4 is fixedly connected with the mounting frame 6.
[0025] Preferably, the sorting disc 2, the first material collecting groove 3 and the driving unit 4 are provided in multiple groups. A single group of the sorting disc 2, the first material collecting groove 3 and the driving unit 4 has limited sorting efficiency, and when higher flow is required, multiple groups of the sorting disc 2, the first material collecting groove 3 and the driving unit 4 can be set to work together to improve the sorting efficiency. Further preferably, the rice mill capable of separating impurities further comprises a material collecting hopper 7, the material collecting hopper 7 is arranged above the rice mill body 1, the material collecting hopper 7 is provided with a discharge opening 7a, the discharge opening 7a is located above the sorting surface 2b, and the material collecting hopper 7 is used to contain the rice to be sorted, wherein the rice enters the sorting surface 2b from the discharge opening 7a. When multiple groups of the sorting disc 2, the first material collecting groove 3 and the driving unit 4 are arranged, multiple discharge openings 7a are also arranged, each of which corresponds to the sorting surface 2b of a different sorting disc 2.
[0026] Preferably, the side of the material collecting hopper 7 extends outwardly and forms multiple first supporting legs 7b, and the multiple first supporting legs 7b abut against the upper side of the rice mill body 1 to support the material collecting hopper 7.
[0027] Preferably, the bottom side of the rice mill body 1 extends downwardly and forms multiple second supporting legs 1b, and the multiple second supporting legs 1b are used to support the rice mill body 1.
[0028] In summary, the rice mill capable of separating impurities provided by the present application can separate the impurities in the rice. When the sorting disc 2 rotates, the rice falling on the sorting surface 2b will be thrown outwardly due to centrifugal force, and the impurities with large weight will be difficult to move along the sorting surface 2b due to small centrifugal force, and thus the impurities will be left on the sorting surface 2b or directly fall into the sorting opening 2a.
[0029] The specific embodiments of the present application do not constitute a limitation on the protection scope of the present application. Any other corresponding changes and modifications made according to the technical concept of the present application shall be included in the protection scope of the claims of the present application.
