Description

Technical Field

[0001] This application relates to the field of rice selection machine technology, and in particular to a strong magnetic adsorption rice drum selection machine. Background Technology

[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. Rice contains nearly 64% of the nutrients found in paddy and more than 90% of the nutrients needed by the human body. In the rice processing industry, the screening and impurity removal of rice are key steps to ensure product quality.

[0003] In practical use, it has been found that rice screening equipment can usually only remove impurities with inconsistent particle sizes through physical sieving. However, it lacks effective means to separate magnetic impurities that may be mixed in with rice. As a result, magnetic foreign objects may still remain in the finished rice, which not only affects the purity of the rice, but may also pose safety hazards in subsequent processing or consumption. Therefore, we have proposed a strong magnetic adsorption rice drum sorting machine to solve the above problems. Utility Model Content

The spiral blade 302 is provided on the conveying shaft 301 and is located inside the conveying cylinder 3. A gear mechanism is provided between the conveying shaft 301 and the transmission shaft 7.

[0038] Specifically, the gear mechanism includes two bevel gears 502. Both the conveying shaft 301 and the front end of the transmission shaft 7 are fixedly fitted with bevel gears 502. The bevel gears 502 are located inside the motor housing 5, and the two bevel gears 502 mesh with each other.

[0039] Specifically, the adsorption mechanism includes a rotating shaft 401 and a strong magnetic roller 402. The same rotating shaft 401 is rotatably mounted on the inner rear wall of the transmission box 6 and the inner front wall of the feeding pipe 4. The rotating shaft 401 is located to the lower left of the transmission shaft 7. The strong magnetic roller 402 is fixedly sleeved on the rotating shaft 401. The strong magnetic roller 402 is located inside the feeding pipe 4. A transmission mechanism is provided between the rotating shaft 401 and the transmission shaft 7.

[0040] Specifically, the transmission mechanism includes two transmission wheels 701 and a transmission belt 702. The transmission wheels 701 are fixedly sleeved on both the rotating shaft 401 and the transmission shaft 7. The transmission wheels 701 are located inside the transmission box 6, and the same transmission belt 702 is sleeved on the two transmission wheels 701.

[0041] Specifically, an inspection door 403 is provided on the right side of the feeding pipe 4, and a handle is provided on the inspection door 403.

[0042] Specifically, a support column 8 is fixedly installed at the bottom of the storage box 2. The support column 8 is located outside the conveying cylinder 3, and the bottom end of the support column 8 is fixedly connected to the top of the screening box 1.

[0043] Specifically, a discharge pipe 101 is provided on the left side of the screening box 1, and a waste discharge pipe 102 is provided on the right side of the screening box 1.

[0046] In this application, during operation, rice is first stored in the storage bin 2, and then enters the conveying cylinder 3 through the feeding pipe. By starting the motor 501, its output shaft drives the conveying shaft 301 to rotate, and the spiral blades 302 on the conveying shaft 301 rotate accordingly. During rotation, the spiral blades 302 continuously push the rice towards the feeding pipe 4, achieving uniform and quantitative conveying of rice from the conveying cylinder 3 to the screening box 1, thus improving the adsorption rate of magnetic impurities by the strong magnetic roller. Simultaneously, the rotation of the motor 501's output shaft, through the bevel gear 502 on the conveying shaft 301… The bevel gear 502 at the front end of the drive shaft 7 meshes with the drive shaft 7, which can drive the drive shaft 7 to rotate. The rotation of the drive shaft 7, in turn, drives the rotating shaft 401 to rotate through the drive wheel 701 and the drive belt 702 on it. This causes the strong magnetic roller 402, which is fixedly sleeved on the rotating shaft 401, to rotate inside the feeding pipe 4. During the rotation, the strong magnetic roller 402 can use its strong magnetism to attract magnetic impurities mixed in the rice to the surface of the roller, thereby achieving the purpose of removing magnetic impurities from the rice and ensuring the purity of the rice. The magnetic impurities on the surface of the strong magnetic roller 402 can be cleaned by opening the inspection door 403.

[0047] Subsequently, the rice enters the screening box 1 through the feeding pipe 4 and falls onto the screen 103. By activating the vibrating screen 104, the screen 103 vibrates, and qualified rice grains are discharged through the discharge pipe 101 under the vibration, thus achieving the collection of qualified rice. Impurities that do not meet the requirements, such as smaller foreign objects and broken rice, fall through the screen 103 onto the guide plate 105 and are discharged from the impurity discharge pipe 102 under the guidance of the guide plate 105, thus achieving the separation of impurities. Finally, the screening and impurity removal of rice is completed, thereby improving the quality and purity of the rice.
