[0002] A rice vibrating screen is a mechanical device used for grading and removing impurities from rice. It mainly achieves particle separation through vibration. Its core functions include removing impurities such as stones and husks, grading broken rice from whole rice grains, and separating rice grains of different sizes. The vibrating motor drives the screen body to generate high-frequency vibration, and the material moves on the screen surface along a trajectory, such as horizontal, elliptical, or straight line, and is separated by density difference or particle size.

[0003] During rice processing, vibrating screens are used to remove straw and husks from the rice. Most current vibrating screens are single-pass screens with short screening times and few gradations. When removing straw and husks from the rice, a large amount of rice is discharged from the slag outlet, resulting in increased rice loss from the vibrating screen. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a low-loss impurity cleaning device for rice processing, which has the advantage of low rice loss and solves the problem of high rice loss in existing vibrating screens. Currently, most vibrating screens are single-pass screening with short screening time. When cleaning straw and rice husks from the rice, a large amount of rice is discharged from the slag discharge port, which leads to increased loss of the vibrating screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-loss impurity cleaning device for rice processing, comprising a vibrating box, a feeding funnel connected to the rear top of the vibrating box, a slag discharge box connected to the front side of the vibrating box, a discharge funnel connected to the middle bottom of the vibrating box, vibrating motors fixedly connected to the left and right sides of the bottom of the inner wall of the vibrating box, two partition plates fixedly connected to the top of the inner wall of the vibrating box, three screens connected to the bottom of the partition plates in a stepped arrangement, a rectangular groove structure opened in the middle of the front side of the partition plate, an electric gate plate installed inside the rectangular groove structure of the partition plate, the top of the electric gate plate extending to the top of the vibrating box, and compression springs connected to the four corners of the bottom of the vibrating box.

[0006] As a preferred embodiment of this invention, a connecting block is provided at the bottom of the vibration box and at the top of the compression spring, and the vibration box is fixedly connected to the compression spring through the connecting block.

[0007] In a preferred embodiment of this invention, a connecting plate is fixedly connected to the bottom of the compression spring, the bottom of the discharge funnel extends through to the bottom of the connecting plate, and a bracket is fixedly connected to the bottom of the connecting plate.

[0009] As a preferred embodiment of this invention, the surface of the vibration motor is covered with a protective shell, and the top of the protective shell is fixedly connected to the bottom of the vibration box.

[0010] As a preferred embodiment of this invention, the bottom of the bracket is fixedly connected with an anti-slip pad.

[0011] As a preferred embodiment of this invention, the screen is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model first uses a first-stage screen to perform preliminary vibration screening of rice. The screened rice falls to the bottom of the vibrating box and is discharged from the discharge funnel. After the preliminary screening time is over, a second-stage screen is used for secondary screening. After the secondary screening time is over, a third-stage screen is used for final screening of straw and rice husks. During screening, straw and rice husks are discharged from the slag discharge box. At this time, the rice can be screened in a stepped, multi-stage manner to achieve the effect of low rice loss.

[0013] 2. By setting a support plate, this utility model can support the electric gate and prevent the electric gate from falling off and being damaged during use. Attached Figure Description

[0028] The working principle and usage process of this utility model are as follows: First, the vibration motor 5 is started, which drives the vibration box 1 and the screen 7 to vibrate. Then, rice raw materials are poured into the vibration box 1 through the feed funnel 2. At this time, the first-stage screen 7 is used to perform preliminary vibration screening of the rice. The screened rice falls to the bottom of the vibration box 1 and is discharged from the discharge funnel 4. After the preliminary screening time is completed, the rear electric gate 8 is activated, causing the straw and rice husks, along with a small amount of rice, to fall onto the second-stage screen 7 for secondary screening. After the secondary screening time is completed, the front electric gate 8 is activated, causing the straw and rice husks, along with a small amount of rice, to fall onto the second-stage screen 7. The second-stage screen 7 is used for secondary screening. After the secondary screening time is completed, the front electric gate 8 is activated, causing the straw... The rice husks and straw fall onto the third-stage screen 7, where they are used for final sieving. Simultaneously, the straw and husks are discharged from the slag discharge box 3. This allows for multi-stage sieving of the rice, achieving low rice loss. The specific structure, control circuit, and control principle of the electric gate 8 are the same as those of existing electric-driven gates on the market. The time control of the electric gate 8 needs to be manually adjusted according to the ratio of rice to impurities. Different sizes of rice can be screened by changing the screen 7 with different apertures. The compression spring 10 adopts the spring structure used in existing vibrating screens on the market.
