Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice grading screen. Background Art

[0002] Grading screens, also known as screening machines, are currently the most commonly used screening machines in China. During grain processing, rice grains are husked and then transformed into individual rice grains. However, rice grains vary in size, and even during the husking process, some broken rice grains often appear due to the quality of the rice grains themselves and mechanical reasons. To ensure the quality of rice and to meet consumer demand, it is necessary to separate good-looking, plump, unplump, and broken rice grains to ensure the grade and standard of rice.

[0003] When using some existing rice screening equipment, the screen is tilted, and then the rice is moved by gravity, and then the rice is processed through the screen for screening. This screening method is difficult to completely remove impurities in the rice when there is a lot of rice, and multiple screenings are required, which increases the time of rice screening. Utility Model Content

[0007] The rotary motor is arranged at one side of the screening box and is used for driving the screening box to move laterally.

[0008] Preferably, an L-shaped support plate is fixedly installed on the top of the fixed base, a rotating motor is fixedly installed on the bottom of the L-shaped support plate, the rotating shaft of the rotating motor extends to the top of the L-shaped support plate and is fixedly installed with a rotating rod, and a cam is fixedly installed on the outer wall of the rotating rod.

[0009] Preferably, a support plate is fixedly installed on the top of the fixed base, a driving motor is fixedly installed on one side of the support plate, a rotating shaft of the driving motor extends to one side of the support plate and is fixedly installed with a rotating rod, a rotating disk is fixedly installed on one end of the rotating rod, a return spring is fixedly installed on one side of the rotating disk, a screening box is fixedly installed on one side of the return spring, a sliding rod is fixedly installed on one side of the screening box, a fixed sleeve is fixedly installed on one side of the rotating disk, one end of the sliding rod extends to the inside of the fixed sleeve and the fixed sleeve and the sliding rod are slidably installed.

[0010] Preferably, a first filter plate and a second filter plate are fixedly mounted on inner walls on both sides of the screening box, and the second filter plate is located below the first filter plate.

[0011] Preferably, a material delivery pipeline is fixedly installed on the top of the first filter plate, one end of the material delivery pipeline extends to the bottom of the first filter plate and a stop valve is provided on the material delivery pipeline.

[0012] Preferably, the outer wall of the cam contacts one side of the screening box and is not fixed, so that the subsequent rotation of the screening box is facilitated.

[0013] Compared with the prior art, the beneficial effect of the present invention is that the rice grading screen can flip the screening box by the setting of the driving motor, so that after the rice is screened by the second filter plate, the first filter plate is moved downward by rotation, and the rice is screened again by the first filter plate. This screening method does not require the rice to be transported, thereby saving the time of rice processing and improving the efficiency of rice screening. The cam can be rotated by the setting of the rotating motor, and the cam can cyclically knock on the screening box when rotating, thereby causing the rice inside the screening box to move, so that the impurities in the rice are screened by the first filter plate and the second filter plate. This screening method can completely remove the impurities contained in the rice, reduce the steps of repeated rice screening, reduce the time of rice screening, and further improve the practicality of the device.
