[0002] During the grain production and processing process, due to the quality of the rice itself and mechanical reasons, some broken rice will appear in the processed white rice. In order to ensure the quality of the white rice, the white rice needs to be screened according to different specifications and sizes, and the finished white rice needs to be graded and sorted to ensure the grade and standard of the rice.
[0003] Currently, most of the white rice grading screens on the market use a vibration motor to vibrate the screen to screen the grain. The vibration will cause the internal structure of the equipment to collide with each other during operation and produce noise. At the same time, when the grain is screened, some dust and impurities will adhere to the screen, requiring workers to regularly take out the screen and clean it, affecting the production efficiency of the equipment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In the embodiment, Figure 1-4 A white rice grading screen is provided, comprising a shell 1, a feed port 2 is arranged at the top of the shell 1, a dust removal assembly 3 is arranged inside the feed port 2, a mounting frame 4 is arranged inside the shell 1, a plurality of screen bodies 5 are arranged inside the mounting frame 4, a driving assembly 6 penetrating and extending into the shell 1 is arranged at the bottom of the shell 1, the driving assembly 6 comprises a reduction motor 61, a reduction motor 61 is fixedly installed at the bottom of the shell 1, an output end of the reduction motor 61 penetrates and extends into the shell 1, and a rotating rod 6 is fixedly installed on the output end of the reduction motor 61 2, a rotating disk 9 is rotatably mounted on one end of the rotating rod 62 away from the reduction motor 61, a spring shock absorber 7 located at the four bottom corners of the mounting frame 4 is fixedly mounted on the inner bottom end of the shell 1, a guide rail assembly 8 is arranged on the inner side of the four spring shock absorbers 7, and the guide rail assembly 8 includes an annular guide rail seat 81, an annular guide rail seat 81 is fixedly mounted on the inner bottom end of the shell 1, an annular guide rail top 82 opposite to the annular guide rail seat 81 is fixedly mounted on the bottom end of the mounting frame 4, and a rotating disk 9 located inside the guide rail assembly 8 is rotatably mounted on the output end of the driving assembly 6.
[0023] Through the above-mentioned structural arrangement, the reduction motor 61 is started, and the reduction motor 61 drives the rotating rod 62 to rotate, and the rotating rod 62 drives the rotating disk 9 to rotate slowly in the guide rail assembly 8. During the rotation process, the rotating disk 9 is moved to a position and lifted up, so that the mounting frame 4 shakes slightly with the rotating disk 9. As the mounting frame 4 shakes, the grain inside the screen 53 also moves back and forth on the screen 53 for screening. The elastic ball 54 also collides with the partition plate 52 and each other as it shakes, and bounces and hits the screen 53, thereby helping to enhance the screening effect. The annular guide rail seat 81 and the annular guide rail top 82 guide the moving direction of the rotating disk 9, and at the same time limit the rotating disk 9 to ensure its vertical rolling state.
[0024] Reference Figure 1-2 The dust removal assembly 3 includes a filter screen 31, the filter screen 31 is fixedly installed inside the feed port 2, the filter screen 31 divides the inside of the feed port 2 into a dust suction chamber and a material discharge chamber, and a negative pressure fan 32 connected to the dust suction chamber is fixedly installed outside the feed port 2;
[0025] With the above-mentioned structural arrangement, the grain is poured in from the feed port 2 and the negative pressure fan 32 is started at the same time. When the grain slides down the inclined surface of the filter screen 31 , the smaller and lighter impurities inside the grain leak through the filter screen 31 and are sucked away and collected by the negative pressure fan 32 .
[0026] Reference Figure 2-4 The sieve body 5 comprises a placing net 51, the placing net 51 is fixedly installed at the bottom of the sieve body 5, a partition plate 52 located at the top of the placing net 51 is fixedly installed inside the sieve body 5, a sieve 53 located at the top of the partition plate 52 is fixedly installed inside the sieve body 5, and the gap between the placing net 51 and the sieve 53 is divided into a plurality of small spaces by the partition plate 52, and a plurality of elastic balls 54 are placed inside the plurality of small spaces;
[0027] Through the above-mentioned structural setting, the size of the mesh of each layer of the screen 53 is different. The falling grain is screened by the multiple layers of the screen 53 and the grain is divided into different grades. During the screening process, the elastic ball 54 bounces continuously in the small space separated by the partition plate 52 as the mounting frame 4 shakes, and continuously hits the screen 53, so that the dust attached to the screen 53 floats up, and at the same time, the grain on the screen 53 is dispersed due to the vibration generated by the impact, thereby enhancing the screening effect of the grain.
[0028] Working principle:
[0029] The first step to implement the innovation point:
[0030] The first step: pour the grain from the feed port 2, and start the negative pressure fan 32 at the same time. When the grain slides down the inclined surface of the filter screen 31, the smaller and lighter impurities inside the grain will leak from the filter screen 31 and be sucked away and collected by the negative pressure fan 32. At the same time, start the reduction motor 61, and the reduction motor 61 drives the rotating rod 62 to rotate. The rotating rod 62 drives the rotating disk 9 to rotate slowly in the guide rail assembly 8. During the rotation process, the rotating disk 9 is moved to the position and lifted up, so that the mounting frame 4 shakes slightly with the rotating disk 9, and the grain inside the screen 53 also shakes with the shaking of the mounting frame 4. The elastic balls 54 also collide with the partition plate 52 and each other as they shake, bouncing and hitting the screen 53, and at the same time, the grain on the screen 53 is scattered due to the vibration generated by the impact, which helps to enhance the screening effect. The fallen grain is screened by the multi-layer screen 53 and divided into different grades. After the screening is completed, the grain in the screen 53 is taken out and collected. After the grain is taken out, the impact of the elastic balls 54 will vibrate the dust attached to the screen 53 and then be sucked away by the negative pressure fan 32, making the screen 53 clean.
