[0002] Rice is a kind of herbaceous rice, belonging to the cereal family. It is also the most important and oldest type of food in the rice genus, different from upland rice. It is native to China and India. Rice was planted in the Yangtze River Basin of China 7,000 years ago. The fruit of rice is paddy. After the husk of paddy is removed, it is called brown rice. The rice is ground to remove the bran layer. Nearly half of the world's population eats rice. In addition to being edible, rice can also be used as industrial raw materials for brewing and making sugar. Rice husks and rice straw can be used as feed. The main rice producing areas in my country are mainly the Northeast, the Yangtze River Basin, and the Pearl River Basin. It is a direct cash crop, the staple food of one-third of the world's population, and the main organic food for people in the north. With the development of the economy and the need for large-scale agricultural production, the requirements for the level of agricultural mechanization are getting higher and higher.
[0003] Rice refers to the rice grain without removing the husk. Botanically, it belongs to the Oryza subspecies of the Oryza subgenus of the Gramineae family. Humans have confirmed a total of 22 types of rice, but the only one used in bulk trade is the common rice.
[0004] The existing technology has the following problems:
[0005] 1. The existing rice grain screening equipment based on rice processing has few screening methods, and the screened rice grains contain rice ash, which is not clean enough and needs to be screened again later. The device is not convenient to use;
[0006] 2. The existing rice grain screening equipment based on rice processing does not screen clearly enough and does not screen by particle size, which makes the efficiency of particle screening low. The screening method will also cause internal blockage and inconvenience in operation. Utility Model Content

The leakage holes of the screening net of the bottom layer are smaller than those of the previous group, so that smaller particles can be screened. Broken particles are discharged through the middle part of the base, so that the screening of the device is clearer. BRIEF DESCRIPTION OF THE DRAWINGS

Rice particles are put into the input port 3 at the top of the cylinder 1. Dust will be generated during the entry process. The dust gathers inside the cylinder 1 and is then sucked in through the shelling mechanism 4, thereby reducing the internal dust. The internal particles are discharged from the residue for the next step of screening and differentiation, making the device more convenient to use.

[0028] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the shell discharge mechanism 4 includes a vacuum cleaner 41, the outer wall of the vacuum cleaner 41 passes through the outer wall of the cylinder 1, the interior of the vacuum cleaner 41 is fixedly connected with a through pipe 42, one side of the through pipe 42 is fixedly connected with an ash box 43, and one side of the vacuum cleaner 41 is fixedly connected with a suction port 44.
[0029] In this embodiment, through the joint action of the vacuum cleaner 41, the through pipe 42, the ash box 43 and the suction port 44, the device can be made more convenient to use. After the vacuum cleaner 41 is started, the dust inside the cylinder 1 is affected by the suction force and enters from the inside of the suction port 44, and then is transported to the inside of the ash box 43 by the through pipe 42. After the inside of the ash box 43 is full, it can be taken out by pulling one side, making the device more convenient to use.
[0030] Example 3
[0031] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, two groups of screening devices 8 are installed inside the cylinder 1, and the screening devices 8 are installed in an inclined shape, and a group of branch pipes 5 at each level corresponds to the oblique lower side of the two groups of screening devices 8.
[0032] The screening device 8 includes a connecting slot 81, the outer wall of the connecting slot 81 is fixedly connected to the inner wall of the cylinder 1, the inner wall of the slot is fixedly connected to a driving box 82, one side of the driving box 82 is transmission-connected to a telescopic rod 83, one end of the telescopic rod 83 is fixedly connected to a connecting ring 84, and a screening net 85 is installed in the inner middle part of the connecting ring 84.
[0033] There are two sets of drive boxes 82 installed on opposite sides of the connecting slot 81 , and the directions in which the two sets of drive boxes 82 pull the connecting ring 84 are inconsistent.
[0034] In this embodiment, the screening device 8 and the various levels of branch pipes 5 work together to make the device more convenient to use. The screening device 8 is connected to the inner wall of the cylinder 1 through the connecting card slot 81. The connections are tight at all places and the rice particles will not be integrated into the top of the next layer of screening. The inside of the connecting card slot 81 pulls the telescopic rod 83 to move left and right through the driving box 82, so that the device can shake in the form of a sieve, which is convenient for the rice particles to enter the bottom. At the same time, the device moves left and right to generate vibration, which can make the connected screening net 85 or the accumulated particles shake and disperse. The leakage hole size of each group of the screening net 85 is different. The top is larger, which can screen out the rice particles with larger particles, and then discharge them through the various levels of branch pipes 5. The leakage hole size of the bottom layer of the screening net 85 is smaller than that of the previous group, which can screen out the smaller particles. For the broken particles, they are discharged through the middle part of the base 6, making the device more convenient to use.

[0038] The following is a detailed description of the working principle of the rice grain screening equipment based on rice processing.
[0039] like Figure 1-4As shown, when this rice grain screening device based on rice processing is in use, rice grains are put in from the input port 3 at the top of the cylinder 1. Dust will be generated during the entry process. The dust gathers inside the cylinder 1 and is then sucked in through the shell discharging mechanism 4, so that the internal dust is reduced, and the internal grains are discharged from the residue for the next step of screening and differentiation, making the device more convenient to use. After the vacuum cleaner 41 is started, the dust inside the cylinder 1 is affected by the suction force and enters from the inside of the suction port 44, and is then transported to the inside of the ash box 43 by the through pipe 42. After the inside of the ash box 43 is full, it can be taken out by pulling one side, making the device more convenient to use. The screening device 8 is connected to the inner wall of the cylinder 1 through the connecting card slot 81. The connections are tightly connected everywhere, so that the rice grains will not be integrated into the top of the next layer of screening. The inside of the card slot 81 is moved left and right by pulling the telescopic rod 83 through the driving box 82, which can make the device shake in the form of a sieve, making it convenient for rice particles to enter the bottom. At the same time, the device moves left and right to generate vibration, which can make the card-connected screening net 85 or the accumulated particles shake and scatter. The leakage hole size of each group of screening nets 85 is different. The top is larger, which can screen out rice particles with relatively large particles, and then discharge them through the branch pipes 5 at each level. The leakage hole size of the screening net 85 of the bottom layer is smaller than that of the previous group, which can screen out relatively small particles. For broken particles, they are discharged through the middle part of the base 6, making the device more convenient to use. The bottom of the base 6 can control the discharge of particles that do not meet the standards through the regulating valve 62, and the connecting tube 63 can collect the defective particles, making the later discharge more convenient.
