[0002] Unpolished rice is unpolished rice grains that are formed due to mechanical damage to the rice grains. During the polished rice processing, it is usually necessary to pick out the unpolished rice grains to avoid affecting the quality of the polished rice product.

[0003] Authorization publication number "CN221183642U" records "a rice grain outside brown rice grading and screening device". The utility model relates to a rice grain outside brown rice grading and screening device, including a first-level screening box and a mounting frame. The bottom of the first-level screening box is fixedly connected to a second-level screening box. The first-level screening box is provided with a first-level screening assembly, and the second-level screening box is provided with a second-level screening assembly. The rice grain outside brown rice grading and screening device is able to achieve the effect of grading and screening by providing a first-level screening box and a second-level screening box and providing a first-level screening assembly and a second-level screening assembly inside the first-level screening box. The first-level screening assembly is used to screen the rice grain outside brown rice with fuller grains and better appearance. The second-level brown rice with secondary appearance can achieve the effect of secondary screening under the action of the second-level screening assembly, thereby effectively ensuring the effect of grading and screening the rice grain outside brown rice. A transmission motor is provided at the bottom of the mounting frame. Under the transmission action of the transmission motor, the material guide assembly can achieve a good material guide effect.

[0004] The above patent can solve the problem that the brown rice outside the grain with fuller grains and better appearance can be screened once by the first-level screening component, and the brown rice outside the grain with secondary appearance can be screened twice by the second-level screening component, thereby effectively ensuring the effect of graded screening of the brown rice outside the grain. A transmission motor is provided at the bottom of the mounting frame. Under the transmission action of the transmission motor, the material guide component can play a good material guiding effect. However, if the traditional rice screening equipment is not equipped with a cleaning structure to regularly clean the filter disc, a series of problems will arise. The filter disc is the core component of the dust collection function, and its function is to block and capture dust and impurities in the air. However, if the filter disc is not cleaned for a long time, dust and impurities will gradually accumulate and clog the filter holes, thereby hindering air circulation and eventually causing a significant reduction in dust removal efficiency.

[0030] Example

[0031] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0032] A rice screening device with a dust suction function comprises:

[0033] Rice screening device 1;

[0034] The cleaning mechanism is arranged at the rear side of the rice screening device 1.

The filter 5 is fixedly connected to the rice screening device 1, and the two cleaning rods 4 are respectively arranged on both sides of the filter 5.

[0035] In a specific embodiment of the present invention, a rice screening device with a dust suction function includes a rice screening device 1 and a cleaning mechanism. The cleaning mechanism is arranged at the rear side of the rice screening device 1. The cleaning mechanism includes a dust suction and purification device 2, a drive shaft 3, two cleaning rods 4 and a filter 5. The dust suction and purification device 2 is fixedly connected to the rear end of the rice screening device 1, and the drive shaft 3 is rotatably connected to the dust suction and purification device 2. The two cleaning rods 4 are fixedly connected to the circumferential surface of the drive shaft 3. A filter 5 is fixed in the rice screening device 1, and the two cleaning rods 4 are respectively arranged on both sides of the filter 5. When the drive shaft 3 rotates, the cleaning rod 4 rotates accordingly and cleans both sides of the filter 5. The dust suction and purification device 2 collects the dust and impurities swept down by suction. This structural design can effectively remove the residue on the filter 5, avoid blockage, and improve screening efficiency and cleanliness.

[0036] For details, please refer to Figure 1-Figure 4 A centrifugal fan 6 is fixedly connected to the circumferential surface of the driving shaft 3 , and a centrifugal fan 6 is provided in the dust collection and purification equipment 2 .

[0037] In this embodiment: the circumferential surface of the drive shaft 3 is fixedly connected to a centrifugal fan 6, and the centrifugal fan 6 is arranged in the dust collection and purification device 2. When the drive shaft 3 rotates, the centrifugal fan 6 is driven to rotate together, generating suction, and the dust and impurities swept down by the cleaning rod 4 are sucked into the dust collection and purification device 2. The rotation of the centrifugal fan 6 not only helps to collect impurities, but also promotes air circulation, thereby ensuring the dust collection effect.

[0038] For details, please refer to Figure 1-Figure 4 The front end of the dust suction and purification equipment 2 is fixedly connected with an air intake port 7, and the two side ends of the dust suction and purification equipment 2 are respectively fixedly connected with two limit supports 8, and the rear end of the rice screening device 1 is fixedly connected with two limit supports 8.

[0039] In this embodiment: the front end of the dust suction and purification equipment 2 is fixedly connected with an air intake port 7, and the two side ends of the dust suction and purification equipment 2 are respectively fixedly connected with two limit supports 8, and the rear end of the rice screening device 1 is also fixedly connected with two limit supports 8. Through the connection of the limit supports 8, it is ensured that the dust suction and purification equipment 2 and the rice screening device 1 are firmly combined together. When the drive shaft 3 rotates, it drives the centrifugal fan 6 to rotate to generate suction, and the dust and impurities generated during the rice screening process are sucked into the dust suction and purification equipment 2 through the air intake port 7 for purification.

[0040] For details, please refer to Figure 1-Figure 4 The lower end of the dust collection and purification device 2 is rotatably connected to a dust receiver 9.

[0041] In this embodiment: the lower end of the dust collection and purification device 2 is rotatably connected to the dust receiver 9. When the centrifugal fan 6 is running, the dust and impurities sucked in through the air intake 7 are guided into the dust collection and purification device 2, and after being filtered by the filter 5, they are collected in the dust receiver 9 below.

[0042] For details, please refer to Figure 1-Figure 4 The lower end of the rice screening device 1 is fixedly connected to two base frames 10, and the upper end of the rice screening device 1 is fixedly connected to a feeding port 11.

[0043] In this embodiment: the lower end of the rice screening device 1 is fixedly connected to two base frames 10, which provide stable support for the entire device; the upper end of the rice screening device 1 is fixedly connected to a feed port 11, through which the rice to be screened is fed into the screening device.

[0044] For details, please refer to Figure 1-Figure 4 Two connecting rods 12 are provided on the lower side of the rice screening device 1, and the two side ends of the two connecting rods 12 are fixedly connected to two base frames 10 respectively.

[0045] In this embodiment, two connecting rods 12 are provided on the lower side of the rice screening device 1. The two side ends of the two connecting rods 12 are fixedly connected to two base frames 10 respectively. The base frames 10 and the rice screening device 1 are firmly connected by the connecting rods 12, thereby ensuring the stability and support strength of the entire device.

[0046] For details, please refer to Figure 1-Figure 4 The front end of the rice screening device 1 is fixedly connected to a first screening outlet 13 , the front end of the rice screening device 1 is fixedly connected to a second screening outlet 14 , and the front end of the rice screening device 1 is fixedly connected to a third screening outlet 15 .

[0047] In this embodiment, the front end of the rice screening device 1 is fixedly connected to a first screening outlet 13, a second screening outlet 14 and a third screening outlet 15. Through these three screening outlets of different sizes, the screened rice is discharged separately according to the particle size. The advantage of this design is that it can classify rice according to different particle sizes, thereby improving screening efficiency and screening accuracy.

[0048] The working principle and use process of the utility model are as follows: first, the rice is fed into the screening device through the feeding port 11 located at the upper end of the rice screening device 1. Then, the screening device starts to work, and the rice is screened inside and discharged from the first screening outlet 13, the second screening outlet 14 and the third screening outlet 15 according to the particle size. At the same time, the driving shaft 3 rotates under the drive of the motor or other power source, driving the two cleaning rods 4 to rotate around the driving shaft 3. The cleaning rods 4 clean the residues on both sides of the filter 5. The centrifugal fan 6 generates suction as the driving shaft 3 rotates, and the dust and impurities swept down are sucked in through the air intake 7 at the front end of the dust cleaning device 2. After being filtered by the filter 5, these dust and impurities fall into the lower end of the dust cleaning device 2. The dust is collected in the dust receiver 9, and the entire device is kept stable by the support provided by the base frame 10 and the connecting rod 12. The limit support 8 ensures a firm connection between the dust collection and purification device 2 and the rice screening device 1. This process ensures the efficiency, cleanliness and quality of the screening results during the screening process. By using this device, a series of problems will be caused if the traditional rice screening equipment does not add a cleaning structure to regularly clean the filter. The filter is the core component of the dust collection function, and its function is to block and capture dust and impurities in the air. However, if the filter is not cleaned for a long time, dust and impurities will gradually accumulate and clog the filter holes, thereby hindering air circulation and eventually causing a significant reduction in dust removal efficiency.
