[0002] Currently, during the rice processing, rice hulled by a rice huller contains a large amount of bran and dust and other impurities. At this point, a rice-brown rice separator is needed to separate the rice from the bran. In the rice production and processing process, the separation of brown rice and husk after hulling is very important. If the brown rice and husk are not completely separated, and the brown rice is directly processed in the next step, it will affect the subsequent processing effect and is not conducive to ensuring the quality of the finished rice. Therefore, it is very necessary to carry out rice-brown rice separation.
[0003] Existing paddy rice separators mostly use open-top separators for separating paddy rice. When the separator vibrates during separation, it easily generates a large amount of dust. Existing paddy rice separators are unable to reduce dust generation, resulting in pollution and harm to the environment and operators. They are also unable to reduce the impact of dust and impurities in paddy rice on the quality and purity of the paddy rice.
[0004] To address the aforementioned technical deficiencies, a solution is proposed. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] This embodiment addresses the problem that existing rice-rice separators struggle to reduce dust generation, leading to pollution and harm to the environment and operators, and that dust and impurities in rice negatively impact its quality and purity.
[0026] Please see Figures 1-5 As shown, this embodiment is a rice and husk separator with dust suppression function, including a separation box body 1, a feeding hopper 2 fixedly connected to one side of the upper surface of the separation box body 1, a blade 17 rotatably connected inside the feeding hopper 2, an opening at the top of the separation box body 1, a sealing plate 5 fixedly connected to the opening at the top of the separation box body 1, and a dust suppression mechanism provided on the separation box body 1.
[0027] 4. The dust removal mechanism includes a dust removal pipe 4 that communicates with the feed hopper 2 and the separation box body 1. A collection hopper 6 is connected through the end of the dust removal pipe 4 near the sealing plate 5. A collection cylinder 8 is fixedly connected to the outer wall of the separation box body 1. A fan 14 is fixedly installed at the end of the collection cylinder 8 near the feed hopper 2. A connecting pipe 7 is connected through the outer contour of the collection cylinder 8. The end of the connecting pipe 7 away from the collection cylinder 8 is connected to the dust removal pipe 4.
[0028] Rice grains containing brown rice and husks are placed into the feed hopper 2. The two ends of the dust removal pipe 4 are connected to the feed hopper 2 and the separation box body 1. The fan 14, which is fixed on one side of the collection cylinder 8, is started. When the blade 17 rotates, the fan 14 sucks the dust generated in the feed hopper 2 into the connecting pipe 7 through the dust removal pipe 4. This can separate the rice grains in the separation box body 1 and suck the separated dust into the collection hopper 6. The dust then enters the collection cylinder 8 through the dust removal pipe 4 and the connecting pipe 7 for centralized processing. This can effectively reduce the dust generated in the separation box body 1 during screening, prevent dust from escaping, reduce the clogging and blockage of the equipment by the husks, improve processing efficiency, and effectively remove dust, impurities, and husks from the rice, thereby improving the quality and purity of the rice.
[0029] A motor 13 is fixedly connected to the outer wall of the separator body 1. The output end of the motor 13 passes through the feed hopper 2 and is fixedly connected to the blade 17. The feed hopper 2 has an arc-shaped inner wall that fits against the blade 17. When the motor 13 on the outer wall of the feed hopper 2 is started, the motor 13 rotates and drives the blade 17 to rotate. The rotation of the blade 17 can agitate the grain in the feed hopper 2, thereby realizing automatic feeding. A cover plate 3 is provided at the opening of the feed hopper 2. The cover plate 3 is rotatably connected to the feed hopper 2 through a rotating shaft. Rotating the cover plate 3 closes the opening of the feed hopper 2 to prevent the dust generated by the blade 17 agitating the grain from spreading when it rotates, which can further reduce dust during grain separation.
[0030] The separation box body 1 is vertically spaced with multiple screening plates 19 for separating grains, and the outer wall of the separation box body 1 is fixedly connected with multiple discharge ports 9 corresponding to the screening plates 19; the screening plates 19 and discharge ports 9 work together to effectively separate the grains and husks, and the multiple discharge ports 9 discharge brown rice and husks separately.
[0031] A base 10 is provided at the bottom of the separator body 1. A connecting sleeve 11 is fixedly connected to the upper surface of the base 10 and the lower surface of the separator body 1. A spring 12 is provided between the two connecting sleeves 11. A motor 3 18 is fixedly installed at the bottom of the separator body 1. When the motor 3 18 located on the lower surface of the separator body 1 is started, the motor 3 18 is a vibrating motor. The vibrating motor causes the separator body 1 to shake. The grain in the feed hopper 2 falls into the screen plate 19. The vibration of the screen plate 19 on the screen surface separates the brown rice and the husk. The larger brown rice falls into the lower part of the separator through the holes, while the husk is screened to the upper part due to the larger holes. The separated brown rice is collected through the corresponding discharge port 9, while the husk is discharged from the corresponding discharge port 9 of the machine.
[0032] Example 2:
[0033] This embodiment is used to solve the problem of centralized processing of collected dust.
[0034] Please see Figure 1 , Figure 5 As shown, the grain separator with dust reduction function in this embodiment includes a collection cylinder 8 with a motor 16 fixedly installed at the end away from the fan 14, a discharge port 15 opened at the end of the collection cylinder 8 near the motor 16, a spiral feeding rod 21 fixedly connected to the shaft end of the motor 16 and rotatably connected to the collection cylinder 8, and a filter screen 20 provided at the end of the collection cylinder 8 near the fan 14.
[0035] The collecting cylinder 8 is tilted towards the end closest to the motor 16. When the motor 16 is started, it rotates and drives the screw feed rod 21 to rotate, which can move the dust adsorbed in the collecting cylinder 8 to the discharge port 15 and discharge it, thus effectively controlling the automatic discharge of dust.
[0036] Combining Example 1 and Example 2
[0037] By setting up a dust suppression mechanism, the dust removal pipe 4 can adsorb and treat the dust generated during feeding into the feed hopper 2 while feeding into the feed hopper 2, reducing the dust generated during feeding. At the same time, the dust generated during separation in the separation box 1 is treated by the collection hopper 6, reducing dust dispersion, reducing the jamming and blockage of the equipment by rice husks, improving processing efficiency, and effectively removing dust, impurities and rice husks from the rice, improving the quality and purity of the rice. Meanwhile, by setting up a motor 16 to rotate and drive the screw feed rod 21 to rotate, the dust adsorbed in the collection cylinder 8 can be moved to the discharge port 15 and discharged, effectively controlling the automatic discharge of dust and facilitating the centralized collection of the collected dust.
[0038] like Figures 1-5 As shown, the working process and principle of this utility model are as follows:
[0039] Step 1: Start the motor 13 on the outer wall of the feed hopper 2. The motor 13 rotates and drives the blade 17 to rotate. The rotation of the blade 17 can move the grain in the feed hopper 2, thereby realizing automatic feeding. Start the motor 3 18 located on the lower surface of the separator body 1. The motor 3 18 makes the separator body 1 shake. The grain in the feed hopper 2 falls into the screen plate 19. The vibration of the screen plate 19 on the screen surface separates the brown rice and the husk. The larger brown rice falls into the lower part of the separator through the holes, while the husk is screened to the upper part due to the larger holes. The separated brown rice is collected through the corresponding discharge port 9, while the husk is discharged from the corresponding discharge port 9 of the machine.
[0040] Step 2: Start the fan 14 fixed on one side of the collection cylinder 8. The fan 14 sucks the dust generated in the feed hopper 2 into the connecting pipe 7 through the dust removal pipe 4. While separating the grain in the separation box body 1, the fan 14 sucks the separated dust into the collection hopper 6 and into the collection cylinder 8 through the dust removal pipe 4 and the connecting pipe 7. Start the motor 16. The motor 16 rotates and drives the screw feed rod 21 to rotate. This moves the dust adsorbed in the collection cylinder 8 to the discharge port 15 and discharges it.
