[0016] 3.

DETAILED DESCRIPTION

[0020] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Embodiment 1: The present invention provides a technical solution: Referring to Figure 1 - Fig.13The present invention discloses a rice processing rice roughness separation device, comprising a shell 1 fixedly mounted on a supporting leg, and further comprising: the front view shape of the shell 1 is a T-shaped arrangement, a separation assembly 2 is arranged in the shell 1, and the separation assembly 2 includes a storage cylinder 21, the storage cylinder 21 is arranged in the top opening of the shell 1, and the outer peripheral wall of the storage cylinder 21 is gap-matched with the inner wall of the top opening of the shell 1, the top of the shell 1 is located above the top of the storage cylinder 21, and a turntable 22 is rotatably arranged in the top opening of the storage cylinder 21 through a bearing , and the turntable 22 is provided with densely distributed fine holes, an air pump 23 is fixedly installed at the center position of the inner bottom wall of the storage cylinder 21, and the bottom end opening of the air pump 23 is fixedly penetrated through the cylinder wall of the storage cylinder 21, a filter plate 24 is fixedly installed through the outer peripheral wall of the bottom of the shell 1, and the filter plate 24 is located at the bottom side of the storage cylinder 21, a first annular plate 25 is fixedly installed on the inner bottom wall of the shell 1, and a second annular plate 26 is sleeved on the outer peripheral side of the first annular plate 25, and the bottom side of the second annular plate 26 is fixedly connected to the inner bottom wall of the shell 1; A driving mechanism 3 is provided on the top side of the turntable 22 , a feeding mechanism 4 is provided at the front end of the top side of the turntable 22 , a suction mechanism 5 is provided on the housing 1 , and a filtering mechanism 6 is provided in the storage cylinder 21 .

[0022] In this embodiment, when the improved rice-rough separation device is used, the driving device is first started to drive the turntable 22 to rotate at a constant speed, and at the same time, the air pump 23 is started to continuously extract the gas in the storage tube 21, so that a negative pressure cavity of corresponding strength is formed in the storage tube 21, and at the same time, the extracted gas is injected into the storage tube 21, so that a high-pressure cavity is formed at the bottom of the shell 1, so that high-pressure cavities are formed inside and outside the shell 1. At this time, the excess gas at the bottom of the shell 1 flows upward and is discharged from the gap between the storage tube 21 and the inner wall of the top opening of the shell 1, and the excess gas at the bottom of the storage tube 21 passes through the holes of the filter plate 24 and is discharged to the outer peripheral side of the shell 1. After the above device is started, the feeding mechanism 4 starts to scatter the raw materials at the corresponding positions on the turntable 22 at a uniform speed. At this time, due to the adsorption effect of the negative pressure chamber in the storage cylinder 21 on the raw materials, the brown rice, rice grains, rice husks and particulate debris in the raw materials are adsorbed on the top side of the turntable 22. At this time, since the surface roughness of the rice grains is much greater than the surface roughness of the brown rice, the friction between the rice grains and the turntable 22 is much smaller than the friction between the rice grains and the turntable 22. In the process of the raw materials following the turntable 22, due to the action of centrifugal force, the brown rice slides off the turntable 22, and then The rice, rice husk and granular debris fall into the outer shell 1 through the gap between the storage cylinder 21 and the inner wall of the top opening of the outer shell 1. At the same time, due to the large friction between the rice, rice husk and granular debris and the turntable 22, the centrifugal force cannot pull the rice, rice husk and granular debris to slide on the turntable 22, so that the rice, rice husk and granular debris are relatively stably adsorbed on the turntable 22 and rotate with the turntable 22, which can greatly avoid the mutual friction between the brown rice and foreign objects and the brown rice, thereby avoiding the damage of the brown rice surface to affect the aesthetics of the finished brown rice, and avoiding the brown rice part from being ground into rice flour, resulting in unnecessary waste of products; When the brown rice moves to the bottom side of the storage cylinder 21, due to the push of the lateral airflow, the larger grains of brown rice fall between the first annular plate 25 and the second annular plate 26, while the broken rice in the brown rice falls between the second annular plate 26 and the inner wall of the housing 1, so as to classify and store the fallen brown rice, thereby preventing a large amount of broken rice from being mixed into the finished brown rice product and affecting the quality of the brown rice; It should be noted that when the brown rice falls, the upward gas pushes the brown rice, which can slow down the falling speed of the brown rice in terms of movement, so as to leave time for the lateral movement of the brown rice. In the process that the rice, rice husks and granular debris follow the rotation of the turntable 22, when the rice, rice husks and granular debris move to the bottom of the suction mechanism 5, due to the push of the gas on the rice, rice husks and granular debris, the airflow carries the rice, rice husks and granular debris together, and the rice is directly intercepted and stored in the suction mechanism 5, while the rice husks and granular debris are brought into the storage cylinder 21 by the airflow, and then the rice husks and granular debris are intercepted by the filtering mechanism 6 and stored in the storage cylinder 21. The operator can directly take out the rice from the suction mechanism 5 and re-perform the rice husking operation, and the operator does not need to pick out or sift out the rice from the debris, thereby reducing the workload of the staff.

[0023] In a further preferred embodiment of the present invention, Figure 1 and Figure 8As shown, the driving mechanism 3 includes a support plate 31 in a U-shape, the support plate 31 is fixedly sleeved on the top of the housing 1, a driving rod 32 is fixedly installed at the center position of the top side of the turntable 22, and the driving rod 32 is rotatably connected to the support plate 31 through a rotating shaft and a bearing, a gear ring 33 is fixedly installed on the top side of the driving rod 32, a motor 34 is fixedly installed on the support plate 31, and the driving end of the motor 34 rotates through the plate wall of the support plate 31, and a gear 35 is fixedly installed on the driving end of the motor 34, and the gear 35 is meshed with the gear ring 33; In this embodiment, when the driving mechanism 3 drives the turntable 22 to rotate, the motor 34 drives the gear 35 to rotate. Due to the meshing of the gear 35 and the gear ring 33, the started motor 34 drives the driving rod 32 to rotate at a rated speed, thereby driving the turntable 22 to rotate synchronously and at a uniform speed. Since the diameter of the gear ring 33 is larger than the diameter of the gear 35, the driving force of the motor 34 driving the turntable 22 to rotate can be greatly enhanced.

[0024] In a further preferred embodiment of the present invention, Figure 1 , Fig.11 and Fig.12 As shown, the feeding mechanism 4 includes a feeding pipe 41, which is arranged at the front end of the top side of the turntable 22, and the top of the feeding pipe 41 is fixedly penetrated through the plate wall of the support plate 31, the rear side of the feeding pipe 41 is in contact with the outer peripheral wall of the driving rod 32, and the front side of the feeding pipe 41 is fixedly penetrated with a spiral feeder 42, and the spiral feeder 42 slides through the plate wall of the support plate 31, and the bottom side opening end of the feeding pipe 41 is in contact with the top side of the turntable 22; In this embodiment, during the rotation of the above-mentioned turntable 22, the spiral feeder 42 starts to push the corresponding amount of raw materials into the feed pipe 41 at a uniform speed, and then the raw materials fall due to their own gravity. After the raw materials come into contact with the turntable 22, the raw materials are scattered around due to the reaction force when colliding with the turntable 22, and due to the obstruction of the feed pipe 41, the raw materials are completely scattered on the turntable 22, so as to avoid the excessive density on the turntable 22, which causes the brown rice sliding on the turntable 22 to slide off the turntable 22 together with the rice grains; It should be noted that the feed end of the screw feeder 42 is connected to the discharge end of the external raw material supply device through a feed pipe. At this time, due to the supply of the external raw material device, a corresponding amount of raw materials is always stored in the storage hopper of the screw feeder 42.

[0025] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 and Figure 7 As shown, a plurality of support rods 27 are fixedly mounted on the top side of the first annular plate 25 in a circumferential array, and the top end of each support rod 27 is fixedly connected to the bottom side of the storage cylinder 21; In this embodiment, the support rod 27 can stably support the storage cylinder 21 at various positions on the bottom side of the storage cylinder 21, so that the position of the storage cylinder 21 in the top opening of the shell 1 remains stable, and the setting of the support rod 27 will hardly affect the flow of the exhaust gas from the air pump 23 toward the filter plate 24.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 7 As shown, a soft plate 28 is fixedly mounted on the inner arc wall of the filter plate 24 and the inner wall of the housing 1, and the portion of the soft plate 28 located on the filter plate 24 is arranged in a mesh shape, and honeycomb-shaped holes are opened in the plate wall of the soft plate 28; In the present embodiment, when the above-mentioned part of the broken rice falls between the second annular plate 26 and the inner wall of the outer shell 1, the part of the broken rice with extremely small volume will collide with the soft plate 28 during the process of moving toward the inner wall of the outer shell 1, and then the impact force of the broken rice is offset by the expansion and contraction deformation of the plate wall of the soft plate 28, so that the broken rice can directly fall between the second annular plate 26 and the inner wall of the outer shell 1, avoiding a strong collision between the broken rice and the harder inner wall of the outer shell 1, which may cause the broken rice to be damaged, and at the same time avoiding a large rebound force generated after the collision between the broken rice and the harder inner wall of the outer shell 1, which may cause the broken rice to directly rebound and fall between the first annular plate 25 and the second annular plate 26.

[0027] In a further preferred embodiment of the present invention, Figure 2 - Figure 7 As shown, a first magnetic scraper 29 is provided between the outer ring wall of the second annular plate 26 and the inner wall of the outer shell 1, and the outer wall of the first magnetic scraper 29 contacts the inner wall of the outer shell 1 and the outer peripheral wall of the second annular plate 26, a second magnetic scraper 210 is provided between the outer ring wall of the first annular plate 25 and the inner ring wall of the second annular plate 26, and the outer wall of the second magnetic scraper 210 contacts the inner wall of the outer shell 1, the outer ring wall of the first annular plate 25 and the inner ring wall of the second annular plate 26, a magnetic plate 211 is slidably installed at the position of the first magnetic scraper 29 and the second magnetic scraper 210 on the bottom side of the outer shell 1, an annular groove 212 is opened at the position of the magnetic plate 211 on the bottom side of the outer shell 1, and a ball 213 is rotatably installed in the annular groove 212, and the ball 213 is rotatably connected to the magnetic plate 211 through a connecting rod and a bearing; In this embodiment, after the above-mentioned raw material grain-brown separation operation is completed, the operator pushes the magnetic plate 211 to make a circular motion, thereby driving the first magnetic plate 211 and the second magnetic plate 211 to make a circular motion synchronously through the magnetic adsorption force between the magnetic plate 211 and the first magnetic plate 211 and the second magnetic plate 211, and finally pushing the brown rice and broken rice toward the discharge hole, so that the brown rice and broken rice pass through the discharge hole and slide out of the housing 1; During the rotation of the magnetic plate 211, the ball 213 is synchronously located and rolled in the annular groove 212. At this time, due to the mutual interference between the ball 213 and the inner wall of the annular groove 212, a restraining force can be applied to the moving magnetic plate 211, so that the magnetic plate 211 slides in an annular track, and the rotation of the ball 213 can greatly reduce the resistance encountered by the magnetic plate 211 when sliding; It should be noted that two discharge holes are provided on the bottom side of the housing 1 at positions corresponding to the first annular plate 25 and the second annular plate 26 , and sealing plates are threadedly installed in the two discharge holes.

[0028] In a further preferred embodiment of the present invention, Figure 1 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.13 As shown, the suction mechanism 5 includes a storage box 51, which is fixedly mounted on the left outer wall of the shell 1, a suction pipe 52 is provided at the left end of the top side of the filter plate 24, and the right end of the suction pipe 52 contacts the outer peripheral wall of the driving rod 32, the suction pipe 52 is fixedly connected to the top of the shell 1, and the bottom open end of the suction pipe 52 contacts the top side of the turntable 22, the interior of the suction pipe 52 is connected to the interior of the storage box 51 through a plurality of connecting pipes 53, and a plurality of conduits 54 are fixedly penetrated and installed on the storage box 51, the outer peripheral wall of the storage cylinder 21 and the outer peripheral wall of the shell 1, and the spacing between two adjacent conduits 54 is equal, the left end of the suction pipe 52 is semicircular, and the feeding end of the connecting pipe 53 is coplanar with the inner arc wall of the suction pipe 52, and the discharge end of the connecting pipe 53 is located on the left side of the feeding end of the conduit 54; In the present embodiment, after the above-mentioned particulate impurities, rice husks and rice grains are moved into the suction pipe 52 through the side opening of the suction pipe 52, they are sucked into the storage box 51 together with the airflow due to the push of the airflow. After the airflow and particulate impurities, rice husks and rice grains flow into the storage box 51, the flow rate of the airflow in the storage tube 21 is reduced due to the sudden expansion of the space. At this time, due to the effect of the gravity of the rice grains themselves, the rice grains directly fall to the bottom of the storage box 51 for storage, while the particulate impurities and rice husks, due to their lighter weight, flow directly into the conduit 54 along with the airflow, and are then discharged into the storage tube 21 from the bottom opening of the guide shell 62.

[0029] In a further preferred embodiment of the present invention, Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, a square tube 55 is fixedly installed on the outer peripheral wall of the storage cylinder 21, and the square tube 55 is located on the top side of the guide tube 54, and the square tube 55 is located directly below the suction tube 52. The top open end of the square tube 55 contacts the bottom side of the turntable 22. A plurality of air inlet holes 56 are opened at the left end of the top side of the square tube 55, and the spacing between two adjacent air inlet holes 56 is equal. The interior of the air inlet hole 56 is communicated with the interior of the square tube 55. In this embodiment, during the process of the air pump 23 extracting the gas in the storage cylinder 21, part of the gas in the gap between the storage cylinder 21 and the inner wall of the top opening of the outer shell 1 can flow into the square tube 55 through the air inlet hole 56, and then the gas flows out from the top opening of the square tube 55 and passes through the holes on the turntable 22 and flows into the suction pipe 52, so as to form an airflow from bottom to top at the bottom opening of the suction pipe 52, so that the rice husks and particulate impurities on the turntable 22 can be more easily carried by the airflow and flow into the suction pipe 52.

[0030] In a further preferred embodiment of the present invention, Figure 8 , Fig. 9 and Fig.10 As shown, the filtering mechanism 6 includes two elastic plates 62, a sieve plate 61 with a V-shaped cross-section is provided above the air pump 23, and the front and rear ends of the sieve plate 61 are fixedly connected to the inner wall of the storage cylinder 21, one side of the elastic plate 62 is fixedly connected to the corresponding end of the sieve plate 61, and the other side of the elastic plate 62 is in contact with the inner bottom wall of the storage cylinder 21, and the front and rear ends of the elastic plate 62 are in contact with the inner peripheral wall of the storage cylinder 21, the bottom side of the storage cylinder 21 and the bottom side of the shell 1 are relatively fixedly penetrated by valves 63, and the two valves 63 penetrate the inner hole of the first annular plate 25, a guide shell 64 is provided above the sieve plate 61, and the two ends of the guide shell 64 are fixedly connected to the inner wall of the storage cylinder 21, the bottom side opening end of the guide shell 64 is gap-matched with the sieve plate 61, and the exhaust end of the conduit 54 is fixedly penetrated through the shell wall of the guide shell 64; In the present embodiment, after the rice husks and particulate impurities are sucked into the storage barrel 21, the particulate impurities and rice husks that follow the airflow into the storage barrel 21 are retained and stored in the storage barrel 21 due to the obstruction of the sieve plate 61, while the gas passes through the holes of the sieve plate 61 and is sucked into the air pump 23, thereby preventing the rice husks and particulate impurities from entering the air pump 23 along with the airflow, thereby damaging the air pump 23.

[0031] Working principle: When the improved rice-rough separation device is used, first, the motor 34 drives the driving gear 35 to rotate, thereby driving the turntable 22 to rotate at a rated speed through the gear ring 33 and the driving rod 32, and at the same time, the air pump 23 starts to continuously extract the gas in the storage cylinder 21, so that a negative pressure cavity of corresponding strength is formed in the storage cylinder 21, and at the same time, the extracted gas is injected into the storage cylinder 21, so that a high-pressure cavity is formed at the bottom of the shell 1, and at the same time, part of the gas at the bottom of the storage cylinder 21 flows upward and is discharged from the gap between the storage cylinder 21 and the inner wall of the top opening of the shell 1, and another part of the excess gas at the bottom of the storage cylinder 21 passes through the holes of the soft plate 28 and the filter plate 24 and is discharged to the outer peripheral side of the shell 1; After the negative pressure chamber is formed in the storage cylinder 21, part of the gas on the top side of the turntable 22 flows into the storage cylinder 21 through the holes of the turntable 22 to supplement part of the gas lost in the storage cylinder 21. Meanwhile, another part of the gas on the top side of the turntable 22 flows into the suction pipe 52 from the side opening of the suction pipe 52, and part of the gas in the gap between the storage cylinder 21 and the inner wall of the top opening of the shell 1 flows into the suction pipe 52 through the connecting hole, the square tube 55 and the holes of the turntable 22. Finally, the gas flowing into the suction pipe 52 flows into the storage cylinder 21 through the connecting pipe 53, the storage cylinder 21 and the conduit 54 to supplement another part of the gas lost in the storage cylinder 21. After the above-mentioned device is started, the spiral feeder 42 starts to push the corresponding amount of raw materials into the feed pipe 41 at a uniform speed, and then the raw materials fall due to their own gravity. After the raw materials come into contact with the turntable 22, the raw materials are scattered to the surroundings due to the reaction force when colliding with the turntable 22, and due to the obstruction of the feed pipe 41, the raw materials are completely scattered on the turntable 22, and then with the rotation of the turntable 22, the raw materials are moved out from the side opening of the feed pipe 41, and at this time, due to the adsorption effect of the negative pressure chamber in the storage cylinder 21 on the raw materials, the brown rice and paddy in the raw materials generate corresponding resistance forces with the turntable 22, and at this time, since the surface roughness of the paddy is much greater than the surface roughness of the brown rice, the friction between the paddy and the turntable 22 is much smaller than the friction between the paddy and the turntable 22; It should be noted that due to the friction between the rotating disk 22 and the paddy and brown rice, the rotating rotating disk 22 drives the paddy and brown rice to rotate in a circular trajectory around the driving rod 32; After the rotating turntable 22 passes under the feed pipe 41, a corresponding amount of raw materials will be scattered and laid on the turntable 22, and then the raw materials will rotate together with the turntable 22. Due to the centrifugal force when the rice and brown rice rotate, a pulling force toward the inner wall of the top opening of the shell 1 can be applied to the rice and brown rice. At this time, since the friction between the rice and the turntable 22 is much greater than the centrifugal force, the rice is stably placed on the turntable 22, and the centrifugal force on the brown rice offsets the friction between the brown rice and the turntable 22, so that the brown rice slides toward the inner wall of the top opening of the shell 1, and finally the brown rice slides off the turntable 22, and falls into the shell 1 from the gap between the storage cylinder 21 and the inner wall of the top opening of the shell 1; When the brown rice falls, the brown rice falling rate is reduced due to the push of the upward airflow on the brown rice, and after the brown rice moves to the bottom side of the storage cylinder 21, the brown rice moves toward the filter plate 24 due to the push of the lateral airflow, and the smaller the volume of the brown rice, the faster the lateral movement rate. At this time, the larger particles of brown rice fall between the first annular plate 25 and the second annular plate 26, and the broken rice in the brown rice falls between the second annular plate 26 and the inner wall of the shell 1, so as to classify and store the falling brown rice, and avoid the brown rice finished product being mixed with a large amount of broken rice to affect the quality of the brown rice; It should be noted that when the above-mentioned part of the broken rice falls between the second annular plate 26 and the inner wall of the outer shell 1, the broken rice with a very small volume will collide with the soft plate 28 during the process of moving toward the inner wall of the outer shell 1, and then the impact force of the broken rice is offset by the expansion and contraction deformation of the plate wall of the soft plate 28, so that the broken rice can directly fall between the second annular plate 26 and the inner wall of the outer shell 1, avoiding a strong collision between the broken rice and the harder inner wall of the outer shell 1, which may cause the broken rice to be damaged, and at the same time avoiding a large rebound force generated after the broken rice collides with the harder inner wall of the outer shell 1, causing the broken rice to directly rebound and fall between the first annular plate 25 and the second annular plate 26; During the process of the above-mentioned brown rice being thrown out from the turntable 22, the granular impurities, rice husks and rice grains in the raw material still rotate with the turntable 22 due to the adsorption and fixation of the negative pressure chamber in the storage barrel 21. After the granular impurities, rice husks and rice grains move into the suction pipe 52 from the side opening of the suction pipe 52, they are sucked into the storage box 51 together with the airflow due to the push of the airflow. After the airflow and the granular impurities, rice husks and rice grains flow into the storage box 51, the flow rate of the airflow in the storage barrel 21 is reduced due to the sudden expansion of the space. At this time, due to the effect of the gravity of the rice grains themselves, the rice grains directly fall into the bottom of the storage box 51 for storage, while the granular impurities and rice husks, due to their lighter weight, flow directly into the conduit 54 along with the airflow, and then are discharged into the storage barrel 21 from the bottom opening of the guide shell 62. At this time, due to the obstruction of the sieve plate 61, the granular impurities and rice husks entering the storage barrel 21 with the airflow are retained in the storage barrel 21 for storage, and the gas passes through the holes of the sieve plate 61 and is sucked by the air pump 23; It should be noted that after the airflow in the conduit 54 flows into the guide shell 62, the amount of gas flowing out of the gap between the bottom end of the guide shell 64 and the sieve plate 61 and the amount of gas passing through the holes of the sieve plate 61 are limited, so the gas flowing into the guide shell 62 first fills the guide shell 62, and then forms a pressure difference between the inside and outside of the guide shell 62, so as to accelerate the rate of gas flowing out of the guide shell 62. It should be noted that, since the amount of gas passing through the holes of the sieve plate 61 is limited, part of the gas flowing out of the guide shell 62 passes through the holes of the sieve plate 61 and is sucked by the air pump 23, and the other part of the gas slides along the inclined inner wall of the sieve plate 61, thereby cleaning the inclined outer wall of the sieve plate 61 through the airflow, so that particulate impurities and rice husks will not adhere to the sieve plate 61 for a long time, affecting the use of the sieve plate 61; After the rice-rough separation of the raw materials is completed, the operator removes the cover of the storage box 51, and the rice in the storage cylinder 21 can be directly taken out from the opening of the storage box 51 to perform the rice husking operation again; When taking out the brown rice in the housing 1, the operator first unscrews the sealing plate between the first annular plate 25 and the second annular plate 26, and then places the storage device between the housing 1 and the supporting legs. Then, the operator rotates the magnetic plate 211. Due to the suction between the magnetic plate 211 and the first magnetic scraper 29 and between the magnetic plate 211 and the second magnetic scraper 210, the first magnetic scraper 29 and the second magnetic scraper 210 rotate together with the magnetic plate 211, thereby pushing the brown rice in the housing 1 into the discharge hole, so that the brown rice flows out from the discharge hole at the corresponding position and falls directly into the external storage device for storage; It should be noted that, in the process of taking out the brown rice from the housing 1, the first magnetic scraper 29 and the second magnetic scraper 210 rotate synchronously. Since the amount of broken rice is small, the rotating first magnetic plate 211 pushes the broken rice to slide between the second annular plate 26 and the inner wall of the housing 1. After the brown rice is taken out, the operator screws the disassembled sealing plate back into the discharge hole between the first annular plate 25 and the second annular plate 26, then screws out the sealing plate between the discharge hole between the second annular plate 26 and the inner wall of the housing 1, and places another storage device between the housing 1 and the supporting legs, then rotates the magnetic plate 211 again according to the above, and then pushes the broken rice into the discharge hole through the rotating first magnetic scraper 29, so that the broken rice falls directly from the discharge hole into another storage device for storage; When cleaning the debris in the storage cylinder 21, the operator puts the net bag on the discharge end of the valve 63, then opens the valve 63, and then starts the air pump 23 to continuously extract the gas in the shell 1 and inject the gas into the storage cylinder 21. At this time, a small amount of gas passes through the sieve plate 61 and directly flows into the guide shell 62, and then passes through the conduit 54, the storage box 51, the connecting pipe 53 and the suction pipe 52 to be discharged from the side opening of the suction pipe 52. Another small amount of gas passes through the holes of the sieve plate 61 and the holes of the turntable 22 and is discharged from the storage cylinder 21. At the same time, due to the obstruction of the rotating disk 22, the rice husks and granular impurities will not be discharged from the storage cylinder 21 along with the airflow. At the same time, the last part of the relatively large amount of gas pushes the elastic plate 62 to bend and deform the elastic plate 62, and then the last part of the relatively large amount of gas is quickly discharged from the gap between the elastic plate 62 and the inner bottom wall of the storage cylinder 21, and finally, the rice husks and granular impurities are directly discharged from the valve 63 and flow into the net bag. Due to the interception of the net bag, the rice husks and granular impurities are intercepted and stored in the net bag, while the gas passes through the holes of the net bag and is discharged to the outside. It should be noted that when the air pump 23 extracts the gas at the bottom of the shell 1, the external gas flows into the shell 1 through the gap between the fixed tube and the inner wall of the top opening of the shell 1 and the holes of the mesh plate to replenish the gas lost in the shell 1.

[0032] Embodiment 2: A separation method is obtained according to the above, including the above-mentioned rice processing rice roughness separation device, which specifically includes the following steps: Step 1: The starter motor 34 drives the turntable 22 to rotate at a constant speed through the gear 35, the gear ring 33 and the drive rod 32, and at the same time, the air pump 23 is started to continuously extract the gas in the storage tube 21, so that a negative pressure chamber is formed in the storage tube 21, and the device is started; Step 2: After the device is started, the feeding mechanism 4 starts to feed the raw materials so that the raw materials are scattered on the top side of the turntable 22. At this time, the negative pressure chamber in the storage cylinder 21 can exert an adsorption force on the raw materials, so that the raw materials rotate with the turntable 22. Due to the centrifugal force, the brown rice in the raw materials slides off the turntable 22. Step 3, according to the above steps, the brown rice sliding down from the rotating disk 22 directly falls into the housing 1, while the larger grains of brown rice fall into the space between the first annular plate 25 and the second annular plate 26 for storage, and the broken rice in the brown rice falls into the space between the second annular plate 26 and the inner wall of the housing 1 for storage; Step 4: According to the above steps, the turntable 22 continues to rotate with the rice and rice husk in the raw material. After the rice and rice husk are moved into the suction pipe 52, the rice is sucked into the storage box 51 for storage, and the rice husk is sucked into the storage cylinder 21 for storage. The rice-rough separation operation of the raw material is completed. In this embodiment, the device is easy to operate and has a high degree of automation, which reduces the operator's workload.
