[0002] Rice production and processing is a comprehensive process from rice to the final rice product, which mainly includes rice harvesting, threshing, cleaning, drying, processing, fine grinding and packaging. Through these processes, the rice is husked, polished and graded, and finally converted into white rice suitable for consumers. Among them, after the rice passes through the rice milling section, the broken rice and the impurities contained therein need to be screened, which requires the use of screening equipment, but the existing screening equipment still has some problems in actual use.

[0020] 1. By setting up the first auxiliary screening component, when the turntable rotates driven by the rectangular plate, it can drive the plug disc 1 to move up and down inside the tank body 1. When the plug disc 1 moves upward inside the tank body 1, the antistatic agent inside the liquid storage tank can enter the tank body 1 through the connecting pipe 1. Conversely, when the plug disc 1 moves downward inside the tank body 1, the antistatic agent sucked into the tank body 1 will be squeezed into the infusion tube, and finally sprayed toward the rice pushed out by the material pushing component, which can effectively prevent the problem of static electricity generated between the rice, the rice husk and the impurities.

[0021] 2. By setting up a second auxiliary screening component, during the up and down movement of the L-shaped plate, it can also drive the circular rod to move synchronously, and drive the plug disc 2 to move up and down inside the tank body 2. When the plug disc 2 moves downward inside the tank body 2, the outside air can be sucked into the inside of the tank body 2 through the air intake pipe. Conversely, when the plug disc 2 moves downward inside the tank body 2, the sucked air can be squeezed into the inside of the blowing rack, and blown out through the air outlet groove, and the light hollow rice and broken rice husks in the rice thrown by the guide rack 4 are blown out to the outside of the screening box. On the one hand, the hollow rice can be removed, and on the other hand, the fine rice husks can be effectively prevented from mixing into the subsequent screening operations.

[0022] 3. By setting a material-pickling assembly, when the external frame moves up and down under the rotation of the turntable, it can synchronously drive the L-shaped plate to move up and down inside the positioning plate, and then drive the roller and the mounting shaft to move synchronously. Since the roller is in contact with the bottom surface of the guide frame four, the position of the guide frame four is changed during the up and down movement of the guide frame four, that is, the rice entering the guide frame four can be thrown upward, and then scattered into the screening box under its own gravity, so that the antistatic agent can better contact with the rice, and the antistatic agent can better adhere to the outer surface of the rice, rice husk and debris, thereby improving the antistatic effect and the removal effect of hollow rice and fine debris.

[0037] During operation, in the process of screening the rice, it is only necessary to add the rice to be screened into the interior of the silo 15, and then start the motor 9 by controlling the motor 9 to drive the transmission assembly 16 to operate during the start-up process of the motor 9, and drive the screening box 2 to move back and forth inside the main frame 1 during the operation of the transmission assembly 16, and the motor 9 can move the rice inside the silo 15 to the interior of the screening box 2 for screening during the movement, and the intact rice will enter the interior of the sieve plate 2 4, and finally be introduced into the interior of the rice collecting box 7 through the guide rack 2 6 for collection, and larger impurities and rice husks will be discharged to the outside through the guide rack 1 5, and the broken rice will be discharged to the outside through the guide rack 3 20, thereby realizing effective screening of the rice.

[0038] The transmission assembly 16 includes a rectangular plate 1601, which is fixedly mounted on the other end of the transmission shaft 11. The transmission assembly 16 is used to push the screening box 2;

[0040] During operation, when the motor 9 is started, it can drive the transmission shaft 11 to rotate. When the transmission shaft 11 rotates, the rectangular plate 1601 is rotated. During the rotation of the rectangular plate 1601, the turntable 1602 can be driven to rotate. When the turntable 1602 rotates, the swing plate 1606 can be swung under the action of the connecting plate 1 1604. When swinging, the clamping block 1609 can be driven to move back and forth inside the fixed frame 1608 under the action of the connecting plate 2 1611. Finally, the screening box 2 is driven to move back and forth inside the main frame 1 through the connecting shaft 1612, thereby realizing effective screening of the rice entering the screening box 2.

[0041] The first auxiliary screening assembly 18 includes a tank body 1801 and a liquid storage tank 1802, both of which are fixedly mounted on the top surface of the fixed plate 8. The first auxiliary screening assembly 18 is configured to reduce static electricity between rice and rice husks.

[0042] A connecting pipe 1803 is fixedly connected between the tank body 1801 and the liquid storage tank 1802, a one-way valve 1804 is fixedly installed on the outer surface of the connecting pipe 1803, a plug disc 1809 is internally sealed and clamped, a connecting plate 3 1807 is fixedly installed on the top surface of the plug disc 1809, the other end of the connecting plate 3 1807 is fixedly connected to the bottom surface of the external frame 1603, an infusion tube 1805 is fixedly connected to the outer surface of the tank body 1801, a one-way valve 2 1806 is fixedly installed on the outer surface of the infusion tube 1805, one end of the one-way valve 2 1806 is fixedly connected to a liquid outlet frame 1808, the liquid outlet frame 1808 is fixedly installed on the inner side of the main frame 1 and is located on one side of the material diverting assembly 13, the liquid outlet frame 1808 is inclined, and a plurality of nozzles 1810 are fixedly installed on one side surface of the liquid outlet frame 1808.

[0043] During operation, when the turntable 1602 rotates driven by the rectangular plate 1601, it can drive the external frame 1603 to move up and down under the action of the rectangular plate 1601. When the external frame 1603 moves up and down, it further drives the connecting plate 3 1807 to move up and down, thereby driving the plug disc 1809 to move up and down inside the tank body 1801. When the plug disc 1809 moves upward inside the tank body 1801, the antistatic agent inside the liquid storage tank 1802 can enter the tank body 1801 through the connecting pipe 1803. Conversely, when the plug disc 1809 moves downward inside the tank body 1801, the antistatic agent sucked into the tank body 1801 will be squeezed into the infusion tube 1805, and finally sprayed through the nozzle 1810 toward the rice dialed by the material dialing component 13, which can effectively prevent the problem of static electricity generated between the rice, the rice husk and impurities.

[0044] Through the above, during the rice screening process, the problem of adhesion between rice and rice husks, impurities or between rice and rice due to static electricity can be prevented, thereby achieving the purpose of anti-static electricity and further improving the rice screening effect.

[0045] The material shifting assembly 13 includes a material shifting box 1301, which is fixedly installed inside the main frame 1, a material guide frame 1306 is arranged on one side surface of the material shifting box 1301, a connecting piece 1307 is arranged between the material guide frame 1306 and the material shifting box 1301, and the material guide frame 1306 and the material shifting box 1301 are connected by the connecting piece 1307, an L-shaped plate 1613 is fixedly installed on the top surface of the external frame 1603, and a positioning plate 21 is fixedly installed inside the main frame 1, and the L-shaped plate 1613 is movably connected to the inside of the positioning plate 21. An installation shaft 1614 is fixedly installed inside the L-shaped plate 1613, and rollers 1615 are fixedly installed at both ends of the installation shaft 1614. A plug-in shaft 1302 is rotatably installed inside the material dispensing box 1301, and a pulley 1303 is fixedly installed on one end of the plug-in shaft 1302 and one side surface of the gear 2 12, and a transmission belt 1304 is sleeved between the two pulleys 1303. A material dispensing roller 1305 is fixedly installed on the outer surface of the plug-in shaft 1302 located inside the material dispensing box 1301, and a flat material component 17 is arranged inside the silo 15.

[0046] During operation, when the external frame 1603 moves up and down under the rotation of the turntable 1602, it can synchronously drive the L-shaped plate 1613 to move up and down inside the positioning plate 21, and then drive the roller 1615 and the mounting shaft 1614 to move synchronously. Since the roller 1615 is in contact with the bottom surface of the guide frame four 1306, the position of the guide frame four 1306 is changed during the up and down movement of the guide frame four 1306, that is, the rice entering the guide frame four 1306 can be thrown upwards, and then scattered into the screening box 2 under its own gravity. In this process, the antistatic agent can better contact with the rice, so that the antistatic agent can better adhere to the outer surface of the rice, rice husk and debris, thereby improving the antistatic effect.

[0047] Moreover, in the above process, the pulley 1303 can be driven to rotate when the motor 9 is started, thereby driving the plug-in shaft 1302 to rotate inside the material box 1301 under the action of the transmission belt 1304, and finally driving the material roller 1305 to rotate inside the material box 1301. On the one hand, it can prevent the rice from being blocked during the feeding process, and on the other hand, it can enable the rice to enter the interior of the guide rack four 1306 in batches, so that there will not be too much rice in the interior of the guide rack four 1306 at one time, thereby increasing the scattering effect.

[0048] The second auxiliary screening assembly 19 includes two tank bodies 1901, both of which are installed below the silo 15. The interior of the tank body 1901 is sealed and clamped with a plug plate 1902. The top of the tank body 1901 is fixedly connected with an air inlet pipe 1903, and the outer surface of the air inlet pipe 1903 is fixedly installed with a one-way valve 3 1904. A connecting pipe 2 1905 is fixedly connected to the surface of one side of the tank body 1901, and a one-way valve 4 1906 is fixedly installed on the outer surface of the connecting pipe 1905. One end of the connecting pipe 1905 is fixedly connected to a rectangular tube 1907, and one end of the rectangular tube 1907 is fixedly connected to an air supply pipe 1908. A blowing rack 1909 is provided on one side of the screening box 2. The blowing rack 1909 is a hollow structure. The air supply pipe 1908 is fixedly installed on the outer surface of the connecting pipe 1905. One end of the blowing rack 1909 is fixedly connected to one side surface of the blowing rack 1909, and the other side surface of the blowing rack 1909 is provided with a plurality of air outlet grooves 1912. A circular rod 1913 is fixedly installed on the bottom surface of the plug disc 1902. An extension rod 1616 is fixedly connected to one side surface of the L-shaped plate 1613. A transverse plate 1617 is fixedly installed on one side surface of the extension rod 1616. The bottom end of the circular rod 1913 is fixedly connected to the top surface of the transverse plate 1617. A rotating shaft 1910 is rotatably installed inside the blowing rack 1909. Pulley 1308 is fixedly installed on one end of the rotating shaft 1910 and one end of pulley 1308. A transmission belt 1309 is sleeved between the two pulleys 1308. A fan blade 1911 is fixedly installed on the other end of the rotating shaft 1910.

[0049] During operation, when the L-shaped plate 1613 moves up and down, the circular rod 1913 can also be driven to move synchronously, driving the second plug disc 1902 to move up and down inside the second tank body 1901. When the second plug disc 1902 moves downward inside the second tank body 1901, the external air can be sucked into the second tank body 1901 through the air intake pipe 1903. Conversely, when the second plug disc 1902 moves downward inside the second tank body 1901, the sucked air can be squeezed into the second connecting pipe 1905. Then it enters the interior of the blowing rack 1909 through the rectangular tube 1907 and the air pipe 1908, and is blown outward through the air outlet groove 1912, so that the light hollow rice and broken rice husks in the rice scattered by the guide rack four 1306 are blown out to the outside of the screening box 2. On the one hand, it can achieve the removal of hollow rice, and on the other hand, it can effectively prevent the fine rice husks from mixing into the subsequent screening operation. Moreover, through the scattering of the guide rack four 1306, the removal effect can be greatly improved, thereby improving the subsequent screening effect.

[0050] Among them, when the plug-in shaft 1302 rotates, it can also synchronously drive the pulley 2 1308 to rotate, and under the action of the transmission belt 2 1309, drive the rotating shaft 1910 to rotate, and then drive the fan blades 1911 to rotate inside the blowing rack 1909, thereby further increasing the air output, and further improving the removal effect of hollow rice and fine debris, and the rice controlled by the material dispensing roller 1305 enters the interior of the guide rack 4 1306 in batches, which can further improve the removal effect.

[0051] The flat material assembly 17 includes a plug-in board 1701, on one side of which a third extension rod 1618 is fixedly mounted, and the third extension rod 1618 is fixedly connected to the transverse plate 1617. A fixed box 1702 is fixedly mounted on the inner wall of the silo 15. One end of the plug-in board 1701 extends to the inside of the silo 15 and is located inside the fixed box 1702. Triangular blocks 1703 are fixedly mounted on both sides of the plug-in board 1701 located inside the fixed box 1702. The box 1702 is movably connected to two snap-in plates 1704 inside, a spring 1705 is fixedly connected between one side of the snap-in plate 1704 and an inner wall of one side of the fixed box 1702, a contact rod 1707 is fixedly installed on the surface of one side of the snap-in plate 1704, one end of the contact rod 1707 is fitted with the inclined surface of the triangular block 1703, a special-shaped frame 1706 is fixedly installed on the top surface of the snap-in plate 1704, and a rice pushing plate 1708 is fixedly installed on one end of the special-shaped frame 1706.

[0052] During operation, when the L-shaped plate 1613 moves up and down, it can drive the plug-in plate 1701 to move up and down inside the fixed box 1702 under the action of the second extension rod 1616 and the horizontal plate 1617. As the fixed box 1702 moves up and down, one end of the contact rod 1707 can contact different slopes on the inclined surface of the triangular block 1703, so that the clamping plate 1704 can move back and forth inside the fixed box 1702, thereby driving the special-shaped frame 1706 and the rice pushing plate 1708 to move back and forth inside the silo 15, thereby leveling the rice accumulated inside the silo 15, and by evenly moving the rice inside the silo 15 to the entrance of the material diverting box 1301, the feeding effect of the rice is improved. Through the above, the purpose of leveling the rice inside the silo 15 and improving the feeding effect of the material diverting box 1301 is achieved.

[0053] Specifically, the working process or working principle of the residue auxiliary screening device for rice production and processing is as follows: when in use, the rice to be screened is added into the interior of the silo 15, and then the motor 9 is started by controlling the motor 9. During the process of starting the motor 9, the transmission component 16 can be driven to operate. During the process of the transmission component 16 operating, the screening box 2 can be driven to move back and forth inside the main frame 1, and during the movement of the motor 9, the rice inside the silo 15 can be moved to the interior of the screening box 2 for screening. The intact rice will enter the interior of the sieve plate 2 4, and finally be introduced into the interior of the rice collecting box 7 through the guide frame 2 6 for collection. Large impurities and rice husks will be discharged to the outside through the guide frame 1 5, and the broken rice will be discharged to the outside through the guide frame 3 20, thereby achieving effective screening of the rice.

[0054] When the motor 9 is started, the transmission shaft 11 can be driven to rotate. When the transmission shaft 11 rotates, the rectangular plate 1601 is rotated. During the rotation of the rectangular plate 1601, the turntable 1602 can be driven to rotate. When the turntable 1602 rotates, the swing plate 1606 can be swung under the action of the connecting plate 1 1604. When swinging, the clamping block 1609 can be driven to move back and forth inside the fixed frame 1608 under the action of the connecting plate 2 1611. Finally, the screening box 2 is driven to move back and forth inside the main frame 1 through the connecting shaft 1612, thereby achieving effective screening of the rice entering the screening box 2.

[0055] When the turntable 1602 rotates driven by the rectangular plate 1601, it can drive the external frame 1603 to move up and down under the action of the rectangular plate 1601, drive the connecting plate 3 1807 to move up and down, and drive the plug disc 1809 to move up and down inside the tank body 1801. When the plug disc 1809 moves upward inside the tank body 1801, the antistatic agent inside the liquid storage tank 1802 can enter the tank body 1801 through the connecting pipe 1803. Conversely, when the plug disc 1809 moves downward inside the tank body 1801, the antistatic agent sucked into the tank body 1801 will be squeezed into the infusion tube 1805, and finally sprayed toward the rice selected by the material selection assembly 13, which can effectively prevent the problem of static electricity generated between the rice, the rice husk and impurities.

[0056] When the external frame 1603 moves up and down under the rotation of the turntable 1602, it can synchronously drive the L-shaped plate 1613 to move up and down inside the positioning plate 21, and then drive the roller 1615 and the installation shaft 1614 to move synchronously. Since the roller 1615 is in contact with the bottom surface of the guide frame 1306, the position of the guide frame 1306 is changed during the up and down movement of the guide frame 1306, that is, the rice entering the guide frame 1306 can be thrown upwards and then scattered into the screening box 2 under its own gravity. In this process, the antistatic agent can be better mixed with the rice. The contact allows the antistatic agent to better adhere to the outer surface of the rice, rice husks and debris, thereby improving the antistatic effect. When the motor 9 is started, the pulley 1303 is driven to rotate, thereby driving the connecting shaft 1302 to rotate inside the material box 1301 under the action of the transmission belt 1304, and finally driving the material roller 1305 to rotate inside the material box 1301. On the one hand, it can prevent the rice from being blocked during the feeding process, and on the other hand, it can enable the rice to enter the interior of the guide rack four 1306 in batches, so that there will not be too much rice in the interior of the guide rack four 1306 at one time, thereby increasing the scattering effect.

[0057] During the up and down movement of the L-shaped plate 1613, the circular rod 1913 can also be driven to move synchronously, driving the plug plate 1902 to move up and down inside the tank body 1901. When the plug plate 1902 moves downward inside the tank body 1901, the outside air can be sucked into the tank body 1901 through the air inlet pipe 1903. Conversely, when the plug plate 1902 moves downward inside the tank body 1901, the sucked air can be squeezed into the connecting pipe 1905, and then enter the blowing rack 1909 through the rectangular tube 1907 and the air supply pipe 1908, and blown out through the air outlet groove 1912, blowing the lightweight hollow rice and broken rice husks in the rice scattered by the guide rack 1306 to the outside of the screening box 2. On the one hand, the hollow rice can be removed, and on the other hand, the fine rice husks can be effectively prevented from mixing into the subsequent screening operation.
