Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of rice industry feeding, and particularly to a feeding device for deep processing of rice industry. Background Art
[0002] Belt elevators are commonly used vertical or inclined conveying equipment in the deep processing production line of the rice industry. They are mainly used to continuously lift materials such as paddy, brown rice, and polished rice from low places to high places, realizing automatic feeding. The paddy in the raw material bin is cleaned, and then lifted to the drying equipment and finally conveyed to other cleaning equipment such as vibrating screens and stone separators, or conveyed to processes such as hulling and milling. The processed finished rice is lifted to the packaging line or the finished product warehouse, adapting to the layout of multi-story factories. Belt elevators are the key equipment to achieve efficient, continuous, and automated production in the deep processing of rice industry, shortening the material transfer time and ensuring the smooth flow of the production line.
[0003] In the existing method, paddy raw materials are taken out from the raw material bin, cleaned through a cleaning pool, and then transported by a belt elevator. However, it is impossible to automatically separate impurities such as stones, chaff, broken shells, and broken straws during the cleaning process. Hard impurities such as stones and broken shells are mixed into subsequent processes, resulting in abnormal wear of the sand roller / iron roller of the rice mill and shortening the service life of the equipment. At the same time, the remaining broken straws and chaff will reduce the purity of the finished rice, causing customer complaints. The accumulation of impurities blocks the discharge port or pipeline of the elevator, causing shutdown for cleaning and affecting continuous production. The traditional horizontal-flow cleaning pool only relies on soaking, and cannot make light impurities such as broken straws float or heavy impurities such as stones settle and separate through turbulence. It lacks an automatic slag discharge structure and requires manual fishing, resulting in the risk of impurity backflow. Summary of the Invention

[0016] Beneficial effects
[0017] The present invention has the following beneficial effects:
[0018] (1). In the feeding device for deep processing of the rice industry, the wave-making push plate stably performs reciprocating linear movement in the wave-making pool. During the process of the wave-making push plate moving forward towards the mesh plate, it pushes the water, thereby generating water waves. The water waves push the light impurities such as straws, empty husks, and chaff that have not been completely cleaned. The water waves push these impurities, and the high-speed air flow at the second air outlet blows these impurities towards the waste outlet direction. Since the discharge inclined surface is inclined, the water flow drives these impurities to quickly flow into the waste trough. The waves generate a thrust on the floating impurities such as straws, empty husks, and chaff, causing them to gather towards the waste outlet direction. The high-speed air flow at the second air outlet forms a synergistic effect with the water waves, further blowing the light impurities and accelerating their flow towards the waste trough. The discharge inclined surface of the cleaning tank utilizes the gravity of the water flow to enable the impurities to quickly flow into the waste trough along with the waves, avoiding residue. The dual action of the water waves and the air flow realizes precise separation from the plump rice grains. The plump rice grains are sent to the drying equipment for further deep processing, thereby ensuring the product quality.
[0019] (2). In the feeding device for deep processing of the rice industry, the sieve plate performs stable reciprocating swinging motion, so that the rice grains move from the magnetic plate of the sieve plate to the material leakage port. When the rice grains enter the sieve plate, the magnetic plate adsorbs metal impurities such as iron filings. The reciprocating swing of the sieve plate evenly distributes the rice grains. The light impurities such as straws and empty husks float on the upper layer, and the plump rice grains sink to the lower layer. Moreover, the sieve plate is inclined, promoting the rice grains to move along the magnetic plate towards the material leakage port, realizing continuous sorting. The magnetic adsorption effectively removes metal impurities, improves the purity of the rice grains and the quality of the subsequent processed products. The reciprocating swing accelerates the separation of impurities, separating the light / heavy impurities. The plump rice grains enter the cleaning tank from the material leakage port.
[0020] (3). In the feeding device for deep processing of the rice industry, the air flows rapidly from the first air outlet and the second air outlet. The first air outlet corresponds to the ventilation holes of the sieve plate. During the reciprocating swing of the sieve plate, it will lift the ash. The air flow speed at the first air outlet is fast, so as to blow the dust out of the sieve plate from the inside to the outside, and can blow out some light impurities such as straws and empty husks. The high-speed air flow can penetrate into the ventilation holes of the sieve plate and thoroughly blow out the tiny dust and light impurities that are difficult to remove by mechanical vibration. The synergistic effect of the air flow and the swing of the sieve plate makes the dust removal effect more remarkable, greatly improving the purity of the rice grains. In addition to dust, it can also effectively blow out the light impurities in the rice grains, such as straws and empty husks.
[0021] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the advantages described above. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0032] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred components or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0033] Please refer to Figures 1 - 8 , an embodiment of the present invention provides a technical solution: a feeding device for deep processing of the rice industry, including a cleaning tank 1 and a belt elevator 2 installed on the inner surface of the cleaning tank 1. A rotating motor 3 is installed on the outer surface of the cleaning tank 1. A rotating shaft 4 is installed on the outer surface of the output end of the rotating motor 3. A transmission component is installed on the outer surface of the rotating shaft 4. A vibration screening and feeding component is installed on one end surface of the rotating shaft 4. A reciprocating wave-making component is movably installed inside the cleaning tank 1. A dust blowing component is installed inside the cleaning tank 1;
[0034] The reciprocating wave-making assembly includes a reciprocating lead screw 23 and a lead screw slider 25. The reciprocating lead screw 23 is movably installed inside the cleaning tank 1. A lead screw slider 25 is movably installed on the outer surface of the lead screw slider 25. A wave-making push plate 27 is installed on the outer surface of the lead screw slider 25. A limiting sliding cavity 26 is formed inside the cleaning tank 1. The inner wall of the limiting sliding cavity 26 is in movable contact with the outer surface of the wave-making push plate 27. A wave-making pool 28 is installed on the inner surface of the cleaning tank 1. The inner surface of the wave-making pool 28 is in movable contact with the outer surface of the wave-making push plate 27. A mesh plate 24 is installed on the inner surface of the cleaning tank 1. The transmission assembly is used to drive the reciprocating wave-making assembly to work, so as to facilitate the cleaning of sundries such as chaff, broken husks and broken straw on the water surface. The wave-making push plate 27 stably performs a reciprocating linear movement in the wave-making pool 28. When the wave-making push plate 27 advances towards the mesh plate 24, it pushes the water, thereby generating water waves. The water waves push light impurities such as uncompletely cleaned straw, empty husks, and chaff. Chaff is the rice with low internal starch content, loose structure and density less than water, so it floats. The water waves push these impurities, and the high-speed air flow from the second air outlet 13 blows these impurities towards the waste outlet 104. Due to the inclination of the discharge inclined surface 102, the water flow drives these impurities to quickly flow into the waste chute 103. Through the cooperation of the reciprocating lead screw 23 and the lead screw slider 25, when the wave-making push plate 27 advances forward, it pushes the water surface to form waves. The waves generate a thrust on floating impurities such as straw, empty husks, and chaff, causing them to gather towards the waste outlet 104. The high-speed air flow from the second air outlet 13 and the water waves form a synergistic effect, further blowing the light impurities and accelerating their flow towards the waste chute 103. The discharge inclined surface 102 of the cleaning tank 1 utilizes the gravity of the water flow to make the impurities quickly flow into the waste chute 103 along with the waves, avoiding residue. The dual action of water waves and air flow can remove the sediment adhering to the surface of the rice grains or the light impurities hidden between the grains, making the impurity removal more thorough. Chaff floats naturally due to its low density. With the push of the waves, it realizes the precise separation from the plump rice. The linear reciprocating motion of the wave-making push plate 27 simulates the artificial wave-pushing action, and the water flow is disturbed evenly, avoiding the deposition of impurities. The plump rice is sent to the drying equipment for further deep processing, thus ensuring the product quality.
[0035] The transmission assembly includes a driving transmission wheel 14 and a first transmission shaft 17. The driving transmission wheel 14 is installed on the outer surface of the rotating shaft 4. The first transmission shaft 17 is movably installed inside the cleaning tank 1. A driven transmission wheel 15 is installed on the outer surface of the first transmission shaft 17. A belt 16 is jointly movably installed on the outer surfaces of the driving transmission wheel 14 and the driven transmission wheel 15. The rotating shaft 4 synchronously drives the main transmission wheel to perform a rotational motion. The main transmission wheel drives the driven transmission wheel 15 to perform a rotational motion through the belt 16. The driven transmission wheel 15 drives the first transmission shaft 17 to perform a rotational motion.
[0036] A first transmission shaft 17 has a first bevel gear 18 mounted on its outer surface. A second transmission shaft 20 is installed inside the cleaning tank 1. A second bevel gear 19 is mounted on one end surface of the second transmission shaft 20. The outer surface of the second bevel gear 19 meshes with the outer surface of the first bevel gear 18. The first transmission shaft 17 drives the first bevel gear 18 to rotate. The outer surface of the first bevel gear 18 meshes with the outer surface of the second bevel gear 19, so that the second bevel gear 19 and the second transmission shaft 20 rotate. The second transmission shaft 20 drives a third bevel gear 21 to rotate.
[0037] A third bevel gear 21 is mounted on the outer surface of the second transmission shaft 20. A fourth bevel gear 22 is mounted on one end surface of the reciprocating lead screw 23. The outer surface of the fourth bevel gear 22 meshes with the outer surface of the third bevel gear 21. The outer surface of the third bevel gear 21 meshes with the outer surface of the fourth bevel gear 22. The fourth bevel gear 22 drives the reciprocating lead screw 23 to rotate. The reciprocating lead screw 23 cooperates with the lead screw slider 25, and the limit sliding cavity 26 limits the movement of the wave-making push plate 27.
[0038] The interior of the cleaning tank 1 is provided with three material leakage inclined surfaces 101, a waste outlet 104 is opened inside the cleaning tank 1, a discharge inclined surface 102 is provided inside the cleaning tank 1, and a waste slot 103 is opened inside the cleaning tank 1. All the paddy in the cleaning tank 1 flows onto the belt elevator 2 through the three material leakage inclined surfaces 101 on the three sides of the cleaning tank 1. When the paddy is discharged through the material leakage port 802, the paddy naturally converges and flows to the belt elevator 2 to achieve continuous discharging. The discharge inclined surface 102 of the cleaning tank 1 utilizes the gravity of the water flow to quickly converge the impurities into the waste slot 103 with the waves, avoiding residues.
[0039] The vibration screening and feeding assembly includes an eccentric crank 5 and a crank rod 6. The eccentric crank 5 is mounted on one end surface of the rotating shaft 4. A crank rod 6 is movably mounted on the outer surface of the eccentric crank 5. A connecting column 7 is movably mounted inside the outer surface of the crank rod 6. A sieve plate 8 is mounted on the outer surface of the connecting column 7. The rotating motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the eccentric crank 5 to rotate. The eccentric crank 5 drives the crank rod 6 to perform a reciprocating swinging motion. The crank rod 6 drives the connecting column 7 and the sieve plate 8 to perform a reciprocating swinging motion.
[0040] Four movable columns 9 are installed on the outer surfaces of both the sieve plate 8 and the cleaning tank 1. The eight movable columns 9 are movably installed in pairs with connecting rods 10. A magnetic plate 801 is provided inside the sieve plate 8. Leakage openings 802 are evenly distributed inside the sieve plate 8. Ventilation holes 803 are evenly distributed inside the sieve plate 8. The curved rod 6 drives the connecting column 7 and the sieve plate 8 to perform a reciprocating swinging motion, and the sieve plate 8 is inclined. The sieve plate 8 drives the four movable columns 9 to correspondingly extrude the connecting rods 10, so that the four connecting rods 10 swing on the four movable columns 9 outside the cleaning tank 1, facilitating the stable reciprocating swinging motion of the sieve plate 8. Thus, the paddy rice moves from the magnetic plate 801 of the sieve plate 8 to the leakage openings 802. When the paddy rice enters the sieve plate 8, the magnetic plate 801 adsorbs metal impurities such as iron filings. The reciprocating swing of the sieve plate 8 evenly distributes the paddy rice. Light impurities such as straws and empty husks float on the upper layer, and plump paddy rice sinks to the lower layer. Moreover, the sieve plate 8 is inclined, prompting the paddy rice to move along the magnetic plate 801 towards the leakage openings 802, realizing continuous sorting. Magnetic adsorption effectively removes metal impurities, improving the purity of the paddy rice and the quality of subsequent processed products. The reciprocating swing accelerates the separation of impurities, separating light / heavy impurities. The plump paddy rice enters the cleaning tank 1 from the leakage openings 802.
[0041] The soot blowing assembly includes a blower 11, a first air outlet 12, and a second air outlet 13. The blower 11 is installed on the outer surface of the cleaning tank 1. The first air outlet 12 is opened inside the cleaning tank 1. The second air outlet 13 is opened inside the cleaning tank 1. The blower 11 accelerates the air flow speed. The air flows at an accelerated speed from the first air outlet 12 and the second air outlet 13. The first air outlet 12 corresponds to the ventilation holes 803 of the sieve plate 8. During the reciprocating swing of the sieve plate 8, dust will be lifted up. The air flow speed at the first air outlet 12 is fast, thus blowing the dust out of the sieve plate 8 from the inside to the outside, and can also blow out some light impurities such as straws and empty husks. The high-speed air flow can penetrate into the ventilation holes 803 of the sieve plate 8, thoroughly blowing out the tiny dust and light impurities that are difficult to remove by mechanical vibration. The synergistic effect of the air flow and the swing of the sieve plate 8 makes the dust removal effect more remarkable, greatly improving the purity of the paddy rice. In addition to dust, it can also effectively blow out light impurities in the paddy rice, such as straws and empty husks.
[0042] Workflow of the present invention: When deep processing of paddy is required to manufacture products, the paddy needs to be cleaned and screened. It is continuously conveyed to the sieve plate 8 through a conveyor belt. The rotation motor 3 is controlled by a controller to operate. The rotation motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the eccentric crank 5 to rotate. The eccentric crank 5 drives the curved rod 6 to reciprocate. The curved rod 6 drives the connecting column 7 and the sieve plate 8 to reciprocate. The sieve plate 8 is inclined. The sieve plate 8 drives the four movable columns 9 to correspondingly squeeze the connecting rods 10, so that the four connecting rods 10 swing on the four movable columns 9 outside the cleaning tank 1 correspondingly, facilitating the stable reciprocating movement of the sieve plate 8. Thus, the paddy moves from the magnetic plate 801 of the sieve plate 8 to the leakage opening 802. When the paddy enters the sieve plate 8, the magnetic plate 801 adsorbs metal impurities such as iron filings. The reciprocating movement of the sieve plate 8 makes the paddy evenly distributed. Light impurities such as straws and empty husks float on the upper layer, and plump paddy sinks to the lower layer. And the sieve plate 8 is inclined, prompting the paddy to move along the magnetic plate 801 towards the leakage opening 802, realizing continuous sorting. Magnetic adsorption effectively removes metal impurities, improves the purity of paddy and the quality of subsequent processed products. The reciprocating movement accelerates the separation of impurities, separating light / heavy impurities. The plump paddy enters the cleaning tank 1 from the leakage opening 802.
[0043] Moreover, the blower 11 is synchronously powered on to operate. The blower 11 accelerates the air flow rate. The air flows at an accelerated speed from the first air outlet 12 and the second air outlet 13. The first air outlet 12 corresponds to the ventilation holes 803 of the sieve plate 8. During the reciprocating movement of the sieve plate 8, dust will be lifted up. The air flow rate at the first air outlet 12 is fast, so as to blow the dust out of the sieve plate 8 outward. And it can also blow out some light impurities such as straws and empty husks. The high-speed air flow can penetrate into the ventilation holes 803 of the sieve plate 8, thoroughly blowing out the tiny dust and light impurities that are difficult to remove by mechanical vibration. The synergistic effect of the air flow and the swing of the sieve plate 8 makes the dust removal effect more remarkable, greatly improving the purity of the paddy. In addition to dust, it can also effectively blow out the light impurities in the paddy, such as straws and empty husks.
[0044] When the paddy rice discharges through the material leakage port 802, all the paddy rice on the material leakage inclined surfaces 101 on three sides of the cleaning tank 1 flows onto the belt elevator 2. When the paddy rice discharges through the material leakage port 802, the paddy rice naturally converges and flows to the belt elevator 2, realizing continuous discharging. A water outlet pipe and a water inlet pipe are installed inside the cleaning tank 1 to keep the water surface height of the cleaning tank 1 constant, which belongs to the prior art field and will not be elaborated here. The rotating shaft 4 synchronously drives the main transmission wheel to perform a rotating motion. The main transmission wheel drives the driven transmission wheel 15 to perform a rotating motion through the belt 16. The driven transmission wheel 15 drives the first transmission shaft 17 to perform a rotating motion. The first transmission shaft 17 drives the first bevel gear 18 to perform a rotating motion. The outer surface of the first bevel gear 18 meshes with the outer surface of the second bevel gear 19, so that the second bevel gear 19 and the second transmission shaft 20 perform a rotating motion. The second transmission shaft 20 drives the third bevel gear 21 to perform a rotating motion. The outer surface of the third bevel gear 21 meshes with the outer surface of the fourth bevel gear 22. The fourth bevel gear 22 drives the reciprocating lead screw 23 to perform a rotating motion. The reciprocating lead screw 23 cooperates with the lead screw slider 25, and the limit sliding cavity 26 limits the movement of the wave-making push plate 27, so that the lead screw slider 25 drives the wave-making push plate 27 to perform a reciprocating movement in the wave-making pool 28. The wave-making push plate 27 stably performs a reciprocating linear movement in the wave-making pool 28. When the wave-making push plate 27 advances towards the mesh plate 24, it pushes the water, thus generating water waves. The water waves push the light impurities such as straws, empty husks and unripened grains. Unripened grains have a low starch content inside the paddy rice that is not fully filled with grains, with a loose structure and a density less than that of water, so they float up. The water waves push these impurities, and the high-speed air flow at the second air outlet 13 blows these impurities towards the waste outlet 104. Due to the inclination of the material discharging inclined surface 102, the water flow drives these impurities to quickly flow into the waste trough 103. Through the cooperation of the reciprocating lead screw 23 and the lead screw slider 25, when the wave-making push plate 27 advances, it pushes the water surface to form waves. The waves generate a thrust on the floating impurities such as straws, empty husks and unripened grains, causing them to gather towards the waste outlet 104. The high-speed air flow at the second air outlet 13 and the water waves form a synergistic effect, further blowing the light impurities and accelerating their flow towards the waste trough 103. The material discharging inclined surface 102 of the cleaning tank 1 utilizes the gravity of the water flow to make the impurities quickly flow into the waste trough 103 along with the waves, avoiding residues. The dual action of the water waves and the air flow can remove the sediment adhering to the surface of the paddy rice or the light impurities hidden between the grains, making the impurity removal more thorough. The unripened grains float up naturally due to their low density, and with the promotion of the waves, the precise separation from the plump paddy rice is realized. The linear reciprocating motion of the wave-making push plate 27 simulates the artificial wave-pushing action, with uniform water flow disturbance and avoiding impurity deposition. The plump paddy rice is sent to the drying equipment for further deep processing, thus ensuring the product quality.
[0045] Finally, the fully saturated and plump paddy rice drops onto the belt elevator 2, and the paddy rice is cleaned during the dropping process. Finally, it is batch-transported upward by the belt elevator 2 and enters drying and deep processing.
