Description

Technical Field

[0001] The present invention relates to the technical field of bean screening, and more specifically, to a bean screening device for bean product processing. Background Art

[0002] Soy products are foods made from beans such as soybeans, adzuki beans, peas, and broad beans. There are many varieties of these foods, which are rich in nutrients and are one of the important sources of protein in the diet. Before processing soybeans into soy products, the soybeans need to be screened to filter out impurities in the soybeans. Screening devices are usually used to remove impurities and defective products in the soybeans to ensure the purity of the soybeans during processing.

[0003] In the prior art, when soybeans are screened, the stored soybeans are usually taken out directly for storage. When the soybeans are stored, the fatty acids in the soybeans are easily affected by factors such as oxygen, light, and temperature during the storage process and undergo oxidation reactions. These oxidation reactions will generate intermediates such as hydroperoxides. These intermediates will further decompose to produce volatile compounds such as aldehydes, ketones, and alcohols. These compounds have different odor characteristics, among which aldehydes usually have a strong irritating odor, which may affect the storage quality and taste of the soybeans. After screening, untreated soybeans may still have residual gases such as aldehydes on their surface, which will affect the taste of soy products. Summary of the invention

[0034] In order to solve the problem that soybeans are prone to produce gases such as aldehydes after storage, when the stored soybeans need to be screened, the soybeans can be placed on the top of the feed box 5, and then the soybeans can be divided into specified amounts and dropped into the feed box 5 through the control component. By setting a hot air component, hot air can be provided to the feed box 5 when the control component is running, and the hot air can flow out through the air outlet holes set on the drum 42. By setting an anti-blocking component, the air outlet holes can be prevented from being blocked. At this time, the second sealing plate 19 is in a closed state, so that a certain amount of soybeans can be stored in the feed box 5 for heating treatment. By heating the soybeans, the enzymes in the soybeans can be thermally denatured and lose their activity, and at the same time, some aldehydes and other volatile compounds and harmful gases can be volatilized or thermally decomposed and reduced. By setting The uniform component can drive the roller 42 to move back and forth when the roller 42 blows out hot air, thereby promoting uniform heating of the soybeans. After the soybeans are heated for a short time, the control component can be used to drive the transmission component to move, thereby driving the second rotating rod 18 and the second sealing plate 19 to flip downward. When the second sealing plate 19 flips downward, the soybeans will fall downward onto the blocking plate 4. After the soybeans have fallen, the control component and the transmission component can be used to drive the second sealing plate 19 to be re-sealed, which is conducive to heating the next batch of soybeans. When the soybeans fall on the blocking plate 4, the larger impurities in the soybeans can be screened out by the blocking plate 4, and then the soybeans fall onto the sieve plate 3. The sieve plate 3 can screen out smaller impurities and shriveled soybeans, and finally the soybeans that meet the requirements are screened out.

[0035] Reference Figure 2-5The control component includes a motor 7, which is fixedly connected to one side of the feed box 5. A transmission rod 8 is fixedly connected to the output end of the motor 7. The transmission rod 8 passes through the feed box 5. A circular plate 9 is fixedly connected to one end of the transmission rod 8. A round rod 10 is fixedly connected to one side of the circular plate 9. A fixed sleeve 11 is fixedly connected to the other side of the feed box 5. A long rod 12 is slidably connected to the inner wall of the fixed sleeve 11. A first rack 16 is fixedly connected to the top of the long rod 12. A first rotating rod 14 is rotatably connected to the inner wall of the feed box 5. A first sealing plate 15 is fixedly connected to one side of the first rotating rod 14. A first gear 13 is fixedly connected to one end of the first rotating rod 14. The first gear 13 is arranged on one side of the long rod 12. A tooth seat 21 is fixedly connected to the bottom of the long rod 12. A half tooth 20 is fixedly connected to one end of the second rotating rod 18. The half tooth 20 is arranged on one side of the tooth seat 21. A first spring 22 is fixed to the bottom of the tooth seat 21, and a bottom plate 23 is fixed to the bottom of the first spring 22. The bottom plate 23 is fixed to the bottom of the feed box 5. The first rack 16, the long rod 12, the first rotating rod 14, the first closing plate 15, the second closing plate 19, the second rotating rod 18, the half tooth 20 and the tooth seat 21 are each provided with two groups, and are symmetrically distributed on both sides of the feed box 5. A cross plate 17 is fixed between the two groups of the first racks 16, and an L-shaped plate 26 is fixed to the bottom of the cross plate 17. An inclined plate 24 is fixed to the inner wall of the feed box 5, and a second spring 25 is fixed to the top of the inclined plate 24. The second spring 25 is fixed to the bottom of the first closing plate 15. Four groups of the inclined plates 24 and the second springs 25 are each provided, and are symmetrically distributed at the bottom of the first closing plate 15 and the second closing plate 19. A placing bucket 6 is fixed to the top of the feed box 5.

[0036] When it is necessary to release the heated soybeans from the feed box 5, the motor 7 can be started, and the transmission rod 8 and the circular plate 9 can be driven to rotate by the motor 7, and the circular plate 9 will drive the round rod 10 to rotate together when rotating. When the round rod 10 rotates to one side, it will push the L-shaped plate 26 to move downward, and when the L-shaped plate 26 moves downward, it will drive the cross plate 17 and the two groups of first racks 16, the long rod 12 and the fixed seat to move downward together. By setting the fixing sleeve 11, the movement trajectory of the long rod 12 can be limited. When the fixed seat moves downward, the half tooth 20 will be driven to rotate by the transmission assembly, and when the half tooth 20 rotates, it will drive the second rotating rod 18 and the second sealing plate 19 to rotate together, so that the soybeans in the feed box 5 can fall out downward, and when the fixed seat moves to the bottom of the half tooth 20, the two groups of second rotating rods 18, the second sealing plate 19 and the half tooth 20 can be pushed to reset together by the two groups of inclined plates 24 and the second spring 25, and the feed box 5 Two groups of limiting blocks are arranged inside to limit the position where the second sealing plate 19 flips upward, thereby closing the bottom of the feed box 5. As the round rod 10 continues to rotate downward, it will push the long rod 12, the first rack 16 and the fixed seat to move downward together, and continue to squeeze the second spring 25. At this time, the first rack 16 moves to one side of the first gear 13, and gradually drives the first gear 13, the first rotating rod 14 and the first sealing plate 15 to flip over when moving downward, so that the soybeans at the top of the feed box 5 can be placed downward into the feed box 5. When the round rod 10 moves away from one side of the L-shaped plate 26, the first spring 22 will push the tooth seat 21, the long rod 12 and the first rack 16 to reset upward, and at the same time drive the first gear 13, the first rotating rod 14 and the first sealing plate 15 to reverse and reset together, so that the top of the feed box 5 can be closed, thereby blocking the soybeans in the placement bucket 6 from entering the feed box 5, and a certain amount of soybeans can be added to the feed box 5.

[0037] Reference Figure 6 The transmission assembly includes an inclined block 28, which is arranged on one side of the half tooth 20. A mounting groove is opened on one side of the tooth seat 21. A third spring 27 is fixed to the inner wall of the mounting groove. The third spring 27 is fixed to one side of the inclined block 28. The top of the inclined block 28 is inclined.

[0038] When the tooth seat 21 moves downward with the long rod 12, the half tooth 20 can be driven to rotate through the bottom of the inclined block 28, thereby driving the half tooth 20, the second rotating rod 18 and the second sealing plate 19 to rotate together. When the tooth seat 21 moves upward, the half tooth 20, the second round rod 10 and the second sealing plate 19 have been pushed back to their original position by the second spring 25. When the top end of the inclined block 28 contacts one side of the half tooth 20, since one side of the inclined block 28 is inclined, when it contacts the convex tooth of the half tooth 20, the thrust of the convex tooth can push the inclined block 28 into the installation groove and squeeze the spring, so that the tooth seat 21 will not interfere with the half tooth 20 when it moves upward.

[0039] Reference Figure 8 and Fig.12 The hot air assembly includes a first bevel gear 29, which is fixed to the outer wall of the transmission rod 8. A second bevel gear 30 is meshed with one side of the first bevel gear 29, a third rotating rod 31 is fixed to one side of the second bevel gear 30, a second gear 32 is fixed to one end of the third rotating rod 31, a transmission belt 33 is meshed with the outer wall of the second gear 32, a third gear 34 is meshed on the inner wall of the transmission belt 33 away from the second gear 32, the size of the third gear 34 is smaller than the second gear 32, a short rod 35 is fixed to one side of the third gear 34, and a fan blade is fixed to the outer wall of the short rod 35 36, a cover opening 37 is fixedly connected to one side of the feed box 5, the short rod 35 and the fan blades 36 are arranged on the inner wall of the cover opening 37, the side of the cover opening 37 away from the feed box 5 is inclined, a heating wire 38 is fixedly connected to the inside of the cover opening 37, a positioning rod 39 is fixedly connected to the inner wall of the cover opening 37, the short rod 35 is rotatably connected to the inner wall of the positioning rod 39, a connecting sleeve 40 is fixedly connected to one side of the inner wall of the feed box 5, the connecting sleeve 40 is arranged on one side of the cover opening 37, the connecting sleeve 41 is made of rubber, a ring 41 is fixedly connected to one side of the connecting sleeve 41, and the roller 42 is rotatably connected to the inner wall of the ring 41.

[0040] When the motor 7 drives the transmission rod 8 to rotate, it will drive the first bevel gear 29 set on the outer wall of the transmission rod 8 to rotate, and the first bevel gear 29 will drive the second bevel gear 30 and the third rotating rod 31 on one side to rotate together when rotating, and the second gear 32 set at one end of the third rotating rod 31 will also rotate accordingly. When the second gear 32 rotates, it will drive the transmission belt 33 set on the outer wall to rotate, and when the transmission belt 33 rotates, it will drive the third gear 34 on the other side of the inner wall to rotate. Since the size of the third gear 34 is smaller than the second gear 32, the third gear 34 can rotate. The rotation speed of the third gear 34 will also be greater than that of the second gear 32. When the third gear 34 rotates, it will drive the short rod 35 and the fan blade 36 on one side to rotate. When the fan blade 36 rotates, it will provide wind force to the cover opening 37. The heating wire 38 arranged in the cover opening 37 will increase the temperature of the wind flow, turning the wind flow into hot air. The hot air enters the drum 42 through the rubber connecting sleeve 40. Since the outer wall of the drum 42 is provided with multiple groups of air outlet holes, the hot air will flow out to the outside through the multiple groups of air outlet holes, and the hot air can be used to heat the soybeans in the feed box 5.

[0041] Reference Fig.10The anti-blocking component includes a center rod 43, which is fixedly connected to the center of the inner wall of the drum 42. A cylinder 44 is fixedly connected to the outer wall of the center rod 43. A mounting groove is provided at the top of the cylinder 44. A fourth spring 45 is fixedly connected to the inner wall of the mounting groove. The top of the fourth spring 45 passes through the air outlet. An enlarged opening is provided at the top of the air outlet. A blocking block 46 is fixedly connected to the top of the fourth spring 45. The blocking block 46 is provided at the top of the air outlet. The shape of the blocking block 46 fits the shape of the air outlet. A guide plate 57 is fixedly connected to the outer wall of the center rod 43. The shape of the guide plate 57 is spiral.

[0042] When the hot air enters the interior of the drum 42, it will flow along the outer wall of the center rod 43. When the hot air flows out from the air outlet, the thrust generated by the hot air will push the block 46 away. At the same time, when the block 46 moves, it will stretch the fourth spring 45. Since the top of the air outlet is provided with an expansion port, when the hot air passes through the expansion port, it will cooperate with the block 46 to diffuse the hot air to the surroundings, which can increase the heating range of the soybeans. The spiral guide plate 57 provided on the outer wall of the center rod 43 can facilitate the continuous entry of the wind into the interior of the drum 42. When the wind stops entering the drum 42, the fourth spring 45 can be reset to pull the block 46 to reset, so that the block 46 can close the air outlet to prevent smaller soybeans or impurities from entering the interior of the drum 42 through the air outlet.

[0043] Reference Fig. 9 The uniform component includes a reciprocating screw 47, which is fixed to the outer wall of the transmission rod 8. The outer wall of the reciprocating screw 47 is slidably connected with a nut 48, and the inner wall of the nut 48 is fixed with a circular protrusion. Guide blocks 49 are fixed on both sides of the inner wall of the feed box 5, and a cover plate 50 is fixed between the two groups of guide blocks 49. The cover plate 50 is arranged at the top of the reciprocating screw 47, and limiting plates 56 are fixed on both sides of the nut 48. The limiting plates 56 are arranged at the bottom of the cover plate 50. The bottom of the nut 48 is fixed with a sleeve block 51. The center of the roller 42 is rotatably connected to the inner wall of the sleeve block 51. The outer wall of the roller 42 is fixed with two groups of convex rings, and the two groups of convex rings are arranged on both sides of the sleeve block 51.

[0044] When the transmission rod 8 rotates, the reciprocating screw 47 is also driven to rotate. When the reciprocating screw 47 rotates, the nut 48 arranged on its outer wall is driven to slide back and forth. When the nut 48 slides back and forth, it drives the limiting plates 56 on both sides to slide at the bottom of the cover plate 50. By setting two groups of limiting plates 56, the movement trajectory of the nut 48 can be limited. The sleeve block 51 set at the bottom of the nut 48 will also slide with the nut 48. When the sleeve block 51 moves, it will drive the internal sleeve roller 42 to move back and forth, thereby changing the position of heating the soybeans. The rubber connecting sleeve 40 can keep hot air continuously added to the roller 42. By setting the guide block 49, the soybeans can be prompted to fall to the center of the roller 42. By setting the cover plate 50, the soybeans can be prevented from interfering with the operation of the reciprocating screw 47 and the nut 48.

[0045] Reference Fig.14 A fourth gear 52 is fixedly connected to one end of the roller 42 away from the sleeve ring 41 , a second rack 53 is fixedly connected to one side of the inner wall of the feed box 5 , and the fourth gear 52 is rotatably connected to one side of the second rack 53 .

[0046] When the drum 42 moves, it will drive the fourth gear 52 set on one side to move together. When the fourth gear 52 moves, it will rotate through the meshing rack at the bottom. When the fourth gear 52 rotates, it will also drive the drum 42 to rotate. When the drum 42 rotates, it will adjust the directions of multiple groups of air outlets, thereby further promoting uniform heating of the soybeans.

[0047] Reference Fig.12 A filter plate 54 is fixedly connected to the inner wall of the cover opening 37, and the short rod 35 is rotatably connected to the inner wall of the filter plate 54. A scraper 55 is fixedly connected to one side of the short rod 35, and one side of the scraper 55 is tightly attached to one side of the filter plate 54. The bottom of the scraper 55 is inclined.

[0048] By arranging a filter plate 54 inside the hood opening 37, when the airflow enters the hood opening 37, impurities can be blocked outside the hood opening 37 by the filter plate 54, and when the short rod 35 rotates, it will drive the scraper 55 to rotate together. When the scraper 55 rotates, it will scrape off the impurities trapped outside the filter plate 54, and the inclination of the bottom of the scraper 55 can help to scrape off the impurities on the inclined part of the hood opening 37.

[0049] Working principle: In order to solve the problem that soybeans are prone to produce aldehydes and other gases after storage, when the stored soybeans need to be screened, the motor 7 is started, and the motor 7 drives the transmission rod 8 and the circular plate 9 to rotate, and the circular plate 9 drives the round rod 10 to rotate together when rotating. When the round rod 10 rotates to one side, it pushes the L-shaped plate 26 to move downward, and when the L-shaped plate 26 moves downward, it drives the cross plate 17 and the two sets of first racks 16, the long rod 12 and the fixed seat to move downward together. By setting the fixing sleeve 11, the moving trajectory of the long rod 12 can be limited. When moving downward, the half tooth 20 can be driven to rotate through the bottom of the inclined block 28, thereby driving the half tooth 20, the second rotating rod 18 and the second sealing plate 19 to rotate together, and the soybeans in the feed box 5 can fall out downward. When the fixed seat moves to the bottom of the half tooth 20, the two groups of second rotating rods 18, the second sealing plate 19 and the half tooth 20 can be pushed to reset together through the two groups of inclined plates 24 and the second spring 25. Two groups of limiting blocks are provided inside the feed box 5 to limit the position of the second sealing plate 19 flipping upward, thereby closing the bottom of the feed box 5. As the round rod 10 continues to rotate downward, The first spring 22 pushes the tooth seat 21, the long rod 12 and the first rack 16 to reset upwards, and at the same time drives the first gear 13, the first rotating rod 14 and the first sealing plate 15 to reverse and reset together. , the top of the feed box 5 can be closed, thereby blocking the soybeans in the bucket 6 from entering the feed box 5, and a fixed amount of soybeans can be added to the feed box 5. When the tooth seat 21 moves upward, the half tooth 20, the second round rod 10 and the second sealing plate 19 have been pushed back by the second spring 25. When the top of the inclined block 28 contacts one side of the half tooth 20, since one side of the inclined block 28 is inclined, when it contacts the convex tooth of the half tooth 20, the thrust of the convex tooth can push the inclined block 28 into the installation groove and squeeze the spring, so that the tooth seat 21 will not interfere with the half tooth 20 when it moves upward;When the motor 7 drives the transmission rod 8 to rotate, it will also drive the first bevel gear 29 to rotate. When the first bevel gear 29 rotates, it will drive the second bevel gear 30, the third rotating rod 31, and the second gear 32 to rotate. The second gear 32 will drive the transmission belt 33 to rotate. When the transmission belt 33 rotates, it will drive the third gear 34 on the other side of the inner wall to rotate. Since the size of the third gear 34 is smaller than the second gear 32, the rotation speed of the third gear 34 will also be greater than the second gear 32. When the third gear 34 rotates, it will drive the short rod 35 and the fan blade 36 on one side to rotate. When the fan blade 36 rotates, it will provide wind force into the hood 37. The filter plate 54 can block impurities outside the hood 37. When the short rod 35 rotates, it will simultaneously drive the scraper 55 to rotate together. When the scraper 55 rotates, it will scrape off the impurities trapped outside the filter plate 54. By arranging a heating wire 38 in the hood 37, the temperature of the wind flow can be increased, so that the wind flow becomes hot wind. The hot wind enters through the rubber connecting sleeve 40 The hot air enters the drum 42. Since the outer wall of the drum 42 is provided with multiple groups of air outlet holes, the hot air will flow outward through the multiple groups of air outlet holes. When the hot air flows out from the air outlet holes, the thrust generated by the hot air will push the block 46 away. At the same time, when the block 46 moves, it will stretch the fourth spring 45. Since the top of the air outlet hole is provided with an expansion hole, when the hot air passes through the expansion hole, it will cooperate with the block 46 to diffuse the hot air to the surroundings, which can increase the range of heating the soybeans. By heating the soybeans, the enzymes in the soybeans can be thermally denatured and lose their activity, and at the same time, some aldehydes and other volatile compounds and harmful gases can be volatilized or thermally decomposed and reduced. The spiral guide plate 57 provided on the outer wall of the center rod 43 can facilitate the continuous entry of the wind flow into the interior of the drum 42. When the wind flow stops entering the drum 42, the fourth spring 45 can be reset to pull the block 46 to reset, so that the block 46 closes the air outlet hole to prevent smaller soybeans or impurities from entering the interior of the drum 42 through the air outlet hole.When the transmission rod 8 rotates, the reciprocating screw 47 is also driven to rotate. When the reciprocating screw 47 rotates, the nut 48, the limiting piece 56 and the sleeve block 51 are driven to slide back and forth. By setting two sets of limiting pieces 56 to slide at the bottom of the cover plate 50, the movement trajectory of the nut 48 can be limited. When the sleeve block 51 moves, it drives the roller 42 set inside to move back and forth, thereby changing the position of heating the soybeans, and the rubber connecting sleeve 40 can keep hot air added to the roller 42. When the roller 42 moves, it drives the fourth gear 52 set on one side to move together, and when the fourth gear 52 moves, it will engage the bottom gear The gear rack 52 rotates, and the fourth gear 52 also drives the drum 42 to rotate when rotating. When the drum 42 rotates, the directions of the multiple groups of air outlet holes are adjusted, so as to further promote the uniform heating of the soybeans. By setting the guide block 49, the soybeans can be prompted to fall to the drum 42 at the center. By setting the cover plate 50, the soybeans can be prevented from interfering with the operation of the reciprocating screw 47 and the nut 48. When the soybeans fall on the blocking plate 4, the blocking plate 4 can be used to screen out the larger impurities in the soybeans. Then the soybeans fall on the sieve plate 3, and the sieve plate 3 can screen out the smaller impurities and shriveled soybeans, so that the soybeans that meet the requirements are finally screened out. ;
