Description

Technical Field

[0002] Rice, also known as paddy rice, is a food made from paddy after processes such as cleaning, hulling, milling, and finished product finishing. Rice contains nearly 64% of the nutrients in paddy and more than 90% of the nutrients required by the human body. The carbohydrates in rice are mainly starch, and the protein contained is mainly oryzenin, followed by glutelin and globulin. The biological value of its protein and the composition ratio of amino acids are higher than those of cereal crops such as wheat, barley, millet, and corn, and it is the main food for people in most parts of China.

Its characteristics are that it also includes a feeding port, a first material chamber, a second material chamber, a hulling chamber, and a rice milling device. Compared with the prior art, the present invention processes the rice grains before hulling and shelling. Through the cooperation of the lifting member and the wave protrusions, the up and down bumping of the second material chamber is realized, so that the connection between the rice husk and the rice will not be too tight; the present invention adopts a relatively closed method to prevent dust from escaping into the space. Among them, the dust on the rice husk can be well separated through the bumping in the second material chamber and discharged through the vertical rod. Filter holes are provided at the lifting plate at the bottom of the material box, and the filter holes help the rice husk and dust to fall, and the overall dust generation amount of the device is very low.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

When there is more rice on the filter plate, the shelling rate increases, avoiding the situation that it is difficult to shell the increasing amount of rice on the filter plate. When there is less rice on the filter plate, the shelling rate returns to normal, thus avoiding the situation that the rice on the filter plate shakes and is difficult to shell during shelling.

[0020] 4. By setting up the feeding mechanism, the present invention achieves controlling the feeding amount according to the amount of rice on the filter plate. Thus, when there is more rice on the filter plate, the deformation amplitude of the annular airbag becomes larger, making the feeding port of the feeding pipe smaller and reducing the feeding amount.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Example 1

[0037] The present invention provides a technical solution: a rice hulling device, including a load-bearing plate 1, a hulling machine housing 2, a blower 11 and a feeding pipe 21. The hulling machine housing 2 and the blower 11 are both fixedly connected to the load-bearing plate 1. The blower 11 is fixedly communicated with the hulling machine housing 2 through a blowing pipe 12. The hulling machine housing 2 is fixedly communicated with the feeding pipe 21. A fixing rod 35 is fixedly connected to the hulling machine housing 2. A matching component 4 is provided on the fixing rod 35. A second telescopic rod 36 is fixedly connected to the matching component 4. A filter plate 3 is fixedly connected to the second telescopic rod 36. A first spiral plate 31 is fixedly connected to the filter plate 3. A second spiral plate 32 is provided on the hulling machine housing 2. The second spiral plate 32 cooperates with the first spiral plate 31. A matching mechanism for driving the cooperation between the second spiral plate 32 and the first spiral plate 31 is provided on the load-bearing plate 1.

[0038] By providing the blower 11 and the blowing pipe 12, the rice hulls are blown away, avoiding the effect of the rice hulls being mixed with the rice.

[0039] By providing the feeding pipe 21, the unhulled rice enters the hulling machine housing 2 through the feeding pipe 21.

[0040] Through the cooperation of the matching component 4 and the matching mechanism, the first spiral plate 31 reciprocally moves along the front-back, left-right directions towards the second spiral plate 32, so that the unhulled rice between the first spiral plate 31 and the second spiral plate 32 is hulled. The hulled rice falls along the filter holes on the filter plate 3. This hulling method can make the rice receive force in all directions and avoid the effect of the traditional mechanical stirring type crushing the rice during hulling.

[0041] The matching mechanism includes a first rotating rod 5 rotatably connected to the hulling machine housing 2. The fixing rod 35 passes through the first rotating rod 5. A connecting block 55 is fixedly connected to the first rotating rod 5. A first telescopic rod 52 is fixedly connected to the connecting block 55. The end of the first telescopic rod 52 away from the connecting block 55 is rotatably connected to the filter plate 3. A driving component is provided on the first rotating rod 5.

[0042] The first rotating rod 5 and the fixing rod 35 are coaxial, and the first rotating rod 5 is fixedly connected with the first telescopic rod 52 through the connecting block 55, so that through the driving component, the first telescopic rod 52 rotates eccentrically.

[0043] The matching component 4 includes a first coupling block 41, a cross-shaped clamping block 42, and a second coupling block 45. The first coupling block 41 is fixedly connected to the second telescopic rod 36, the second coupling block 45 is fixedly connected to the fixed rod 35, and both ends of the cross-shaped clamping block 42 are fixedly connected with a first convex block 43 and a second convex block 44 respectively. One end of the first coupling block 41 away from the second telescopic rod 36 is provided with a sliding groove and is in limit sliding connection with the first convex block 43 through the sliding groove. One end of the second coupling block 45 away from the fixed rod 35 is provided with a sliding groove and is in limit sliding connection with the second convex block 44 through the sliding groove.

[0044] Since the first telescopic rod 52 drives the filter plate 3 to perform an eccentric motion, through the cooperation of the first coupling block 41, the cross-shaped clamping block 42, and the second coupling block 45, position compensation is achieved, so that the filter plate 3 will not interfere, and thus the filter plate 3 drives the first spiral plate 31 to reciprocally slide along the first convex block 43 and the second convex block 44, so that the first spiral plate 31 and the second spiral plate 32 reciprocally contact in the front, back, left, and right directions, so as to quickly hull the rice and avoid the effect of the rice being broken during hulling.

[0045] The driving component includes a motor 7 fixedly connected to the hulling machine housing 2 and a first support plate 65. The output end of the motor 7 is fixedly connected with a rotating shaft 71. The rotating shaft 71 penetrates through the first support plate 65. A first bevel gear 72 is fixedly connected to the rotating shaft 71. A connecting plate 73 is rotatably connected to the rotating shaft 71. A second rotating rod 74 is rotatably connected to the connecting plate 73. A second bevel gear 75 and a round wheel 76 are fixedly connected to the second rotating rod 74. The second bevel gear 75 meshes with the first bevel gear 72.

[0046] The driving component further includes a spline 51 fixedly connected to the first rotating rod 5. The first rotating rod 5 is slidably connected with a frustum wheel 53 through the spline 51. The frustum wheel 53 is in transmission connection with the round wheel 76. A first spring 54 is sleeved on the first rotating rod 5. Both ends of the first spring 54 abut against the frustum wheel 53 and the hulling machine housing 2 respectively.

[0047] When the motor 7 is started, the rotating shaft 71 rotates, so that the first bevel gear 72 thereon rotates. Since the first bevel gear 72 meshes with the second bevel gear 75, the second bevel gear 75 rotates, so that the second rotating rod 74 drives the round wheel 76 to rotate. Since the round wheel 76 is in transmission connection with the frustum wheel 53, the frustum wheel 53 drives the first rotating rod 5 to rotate, so as to achieve the effect of driving the first rotating rod 5 to rotate and the first telescopic rod 52 to perform an eccentric motion.

[0048] Embodiment 2

[0049] It is basically the same as the first embodiment, and furthermore: a placing assembly is provided on the load-bearing plate 1. The placing assembly includes a rice box 13 and a rice husk box 14 fixedly connected to the load-bearing plate 1. Both the rice box 13 and the rice husk box 14 are in contact with the hulling machine housing 2. One end of the hulling machine housing 2 facing the rice box 13 is provided with a rice discharge port 22, and one end of the hulling machine housing 2 facing the rice husk box 14 is provided with a rice husk discharge port 23. A receiving plate 24 matching the rice discharge port 22 is provided on the hulling machine housing 2.

[0050] By providing the receiving plate 24, the hulled rice falls on the receiving plate 24. Since the receiving plate 24 is inclined, the rice slides along the inclined surface of the receiving plate 24 in the direction of the rice discharge port 22 and then slides into the rice box 13.

[0051] By providing the rice husk discharge port 23, when the hulled rice and rice husks slide down, through the blower 11 and the blowing air pipe 12, the rice husks are blown out along the rice husk discharge port 23 and blown into the rice husk box 14.

[0052] Embodiment Three

[0053] It is basically the same as the second embodiment, and furthermore: an adaptive mechanism for controlling the hulling rate according to the amount of rice on the filter plate 3 is provided on the load-bearing plate 1. The adaptive mechanism includes a second spring 37 sleeved on the second telescopic rod 36. The two ends of the second spring 37 are respectively abutted against the second telescopic rod 36 and the filter plate 3. A sliding rod 6 is slidably connected to the receiving plate 24. The sliding rod 6 abuts against the filter plate 3. One end of the sliding rod 6 away from the filter plate 3 is fixedly connected with a wedge block 61. The wedge block 61 abuts against the connecting plate 73. A baffle 63 is fixedly connected to the sliding rod 6. A third spring 62 is sleeved on the sliding rod 6. The two ends of the third spring 62 are respectively fixedly connected to the receiving plate 24 and the baffle 63.

[0054] When there is more rice on the filter plate 3, the weight of the filter plate 3 increases, causing the filter plate 3 to slide downwards, so that the second telescopic rod 36 contracts. Since the filter plate 3 abuts against the sliding rod 6, the sliding rod 6 slides downwards synchronously, and thus the wedge block 61 slides downwards. Since the wedge block 61 abuts against the connecting plate 73, the connecting plate 73 and the round wheel 76 slide towards the direction close to the conical wheel 53, so that the conical wheel 53 slides downwards, making the diameter of the mating surface of the round wheel 76 and the conical wheel 53 smaller, and increasing the rotation speed of the conical wheel 53. Thus, when there is more rice on the filter plate 3, the hulling rate increases, avoiding the effect that it is difficult to hull the increasing amount of rice on the filter plate 3.

[0055] When there is less rice on the filter plate 3, the elastic force of the second spring 37 is released, causing the filter plate 3 to slide upward, so that the second telescopic rod 36 extends, and then the elastic force of the third spring 62 is released, causing the sliding rod 6 to slide upward synchronously, so that the wedge block 61 slides upward, and then the connecting plate 73 and the round wheel 76 slide away from the conical wheel 53, and the elastic force of the first spring 54 is released, so that the conical wheel 53 slides upward, increasing the diameter of the mating surface between the round wheel 76 and the conical wheel 53, and restoring the rotation speed of the conical wheel 53 to normal. Thus, when there is less rice on the filter plate 3, the shelling rate is restored to normal.

[0056] By setting the adaptive mechanism, the shelling rate is controlled according to the amount of rice on the filter plate 3. When there is more rice on the filter plate 3, the shelling rate increases, avoiding the difficulty of shelling when there is more and more rice on the filter plate 3. When there is less rice on the filter plate 3, the shelling rate is restored to normal, thus avoiding the difficulty of shelling due to shaking when the rice on the filter plate 3 is shelled.

[0057] The adaptive mechanism further includes a second support plate 77 fixedly connected to the shell 2 of the shelling machine. An arc-shaped groove 78 is formed in the second support plate 77. The arc-shaped groove 78 is slidably connected to the end of the connecting plate 73 away from the rotating shaft 71. A fourth spring 79 is placed in the arc-shaped groove 78. Both ends of the fourth spring 79 are fixedly connected to the arc-shaped groove 78 and the connecting plate 73 respectively.

[0058] By setting the arc-shaped groove 78, the connecting plate 73 is limited, avoiding the effect that the connecting plate 73 rotates with the rotating shaft 71.

[0059] By setting the fourth spring 79, the effect of assisting the connecting plate 73 to reset is achieved.

[0060] The adaptive mechanism further includes a sliding groove 33 formed in the shell 2 of the shelling machine. The sliding groove 33 is slidably connected to the second spiral plate 32. A fifth spring 34 is placed in the sliding groove 33. Both ends of the fifth spring 34 are fixedly connected to the sliding groove 33 and the second spiral plate 32 respectively.

[0061] By setting the sliding groove 33, the second spiral plate 32 can slide along the sliding groove 33.

[0062] By setting the fifth spring 34, when the first spiral plate 31 slides downward, the elastic force of the fifth spring 34 is released, so that the first spiral plate 31 and the second spiral plate 32 can still cooperate. When the first spiral plate 31 slides upward, the second spiral plate 32 slides upward synchronously, so that the first spiral plate 31 and the second spiral plate 32 can always cooperate.

[0063] Embodiment 4

[0064] It is basically the same as Embodiment 3, and further: a feeding mechanism for controlling the feeding amount according to the amount of rice on the filter plate 3 is provided on the hulling machine housing 2. The feeding mechanism includes a piston cylinder 8 fixedly connected to the hulling machine housing 2. A sealing plug 83 is slidably connected to the piston cylinder 8. A piston rod 81 is fixedly connected to the sealing plug 83. A resisting block 82 is fixedly connected to the piston rod 81. The resisting block 82 abuts against the frustum wheel 53. A sixth spring 84 is sleeved on the piston rod 81. Two ends of the sixth spring 84 are respectively fixedly connected to the sealing plug 83 and the piston cylinder 8. A connecting pipe 85 is fixedly communicated with the piston cylinder 8. An annular airbag 86 is fixedly connected inside the feeding pipe 21. The annular airbag 86 is fixedly communicated with one end of the connecting pipe 85 away from the piston cylinder 8.

[0065] When there is more rice on the filter plate 3, at this time the frustum wheel 53 slides downward. Since the frustum wheel 53 abuts against the resisting block 82, the resisting block 82 slides downward, so that the piston rod 81 and the sealing plug 83 slide downward, making the gas in the piston cylinder 8 be conveyed to the annular airbag 86 through the connecting pipe 85, thereby making the deformation amplitude of the annular airbag 86 become larger, making the feed inlet of the feeding pipe 21 smaller, and thus achieving the effect of reducing the feeding amount.

[0066] When there is less rice on the filter plate 3, at this time the frustum wheel 53 slides upward, and the elastic force of the sixth spring 84 is released, making the piston rod 81 and the sealing plug 83 slide upward. Thus, the gas in the annular airbag 86 is conveyed to the piston cylinder 8 through the connecting pipe 85, thereby making the deformation amplitude of the annular airbag 86 return to normal, making the feed inlet of the feeding pipe 21 return to normal, and achieving the effect of making the feeding amount return to normal.

[0067] By setting the feeding mechanism, the feeding amount is controlled according to the amount of rice on the filter plate 3. Thus, when there is more rice on the filter plate 3, the deformation amplitude of the annular airbag 86 becomes larger, making the feed inlet of the feeding pipe 21 smaller and the feeding amount reduced. When there is less rice on the filter plate 3, the deformation amplitude of the annular airbag 86 returns to normal, making the feeding amount return to normal.

[0068] Working principle: For this rice hulling device, when in use, by setting the hair dryer 11 and the air blowing pipe 12, the rice husks are blown away, avoiding the effect of the rice husks being mixed with the rice.

[0069] By setting the feeding pipe 21, the unhulled rice can enter the hulling machine housing 2 through the feeding pipe 21.

[0070] Through the cooperation of the matching component 4 and the matching mechanism, the first spiral plate 31 moves reciprocatingly toward the second spiral plate 32 along the front-rear and left-right directions, so that the unhusked rice between the first spiral plate 31 and the second spiral plate 32 is husked, and the husked rice falls along the filter holes on the filter plate 3. This husking method can make the rice be subjected to force in all directions, and avoids the effect of breaking the rice during husking by the traditional mechanical stirring method.

[0071] The first rotating rod 5 is coaxial with the fixed rod 35 , and the first rotating rod 5 is fixedly connected to the first telescopic rod 52 via a connecting block 55 , so that the first telescopic rod 52 is eccentrically rotated by the driving assembly.

[0072] Since the first telescopic rod 52 drives the filter plate 3 to perform eccentric movement, position compensation is achieved through the cooperation of the first coupling block 41, the cross block 42 and the second coupling block 45, so that the filter plate 3 will not interfere with each other, so that the filter plate 3 drives the first spiral plate 31 to slide back and forth along the first protrusion 43 and the second protrusion 44, so that the first spiral plate 31 and the second spiral plate 32 reciprocate back and forth and left and right to contact each other, so that the rice can be husked quickly and the effect of rice being broken during husking is avoided.

[0073] Start the motor 7, the rotating shaft 71 rotates, thereby the first bevel gear 72 thereon rotates, and since the first bevel gear 72 is meshed with the second bevel gear 75, the second bevel gear 75 rotates, so that the second rotating rod 74 drives the circular wheel 76 to rotate, and since the circular wheel 76 is connected with the frustum wheel 53, the frustum wheel 53 drives the first rotating rod 5 to rotate, thereby achieving the effect of driving the first rotating rod 5 to rotate and the first telescopic rod 52 to make eccentric motion.

[0074] By providing the receiving plate 24 , the hulled rice falls on the receiving plate 24 . Since the receiving plate 24 is inclined, the rice slides along the inclined surface of the receiving plate 24 toward the rice discharge port 22 , and then slides into the rice box 13 .

[0075] By setting the rice husk discharge port 23, when the hulled rice and the rice husk slide downward, the rice husk can be blown out along the rice husk discharge port 23 and blown into the rice husk box 14 through the hair dryer 11 and the air blow pipe 12.

[0076] When there is more rice on the filter plate 3, the weight of the filter plate 3 increases, causing the filter plate 3 to slide downward, thereby causing the second telescopic rod 36 to contract. Since the filter plate 3 abuts against the sliding rod 6, the sliding rod 6 slides downward synchronously, and thus the wedge block 61 slides downward. Since the wedge block 61 abuts against the connecting plate 73, the connecting plate 73 and the round wheel 76 slide in the direction close to the conical wheel 53, and thus the conical wheel 53 slides downward, causing the diameter of the mating surface of the round wheel 76 and the conical wheel 53 to become smaller, and causing the rotation speed of the conical wheel 53 to increase. As a result, when there is more rice on the filter plate 3, the shelling rate increases, avoiding the situation that it becomes increasingly difficult to shell the rice on the filter plate 3.

[0077] When there is less rice on the filter plate 3, the elastic force of the second spring 37 is released, causing the filter plate 3 to slide upward, thereby causing the second telescopic rod 36 to extend. As a result, the elastic force of the third spring 62 is released, causing the sliding rod 6 to slide upward synchronously, and thus the wedge block 61 slides upward. As a result, the connecting plate 73 and the round wheel 76 slide in the direction away from the conical wheel 53, and the elastic force of the first spring 54 is released. Thus, the conical wheel 53 slides upward, causing the diameter of the mating surface of the round wheel 76 and the conical wheel 53 to become larger, and causing the rotation speed of the conical wheel 53 to return to normal. As a result, when there is less rice on the filter plate 3, the shelling rate returns to normal.

[0078] By setting the adaptive mechanism, the shelling rate is controlled according to the amount of rice on the filter plate 3. When there is more rice on the filter plate 3, the shelling rate increases, avoiding the situation that it becomes increasingly difficult to shell the rice on the filter plate 3. When there is less rice on the filter plate 3, the shelling rate returns to normal, thereby avoiding the situation that the rice on the filter plate 3 shakes and is difficult to shell during the shelling process.

[0079] By setting the arc-shaped groove 78, the connecting plate 73 is limited, avoiding the situation that the connecting plate 73 rotates with the rotating shaft 71.

[0080] By setting the fourth spring 79, the effect of assisting the connecting plate 73 to reset is achieved.

[0081] By setting the sliding groove 33, the effect that the second spiral plate 32 can slide along the sliding groove 33 is achieved.

[0082] By setting the fifth spring 34, when the first spiral plate 31 slides downward, the elastic force of the fifth spring 34 is released. Thus, the first spiral plate 31 and the second spiral plate 32 can still cooperate. When the first spiral plate 31 slides upward, the second spiral plate 32 slides upward synchronously, thereby ensuring that the first spiral plate 31 and the second spiral plate 32 can always cooperate.

[0083] When there is a large amount of rice on the filter plate 3, the frustum wheel 53 slides downward at this time. Since the frustum wheel 53 abuts against the abutting block 82, the abutting block 82 slides downward, so that the piston rod 81 and the sealing plug 83 slide downward, and the gas in the piston cylinder 8 is conveyed to the annular airbag 86 through the connecting pipe 85, so that the deformation amplitude of the annular airbag 86 becomes larger, the feeding port of the blanking pipe 21 becomes smaller, and the blanking amount is reduced as a result.

[0084] When there is less rice on the filter plate 3, the frustum wheel 53 slides upward at this time, and the elastic force of the sixth spring 84 is released, so that the piston rod 81 and the sealing plug 83 slide upward. As a result, the gas in the annular airbag 86 is conveyed to the piston cylinder 8 through the connecting pipe 85, so that the deformation amplitude of the annular airbag 86 returns to normal, the feeding port of the blanking pipe 21 returns to normal, and the blanking amount returns to normal.

[0085] By setting the blanking mechanism, the blanking amount is controlled according to the amount of rice on the filter plate 3. Thus, when there is a large amount of rice on the filter plate 3, the deformation amplitude of the annular airbag 86 becomes larger, the feeding port of the blanking pipe 21 becomes smaller, and the blanking amount is reduced. When there is less rice on the filter plate 3, the deformation amplitude of the annular airbag 86 returns to normal, and the blanking amount returns to normal.

[0086] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
