Description

Technical Field

[0001] The invention relates to the field of rice milling devices, in particular to a high-efficiency and energy-saving rice milling machine. Background Art

[0002] Rice milling machine is an important equipment in grain processing. It is used to process grain raw materials such as paddy into rice. The rice milling machine can improve the efficiency of rice husking.

[0003] However, the existing rice milling machine feeding device is often designed to be relatively simple. Most of them adopt the ordinary feeding hopper direct feeding method, which pours the rice into the husking structure at one time through the grain's own gravity. Due to the excessive feeding amount, the husking component will be overloaded, increasing the wear and energy consumption of the equipment, and may also cause incomplete husking. At the same time, the sorting components of the existing rice mills mainly use conveyor belts for transmission, and then use the vibration of the screen to separate the rice from the rice husk. Since the physical properties of the rice husk and the rice are slightly different, the rice husk is easy to stick to the rice during the sorting process, and it is easy for the rice to be mixed with the rice husk or the rice to be carried in the rice husk.

[0024] refer to Figure 1-5 The invention discloses an energy-efficient rice milling machine, comprising a machine base 1, a feeding component 2, a shelling component 3, a sorting component 4, a shelling outlet 5, a suction component 6 and a rice outlet 7. The components cooperate with each other to form a complete rice processing system. The machine base 1 is the supporting foundation of the whole rice milling machine and provides a stable installation platform for other components. The feeding component 2 is arranged at the top of the machine base 1 and is used to transport the rice to the shelling component 3. The shelling component 3 is arranged in the machine base 1 and is connected to the bottom of the feeding component 2, and can shell the rice. The sorting component 4 is arranged in the machine base 1 and is arranged below the shelling component 3, and can separate the rice husk and the rice after shelling to ensure the purity of the rice. The shelling outlet 5 is arranged at the top of the machine base 1 and is connected to the sorting component 4, and is used to discharge the separated rice husk. The suction component 6 forms a suction channel with the sorting component 4 and the shelling outlet 5, and uses airflow to assist in sorting and discharging the rice husk. The rice outlet 7 is arranged at the bottom of the sorting component 4, and can discharge the separated rice.

[0025] In some embodiments, the feed assembly 2 includes a feed hopper 21, a feed roller 22 and a plurality of nano-grooves 23. The feed hopper 21 is disposed on the top of the machine base 1 for storing and preliminarily conveying rice, the feed roller 22 is rotatably disposed below the feed hopper 21, a shelling assembly 3 is disposed below the feed roller 22, and the feed roller 22 is transmission-connected to the shelling assembly 3, and the rotation of the feed roller 22 can be driven by the power transmission of the shelling assembly 3, so as to realize the coordinated work of feeding and shelling. The feed roller 22 can be made of a material with good wear resistance and corrosion resistance, and can be made of high-strength alloy steel, and its surface is heat-treated and coated to improve the surface hardness and wear resistance. A plurality of nano-grooves 23 are arranged in a ring shape on the feed roller 22. The nano-grooves 23 can realize the temporary storage of rice on the feed roller 22, so that the rice can be transported at intervals and in a quantitative manner through the rotation of the feed roller 22, so that the rice can enter the shelling component 3 more evenly and stably. The size of the nano-grooves 23 can be designed according to actual needs to realize intermittent feeding while ensuring continuous shelling of the shelling component 3. A blocking plate is provided in the opposite direction of the rotation of the nano-groove 23 and the feed roller 22 to prevent the rice from falling when the feed roller 22 initially rotates, thereby improving the control accuracy of the feed. When the feed roller 22 rotates, when the nano-groove 23 rotates to the top of the feed roller 22, the rice in the feed hopper 21 will enter the nano-groove 23, and the rice will rotate with the feed roller 22 and be transported to the shelling component 3, avoiding the accumulation and blockage of the rice and improving the accuracy and efficiency of the feed. In some embodiments, guide plates may be provided on both sides of the feed roller 22. The guide plates are tilted to guide the rice grains that fall during the rotation of the feed roller 22 to the shelling assembly 3, thereby ensuring the moving track of the rice grains.

[0026] In some embodiments, the shelling assembly 3 includes a shelling motor 31, a first shelling roller 32, a second shelling roller 33, and a transmission member 34. The shelling motor 31 is a power source that provides power for the shelling process. The first shelling roller 32 is rotatably arranged below the feeding assembly 2 and is transmission-connected to the shelling motor 31, and is driven to rotate by the shelling motor 31. The second shelling roller 33 is arranged below the feeding assembly 2, and a shelling area is formed between the second shelling roller 33 and the first shelling roller 32. When the rice falls into the shelling area, the rice will be squeezed and rubbed between the second shelling roller 33 and the first shelling roller 32, so that the rice and the shell in the rice are subjected to forces of different directions and sizes, thereby realizing the shelling of the rice. The transmission member 34 is arranged between the first shelling roller 32 and the second shelling roller 33. The transmission between the first shelling roller 32 and the second shelling roller 33 can be realized through the power transmission of the transmission member 34.

[0027] In some embodiments, the first hulling roller 32 can be a rubber roller. Through the elastic effect of the first hulling roller 32, the impact force of the rice on the first hulling roller 32 can be reduced, ensuring that the rice falls into the hulling area. The second hulling roller 33 can be made of high-strength alloy steel and other materials with good wear resistance and corrosion resistance, and its surface is heat-treated and coated to improve the surface hardness and wear resistance. Through the elastic effect of the first hulling roller 32, the rice husk can be separated from the rice while protecting the rice to avoid hard contact to cause breakage of the rice, thereby improving the integrity of the rice.

[0028] In some embodiments, the transmission member 34 includes a driving gear 341, a driven gear 342 and a transfer gear 343. The driving gear 341 is coaxially sleeved on the first shelling roller 32, the driven gear 342 is coaxially sleeved on the second shelling roller 33, and the transfer gear 343 is rotatably arranged between the driving gear 341 and the driven gear 342, and is meshed with both the driving gear 341 and the driven gear 342. Through the transmission structure of the driving gear 341, the driven gear 342 and the transfer gear 343, the first hulling roller 32 and the second hulling roller 33 can rotate in opposite directions, so that the rice is more fully squeezed and rubbed in the hulling area, thereby improving the hulling efficiency. At the same time, by adjusting the transmission ratio among the driving gear 341, the driven gear 342 and the transfer gear 343, different rotation speeds of the driving gear 341 and the driven gear 342 can be achieved, so that the rice husk is subjected to squeezing forces and friction forces in two different directions and of different sizes. Through the rotation of the rice, part of the force of the driving gear 341 and the driven gear 342 acting on the rice husk is offset, so as to avoid the rice from being broken when the force is too large, thereby realizing the self-regulation function of the rice and improving the integrity rate of the rice.

[0029] In some embodiments, in order to control the feed amount and feed speed and avoid the accumulation and blockage of rice at the feed port, the shelling assembly 3 also includes an intermittent disk 35, an intermittent groove 36, a dial 37 and a lever 38. The intermittent disk 35 is coaxially sleeved on the feed roller 22. The feed roller 22 can be driven to rotate by the rotation of the intermittent disk 35. Multiple intermittent grooves 36 are annular and equidistantly arranged on the intermittent disk 35. The dial 37 is rotatably arranged below the intermittent disk 35 and is transmission-connected to the shelling motor 31. It can be transmission-connected through a pulley structure. The shelling motor 31 rotates to drive the dial 37 to rotate. The lever 38 is arranged on the side of the dial 37 close to the intermittent disk 35, and the lever 38 is plugged into the intermittent groove 36. When the shelling motor 31 drives the dial 37 to rotate, the lever 38 on the dial 37 will rotate periodically. When the lever 38 rotates to the top area of ​​the dial 37, the lever 38 will be inserted into the intermittent groove 36, driving the intermittent disk 35 to rotate intermittently, thereby making the feed roller 22 rotate intermittently. Through the intermittent rotation of the feed roller 22, the position of the nano-groove 23 in space can be intermittently adjusted, thereby realizing the quantitative transportation of rice, allowing the rice to enter the shelling area more evenly, avoiding the shelling component 3 from being overloaded due to excessive feeding, and also improving the quality and stability of rice shelling.

[0030] The rotation speed of the shelling motor 31, the transmission ratio of the transmission member 34, the rotation speed of the feed roller 22, the size and number of the nano grooves 23 are all obtained through calculation. While satisfying the shelling function of the shelling component 3, the feed amount of the feed roller 22 can be controlled, thereby achieving dynamic balance to realize continuous shelling of rice.

[0031] In some embodiments, in order to realize the centralized collection of paddy rice, rice and rice husks, a guide block can be arranged between the shelling component 3 and the sorting component 4, and a guide groove is arranged in the middle of the guide block. The cross section of the guide groove can be an isosceles trapezoid, thereby forming a guide slope in the guide block. The guide groove can cover the first shelling roller 32 and the second shelling roller 33, thereby ensuring that the rice that has been squeezed and rubbed can smoothly enter the sorting component 4, thereby realizing the sorting of rice and rice husks.

[0032] In some embodiments, the sorting assembly 4 includes a sorting barrel 41 and a sorting plate 42. The sorting barrel 41 is arranged below the sorting assembly 4 and is connected to the suction assembly 6. The top of the sorting barrel 41 is connected to the shell outlet 5, which can collect the husked rice and guide it out from the shell outlet 5 to achieve the husking of the rice. The bottom of the sorting barrel 41 is connected to the rice outlet 7 to collect the sorted rice. The sorting plate 42 is coaxially arranged in the sorting barrel 41 and can rotate in the sorting barrel 41. The sorting plate 42 can be coaxially fixed on the output shaft of the rotating motor. Using the principle of centrifugal action, when the sorting plate 42 rotates, due to the centrifugal force and the gravity of the material itself, the rice husk and the rice will move in different directions. The rice husk is relatively light and is more easily carried away by the airflow generated by the suction assembly 6 and discharged through the shell outlet 5; while the rice is relatively heavy and will slide along the inclined surface of the sorting plate 42 to the rice outlet 7, thereby realizing the distinction between the rice husk and the rice. The inner bottom wall of the sorting cylinder 41 can be an inclined surface, and the end of the sorting cylinder 41 connected to the rice outlet 7 is higher than the end of the sorting cylinder 41 away from the rice outlet 7. Through the inclined surface, the rice falling on the inner bottom wall of the sorting cylinder 41 can be moved toward the rice outlet 7 under its own gravity, which is convenient for collecting the rice.

[0033] In some embodiments, the edge of the sorting plate 42 may be higher than the center point of the sorting plate 42. This design allows the husked material to form an inclined distribution state on the sorting plate 42, which can increase the surface area of ​​the sorting plate 42, extend the movement path of the rice on the sorting plate 42, and improve the uniformity of the distribution of the rice, rice husk, and rice on the sorting plate 42. At the same time, through the action of the suction component 6, an air negative pressure area is formed in the sorting plate 42, thereby accelerating the separation between the rice husk and the rice. And through the rotation of the sorting plate 42, the rice can be thrown out of the sorting plate 42 and collide with the inner wall of the sorting cylinder 41 to achieve the separation of rice and rice husk in the unhusked rice. At the same time, the distance between the rice husk and the shell outlet 5 can be extended, and the uniformity of the distribution of the rice husk and the rice in space can be increased, thereby improving the suction effect of the suction component 6 on the rice husk, and then improving the sorting effect of the rice husk and the rice.

[0034] In some embodiments, the sorting component 4 further includes a plurality of paddle rings 43, a plurality of rice leaking openings 44, a rice leaking ring groove 45, a rice leaking channel 46, a rice collecting tube 47, and a rice collecting channel 48. The plurality of paddle rings 43 are arranged at equal intervals on the top surface of the sorting disk 42. The paddle ring 43 can be a thin sheet made of a flexible material such as rubber, and can swing to a certain extent while the sorting disk 42 rotates. A plurality of rice leaking openings 44 are arranged between two adjacent paddle rings 43. The plurality of rice leaking openings 44 can allow the separated rice to enter, thereby achieving the separation of rice and paddy. The rice shells are separated by a rice leaking groove 45 at the bottom of the sorting plate 42. The rice leaking groove 45 is connected to the plurality of rice leaking ports 44 through a rice leaking channel 46. The rice in the plurality of rice leaking ports 44 can enter the rice leaking groove 45 through the rice leaking channel 46. A rice collecting pipe 47 is arranged at one side of the machine base 1. A rice collecting channel 48 is obliquely arranged in the machine base 1 and is arranged between the rice collecting pipe 47 and the rice leaking groove 45. The rice in the rice leaking groove 45 can be collected in the rice collecting pipe 47 through the rice collecting channel 48, thereby being led out of the rice mill to realize the collection of rice.

[0035] Specifically, the rice with rice husks falling into the sorting component 4 will be cracked by the squeezing and friction between the first hulling roller 32 and the second hulling roller 33 in the early stage. The rice with rice husks follows the rotation of the sorting disk 42. During the rotation, it is subjected to the centrifugal force and moves toward the edge of the sorting disk 42. In this process, the rice with rice husks will collide with the paddle ring 43. The rice husks will be separated from the rice by the forces of different directions and sizes. At the same time, the paddle ring 43 will swing to a certain extent during the rotation. Multiple paddle rings 43 swing together and will form a circle on the surface of the sorting disk 42. The wind force of a certain strength is formed on the surface, which will blow the rice husks falling on the sorting disk 42, and under the action of the negative pressure around the sorting disk 42, the separation of the rice husks and the rice is accelerated, and the cleanliness of the rice at the husk outlet 5 is improved. At the same time, during the rotation process, the rice will fall into the rice leakage port 44, enter the rice leakage ring groove 45 through the rice leakage channel 46, and then rotate with the sorting disk 42. When it rotates to the rice collection channel 48 close to the opening on one side of the sorting disk 42, the rice in the rice leakage ring groove 45 will enter the rice collection channel 48 under the action of centrifugal force, and slide out from the rice collection tube 47 under the action of its own gravity and inertia, so as to realize the collection of rice.

[0036] Through the above structure of the sorting component 4, the viscosity between rice and rice husk can be reduced, and the separation between rice and rice husk can be accelerated under the action of wind force generated by the paddle ring 43, thereby reducing the probability of rice husk being mixed into rice and improving the cleanliness of rice. The second channel for collecting rice is realized through the rice leaking port 44, the rice leaking ring groove 45, the rice leaking channel 46, the rice collecting tube 47, and the rice collecting channel 48, thereby improving the collection speed of rice and avoiding the aggregation of rice on the sorting plate 42, further reducing the viscosity between rice and rice husk, and improving the separation rate of rice and rice husk.

[0037] In some embodiments, the paddle ring 43 includes a plurality of paddles, which are arranged in a ring shape on the top surface of the sorting disk 42, and a gap is left between two adjacent paddles. The plurality of unconnected paddles can improve the flexibility of the paddles, so that when the paddle ring 43 rotates with the sorting disk 42, the paddles are easier to swing, thereby improving the sorting effect of the paddle ring 43 on the rice husk. The plurality of paddles between two adjacent paddle rings 43 can be staggered, which can extend the path for the rice to move to the edge of the sorting disk 42, increase the uniformity of the distribution of the rice on the sorting disk 42, further improve the separation degree of the rice from the rice husk, and improve the cleanliness of the rice.

[0038] In some embodiments, the suction assembly 6 includes a hair dryer and an exhaust fan. The hair dryer is arranged at the bottom of the sorting assembly 4. The exhaust port of the exhaust fan is connected to the shell outlet 5 and can be connected through a pipeline. A suction channel is connected between the hair dryer and the exhaust fan. The suction channel is a flow channel connecting the sorting cylinder 41 and the shell outlet 5. The hair dryer blows air into the sorting cylinder 41 to form an upward airflow field in the sorting cylinder 41. The exhaust fan extracts the airflow in the sorting cylinder 41 through the suction channel to form a negative pressure at the shell outlet 5. This airflow circulation system can effectively extract the rice husk from the sorting assembly 4 and discharge it through the shell outlet 5. It also helps to improve the sorting effect and better separate the rice husk and rice.

[0039] In some embodiments, the hair dryer can be a blower, which can cover the sorting plate 42, thereby cooperating with the exhaust fan to form a wind curtain wall around the sorting plate 42 to prevent the rice husks from leaving the sorting plate 42 and the range of the sorting plate 42, thereby facilitating the collection of the rice husks. The output shaft of the blower motor can be extended and fixed coaxially with the sorting plate 42. By rotating the blower motor, the blowing effect can be achieved while driving the sorting plate 42 to rotate, thereby reducing the number of equipment and saving energy.

[0040] The specific working principle is as follows: During the specific operation, the operator pours the rice to be processed into the feed hopper 21 located at the top of the machine base 1, and the feed hopper 21 plays the role of storing and preliminarily conveying the rice. The shelling motor 31 rotates, driving the dial 37 to rotate. The lever 38 on the dial 37 rotates periodically. When the lever 38 rotates to the top area of ​​the dial 37, it will be inserted into the intermittent groove 36 on the intermittent disk 35, driving the intermittent disk 35 to rotate intermittently, and then the feed roller 22 rotates intermittently. When the nano groove 23 rotates to the top of the feed roller 22, the rice in the feed hopper 21 will naturally fall into the nano groove 23, realizing the temporary storage of the rice on the feed roller 22. The rice entering the nano groove 23 follows the feed roller 22 to rotate to the bottom. Under the action of gravity, the rice will gradually enter the shelling component 3 to realize the quantitative conveying of the rice.

[0041] After the feeding stage, the rice enters the shelling assembly 3 for shelling. The rotation of the shelling motor 31 drives the first shelling roller 32 to rotate, and at the same time, through the transmission of the transmission member 34, the second shelling roller 33 rotates in the opposite direction following the first shelling roller 32. When the rice falls from the feeding assembly 2 into the shelling area, it is squeezed and rubbed between the second shelling roller 33 and the first shelling roller 32, so that the rice husk and rice are separated in the shelling area.

[0042] The mixture after hulling in the rice husk and rice separation stage enters the sorting component 4 for separation of rice husk and rice. When the sorting disc 42 rotates, the rice husk and rice move in different directions under the action of centrifugal force and their own gravity by utilizing the principle of centrifugal action. A hair dryer is arranged at the bottom of the sorting component 4 to blow air into the sorting cylinder 41 so that an upward airflow field is formed in the sorting cylinder 41. The air outlet of the exhaust fan is connected to the shell outlet 5, and the airflow in the sorting cylinder 41 is extracted through the suction channel to form a negative pressure at the shell outlet 5. Therefore, when the sorting disc 42 rotates, the rice husk is relatively light and is more easily taken away by the airflow generated by the suction component 6; while the rice is relatively heavy and will slide along the inclined surface of the sorting disc 42 to the rice outlet 7, so that the rice husk and rice are better separated. The multiple friction bumps arranged at equal intervals on the top surface of the sorting disc 42 also play an important role. The rice with rice husk falling into the sorting assembly 4 will be cracked by the force due to the squeezing and friction between the first husking roller 32 and the second husking roller 33 in the early stage. As the sorting disk 42 rotates, the rice with rice husk follows the rotation, and is subjected to the centrifugal force during the rotation process, and moves toward the edge of the sorting disk 42. In this process, the rice with rice husk will collide with the friction convex points, and the rice husk will be separated from the rice by the forces of different directions and sizes, further realizing the separation of rice husk and rice, and improving the cleanliness of rice at the husk outlet 5.

[0043] After the final product output is separated by the sorting component 4, the rice husk is discharged through the husk outlet 5 and can be collected for other purposes, such as feed or fuel. The separated rice is discharged from the rice outlet 7 to become finished rice for people to eat. The entire rice processing process is efficiently completed under the synergistic effect of each component, realizing the transformation of rice from raw materials to finished rice. At the same time, through the innovative design and optimized coordination of each component, the purpose of high efficiency and energy saving is achieved.
