Description

Technical Field

[0001] This invention relates to the field of grain processing technology, specifically to an energy-saving integrated rice hulling and milling machine. Background Technology

[0002] In the grain processing industry, grain milling technology is constantly evolving. Hulling and rice milling are key processes in rice processing, and the performance of the equipment used significantly impacts processing efficiency, rice quality, and energy consumption. Traditionally, hulling and rice milling machines are mostly independent single units. Operators must manually transfer the hulled brown rice to the rice milling machine, a process that is not only cumbersome but also greatly reduces processing efficiency. While combined hulling and milling machines have emerged on the market to address this issue, existing combined machines still have many shortcomings, particularly in terms of energy efficiency.

[0003] Existing rice hulling and milling machines generally employ a single power transmission system, where the same motor drives both the hulling roller and the milling roller simultaneously through a complex transmission mechanism. This transmission method makes it difficult to precisely adjust power output according to the load requirements of different processes in hulling and milling, often resulting in significant energy waste. For example, when the load on the hulling process is low, the motor still needs to maintain a high output power to meet the demands of the milling process, leading to a substantial increase in energy consumption per unit of output. Moreover, traditional motors themselves have low energy efficiency, further exacerbating the high energy consumption problem of the equipment, which is inconsistent with the current trend of green and energy-saving industrial development.

[0004] At the same time, the existing equipment is bulky, loosely structured, and occupies a lot of space, which cannot meet the needs of small processing plants or places with limited space, and it is also inconvenient to move.

[0005] In the rice milling process, existing technologies make it difficult to precisely control the milling pressure and temperature rise, which can easily lead to an increase in broken rice, reduce rice quality and yield, resulting in low raw material utilization and indirectly increasing processing costs and energy consumption.

[0006] In addition, most existing rice hulling and milling machines lack intelligent adjustment and control functions, making it difficult to automatically optimize the processing according to different rice varieties, moisture content and other parameters. They have poor adaptability and cannot achieve dynamic optimization of energy consumption.

[0007] Finally, the poor coordination between the various units of the existing rice hulling machine leads to a decrease in rice quality and yield due to the vibration between them, thereby increasing processing costs and energy consumption.

[0008] In summary, the existing technology has the following drawbacks: a single power transmission system will cause a large waste of energy; it occupies a large space and is not easy to move; the existing technology is difficult to control the rice milling pressure and temperature rise accurately, resulting in high energy consumption; it has poor adaptability and cannot achieve dynamic optimization of energy consumption; and the synergistic effect is poor, and the vibration between each other will lead to a decrease in rice quality and rice yield, thereby increasing processing costs and energy consumption. Summary of the Invention

[0009] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an energy-saving integrated rice hulling and milling machine. It features multiple power transmissions, energy efficiency, a compact and easily movable structure, precise control of milling pressure and temperature rise, strong adaptability, dynamic energy consumption optimization, good synergistic effects, and improved rice milling efficiency. This solves the problems of existing technologies, such as energy waste from single-power transmissions, large footprint making movement difficult, difficulty in precisely controlling milling pressure and temperature rise leading to high energy consumption, poor adaptability preventing dynamic energy consumption optimization, and poor synergistic effects resulting in reduced rice quality and yield, thus increasing processing costs and energy consumption.

The bottom of the lifting column is rotatably provided with rollers, and the top of the lifting column is fixed within the support legs with a screw. The end of the screw away from the lifting column is connected to the rotating handle via a helical gear.

[0015] Preferably, the cylinder includes an outer shell cylinder that is sealed without gaps on the outside and an inner screen cylinder with filter holes on the inside.

[0016] Preferably, the rice hulling assembly includes a feeding channel, the end of which is connected between two rice hulling rollers. The two rice hulling rollers rotate at different speeds. The material enters the rice hulling rollers from the feeding channel, is crushed, and then enters the discharge channel. The rice hulling assembly is also equipped with a blower box.

[0020] (III) Beneficial Effects Compared with the prior art, the present invention provides an energy-saving integrated rice hulling and milling machine, which has the following beneficial effects: 1. This energy-saving integrated rice hulling and milling machine, by driving the hulling component, paddy-brown separator component, and rice milling component with separate hulling motors, paddy-brown motors, and rice milling motors, can more efficiently control the power of each component, thereby improving energy utilization and achieving high efficiency and energy saving. The paddy-brown separator component and rice milling component are movably mounted on the main frame, and their lifting and lowering are controlled separately by lifting components. First, when the paddy-brown separator component and rice milling component descend to the bottom, a locking mechanism secures the paddy-brown frame and rice milling component. The frame is fixed to the crossbeam of the main frame, which improves stability when not in use. Secondly, when the hulling and rice milling components rise, they detach from the main frame. During operation, the vibrations generated by the hulling, hulling, and rice milling components do not affect each other, improving the milling effect and avoiding energy waste. Finally, when either the hulling or rice milling component rises to the top, the main frame is lifted off the ground by the limiting boss, and the rollers at the bottom of the lifting component drive the combined rice machine to move.

[0021] 2. This energy-saving integrated rice hulling and milling machine, by setting the rice milling machine cylinder to a horizontally sliding structure, uses a cooperating component to transmit the vibration of the paddy separator to the rice milling machine cylinder, improving the mobility of brown rice and the discharge rate of debris inside the rice milling machine. At the same time, the cooperating component can also provide a buffering force for the rice milling machine. Furthermore, since the rice milling component is equipped with a lifting component, the height of the rice milling component can be changed using the lifting component. During the change of the height of the rice milling component, the distance between the rotation center of the rice milling machine cylinder and the rotating plate can also be changed, thereby adjusting the transmission rate of the paddy separator to the rice milling machine vibration.

[0022] 3. This energy-saving integrated rice hulling and milling machine uses an elastic component as an air bladder. The airflow generated when the elastic component is squeezed is discharged into the paddy separator through the air pipe and air duct in the rotating plate. The airflow can improve the screening rate of the paddy separator. At the same time, the air bladder can also improve the buffering force between the rotating plate and the paddy separator and rice milling machine. Attached Figure Description

[0047] Example 1: This embodiment provides an energy-saving integrated rice hulling and milling machine, which has the following technical features.

[0048] Please see Figure 1-19 An energy-saving integrated rice hulling and milling machine includes a main frame 1, a rice hulling component 2 fixedly installed on the top of the main frame 1, a rice-brown separation component 3 and a rice milling component 4 movably installed in the middle and bottom of the main frame 1, respectively, and the rice hulling component 2, the rice-brown separation component 3 and the rice milling component 4 are driven by a rice hulling motor 21, a rice-brown separation motor 31 and a rice milling motor 41, respectively. The husk separating component 3 and the rice milling component 4 are supported by the husk frame 33 and the rice milling frame 43 respectively. The bottom of the support feet of the husk frame 33 and the rice milling frame 43 are provided with lifting components 6, which are used to control the lifting of the husk separating component 3 and the rice milling component 4 respectively. The bottom of the lifting components 6 is provided with rollers 62, and the side of the support feet of the husk frame 33 and the rice milling frame 43 is provided with limiting bosses 7. When the husk separating component 3 and the rice milling component 4 descend to the bottom, the husk frame 33 and the rice milling frame 43 are fixed to the crossbeam of the main frame 1 by the locking mechanism. When the husk separating component 3 and the rice milling component 4 rise, the husk separating component 3 and the rice milling component 4 are separated from the main frame 1. When either the husk separating component 3 or the rice milling component 4 rises to the top, the main frame 1 is lifted off the ground by the limiting boss 7.

[0049] Furthermore, the locking mechanism is a pin-type locking mechanism, including a pin seat fixed on the crossbeam of the main frame 1, and a movable pin installed on the support legs of the rice milling frame 33 and the rice hulling frame 43, which can be manually or spring-driven to extend and retract.

[0050] It should be noted that when the rice separating component 3 or the rice milling component 4 descends to the bottom, the frame support foot is in contact with the main frame crossbeam. At this time, the pin is aligned with the hole of the pin seat. Pushing the pin into the pin seat will lock the device. To unlock, pull out the pin.

[0051] Furthermore, another locking mechanism is also provided at the bottom of the limit boss 7 and the crossbeam of the main frame 1 to improve the stability of the main frame 1 after it is raised.

[0052] In an optional embodiment, the rice-coconut separation assembly 3 further includes a rice-coconut separator 32, a rice-coconut motor 31 fixed on the crossbeam of the rice-coconut frame 33, and the rice-coconut separator 32 horizontally slidably disposed on the crossbeam of the rice-coconut frame 33. The output shaft of the rice-coconut motor 31 drives the rice-coconut separator 32 to reciprocate through a rocker sliding mechanism. The rice milling assembly 4 also includes a rice milling machine 42, which includes a cylinder, a roller support plate 421 and a rice milling roller 422. The two roller support plates 421 and the rice milling motor 41 are fixed on the crossbeam of the rice milling frame 43. The output shaft of the rice milling motor 41 drives the rice milling roller 422 to rotate through a transmission connection. The two ends of the rice milling roller 422 are rotatably supported on the roller support plate 421, and the cylinder slides horizontally between the two roller support plates 421. The cylinders of the rice separator 32 and the rice milling machine 42 are connected by a coordinating component 5. When the rice separator 32 slides back and forth, the cylinder vibrates through the coordinating component 5.

[0053] It should be noted that the two ends of the cylinder are pressed against the inner side of the two roller support plates 421. The two roller support plates 421 are provided with horizontal grooves at the position of the cylinder, thereby restricting the cylinder to slide within the roller support plates 421. Furthermore, the length of the groove is limited to a fixed value, that is, when the cylinder slides to the outermost position, there is a gap between the inner side of the cylinder and the milling blades 4221 on the rice milling roller 422.

[0054] In an optional embodiment, the cooperating component 5 includes a rotating plate 51 rotatably mounted on the crossbeam of the main frame 1, a vibrating plate 326 fixed at the middle position of the bottom of the rice separator 32, the upper half of the rotating plate 51 and the vibrating plate 326 being connected by an elastic component 52, and the lower half of the rotating plate 51 being connected by an adhesive plate 53 through the elastic component 52, the adhesive plate 53 being attached to the outer wall of the rice milling machine 42 cylinder.

[0055] Furthermore, the collaborative component 5 includes two symmetrically arranged rotating plates 51.

[0056] Furthermore, the rotating plate 51 is equipped with an angle sensor and a pressure sensor.

[0057] It should be noted that the angle sensor can monitor the oscillation frequency of the rice milling machine 42 in real time, and the pressure sensor can detect the resistance when the rice milling machine 42 oscillates.

[0058] In an optional embodiment, the elastic component 52 is an airbag, an air supply pipe is provided inside the rotating plate 51, an air duct outlet 54 is provided at the top of the rotating plate 51, and a sieve plate air inlet 327 is provided at the bottom inside the rice separator 32, the sieve plate air inlet 327 is connected to the ventilation duct outlet 54 through a flexible hose.

[0059] Furthermore, a one-way air intake valve is provided on the elastic component 52, and a one-way exhaust valve is provided between the elastic component 52 and the air supply pipe.

[0060] Furthermore, an elastic component 52 is also provided with a spring to supplement the elastic force.

[0061] In an optional embodiment, the lifting assembly 6 includes a lifting column 61 slidably disposed within the support legs of the rice separating assembly 3 and the rice milling assembly 4. A roller 62 is rotatably disposed at the bottom of the lifting column 61, and a screw 63 is fixed at the top of the lifting column 61 within the support legs. The end of the screw 63 away from the lifting column 61 is connected to the rotating handle 64 via a helical gear.

[0062] In an optional embodiment, the cylinder includes an outer shell cylinder 423 that is sealed without gaps on the outside and an inner screen cylinder 424 with filter holes on the inside. The inner screen cylinder 424 and the outer shell cylinder 423 are fixedly connected together. A top support 4234 is provided on the top of the inner wall of the outer shell cylinder 423. The inner screen cylinder 424 is fixed on the top support 4234. A roller feed port 4231 is provided on the outside of the outer shell cylinder 423. The roller feed port 4231 penetrates the outer shell cylinder 423 and the inner screen cylinder 424. A roller discharge port 4211 is provided on the roller support plate 421. The material enters the inner screen cylinder 424 from the roller feed port 4231, is milled by friction by the rice milling roller 422, and is discharged through the roller discharge port 4211.

[0063] In an optional embodiment, the rice hulling assembly 2 includes a feeding channel 22, the end of which is connected between two rice hulling rollers 24. The two rice hulling rollers 24 rotate at different speeds. The material enters the rice hulling rollers 24 from the feeding channel 22, is crushed, and then enters the discharge channel 26. The rice hulling assembly 2 is also provided with a blower box 25. The airflow blown out of the blower box 25 blows the rice husks out from above the discharge channel 26, and the paddy rice and brown rice are discharged downward from the discharge channel 26.

[0064] Furthermore, the rice hulling motor 21 drives two rice hulling rollers 24 to rotate via a belt 211. One of the rice hulling rollers 24 is equipped with a gap adjustment mechanism 213, which is a hydraulic push device. The gap adjustment mechanism 213 pushes the rice hulling roller 24 to change the gap between the two rice hulling rollers 24. The belt 211 is also equipped with a tension roller 212 to maintain the tension of the belt 211.

[0065] It should be noted that paddy rice and brown rice are discharged into the paddy rice separator 32 from below the discharge channel 26.

[0066] In an optional embodiment, the rocker-slider mechanism of the output shaft of the rice separator 32 and the rice motor 31 includes a groove plate 321 fixed on the rice separator 32 and a turntable 311 fixed on the rice motor 31. A sliding groove 3211 is provided in the groove plate 321, and a protruding rod 312 is fixedly provided on the turntable 311 at an eccentric position. The protruding rod 312 is stuck in the sliding groove 3211.

[0067] Furthermore, a sliding plate 323 is fixed to the bottom of the rice separator 32, and the sliding plate 323 is slidably mounted on the crossbeam of the rice frame 33.

[0068] Furthermore, the rice-brown rice separator 32 is equipped with a sieve plate 322, which is inclined. The discharge port of the rice-brown rice separator 32 is set at a lower position as the brown rice outlet 324 and at a higher position as the paddy rice outlet 325.

[0069] Furthermore, the drum feed inlet 4231 is connected to the brown rice outlet 324.

[0070] In an optional embodiment, a drum air inlet 4232 and a drum air outlet 4233 are respectively provided on the side walls near both ends of the outer casing 423. The drum air inlet 4232 is located above the outer casing 423 near the drum discharge port 4211, and the drum air outlet 4233 is located below the outer casing 423 near the drum feed inlet 4231.

[0071] By introducing gas through the drum inlet 4232, the temperature and pressure inside the drum are controlled, and the exhaust gas and debris are discharged from the drum outlet 4233.

[0072] In an optional embodiment, the rice milling roller 422 is provided with a segmented spiral structure milling blade 4221, and the pitch of the milling blade 4221 is smaller the closer it is to the discharge port 4211 of the roller.

[0073] Further features include an intelligent adjustment mechanism and an optional data interaction system. The intelligent adjustment mechanism detects the gap between the rice grains in real time based on sensors and dynamically adjusts the spacing of the rice hullers 24 through the gap adjustment mechanism 213 to adapt to different rice varieties. The optional data interaction system integrates a PLC controller to automatically optimize the rice hulling parameters based on input parameters such as rice variety and rice moisture content.

[0074] Further, the sensors include pressure sensors, position sensors, etc., used to accurately detect the gap between the rice hulls and the operating status parameters of the equipment.

[0075] Furthermore, the rice hulling motor 21, the rice hulling motor 31, and the rice milling motor 41 are high-efficiency and energy-saving three-phase asynchronous motors.

[0076] Furthermore, the data interaction system also has data storage and analysis functions, which can record processing data and generate reports to facilitate production management and equipment maintenance.

[0077] Furthermore, the intelligent adjustment mechanism also includes a controller electrically connected to the angle sensor and pressure sensor. The controller adjusts the output speed of the rice milling motor 31 in real time according to the sensor data, so that the reciprocating sliding frequency of the rice milling separator 32 and the vibration frequency of the inner screen cylinder 424 form a preset phase difference, thereby reducing the resonance noise of the equipment.

[0078] Furthermore, the feed channel 22 of the rice hulling component 2 is equipped with a flow sensor and an adjustable gate. The flow sensor is electrically connected to the controller, and the controller dynamically adjusts the gate opening according to the real-time separation efficiency of the rice-hulling separator 32, so that the rice feed amount matches the rice-hulling separation capacity and avoids material accumulation.

[0079] Furthermore, the filter hole diameter of the inner sieve cylinder 424 gradually decreases from the drum inlet 4231 to the drum outlet 4211, and the filter hole edge is provided with an arc-shaped chamfer to reduce scratches on the brown rice surface.

[0080] Furthermore, the drum air inlet 4232 is connected to a temperature and humidity control device. The temperature and humidity control device introduces airflow at 30-40℃ and relative humidity of 50% to 60% into the drum according to preset parameters of the rice variety, thereby reducing the breakage rate of brown rice during the rice milling process.

[0081] Furthermore, a buffer pad is provided at the bottom of the main frame 1. When the rice-grain separation component 3 and the rice milling component 4 descend to the bottom, the buffer pad contacts the ground, and the hardness of the buffer pad gradually decreases from the center to the edge, further absorbing the vertical vibration during equipment operation.

[0082] Furthermore, the sieve plate 322 of the rice separator 32 should have a detachable structure, making it easy to replace sieve plates with different apertures according to the rice variety and size. The tilt angle of the sieve plate 322 is adjustable, which can be achieved by setting adjusting bolts at the bottom of the sieve plate 322 to adapt to different separation requirements.

[0083] Furthermore, a buffer pad, such as a rubber pad, should be installed between the cylinder of the rice milling machine 42 and the horizontal slide groove of the roller support plate 421 to reduce noise and wear during cylinder sliding. The surface of the rice milling roller 422 should be polished to reduce the coefficient of friction between the brown rice and the rice milling roller, thereby reducing damage to the brown rice surface.

[0084] Furthermore, a bearing should be installed at the rotational connection between the rotating plate 51 of the coordinating component 5 and the crossbeam of the main frame 1 to improve rotational flexibility. The airbag of the elastic component 52 should be made of aging-resistant rubber material and equipped with a pressure monitoring device, which can promptly alarm when the airbag pressure is abnormal, facilitating maintenance.

[0085] Furthermore, the intelligent regulating mechanism should possess automatic diagnostic capabilities, using sensors to monitor the operating status of each component in real time. In the event of a fault, such as motor overload or excessively high bearing temperature, it should automatically shut down and issue an alarm. Simultaneously, the intelligent regulating mechanism can connect to a remote terminal via a wireless network for remote monitoring and parameter adjustment.

[0086] Working principle: Core processing flow and drive mode: The equipment completes paddy hulling, paddy separation and rice milling through the hulling component 2, the paddy separation component 3 and the rice milling component 4 respectively. The three are driven independently by the hulling motor 21, the paddy separation motor 31 and the rice milling motor 41 respectively, and the power of each link can be precisely controlled to improve energy efficiency.

[0087] Lifting and fixing mechanisms of the rice separating component 3 and the rice milling component 4: The paddy separation component 3 and the rice milling component 4 are supported by their respective paddy frame 33 and rice milling frame 43, and the bottom lifting component 6 can control their lifting and lowering. When it descends to the bottom, it is fixed to the main frame 1 crossbeam by a pin-type locking mechanism (including pin seat and movable pin) to ensure operational stability; When rising, it detaches from the main frame 1, reducing mutual interference from vibration among components and improving processing quality; When any component rises to the top, the limiting boss 7 will lift the main frame 1 off the ground, and the bottom rollers 62 will move the entire device. After being lifted, the stability can be enhanced by another locking mechanism.

[0088] Vibration transmission and collaborative processing: The rice separator 32 is driven by the rice motor 31 through the rocker sliding mechanism (including the trough plate 321, the turntable 311, and the convex rod 312) to slide back and forth. Vibration is transmitted to the cylinder of the rice milling machine 42 by the coordinating component 5 (including rotating plate 51, elastic component 52, and adhesive plate 53), which can slide horizontally along the drum support plate 421, thereby improving the activity of brown rice and the efficiency of debris discharge. Adjusting the height of the rice milling component 4 can change the distance between the cylinder and the rotation center of the rotating plate 51, thereby adjusting the vibration transmission rate.

[0089] Airflow assistance and buffer design: The airbag (elastic component 52) ​​in the coordinating component 5 generates airflow when squeezed, which is sent to the air inlet 327 of the sieve plate of the rice separator 32 through the air supply pipe and air duct 54, helping to improve the screening rate; the spring outside the airbag can supplement the buffer force.

[0090] Intelligent adjustment function: The equipment is equipped with an intelligent adjustment mechanism that dynamically adjusts the gap of the rice huller 24 (through the gap adjustment mechanism 213), the feed rate of the feed channel 22 (through the flow sensor and the adjustable gate) and the operating parameters of each component based on data from angle sensors, pressure sensors and other sensors, so as to further optimize the processing effect.

[0091] This energy-saving integrated rice hulling and milling machine, by driving the hulling component 2, the paddy-brown separation component 3, and the rice milling component 4 with separate hulling motors 21, 31, and 41, can more efficiently control the power of each component, thereby improving energy utilization and achieving high energy efficiency. The paddy-brown separation component 3 and the rice milling component 4 are movably mounted on the main frame 1, and their lifting and lowering are controlled separately by lifting components 6. First, when the paddy-brown separation component 3 and the rice milling component 4 descend to the bottom, a locking mechanism secures the paddy-brown frame 33 and the rice milling frame 4. The frame 43 is fixed to the crossbeam of the main frame 1, which improves stability when not in use. Secondly, when the hulling component 3 and the rice milling component 4 rise, they detach from the main frame 1. At this time, the vibrations generated by the hulling component 2, the hulling component 3, and the rice milling component 4 during operation can be independent of each other, improving the rice yield and avoiding energy waste. Finally, when either the hulling component 3 or the rice milling component 4 rises to the top, the main frame 1 is lifted off the ground by the limiting boss 7, and the combined rice machine is moved by the rollers 62 at the bottom of the lifting component 6.

[0092] This energy-saving integrated rice milling machine, by setting the cylinder of the rice milling machine 42 to a horizontally sliding structure, uses the cooperating component 5 to transmit the vibration of the paddy separator 32 to the cylinder of the rice milling machine 42, thereby improving the mobility of the brown rice inside the rice milling machine 42 and the discharge rate of debris. At the same time, the cooperating component 5 can also provide a buffering force for the rice milling machine 42. Furthermore, since the rice milling component 4 is equipped with a lifting component 6, the height of the rice milling component 4 can be changed by using the lifting component 6. During the change of the height of the rice milling component 4, the distance between the cylinder of the rice milling machine 42 and the rotation center of the rotating plate 51 can also be changed, thereby adjusting the transmission rate of the vibration of the paddy separator 32 to the rice milling machine 42.

[0093] This energy-saving integrated rice hulling and milling machine uses an elastic component 52 as an airbag. The air supply pipe and air duct 54 in the rotating plate 51 discharge the air generated when the elastic component 52 is squeezed into the paddy separator 32. The airflow can improve the screening rate of the paddy separator 32. At the same time, the airbag can also improve the buffering force between the rotating plate 51, the paddy separator 32 and the rice milling machine 42.
