DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0022] The present application embodiment discloses a rice processing device and a rice processing method. Figure 1 and Figure 2 A rice processing device includes a feeding mechanism 1, a workbench 2, a polishing and dust removal mechanism 3, a driving mechanism 4, a screening mechanism 5 and a rice collecting box 6, wherein the feeding mechanism 1 is used to store raw rice and lift it to a processing position; the workbench 2 is erected on the ground; the polishing and dust removal mechanism 3 is used to polish the rice and remove dust; the driving mechanism 4 is installed on the workbench 2 and is responsible for driving the polishing and dust removal mechanism 3 to work; the screening mechanism 5 is located at the rear end of the polishing and dust removal mechanism 3 and is used to screen out impurities such as broken rice and stones; the rice collecting box 6 is used to collect processed rice.

[0023] Specifically, the feeding mechanism 1 includes a granary 11 and an elevator 12. The granary 11 stores raw rice. The elevator 12 is installed on one side of the granary 11, and the feeding end of the elevator 12 is located on the side of the discharge port of the side wall of the granary 11. Among them, the granary 11 and the elevator 12 are conventional equipment for storing and transporting raw rice in the rice processing device. The granary 11 is usually composed of a solid metal or concrete structure with good sealing and moisture resistance to ensure the storage quality of rice. In addition, the elevator 12, also known as an elevator, is mainly composed of a driving device, a conveyor belt or chain, a hopper and a frame. The working process is as follows: the raw rice enters the feeding end of the elevator 12 from the discharge port of the granary 11, and the driving device drives the hopper on the conveyor belt or chain to transport the rice upward along an inclined or vertical path, and finally delivers the rice to the entrance of the processing equipment, ready to enter the subsequent processing process. This process not only realizes the automatic transportation of rice, but also reduces the labor intensity of manual handling and improves processing efficiency. I will not go into details here.

[0024] Reference Figure 3 and Figure 4 Furthermore, the workbench 2 is erected on the ground, and the polishing and dust removal mechanism 3, the driving mechanism 4 and the screening mechanism 5 are all installed on the workbench 2, wherein the polishing and dust removal mechanism 3 includes a polishing cylinder 31 and a fan blade 32, and two vertical plates 21 are vertically fixed to the upper surface of the workbench 2, and the vertical plates 21 are arranged at intervals along the length direction of the workbench 2, and the polishing cylinder 31 is arranged in a cylindrical shape, and the axis of the polishing cylinder 31 is arranged along the length direction of the workbench 2, that is, the polishing cylinder 31 is arranged horizontally, and bearing columns 312 are integrally formed at both ends of the polishing cylinder 31, and the two bearing columns 312 are rotatably supported on the two vertical plates 21 respectively.

[0025] In addition, material valves 311 are provided at the top and bottom of the polishing cylinder 31. In the initial state, one of the material valves 311 located at the top is connected to the discharge end of the above-mentioned lift 12. When the material valve 311 is opened, the rice at the discharge end of the lift 12 can pass through the material valve 311 and enter the polishing cylinder 31. At the same time, a plurality of conical protrusions are circumferentially provided on the inner wall of the polishing cylinder 31 for better friction and polishing with the rice.

[0026] On the other hand, the fan blade 32 is rotatably supported at one end inside the polishing cylinder 31, and a dust outlet 313 is provided at the other end of the polishing cylinder 31. The dust outlet 313 is specifically provided on the supporting column 312. When the rice is polished in the polishing cylinder 31, the rice is continuously turned over and rolled, and at the same time, the fan blade 32 is controlled to rotate. The fan blade 32 generates wind force to send the dust of the rice out from the dust outlet 313 to achieve dust removal.

[0027] Furthermore, in order to improve the stability of dust removal, a filter screen 314 is provided on one side of the dust outlet 313, and the filter screen 314 is fixed to the inner wall of the polishing cylinder 31, and the filter screen 314 is used to isolate the rice to limit the rice from flying out of the dust outlet 313. At the same time, an air duct 22 is provided on the workbench 2, and the air duct 22 is connected to the dust outlet 313. A waste collection box 7 is provided under the workbench 2, and one end of the air duct 22 is located on one side of the waste collection box 7 and is connected to the waste collection box 7.

[0028] In summary, when the rice is tumbling and polishing in the polishing cylinder 31, the rotation of the fan blade 32 at one end inside the polishing cylinder 31 generates a strong wind force, which is discharged outward through the dust outlet 313 at the other end of the polishing cylinder 31. In order to improve the stability and efficiency of dust removal, a filter screen 314 fixed to the inner wall of the polishing cylinder 31 is provided on one side of the dust outlet 313. The function of the filter screen 314 is to block the rice particles and prevent them from flying out with the dust, so as to ensure that only dust and light impurities are taken out by the wind force. The air duct 22 is closely connected with the dust outlet 313, and the wind force generated by the fan blade 32 is guided to the waste collection box 7 below the workbench 2. One end of the air duct 22 is connected to the waste collection box 7. In this way, dust and light impurities are sucked into the air duct 22 under the action of wind force, and finally collected in the waste collection box 7, so that the efficient dust removal of rice during the polishing process is achieved, and the cleanliness of the working environment is ensured at the same time.

[0029] Correspondingly, during the movement of the above-mentioned polishing cylinder 31 and the fan blades 32, they are all controlled by the driving mechanism 4. Specifically, the driving mechanism 4 includes a driving motor 41, a reduction box 42 and a first transmission assembly 43. The driving motor 41 is installed on the workbench 2. The driving motor 41 is fixed to the side wall of one of the vertical plates 21. The driving motor 41 is horizontally arranged. The output shaft of the driving motor 41 penetrates into the polishing cylinder 31 and is coaxially arranged with the fan blades 32.

[0030] In addition, the reduction box 42 is installed on one of the vertical plates 21, and the reduction box 42 is located on one side of the vertical plate 21. The output shaft of the drive motor 41 is connected to the input end of the reduction box 42, wherein a first pulley transmission mechanism 8 is arranged between the output shaft of the drive motor 41 and the input end of the reduction box 42, and the two pulleys of the first pulley transmission mechanism 8 are both rotatably carried on the side wall of the vertical plate 21, one of the pulleys of the first pulley transmission mechanism 8 is coaxially fixed with the output shaft of the drive motor 41, and the other pulley of the first pulley transmission mechanism 8 is coaxially fixed with the input end of the reduction box 42.

[0031] Furthermore, the first transmission assembly 43 is used to realize the transmission between the reduction box 42 and the polishing cylinder 31. The first transmission assembly 43 includes a first transmission gear 431 and a second transmission gear 432. One of the transmission gears is coaxially connected to the output end of the reduction box 42, and the other transmission gear is coaxially sleeved on one of the supporting columns 312 on the polishing cylinder 31, and the two transmission gears are meshed with each other.

[0032] In summary, the drive motor 41 is used as a power source, and its output shaft is connected to the input end of the reduction box 42 through the first pulley transmission mechanism 8. Specifically, the first pulley transmission mechanism 8 includes two pulleys, one of which is coaxially fixed with the output shaft of the drive motor 41, and the other is coaxially fixed with the input end of the reduction box 42. The two pulleys are connected by a belt to realize the transmission of the rotation of the motor output shaft to the reduction box 42. The function of the reduction box 42 is to reduce the speed of the motor and increase the torque to meet the rotation requirements of the polishing cylinder 31 and the fan blades 32. The output end of the reduction box 42 is connected to the polishing cylinder 31 through the first transmission assembly 43. The first transmission assembly 43 consists of a first transmission gear 431 and a second transmission gear 432. The first transmission gear 431 is coaxially connected to the output end of the reduction box 42, and the second transmission gear 432 is coaxially sleeved on the bearing column 312 of the polishing cylinder 31. The two gears are meshed with each other to transmit the rotation of the reduction box 42 to the polishing cylinder 31, so that the polishing cylinder 31 and the fan blades 32 rotate synchronously to complete the polishing and dust removal process of the rice.

[0033] Furthermore, after being polished by the polishing cylinder 31 , the rice is sent out from the material valve 311 below the polishing cylinder 31 , and then enters the screening mechanism 5 for screening.

[0034] Specifically, the screening mechanism 5 includes a material trough 51, a screen 52 and a scraper 53. The material trough 51 is fixed on the vertical plate 21 and passes through the corresponding vertical plate 21. One end of the material trough 51 is located below the material valve 311 of the polishing cylinder 31. At the same time, a receiving port 23 is opened on the upper surface of the workbench 2. The receiving port 23 passes through the upper and lower surfaces of the workbench 2. The screen 52 is embedded in the receiving port 23. The other end of the material trough 51 is located on one side of the screen 52, wherein the material trough 51 is inclined downward from the end close to the material valve 311 toward the end close to the screen 52.

[0035] Furthermore, the screen 52 is located above the waste collection box 7 and on one side of the rice collection box 6 . The screen 52 is inclined, and one end of the screen 52 close to the material trough 51 is inclined downward toward the other end of the screen 52 close to the rice collection box 6 .

[0036] At the same time, the scraper 53 is slidably arranged above the screen 52 , and the scraper 53 slides along the inclined direction of the screen 52 . A second transmission assembly 9 is arranged between the scraper 53 and the reduction box 42 , and the second transmission assembly 9 is used to realize the transmission between the scraper 53 and the reduction box 42 .

[0037] Therefore, when the polishing cylinder 31 completes polishing, the lower material valve 311 is controlled to open, and the rice is sent out from the material valve 311 below the polishing cylinder 31 and falls into the material trough 51. The rice then slides from the material trough 51 into the front end of the screen 52. At this time, part of the rice will be stacked on the front end of the screen 52. Through the transmission of the second transmission assembly 9, the scraper 53 slides along the inclined direction of the screen 52 to flatten the rice with a higher stacking height. Due to the inclined setting of the screen 52 and with the assistance of the vibration brought by the operation of the drive motor 41, the screen 52 shakes accordingly, so that stones and broken rice fall from the mesh holes of the screen 52 into the waste collection box 7, and the rice that meets the specifications slides into the rice collection box 6 accordingly.

[0038] Specifically, the second transmission assembly 9 includes a second pulley transmission mechanism 91, two mutually meshing bevel gears 92, a third pulley transmission mechanism 93 and a crank-connecting rod mechanism 94. The second pulley transmission mechanism 91 is connected to the output end of the reduction gearbox 42 and one of the bevel gears 92, that is, one of the pulleys of the second pulley transmission mechanism 91 is coaxially fixed to the output end of the reduction gearbox 42, and one of the bevel gears 92 is rotatably supported on the side wall of the vertical plate 21. Correspondingly, another pulley of the second pulley transmission mechanism 91 is coaxially fixed to the bevel gear 92.

[0039] Furthermore, the turntable of the crank-connecting rod mechanism 94 is rotatably carried on the workbench 2, and the third pulley transmission mechanism 93 is connected to another bevel gear 92 and the turntable of the crank-connecting rod mechanism 94. Specifically, the other bevel gear 92 is also rotatably carried on the vertical plate 21, one of the pulleys of the third pulley transmission mechanism 93 is coaxially fixed with the other bevel gear 92, and the other pulley of the third pulley transmission mechanism 93 is coaxially fixed with the turntable of the crank-connecting rod mechanism 94, and the scraper 53 is hinged to the connecting rod of the crank-connecting rod mechanism 94.

[0040] Therefore, when the reduction box 42 rotates under the control of the drive motor 41, under the action of the second pulley transmission mechanism 91, the two bevel gears 92 rotate synchronously, and then through the transmission of the third pulley transmission mechanism 93, the turntable of the crank-connecting rod mechanism 94 rotates, and the connecting rod of the crank-connecting rod mechanism 94 swings, thereby driving the scraper 53 to reciprocate.

[0041] Furthermore, a guide groove is formed on the inner wall of the accommodating opening 23 along the inclination direction of the screen 52, and a guide block 531 is fixed to the side wall of the scraper 53. The guide block 531 is slidably arranged in the guide groove along the length direction of the screen 52, thereby limiting the movement trajectory of the scraper 53 and further improving the movement stability of the scraper 53.

[0042] On the other hand, the top cover of the workbench 2 is provided with a dust cover, and the dust cover is arranged on the outside of the screening mechanism 5, so as to reduce the occurrence of dust adhering to the surface of the rice.

[0043] Furthermore, a feeding hopper 61 is provided on the top of the rice collecting box 6, and the feeding hopper 61 is communicated with the inside of the rice collecting box 6, and an observation window 62 is provided on the side wall of the rice collecting box 6. The feeding hopper 61 is convenient for feeding rice, and the observation window 62 is made of an acrylic plate with a certain degree of transparency, so that the operator can observe the collection situation inside the rice collecting box 6.

[0044] The embodiment of the present application also discloses a rice processing method, which is performed using the above-mentioned rice processing device and includes the following steps.

[0045] S1: The raw rice enters the lifting machine 12 from the discharge port of the granary 11, and the rice is sent to the entrance of the processing equipment through the lifting machine 12, ready to enter the subsequent processing process; S2: The rice enters the polishing cylinder 31, and is polished by the rotation of the polishing cylinder 31 and the action of the internal fan blades 32, while the dust and light impurities generated during the processing are discharged through the dust outlet 313 of the polishing cylinder 31; S3: The polished and dust-removed rice enters the screening mechanism 5, and the impurities such as broken rice and stones in the rice are screened out through the screening effect of the screen 52 to ensure the purity of the rice; S4: The clean rice after sieving finally falls into the rice collecting box 6, completing the processing process. The collecting box is used to store and collect the processed rice for subsequent packaging and transportation. S5: The entire processing process is controlled by the driving mechanism 4 to ensure the normal operation of the polishing cylinder 31 and the fan blades 32. At the same time, the processing effect and efficiency are guaranteed by controlling the operating parameters of the equipment, such as rotation speed, time, etc.

[0046] Therefore, the rice processing method of the embodiment of the present application realizes efficient and clean processing of rice from raw materials to finished products by adopting a specific rice processing device. First, the raw rice is sent to the processing equipment via the lifting machine 12, and then the surface impurities are effectively removed by rotation and the action of the internal fan blades 32 in the polishing cylinder 31, and the dust and light impurities are discharged by the dust outlet 313 to ensure that the surface of the rice is smooth. Then, the rice enters the screening mechanism 5, and the impurities such as broken rice and stones are screened and removed by the screen 52, further improving the purity of the rice. Finally, the clean rice falls into the collection box, completing the entire processing flow, which is convenient for subsequent packaging and transportation. The entire processing process is accurately controlled by the driving mechanism 4 to ensure the stable operation of the polishing cylinder 31 and the fan blades 32. At the same time, by adjusting the equipment operating parameters, such as the rotation speed and time, the processing effect and efficiency are guaranteed, the automation and standardization of rice processing are realized, and the processing quality and production efficiency of rice are significantly improved.

[0047] The implementation principle of a rice processing device in the embodiment of the present application is: The fan blades 32 and the polishing cylinder 31 are driven by the driving motor 41 to rotate synchronously, so as to realize efficient polishing and dust removal of rice. Specifically, the output shaft of the driving motor 41 is connected to the reduction box 42 through the first pulley transmission mechanism 8. After the reduction box 42 reduces the rotation speed and increases the torque, the power is transmitted to the polishing cylinder 31 through the first transmission assembly 43, so that the fan blades 32 in the polishing cylinder 31 rotate. In the polishing cylinder 31, while the rice is tumbling and polishing, the wind force generated by the fan blades 32 discharges the dust from the dust outlet 313. The filter screen 314 on one side of the dust outlet 313 prevents the rice from flying out, and the air duct 22 guides the dust to the waste collection box 7 to realize dust removal. Then, the stones and broken rice are screened out by the screening mechanism 5. The whole process ensures the high efficiency and cleanliness of rice processing through precise transmission and control.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
