Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a rice processing polishing machine. Background Technology

[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, separation, conditioning, milling, polishing, color sorting, and packaging. In order to make the rice surface smooth and shiny, and at the same time remove a small amount of bran powder and other impurities from the surface to obtain fine rice, it is necessary to use a rice processing polishing machine to polish the rice after milling.

[0003] In existing rice processing polishing machines, workers typically add rice into the polishing box through the feed inlet. As the rice falls, it rubs against the polishing rollers inside the machine to polish it. After polishing, a vibrating motor is used to vibrate the filter screen to separate the impurities.

[0004] Existing rice processing polishing machines have the following problems: a single vibrating motor vibrates the filter screen, which cannot provide sufficient vibration amplitude, so that the rice cannot bounce and loosen fully, making it difficult for impurities to pass through the filter screen holes and reducing the efficiency of the polishing work. To address this, we propose a rice processing polishing machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a rice processing and polishing machine. By shaking the filter screen through the screening mechanism, sufficient vibration amplitude can be provided to achieve full jumping and loosening of the rice, so that impurities can quickly pass through the filter screen holes, thereby improving the efficiency of the polishing work and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice processing and polishing machine, comprising a polishing box and a sieving mechanism;

[0007] Screening mechanism: It includes a rotating rod, a connecting rod, a rotating shaft, a transmission rod, a chute, fixed columns, a mounting frame, springs, a U-shaped seat, and a filter screen. The rotating rod is rotatably connected to the left side wall of the polishing box. A connecting rod is provided at the left end of the rotating rod. The end of the connecting rod away from the rotating rod is rotatably connected to the rotating shaft. A transmission rod is fixedly sleeved on the left end of the outer surface of the rotating shaft. The left and right sides of the interior of the polishing box are provided with chute. Fixed columns are provided inside the chute. A mounting frame is slidably connected between two fixed columns. Springs are movably sleeved on the outer surface of each fixed column. The springs are located between the lower surface of the mounting frame and the bottom wall of the chute. A U-shaped seat is provided on the lower surface of the mounting frame. The end of the transmission rod away from the rotating shaft is rotatably connected to the inside of the U-shaped seat. A filter screen is provided inside the mounting frame. By shaking the filter screen through the screening mechanism, sufficient vibration amplitude can be provided to achieve full jumping and loosening of the rice, allowing impurities to quickly pass through the filter screen holes, thus improving the efficiency of the polishing work.

[0008] Furthermore, it also includes a microcontroller, which is fixedly connected to the front side of the polishing box. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0009] Furthermore, a motor is provided on the right side of the polishing box. The left end of the output shaft of the motor is fixedly connected to the right end of the rotating rod, and the input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0010] Furthermore, the polishing box is internally connected to a rotating shaft, and a polishing roller is fixedly sleeved on the outer surface of the rotating shaft. A second motor is provided on the right side of the polishing box. The left end of the output shaft of the second motor is fixedly connected to the right end of the rotating shaft, and the input end of the second motor is electrically connected to the output end of the microcontroller, which facilitates the polishing of rice.

[0011] Furthermore, the polishing box is equipped with guide plates on both the front and rear sides. The guide plates are located on the front and rear sides of the polishing roller, and the upper surface of the guide plates is inclined to facilitate the flow of rice.

[0012] Furthermore, a protective door is hinged to the opening on the front side of the polishing box, and a glass observation window is provided on the front side of the protective door to facilitate observation of the impurity screening process.

[0013] Furthermore, a waste bin is slidably connected to the opening on the right side of the polishing box, and a handle is provided on the right side of the waste bin to facilitate the collection of impurities generated during polishing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This rice processing and polishing machine has the following advantages:

[0015] The rotation of the rotating rod causes the connecting rod to rotate around the rotating rod as the center. Under the constraint of the sliding groove, the connecting rod causes the rotating shaft to rotate around the rotating rod while rotating on its own axis. The rotation of the rotating shaft drives the U-shaped seat to move up and down through the transmission rod, causing the mounting frame to move up and down along the fixed column, thereby causing the filter screen to move up and down. This can provide sufficient vibration amplitude to achieve full jumping and loosening of the rice, allowing impurities to pass through the filter screen holes quickly and improving the efficiency of the polishing work.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a rice processing polishing machine, including a polishing box 1 and a screening mechanism 3, and also includes a microcontroller 2. The microcontroller 2 is fixedly connected to the front side of the polishing box 1, and its input end is electrically connected to an external power source. A rotating shaft 5 is rotatably connected inside the polishing box 1, and a polishing roller 6 is fixedly sleeved on the outer surface of the rotating shaft 5. A second motor 7 is provided on the right side of the polishing box 1, and the left end of the output shaft of the second motor 7 is fixedly connected to the right end of the rotating shaft 5. The input end of the second motor 7 is electrically connected to the output end of the microcontroller 2. Guide plates 8 are provided on both the front and rear sides of the interior of the polishing box 1. The guide plates 8 are located on the front and rear sides of the polishing roller 6, and their upper surfaces are inclined. The opening on the front side of the polishing box 1... A protective door 9 is hinged to a certain point. A glass observation window 10 is provided on the front side of the protective door 9. A waste bin 11 is slidably connected to the opening on the right side of the polishing box 1. A handle 12 is provided on the right side of the waste bin 11. The staff puts rice into the polishing box 1 through the feed port, and then operates the microcontroller 2 to turn on the motor 7. The output shaft of the motor 7 drives the polishing roller 6 to rotate through the rotating shaft 5. As the rice falls, it is guided by the guide plate 8 and rubs against the polishing roller 6 inside the polishing box 1 to polish it. Impurities fall into the waste bin 11. Then the staff can open the protective door 9 to collect the rice. After working for a period of time, the staff can pull out the waste bin 11 through the handle 12 to clean the impurities.

[0022] Screening mechanism 3 includes a rotating rod 301, a connecting rod 302, a rotating shaft 303, a transmission rod 304, a chute 305, a fixed column 306, a mounting frame 307, a spring 308, a U-shaped seat 309, and a filter screen 310. The rotating rod 301 is rotatably connected to the left side wall of the polishing box 1. The left end of the rotating rod 301 is provided with a connecting rod 302. The end of the connecting rod 302 away from the rotating rod 301 is rotatably connected to the rotating shaft 303. The transmission rod 304 is fixedly sleeved on the left end of the outer surface of the rotating shaft 303. 4. The polishing box 1 has sliding grooves 305 on both the left and right sides inside. Each sliding groove 305 has a fixing post 306 inside. A mounting frame 307 is slidably connected between two fixing posts 306. Springs 308 are movably fitted onto the outer surface of each fixing post 306. The springs 308 are located between the lower surface of the mounting frame 307 and the bottom wall of the sliding groove 305. A U-shaped seat 309 is provided on the lower surface of the mounting frame 307. The end of the transmission rod 304 away from the rotating shaft 303 is rotatably connected to the U-shaped seat 309. Inside, the mounting frame 307 houses a filter screen 310. A motor 4 is located on the right side of the polishing box 1. The left end of the output shaft of motor 4 is fixedly connected to the right end of the rotating rod 301. The input end of motor 4 is electrically connected to the output end of the microcontroller 2. Polished rice falls onto the filter screen 310. Simultaneously, motor 4 is turned on, and its output shaft drives the rotating rod 301 to rotate. The rotation of the rotating rod 301 causes the connecting rod 302 to rotate around the rotating rod 301, confined by the slide groove 305. The connecting rod 302 causes the rotating shaft 303 to rotate around the rotating rod 301 while rotating on its own axis. The rotation of the rotating shaft 303 drives the U-shaped seat 309 to move up and down through the transmission rod 304, causing the mounting frame 307 to move up and down along the fixed column 306 inside the slide groove 305, which in turn causes the filter screen 310 to move up and down. This provides sufficient vibration amplitude to fully agitate and loosen the rice, allowing impurities to quickly pass through the filter holes on the filter screen 310, thus improving the efficiency of the polishing process.

[0023] The working principle of the rice processing and polishing machine provided by this utility model is as follows: The operator adds rice into the polishing box 1 through the feed inlet, then controls the microcontroller 2 to turn on motor 7. The output shaft of motor 7 drives the polishing roller 6 to rotate via the rotating shaft 5. During the falling process, the rice is guided by the guide plate 8 and rubs against the polishing roller 6 inside the polishing box 1 for polishing. The polished rice falls onto the filter screen 310. Simultaneously, motor 4 is turned on, and the output shaft of motor 4 drives the rotating rod 301 to rotate. The rotation of the rotating rod 301 causes the connecting rod 302 to rotate around the rotating rod 301. Under the constraint of the sliding groove 305, the connecting rod 302... The rotating shaft 303 rotates around the rotating rod 301 while rotating on its own axis. The rotation of the rotating shaft 303 drives the U-shaped seat 309 to move up and down through the transmission rod 304, causing the mounting frame 307 to move up and down along the fixed column 306 inside the slide groove 305. This causes the filter screen 310 to move up and down, providing sufficient vibration amplitude to achieve full jumping and loosening of the rice, allowing impurities to quickly pass through the filter holes on the filter screen 310, improving the efficiency of the polishing work. The impurities fall into the waste bin 11, and then the staff can open the protective door 9 to collect the rice. After working for a period of time, the staff can pull out the waste bin 11 through the handle 12 to clean the impurities.
