One end of the rotating rod is connected to the edge of the rotating disk, and the other end is connected to a fixing plate fixed on the stable frame by means of a rotating shaft. Therefore, the screening plate is driven by the rotating disk to vibrate, so as to achieve the purpose of bran removal.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, the present invention provides a rice processing bran removal device, comprising a bran removal device 1, wherein the bran removal device 1 comprises a vibration mechanism 2 and a material discharge mechanism 3, wherein the vibration mechanism 2 is located above the material discharge mechanism 3;

[0035] The vibration mechanism 2 includes a stabilizing frame 21, a fixing plate 22, a rotating rod 23, a rotating disk 24 and a driving motor 25. The bottom surface of the stabilizing frame 21 is hinged with a screening plate 26 through a hinge. The fixing plate 22 is fixedly connected to the top surface of one end of the stabilizing frame 21. One end of the rotating rod 23 is rotatably connected to the top of the fixing plate 22, and the other end of the rotating rod 23 is rotatably connected to the top of the rotating disk 24. The bottom surface of the rotating disk 24 is spline-connected to the output end of the driving motor 25.

[0036] The unloading mechanism 3 includes a hydraulic rod 31, an inclined plate 32, a reset member 33, a slide rail 34, a sliding cover 35 and a discharge plate 36. The hydraulic rod 31 is located above the inclined plate 32, the reset member 33 is fixedly installed on one side of the inclined plate 32, the slide rail 34 is slidably connected to the inclined plate 32, and the sliding cover 35 is slidably connected to the top surface of the discharge plate 36.

[0037] The above scheme is adopted: the telescopic spring 331 is sleeved on the outside of the elastic column 332. When the inclined plate 32 is tilted due to the weight of rice, the telescopic spring 331 is compressed and the elastic column 332 is under pressure. When the rice flow rate decreases or stops, the elastic force of the telescopic spring 331 and the supporting force of the elastic column 332 restore the inclined plate 32 to the initial position or close to the initial position, thereby ensuring the stability and continuity of the unloading process. After the rice screening is completed, through the setting of the unloading mechanism 3, the hydraulic rod 31 starts to operate and drives the screening plate 26 to perform an arc movement. The screening plate 26 contacts the inclined plate 32 and applies pressure to it, so that The inclined plate 32 moves toward the inner wall of the processing bin 5. When the inclined plate 32 moves, the connecting rod 37 at its bottom will slide accordingly inside the slide rail 34, thereby driving the sliding cover 35 to move on the discharge plate 36, thereby opening the discharge plate 36. The screening plate 26 is placed on the discharge plate 36, and the rice on the screening plate 26 flows into the discharge plate 36 to complete the unloading operation. The screening plate 26 is placed on the discharge plate 36 to allow the rice to flow into the discharge plate 36, thereby avoiding the breakage of the rice caused by falling directly from a higher position. The rice can maintain the integrity of the particles during a relatively smooth transition process.

[0038] like Figures 2 to 6 As shown, the bran removal equipment 1 also includes a feed bin 4 and a processing bin 5, and the feed bin 4 is connected to the top of the processing bin 5, a cleaning piece 6 is fixedly installed on the top of the feed bin 4, a feeding hopper 7 is fixedly installed on one side of the top of the feed bin 4, the cleaning piece 6 includes a blower fixedly connected to one side of the top of the feed bin 4, the output end of the blower is connected to a conveying pipe 61, the conveying pipe 61 passes through the processing bin 5 and is connected to an exhaust pipe 62, a bracket is fixedly installed on the conveying pipe 61, and the bottom surface of the bracket is connected to one side of the feed bin 4, sliding grooves 41 are provided on both sides of the bottom of the feed bin 4, the sliding grooves 41 are slidably connected to the stabilizing frame 21, the top surface of the fixing plate 22 is fixedly connected with a rotating shaft, the fixing plate 22 is rotatably connected to the rotating rod 23 through the rotating shaft, the other end of the rotating rod 23 is rotatably connected to the edge of the rotating disk 24, and the driving motor 25 is fixedly installed on the outer wall of the feed bin 4 close to the cleaning piece 6.

[0039] The above scheme is adopted: through the setting of the vibration mechanism 2, the rice raw material first enters the feeding bin 4 through the feed hopper 7, and then falls into the screening plate 26 of the vibration mechanism 2 above the processing bin 5 through the bottom of the feeding bin 4. At this time, the driving motor 25 is started, and the motor drives the rotating disk 24 to rotate. The rotating rod 23 is connected to the edge of the rotating disk 24 at one end, and the other end is connected to the fixing plate 22 fixed on the stable frame 21 by means of a rotating shaft, so that the screening plate 26 is driven by the rotating disk 24 to vibrate, thereby achieving the purpose of removing bran. During the vibration process of the screening plate 26, the rice keeps jumping and rolling, so that smaller bran scraps have more opportunities to fall through the sieve holes. Compared with some static screening methods, the efficiency of bran removal is greatly improved. This dynamic screening can quickly process a large amount of rice and meet the needs of large-scale rice processing and production. The design of the entire vibration mechanism 2 is reasonable, and the connection between the various components is tight and stable. The drive motor 25 transmits power to the screening plate 26 through the rotating disk 24, the rotating rod 23 and the fixed plate 22. This transmission method can ensure that the screening plate 26 vibrates continuously and stably. The stabilizing frame 21 provides a solid support for the screening plate 26, so that the equipment can maintain good performance during long-term operation and reduce equipment failures and maintenance costs caused by unstable vibration.

[0040] like Figures 3 to 6 As shown, a rotating block 261 is installed at the bottom of the screening plate 26 near one end of the unloading mechanism 3, the bottom of the rotating block 261 is rotatably connected to the end of the hydraulic rod 31 near the unloading mechanism 3, the end of the hydraulic rod 31 near the cleaning member 6 is rotatably connected to the inner wall of the processing bin 5, the reset member 33 includes a telescopic spring 331 and an elastic column 332, the telescopic spring 331 is sleeved on the outer wall of the elastic column 332, one end of the telescopic spring 331 is fixedly connected to one side of the inside of the processing bin 5, one end of the elastic column 332 is connected to the surface of one side of the inclined plate 32, and the other end of the elastic column 332 is connected to the inner wall of the processing bin 5, one side of the slide rail 34 is also connected to one side of the inside of the processing bin 5, and the slide rail 34 is located below the reset member 33, the bottom surface of the inclined plate 32 is fixedly connected to a connecting rod 37, the bottom surface of the connecting rod 37 is fixedly connected to the top surface of the sliding cover 35, and the bottom of the discharge plate 36 is inclined.

[0041] With the above solution, the jumping and rolling action of the rice on the screening plate 26 enables each part of the rice to fully contact the screening plate 26, thereby ensuring that the bran can be separated from each corner of the rice. Rather than just the bran on the surface being removed, this helps to improve the thoroughness of bran removal, so that the screened rice has a higher purity and better meets the quality requirements of subsequent processing or sales. The rotating rod 23: connects the fixed plate 22 and the rotating disk 24, and converts the circular motion of the rotating disk 24 into the up and down vibration of the screening plate 26, so that the rice on the screening plate 26 can be effectively separated from the bran during the vibration. The rotating disk 24 is splined to the output end of the driving motor 25, and moves in a circular motion under the drive of the driving motor 25, driving the rotating rod 23 to move, thereby providing a vibration source for the screening plate 26. The driving motor 25 provides power for the entire vibration mechanism 2. By controlling its rotation speed and direction, the vibration frequency and amplitude of the screening plate 26 can be adjusted to meet different bran removal requirements. The screening plate 26 has sieve holes on its surface, which is a key component for separating rice from bran. When the rice vibrates on its surface, the bran can fall through the sieve holes, while the rice remains on the screening plate 26 and continues to enter the next step of processing.

[0042] The working principle and use process of the present invention are as follows: the rice raw material first enters the feeding bin 4 through the feeding hopper 7, and then falls onto the screening plate 26 of the vibration mechanism 2 above the processing bin 5 through the bottom of the feeding bin 4. At this time, the driving motor 25 is started, and the motor drives the rotating disk 24 to rotate. The rotating rod 23 is connected to the edge of the rotating disk 24 at one end, and is connected to the fixing plate 22 fixed on the stabilizing frame 21 at the other end by means of a rotating shaft, so that the screening plate 26 is driven by the rotating disk 24 to vibrate. During this vibration process, the rice continues to jump and roll on the screening plate 26. During this period, smaller bran scraps fall through the sieve holes of the screening plate 26, and finally the purpose of bran removal is achieved;

[0043] After the rice is screened, the hydraulic rod 31 is started, and the hydraulic rod 31 starts to move, driving the screening plate 26 to make an arc movement. When the screening plate 26 moves, it contacts the inclined plate 32 and squeezes the inclined plate 32 to move toward the inner wall of the processing bin 5. While moving, the inclined plate 32 drives the connecting rod 37 to slide inside the slide rail 34, and then drives the sliding cover 35 to move on the discharge plate 36, so as to open the discharge plate 36. At the same time, the reset member 33 (telescopic spring 331 and elastic column 332) on one side of the inclined plate 32 will buffer and reset the change of the inclined plate 32, so as to ensure the stability of the inclined plate 32 and normal unloading. At this time, the screening plate 26 is placed on the discharge plate 36, so that the rice on the screening plate 26 flows into the discharge plate 36 to realize unloading.

[0044] After unloading is completed, the hydraulic rod 31 extends outward. At this time, the screening plate 26 gradually moves away from the sliding cover 35, and the sliding cover 35 slowly closes, so that the telescopic spring 331 and the elastic column 332 begin to drive the inclined plate 32 to reset. While the hydraulic rod 31 is moving, the screening plate 26 will contact and squeeze the inclined plate 32. When the screening plate 26 is separated from the inclined plate 32, the reset member 33 will drive the sliding cover 35 to reset, so that the discharge plate 36 is in a closed state. At this time, the cleaning member 6 starts to work, and the blower generates airflow. The airflow passes through the conveying pipe 61 to the exhaust pipe 62, forming an air path in the conveying bin 4, and conveys the bran in the processing bin 5 to the external device.
