Description

Technical Field

[0001] The utility model relates to the technical field of rice screening, in particular to a rice grading and screening optimization device. Background Art

[0002] The rice grading, screening and optimization device is a device specially used for grading, screening and optimizing rice. Its working principle is to grade rice according to size, shape and quality by vibration and screening, so as to separate high-quality rice from inferior rice. The device is usually composed of a feeding system, a screening system, a vibration system and a discharging system. The feeding system sends rice into the screening system through a conveyor belt or a bucket elevator. The screening system uses sieves with different mesh sizes to grade and screen the rice. The vibration system vibrates the rice through a vibrator to accelerate the screening process. Finally, rice of different grades is separated and placed through the discharging system.

[0003] At present, the existing new type of rice grader (such as patent number: CN211756818U) discloses a new type of rice grader, including a material dividing inclined bucket, an inclined bucket bracket, a material dividing inclined plate, a grading bed, a grading baffle, a grading screen plate, a grading bed upper bracket, a grading bed lower bracket, and a bracket connecting spring. The material dividing inclined bucket is fixed to the top of the inclined bucket bracket, and the front side of the material dividing inclined bucket is provided with a material dividing opening. The grading bed is arranged on the front side of the material dividing inclined bucket, and the material dividing inclined plate is connected to the bottom side of the material dividing opening and one end of the grading bed. The utility model is beneficial to optimize the setting of the rice grading equipment, change the traditional setting of manual rice screening, and improve it into an advanced mechanical screening setting. The equipment adopts different grading screen plates for screening, and can screen rice of different sizes in detail. In addition, the bottom of the equipment is equipped with a vibration device, which can well guarantee the effect of rice screening. The cast iron material used for the whole equipment is strong and durable, cheap, and suitable for popularization and use.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] Rice screening is graded through a sieve. When the staff cannot control the feeding speed of rice and put in too much rice, the sieve holes on the sieve cannot handle so much material in time, which may cause the sieve holes on the sieve to be blocked, making the rice grading inaccurate and affecting the product quality.

[0027] The embodiment of the present application provides a rice grading and screening optimization device, which effectively solves the problem that rice screening is graded through a sieve. When the staff member over-puts rice due to the inability to control the rice feeding speed, the sieve holes on the sieve cannot handle so much material in time, which may cause the sieve holes on the sieve to be blocked, resulting in inaccurate rice grading and affecting product quality. When the feeding device is needed to pour rice into the device body, the motor is started, and the motor drives the connecting column and the rotating bevel gear to rotate. At this time, the two meshing bevel gears meshing with the rotating bevel gear will drive the threaded rod to rotate. Since the two moving blocks 2 do not rotate, the two moving blocks 2 will drive the moving plates to rotate in opposite directions when the two threaded rods rotate. When the two moving plates move, the two moving blocks 1 will move along the long rod. At this time, the rice on the feeding device will be fed from the opening between the two moving plates. When the moving plates are moved to a suitable position, the motor is turned off. By controlling the distance between the moving plates, the feeding rate of the control device body is achieved, thereby avoiding the problem of excessive feeding of rice by the staff member causing clogging of the sieve holes, making the rice screening process more accurate and the product quality unaffected.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that when rice is screened and graded through a sieve, when the staff cannot control the feeding speed of the rice and over-inputs the rice, the sieve holes on the sieve cannot handle so much material in time, which may cause the sieve holes on the sieve to be blocked, making the rice grading inaccurate and affecting the product quality. The overall idea is as follows:

When the unloading device 2 is needed to pour rice into the device main body 1, the motor 3 is started, and the motor 3 drives the connecting column 16 and the rotating bevel gear 17 to rotate. At this time, the two meshing bevel gears 12 meshed with the rotating bevel gear 17 will drive the threaded rod 8 to rotate. Since the two moving blocks 2 10 do not rotate, the two moving blocks 2 10 will drive the moving plate 5 to rotate in the opposite direction when the two threaded rods 8 rotate. When the two moving plates 5 move, the two moving blocks 1 7 will move along the long rod 6. At this time, the rice on the unloading device 2 will be unloaded from the opening between the two moving plates 5.

[0031] A fixing plate 11 is provided at one end of the two meshing bevel gears 12 facing away from the rotating bevel gear 17. The two fixing plates 11 are fixedly connected to the inner wall of the fixing frame 4. A hole 14 is penetrated through the front surface of the two fixing plates 11. The two threaded rods 8 are rotatably connected to the fixing plates 11 through the hole 14 until the movable plate 5 is moved to a suitable position, and then the motor 3 is turned off. By controlling the distance between the movable plates 5, the rate of material discharge of the control device body 1 is achieved, thereby avoiding the problem of excessive rice input by the staff causing blockage of the sieve holes, making the rice screening process more accurate and the product quality unaffected.

[0032] The two threaded rods 8 are fixedly connected to the corresponding meshing bevel gears 12 on one side facing the rotating bevel gear 17, and the two threaded rods 8 are rotatably connected to the inner wall of the fixed frame 4 on one side facing away from the rotating bevel gear 17. The two moving blocks 17 are fixedly connected to the right surfaces of the two moving plates 5. The front surfaces of the two moving blocks 17 are penetrated with holes 13. The two moving blocks 17 are movably connected to the long rod 6 through the holes 13. A connecting column 16 is provided inside the fixed frame 4. The lower surface of the connecting column 16 is rotatably connected to the inner wall of the fixed frame 4. The two moving blocks 10 are fixedly connected to the left surfaces of the two moving plates 5. The two movable blocks 10 are fixedly connected, and both movable blocks 10 are movably connected with the fixed frame 4. The front surfaces of the two movable blocks 10 are penetrated with threaded grooves 19. The two movable blocks 10 are threadedly connected with the corresponding threaded rods 8 through the threaded grooves 19. When the unloading device 2 needs to be closed, the control motor 3 outputs in reverse, so that the two movable blocks 1 7 and the two movable blocks 10 drive the two movable plates 5 to approach each other. When the two movable plates 5 are close to a certain distance, the two movable blocks 10 will resist the two fixed plates 11, avoiding the problem of collision and damage of the two movable plates 5 caused by the two movable plates 5 being fixed and moved close to each other.

[0033] Working principle: when the unloading device 2 needs to pour rice into the device body 1, the motor 3 is started, and the motor 3 drives the connecting column 16 and the rotating bevel gear 17 to rotate. At this time, the two meshing bevel gears 12 meshing with the rotating bevel gear 17 will drive the threaded rod 8 to rotate. Since the two moving blocks 10 do not rotate, the two moving blocks 10 will drive the moving plate 5 to rotate in the opposite direction when the two threaded rods 8 rotate. When the two moving plates 5 move, the two moving blocks 17 will move along the long rod 6. At this time, the rice on the unloading device 2 will be unloaded from the opening between the two moving plates 5 until the moving plates 5 are moved. When the feeding device 2 moves to a suitable position, the motor 3 is turned off, and the feeding rate of the control device body 1 is achieved by controlling the distance between the moving plates 5, thereby avoiding the problem of excessive rice input by the staff causing blockage of the sieve holes, making the rice screening process more accurate and the product quality not affected. When it is necessary to close the feeding device 2, the motor 3 is controlled to output in the reverse direction, so that the two moving blocks 1 7 and the two moving blocks 2 10 drive the two moving plates 5 to approach each other. When the two moving plates 5 are close to a certain distance, the two moving blocks 2 10 will resist the two fixed plates 2 11, thereby avoiding the problem of the two moving plates 5 being damaged by collision due to the fixed and close movement.
