Description

Technical Field

[0001] The utility model belongs to the technical field of rice processing, in particular to a polishing device used for rice processing. Background Art

[0002] During the rice processing process, the rice needs to be polished in order to improve its gloss and taste.

[0003] During the polishing process, the rice needs to be driven by the polishing roller. During the movement, the rice grains and the screen on the inner wall of the polishing chamber will move relative to each other. During the movement, the burrs and bran powder on the surface of the rice are removed, thereby achieving the effect of polishing the dust-introducing rice. However, the hardness of the rice grains varies according to different rice varieties. During the polishing process of the existing polishing equipment, since the time required for polishing the rice from the beginning to the completion is the same, when polishing some softer rice, it is easy to produce too much broken rice due to the long polishing time, which affects the quality of the rice.

The bottom of the moving block 7 is rotatably connected to a connecting rod 8, and the bottom end of the connecting rod 8 is rotatably connected to the top of the polishing cylinder 4 away from the support frame 2. Since the polishing cylinder 4 as a whole can only rotate around the top of the support frame 2, in the process of the threaded rod 6 driving the moving block 7 to move, the moving plate can drive the other end of the polishing cylinder 4 to move upward or downward through the connecting rod 8, thereby changing the inclination of the polishing cylinder 4. After the inclination of the polishing cylinder 4 changes, due to the influence of gravity, the rice will pass through the inside of the polishing cylinder 4 at a faster or slower speed, thereby adjusting the polishing time.

[0023] Among them, a rice outlet 9 is provided at the bottom of the polishing cylinder 4 away from the support frame 2. After the rice moves to the rice outlet 9 inside the polishing cylinder 4, it will be discharged from the rice outlet 9. A first rice receiving hopper 10 is penetrated on the inner wall of the chassis 1 on the side away from the support frame 2 and below the rice outlet 9. After the rice discharged from the rice outlet 9 falls on the first rice receiving hopper 10, it will be discharged from the first rice receiving hopper 10. A second rice receiving hopper 11 is provided at the top of the polishing cylinder 4 away from the rice outlet 9. A rice inlet hopper 12 is penetrated on the top of the chassis 1 just above the second rice receiving hopper 11, and the bottom of the rice inlet hopper 12 penetrates into the second rice receiving hopper 11. The rice enters the chassis 1 from the rice inlet hopper 12 and falls into the second rice receiving hopper 11, and then enters the polishing cylinder 4 from the second rice receiving hopper 11.

[0024] Among them, the surface of the polishing roller 5 is provided with an auger blade 13 and a polishing flap 14, and the auger blade 13 is arranged on the surface of the polishing roller 5 close to one end of the support frame 2, the auger blade 13 is used to push the rice entering the polishing cylinder 4 from the second rice receiving bucket 11 toward the rice outlet 9, there are multiple polishing flaps 14, and they are evenly arranged on the surface of the polishing roller 5. In the process of rice moving from one end of the auger blade 13 toward the rice outlet 9, the polishing flap 14 is used to drive the rice to rotate, thereby polishing the rice.

[0025] The polishing cylinder 4 is provided with a screen 15 between the second rice receiving hopper 11 and the rice outlet 9 , and the bran powder and burrs produced by polishing can pass through the screen 15 and fall into the bottom of the chassis 1 .

[0026] The bottom of the chassis 1 is funnel-shaped, and a powder outlet 16 is provided at the bottom of the funnel. Under the action of the bottom of the funnel-shaped chassis 1, bran powder and burrs slide into the powder outlet 16 and are discharged.

[0027] A fixing frame 17 is further provided at the bottom of the chassis 1 , and the fixing frame 17 is used to support and fix the chassis 1 .

[0028] Among them, a first motor 18 is fixedly installed on one side of the chassis 1, and the output end of the first motor 18 is connected to the threaded rod 6 through a coupling transmission. The first motor 18 can drive the threaded rod 6 chassis 1 to rotate. A transmission shaft is provided at the end of the polishing roller 5 away from the rice outlet 9.

[0029] Specific working principle:

[0030] Before using the utility model, first connect the utility model to an external power supply and a control panel, and control the operation of the utility model through the external control panel. When polishing rice, the utility model first starts the second motor 19 of the utility model, and then pours the rice into the rice inlet hopper 12. The rice entering the rice inlet hopper 12 then falls into the second rice receiving hopper 11, and then falls into the polishing cylinder 4 from the second rice receiving hopper 11. Under the drive of the first motor 18, the polishing roller 5 rotates inside the polishing cylinder 4. During the rotation of the polishing cylinder 4, the auger blades 13 on the surface of the polishing cylinder 4 push the rice entering from the second rice receiving hopper 11 toward the rice outlet hopper, so that it enters between the polishing flaps 14. The polishing roller 5 drives the polishing flaps 14 to rotate so that the rice continuously rotates in the polishing cylinder 4. During the movement, the surface of the rice is polished, and the rice powder and the like produced by the polishing leave the polishing cylinder 4 from the screen 15. Finally, the polished rice falls into the first rice receiving bucket 10 from the rice outlet 9 and is discharged. Before polishing the rice, according to the variety of rice, the first motor 18 in the utility model can be started, and the first motor 18 drives the threaded rod 6 to rotate, and the threaded rod 6 drives the moving block 7 meshed with it to rotate, so that the moving block 7 pulls the end of the polishing cylinder 4 upward or downward through the connecting rod 8, thereby changing the inclination of the polishing cylinder 4. Due to the change in inclination, under the influence of gravity, the time that the rice passes through the polishing cylinder 4 will also change accordingly, so that the time for polishing the rice can be adjusted, thereby reducing the amount of broken rice that occurs when polishing some softer rice.
