[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.
[0021] like Figure 1-Figure 3As shown, the present embodiment provides a rice polishing machine for rice processing, comprising a polishing cylinder 1, a transmission box 4 being installed at the top of the polishing cylinder 1, a motor 15 being arranged in the transmission box 4, a driving wheel 16 being fixed on the output shaft of the motor 15, a driven wheel 18 being arranged on one side of the driving wheel 16, a lifting cylinder 8 being provided on one side of the polishing cylinder 1, a spiral shaft 12 being installed in the lifting cylinder 8, a material guide pipe 9 being arranged at the bottom end between the polishing cylinder 1 and the lifting cylinder 8, and a return pipe 5 being arranged at the upper end between the polishing cylinder 1 and the lifting cylinder 8.
[0022] The transmission box 4 is fixed to the polishing cylinder 1 by bolts, the output shaft of the motor 15 is fixedly connected to the driving wheel 16, the driving wheel 16 is connected to the driven wheel 18 by a belt 17, the motor 15 drives the driving wheel 16 to move, and the driving wheel 16 drives the driven wheel 18 to rotate through the belt 17.
[0023] The screw shaft 12 is rotatably installed in the lifting cylinder 8. One end of the screw shaft 12 is fixedly connected to the driven wheel 18. The driven wheel 18 drives the screw shaft 12 to rotate, thereby lifting the rice.
[0024] The material guide pipe 9 and the return pipe 5 are both welded between the polishing cylinder 1 and the lifting cylinder 8. The material guide pipe 9 and the return pipe 5 are both inclined and their inclination directions are opposite. The rice from the polishing cylinder 1 enters the lifting cylinder 8 through the material guide pipe 9, and the lifted rice is then injected into the polishing cylinder 1 through the return pipe 5.
[0025] A connecting shaft 13 is installed in the polishing cylinder 1, one end of the connecting shaft 13 is fixedly connected to the driving wheel 16, and a polishing rod 10 is installed on the outer wall of the connecting shaft 13 by screws. The driving wheel 16 drives the polishing rod 10 to rotate through the connecting shaft 13 to polish the rice.
[0026] A guide plate 11 is welded to the bottom end of the polishing cylinder 1 and is arranged obliquely. A discharge pipe 7 is fixed to the top of one side wall of the lifting cylinder 8. Solenoid valves 6 are installed on both the return pipe 5 and the discharge pipe 7. The guide plate 11 allows rice to be injected into the lifting cylinder 8 through the guide pipe 9, and the polished rice is discharged through the discharge pipe 7. The solenoid valve 6 controls the on-off of the discharge pipe 7 and the return pipe 5.
[0027] A vacuum cleaner 2 is fixed on the side wall opposite to the polishing cylinder 1 and the lifting cylinder 8. A dust suction pipe 3 is installed on the vacuum cleaner 2. The other end of the dust suction pipe 3 extends to the inside of the polishing cylinder 1. A filter 14 is installed at one end of the dust suction pipe 3. During the polishing process, the vacuum cleaner 2 absorbs the dust generated through the dust suction pipe 3, and the filter 14 can block the rice.
[0028] The working principle of this device is as follows: When an external power source is connected, rice is poured into the polishing drum 1. During the polishing process, the solenoid valve 6 on the return pipe 5 opens and the solenoid valve 6 on the discharge pipe 7 closes. At this time, the motor 15 drives the driving wheel 16 to rotate. On the one hand, the driving wheel 16 drives the polishing rod 10 to rotate and polish the rice. Then, the rice is injected into the lifting drum 8 under the action of the guide plate 11 and the guide pipe 9. On the other hand, the driven wheel 18 is driven by the belt 17 to rotate. The driven wheel 18 drives the spiral shaft 12 to rotate, which can lift the polished rice and re-enter the polishing drum 1 through the return pipe 5 for polishing. This method allows the polishing rod 10 to fully contact the rice, thereby ensuring the polishing effect of the device. At the same time, the vacuum cleaner 2 absorbs the generated dust through the dust suction pipe 3, and the filter 14 can block the rice. After polishing is completed, the solenoid valve 6 on the return pipe 5 closes, and the solenoid valve 6 on the discharge pipe 7 closes. The polished rice is discharged through the discharge pipe 7.
