TECHNICAL FIELD

[0001] The present application belongs to the technical field of rice transportation and processing equipment, and particularly relates to a rice bran removing device. BACKGROUND

[0002] In the prior art, the main way to remove rice bran is to blow air on one side during the falling process of the lifted rice, so that the bran is separated from the rice. However, due to the uniformity of the falling rice and other factors, the effect of one-time bran removal is poor, and the rice needs to be lifted and fallen again, which is time-consuming and laborious.

[0012] Preferably, the bottom end of the casing is provided with supporting legs.

[0013] When the rice bran removing device is used, the rice falls into the chute after entering the feeding port, and the control groove reciprocates to make the rice fall through the dropping hole more easily after falling on the chute. Due to the size limitation of the dropping hole and the movement of the chute, the rice in the position where the rice falls more will move to the position where the rice falls less and fall through the dropping hole in the position where the rice falls less. In this way, the rice falls through the chute relatively uniformly, and the airflow generated by the operation of the fan at the air inlet flows through the space between the falling rice. Since the bran in the rice is relatively light, the rice is slightly affected by the airflow and continues to fall, and the bran is carried by the airflow and discharged through the air outlet, thereby realizing the separation of the bran and the rice. The rice falls through the chute relatively uniformly, thereby relatively improving the bran removing effect. BRIEF DESCRIPTION OF DRAWINGS

[0017] The rice bran removing device has the following advantages. When the rice bran removing device is used, the rice falls into the chute after entering the feeding port. The electric telescopic device drives the chute to reciprocate, so that the rice is more likely to fall through the discharging hole after falling on the chute. The diameter of the discharging hole is larger than the diameter of the ordinary rice, generally between 0.7 cm and 2 cm, so as to ensure that the rice can smoothly fall through the discharging hole. Due to the size limitation of the discharging hole and the movement of the chute, the rice in the position with more discharging will move to the position with less discharging and fall through the discharging hole in the position with less discharging. In this way, the rice falling through the chute is relatively uniform. The airflow generated by the operation of the fan at the air inlet flows through the space between the falling rice. Since the bran in the rice is relatively light, the rice is hardly affected by the airflow and continues to fall. The bran is carried by the airflow and falls into the bran collecting chamber through the air outlet. Finally, the bran is collected and processed through the bottom of the bran discharging port. In the process of continuous falling of the rice, the airflow generated by the air blower enters the shell through the annular air supply pipeline and the air vent. When moving upward, the airflow has a certain buoyancy on the falling bran, slows down the falling speed of the bran in the shell, and thus can improve the probability of the bran passing through the air outlet in cooperation with the airflow generated by the fan, further improving the bran removing effect. The rice continues to fall on the rotating disc. When the rotating disc rotates under the action of the motor, the centrifugal force makes the rice falling on the rotating disc accelerate and move outward. In the process of moving, the rice is subjected to the friction of the rotating disc and the blocking and friction of the shell, so that two or more rice grains that are extruded or adhered together can be easily separated, so that the bran between them is separated and floats under the action of the airflow of the air blower and is brought into the bran collecting chamber in cooperation with the airflow of the fan. The structure is also applicable to the case where a small amount of bran is wrapped on the rice and is not separated. The friction of the rotating disc and the blocking and friction of the shell can facilitate the separation of the bran wrapped on the rice from the rice, thereby improving the bran removing effect of the device. The falling rice finally enters the rice collecting chamber through the discharging port under the action of the centrifugal force of the rotating disc and is finally collected through the rice discharging port.

[0018] Therefore, the rice bran removing device provided by the embodiment greatly improves the bran removing effect and meets the needs of people without the need for secondary lifting and falling of the rice.

[0019] In actual production, an electric gate can be installed at the discharging port position to control the intermittent opening and closing of the electric gate to control the intermittent entry of the rice into the rice collecting chamber. In the above embodiment, the distance from the position of the rotating disc corresponding to the air vent to the center of the rotating disc is preferably equal to the radius of the annular channel. In order to support the shell, support legs 100 can also be provided at the bottom end of the shell. Generally, four or three support legs are provided, which is well known to those skilled in the art and will not be described here.

[0020] It should be noted that in the above embodiments, the chaff collecting chamber can not be provided, and the chaff can be directly collected at the air outlet or naturally fall after being discharged at the air outlet for centralized treatment. Similarly, the rice collecting chamber can not be provided, and the rice can be directly collected at the discharge port or naturally fall to be collected below.
