Abstract

DC60 (15/10/45) A rotary oscillating separator consisting of 4 separating containers, each with 5 conical separating plates arranged within the containers, and 6 drive paths for rotary oscillation. In these 4 separating containers, a mixture of unhulled and unmilled rice is fed onto the separating plates in the containers at the designated area for separating the unhulled and unmilled rice. The unmilled rice is discharged through the raised perimeter of the container, and the unhulled rice is discharged through the central bottom of the separating container. The drive paths consist of several oscillating drivers arranged at evenly angular intervals around the 4 separating containers. Each of these oscillating drivers is tilted upwards and functionally connected to the raised perimeter of the separating containers to support the containers. These oscillating drivers are sequentially activated at a predetermined delay phase to generate the oscillating motion that will be transmitted. To the separating container, each of the aforementioned oscillating drives, which consists of an oscillating angle adjustment mechanism 40 for fixing the oscillating drive to an upward tilt and for varying the oscillating angle in the rotation of the separating container. The rotary oscillating separator, which consists of 4 separating containers, each with 5 conical separating plates arranged in the container, and 6 drive paths for rotary oscillation. In the 4 separating containers, a mixture of unhulled and unmilled rice is fed onto the separating plates in the separating containers at the designated area for separating the unhulled and unmilled rice. The unmilled rice is discharged through the raised perimeter of the container, and the unhulled rice is discharged through the central bottom of the separating container. The drive paths consist of a number of oscillating drives arranged at evenly angular distances around the 4 separating containers. Each of these oscillating drives is tilted upward. The upper part is functionally connected to the raised perimeter of the separating container to support it. These oscillating drives, sequentially activated at predetermined phases of the delay, generate oscillatory motion that is transmitted to the separating container. Each oscillating drive contains a 40° oscillation angle adjustment mechanism for fixing the drive at the upward tilt and for varying the oscillation angle in the rotational oscillation of the separating container.
