Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hulling and sorting device that continuously performs a rice sorting operation by rotating a sorting cylinder to remove it.

[0002]

[Prior art]

 Conventionally, there was a technology to separate the rice into brown rice and paddy by continuously rotating the sorting cylinder in one direction and scraping it off.

[0003]

[Problems to be solved by the device]

 In the above-mentioned prior art, when the sorting work is completed, the sorting cylinder is tilted so that the remaining rice inside is dropped and discharged. Therefore, a mechanism for tilting the sorting cylinder and time and labor are required. It is necessary to have a structure to prevent the deformation and damage of the rice, and it is not possible to easily increase the inclination angle of the sorting cylinder due to the above-mentioned problems, so it is possible to improve the efficiency of remaining rice discharge and easily remove dust such as rice bran and discharge it. There was a problem such as no.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is a hulling and sorting device for continuously rotating the sorting cylinder in one direction to remove the rice into brown rice and paddy, in which the sorting rotation direction is on the upper side at the lower side of the inside of the sorting cylinder. In addition to the spiral brush that comes into contact with, and rotates with the rotation of the cylinder, the above-mentioned sorting cylinder is configured to be rotatable in the direction opposite to the rotation of the sorting cylinder. Since the remaining rice is discharged, there is no need to incline the sorting cylinder as in the past, and there is no need for a mechanism to tilt the sorting cylinder and labor, and no need to reinforce each part of the machine. The operability can be improved and the structure of the airframe can be simplified.

Further, in a hulling and sorting device that continuously rotates the sorting cylinder in one direction to remove the rice into brown rice and unhulled rice, the sorting rotation direction upper side and the sorting rotation direction lower side in the lower side of the inside of the sorting barrel. A spiral brush is provided on the lower side of the sorting cylinder, and the spiral brush is arranged on the lower side of the sorting cylinder in the lower side of the sorting cylinder to discharge residual rice. Since the remaining rice is discharged by the spiral brush, there is no need to incline the sorting cylinder and there is no need to rotate the sorting cylinder in the opposite direction, and it is possible to easily install the spiral brush without changing the conventional structural specifications. Since the remaining rice discharging work can be performed only by changing the attachment position of the spiral brush, the handling operation can be simplified.

[Effect of device]

 As is apparent from the above-described embodiments, the present invention is a hulling / sorting device that continuously rotates the sorting cylinder (22) in one direction to remove the rice into brown rice and paddy. The spiral brush (44) that comes into contact with the cylinder (22) and rotates with the rotation of the cylinder (22) is provided on the upper side in the opposite direction to the rotation of the selection cylinder (22). It is configured to be rotatable. Since the remaining rice inside is discharged by the spiral brush (44) guided by the reverse rotation of the sorting cylinder (22), it is necessary to tilt the sorting cylinder (22) as in the conventional case. In addition, there is no need for a mechanism for tilting the sorting cylinder (22) and labor, and no need to reinforce each part of the machine body. Therefore, it is possible to improve handling operability and simplify the machine body structure more easily than before. It is possible.

Further, in a hulling / sorting device for continuously rotating the sorting cylinder (22) in one direction to remove the rice into brown rice and paddy, in the lower side of the inside of the sorting cylinder (22), the sorting rotation direction is good. Side and the lower side of the sorting rotation direction are provided with spiral brushes (44) that can be freely changed in position, and the spiral brush (44) is disposed on the lower side of the sorting cylinder (22) below the sorting rotation direction to discharge residual rice. Since the remaining rice is discharged by the spiral brush (44) on the lower side in the sorting rotation direction, it is not necessary to tilt the sorting cylinder (22), and the sorting drum (22) is rotated in the reverse direction. There is no need to do so, the spiral brush (44) can be easily installed without changing the conventional structure specifications, and the remaining rice is discharged only by changing the attachment position of the spiral brush (44). Since the work can be done, it is possible to easily simplify the handling operation.
