Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention promptly separates the selected grain supplied to the supply side of the selection plate into the brown rice layer, the mixed rice layer and the paddy layer during the discharge side, and promptly separates the selected brown rice, mixed rice and paddy. The present invention relates to a grain sorting device which is discharged to a plant to improve sorting ability.

[0002]

[Prior art]

 Conventionally, under the condition of being inclined from the supply side to the discharge side, while the selected grain is transferred from the supply side to the discharge side due to the circular movement of the selection plate, the brown rice layer, the mixed rice layer and the paddy layer are removed. A grain sorting device which discharges the selected brown rice, mixed rice, and paddy from the discharge side after the layers are separated is known from, for example, Japanese Utility Model Publication No. 5-22078.

[0003]

[Problems to be solved by the device]

 By the way, in this type of grain sorting apparatus of the past, the sorting plate was configured to move circularly under the condition that its four corners were suspended by four suspension rods. Perhaps one of the hanging rods causes irregular motion and unexpected vibration, or the circular motion of the sorting plate allows the fed sorted grains to be accurately identified. Since it is impossible to separate the brown rice layer, the mixed rice layer and the paddy layer into the brown rice layer, mixed rice is mixed into the brown rice and a large amount of paddy is mixed into the mixed rice, which obviously deteriorates the selection performance. However, the discharge transfer speed of the selected brown rice, mixed rice, and paddy is slow, and as a result, it is impossible to improve the selection ability.

The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to prevent vibration from occurring as much as possible and to separate the selected grains into a brown rice layer, It is possible to accurately separate the mixed rice layer and the paddy layer so that they can be distinguished from each other, and at the same time, the selected brown rice, mixed rice and paddy can be quickly discharged from the discharge side to increase the selection ability. An attempt is made to provide a grain selection device that can be used.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the grain sorting apparatus of the present invention is arranged such that the feeding side of a sorting plate inclined from the feeding side to the discharging side is supported by an eccentric vertical shaft of an eccentric turning device to make a circular motion, and the discharging side. Is supported by two oscillating rods, and the discharge side is pivoted back and forth diagonally in the vertical direction along with the circular motion of the sorting plate, and is horizontally swung to the left and right. One end of a restriction rod for restricting is regulated.

[0006]

[Action]

 In the figure, when the eccentric turning device is started to rotate the eccentric vertical shaft pivotally attached to the supply side to make a circular motion, and at the same time when the selected grains are supplied to the supply side, the selected grains are discharged from the supply side to the discharge side. It will be gradually diffused towards.

By the way, since the discharge side of the sorting plate is supported by two swinging rods and one restricting rod is connected, the discharge side is slanted vertically with the circular movement of the sorting plate. While swinging back and forth, it swings sideways in a certain range in the left-right direction.

[0008] As a result, brown rice having a large specific gravity is in the lower layer due to the forward and backward oscillating action in the oblique vertical direction while the selected grains diffused by the circular motion of the sorting plate are transferred from the supply side to the discharge side. The paddy that settles and has a low specific gravity is separated so as to float to the upper layer, and at the same time, the brown rice that settled in the lower layer pushes up due to contact with the protrusions provided on the surface of the sorting plate and laterally swivels horizontally on the discharge side. Depending on the operation, the brown rice layer can be accurately separated, for example, to the left position when the sorting plate is rotated in the time direction in Fig. 1, the mixed rice layer to the center position, and the paddy layer to the right position. To be done.

Then, the brown rice, the mixed rice, and the paddy that have been separated and sorted as described above are promptly discharged by the lateral swinging action in the lateral direction over the regulated range on the discharging side. Therefore, even if the selected grains are continuously supplied from the supply side, the selection transfer speed of the selected grains can be increased, so that the selection capacity can be increased.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Permitting that the sorted grains supplied to the supply side can be gradually transferred from the supply side to the discharge side while rapidly diffusing by the circular rotation action of the selection plate, or the swinging motion in the oblique vertical direction on the discharge side By using it, brown rice with a high specific gravity can be settled in the lower layer, and paddy with a low specific gravity can be floated in the upper layer to separate and sort the brown rice layer, the mixed rice layer and the paddy layer reliably. Mixed rice and paddy can be swiftly swung to the left and right on the discharge side to be swiftly discharged from the discharge side to improve the sorting ability. As a result, it is possible to efficiently perform grain selection work in a silent state without causing vibration.
