Abstract

PROBLEM TO BE SOLVED: To remove bran from grain during sorting by forming grooves in which bran flows down from the oscillating-up side to the oscillating-down side on the plate surface of an oscillating sorting plate on which sorting projected lines are arranged. SOLUTION: On an oscillating sorting plate 15, a lot of sorting projected lines 28 standing in lines are arranged along the vertical direction in which bran flows down. On this plate surface, a lot of grooves 29, 29,< are formed. And the grooves 29, 29,< are formed, inclined so that they may become on the discharge side one by one as they are positioned from the oscillating-up side to the oscillating-down side. In this way, bran generated during sorting flows to the oscillating-down and the oscillating-up side in the grooves 29, 29,< and flows to outside the plate from the oscillating-down side of the termination side, or it is mixed with paddy mixed rice and flows down, and it is sucked and removed to outside a device during air sorting in a hulled rice air sorting path during circulation in a device to prevent bran from being stuck on unpolished rice.

流下する。Next, the sorting state of this embodiment will be described. When mixed rice is supplied to the oscillating sorting plate 15 and reciprocatingly oscillates obliquely up and down in the horizontal direction, as a primary phenomenon, small brown rice having a large specific gravity sinks to the lower layer, and a large brown rice having a small specific gravity. The paddy rises to the upper layer. Next, as a secondary phenomenon, the brown rice that has settled in the lower layer has flowed down on the grain downflow guide surface 28c in an attitude along the downflow direction at the end of the returning movement to the downside, and is pushed. The long axis direction of the brown rice tends to follow the swinging side of the surface 28a. Next, as a third phenomenon, when the plate surface moves upward, the brown rice is pushed and supported by the pushing surface 28a and moves to the upward while being contacted and supported by the pushing surface 28a. Alternatively, it is bounced off the pushing surface 28a and rises along the ascending guide surface 28b.
Move to c. (Note that the grain is also in contact with a portion of the plate surface other than the pushing surface 28a, and moves to the swinging side 15c due to frictional resistance and the like along with the forward movement. The movement will not be described.) Next, as a fourth phenomenon, at the moment when the plate surface returns from the forward movement to the swinging upper side 15c to the swinging lower side 15d, the pushing surface 28a is moved.
Brown rice pushed to the ground and bounced off ascending guide surface 28b
Brown rice that has moved to the swinging side 15c while ascending along is discharged to the swinging side 15c by inertial force. Then
As a fifth phenomenon, the swinging side 1 along the rising guide surface 28b
Brown rice and paddy that are moving upward to 5c, brown rice rises to the lower layer in relation to the difference in specific gravity, and rice rises to the upper layer. The floating paddy flows down on the brown rice layer to the swaying side, and the brown rice and the paddy flow down to the discharging side 15b due to the inclination of the plate surface to the discharging side 15b.

上させることができる。Thus, brown rice is distributed while being drifted on the swinging side 15c, paddy is distributed while being drifted on the swinging side 15d, and mixed rice is sorted while being distributed in the middle. As described above, sorting ridge 2
8 is constituted by a continuous pushing surface 28a, a rising guide surface 28b and a grain falling guide surface 28c which are long in the grain falling direction, so that it is compared with a conventional apparatus in which small-sized sorting uneven portions are arranged in a zigzag manner. And a pushing surface 28 having a grain pushing function.
a can be formed more, and the grain downflow guide surface 28c is formed on the swinging side of the long pushing surface 28a that is continuous in the grain downflow direction, so that brown rice in the long axis direction approaches the pushing surface 28a. The rising guide surface 28b is formed vertically above the grain falling guide surface 28c in a continuous manner in the vertical direction. The pushing action to the upper side becomes large, and when returning to the swaying side, the flow of the lower brown rice to the discharge side is expedited.
Further, the paddy submerging in the lower layer can speed up the floating movement to the surface of the brown rice layer by the pushing action of the pushing face 28a, the rising guide action of the rising guide face 28b, and the specific gravity difference, and can improve the sorting efficiency. .

When supplied from the side closer to d, the mixed rice supplied to the lowermost swinging side 15d moves quickly to the swinging upper side 15c on the pushing surface 28a and the rising guide surface 28b, and moves closer to the uppermost supply side 15a and closer to the uppermost swinging side 15c. Sorting can be started from a nearby location, the length of the swing sorting plate 15 in the vertical direction can be reduced, and the plate surface can be reduced in size. In addition, when supplying to the swinging side 15c side,
Since the sorting can be started from the position of the uppermost supply side 15a and the uppermost swinging side 15c, the size can be further reduced.

The joint on the swinging side of 8b is formed as a sharp corner (even if it is formed as a curved surface, it is formed at least with a radius of about 0.2 mm). With this configuration, the pushing force of the grain to the swinging side at the corner is increased, and the sorting efficiency is improved.

8a is configured to be higher on the supply side 15a and lower sequentially or stepwise toward the discharge side 15b. With this configuration, the mixed rice supplied to the plate surface can quickly form a grain layer thickness on the supply side on the rocking side, and can quickly float the rice on the lower brown rice layer, Can flow down to the lower side quickly, and the sorting efficiency is improved. In addition, since the pushing surface 28a is low on the discharge side, the upper layer of paddy is difficult to be pushed to the rocking side, the brown rice distribution width on the rocking side is widened, and the mixing of rice into brown rice can be reduced.

On the plate surface, the width of the grain flow-down guide surface 28c is configured to be narrower on the supply side and gradually wider toward the discharge side. Therefore, on the supply side of the plate surface, the grains are quickly moved upward and upward, and the brown rice layer thickness can be formed quickly, promoting the flow of the paddy floating on the upper layer to the lowering side, and the discharge side on the supply side. Since the movement of the rice to the rocking side can be reduced, the distribution width of the brown rice on the rocking side can be widened, and the mixing of unhulled rice into the brown rice can be reduced.

It is a configuration that adjusts the angle in the grain flow down direction. In addition, if the sorting frame 30 is configured such that the angle in the grain flow-down direction with respect to the machine body can be adjusted, the angle adjustment range can be widened by adjusting both angles.
