Description

[Detailed explanation of the idea] The present invention relates to a grain sorting plate structure in a swinging sorter.

That is, the grain sorting plate is tilted in the vertical and horizontal directions and is installed to feed the mixed rice from the upper end of the vertical slope and separate and sort it from the lower end of the vertical slope, and swings diagonally and horizontally. In a swing sorting machine that can be freely installed and configured,
To improve sorting performance so that mixed rice to be supplied is reliably and well separated into brown rice and paddy, and to provide a simple structure that can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the entire swing sorting machine, in which a large number of grain sorting plates A each having a rectangular shape are stacked one on top of the other and supported by each swinging support rod 5 below, and the motor, eccentric wheels, etc. are the same as before. Each grain selection plate A is installed so as to be swung diagonally and laterally by a drive device 6,
The tank 7 connected to the vertically inclined upper side end A of each grain sorting plate A is installed so that mixed rice can be supplied from the upper supply hopper 8, and the vertically inclined lower side of each grain sorting plate A is installed. A brown rice receiving trough 9, a mixed rice receiving trough 10 and a paddy receiving trough 11 are arranged side by side in the lower part approaching the end opening so that the rice can be taken out.

Each grain sorting plate A is installed so as to be tilted in the vertical direction and in the horizontal direction so as to be swingable at a fixed swing angle in the horizontal direction as described above, and the vertically inclined lower side end is Except for the opening, side plates 12 are provided in an upright manner around the other three parts, and the outlet 13 of the tank 7 can be seen from the vertically inclined upper end (A) and the horizontally inclined upper end (C). Each has its own structure.

In addition, an assumed line L is drawn from the vertically inclined upper side end A to the vertically inclined lower side end opening of each grain sorting plate A, and the horizontally inclined upper side end is partitioned by the assumed line L at the end opening. The width from the hypothetical line L at the upper end of the slope A to the horizontally inclined upper side edge C is narrower than the horizontal length M from the upper end of the slope to the upper end C, and the width from the hypothetical line L to the end C is narrower in the vertical direction. The shape gradually becomes wider toward the lower end of the inclination, and a large number of convex portions 3 on the rough surface 1 from the assumed line L to the upper end C of the lateral inclination are formed along the assumed line L.
It is shaped so that it is larger than each of the many convex portions 4 on the rough surface 2 toward the lower end 2 of the laterally inclined lower side, and so that one rough surface 1 has a higher resistance than the other rough surface 2. However, the rough surfaces 1 and 2 can also be shaped with recesses.

Further, the shape may be such that the size of the convex portion or the concave portion is gradually changed in the vicinity of the hypothetical line L.

During operation, when the mixed rice is fed from the outlet 13 onto each grain sorting plate A that swings in the diagonal horizontal direction as shown by the reciprocating arrow In a state where it flows while gradually expanding laterally toward B,
The grains are actively stirred by the rough surface 1 with high resistance, causing the paddy to float on the upper surface and quickly flow down to the rough surface 2 with low resistance on the lower side of the lateral slope, and the brown rice is placed on the upper side of the lateral slope. By shaking it to the side, the layer is thickened and the paddy and brown rice are quickly separated, and on the second side, the layer is thinner and has less resistance, so only the brown rice mixed in the paddy is shaken up. Paddy can be separated satisfactorily and efficiently.

In particular, as the mixed rice gradually spreads laterally and flows toward the lower side of the slope, the brown rice also gradually spreads laterally and is separated and distributed, and the rough surface 1, which has a large resistance, should also be shaped so that it gradually spreads. This allows the separation ability to be improved.

In this way, the present invention forms a convex or concave rough surface on the surface of the grain selection board, and also forms a horizontally inclined surface on the grain selection board from the upper side of the vertical slope to the lower side of the slope. Draw a hypothetical line in which the width on the upper side of the slope gradually increases, and the convexity or concavity of the plate surface on the upper side of the horizontal slope from the hypothetical line becomes larger than that on the plate surface on the lower side of the horizontal slope, thereby creating resistance. Since the rough surface has a large resistance, it is possible to sufficiently stir the mixed rice, float the paddy with a light specific gravity, and make the paddy flow smoothly toward the rough surface with a low resistance. The rough surface, which has a high resistance and gradually widens as it is divided by lines, can reliably separate the layers of brown rice over a wide range and reliably separate the paddy, improving special performance and making it easy to use. It has the advantage of being able to be suitably implemented in a structured manner.
