Description

[Detailed Description of the Invention] Conventionally, a sorting cylinder is rotatably installed horizontally, with a large number of depressions formed in its inner peripheral surface, one end of which is a supply side for grains to be sorted, and the other end is a discharge side. In addition, in a rotary sorting machine equipped with a receiving gutter for taking out sorted grains scooped up by a recess in the sorting cylinder, the sorting cylinder is placed in a substantially horizontal position or in a gently inclined position with the discharge side slightly lowered. The grains to be sorted are continuously supplied to the supply side, and the sorting action progresses gradually from the supply side to the discharge side, and the layer of grains to be sorted flowing on the inner peripheral surface becomes thinner. The scooping action by the depressions was poor, resulting in a decrease in efficiency.

Therefore, the present invention provides slanted return plates arranged evenly on the internal circumferential surface of the sorting cylinder on the discharge side, with the upper side in the rotational direction of the cylinder close to the discharge end, and an adjustment plate connected to the upper part of the receiving gutter. The upper edge of the plate is configured to be higher on the discharge side than the other parts, and the above-mentioned conventional There is a VC to obtain a rotary sorting machine that aims to eliminate the drawback of reduced sorting efficiency and improve sorting efficiency and sorting accuracy.

This will be explained below with reference to embodiment figures. In the explanation in the text, the grains to be sorted are mixed grains of paddy and brown rice.

That is, (+1 is a sorting cylinder with a large number of holes (a) formed on its inner circumferential surface, and rollers (2) and (2) are rotated by an appropriate drive device.
3), it is supported in a substantially horizontal position, with one end being the mixed grain supply side (X) and the other end being (Y). (4) is a receiving gutter which is installed within the sorting cylinder (1) over the length of this cylinder (11), and has a built-in screw conveyor (5) for taking out the sorted brown rice. (6)・(
Reference numerals 7) denote a receiving side plate and a receiving collecting plate constituting the receiving gutter (4), each of which extends obliquely upward. (8) is an adjustment plate which is connected to the upper part of the receiving side plate (6) and has a lower edge pivoted at the upper end of the side plate (6) so that the inclination posture can be changed, and (9) is the adjustment plate. This is a lever that changes and adjusts the attitude of the plate (8).

OQ is an adjustment auxiliary plate welded to the upper edge of the adjustment plate (8) on the discharge side (Y) part of the sorting cylinder (1) at a substantially right angle to this adjustment plate (8) when viewed from the side; As a result, the upper edge Qll of the adjustment auxiliary plate 01 becomes higher than the upper edge f13 of the adjustment plate (8).

In addition, a3 is a return plate, which is arranged equidistantly on the inner peripheral surface of the discharge side (Y) of the sorting cylinder (11). The upper side (shown in a) is slanted closer to the discharge end (141).

In addition, in order to make the adjustment plate (8) on the discharge side (Y) higher, the adjustment auxiliary plate 01 was welded to the discharge side (Y) part, but the upper edge +IZ of the adjustment plate (8) and the sorting cylinder (1) The distance from the inner circumferential surface on the discharge side (Y) may be wider than that on the supply side (X) and the central portion (other portions).

+151 is the mixed grain tank, (161 is the brown rice removal gutter, (1
71 is a paddy dumping trough.

Next, to describe the operation, if the wheels (2) and (3) are rotated by an appropriate drive device, the sorting cylinder (1) is rotated at a low speed in the direction shown by the arrow (A). At the same time, the screw conveyor (5) also rotates and the lever (9) is operated to set the adjustment plate (8) to an appropriate tilted position, so that the mixed grains sequentially introduced into the mixed grain tank sower are continuously sorted through the sorting cylinder (1 ) on the supply side (
X) If the mixed grains are allowed to flow into the inner circumferential surface, immediately after the mixed grains flow, they will appear to be in a stagnation state and become bulky, but after that they will gradually spread out and the brown rice will sink to the bottom layer of the paddy and form a depression (a). As shown by the arrow (b) in Figure 2, the water gets stuck and is scooped up, goes over the soil of the adjustment plate (8), falls to the receiving side plate (6) or the collecting plate (7), falls to the soil, and collects in the receiving gutter (4). be done. Then, the brown rice and paddy that cannot be scooped out flow toward the discharge side (Y) while repeating rising and falling states on the inner peripheral surface of the sorting cylinder (+1), and are gradually sorted by being scooped up in the depression (a). As the action progresses and reaches the discharge side (Y), the layer of mixed grains becomes thinner, but the diagonal return plate (
By the rotation of 131, the mixed grains are returned to the supply side (fx) and are appropriately retained, and the layer of mixed grains flowing on the inner peripheral surface of the sorting cylinder (1) is maintained in a layer of the same thickness. drooping The return plate Q3 also performs a stirring action on the mixed grains, floats the paddy that has settled to the lower layer to the upper layer, and promotes the scooping action of the brown rice by the depression (a).

On the other hand, the return plate +131 performs a lifting action as well as a stirring action on the mixed grains, but since its upper edge aυ is located at a high position by the auxiliary adjustment plate OQ, the flow into the receiving gutter (4) is blocked and the third As shown by the arrow in the figure (・→, the sorting cylinder (11) falls to the bottom of the inner peripheral surface, and only brown rice is indicated by the arrow), the receiving gutter (4)
The paddy falls from the discharge end 04 and is taken out of the machine from the paddy removal gutter (lη), and the brown rice is taken out from the brown rice removal gutter (16) together with the brown rice that has flowed into the receiving gutter (4). .

As explained above, the present invention has a sorting cylinder formed with a large number of depressions on its inner circumferential surface, one end of which is a supply side for grains to be sorted, and the other end of which is a discharge side, which is rotatably installed horizontally. In addition, in a rotary sorting machine equipped with a receiving gutter for taking out sorted grains scooped up by the recess in the cylinder, an upper side in the rotational direction of the cylinder is attached to the inner circumferential surface of the sorting cylinder on the discharge side. Slanted return plates close to the discharge end are arranged at equal intervals, and the upper edge of the adjustment plate connected to the upper part of the receiving gutter is set so that the discharge side is higher than the supply side and the central part. At the discharge side of the body periphery, that is, at the end of the sorting action, the grains to be sorted are kept at a suitable level to maintain a thick layer of flowing grains to be sorted, and this layer is also stirred to float the rice. At the same time, the auxiliary adjustment plate prevents grains to be sorted thrown up by the return plate from flowing into the receiving trough, and by working together with the return plate, it is possible to improve sorting efficiency and sorting accuracy.
