Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a system in which a receiving gutter is inserted horizontally into a sorting cylinder which has a number of recesses formed in its inner circumferential surface and is rotatably hung horizontally. The present invention relates to a sorting barrel in a grain rotary sorting machine that fluidly transfers mixed grains of brown rice and paddy from one end of the barrel to the other end, and separates brown rice and paddy into one stomach during the fluidic transition. In particular, the present invention relates to a sorting cylinder that forms a small recess within the recess to ensure the scooping action of brown rice into the receiving trough.

BACKGROUND OF THE INVENTION In a grain rotary sorter equipped with a sorting barrel having a large number of recesses formed in its inner peripheral surface as described above, the recesses formed in the inner peripheral surface of the sorting cylinder have a hemispherical shape.

For example, the conventional technique is disclosed in Japanese Patent Application Laid-Open No. 58-3681.・By the way, Figure 5 shows paddy and Figure 6 shows brown rice, and the size (L) of the paddy is larger than the size of the brown rice (saddle) at the size ζ (L) fL). Because the paddy is scooped up into the recess shallowly and the brown rice is stuck deep, it is easy for the paddy to come out of the recess, but it is difficult for the unpolished rice to come out, and the unpolished rice is generally scooped up higher than the paddy and falls in a parabola. The conventional technology is to sort by

Therefore, even if it is brown rice, it is not always scooped up to a high level, and like paddy, some of it may escape from the recess at a low level and fall. There is a problem in that it is difficult to completely separate the rice from the paddy, and the sorting action using the recesses has to be repeated σ.

Problems to be Solved by the Invention In the above-mentioned conventional technique, in which paddy and brown rice are placed in the recessed portions, it is difficult to pass through the sorting cylinder once from one end to the other end. It is impossible to completely sort the grains, and the single-gastric action must be repeated, which in turn becomes a factor in the generation of damaged grains.

Therefore, in the present invention, the shape of the recess is unique so that the brown rice stuck in the recess does not fall out of the recess during the scooping operation, and the rice is scooped up with a trench at a high level and then dropped. This is an attempt to solve the above-mentioned problems of the conventional art by preventing the device from falling in the falling area.

Means to Solve the Problems The present invention has been developed by forming a large number of recesses on the inner circumferential surface. In a rotary sorting machine for sorting grain into one stomach, a small recess is formed within a recess formed on the inner circumferential surface of the sorting cylinder.

Function If a small recess is formed within the recess in this manner, if the brown rice gets stuck in the four parts of the mixed grains flowing in the sorting barrel, the end (a) will engage with the small recess as shown in Figure 3. It is scooped up, reaches a high position, and then falls, so it does not fall off on the way. Also, since the end (b) of the paddy is larger than the end (a), it does not engage with the small recess as shown in FIG. 4, and falls during scooping, that is, at a low level.

Therefore, the brown rice does not fall into the area where the paddy falls, and each area where the rice falls is clear. i: The sorting action is carried out reliably.

Embodiment (1) is a sorting cylinder that is supported by a plurality of drive wheels (2) and horizontally mounted so as to be rotatable. (3) is the receiving gutter and this sorting cylinder (1
) is inserted horizontally to form a V-shape, and on the grain scooping side that rotates in the direction of the arrow is a partition plate (4) that can change its tilting position.
It is equipped with

Numerous recesses (5) are formed on the inner circumferential surface of the sorting cylinder (1) and have a hemispherical shape, as shown in Figure 2.
) is formed with a small recess (6).The upper side in the direction of rotation has a steep curve 1Ei (5→), and the slightly lower side has a gentle curve (5 o'clock).

Therefore, when the mixed grains of brown rice paddy flowing in the rotating direction inside the sorting barrel 1) fit into the recess (5), the ends (a) and (b) of the brown rice and paddy are sharply curved. The surface (5a) K easily fits into the recess (5), and the edge of the brown rice among the things that fit in? 'tls (a) is a small recess (6) as shown in Figure 3.
The brown rice itself is stopped by the gently curved surface (6b), is scooped up at a high position, and falls in a parabola into the receiving gutter (3). The end (b) of the paddy does not engage with the small recess (6) as shown in Fig. 4, which is deeper than the brown rice, and the paddy falls during scooping and is completely returned to the sorting cylinder Ql. In this way, while the mixed grains flow and transfer from one end side of the sorting cylinder (1) to the other end side, the brown rice is scooped up into the receiving gutter (3),
The paddy is discharged from the other end of the sorting barrel (1) and is separated into brown rice and paddy.

Effects of the Invention As explained above, the present invention has a system in which mixed grains of brown rice and paddy are collected by inserting a receiving trough into a sorting cylinder which is rotatably hung horizontally and has a large number of recesses formed in its inner circumferential surface. The rotating grain sorting machine has a structure in which a small concave part is formed in the concave part formed on the inner circumferential surface of the sorting cylinder, so that among the mixed grains that fit into the concave part, the edges of the brown rice are smaller than the paddy. ζ and engages in a small recess. The brown rice itself is stopped by the concave @, and is scooped up to a high level without falling during scooping, and falls in a parabola into the receiving gutter, and the end of the paddy does not engage with the small concave part. It fell during scooping and was not reached inside the gutter due to the trench.

Therefore, the falling areas of brown rice and paddy are clearly separated, and since brown rice does not fall into the falling area of paddy, there is no need to repeat the sorting action, allowing early sorting and complete sorting in one pass through the sorting barrel. This also makes it possible to prevent the occurrence of damaged grains.
