Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a vertical grain body which is used to sort O grains such as rice, wheat, etc. into large grains, small grains, and waste grains, and to use them for packaging such as grain size O4OT-Shunzume. Regarding sorting ridge O improvement.

Of course, the CK granules may be natural granular minerals or granular industrial products, but below, we will mainly explain rice W&8 sorting for convenience 1. The conventional vertical O-grain separator is disclosed in No. ￰＠＠f+7-, which the present applicant previously applied for.
1 shown in Figure 1, Kuushin/1P1ec circular sorting network! At the same time, 1 is installed on the circular part of the snow body.
Spiral jlL30t@Attached shaft 4 is arranged *@Spiral winged shaft 4 companies, gear
The sorting net 2 rotates once in the opposite direction to the shaft 4 when it is obstructed, for example, through ll0r1>mO, and the grains are input from the grain input lower. The grains are placed on the spiral wing 30, and the spiral 313001i11iKL rises to %A.
(At the time of sledding, the grains receive force from the upper surface 301 of the spiral blades 300 and are pressed against the farbetsu rope body. Sorting net body =
The rope! IL#i, small OII grains and broken waste grains pass through, but large grains OI & So do not pass through - to the rope turn 1 of a predetermined size! 'b,..., so 1
The small waste 11iI#i in the lsI detail passes through the net 111Th1 and jumps into the sieve area Hatakeen, and is taken out from the small export outlet Shizuka, but the uppermost blind τ of the large comparison O*m#i rises. It flows into the hopper 11 from the pottery production area 10, and the hopper 11
The structure was such that the 41st piece of large grain [2], which was selected as the inner KII, was taken out from a 1m outlet.

However, since the subordinate reed O spiral blade 30 is made of a flat and smooth metal plate such as a steel plate, as the spiral blade 30 rotates, the grain group rotates over the spiral blade 30! It glides smoothly while turning. Therefore, the grain group rose smoothly, drawing a spiral with a large pitch, and rising from the lower part to the upper part 7j in a relatively short time. As a result, the locus (spiral shape) drawn by the contact point between one grain group and the net 2 tortoise between 0 and 1 dl on the platform from the bottom to the top becomes short, and the small waste grains The trench that is not sorted is large @ 0 grains Kll
As a result, the waste was collected from the take-out area 10 into the hopper 11 yen, and its sorting function was poor. The upper surface 30m of the spiral member 30 is smooth. Ninth, the grain group has spiral wings 3
Since it is difficult to obtain enough Tatsushin Rikikan from 0, Tsuna 2a
Strong K (low opening of pressed grains)

The present invention addresses the drawbacks of the conventional Jlffl grain comparison machine as described above. 4. It is an object of the present invention to provide an excellent hazard separation machine that can dramatically improve the sorting performance by adding a modified JL blade to the spiral blade. Embodiments of the present invention will be shown. The vertical granule sorting machine according to the present invention (hereinafter referred to as the present invention sorting machine) will be explained below based on the drawings.As shown in No. 161K, the vertical granule sorting machine has nine cylindrical sorting nets 2 installed in a casing 1, and The shaft 4K) is built in the sorting rod 2 and rotates once relative to each other, as shown in FIGS. 2 to 6. At least a portion of the upper surface 3 & of the spiral wing 3 screwed to the metal plate 7 is made of a metal flat plate having a large dynamic friction resistance area. II! In the example shown in IIK, the Mayuki table @@13
is provided by forming a large number of small protrusions 14, 14'... on the spiral tube, so that it contains a dynamic frictional resistance greater than the dynamical frictional resistance of the metal flat plate. In the implementation shown in FIG. 113, the surface layer 13 has a large number of small holes 15.

It is designed to form a dynamic frictional resistance t.
-I'm making a large pot. In the embodiment shown in @4, the surface layer 13Fi has a large number of protrusions 16.16. ...
A pipe is provided on the upper surface 3aK of the snowboard 3, and exhibits a large dynamic frictional resistance.

It is desirable that the protrusions 1iFi be formed in a direction perpendicular to the direction of rotation as shown in the figure to increase the dynamic frictional resistance.In the embodiment shown in FIG. O groove 17, 17. . . . It is provided from C and K which are perforated on the upper surface 3aK of the spiral blade 3, and a larger dynamic frictional resistance is obtained, making it h15. Furthermore, is Mukuju 17 perpendicular to the first turn direction? ! ! at1. It is desirable to make the dynamic friction resistance pipe larger.

Furthermore, in the embodiment III shown in FIGS. 2 to 185, the small projections 14. Small hole 15. The height and width of the ridge 16 and the width 170 are TNT of 0 ml of grain, and the small protrusion 14, the small hole tS, the ridge 1 and the groove 1.
The mutual spacing between the seven comrades is preferably about 1 to 3 times the diameter of the grain SOW.

In the example shown in aSS, the 13 *face layer companies,
There is a soft elastic plate 18 which has the highest dynamic frictional resistance compared to soft rubber or sponge material. It is saddled using. Soft elastic plate 111 [)
The surface may be smooth or may have an uneven shape. Alternatively, the spiral blade 3 and the shaft 4 may be made of a hard rubber body and integrally formed into an m-shape, and the surface layer 13 may be formed.

Note that a large dynamic friction resistance tube is not required for the spiral wing 30 (for example, the 3 parts of the spiral blade existing in the take-out area 10 only perform the iii Zing action, and the 411 that performs the sorting action is not). ht) τ does not need to be applied to the surface layer 13. Moreover, the small protrusion 14. Small hole 16, protrusion 11
1. Hisashi 17 is definitely on Snowy Iral Tsubasa 30 @3*,
It is not necessary because it is provided with a uniform distribution device, and the part near the outer edge of the spiral blade 3 has a high distribution density, and the part of the spiral blade 3 close to the axis 4 has a distribution density of 11 low (11). The operation of the sorting machine of the present invention having the above-mentioned configuration can be explained as follows. As shown in the seventh factor, the spiral wing 3 turns once as shown by the white wax arrow, so the grain group placed on it is rising. A centrifugal force is applied from the upper surface 3a, and the net 2aK of the sorting net body 2 is pressed against it.

At that time, the upper 113m is the dynamic friction resistance of the conventional flat metal plate of 1
Since the surface layer 13 has a large dynamic frictional resistance, the grain group receives a larger centrifugal force from the surface layer 13 and is strongly pressed against the net 2. As a result, small and medium-sized rice is separated better than before, and the sorting performance is improved. Furthermore, as mentioned above, the dynamic frictional resistance of the top surface 3a of the spiral is large, so the grain group does not slide smoothly on the top surface 3& of the scissors, so *sas+p does not rise smoothly and it is difficult to The length of the trajectory (spiral) of the part where the grain group comes into contact with the net 2a is ij and %. There are enough opportunities for small rice and waste rice to be sorted out with one in every two nets (sortability is 11!).
will improve.

Furthermore, since the dynamic frictional resistance of the upper surface 3a of the spiral blade is large, as shown in FIG.
As X, YK rotates and moves as shown, Tori → Island,
As shown in False→False→c, (and a mutual deviation occurs (the sth factor has been simplified to make it easier to understand).As a result, the grain The group tends to rise while being stirred (so C, tLK also increases the sortability III!

IO selective iIF! Compared to the conventional 031 performance of about 6 degrees, this has greatly improved to about 9891.

From the above, it is clear that the sorting machine of the present invention has a large front frictional resistance on the upper surface of its spiral blades, so that the particles are strongly pressed against the net, and the particles are sufficiently separated. (Since the mesh KMk is in contact with the KL< stirrer, it is an excellent granule sorter with much improved sorting performance compared to conventional ones.
