A circumferential gap having a distance equal to or larger than the grain diameter is provided between the grain and the circumferential wall, and a moderate amount of grain leakage occurs from the circumferential gap. The grains that have leaked out are again subjected to the lifting and sorting action on the upper surface of the lower spiral blade, and this situation occurs continuously throughout the spiral blade. In this way, the circulation rate of grains, that is, the chance of sorting is increased, and the sorting accuracy is improved. In addition, due to such grain leakage, excessive rotational force or lifting force caused by the spiral blade can be avoided, so grains (especially when sized) can be avoided.
This prevents damage and improves yield.

。First, the overall structure of the vertical grain sorter will be explained in more detail based on FIG. The inside of the outer shell 1 erected on the base 7 is divided into a lower grain supply area 2, an intermediate sorting area 3, and an upper grain removal area 4. is separated by a lower partition plate 5, and the sorting area 3 and extraction area 4 are partitioned by an upper partition plate 6, so that the small waste grains sieved out may not mix into the unsorted grain group, It is designed to prevent the selected large grains from getting mixed into the waste grain group. A cylindrical grain receiving chamber 14 is fixedly installed directly above the center of the base 7, and the grain supply port 1
The grains to be sorted introduced from step 5 are received at the bottom. The sorting ff18 is a cylindrical body supported in an upright position directly above the grain receiving chamber 14, and is composed of a bottomless lower cylindrical portion 9 facing the supply area 2 and a lidded portion facing the take-out area 4. An upper cylindrical part 12 with a discharge window 13 on its circumferential side, and a perforated cylindrical part 10 facing the sorting area 3 and having numerous sorting holes 11 bored therein.
It forms a shape in which the two are integrally combined. The grain lifting screw 20 is vertically inserted into the lower cylinder part 9, the porous cylinder part 10, and the upper cylinder part 12 of the sorting cylinder 8 from the grain receiving chamber 14, and rotates. It looks like this. As shown in an enlarged view of a part of the grain lifting screw 20 in FIG.
&! 21 protrudes horizontally. In addition, the cough whirlpool 21 is
As shown in FIG. 1, it is provided around the entire length of the rotating shaft 20a. Reference numeral 22 denotes a motor, which applies rotational driving force to the grain lifting screw 20 via appropriate transmission means such as a belt, a belt wheel, and a gear. The rotation speed of the grain lifting screw 20 is 150
It is normal to rotate at a high speed of ~350 to 9 m, but this can be increased or decreased depending on the breakage resistance strength of the grains to be sorted and other circumstances. It is also possible to rotate the body 20 in the opposite direction.

1, the outer edge of the container is the porous cylinder part 10 in the sorting 'w18.
A circumferential gap X is provided at an interval corresponding to about 2 to 3 times the grain diameter with respect to the inner circumferential wall of the grain. In this way, excessive grains will leak from the circumferential gap X to the upper surface of the lower spiral blade during sorting, so the circulation rate of grains, that is, the opportunity to be used for sorting, will increase, and the grains will be sorted after sorting. It is possible to reduce the proportion of waste grains in the grains and improve the sorting accuracy. However, this peripheral gap
If M is made too large, the bulk of the grain group M will be reduced, so care must be taken.

When a rotational force is applied to the grain receiving chamber 14, the grains received in the grain receiving chamber 14 are first subjected to a grain lifting action by the spiral blades 21 of the grain lifting screw 20, and pass through the lower cylinder part 9 of the sorting cylinder 8. Porous cylinder part 1
It is fried to 0. Since the grains are subjected to centrifugal force as well as grain lifting action, they are pushed toward the inner circumferential wall of the porous cylindrical portion 10, but since the porous cylindrical portion 10 is provided with numerous screening holes 11, Among the grains, waste grains with a diameter smaller than the diameter of the sorting hole 11 pass through the sorting hole 11 and are sieved out to the sorting area 3, and are discharged by the lower scraper blade 18 provided on the outer periphery of the porous cylinder part 10. 16, and is discharged to the outside of the outer shell 1. In this way, waste grains are sieved out at the 1° position of the porous cylinder part, and the remaining large grains are lifted and transported to the position of the upper cylinder part 12, and are eventually discharged from the discharge window 13 to the take-out area 4. is guided to the outlet 17 by an upper scraper 19 provided on the outer periphery of the upper cylindrical portion 12 and taken out to the outside of the outer shell 1. However, below the outlet 17 there is a packaging container such as a bag. has been prepared and will be packed inside.

こととなる。(Study of another aspect) By the way, in the above-mentioned example, the spiral N21 in the grain lifting screw 20 was shown as one that projects horizontally in the radial direction of the rotating shaft 20a (hereinafter referred to as a horizontal spiral blade). In this case, it is assumed that the grain lifting body 20 is driven at the optimal rotational speed for the sorting operation. Under the action of centrifugal force, the grain
As shown in the figure, the grains M gather on the inner circumferential wall side of the porous cylindrical portion 10, and the upper surface of the grain group M has an inclination angle θ with respect to the horizontal line. The grains are piled up near the outer edge of the rotor blade 21, and the larger the value of the bulk height h of the grain group M at that time, the more the sorting performance improves. The inclination angle θ increases in proportion to the centrifugal force acting on the grains, and the height of h also increases accordingly, so the faster the rotational speed of the grain lifting screw 20 is, the better the sorting performance will be. do. On the other hand, if the rotational speed becomes too high, the centrifugal force will cause the grains to slam against the inner wall of the porous cylinder part 10, resulting in damage to the grains and a tendency to wastefully increase the number of waste grains. There is even a risk that the function as a machine may be diminished.

It was designated as spiral 1!21a (hereinafter referred to as an inclined spiral wing). Further, a circumferential gap Y having an interval equivalent to 2 to 3 times the grain diameter with respect to the inner circumferential wall of the porous cylindrical portion 10 in the sorting tube 8 was provided at the outer edge of the inclined spiral blade 21a.

象とした場合の実施例によれば勾配角αを１５〜４０°
の範囲としたときに最も効果的であった。The circumferential gap Y of the inclined spiral blade 21a is the same as that of the horizontal spiral blade 21.
It is slightly larger than the circumferential gap X of . Even in this case, if the rotational speed of the grain lifting bee body 20 is the same, the surface inclination angle θ of the grain group M is also kept the same. However, the slope *
& Since the radial sliding frictional resistance acting between the downward slope upper surface of the blade 21a and the grains being lifted becomes smaller,
As the force acting outward increases, the grains slide outward and are deposited in a bulky manner on the inner circumferential wall of the porous cylindrical portion 10, causing the grain group M and the inner circumferential wall of the porous cylindrical portion 10 to The contact area (sorting opportunities) will be expanded. That is, horizontal a'
The bulk height h of the grain group M in the swirler 21 (see Fig. 3)
In contrast, the grain M in the inclined spiral blade 21a of this embodiment
The bulkiness is ha, and an increase of about 10 to 20% is observed. In this case, the slope angle α of the winding rotation W21a is ]0
° or more. If it is less than 10", the above-mentioned effects cannot be sufficiently produced. To specifically determine the slope angle α, it is necessary to press the grain group M against the inner circumferential wall surface of the porous cylindrical portion 10. It is necessary to consider the centrifugal force acting on the grain lifter.The centrifugal force is proportional to the square of the rotation speed of the grain lifting screw 200, and the rotation speed is selected in consideration of the breakage resistance strength of the grains to be sorted.If If the slope angle α is increased while ignoring the balance with the centrifugal force, more grains will leak out from the circumferential gap Y between the outer edge of the inclined spiral blade 218 and the inner peripheral wall of the porous cylindrical portion 10, and the grains will become more concentrated. The bulk of group M shows a tendency to decrease.The key point is that the centrifugal force acting on the grain and the inclined spiral blade 21
The slope angle α is within the range that does not break the balance with the surface frictional resistance of a.
It is a good idea to make the angle α as thick as possible.According to an example in which rice grains are to be sorted, the slope angle α is 15 to 40°.
It was most effective when it was within the range of .

うになる。Such an inclined spiral blade 21a does not necessarily correspond to the grain lifting spiral 20.
It is not necessary to surround the entire length of the It is in the height range of the porous cylindrical portion lO that a substantial sorting effect is exerted on the grains, and therefore, the beveled rotor blades 21a are provided only in the range H shown in FIG. This is because even if the parts are made into horizontal swirling blades 21, the overall sorting performance will never deteriorate. Rather, the horizontal spiral blade f, 21 is superior in grain lifting ability compared to the inclined spiral blade 21a. Therefore, in the grain-lifting bee body 20, the parts that only require the grain-lifting function, such as the parts corresponding to the inside of the lower cylinder part 9 and the upper cylinder part 12, and the part corresponding to the inside of the grain-receiving chamber 14, etc. In this case, a horizontal spiral blade 21 as shown in FIG. 2 may be provided. Therefore, the sorting efficiency is improved accordingly. In particular, the grain-juvenating mosquito bodies 20 rotate smoothly due to reduced frictional resistance due to the grain receiving chamber 14 being filled with grains to be sorted, and the grains to be sorted can be smoothly supplied.

の処理が容易となることである。An additional effect of installing the inclined spiral N21a is that when the grain sorting machine is stopped after the sorting operation is completed, all the grains remaining on the upper surface of the wing will fall off. Since the remaining grains are collected at the bottom of the grain receiving chamber 14, the remaining grains can be easily disposed of.

の優れた利点を有している。"Effects of the Invention" As is clear from the above explanation, according to the navy blue grain sorter according to the present invention, the outer edge of the spiral blade has grains against the inner circumferential wall of the thread hole tube in the sorting tube. Since the circumferential gaps are provided at intervals larger than the grain diameter, the grains being sorted will leak through the circumferential gaps, increasing the chances of sorting and improving the sorting accuracy. Further, since no excessive rotational force or grain lifting force is applied to the grains, breakage of the grains (particularly sized grains) is prevented, and the yield is also improved. Therefore, it has many excellent advantages, such as being able to raise the conventional limit of screening performance from 80 to 85% to 95 to 99% at once.
