Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to a fried helix in which spiral blades are wound around the outer circumference of a cylindrical body inside an outer shell, and the fried helix is concentrically inserted. The present invention relates to a vertical grain sorter that stores a sorting net body provided with a large number of small holes and supplies unsorted grains to the base of a fried helix to sort while fried.

"Prior Art" In a vertical grain sorter, as shown in FIG. 6, a structure in which an upper cover plate 2 of a fried helix 1 is depressed to form a recess 3 is generally formed. It is unavoidable that the grain G accumulates, and if it is not removed and remains as it is, the grain absorbs water and rots. Therefore, it has to be cleaned every time it is used, which is very complicated.

As an example of a countermeasure against this, for example, the actual Kaisho 6
There is one disclosed in JP-A-1-8484.

According to the publication, as shown in FIG. 7, the upper peripheral edge portion of the lid plate 2 covering the upper end portion of the fried helix 1 is joined to the fried helix 1 from the central portion of the lid plate 2. It is characterized in that it is formed on the inclined surface 2a which is inclined upward toward the standing edge 1a. Then, the grain G to be deposited in the recess 3
Is to be repelled from the recess 3 along the inclined surface by centrifugal force.

[Problems to be Solved by the Invention] However, in the conventional technique disclosed in Japanese Utility Model Publication No. 61-8484, the upper edge of the fried helix 1 and the lid plate 2 are
The joining portion 1a with and is joined with an extremely small contact area.

Since the fried helix rotates at a considerably high speed, the lid plate 2 is a pivotal support at the upper end of the fried helix, and both are made of thin steel plates. The minimum contact area of the joint with the plate 2 poses a problem in terms of durability.

The present invention has been made by paying attention to various problems in the conventional technique as described above, and it is attempted to deposit in the concave portion of the lid plate while sufficiently maintaining the bonding strength between the fried helix and the lid plate at the upper end. It is an object of the present invention to provide a vertical grain sorter in which the desired grain does not remain.

"Means for Solving the Problem" The gist of the present invention for achieving such an object is to provide a fried grain spiral body in which spiral blades are wound around the outer periphery of a cylindrical body inside an outer shell body, A selection net body that concentrically inserts the grain spiral body, and a driving means that relatively rotates the fried food spiral body and the selection net body, and the lid plate that covers the upper end portion of the fried food spiral body is the cylindrical body. In a vertical grain sorter in which a recess is formed by folding along the inner peripheral surface of the upper end of the above, while forming the recess of the lid plate entirely horizontally, the folding vertical surface is folded vertically, and this is folded vertically. The vertical grain sorter is characterized in that a plurality of grain discharge ports are formed in the lower portion.

[Operation] When an unsorted grain is supplied and the vertical grain sorter is operated, the fried helix spits in the radial direction by centrifugal force while scooping the grain upward. Then, the small grains pass through the sorting net, and the good grains are sent upward by the spiral blade,
It is released to the outside.

The good grains that have been ejected outward near the upper end of the fried helix fly outward beyond the crown of the sorting net, but the movement of the good grains in this part is complicated, and some grains The grains hit the ceiling plate and fall, and accumulate in the recesses in the upper lid plate of the fried helix.

The concave portion of the lid plate of the fried helix makes the spiral blades of the fried helix close to the ceiling plate as much as possible, while the driving means of the screening net also serves as the upper pivot of the fried helix at the same time. It is provided in order to equip the penetrating portion penetrating the plate with a pivot bearing of the fried helix.

Then, the grains accumulated in the recess of the lid plate are discharged outward from a plurality of outlets formed in the folding vertical surface of the recess by the centrifugal force generated by the rotation of the fried helix, and are accumulated in the recess. do not do.
