Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake device for a vertical grain sorting / adjusting machine capable of sucking and pulling down cereal grains by means of a fryer for fine selection and adjustment and discharging the cereal grains from above.

[0002]

2. Description of the Related Art Conventionally, a net-shaped sorting cylinder having a spirally-floating grained cylinder inside the casing is erected inside a casing having a suction / discharger connected to a lower end thereof. Japanese Patent Application No. 3-375 filed by the applicant of the present invention relates to a vertical grain sorter / adjuster in which discharge blades are provided on the outer peripheral surface of the upper end.
As seen in No. 24, dust and the like generated in the machine casing that is the outer periphery of the net-like sorting cylinder are sucked toward the suction suction / discharger below.

[0003]

However, since the upper side of the casing is sealed, the suction wind generated by the suction duster is weakened, and the suction wind effectively acts inside the mesh-like sorting cylinder. The dust and small grains, etc. are not sufficiently discharged from the reticulated sorting cylinder, or the dust inside the casing is poor.
There was a problem such as poor selectivity.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised so as to solve such a problem and to further improve the selectivity. Therefore, a plurality of upper end surfaces of the casing above the discharge blades are provided. Air suction holes, and mesh selection by suction duster
Negative pressure generated in another cylinder causes the outside
Air to form a flow from the reticulated sorting tube into the sorting room
In addition, each intake hole is formed in an arc shape around the center of the deep-fried grain, or each intake hole is formed by expanding a net.

[0005]

[Effect] Therefore, the suction and exhaust device puts it in the mesh sorting cylinder.
Due to the negative pressure generated, outside air can be sucked into the mesh sorting cylinder from each intake hole on the upper end face, and the suction wind by the suction / dust generator works sufficiently in the mesh sorting cylinder, thereby eliminating dust and the like. This can be effectively promoted, and the selectivity can be further improved.

FIG. 1 is a sectional view of a vertical grain sorting and adjusting machine,
A suction / discharger B is communicated below the lower part of the machine A having a square cross section standing on the carriage 7, and a storage tank 8 is communicated and connected to the upper side of the machine A. In the sorting chamber a inside the casing A, a net-like sorting cylinder 3 in which a frying cylinder 2 having a helix 1 on its outer periphery is installed so as to be freely driven by a lower motor 9 so as to be able to be driven in a mutually reverse manner. Then, the grains supplied from the outer supply hopper are supplied to the inside of the guide cylinder 3a below the mesh-like sorting cylinder 3, so that each support roller 10
On the outer peripheral surface of the upper end portion of the frying cylinder 2 extending further upward than the upper end portion of the net-shaped sorting cylinder 3 supported by a plurality of pieces each of which releases selected kernels into the storage tank 8. The discharge blades 4 are fixedly provided, and a collecting step surface 11 for small grains and the like is provided on the outer periphery of the lower part of the sorting chamber a, and a communication hole 12 communicating with the suction / dust generator B is provided. However, the upper end surface 5 of the casing A above the discharge blade 4
As shown in FIG. 2, four intake holes 6 are formed in an arc around the center of the frying cylinder 2 and communicate with the inside of the net-shaped sorting cylinder 3. The mesh net 6a through which the particles cannot pass is stretched and configured.

[0007] Therefore, while the cereals are lifted by the fryer 2, small cereals, dust and the like are removed from the reticulated sorter 3 and sorted, and the refined particles are lifted into the storage tank 8 by the discharge blades 4. in the state to release to, Ri by the suction dust-exhaust machine B
Negative pressure that by the suction air is in mesh screened cylinder 3 caused, the upper end face 5
The air is sucked from each of the suction holes 6 and flows from the inside of the mesh-like sorting cylinder 3 to the inside of the sorting chamber a. The elimination of small grains and the like can be effectively promoted, and the small grains fall to the collection stage 11 to be collected, and the dust and the like are sucked and sucked by the suction duster B through the communication hole 12 and discharged outside the machine. .

[0008]

As described above, according to the present invention, the upper end surface 5
Each intake consists holes 6 allow air to mesh screened cylinder 3, negative in mesh screening cylinder 3 caused Ri by the lower suction clean room machine
Supposed to that by the pressure suction air acts sufficiently within the mesh screening cylinder 3, will be able to effectively promote the elimination of dust and small grains such as passing the mesh screening cylinder 3, selected resistant Can be further improved, and the intake holes 6
Has a feature that the position can be suitably set or the net 6a can be stretched so as not to leak the grains, so that it can be suitably implemented.
