Abstract

PURPOSE:To prevent deterioration of durability by providing the sorting projections on a sorting plate and providing the ultrasonic wave emitting devices for emitting ultrasonic wave toward the steep tilt sides of the right and left directions of the sorting plate. CONSTITUTION:The blended grains consisting of unpolished rice and unhulled rice are supplied to the feed side of a sorting plate 1 and ultrasonic wave is emitted from the ultrasonic wave emitting devices 3, 3.... Thereby ultrasonic wave is allowed to act on the grains of a lower layer and supplied to the slow tilt face parts 2b side adjacent to the steep tilt face parts 2a side of the sorting projections 2, 2... from these steep tilt face parts 2a. Therefor unpolished rice is sunk to the lower layer and unhulled rice is raised to an upper layer. Then unpolished rice is successively moved and drifted to the steep tilt sides of the right and left directions and unhulled rice is drifted to the slow tilt sides of the right and left directions because of both reaction of movement of unpolished rice toward the steep tilt sides of the right and left directions and the tilt of the sorting plate 1 to the right and left directions. Thereby such a state that the unseparated blended rice is positioned in the medium thereof is obtained. Vibration is reduced and durability is improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a grain 1'17 sorting device i'i that uses Nil io waves, and is suitable for sorting mixed rice such as paddy and brown rice. It is available.

[Prior art and problems to be solved by the invention] Rocking
There is a swing-type sorting device that sorts paddy, brown rice, and mixed rice using a sorting board.

However, this oscillating sorting device has a problem in that it vibrates heavily and has poor durability. This invention solves these drawbacks by using ultrasound! This is what I'm trying to do.

[Means to solve the problem]

The technical means of the present invention for solving this technical problem is as follows: (The sorting plate 1 fixedly supported by the smoke body is tilted in the front and back direction so that the supply side is high and the discharge side is low, and The sorting plate 1 has a large number of sorting protrusions 2, 2, which are inclined so that one side is high and the other side is low.
The ultrasonic wave generator is characterized by being equipped with an ultrasonic transmitter 3゜3, . This is the structure of the grain sorting device used.

[Operation and effect of the invention]

d grains of paddy/brown rice are fed to the supply side of the sorting plate 1.

, . . . sorting protrusions 2,2. ...
The lower grains are transferred +11. Then, during the next stage of development, brown rice sinks to the bottom layer due to grain shape or specific gravity.
Paddy rice floats in the L-layer. Next, as a one-blow phenomenon,
The brown rice moves horizontally to the iI'li inclined side and drifts, and the reaction of this movement of the brown rice to the horizontally high inclined side and the sorting plate 1 is tilted in the left-right direction fIli. As a result, the unhulled rice drifts to the lower slope side in the left-right direction, and the mixed rice that has not been Alted is located in the middle.

Next, as the brown rice in the lower layer is moved by ultra-t'f waves and the sorting plate 1 is tilted in the front-back direction, the brown rice, mixed rice, and unhulled rice are sorted and purified one after another while moving toward the discharge side. 3 types of rice, brown rice, dL combined rice and unhulled rice
Selected in ICI.

It is taken out from the sorting plate 1.

In this way, the sorting plate 1 is fixedly attached to the aircraft body, and the mixed rice is super? Since the sorting is performed while being moved by the f-wave, vibration can be reduced and durability can be improved compared to the conventional device in which the sorting plate is shaken 1υj.

〔Example〕

First, the embodiment shown in FIGS. 1 to 3 will be described.

Reference numeral 1 denotes a sorting plate that is fixedly attached to the machine body. This sorting plate 1 has a quadrilateral planar shape, and is tilted forward and backward so that the supply side is high and the discharge side is low. The structure is also tilted so that one side is higher and the other side is lower. On the surface of the sorting plate 1, there are sorting protrusions 2, 2. ...is formed in large numbers. Then, the steeply inclined surface portion 2a of the sorting protrusion 2 is directed to the high inclined side in the left and right direction of the sorting plate 1, or to both the high inclined side in the left and right direction (ff) and the low inclined side in the front and back direction. An ultrasonic transmitter 3 is provided on the back side of the steeply inclined surface part 2a of the sorting protrusion 2, and the ultrasonic wave transmitter 3 is provided on the back side of the steeply inclined surface part 2a of the sorting protrusion 2, and the ultrasonic wave transmitter 3 is installed in a state where the ultrasonic wave transmitter It is configured to emit sound waves (11).

Also, although one drawing is omitted,
Oblique angle and left/right direction (111 oblique angle is R, ζLQ)
It has a structure that allows adjustment of the slope. Further, in this embodiment, the selection protrusion 2 is configured, but the selection protrusion 2 may be replaced with a selection recess. Further, the ultrasonic wave transmission direction of the ultrasonic wave transmitter 3 is set to i! 5Iillii may be configured.

! ``Part 1, 5 is a 1iIf fallen rice wind sorting section that wind-sorts the fallen rice from the defecation/7 section 4, 6 is a mixed rice lifting machine that supplies the fallen rice to the sorting plate 1, and 7 is a 1 is a rice frying machine which takes out the brown rice sorted by the sorting board 1, and 8 is a rice unhulling machine which returns the unhulled rice sorted by the 11th nozzle 1 to the dehulling section 4. be.

Since it is configured like a double series, mixed grains consisting of brown rice and unhulled rice are supplied to the supply side of the sorting plate 1, and the ultrasonic transmitter 3
,3. When a super wave is transmitted from 6, a super wave is sent to the lower grain. The ``τ wave acts, and the sorting protrusions 2, 2, etc. are sharply increased (moved 1 from the slope part 2a side to the gentle slope part 2b side of the adjacent sorting protrusion 2).

Then, as a second development, depending on the grain shape or specific gravity,
Brown rice sinks to the bottom layer, and unhulled rice sinks to the top layer. Then,
As a secondary phenomenon, the brown rice sequentially moves to the high slope side in the left and right direction and drifts, and the unhulled rice is tilted 11 in the left and right direction of the sorting plate 1 due to the reaction of the movement of the brown rice to the high slope side in the left and right direction. As a result, the rice flows to the side with a lower slope in the left-right direction, and the mixed rice that has not been separated is located in the middle. Next, the brown rice in the -do layer is moved by ultrasonic waves and the sorting plate 1 is tilted in the front-back direction, so that the brown rice is separated.

The mixed rice and unhulled rice flow toward the discharge side while increasing the sorting purity, and are sorted into three types: brown rice, mixed rice, and unhulled rice, and taken out.

In this way, the sorting plate 1 is fixedly attached to the machine body, and the mixed rice is sorted while being moved by ultrasonic waves, so shake the sorting plate! Compared to the conventional device of i+1+, vibration can be reduced and durability can be improved by 1-.

Next, other embodiments shown in FIGS. 4 to 6 will be described.
