Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain sorting device for a rice huller.

Problems to be Solved by the Invention A rotary sorting tube is provided with a helical receiving trough that has a concave part formed on its inner circumferential surface and a brown rice sorting valve in the center that receives and carries out the brown rice that is sorted through this concave part. In a huller that feeds and sorts grains, the grains fed into the sorting cylinder form a grain layer from the starting end side, and the grains are scooped out by the recessed part. The brown rice that falls from the raised position is received by a spiral receiving gutter and is sorted from reduced mixed rice, etc. However, the falling position of the grains may change depending on the type of grain being supplied, such as the size or small size of the grains. This causes an increase or decrease in the reduced mixed rice, and changes in the grain layer thickness inside the sorting tube due to this increase or decrease tend to have a negative effect on sorting accuracy and efficiency. It is easy to get clogged inside.

Means for Solving the Problem The present invention provides a sorting tube (2) in which a concavity (1) into which grains can fit is formed on the inner circumferential surface of the sorting tube (2) for sorting by rotation. A receiving gutter (3) is provided, and a brown rice sorting valve (4) is provided on the sorting cylinder (rotation rising (a) side) of this receiving gutter (3) so as to be movable up and down, and the starting end of the sorting cylinder (2) is supplied. The sensing valve 6), which moves downward by -L depending on the amount of grains, and the brown rice sorting valve (4) are interlocked and connected in such a relationship that the brown rice sorting valve (4) is moved downward when the sensing valve 6) detects an increase in the amount of grains. At the same time, between the paddy supply control valve (7), which is to supply paddy to the husking device S), and the sensing valve 6), the paddy supply control valve (7) decreases the amount of paddy supply by detecting an increase in the amount of paddy from the sensing valve 6). In conjunction with this relationship, a regulating device (8) is provided between the sensing valve 6), the paddy supply regulating valve (7), and the brown rice sorting valve (1) to change and adjust the relative position of the brown rice sorting valve 0. ) is the structure of the grain sorting device of the huller.

Functions and Effects of the Invention In order to sort the rice scraped out by the scraping device (6) with a rotating sorting tube, during steady operation, the scraped rice is transferred to the starting end of the sorting tube. When a certain grain layer is formed by feeding, this grain layer is deviated in the rotation direction of the sorting tube, and some of the grains fit into the recess (1) and are lifted up. The grains falling from the position are received by the brown rice sorting valve (4) and the helical receiving gutter (3), and the brown rice being transferred and carried out in the helical receiving gutter (3) and the grains remaining in the sorting tube (3) are separated. The grain layer thickness sensing valve 6 necessary for sorting is linked to the operating position of the sorting cylinder (inner brown rice sorting valve ■) and the position of the grain layer thickness sensing valve 6 necessary for sorting in an almost optimal state.
The brown rice sorting valve (4) rotates downward upon detection by the sorting tube (if the grain layer in the tube increases in amount further, the sensing valve 6) increases the amount of sorted into the helical receiving trough (3). At the same time, the paddy supply control valve (7) for supplying paddy to the husking device (6) is interlocked and adjusted to supply a reduced amount of paddy through the control device (8), and the grains in the sorting tube are If the amount decreases, the detection valve 6) rotates the brown rice sorting valve (4) upwards,

A grain layer is formed from the starting end wall (4) side of the supplied sorting cylinder (Rino's rolled rice), and depending on the thickness of this grain layer, the brown rice sorting valve 0 is interlocked and connected to the sensing valve 6, and the paddy supply. The control valve ■ operates to form the grain layer thickness necessary for sorting, and the sorting tube (2
The material is transferred to the terminal side while repeating the sorting action of the ascending sorting process in which it is scooped up by the concave (1) and the descending process in which it falls on the rotating upward (A) side of 1, and is scooped up by the concave (1). Brown rice falls into the helical receiving trough (3), is transferred by the helical (C), and is carried out of the machine by a brown rice thrower (G) through the discharge passage OQ.

The mixed rice for reduction, which is a mixture of brown rice and paddy generated during the sorting operation, falls into the supply gutter Q$, merges with the supplied washed rice, and is fed into the starting end of the sorting tube (2). Then, the sorting process is repeated again.

In addition, the unhulled paddy is transferred to the terminal end of the sorting tube (2) while sliding down the surface layer of the flowing grain layer, the above sorting is repeated, and it falls from the terminal end of the sorting tube (2). Then, the reduction hopper (to) of hopper (9) is used as a paddy thrower.
Steady operation work is performed while being reduced to and reprocessed in the depurifying roll 01) 01).

During this routine operation, the grain layer thickness of the grains fed into the starting end of the sorting tube (the sensing valve 6) is detected, and the sensing valve 6 detects changes in the grains to be fed. ) is rotated upward, the brown rice sorting valve (2) is interlocked with the link rod shaft and the adjustment weight and rotated downward to increase the amount of sorting to the helical receiving trough (3). The opening of the paddy supply control valve (2), which is interlocked via the operating rod, shaft (B), operating plate 04, etc., is adjusted to reduce the amount of rice supplied, and in the opposite direction to the above, the sensing valve 6) is rotated downward. For example, the brown rice sorting valve 0 rotates upward to reduce the amount of rice to be sorted into the helical receiving trough ■, and the opening of the paddy supply control valve ■ is adjusted to increase the amount of grain supplied to the grain layer thickness suitable for sorting. It is operated to maintain stable and steady operation work.

In addition, due to changes in the hulling conditions during the operation, such as changes in the type of paddy, changes in the rotation of the sorting tube, or changes in the hulling rate of the hulling device [F], the sorting tube ( If there is a change in the sorting state of the grains within z and the rising and falling position of the grains changes and you want to increase the sorting processing efficiency, grip the adjustment weight plate 0 and operate the adjustment lever (4). If the operating position of the brown rice sorting valve 0 is rotated downward, the amount of rice falling into the helical receiving trough ■ will increase, and the sensing valve 6) will be rotated upward once, thereby separating the sensing valve 6] and the grain layer. If a gap is created between the two, the weight of the adjustment weight plate 0 causes the sensing valve 6) to rotate downward, increasing the opening degree of the paddy supply control valve (2). Conversely, if you wish to lower the sorting processing efficiency, operate the adjustment lever in the same manner and rotate the operating position of the brown rice sorting valve (4) upwards to reduce the amount of water to the helical receiving trough (3). The falling amount decreases, and the sensing valve 6) is once rotated downward, whereby the sensing valve 6) is rotated upward under pressure from the grain layer, reducing the opening degree of the paddy supply control valve ■. By supplying grains, a grain layer necessary for responding to changes in conditions and for sorting can be obtained, and stable work can be performed without clogging in the sorting cylinder (21).
