Description

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

BACKGROUND ART Conventionally, this type of device detects the layer thickness of grains supplied to the starting end of a rotary sorting tube, uses this detection to adjust the amount of paddy to be supplied to a husking device, The thickness of the inner grain layer was kept almost constant.

Problems to be Solved by the Invention A grain type in the form of a sorting cylinder that removes the supplied paddy using a husking device, mixes the husked brown rice with the husks, receives the husked rice, and sorts it while rotating. In the sorting device, a grain layer is formed in the sorting cylinder by the supplied grains, and an upward sorting process in which the grains are scooped up by a recess while being transferred and a downward process in which they fall are repeated. Sorting is done while This increase or decrease in the supply amount causes fluctuations in the grain layer in the sorting cylinder, which tends to have a negative impact on sorting performance, and may also change the type of grain supplied during operation or change the state of husking. If the amount of brown rice scooped up by the concave portion decreases, the amount of reduced rice circulating in the sorting cylinder will increase, and as a result, more brown rice will be mixed into the paddy that is sorted to be returned to the husking device. This tends to increase the number of damaged grains due to double rubbing, etc., and adversely affect the sorting accuracy.

Means for Solving the Problems This invention provides a sorting tube (2) which has a concavity (1) in its inner peripheral surface into which grains can fit, and which sorts the grains by rotation. A sensing valve (3) is provided on the (a) side and is movable up and down depending on the thickness and thinness of the supplied grain layer in the sorting tube (2), and a paddy is supplied to the husking device (4). The sensing valve (3) is connected to the paddy supply control valve (5) to automatically adjust the increase or decrease within a set range.
A return valve that receives the upper part of the grains descending from the ascending sorting stage to the descending stage, and returns the inner periphery of the sorting cylinder (2) from the vicinity to the end of the transfer to the lower end of the grain accumulation layer. 6)
is rotatably provided, and when the grain layer flowing down the upper surface of the return valve (6) exceeds a predetermined value, the grain layer detection reference position of the sensing valve (3) is moved to the thin layer detection side. This is the structure of the grain sorting device of the rice huller.

Functions and Effects of the Invention In order to rotate the sorting tube (2) to sort grains, the scraped rice scraped out by the husking device (4) is placed in the starting end of the sorting tube (2). The fed grains form an appropriate grain layer required for sorting on the inner peripheral surface of the sorting cylinder (2) and rise one rotation (
On the (a) side, the grains are transferred while repeating the sorting action of the upward sorting process where they are scooped up by the recess (1) and the downward process where some of the grains fall. Sorting is performed while the upper layer is received by the return valve (6) and returned to the lower end of the grain accumulation layer.

If there is a change in the amount of grains fed into the starting end of the sorting tube (2) during this operation, the layer thickness of the amount of grains formed in the sorting tube (2) will also change. The sensing valve (3) rotates up and down depending on the thickness of the grain layer, and the paddy supply control valve (5)
The sorting tube (2) is automatically adjusted to increase or decrease within the set range.
The reduction valve ( 6)
When the grain layer flowing down the upper surface exceeds a predetermined value, the reducing valve (6) rotates downward, and in conjunction with this rotation, the sensing valve (6) rotates downward.
3) is rotated downward to move the grain layer detection reference position to the thin layer detection side, the same effect as above is activated, and the grain layer necessary for responding to condition changes and sorting is obtained. Stable work can be performed without an increase in damaged grains due to scratching, etc.

(21)... is continuously supplied from the supply gutter (30) into the starting end of the rotating sorting tube (2).

The supplied grains in the sorting tube (2) form a grain layer from the tube end wall (22) side, and the sensing valve (
The paddy supply control valve (5), which is interlocked with the paddy feed control valve (3), operates to form the grain layer thickness necessary for sorting, and the rice grains are removed by the concave (1) on the rotating upward side (a) of the sorting tube (2). While repeating the sorting action of the upward sorting process of scooping up and the downward process of falling, the grains are transferred to the terminal side, and the upper part of the grains descending from this upward sorting process to the downward process is received by the return valve (6), Grains with a relatively high ratio of brown rice are sorted while being returned to the lower end of the grain accumulation layer, and the brown rice that is scooped out by the depression (1) falls into the brown rice receiving trough (24) and is sent to the helix (2B). The brown rice is transferred through the brown rice discharge passageway (37), a downstream shelf, etc., and then collected in the brown rice gutter (3rd day), and is carried out of the machine by the brown rice station TFF7-(39).

In addition, the mixed rice for reduction generated during the sorting process is transferred to the supply gutter (2).
7) The rice falls into the container, joins with the supplied crushed rice, and is supplied into the starting end of the sorting tube (2), where the sorting process is repeated again.

In addition, unhulled paddy is sorted and transferred to the terminal side of the sorting tube (2) while sliding down the surface layer of the flowing grain layer.
The paddy is pumped up in the pumping room (23) (23), transferred to the paddy return gutter (40), and returned to the paddy funnel (7) for reprocessing before the hulling work is performed.

If the amount of grains fed into one sorting tube (2) changes during this hulling operation, the thickness of the grain layer formed in the sorting tube (2) also changes. Due to this fluctuation, the sensing valve (3) rotates up and down within the set range, and in conjunction with this rotation, the opening degree of the paddy supply control valve (5) that supplies paddy to the husking device (4) increases and decreases. The amount of paddy supplied by rotating is automatically adjusted to decrease or increase, and grains that are balanced with the sorting throughput of the sorting tube (2) are supplied, resulting in stable sorting work.

Also, if the type of grain changes during the operation, or due to a change in the state of threshing or efficiency, the position of the grains rising and falling within the sorting tube (2) changes, causing them to flow down the top surface of the return valve (6). When the grain layer reaches a predetermined level or more, the return valve (6) rotates downward, and in conjunction with this rotation, the actuating plate (41) moves to the fulcrum pin (42).
The connecting plate (44) and the interlocking rod (52
), the sensing valve (3) is rotated downward to move the grain layer detection reference position to the thin layer detection side, and the same effect as described above is activated, and the grain layer detection reference position is moved to the thin layer detection side. A grain layer is obtained, and an increase in damaged grains due to double rubbing etc. can be prevented.
