Description

[Detailed explanation of the idea] The present invention relates to a rotary grain sorter.

In other words, in a rotary grain sorting machine that is constructed by inserting a receiving gutter into a rotatably horizontal sorting cylinder that has multiple recesses on its inner circumferential surface that are large enough to fit brown rice, it is possible to The combination of a rotary grain sorter consisting of a large-diameter sorting tube and a small-diameter sorting tube makes it easy to assemble into the machine, easy to disassemble, and facilitate cleaning and inspection, while being compact. It is an object of the present invention to provide a rotary grain sorter that can exhibit its sorting ability and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the rice hulling sorting device, in which a hulling section E is mounted above the front side of a long wind sorting box, and a rotary grain sorting machine C is mounted above the rear side. Configure.

This wind sorting box is equipped with a mixed rice conveyor 3, a paddy conveyor 4, a brown rice conveyor 5, etc., which are connected to the suction dust extractor 2 at the front. A rice thrower 6, a paddy thrower 7, and a brown rice thrower 8 are installed in series, and the upper part of the paddy thrower 7 is communicated with a hopper 10 above the hulling section E having a pair of demixing rolls 9. It is configured so that the power is transmitted to each part from a motor M inside the rear side of the wind selection box.

The rotary grain sorter C is constructed by combining a rotary grain sorter consisting of a large-diameter sorting tube A and a small-diameter sorting tube a in the machine body 11. A large number of recesses 1 are formed on the inner circumferential surface, and both sides of the front and rear are open, and a rotating shaft 12.12 is provided on the lower side of the front and rear.
Two rollers 13.13 driven by rollers 13.13 are connected to each other, and the sorting tube A is supported by the rollers 13.13 and rotatably mounted horizontally, and presser rollers 14. 14 is joined.

In the lower part of this sorting tube A, a ■-shaped receiving gutter B that is supported from the fuselage 11 side is inserted and positioned horizontally, and the upper part of one side of the receiving gutter B is positioned close to the inner circumferential surface of the sorting tube A. A spiral conveyor 17 rotated by a rotating shaft 16 is installed at the lower center of the receiving gutter B.

Inside the sorting tube A, a small-diameter sorting tube a having the same structure as the sorting tube A is installed above the receiving gutter B, and a receiving gutter that is supported from the body 11 side is inserted into the sorting tube a as well. At the same time, an adjustment plate 15 is connected to the upper part of the other side, a spiral conveyor 17' driven by a rotating shaft 18 is installed at the lower center of the receiving gutter, and the base of an arm 19 connected to the rear part of the sorting tube a is installed. It is fixed to the rotating shaft 18 and supported by a support roller 20 joined to the front part.

The mixed rice thrower is attached to the rear upper part of the machine body 11.
Supply tank 2 that receives the mixed rice thrown up by 6
The lower opening of the sorting tube A is connected to the rear side of the sorting tube A, and the front side of the sorting tube A is installed so as to communicate with the paddy conveyor 4 side. 2
The lower opening of the intermediate tank 23 which receives the brown rice etc. thrown up by step 2 is connected to the front side of the sorting tube a, and the rear side of the sorting tube a is installed so as to look into the rear side of the sorting tube A. The lower opening of the gutter 24 communicating with the terminal end side of the spiral conveyor 17' is configured so as to communicate with the brown rice conveyor 5 side.

As shown in Figs. 3 to 5, both sorting cylinders A, a are divided parallel to the axis of rotation into two arc-shaped half cylinders A, A2 and a□, a2, respectively. configured to allow
In the large-diameter sorting tube A, there are rollers 13 on both the front and rear sides.
A half-cylindrical body A1.13 is joined with a flange 25.25 standing upright around the outside, and the half-cylindrical body A1. Flanges 26, 26 are formed on both sides of A2, which are joined to each other and can be attached and detached by bolts and nuts 28.

Further, the small-diameter sorting cylinder a has a flange 27 for joining to the roller 20 only on the front side, and flanges 29 and 29 are formed on both sides of the half-cylindrical bodies a1 and a2, which are joined to each other and can be attached and detached by bolts and nuts 28. Configure.

Therefore, both sorting tubes A, a have flange 26.2
6 and 29.29 respectively and bolt and nut 28.2
By tightening 8, the amphibious cylinder body A1. A,,, a
1 and A2 can be assembled or disassembled, and each can be disassembled to clean or inspect clogging, etc., and can be easily assembled.

Therefore, the mixed rice supplied from the mixed rice thrower 6 to the supply tank 21 is fed to the rear side of the sorting tube A, and while the mixed rice is in contact with the inner peripheral surface of the sorting tube A rotating in the direction of arrow A, Brown rice and some of the paddy fit into the recess 1 and are lifted upwards, and most of the paddy fits into the recess 1 and is lifted upwards.
Most of the paddy cannot fit into the recess 1 and slips down, and the brown rice and some of the paddy that are lifted upward fall out of the recess 1 and fall onto the spiral conveyor 17 in the receiving trough a. Most of the paddy that is not lifted by the paddy is moved inside the sorting tube A as shown by the arrow, falls onto the paddy conveyor 4, is thrown up into the hopper 10 by the paddy thrower 7, and is removed again.

Brown rice, etc., which falls into the spiral conveyor 17 and is transferred in the direction of the arrow, is thrown up by the thrower 22 into the intermediate tank 23, is fed as it is into the sorting tube a, and rotates as shown by arrow 2. The rice is sorted in the same manner as described above by the sorting tube A, and most of the brown rice falls into the spiral conveyor 17', and the paddy mixed with brown rice that cannot be lifted up by the recess 1 is sent in the direction of arrow H and returned to the sorting tube A again. The brown rice that has fallen into the spiral conveyor 17' is transferred in the direction of the arrow, and then falls from the gutter 24 to the brown rice conveyor 5, where it is taken out by the brown rice thrower 8.

In this way, the present invention has developed a rotary grain grain system, which consists of a sorting cylinder that has multiple recesses on its inner circumferential surface that are large enough to fit brown rice, and a receiving gutter that is inserted horizontally into the sorting cylinder that is horizontally suspended so that it can rotate. In the sorting machine, when a rotary grain sorter is constructed by combining a large-diameter sorting tube and a small-diameter sorting tube, a receiving gutter that is inserted horizontally into the large-diameter sorting tube is installed at the bottom of this sorting tube. It is located above the small diameter sorting tube and the receiving gutter inside this large diameter sorting tube,
In addition, since the large-diameter sorting tube is divided in the direction of the rotational axis, and the sorting tube can be divided into at least two parts, a rotary grain sorter consisting of a large-diameter sorting tube and a small-diameter sorting tube can be combined. In this case, a small-diameter sorting tube is housed inside a large-diameter sorting tube, but since the large-diameter sorting tube can be separated, it is easy to assemble the sorting tube into the body, and it can be easily disassembled. This sorting tube is easy to clean and inspect, and has a compact structure with a small diameter sorting tube inside the large diameter sorting tube. Since it is located at the bottom of the tube, a large space is formed inside the sorting tube above the receiving gutter, and small diameter sorting tubes can be set to the largest possible diameter, which makes it easier to sort small diameter sorting tubes. It has the advantage of dramatically improving abilities.
