Description

[Detailed description of the invention] Regarding.

In other words, the mixed rice after hulling can be well sorted by the rotating sorting cylinder, and the brown rice remaining in the paddy can be roughly and reliably separated at the end of the rotating sorting cylinder. , it can prevent so-called double shearing of brown rice,
It is provided that the structure is simple and can be conveniently implemented.

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

Figure 1 shows a general plan view of the entire huller sorting machine, with the huller section (a) on the side of one end of the long J wind sorting box (D) and the rotary grain sorting device (on the upper side of the other side). g) respectively.

Consists of.

It is constructed by installing both primary and secondary (b) transfer sorting cylinders (A) fa) above and below the inside of a 118tJ co-rotating grain sorting device (E) il-j: (of the case). The lower part of the projecting part formed protruding from one end of the upper part of the case @ is connected to the supply tank (5) so as to connect and communicate with one end port (7) of the supply gutter (6), It is constructed by installing the upper end of the mixed rice thrower 1 in communication with a tank installed at the other end of the upper part of the case.

The primary rotary sorting cylinder (A) in the upper part has supply sides (
It is formed into a cylindrical shape so that the a) and discharge side (b) are open, and the inner peripheral surface from the end of the supply side (a) to the middle of approaching the discharge side (0) has a threshold large enough to fit brown rice. A large number of thick four parts (11) are formed, and a rope part (N) that allows only brown rice to leak out is formed in a certain length range near the discharge side (b).
2) is stretched, and a boss 1 folding arm 125 (supported by the arm 125) is installed in the center of the end of the discharge (in November), and the rotation is fixed by fitting into the boss I23! When the shaft is mounted on the metal wall 1 +28+ on both ends of the case t221 (C) there is a goo 1) on the outer end of the rotating shaft @.

In addition, the inner surface of the case and the guide support plate (44) are provided in the space below the rope section (2) in the primary rotating sorting cylinder (A) at the rear (on the discharge side of the secondary rotating sorting cylinder (a)). A downward falling gutter (2) is formed, and the falling gutter 115) of the wind sorting box (D) is located below the falling gutter (2), and the rotary sorting cylinder (a) A guide plate (45) is provided diagonally from the lower side of the discharge side of the conveyance receiving gutter fB) to the fall i-15) side, and the lower opening of the downward gutter (46) communicating with the terminal side of the conveyance receiving gutter fB) is rotated. A gutter (47) communicating with the terminal end side of the supply side of the sorting cylinder (a) (・→Transfer receiving gutter fb installed so as to look inward) is connected to the droplet path ge+ in the wind sorting box (D).
Installed so that Vrc is connected (consisting of ~).

Boolean at the end of the rotating shaft (38) - (4B
+ and above)-17- (3G+ is connected to bell l-+49), and is installed so that it can transmit power from the lower gear box (5Q) to the belt pulley (51).

Inner rotating sorting cylinder fA) (a) A feeding blade for transporting grains in the axial direction is attached to the inner circumferential surface of the cylinder (a), but is not shown.

When paddy is supplied to the supply cook (5) during operation, both of the dehusking rolls (lil) in the dehusking section (4) climb up to 81 and escape. When the rice is fed into the conveyor (14), it is thrown up by the mixed rice thrower 1dol into the tank 124) and is supplied from the delivery gutter into the primary rotating sorting cylinder (A).

Then, as shown by the arrow (E) in Fig. 4, the brown rice is engaged with the four parts (1) of the rotary sorting cylinder (A), which rotates, and is lifted upward, and the end of the gate valve (3G) The brown rice passing through the conveyor receiving gutter (
B) A person falls into the rice field, and either the paddy is not picked up, or even if it is picked up, it is blocked by the partition plate j31i] and is about to fall, or it is sent in the direction of the arrow (G). When the paddy reaches a part (2), part (2) of the brown rice remaining in the first stage leaks out and falls into the drop-F gutter (3), and the paddy that is completely sent out from the discharge side (b) goes to the soil opening ( It falls into the supply gutter (6) from the 7th hole, and the shredded water is again supplied to the dehulling section (4).

On the other hand, the brown rice, etc. that have fallen into the conveyor receiving gutter (B) are sent in the direction of the arrow (example) by the spiral conveyor C34) to the gutter (46).
is fed into the secondary rotary sorting cylinder (a,), where it is
The mixed rice is sorted and sorted in the same way again, and flows out through the arrow (as shown by the single sword to the discharge side) and joins the brown rice from the falling gutter (3), and is transferred from the falling path L151 to the mixed rice conveyor. After falling into the rice field, the mixed rice thrower (4) jumps back into the tank (24) and is re-sorted.

The brown rice that has fallen into the conveyor receiving gutter (fb) is transferred to the spiral conveyor (4).
1), the person is transported in the direction of the arrow (N), passes through the gutter (47) to the brown rice conveyor (17), and is carried out of the machine by the brown rice thrower (21). 1 will be collected.

In this way, in the present invention, a transport receiving gutter (B) for receiving and transporting brown rice is installed inside the rotary sorting cylinder (A) in which a number of recesses (1) of a size large enough to fit brown rice are formed. However, the peripheral surface portion VC of the rotary sorting cylinder (A) that approaches the discharge 11111 (b) on the side opposite to the grain supply side (a) is a part (2) from which only brown rice can leak out. Since it is installed, when the mixed rice after hulling is being fed to the rotary sorting cylinder (A),
Transport the brown rice so that it is caught in the recess (1)
) can be separated and sent out for good sorting, and
At the end of the rotary sorting cylinder (A) (in 1411, the brown rice skein part (2) that remains in the beginning and is shredded can ensure reliable sorting and separation, and the rice can be sent from the rotary sorting cylinder (A) to the hulling side. It is possible to prevent brown rice from being mixed into the paddy and the so-called 21v sifting is performed, and it is preferable to have a simple structure in which the part (2) is integrally formed with one rotary sorting cylinder (A). It has the feature that it can be implemented.
