Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a rotary sorting tube-type grain sorting device that sorts mixed grains such as paddy and brown rice using a rotary sorting tube having a large number of potholes on its inner circumferential surface. The rotating sorting tube is configured to be relatively long to improve sorting efficiency, and the grain gutter that receives the grains sorted by the rotating sorting tube is taken out by an inclined grain gutter, so that the sorted grain can be removed. To take out the grains,
The purpose is to simplify the configuration without requiring a special transfer device such as a spiral transfer device, and to reduce costs.

Embodiments of the invention shown in the drawings will be described below.

To explain the structure of the embodiment without shredding, (1) is a dehulling part, and this dehulling part (1) is connected to a paddy tank (2), a pair of dehulling rows/l' (3) (3) It is made up of etc.

(4) is a wind sorting section which sorts out the fallen rice from the under-hulling section (1) using the sorting wind generated by the suction machine (5) in front;
The rice husks are discharged from the suction machine (5) to the outside of the machine through the dust exhaust pipe (6), and the mixed rice of brown rice and paddy falls to the sliding rice receiving trough (7) below. ) is configured to be transported to a mixed rice supply hopper (9) by a mixed rice lifting machine (8).

00 is a sorting case, and inside the sorting case 01 there are provided a supply side end (on the left side in FIG. 1) and a rotary sorting cylinder 01 which has a large number of potholes on the inner circumferential surface so that it can rotate almost horizontally. Place the discharge side end (right side in Figure 1) on the drive roller α (
A) is rotatably supported.

In this rotary sorting cylinder 01), an inclined rice mallet 03 and an inclined mixing rice trough Q4) are arranged. This inclined finishing rice gutter 03 is inclined in two directions so that the longitudinal middle part of the rotary sorting cylinder 01) is located at the upper side, and the supply side end and the discharge side end of the rotary sorting cylinder 01) are located at the lower side. The lower end of the front side of this inclined finishing rice gutter 0 [exist] is the lower pipe of the pre-finishing rice stream 0.
υ and the pre-finishing rice flow lower plate 0O, the rotary sorting cylinder 01
) - Rice barley 1iiiI (17)
Furthermore, the rear inclined lower end of the inclined finishing rice trough α-jo communicates with the finished rice receiving trough 071 via the finishing rice flow lower tube 0 and the finishing rice flow lower plate 00. As shown in Fig. 2, this sloping finishing rice gutter 03 is installed horizontally in parallel with the slanted mixing rice trough Q4), and the slanted mixing rice trough Q4) corresponds to the discharge side portion of the rotating sorting cylinder α1). The rotary sorting cylinder θ1) is arranged on the side that rotates in one direction from below, and the inclined finishing rice gutter 03 is arranged on the side that rotates downward from above the rotating sorting cylinder 0η. The mixed grains of brown rice and paddy that have flowed down into the inclined rice mixing trough 04) are communicated to the dropped rice receiving trough (7) via the mixed rice flow down tube (a). Ql) is a mixed rice supply cylinder that supplies the mixed rice supplied to the mixed rice supply hopper (9) to the supply side end of the rotary sorting cylinder θη. In addition, the drive roller θ drive shaft (a)
Extend the shaft end from the sorting case 00 to the removal part (1) side, attach the pulley (c) to this extension, and still extend it from the removal part (1) to the sorting case 00 side. Attach a pulley handle to the power take-off shaft (c), and both booms! J-623,
(1 is transmitted through a belt (not shown). It is a rice grain lifting machine. There is a - side below the discharge end of the rotary sorting cylinder 01). The paddy flowing down from the discharge side end of the rotary sorting tube 0]) to the paddy receiving trough (A), forming an inclined paddy receiving trough (C), is transferred to the paddy tank (A) via the paddy lifting machine (C).
2).

Next, the operation of the embodiment will be explained. When carrying out the hulling operation, raw wire is supplied to the hulling tank (2), and each rotating part of the hulling machine is driven. Then, the paddy supplied from the paddy tank (2) to the de-weighing roll (3) (3) is subjected to the dehulling action. The mixed rice of brown rice and paddy is discharged from the machine from 6) and falls into the surori rice receiving trough (7), where it is lifted up by the surori rice grain lifter (8) to the mixed rice supply hopper (9). , the mixed rice flows from the mixed rice supply hopper (9) to the rotary sorting cylinder 0 via the lower cylinder Q◇)
is supplied to the supply end of the inside.

The mixed rice supplied to the supply side end of the rotating sorting cylinder 01) is
The fine brown rice is extracted through the pot hole of the rotary sorting cylinder 0) which is rotating clockwise in Figure 2, and the fine brown rice is passed through the inclined finishing rice trough a.
At the same time, the rice mixed with paddy and some brown rice falls into the inclined mixing rice trough Q→ and is sorted. The unsorted mixed rice that has fallen into the slanted rice mixing gutter Q4) flows down the gutter and is sent to the dropped rice receiving gutter (7) via the mixed rice supply pipe and is re-sorted. In addition, the finished rice that has fallen into the inclined finishing rice gutter α→ flows down along the front and rear sloped surfaces from the front-rear intermediate part of the inclined finishing rice gutter 03, and flows down from the front and back slopes of the inclined finishing rice gutter 03 to the previous rice flow lower cylinder OQ and the previous finished rice flow lower plate. 0 → and while falling through the lower cylinder 08) of the finishing rice stream and the lower plate 0 of the finishing rice stream, and falling into the finished rice receiving trough Q7), it is subjected to wind sorting action and is sent out of the machine by the finishing rice lifting machine (E). Served. In addition, a paddy receiving trough (
The paddy that has fallen into step (a) is returned to the paddy tank (2) of the unhulling section (1) by the unhulling machine (c), and is subjected to the unhulling action again.

As mentioned above, in this embodiment, the rotary sorting cylinder 01
) One machine 03 for receiving finished rice sorted by
Since the rotary sorting tube α1) is constructed with inclined surfaces in two directions, with the longitudinal middle part high and both front and rear ends low, the angle of inclination can be made steep, and the rotary sorting tube 0
]) can be configured to be relatively long in the axial direction, increasing the sorting efficiency. No special transfer device such as transfer device is required.
These driving devices can be omitted and the configuration can be simplified.

This invention provides a rotary sorting tube 01) having a large number of pot holes on its inner peripheral surface, and an inclined grain gutter (11) for receiving the grains sorted by the rotary sorting tube 01) in the axial direction of the rotary sorting tube αD. In installing the grain sorting device, the rotary sorting tube a→ of the inclined grain gutter 03 is inclined in two directions so that both end sides in the axial direction are positioned low and the middle side is positioned high. The inclination angle of the gutter 03 can be configured to be relatively steep, allowing grains to be taken out smoothly, and the inclined grain gutter 0
In order to take out the grains that have fallen in the third step, a special table transfer device such as a spiral transfer device is not required, and the structure is simple and costs can be reduced.
