Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to a sorting cylinder that has a number of depressions formed in its inner circumferential surface and is rotatably suspended horizontally. A plurality of jump plates are installed at equal intervals on the inner circumferential surface of the grain discharge side end of the sorting cylinder, and a grain removal gutter whose upper plate communicates with the outside of the machine is placed below the rotation path of the jump plate. A comparison is made in which the grains that are not scooped up into the receiving gutter and reach the discharge side end are lifted by the recesses formed on the inner circumference of the sorting cylinder, which are placed close to each other, and are lifted by a jump plate that rotates in unison with the sorting cylinder. This relates to a grain removal gutter that receives and takes out grains lifted by the jump plate in a system that supplies the grains from a high point to the next process.

[Conventional technology]

A receiving gutter is inserted horizontally into a sorting cylinder which has many depressions formed on its inner peripheral surface and is rotatably hung horizontally, and a plurality of jumps are installed on the inner peripheral surface of the grain discharge side of the sorting cylinder. A rotary sorting machine in which upper plates are mounted evenly and a grain removal gutter that communicates with the outside of the machine is provided close to the lower side of the rotation trajectory of the jump plate has been developed as a prior art. It is described in No. 57-12279.

[Problem that the invention seeks to solve]

However, in this prior art, the grain removal gutter for receiving the grains scooped up by the jump plate is shaped like an upward U-shape with guide plates on both left and right sides of the same height. Therefore, it is difficult for the grains scooped up by the jump board to enter the grain removal gutter, in other words, the efficiency of grain frying is low and the grains cannot be discharged smoothly.

The present invention aims to solve this problem.

[Means to solve the problem]

In order to achieve this object, the present invention has a number of depressions formed in the inner circumferential surface of the sorting cylinder, which is rotatably suspended horizontally, and in which a receiving gutter is inserted and horizontally suspended, and the grains of the sorting cylinder are A plurality of jump plates are installed at appropriate intervals in the circumferential direction on the inner circumferential surface of the discharge side end of the machine, and the grain removal gutter whose upper plate communicates with the outside of the machine is brought closer to the bottom of the rotation trajectory of the jump plate. In the grain removal device for a rotary sorting machine, the upper plate is deviated upward in the rotational direction of the sorting cylinder, and guide plates are erected on both sides of the upper plate. The upper edge of one guide plate on the upper side and the jump board! I! The gap with the JJ locus is smaller than the gap with the upper edge of the other guide plate.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. This embodiment shows a rotary sorting paddy In device combined with a rotary sorter equipped with a grain removal gutter according to the present invention.

A is a deframing section with a paddy supply hopper a', b is a wind sorting section, and C is a rotary sorting machine.The deframing section a and the rotary sorting machine C are installed before and after the wind sorting section.

Therefore, the description of the frame removal part a and the wind selection part will be omitted, and the explanation will be mainly given on the rotary selection part 14c.

Reference numeral 1 designates a sorting cylinder having a number of depressions 2 formed in its inner circumferential surface and horizontally suspending both front and rear ends thereof so that they can be rotated by driving wheels 3.4. The rotating axis of the body L is oriented in the front-rear direction, and the mixed grain supply side It is.

Reference numerals 5 and 6 denote a mixed grain transfer gutter and a brown rice receiving gutter which are horizontally suspended from the supply side X to the discharge side Y in the L sorting cylinder 1. screw conveyor 7
．． 8 is installed internally, and the mixed grain transfer gutter 5 opens a drop port 9 that transports the mixed grains from the discharge side Y to the supply side (11J 6 is configured to be transferred from the supply side X to the discharge side Y.

A plurality of jump plates 10 are attached to the inner peripheral surface of the discharge side Y end of the sorting cylinder 1 at appropriate intervals in the circumferential direction,
Reference numeral 11 denotes an annular blocking plate that is joined to the outside of this jump plate 10 and prevents the grains that have reached the discharge side Y from spilling out.

Reference numeral 12 designates a grain extraction gutter, which is formed into a substantially trapezoidal shape by an upper plate 13 that slopes forward and serves as a grain extraction surface, and side plates 14 and 15 that extend diagonally downward from both sides of the upper plate 13, respectively. The upper plate 13 is attached to the front wall 16 of the rotary sorting machine C so as to be close to the lower side of the rotation trajectory of the jump Fi 10 and to straddle the mixed grain receiving gutter 5 and the brown rice receiving gutter 6. It is worn,
An outlet 17 communicating with the outside of the machine is provided at the joint portion of the front wall I6 with the upper plate 13.

Therefore, as shown in FIG. 3, the upper plate 13 of the grain removal gutter 12 is located on the upper side in the rotation direction (indicated by arrow A) from the rotation axis 0 of the sorting cylinder l and on the opposite side. The guide plates 18° and 19 are erected by bending the ends of both sides upward, and the guide plates 1
8. Behind 19, one guide plate 18 on the upper side in the rotation direction
is set higher than the other guide plate 19 so that the gap M between the rotation locus of the jump plate 1o and the upper edge of one guide plate 18 is smaller than the gap N between the upper edge of the other guide plate 19. It is composed of:

Reference numeral 20 denotes a thrower 121 for lifting the mixed grains after unframed air sorting into the mixed grain transfer gutter 5, and a drop path for taking out the brown rice in the brown rice receiving gutter 6.

In addition, what is shown in FIG. 4 shows another embodiment of the grain removal gutter 12, and the guide plate 18 is installed upright on both sides of the upper plate 13.
．． Of the 19, only one guide plate 18 on the upper side in the rotating direction of the sorting cylinder 1 is configured, and the other guide plate 19 is omitted, and the gap M is smaller than the gap N.

Therefore, the mixed grains of brown rice and paddy after being deframed and air-sorted by the deframing section a and the wind sorting section are lifted up into the mixed grain transfer gutter 5 by the thrower 20, transferred toward the supply side X, and then dropped. The person falls from the opening 9 onto the inner peripheral surface of the sorting cylinder l.

The mixed grains that have fallen in this way gradually flow in the direction shown by the arrow in Figure 1 due to the scooping action of the depression 2 which rotates in the direction shown by arrow A in Figure 2. They are sorted out.

After pounding, the brown rice, which is smaller than paddy, is difficult to escape from the depression 2 and is scooped up to the highest level, forming a parabola and falling into the brown rice receiving trough 16, where it is separated from the brown rice that cannot be scooped up to the highest level. The remaining paddy falls into the mixed grain transfer gutter 15 and joins with new mixed grains, and the sorting action by the depression 2 is repeated again, and the unscooped paddy moves to the discharge side Y and is transferred to the jump plate 10.
The particles are lifted up and released, and mainly fall onto the upper plate 13 on the upper side in the rotational direction than the rotational axis 0 of the sorting cylinder 1, and are guided by the guide plate 18 and flow out forward, with some of them falling onto the guide plate 18. 18 and is guided forward and the outlet 1
7 and is returned to the unframed part a.

Furthermore, when being lifted up by the jumping board 10, the upper board 1
The paddy that does not reach the top of 3 descends along the side plate 14 and reaches the guide plate 1.
The paddy that has jumped over the upper edge of 8 falls along the side plate 15, and some of them fall onto the inner peripheral surface of the sorting cylinder 1, while others fall out of the sorting cylinder 1 from between it and the front wall 16. There are some things.

Then, the former paddy is lifted again by the jumping board IO,
The latter particles fall into the wind separation section and are lifted up again into the mixed grain transfer trough 5 by the thrower 20.

In addition, the brown rice that has flowed into the brown rice receiving trough 6 is discharged from the discharge side Y.
After passing through the drop path 21 and being screened, it is taken out to a suitable location outside the machine.

[Action/effect of the invention]

As described above, the present invention has a receiving gutter that is inserted into a sorting cylinder that is rotatably suspended horizontally by forming a large number of depressions on its inner circumferential surface, and the grain discharge side end of the sorting cylinder. Grain in a rotary sorting machine in which a plurality of jump plates are installed at equal intervals on the inner circumferential surface of the part, and a grain removal gutter whose upper slope communicates with the outside of the machine is provided close to the bottom of the rotation trajectory of the jump plate. In the take-out device, the upper plate is deviated upward in the rotational direction of the sorting cylinder, and guide plates are provided on both sides of the upper slope. Rotation of the jumping board! Since the gap with the l1IL mark is configured to be smaller than the gap with the upper edge of the other guide plate 19, the gap N between the upper edge of the other guide plate 19 and the rotation locus of the jump plate is relatively large. This allows the grains to be easily lifted onto the upper plate by the jump plate, and the grains lifted and discharged by the jump plate mainly fall on the upper side in the rotational direction of the rotation axis of the sorting cylinder. Since the upper slope is provided offset to the upper side, it is reliably collected by the upper plate, and the gap M between the upper edge of one of the guide plates on the upper side in the rotation direction and the jump plate is Because of their small size, grains that jump over the upper edge of this guide plate are extremely prevented, and the lifting efficiency of grains has been dramatically improved.
