Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a huller that removes culms from paddy in a huller mechanism, and then selects and extracts only brown rice from the grained rice after the deweighing. This invention relates to a sorting device.

[Conventional technology]

Japanese Utility Model Application Publication No. 57-12279 as a prior art discloses a hulling mechanism with a paddy supply hopper, a rotary sorting mechanism in which a brown rice catcher is provided in a rotating sorting cylinder with a large number of depressions on the inner peripheral surface. In a hulling sorting device in which the sorting cylinders in the rotary sorting mechanism are arranged in parallel so that the discharge side at one end is adjacent to the hulling mechanism, A plurality of paddy scooping blades are provided at appropriate intervals in the circumferential direction, and between the inside of the discharge side of the sorting cylinder and the paddy supply hopper, the paddy scooped up by the paddy scooping blades is transferred to the paddy supply hopper. By arranging a paddy returning chute for returning paddy to the hulling mechanism, the structure of the reducing mechanism for returning paddy discharged from the discharge side of the sorting cylinder in the rotary sorting mechanism to the hulling mechanism is simplified and lightened. It is proposed that the following measures be taken.

[Problem that the invention seeks to solve]

However, the hulling and sorting device described in the prior art uses a hulling mechanism for transferring and supplying the grained rice that has been deframed by the hulling mechanism to the supply side of the other end of the sorting cylinder in the rotary sorting mechanism. Since the dropped rice transfer means is disposed outside the sorting cylinder, the hulling and sorting device becomes larger by the size of the dropped rice transfer means.

In addition, as mentioned above, "a rotary sorting mechanism in which a brown rice catcher is installed inside a rotating sorting cylinder with a large number of depressions on the inner circumferential surface"
The dropped rice supplied to the supply side at the other end of the sorting cylinder is scraped up to a height created by the rotation of the sorting cylinder, and then falls, repeating the flow toward the discharge side at one end. While moving, 1g of brown rice in the fallen rice falls into a depression by 11χ and is lifted up to a high position and falls, while the paddy in the fallen rice falls from a lower position than the brown rice. Since the brown rice that falls from a high position is caught in the brown rice receiving gutter and taken out using the machine, the fallen rice flowing in the sorting cylinder is included as the sorting of brown rice progresses. The ratio of paddy increases (it shows the direction of the river).

As a result, the paddy is
This increases the frequency of brown rice entering the hollow and prevents the whole 11x of brown rice from entering the hollow, so the number of paddy entering the brown rice receiving trough increases, the sorting Rf degree of brown rice decreases, and the number of brown rice entering the brown rice receiving trough increases. As the amount decreases, the ability to sort brown rice decreases.

The present invention aims to solve this problem.

[Means to solve the problem]

In order to achieve this object, the present invention comprises a hulling mechanism with a paddy supply hopper and a rotary sorting mechanism in which a brown rice receiving trough is provided in a rotating sorting cylinder with a large number of depressions on the inner peripheral surface. The discharge side at one end of the sorting cylinder in the rotary sorting mechanism is arranged in parallel so as to be adjacent to the hulling mechanism, while the inner circumferential surface of the discharge side of the sorting cylinder is provided with a paddy scooping blade in the circumferential direction. A plurality of paddy blades are provided at appropriate intervals, and a paddy return chute is provided between the inside of the discharge side of the sorting cylinder and the paddy supply hopper for returning the paddy scooped up by the scooping blade to the paddy supply hopper. In the hulling sorting machine, the rotary sorting mechanism has a sorting cylinder in which a part of the sorting cylinder on the side of scraping up the fallen rice with respect to the brown rice receiving trough is provided with the hulling mechanism. A top-open circulation gutter that is equipped with a scraped rice transfer means for transferring the scraped rice after deframing from the discharge side at one end of the sorting cylinder to the supply side at the other end, and also used for supplying and transporting the scraped rice. On the other hand, the paddy side source chute is provided with a cover slanted diagonally downward to prevent the paddy scooped up by the scooping blade from entering the 1FIi ring gutter. It is.

[Action/effect of the invention]

In this way, the dropped rice is supplied inside the sorting cylinder at the other end of the sorting cylinder to the part on the side where the fallen rice is scraped up in the sorting cylinder with respect to the brown rice receiving gutter in the sorting cylinder of the rotary sorting mechanism. By installing an open-top circulation gutter equipped with a transfer means for transferring the rice to the side, as the sorting cylinder rotates, the unpolished rice that fits into the recess on its inner surface and is lifted to a relatively high position can be removed. , goes into both the brown rice receiving gutter and the circulation gutter, but the circulation gutter 5
Since it is located on the side that scrapes up the fallen rice in the sorting cylinder rather than the brown rice receiving gutter, a small amount of paddy enters the circulation gutter together with brown rice, but the proportion of paddy is smaller than that of the one-blade scraping mechanism. Since the ratio of unhulled rice is lower than the paddy ratio in the unhulled rice after deframing, the unhulled rice with a low unhulled ratio that enters this circulation gutter is supplied to the supply side of the sorting cylinder, thereby causing it to flow inside the sorting cylinder. The ratio of paddy in the rice that has fallen through the cracks is lowered, and the frequency of paddy that fits into the hollows decreases, while the number of hollows in which brown rice settles increases, which improves the accuracy of sorting brown rice and It is possible to improve the sorting ability.

On the other hand, as the fallen rice flows through the sorting cylinder and moves to the discharge side, the ratio of paddy becomes thicker as it approaches the discharge side, and on the discharge side, it becomes almost only paddy, and as the sorting cylinder rotates, After being scooped up to a high position by multiple scooping blades installed on the inner circumferential surface of the discharge side, the paddy is returned to the paddy supply hopper of the hulling mechanism via the paddy return chute and dehulled again. .

When the paddy is scooped up by the scooping blade, the paddy that falls off due to the force of the scooping blade enters the open-top circulation line, and the ratio of dropped rice to the paddy in the circulation line becomes high. Therefore, the effect of the circulation line is diminished.

In contrast, in the present invention, a cover for preventing the paddy scooped up by the scooping blade from entering the circulation gutter is provided on the single paddy chute in a diagonally downward direction from the paddy return chute. This cover can reliably prevent paddy spilling from the scooping blade from entering the circulation line during the process of scooping up the paddy by the scooping blade.

That is, according to the present invention, when the circulation line is provided in the sorting cylinder, when the paddy after sorting is returned to the hulling mechanism by the plurality of scooping blades provided on the inner peripheral surface of the sorting cylinder, one of the Since it is possible to reliably prevent the effect of the circulation line from being diminished due to the paddy entering the circulation line on the way, it is possible to improve both the brown rice sorting accuracy and the brown rice sorting ability in the hulling and sorting device. be.

Moreover, the present invention provides a scraped rice transfer means in the circulation gutter for transferring the scraped rice after dehulling by the hulling mechanism from the discharge side of the sorting cylinder to the supply side, and the circulation line is By configuring it to be used for both supply and transfer of scraped rice, the means for supplying and transferring the scraped rice after dehulling into the sorting cylinder can be built into the sorting cylinder, making the entire hulling and sorting device compact. It also has the effect of converting

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, reference numeral a indicates a hulling mechanism with a paddy supply hopper a', b indicates a wind selection section, and C indicates a rotary sorting mechanism, and the hulling mechanism a
and the rotary sorting mechanism C are arranged in parallel on the upper surface of the wind sorting section.

Reference numeral 1 in the figure indicates a horizontal sorting cylinder having a large number of depressions 2 on its inner circumferential surface and rotatably supported at both ends by drive wheels 3.4. One end farther from the mechanism a is configured on the supply side X, and the other end closer to the hulling mechanism a is configured on the discharge side Y.

Reference numerals 5 and 6 indicate a top-open circulation line installed in the sorting cylinder 1 from the supply side X to the discharge side Y, and a top-open brown rice receiving trough, respectively. for,
A spiral conveyor 7 for transporting the fallen rice entering this from the discharge side Y toward the supply side X and then supplying it from the drop opening 9 at one end to the supply side X in the sorting cylinder l is also connected to a brown rice receiver. Inside the gutter 5, a spiral conveyor 8 is installed in each gutter 5 to transport the brown rice contained therein from the supply side X to the discharge side Y. Also, one end of the discharge side Y of the circulation line 5 The tip of a scraped rice thrower 20 for transferring the scraped rice that has been deframed by the hulling mechanism a and then wind-selected by the winnowing unit is communicated with the part, and further, One part of the discharge side Y of the brown rice receiving trough 6 communicates with the brown rice removal chute 21.

On the inner peripheral surface of the sorting cylinder 1 on the discharge side Y, a plurality of (1j) blades 10 are provided at appropriate intervals in the circumferential direction. An annular weir plate 11 is provided to prevent the flow.

Further, reference numeral 12 in the figure indicates a paddy supply hopper a' in the VJ sliding mechanism a, which is used to collect the paddy scooped up by the scooping blade 10.
The paddy reducing chute 12 is composed of a bottom 13 and left and right side plates 18 and 19 that are slanted downward toward the paddy supply hopper a'. It communicates with the paddy supply hopper a' through an opening 17 provided in the wall plate 1G.The upper end of the other side plate 19 of the left and right side plates 18 and 19 and the scooping blade 1
0 is configured to be wider than the gap M between the upper end of one side plate 18 and the scooping blade 10, and in some cases, the other side plate 19 may be omitted as shown in FIG. . In addition, the bottom plate 13 has a dimension in which, with respect to a vertical line 0 passing through the center of the sorting cylinder 1, 1 width β on the upper side in the rotation direction of the sorting cylinder 1 is shorter than the width on the lower side in the rotation direction. It is composed of

The scooping blade 1 is provided in the paddy return chute 12.
I'll watch as the paddy scooped up at 0 enters the circulation gutter 5.
A cover 14 for stopping is provided diagonally downward from the paddy return shoe l-12. Note that the reference numeral 15 is a cover for the brown rice receiving trough 6.

Thus, the paddy supplied to the paddy supply hopper a' is dehulled by the hulling mechanism a, and then windscreened by the windscreening section so that the chaff is removed. The fallen rice after this air sorting is transferred to the discharge side Y in the circulation gutter 5 in the sorting cylinder 1 by the fallen rice thrower 20.
After being transported in the direction of the supply side X by the spiral conveyor 7 in the circulation gutter 5, it is supplied to the supply side X in the sorting cylinder 1.

The fallen rice supplied into the sorting cylinder 1 in this way is scraped up to the height determined by the rotation of the sorting cylinder 1 in the direction of arrow A, and then falls down repeatedly as shown in arrow 1. Move toward the discharge side Y. During this process, the brown rice in the sliding rice falls into the recess 2 and falls from a high position, thereby entering both the circulation gutter 5 and the brown rice receiving gutter 6.

In this case, since the circulation gutter 5 is located on the side where the fallen rice is scraped off in the sorting cylinder, the young paddy along with brown rice enters the circulation gutter 5, but the brown rice receiving gutter 6 contains Only brown rice enters the brown rice receiving trough 6, and after being transferred by the spiral conveyor 8, it is taken out of the machine from the brown rice take-out shoe 1-21. The brown rice that has entered the circulation gutter 5 is returned to the supply side in the sorting cylinder 1 together with the fallen rice, so that
The ratio of dropped rice to paddy inside the sorting cylinder 1 can be reduced.

On the other hand, the dropped rice that moves to the discharge side Y while flowing inside the sorting cylinder 1 has a higher paddy ratio as it approaches the discharge side Y.
On the discharge side Y, there is almost only paddy, which is scooped out by the scooping blade 10 and returned to the paddy supply hopper a' in the hulling mechanism a through the paddy return chute 12, where it is dehulled again. During the scooping of the paddy by the scooping blade XO, the paddy that falls from the scooping blade IO is collected from the top surface of the cover 15, which is inclined diagonally downward from the yJi 12 source 2-+-12, to the sorting cylinder 1. at the inner bottom of
Since the paddy is lowered, it is possible to prevent paddy particles falling from the scooping blades 10 from entering the circulation gutter 5.
