Description

DETAILED DESCRIPTION OF THE INVENTION The present invention addresses the limits of the function of the sensing valve housed in the sensing cylinder that can interlock the sliding amount adjustment plate in the weighing section when the amount of rice sliding down in the weighing section is extremely large. In cases where foreign substances mixed in grains are exceeded, a detection casing is used to remove foreign substances from the machine from the end of the sorting action on the inner surface of the sorting cylinder, where it is easy to detect foreign substances mixed in the grains. By draining the excess fallen rice into this foreign matter removal tube and taking it out of the machine, clogging due to the fallen rice is prevented, which leads to malfunctions in the hulling and sorting action and, ultimately, to machine operation stoppage. This is an attempt to resolve the situation.

Hereinafter, referring to the drawings, (A) is a deweighing section, which consists of a paddy tank (1), a pair of deweighing rolls (2), etc., and (B) is a deweighing section, which is a wind sorting section. It is in charge of the wind selection of the fallen rice from (A) and the wind selection of the brown rice sorted in the rotary sorting section (0).

(3) is a suri-roki rice grain cylinder, and (4) is a brown rice grain lifter. The rotary sorting section (0) separates the scraped rice that has been wind-selected by the weighing section (A) and the wind sorting section (B) into brown rice and paddy, and these ), wind sorting section (B), rotary sorting section (C
) is constructed by placing a weighing part (A) on the front side of the wind sorting part (B) and a rotary sorting part (0) on the upper part of the rear part.

In the rotary sorting section (0), (5) and (6) are primary and secondary sorting cylinders with a large number of depressions (a) formed on the inner peripheral surface, which are arranged vertically and in a substantially horizontal state. The feed (1111

In parallel, a screw conveyor (7) for receiving and taking out the sorted material scooped up by the depression (a) is horizontally installed (with a built-in receiving trough), and the discharge side (Y) is used to carry out paddy harvesting (.).

You can get a peek at the top.

There is also a recess (a) horizontally installed in the secondary sorting cylinder (6) to receive the sorted materials scooped up by F, and 00.(11) ) provided in 1
The sorted materials received in the receiving gutter (8) in the next sorting cylinder (5) are
Secondary sorting cylinder (61K) Communication gutter for inflow, 1121 Circulation path that communicates the discharge side (Y) of the secondary sorting cylinder (6) with the fallen rice frying cylinder (3), (13) Receiving gutter (9) This is a channel for leading out the brown rice inside onto the flow plate (j4) of the wind sorting section (B).

(T) is a supply tank for dropped rice, which is attached to the side wall (151) on the upper side, that is, the discharge side (Y) of the culling part (A), and the lower part communicates with the starting end of the transfer device (b); At the top, there is an overflow port (16) for excess rice droplets, and a wall (171) adjacent to this overflow port 061 has a window fly+ with a transparent body (18) that can be inserted and removed at will.
Open the top plate (5) (into the top plate (5) and insert the tip of the sliding rice frying cylinder (3) into the top plate (5).

(S) is the desexing section (A) and the rotary sorting section jC) This space (P
), and a sensing valve L211 is installed in the lower part of the sensing housing (S) so that it can be operated with one end as a fulcrum. roll(
2) The adjusting plate adjusts the amount of VC supplied by sliding down, and moves up and down around the fulcrum axis to change the opening degree of the supply port I251.

It is an overflow tube (field), the upper part of which communicates with the overflow port (16), and the lower part of which penetrates the paddy tank (1) and looks into the upper part of the sensing casing (fs).

The sensing valve +Jl+ and the adjustment plate are interlocked and connected so that the overflow tube (of the supply port depending on the amount of fallen rice falling in the cave) can be adjusted to be narrower or wider.

Next, the bottom plate (11) and the mouth-shaped cover plate (27i) of the paddy tank (1) on the rotary sorting unit (0) side are connected to the paddy tank (1).
) is the paddy return path formed in the paddy tank (1
) The discharge side (Y) of the primary sorting cylinder (5) with its upper part communicating with the supply port 6) is connected to the lower part thereof. And the bottom plate (one primary sorting cylinder (5) forming the paddy return path (27I)
) is provided with an outlet (28) in the part directly below (Y), and a switching plate (29) with a cross-sectional opening shape that pivots on the downstream side and can be raised and lowered. This switching plate (2!l) has an elongated hole (31+) attached to the operating rod protruding from the cover plate d (301) in the vertical direction.

+D) is a foreign matter removal tube installed in parallel on the back of the above-mentioned sensing casing (S).
This sensing casing (S) is separated by a partition wall (39), and is located below the opening at the upper end (39 is the above-mentioned outlet (support)), and the lower part is at the wind selection part CB). It is in communication with a take-out gutter (34) formed in a cover that covers a transmission device (E) (not shown) that drives each shaft.

Therefore, the paddy in the paddy tank (1) is supplied from the supply port (i) to the pair of removal rolls (2), where it slides off, is sorted in the wind sorting section (B), and is removed from the rice-lifting barrel (3). ) at supply tank (T)
I get sore inside. This rice input σ/ζ is removed by the transfer device (

This fallen rice that falls one after another is supported by a rotating wheel (R) and flows toward the discharge (full tY) by the scooping action of the hollow (a) K of the primary sorting cylinder (5). During the transfer, the unpolished rice and some of the paddy are scooped up and dropped into the receiving gutter (8).Then they flow from the communication gutter 01 (11) into the secondary sorting cylinder (6). make it work. The sorting action within the secondary sorting cylinder (6) is carried out by the primary sorting cylinder (6).
It is the same as 5), but this secondary sorting cylinder (6) is adjusted so that only brown rice is scooped up into the receiving gutter (9).

Then, the paddy that was not scooped up by the primary sorting cylinder (5) enters the paddy return path (supply) from the discharge side (Y) and passes through the switching plate (29).
, it flows down on the bottom plate (11) and reaches the de-culling roll (2) from the supply port 125, where it is re-de-culped. One part of the brown rice and one part of the paddy that were not scooped up by the secondary sorting cylinder (6) are transferred to the circulation path f+.
The brown rice that flows down through the flow path (131) and is lifted up again by the sliding rice lifting tube (3) and scooped up into the receiving gutter (9) flows down from the flow path (131) onto the flow plate (14) and is wind-selected. After wind selection in section (B), the brown rice is taken out of the machine (4).

At that time, if the amount of paddy that is removed from the paddy tank (1) through the supply port +25) by the stripping roll (2) increases, the supply tank (T
) The amount of fallen rice stored in K is increased, and the surplus that is lifted up from the fallen rice lifting cylinder (3) overflows from the overflow port (16) and passes through the overflow cylinder (26) to the sensing cabinet (S). ) and accumulates on the lower sensing valve Ca1l, causing the operation to occur. The capacities of the rotary sorting section (A) and the rotary sorting section (C) are balanced and the rice hulling and sorting work is continuously operated.

However, the amount of rice that has fallen off at the removal section (A) is extremely large, making it difficult to automatically operate the adjustment plate (23) in the removal section.

) If V'rC flows into the rice removal tube (D), it gradually accumulates even though it reflows from the lower part into the rice lifting tube (3) and finally exceeds the upper edge of the partition wall C3 and enters the foreign matter removal tube (D). When it is taken out, it is taken out of the machine from the take-out gutter (34) and the operation continues.

If foreign matter is still mixed in the paddy being charged into the paddy tank (1), it will be raised by rotating the primary sorting cylinder (5) on the inner circumferential surface of the primary sorting cylinder (5).・An abnormal noise is emitted by the downward flow and the transition from the supply side (phantom to the discharge side (Y)). Especially in the case of metals, the abnormal noise at number 7 is so intense that it is possible to immediately detect the contamination of foreign matter.

At this time, if the upper end of operation 1+Gl+ was moved downward along the elongated hole, the switching plate 129 that would have closed the outlet example)
is in the state shown in the imaginary line in Figure 2, and at the same time opens the air outlet (support), blocks the paddy return path (a), and closes the primary sorting cylinder (5).
) Foreign matter and rice that are about to be discharged from (Y) fall from the take-out port (28), pass through the foreign matter take-out tube (D), and are taken out of the machine from the take-out foot.

As described above, the present invention is provided with a removal part on the upper side and a wind selection part on the lower side, and a large number of depressions are formed on the inner circumferential surface on the side of this removal part, so that one end side is to be sorted. A sorting cylinder with the grain supply side and the other end as the discharge side is rotatably installed horizontally, and a receiver is used to collect the sorted grains scooped up by the recess.
In a rotary sorting huller, in which a rotary sorting section equipped with a rotary sorting section is installed adjacently so that the above-mentioned discharge side becomes the dehulling section side, the scraped rice that is fed into the sorting cylinder is fed into the discharge side wall of the rotary sorting section. The supply tank is equipped with a sensing casing with a built-in sensing valve that connects the lower part to the grain tube for lifting rice grains and interlocks the adjustment plate for the amount of grains sliding down in the de-stripping section, and a sensing casing with the lower part connected to the outside of the machine and during the grain cylinder for scraping rice. A foreign matter removal cylinder for removing mixed foreign matter is provided between the culminating part and the rotary sorting part, and an overflow pipe communicating with an overflow port opened in the supply tank is extended in the earth part of the sensing box, and The paddy return path that communicates the discharge g1 of the sorting cylinder of the rotary sorting section with the de-processing section was switched to enable communication with the upper part of the foreign matter removal cylinder, and the sensing casing and the upper part of each of the foreign matter removal cylinders were communicated. Therefore, when there is foreign matter mixed in the husked rice, it is possible to switch the paddy return path and take it out of the machine from the foreign matter removal tube. Even if the capacities of the culling section and the rotary sorting section are no longer balanced and excess fallen rice flows into the sensing cylinder, it cannot be removed beyond the partition wall and out of the machine using the foreign matter removal cylinder. Although the structure is simplified without requiring a separate device for taking out the rice, it is possible to continue operation while preventing clogging due to dropped rice.
