The lower part of the foreign matter removal tube communicates with a takeout gutter formed in the cover that covers the transmission device that drives each shaft in the wind sorting section, and the foreign matter removal tube is connected to a takeout gutter formed in the cover that covers the transmission device that drives each shaft in the wind sorting section. The material is removed from the machine as appropriate on the way from the end of the sorting action on the inner periphery of the sorting cylinder, which is easy to detect, i.e. from the discharge side to the detachment part, and the cover that covers the transmission device is used to ensure safe and smooth removal. The present invention also relates to a foreign matter removal device in a rotary sorting huller for the purpose of preventing an operator from forgetting to attach a cover to a transmission device.

Hereinafter, explanation will be made with reference to the drawings of the embodiments.A is a dehulling section, which consists of a paddy tank 1 and a pair of derolling 2, etc., and B is a wind sorting section, which wind-selects and rotates the fallen rice from the dehulling section A. It is in charge of the wind selection of brown rice sorted in sorting section C.
Reference numeral 3 is a rice-lifting cylinder for suri-roki rice, and reference numeral 4 is a brown rice-lifting machine. The rotary sorting section C separates the fallen rice that has been deflated and sorted by the shedding section A and the wind sorting section B into brown rice and paddy. A removal part A is placed above the front part of the wind sorting part B, and a rotary sorting part C is placed above the rear part.

In the rotary sorting section C, 5 and 6 are primary and secondary sorting cylinders having a large number of depressions a formed in their inner circumferential surfaces, and are arranged vertically and are rotatable in a substantially horizontal state to be sorted. The supply side X and the discharge side Y are connected by rolling wheels R.
This discharge side Y is adjacent to the removal part A. Inside the primary sorting cylinder 5, there is installed horizontally a transfer device b that transfers the scraped rice from the discharge side Y to the supply side X and drops it onto the inner circumferential surface of the sorting cylinder 5. In parallel, a receiving trough 8 incorporating a screw conveyor 7 for receiving and taking out the sorted material scooped up by the depression a is installed horizontally, and the paddy tank 1 of the removal section A is used to discharge the primary sorting cylinder 5. It is located below side Y.

Further, a receiving gutter 9 is provided horizontally within the secondary sorting cylinder 6 to receive the sorted material scooped up by the recess a, and 10 and 11 are provided on the supply side X and are arranged inside the primary sorting cylinder 5. 12 is a communication gutter that allows the sorted material received in the receiving gutter 8 to flow into the secondary sorting cylinder 6; 12 is a circulation path that communicates the discharge side Y of the secondary sorting cylinder 6 and the fallen rice frying cylinder 3; 13; The brown rice in the receiving gutter 9 is transferred to the flow plate 1 of the wind sorting section B.
4.

T is a supply tank for the fallen rice, which is attached to the side wall 15 on the upper side of the removal section A, that is, on the discharge side Y, the lower part communicates with the starting end of the transfer device b, and the upper part is filled with excess fallen rice. A window 19 in which a transparent body 18 can be freely inserted and removed is provided in the outlet 16 and a wall 17 adjacent to the overflow outlet 16, and the top plate 20 is fitted with the tip of the dropped rice frying cylinder 3.

S is a sensing housing provided in a space P between the removing section A and the rotating sorting section C, and a sensing valve 2 is installed in the lower part of this sensing housing S.
1 is movable at one end with a support shaft 22 as a fulcrum, and 23 supplies the paddy in the paddy tank 1 to the deroller 2. The fulcrum shaft 2 is an adjustment plate that adjusts the amount of sliding.
4 to change the opening degree of the supply port 25.

26 is an overflow cylinder, the upper part of which is the overflow port 16.
In addition, the lower part passes through the paddy tank 1 and communicates with the upper part of the sensing casing S, respectively.

The sensing valve 21 and the regulating plate 23 are connected to the overflow cylinder 2.
The supply port 25 is interlocked to be adjusted to be narrower or wider depending on the amount of dropped rice falling through the feed port 6.

Next, 27 is a paddy return path formed in the paddy tank 1 by the bottom plate 1' of the paddy tank 1 on the rotary sorting section C side and a shaped cover plate 27', and the upper part is visible above the paddy tank 1. They communicate with the discharge side Y of the primary sorting cylinder 5 to receive the material flowing out from the discharge side Y, and the lower portions thereof communicate with the supply ports 25, respectively. And the primary sorting cylinder 5 of the bottom plate 1' forming the paddy return path 27
There is an outlet 28 on the high place side directly below the discharge side Y.
The outlet 28 is provided with a switching plate 29 having a freely undulating cross-sectional shape with its downstream side pivoted, and the switching plate 29 has a long hole 30 formed vertically in the cover plate 27'. An operating rod 31 that protrudes from is attached.

Reference numeral D denotes a foreign object extraction cylinder, which is arranged in parallel on the back side of the sensing case S, the opening 32 at the upper end is located below the extraction port 28, and the lower part is a transmission device E (not shown) that drives each shaft in the wind selection section B. It communicates with a take-out gutter 34 formed in a cover 33 that covers the.

Therefore, the paddy in the paddy tank 1 is supplied from the supply port 25 to the pair of de-rolls 2 and is slid down to the wind sorting section B.
The rice is sorted and the rice is fried in the tank 3 and supplied to the tank T.
It is put inside. This thrown-in rice is transferred to the supply side X by the transfer device b and sequentially falls into the primary sorting cylinder 5. While moving toward the discharge side Y while flowing due to the scooping action by the hollow a of the body 5, the brown rice and a part of the paddy are scooped up and dropped into the receiving gutter 8, and then from the communicating gutter 10, 11 to the communicating gutter 2. It is caused to flow into the secondary sorting cylinder 6 to perform a secondary sorting action. 2
The sorting action within the secondary sorting cylinder 6 is similar to that of the primary sorting cylinder 5, but the secondary sorting cylinder 6 is adjusted so that only brown rice is scooped up into the receiving trough 9.

The paddy that has not been scooped up by the primary sorting cylinder 5 enters the paddy return path 27 from the discharge side Y and enters the switching plate 2.
9. It flows down on the bottom plate 1', reaches the unrolling part 2 through the supply port 25, and is taken off again. One part of the brown rice and one part of the paddy that were not scooped up by the secondary sorting cylinder 6 flowed down in the circulation path 12, were lifted up again by the brown rice lifting cylinder 3, and were scooped up into the receiving gutter 9. The brown rice flows down from the channel 13 onto the flow plate 14, is wind-selected in the wind-selecting section B, and then taken out of the brown-rice grain lifting machine 4.

At that time, if the amount of unrolled paddy from the tank 1 through the supply port 25 increases, the supply tank T
The amount of dropped rice stored in the box increases, and the surplus lifted from the dropped rice lifter cylinder 3 overflows from the overflow port 16 and flows into the sensing casing S through the overflowing cylinder 26, where it flows into the sensing valve 21 at the bottom.
This operation is performed by interlocking the adjustment plate 23 to adjust the opening degree of the supply port 25 to the narrower side, so that the capacities of the removal section A and the rotary sorting section C are balanced, and the rice grain is removed. The sorting operation is operated continuously.

By the way, if foreign matter is mixed in the paddy put into the paddy tank 1, the rotation of the primary sorting cylinder 5 on the inner peripheral surface of the primary sorting cylinder 5 will cause the rice to rise.
The downward flow and the transition from the supply side X to the discharge side Y produce an abnormal noise, and especially in the case of metals, the noise is so loud that the contamination of foreign matter can be immediately detected. At this time, if the upper end of the operating rod 31 is moved downward along the elongated hole 30, the switching plate 29 that had been blocking the outlet 28 will be in the state shown in the imaginary line in FIG. Foreign matter and rice that block the return path 27 and are about to be discharged from the discharge side Y of the primary sorting cylinder 5 fall from the outlet 28, pass through the foreign matter removal cylinder D, and are covered by a cover 33 that covers the transmission device E.
It will be taken out of the machine through a take-out gutter 34 formed in the.

As described above, the present invention has a removing section on the upper side and a wind sorting section on the lower side, and a large number of depressions are formed on the inner peripheral surface on the side of this removing section, and one end side is the supply side of grains to be sorted. A sorting cylinder with the other end as a discharge side is installed horizontally so that the discharge side can be detached and rotated,
A rotary sorting section equipped with a receiving gutter to take out sorted grains scooped up by the recess is provided, and the paddy tank of the removing section is positioned below the discharge side of the sorting cylinder so that the grains flow out from the discharge side. is passed through a paddy return path formed in the paddy tank, and the high side of the paddy return path can be communicated with a foreign matter removal cylinder whose lower part is led out onto a transmission device that drives each shaft in the wind sorting section. It is configured to be switchable, and the cover that covers the transmission device is configured with a take-out gutter that communicates with the lower part of the foreign matter removal tube when installed, so that if foreign matter is mixed in the paddy, it can be sorted out. When the paddy and brown rice are sorted in the cylinder, foreign objects come into contact with the inner circumferential surface of the sorting cylinder and make an abnormal noise, and the operator immediately detects the presence of the foreign objects and removes them from the machine through the foreign object removal cylinder. It can be taken out. Moreover, the lower part of this foreign matter removal tube is led out onto the transmission device that drives each shaft in the wind selection section.
The transmission device can be taken out safely and smoothly using a takeout gutter formed in the cover covering the transmission device.

Therefore, by attaching a cover to the transmission device at the bottom of the foreign matter extraction tube, the extraction gutter formed in this is communicated and serves as the extraction gutter, so the cover is attached. Otherwise, the foreign objects taken out from the foreign object removal tube will fall into the transmission device, make an abnormal noise, and scatter, which will alert the worker and prevent them from forgetting to put on the cover, making work safer. It became possible to do this.
