It is formed to rotate in steps.

An engagement plate 58 is fixed to the front end of the valve shaft 6 of the supply valve 7, and the engagement plate 58 and a maximum flow restricting rotation rotatably provided on the fixed plate 34 by a knob 60. The restricting pin 61 of the board 59 is formed so as to be engaged, and the pressing piece 62 formed of a leaf spring fixed to the lever shaft 33 and the engaging plate 58 are formed so as to be engaged. Further, an arm 63 is fixed to the other end of the valve shaft 6, and the arc-shaped long hole 64 formed in the arm 63 and the suspension tank 17 are connected by a connecting rod 65. The valve shaft 6 is always urged by a spring 66 in a direction to open the supply valve 7.

The specific operation of the above embodiment will be described below. Raw material paddy is supplied into the stuffing hopper 4 by a chute pipe or the like (not shown). At this time, the lever 36 is at the position shown in FIG. 4A, the engaging piece 58 is pressed by the pressing piece 62 against the spring 66, the valve shaft 6 is rotated, and the supply valve 7 is fully closed. . Further, since only one wire 45 is pulled by the pulling arm 39 and the movable tension pulley 50 is separated from the V-belt 49, the swing sorting plates 22 are in a stopped state, and the switching valve 31 is connected to the arm 71. , The valve shaft 57 is pulled by the spring 56 and is in an in-machine circulation state (see a two-dot chain line in FIG. 3). Furthermore, since the connecting rod 43 is drawn downward against the spring 44 by the long hole 38 of the rotating plate 37,
Since the opening / closing valve 20 closes the downflow path of the mixed rice via the arm 42 and the valve shaft 41, the mixed rice remaining in the suspension tank 17 falls, and the rocking sorter plate 22 which is stopped is stopped.
... does not stay in the supply section (equalizer).

Next, when the lever 36 is turned upward, the valley-shaped articulating machine 70 is rotated by about 45 ° against the spring 73, and is again engaged with the chevron-shaped articulating machine 72 and locked (FIG. 4). B),
It becomes a so-called neutral state. At this time, as the pressing piece 62 rotates upward, the engagement plate 58 and the valve shaft 6 rotate by the spring 66, the supply valve 7 is half-opened, and the raw material in the insertion hopper 4 is gradually removed. Feeding is performed between the removal rolls 8 and 9 to start the hulling. Further, the wire 45 is loosened by the rotation of the rotation plate 37, and the movable tension pulley 50 is pulled by the spring 54 via the attachment body 51, and the V belt 4
9 is tensioned and the swing mechanism is driven to swing the swing sorter plates 22..., And the open / close valve 20 is opened by the spring 44 so that the mixed rice in the suspension tank 17 is separated by the secondary air sorting device. It flows down while being selected by wind, and is supplied to each of the rocking sorting plates 22 through an equalizer to be sorted. However, at this time, the switching valve 31 remains on the circulation side in the machine, and the brown rice separated by the brown rice partition plate 24 flows down to the mixed rice flow path 27, and together with the mixed rice, the mixed rice receiving trough 12 and the mixed rice thrower. It is returned to the suspension tank 17 by 16. When the mixed rice accumulates in the suspension tank 17, the spring 19
When the suspension tank 17 rotates downward against the lower end of the arm 63, the lower end of the connecting rod 65 engages with the lower end of the long hole 64 of the arm 63 at the time when the suspension tank 17 has accumulated over a certain amount, and pushes down the arm 63 against the spring 66.
The supply valve 7 is gradually rotated in the closing direction via the valve shaft 6, and finally, the supply of the raw material paddy from the filling hopper 4 is stopped in the fully closed state (even in this state, the swing sorting plate 22 The paddy sorted in ... is returned by the paddy thrower 28 and returned between the rolls 8 and 9).

On the other hand, in the oscillating sorting plates 22..., The mixed rice at a constant flow rate is supplied from the suspension tank 17 and the sorting state is stabilized. After confirming that there is no mixing, the lever 36 is turned upright to shift to a steady operation. As a result (see FIG. 4C), the engagement between the pressing piece 62 and the engagement plate 58 is released, and the engagement plate 5 biased by the spring 66 is released.
8 is locked by the regulating pin 61, the supply valve 7 becomes a fully open body, the wire 46 is pulled by the pulling arm 40, and the arm 71 and the valve shaft 57 are rotated against the spring 56 to switch. The valve 31 is switched to the outside discharge side (indicated by a solid line in the drawing), and the finished brown rice flows into the brown rice flow passage 30 from the brown rice dropping port 29 and is taken out of the machine by the finished rice thrower 32. . At this time, the connecting rod 43 of the opening / closing valve 20 and the wire 45 on the movable tension pulley 50 side are not in a state of being pulled together.
The swing mechanism is driven, and the opening / closing valve 20 is kept open.

In this way, the steady operation is continued. However, when the amount of the raw material paddy fed into the rolls 8 and 9 is increased due to a change in the properties of the raw material paddy or the like, the downward movement accompanying the increase in the storage amount of the suspension tank 17 is performed. By the rotation, the lower end of the connecting rod 65 is moved to the arm 63.
The lower end of the long hole 64 is depressed, and the supply valve 7 is rotated in the closing direction to reduce the amount of feeding, thereby preventing a problem such as overflow of the suspension tank 17. Will be stored.

Next, another embodiment of the present invention will be described with reference to FIGS. 5 and 6 (the same reference numerals are used for the same members as in the previous embodiment). A lever shaft 80 is horizontally suspended near and parallel to the valve shaft 6 by a pair of fixed plates 34 and 35 so as to be rotatable.
Are pivotally mounted on the other end, respectively. The rotating plate 81
Has an elongated hole 38 for engaging the lower end of a connecting rod 43 whose upper end is connected to the arm 42 of the opening / closing valve 20, and an engaging pin 85 is fixed thereto. On the other hand, a driven shaft 82 is provided laterally near the lever shaft 80 and parallel to the lever shaft 80. The driven shaft 82 is suspended between a pair of fixed walls 83, 83, and has a tension plate 84 at one end. The tension plate 84 is provided with a long hole 86 into which the engagement pin 85 is loosely fitted.
A pair of arc-shaped long holes 87 and 88 are provided with the driven shaft 82 interposed therebetween. Then, the locking end 46a of the wire 46 for operating the switching valve 31 is loosely fitted into the one long hole 87,
The locking end 45a of the wire 45 for operating the movable tension pulley 50 is loosely fitted in the other long hole 88.

In the case of this embodiment, the lever shaft 80 and the rotary plate 81 are rotated by the lever 36, and the driven pin 82 is slid along the elongated hole 86, so that the driven shaft 82 is moved. The tension plate 84 is rotated about the center. That is, in FIG. 5, when the lever 36 is rotated from the operation start position indicated by the solid line to the vertical side (operation position), the engaging pin 85 slides while pushing down the lower line of the long hole 86, thereby causing the tension plate 84 to slide. It turns to the right in the figure, and one wire 46
6, the switching valve 31 is switched to the outside discharge side. Conversely, when the pin is rotated from the position shown by the solid line to the horizontal side (stop position), the engaging pin 85 slides while pushing up the upper edge of the elongated hole 86, and the tension plate 84 rotates to the left in the figure. , The other wire 45 is pulled against the spring 54, the tension of the V-belt 49 by the movable tension pulley 50 is released, and the swing of the swing selection plates 22 stops.
As described above, in the present embodiment, the engaging pin 85 is moved from one end of the elongated hole 86 to the other end to serve as a positioning stopper. The operation of the other members is the same as that of the previous embodiment, and the description is omitted. In order to smooth the sliding of the engaging pin 85 and the operability of the lever 36, the middle of the elongated hole 86 may be slightly expanded to form an elliptical shape.

[0025]

As described above, according to the present invention, by one lever, the supply valve is fully closed when the operation is stopped, the switching valve is set to the circulation side in the machine, the swing sorting plate is stopped, and the operation is started when the operation is started. The supply valve is opened halfway, the switching valve is set to the circulation side in the machine, and the swing selection plate is driven.In the normal operation, the supply valve is fully opened to drive the swing selection plate and the switching valve is set to the outside discharge side. Therefore, at the start of operation, the switching valve is always on the circulation side in the machine, and at this time, the supply valve is in a half-open state, and even if the suspension tank is empty, a large amount of raw material paddy is rapidly supplied between the removal rolls. In addition, brown rice is not discharged out of the machine while the sorting state of the swing sorting plate is not stable. Also, when the supply valve is fully closed, that is, when the swinging sorting plate is stopped, the mixed rice flow path below the suspended tank is closed. Therefore, even if the operation is stopped while the suspended rice is stored in the suspended tank, the suspended rice remains in the suspended tank. The mixed rice is not deposited on the supply section of the swinging sorting plate, and the operation can be smoothly resumed.
