Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a hulling and sorting machine, and more particularly to a paddy supply amount adjusting device of a hulling and sorting machine.

[Prior art]

Conventionally, in a hulling and sorting machine which is composed of a removing section provided with a pair of rolls, and a paddy / brown rice selecting section including an oscillating sorter, etc. (Hereinafter referred to as "polished rice") is conveyed to the sorting section by the grain lifting machine, but in order to constantly supply a certain amount of milled rice to the sorting section, connect it to the discharge section of the grain lifting machine, that is, supply it. A suspension tank 101 is provided as a part supply hopper (see FIG. 6). This hanging tank 101 is a spring centered on the fulcrum 103.
By being suspended by 102, the paddy supply amount control valve 104 is opened and closed in conjunction with this, and the supply amount to the roll is automatically adjusted. That is, a shaft 105 to which the paddy supply amount control valve 104 is fixed is pivotally supported on the lotto table 106 and both ends thereof are extended, a locking piece 113 is provided at one end, and a connecting arm 107 is provided at the other end.
Fix each. Then, by connecting the arm 107 and the suspension tank 101 by the load 108, the suspension tank 1
According to the amount of rice grains in 01, the paddy supply amount control valve 104 is interlocked to open and close, and the supply amount to the roll is automatically adjusted. In addition, the decapacity varies depending on the properties of the raw paddy and the type of prime mover.Therefore, the maximum opening of the paddy supply amount control valve 104 is performed to prevent overload of the prime mover and hunting (disturbance) of the storage amount of the suspension tank 101. The maximum supply was restricted by controlling the degree. That is, the shaft 1 for fixing the paddy supply amount control valve 104
Since the locking piece 106 provided at the end of 05 is locked by one end of the screw shaft 109 as a stopper when the paddy supply amount control valve 104 is opened to some extent, the hanging tank 101 approaches an empty state. Also, by regulating the paddy supply amount control valve 104 so as not to open above a certain level, a safe and proper supply amount can be maintained. Further, as a manual paddy supply amount adjusting means, a paddy supply amount adjusting piece is used.
There is a shutter 110 provided directly above 104. The shutter 110 is slidably formed by a lever 111 and is in a half-open state to reduce the amount of paddy supplied at the time of starting operation, and the brown rice sorted by the sorting unit is a mixed grain of paddy and brown rice ( (Hereinafter referred to as "mixed rice"), it circulates inside the machine, and when sliding rice and mixed rice have accumulated to a certain extent in the suspension tank 101, the shutter 110 is fully opened by the lever 111, and at the same time, a switching valve (not shown) is activated. By doing so, the brown rice outflow path is switched from “circulation” to “discharge”, and the brown rice is discharged to the outside of the machine to shift to normal operation.

[Problems to be solved by the device]

By the way, when the maximum supply amount of the paddy supply amount control valve 104 is reduced during operation, the dial 112 pivotally attached to the screw shaft 109 is rotated in one direction, and the screw shaft 109 is rotated in a direction to push back the locking piece 106. The locking piece 106 is interlocked with and connected to the suspension tank 101 via the shaft 105, the arm 107 and the rod 108, so that the spring 102 in the suspension tank 101 is prevented. Then, the dial 112 had to be turned, and it was not easy to adjust the maximum supply amount in the “decreasing” direction. Also, at the start of operation, the lever 111 is "shutter half open".
It is troublesome to manually switch from the shutter to the "shutter fully open" position, and if the time is lost, there is a possibility of causing a jam accident, poor sorting, insufficient capacity, etc. Furthermore, during operation, when the brown rice discharge lever is switched from “discharge” to “circulation” due to reasons such as poor sorting, the weight of brown rice that is recirculated into the suspension tank 101 causes the suspension tank 1
Since 01 is lowered and the paddy supply amount control valve 104 is half-opened or fully-closed, the paddy supply amount control valve 104 is in a substantially fully opened state, so a large amount of rice grains are supplied to the hanging tank 101 at a stretch and overflow. Sometimes. Therefore, there is a problem that the sorting state of the sorting unit is adversely affected, and damaged rice is generated due to double rolling of the roll. In consideration of these points, the present invention can easily reduce the maximum supply amount of the paddy supply amount control valve even during operation, and there is no error in switching the reduced supply to the maximum supply amount at the start of operation. It is a technical object to provide a paddy supply amount adjusting device for a paddy hull sorting machine which does not cause an overflow accident of a hanging tank at the time of circulation switching.

[Means for solving problems]

In order to solve the above-mentioned problems, the first idea of the paddy supply amount adjusting device of the paddy hull sorting machine of the present invention is as follows. A pair of derolling below the feed hopper 5 for the raw paddy
A hulling device 2 having 6,6 is provided. B. The hulling device 2 is additionally provided with a sorting device 3 for sorting the rice grains removed by the derolling rolls 6, 6. C. The supply hopper of the sorting apparatus 3 is suspended by a spring 54 to form a vertically movable suspension tank 19. D. Further, a rotating shaft 13 for fixing a paddy feed amount control valve 14 provided on a feed path from the feed hopper 5 for the raw paddy to the derolling roll 6.
A lock piece 39 for maximum flow rate regulation, which is locked by a stopper 44 that moves according to the operation of the maximum flow rate regulation dial 47, is provided at one end of the. E. An arm 40 for connecting to the suspension tank 19 via a rod 41 is provided at the other end of the rotating shaft 13. As described above, it is a paddy supply amount adjusting device for a paddy hull sorting machine comprising a. The arm 40 is provided with an elongated hole 42 that engages with the lower end of the rod 41. G. Even if the suspension tank 19 rises and the lower end of the rod 41 moves upward along the elongated hole 42, it does not come into contact with the upper end of the elongated hole, and only when the suspended tank 19 descends. A biasing means is provided for biasing the arm 40 upward so that the lower end of the arm pushes the lower end of the long hole 42 to rotate the arm 40. I took the technical means. And the second idea is A lever 50 for driving and stopping the sorting device 3 is provided in the paddy hulling device, and when the lever 50 is set to the stop position, the maximum flow rate restricting locking piece 39 is rotated to set the paddy supply amount control valve 14. The lever (50) is provided with a push rod (51) for a fully closed position. Re. In addition, the brown rice discharge path 28 and the mixed rice discharge path 30 of the sorting device 3
In the hulling device 2, the switching valve 31 which is urged to one side by the spring 38 is switched to the circulation side at the branch portion of the hulling device 2 so that the switching valve 31 is driven by half rotation. Rotating arm 35 pivotally mounted on valve motor 34 and switching valve 31
And are linked and connected by a wire 36 and a covering tube 37 that are pulled against the spring 38. Nu. Further, when the rotating arm 35 is located on the circulation side, the half-opening member that engages with the rotating arm 35 so that the paddy supply amount control valve 14 is set to the half-open position against the biasing means 48. Stop
49 is pivotally attached to the rotary shaft 13. I took the technical means.

[Action and effect]

When rice grains accumulate in the hanging tank 19, the hanging tank 19 and the rod 41 start descending against the spring 54. The lower end of the rod 41 pushes down the lower end of the long hole 42, and gradually rotates the paddy feed amount control valve 14 in the closing direction against the biasing means 48 to limit the feed amount of the raw paddy to the roll 6. Further, when the amount of stored polished rice in the hanging tank 19 decreases, the hanging tank 19 and the rod 41 start to rise by the spring 54, and the urging means.
By the arm 48, the lower end of the rod 41 and the lower end of the elongated hole 42 are kept in contact with each other, the arm 40 is rotated upward, and the paddy supply amount control valve 14 is opened.
The maximum flow rate is reached when the maximum flow rate regulating locking piece 39 is locked by the stopper 44, and the opening operation of the paddy supply amount control valve 14 is also stopped. To reduce the maximum supply amount, operate the maximum flow rate regulation dial 47 in the direction to close the paddy supply amount control valve 14
The arm 40 is free along the elongated hole 42 without changing the lower end position of the rod 41, that is, against the spring 54 of the hanging tank 19 via the locking piece 39 for controlling the maximum flow rate and the rotating shaft 13. It is rotated without doing. In this way, the arm 40 that connects the rod 41 and the rotating shaft 13
The maximum flow rate regulation dial is formed by forming a long hole 42 in the and providing a biasing means for biasing the arm upward.
The 47 can be operated easily. Then, when the lever 50 is in the "stop position", the push rod 51 pushes down the maximum flow rate restricting locking piece 39, whereby the arm 40 rotates downward through the rotation shaft 13, and the paddy supply amount is adjusted. The valve 14 is fully opened. At this time, the long hole 42 of the arm 40
This prevents the rod 41 and the spring 54 of the suspension tank 19 from interlocking. Further, when the lever 50 is moved to the “driving position” at the start of the operation, the push rod 51 and the maximum flow rate restricting locking piece 39 are disengaged, and the paddy supply amount control valve 14 is urged by the biasing means 48 of the arm 40. As a result, the maximum flow rate restricting locking piece 39 is opened until it is locked by the stopper 44. At this time, the rotating arm of the switching valve motor 34 is formed so as to bring the switching valve 31 to the circulation position at the start of operation. The half-opening locking piece 49 axially attached to the rotating shaft 13 is locked by 35, and the paddy supply amount control valve 14 is in a half-open state until the switching valve 31 switches to the discharge side. Further, during operation, when the switching valve 31 is temporarily put into the “circulation” state due to a sorting failure or the like, the switching valve motor 34
Is driven to rotate the rotating arm 35 by half, and the rotating arm 35 comes into contact with the half-opening stop valve 49 to rotate, thereby rotating the rotating shaft.
The paddy supply amount control valve 14 becomes a half-open device via 13. In this way, the rotary shaft 13 and the rod 41 are connected to the long hole 42 of the arm 40.
Lever 50 by connecting via
When controlling the paddy feed rate control valve 14 by the push rod 51
Can easily be fully closed. In addition, even if the lever 50 is suddenly operated to the drive side, while the switching valve 31 is in the “circulation position”, the paddle supply amount control valve 14 is forcibly opened by the half-opening locking piece 49. The shutter is not required, which simplifies the driving operation and the paddy supply amount control valve.
There is no mistake in switching 14 to the maximum supply side (the maximum opening is reached when switching valve 31 is switched to the "discharging position"). Further, when the switching valve 31 is operated on the "circulation" side during operation, the paddy supply amount control valve 14 is in a half-open state in conjunction with this, so that the suspension tank 19 is lowered so that the paddy supply amount control valve 14 is fully closed. Until then, the amount of raw rice hulls supplied to the inside of the machine is reduced, and the suspension tank 19 does not overflow.

29, the mixed rice discharge port 26 is connected to the screw conveyor 9 in the lower stage of the wind selection chamber 7 through the mixed rice discharge passage 30. In order to switch the brown rice discharged from the brown rice discharge port 25 to the brown rice discharge passage 28 and the mixed rice discharge passage 30, a switching valve 31 is provided at a branch portion between the brown rice discharge passage 28 and the mixed rice discharge passage 30. That is, the arm 33 is attached to one end of the switching valve shaft 32 that pivotally mounts the switching valve 31.
Is fixed, and the distal end of the arm 33 and the rotary arm 35 pivotally mounted on the switching valve motor 34 provided near the rotary shaft 13 of the detaching portion 2 are connected by the wire 36 and the covering pipe 37 thereof, and When the moving arm 35 is rotated to the position where the wire 36 is pulled most, the switching valve 31 is on the discharge side (two-dot chain line in FIG. 4), and conversely, when the wire 36 is rotated to the position where the wire 36 is most returned, the switching valve 31 circulates. It is formed so as to be switched to the side (broken line position in FIG. 4). The arm 33 is provided with a spring (coil spring) 38 for pulling the arm 33 toward the side opposite to the wire 36. Next, the relationship between the suspension tank 19 and the paddy supply amount control valve 14 will be described. A maximum flow rate regulating locking piece 39 is fixed to the peripheral surface of the front end of the rotating shaft 13 on which the paddy supply amount adjusting valve 14 is pivoted, in a direction substantially opposite to the paddy supply amount adjusting valve 14, A fan-shaped arm 40 is provided on the rear end face of 13 and the locking valve 39 for restricting the maximum flow rate is used.
It sticks in almost the same direction as. Then, the lower end of a rod 41 whose upper end is connected to the suspension tank 19 is bent to engage with a long hole 42 provided in the arm 40, while the maximum flow rate restricting locking piece 39 is provided.
Is an upper part, that is, the maximum flow rate controlling rotary plate 45 provided with a stopper pin 44 for restricting rotation of the paddy supply amount control valve 14 in the opening direction (downward direction) is provided in the vicinity of the maximum flow rate controlling locking piece 39. The position of the stopper 44 is changed by operating the maximum flow rate regulating dial 47 provided at the end of the shaft 46 projecting from the central portion of the maximum flow rate controlling rotary plate 45 in a direction that is vertical and rotatable. . Further, the upper end of the long hole 42 of the fan-shaped arm 40 does not come into contact with the lower end of the rod 41 even when the suspension tank 19 rises to reach the top dead center at the position where the maximum flow rate regulation dial 47 is set to the minimum flow rate. Is formed as. On the other hand, the rotating shaft 13 is provided in a direction in which the paddy supply amount control valve 14 is opened by a torsion spring 48 as a biasing means, that is, the fan-shaped arm 40.
Is urged in the direction to rotate upwards,
The lower end of 41 and the lower end of the long hole 42 of the arm 40 are always in contact with each other when the paddy rice is accumulated in the hanging tank 19, and when the hanging tank 19 descends to reach the bottom dead center, the paddy supply amount control valve. 14 is fully closed. Further, the rotation shaft 13 near the rotation arm 35 of the switching valve motor 34.
A half-opening locking piece 49 is vertically attached to the rotary arm 35.
Is rotated to the circulation position of the switching valve 31 (see the solid line position in FIG. 5), the half-opening locking piece 49 is rotated against the torsion spring 48, and the paddy is supplied through the rotation shaft 13. The quantity control valve 14 is forced to the half open position. At this time, since the arm 40 fixed to the end surface of the rotating shaft 13 and the rod 41 are engaged with each other through the elongated hole 42, the rotating shaft 13 is free to rotate regardless of the spring 54 of the hanging tank 19. It becomes possible with. In addition, the switching valve motor 34
When the rotation arm 35 is further rotated by half to reach the discharge position of the switching valve 31, the half-opening locking piece 49 is disengaged from the rotation arm 35, and the paddy supply amount control valve 14 is a torsion spring. It rotates in the opening direction by 48, and the maximum flow rate restricting locking piece 39 is locked by the stopper 44, or at the position where the lower end of the elongated hole 42 of the fan-shaped arm 40 and the lower end of the rod 41 are engaged. Will stop. A lever whose one end projects to the front surface (operation portion) of the hulling device 2.
The wire 50 is provided in the vicinity of the lottery table 12 so as to be horizontally rotatable by a support shaft 50a, and the wire 52 for driving and stopping the swinging operation of the screening plate 20 of the screening unit 3 and its coating are provided at the other end. Tube 53
Are connected (for example, by a clutch mechanism that causes a tension pulley of a belt that swings the selection plate 20 to come into and out of contact). Further, the lever 50 is fixed to the other end of the push rod 51, one end of which is directed to the maximum flow rate restricting locking piece 39, and the lever 50 is in the "stop position" (see the dashed line in FIG. 4).
In case of, the push rod 51 pushes down the maximum flow rate restricting locking piece 39 against the torsion spring 48, whereby the rotating shaft 13 is rotated and the paddy supply amount adjusting valve 14 is fully opened. On the other hand, when the lever 50 is moved to the “driving position” (see the solid line in FIG. 4), the wire 52 drives the sorting device 3 and the push rod 51 retracts from the restricting locking piece 39, and the torsion spring 48. As a result, the paddy supply amount control valve 14 is opened. In addition, when the lever 50 is in this position, that is, during operation, in order not to cause a jam accident of each part of the transport unit due to stopping the main motor M1, a limit switch 55 that disconnects the relay circuit that turns the main motor M1 on and off. Is provided so that the main motor M1 is not stopped during operation. The specific operation of the above embodiment will be described below. The raw material paddy is put into the supply hopper 5, the power is turned on, and the main motor M1 is driven. At this point, so-called initial setting is performed, the clearance between the derolling rollers 6, 6 is set by the derolling driving motor M2, and the switching valve motor 3
4 is driven to position the switching valve 31 on the circulation side. When the initial setting is completed in this way, the lever 50 is moved to the driving side, the clutch (not shown) for driving the sorting plate 20 by the wire 52 is connected, and the sorting plate 20 is swung, and the push rod 51 and the maximum flow rate are set. The restricting locking valve 39 is disengaged, and the half-opening locking valve 49 is locked by the rotating arm 35 to make the paddy supply amount control valve 14 half-open. As a result, the paddy in the feed hopper 5 flows down to the space between the derollers 6 and 6 through the lottery stand 12, but the paddy feed amount control valve 14 and the guide gutter 43.
The raw material paddy supply port 15 formed in the gap between and is semi-open,
The lever 50 is suddenly moved to the drive side, and the push rod 51
Even when the engagement between the maximum flow rate restricting locking piece 39 and the maximum flow rate restricting piece 39 is released, a stop accident due to an overload of the main motor M1 does not occur. The rice grains that have been deactuated by the derolling rolls 6, 6, that is, the polished rice, are wind-selected in the wind-selecting chamber 7 to remove rice husks and immature grains, and then passed through the screw conveyor 9 and the bucket elevator 4 to be placed in the hanging tank 19. Saved. Then, when the polished rice has accumulated in the hanging tank 19 to some extent (it may be detected by a level sensor or the like), the discharge port of the hanging tank 19 opens a certain degree (motor or the like is not shown), and the smoothed rice is leveled. Supply to each sorter 20 via 21. When an appropriate amount of milled rice is supplied to the sorting plate 20 (a sensor is appropriately provided and detected), brown rice is shaken up, paddy is shaken down, and mixed rice is biased in the middle. , Respectively, from the paddy discharge port 24, the brown rice discharge port 25, and the mixed rice discharge port 26. Then, the paddy is fed to the roll 6 through the return paddy thrower 18, the return paddy bypass 17, and the return paddle supply port 16 to be deacted again. Is recirculated. By the way, since the switching valve 31 is still on the circulation side at that time, brown rice flowing out from the brown rice discharge port 25 is also guided to the screw conveyor 9 through the mixed rice discharge passage 30 and returned to the hanging tank 19, but it is constant. Condition, for example, the sensor of the sorting plate 20 outputs a normal signal, the level sensor provided in the hanging tank 19 detects “there is grain”, and the removal rate sensor (provided near the discharge part of the bucket elevator 4 ( (Not shown)
Switch action motor 34
Drives to rotate the turning lever 35 a half turn, and switches the switching valve 31 to the discharge side against the spring 33. As a result, brown rice is taken out of the machine as brown rice from the brown rice thrower 29,
At the same time, the engagement between the half-opening locking piece 49 and the rotating lever 35 is released, and the paddy supply amount control valve 14 is such that the maximum flow rate regulating meter locking piece 39 is engaged with the stopper 44 or the arm 40 is provided. It is opened to a position where the lower end of the long hole 42 and the lower end of the rod 41 are engaged with each other to be in the “fully opened” state. As a result, the hulling / sorting operation shifts to the normal operation, and even if the feeding state (feeding flow rate) of the raw paddy into the roll 6 is slightly different, the paddy feed amount control valve 14 is moved by the vertical movement of the hanging tank 19.
Subtly opens and closes to continue normal operation. For example, if the paddy supply is too large or too small, or if it is a hanging tank.
When the amount of accumulation in 19 causes hunting, the maximum flow rate regulating dial 47 is adjusted by rotating it in the increasing or decreasing direction. That is, when increasing the maximum flow rate, the position of the stopper 44 is moved so that the maximum flow rate restricting locking piece 39 rotates upward (clockwise in FIG. 5), and conversely, when the maximum flow rate is decreased. Rotates the position of the stopper 44 in the opposite direction to the above. In this weight reduction operation, the arm 40 and the rod 41 are connected through the elongated hole 42, and moreover, the torsion spring 48 is urged so that the lower end of the rod 41 and the lower end of the elongated hole 42 are always in contact with each other. Direction to reduce the maximum flow rate,
That is, the lower end of the rod 41 and the lower end of the long hole 42 can be easily moved in a direction away from each other, and the adjusting operation of the maximum flow rate regulating dial 47 is easy. At the end of operation or at the time of temporary stop, the push rod 51 pushes the maximum flow rate regulating locking piece 39 by returning the lever 50 to the "stop position" on the lottery table 12 side, so that the paddy supply amount control valve 14 is fully closed. Become. Also in this case, the long hole 42 of the arm 40 allows the paddy supply amount control valve 14 to be easily closed without interlocking with the rod 41. Further, by moving the lever 50, the swinging motion of the selection plate 20 is also stopped, and the discharge port of the hanging tank 19 is also closed by a motor (not shown). When any one of the conditions for shifting to the normal operation is deviated, the notch valve motor 34 is activated to rotate the rotating arm 35 half a turn, thereby making the switching valve 31 on the circulation side and half open. The suspension tank 49 is rotated so that the paddy supply amount control valve 14 is opened halfway to reduce the supply flow rate of the raw paddy and the hanging tank 19
Prevent overflow accidents. If the above conditions are satisfied again, the switching valve motor 34 is driven to set the switching valve to the discharge side and the paddy supply amount control valve 14 is fully opened to shift to the normal operation.
