Description

[Detailed description of the invention] The present invention is a rice huller that can adjust the gap between the removal rollers by manual operation when the solenoid mechanism that automatically adjusts the gap between the removal rollers provided in the removal section is not in operation. This invention relates to a gap adjustment device for removing rollers.

In general, the removal roller installed in the removal section of a huller is worn out in proportion to the removal time and efficiency.
There are some, such as the one proposed in No. 162076, in which an operating pawl operated by a solenoid mechanism is engaged with a ratchet mechanism, and the gap between the rollers to be removed is automatically adjusted by rotation of the ratchet mechanism.
Regardless of whether the solenoid mechanism is activated or not, the operating pawl is always engaged with the ratchet gear, so in order to manually adjust the clearance between the rollers, it is necessary to take care not to damage the ratchet mechanism, etc. The engagement of the actuating claws must be manually released each time, which is cumbersome to operate, and the automatic adjustment device may be damaged if the actuating claws are not released.

The present invention was devised in view of the above-mentioned circumstances and to eliminate these drawbacks, and its purpose is to provide a release mechanism that releases the engagement of the operating pawl when the solenoid mechanism is not activated. Therefore, when the solenoid mechanism is not in operation other than when the solenoid mechanism is activated, the gap between the rollers for removing rollers in the huller can be adjusted immediately by hand without the need to release the actuating pawl in the ratchet mechanism. The aim is to provide the equipment.

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. Reference numeral 1 is a rice huller, and on one side of the base 2 of the rice huller 1 there is a mangok sorting section 3. , and a removal part 4 is provided on the other side. A funnel 5 is installed at the top of the removal section 4, and the funnel 5
The paddy stored in advance is dropped and supplied between a pair of removal rollers 6 and 6a provided in the removal section 4. One of the roller removing rollers 6, 6a, the removing roller 6a, is pivoted at the midway point of a support rod 7 whose base end on the machine body side is swingably supported. The opposing gap between the removing rollers 6 and 6a can be freely moved toward and away from each other by the movement.

On the other hand, 8 is a ratchet mechanism fixed to the manual adjustment handle 12.
A guide rod 10 having a female thread concentric with the axis of the ratchet gear 9 of the ratchet mechanism 8 is integrally extended and fixed toward the release rollers 6, 6a on one side in the axial direction. . Reference numeral 13 denotes an adjustment rod whose one end side is screwed into the guide rod 10 of the adjustment handle 12,
The other end of the adjustment rod 13 is brought into contact with a pin 26 of a spring holder 25 pivotally connected to the tip of the support rod 7, and is used to select between manual rotation of the manual adjustment handle 12 and rotation of the ratchet gear 9. By moving in and out, the supporting rod 7 can be swung to freely adjust the opposing gap between the release rollers 6 and 6a. Reference numeral 14 denotes a support rod protruding from the body side, and a cylindrical member 15 is rotatably fitted into the shaft portion of the support rod 14. A support protrusion 16a protruding from a support 16 that rotatably supports the outer periphery of the guide rod 10 is fitted into a fitting hole 15a eccentrically bored in the cylindrical member 15. Operation handle 1 provided on the shaped member 15
By rotating 5b in the direction of arrow A,
Manual adjustment handle 12 with ratchet gear 9
The adjusting rod 13 moves integrally in the longitudinal direction toward the axial direction of the adjusting rod 13, so that the opposing gap between the removing rollers 6 and 6a can be rapidly adjusted to open and close.

17 is a solenoid mechanism, and the solenoid mechanism 17 is mounted on a support base 18 that is integrally fixed to the support body 16. Furthermore, the solenoid mechanism 17 is connected to a detection timer mechanism 19 that detects the operating time of the releasing rollers 6, 6a, and operates at predetermined time intervals corresponding to the operating time of the releasing rollers 6, 6a, Actuating rod 21 against 20
It is becoming more immersive. On the other hand, when the operating rod 21 is retracted, an operating pawl 22 pivotally attached to the tip of the operating rod 21 engages with the ratchet gear 9, rotating the ratchet gear 9 and adjusting the adjustment rod. 13, and release roller 6,
The opposing gaps 6a can be made closer to each other by an amount commensurate with the amount of wear. When the solenoid mechanism 17 is not operating, the operating rod 21 is operated by the operating claw 2.
2 together with the compression bullet 20 to protrude and return to the ratchet mechanism 8 side, but at this time, the operating pawl 22
is moved upward while being guided by a guide protrusion 23 fixed to the support 16, thereby releasing the engagement of the operating pawl 22 with the ratchet gear 9.

Further, FIG. 6 is a wiring diagram showing the relationship between the detection timer mechanism 19 and the solenoid mechanism 17 used in this embodiment, where 29 is a power supply, 30
is the timer required for the solenoid mechanism 17, 30a
is its contact, 31 is a timer for turning off the solenoid mechanism 17, 31a is its contact, and 32 is a detection switch that detects the deactivation of the deactivating rollers 6, 6a. When the detection switch 32 is turned ON, the contact 31a is closed when no current is flowing through the timer 31.
It turns ON and the timer 30 operates. When the timer 30 operates for a predetermined period of time, the contact 30a is turned on, the solenoid is energized, and the solenoid mechanism 17 is activated. At the same time, current flows to the timer 31 and it starts operating, and after operating for a predetermined period of time, the contact 31a turns OFF and the timer 31 starts operating.
0 stops, contact 30a also turns OFF,
The solenoid is demagnetized and returns to its original state. That is, in connection with the turning on of the sensing switch 32, the timers 30 and 31 are activated, and the solenoid mechanism 17 is activated in accordance with the substantial operating time when the sensing switch 32 is turned on.

In the figure, reference numeral 24 denotes an energizer interposed between the operating claw 22 and the support base 18, and a tension spring 27 whose one end is fixed to a spring holder 25.
is the spring holder 2 screwed into the adjustment rod 13
8, and applies a predetermined pressure between the derollers 6 and 6a.

Next, the operation of the present invention constructed as described above will be explained. Now, if we feed paddy to funnel 5,
The paddy is removed in the removing section 4, wind-sorted, and then sent to the Mangoku sorting section 3 by the elevator (thrower), where it is sorted into paddy, mixed rice, and brown rice. Then, in the Mangoku sorting section 3, the paddy is returned to the removal section 4, and the mixed rice is again supplied to the Mangoku sorting section 3, where it is subjected to the removal and sorting operations, respectively.
The brown rice that has leaked out of the mangoku sorting section 3 is wind-sorted and then discharged outside the machine, which is the same as in the conventional huller.

In the above series of hulling operations, in the removal section 4,
The paddy falling from the funnel 5 is removed from the rollers 6, 6.
The removal rollers 6 and 6a are worn out in direct proportion to the removal time, so the removal rollers 6 and 6a are set in advance depending on the paddy conditions such as the moisture content of the paddy, the mixing rate of rice grains, and the quality. The solenoid mechanism 17 is operated at every predetermined operating time by the detection timer mechanism 19 in which the operating time is set. When the solenoid mechanism 17 is actuated, that is, when the operating rod 21 moves in the direction of arrow B, the operating pawl 22 moves in the direction of arrow B while meshing with the ratchet gear 9, and rotates the ratchet gear 9 by a predetermined angle for adjustment. Rod 13
By moving the removing roller 6a by an amount commensurate with the amount of wear on the removing rollers 6, 6a, removal can be performed with an optimum gap at all times.

By the way, the above-mentioned paddy conditions may change at the start of de-work and during the work, so
In this case, of course, according to this, the release roller 6,
The gap at 6a must be readjusted. At this time, when the solenoid mechanism 17 is not operating, the operating pawl 22, which has moved toward the ratchet mechanism 8 together with the operating rod 21, is moved upward while being guided by the guide protrusion 23, and the meshing with the ratchet gear 9 is prevented. Since it is in the released state, adjust the adjustment handle 1.
2 can be manually rotated to readjust the gap between the release rollers 6 and 6a. Therefore, the adjustment handle 1 can be adjusted while lifting the operating claw 23 by hand as in the conventional case.
2 does not need to be manually rotated, and therefore changes in paddy conditions can be dealt with immediately by only manual operation of the adjustment handle 12, and the ratchet mechanism 8 may be damaged if the operator forgets to release the operating pawl 23. There is no such thing.

In summary, the present invention provides a hulling machine in which an operating pawl operated by a solenoid mechanism is engaged with a ratchet mechanism, and the gap between the removal rollers is automatically adjusted by rotation of the ratchet mechanism.
The above-mentioned ratchet mechanism is provided with a release mechanism that releases the engagement of the operating pawl with the ratchet gear when the solenoid mechanism is not in operation, thereby making it possible to manually adjust the gap between the release rollers when the solenoid mechanism is not in operation. Although the gap between the removing rollers can be automatically adjusted according to the amount of wear on the removing rollers, if you want to adjust the gap between the removing rollers independently of the automatic adjustment, a release mechanism can be used to release the solenoid. Since the engagement between the operating claw of the mechanism and the ratchet gear is released, adjustment can be easily made by simply rotating the manual adjustment handle without having to release the operating claw one by one as in the conventional case. Therefore, there is no damage to the ratchet mechanism due to forgetting to release the operating claw of the solenoid mechanism, and the gap between the rollers can be adjusted quickly. This is something that can be improved.
