DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating grain drying apparatus, and more particularly to a circulating grain drying apparatus in which grains are fed and circulated by a feed valve disposed at a lower part of a grain distribution lower passage.

[0002]

2. Description of the Related Art As shown in FIG.
2 is provided to remove water while the grains naturally flow down the downflow channel 112. This descending road 112
The grain that has flowed down is discharged from the flow-down path 112 alternately downward by the action of a shutter drum (delivery valve) 114 that is disposed below the flow-down path 112 and is reciprocally rotated, and is further discharged from the screw conveyor 116 and the elevator 118. After being transported to the upper part of the device by the transport device, it is sent to the grain tank 110 again. Grains are gradually dried and dried in this circulation.

After the grain drying process is completed, the shutter drum 114, the screw conveyor 116, and the elevator 1
18 to the upper part of the apparatus again.
Is discharged out of the apparatus from a discharge port 120 provided in the upper part of the apparatus.

[0004] The grain discharged out of the apparatus is, for example, packed by a worker as it is or transported and supplied to a hulling machine for hulling. Alternatively, there may be a case where a thrower, a screw transfer device, or the like is attached to the discharge port 120, and further discharge and transfer are performed by these transfer devices.

In the above-described conventional apparatus, when the grain is discharged to the outside of the apparatus after the drying process as described above, the discharge port 120 is opened and the shutter drum 114 is operated by operating the discharge operation switch. Once the grain is fed out of the grain tank 110, the grain is conveyed by the elevator 118 and sequentially discharged from the discharge port 120. However, since the amount of grain discharged from the discharge port 120 is constant, inconvenience and waste occur. There was a case.

That is, for example, when bags of discharged grain are packed in a bag, a discharge gutter (discharge hose or the like) is connected to the discharge port 120 to discharge the cereal with a maximum discharge amount. Or a screw transfer device) for discharge and transfer. In this case, the outlet 120
If the discharge amount from the printer does not correspond to the processing (transport) capacity of the transfer device, for example, if the discharge amount is larger than an appropriate amount according to the processing (transport) capability of the transfer device, the transfer device is clogged. On the other hand, if the discharge amount is smaller than the processing (transport) capacity of the transporter, the processing capacity becomes excessive and the discharge time becomes unnecessarily long, which results in waste. .

[0007] Furthermore, the grain weight per unit volume varies depending on the type of grain. Therefore, as described above, in the case where the transporter is attached to the discharge port 120 to discharge and transport, for example, even if the discharge amount is set corresponding to the paddy, the load (weight) increases when the wheat is discharged. However, the carrier may be clogged as it is, and it is necessary to adjust the inflow amount to the carrier. In this case, since the mounting position (discharge port 120) of the transporter is at a high place, the operation of adjusting the inflow amount is dangerous and complicated. If the amount of discharge from the outlet 120 is larger than the amount of inflow, the excess grain is sent back to the grain tank 110 and recirculated in the apparatus unnecessarily, so that the grain may be damaged. And also consumes wasted power.

[0008]

SUMMARY OF THE INVENTION In view of the above facts, the present invention sets the amount of cereal discharge to an optimum amount according to the work (processing) capacity after discharge, and enables the circulating type cereal to be discharged efficiently. The purpose is to obtain a drying device.

[0009]

A recirculating grain drying apparatus according to the first aspect of the present invention is disposed at a lower portion of a grain distribution lower passage connected to a grain tank, and is a delivery valve for sequentially rotating the grain downward by rotating. And a transport means provided between the delivery valve and the grain tub, for transporting the grain delivered from the delivery valve to the grain tub, and disposed in the middle of a grain transport path by the transport means and opened.

Discharge / conveyance means, discharge type setting means for setting the type of external discharge / conveyance means connected to the discharge port, and the feeding operation based on the setting by the discharge type setting means when the discharge port is open. By automatically controlling the rotation state of the feed amount, the feed amount of the grain of the feed valve, feed amount adjusting means for automatically adjusting to a preset amount according to the type of the external discharge conveying means connected to the discharge port, It is characterized by having.

[0010] In the circulating grain drying apparatus having the above structure, at the time of discharging the grain, the delivery valve and the conveying means are operated to sequentially feed the grains in the grain tank to the discharge port, and the discharge port is opened. Thereby, the grain sent to the discharge port is discharged and conveyed out of the apparatus by an external discharge conveyance means (for example, a discharge gutter such as a discharge hose, a transfer device such as a thrower or a screw transfer device) connected to the discharge port. You.

Here, the amount of grain sent from the grain tank to the discharge port in the apparatus depends on the rotation state of the delivery valve. In other words, if the amount of feed is increased by changing the rotation state of the feed valve, the amount of grain sent to the discharge port, that is, the amount of discharge, will increase.If the amount of feed of the feed valve is reduced, the amount of discharge from the discharge port will decrease. Is done. Further, the rotation state of the delivery valve is determined according to the type of the external discharge / conveying means connected to the discharge port based on the setting by the discharge type setting means (that is, which type of external discharge / conveying means is connected). The amount is automatically controlled and changed by the feeding amount adjusting means so that the amount is set in advance.

That is, the rotation state of the delivery valve is automatically adjusted by the delivery amount adjusting means so as to be an optimum discharge amount according to the type of the external discharge / conveying means.

[0013] Thus, for example, in the case of connecting the discharge gutter to the discharge port as an external discharge conveying means and packing the discharged grains in a bag, the discharge amount is set to be the maximum so that the discharge can be efficiently performed. can do. On the other hand, when the transfer device is connected to the discharge port for discharge and transfer as an external discharge transfer device, if the discharge amount is set in accordance with the processing (transport) capacity of the transfer device, the appropriate amount can be set. It is automatically adjusted so that the transporter does not become jammed or drains unnecessarily long.

Thus, the circulation type grain drying apparatus according to the first aspect can efficiently discharge the grain by setting the quantity of the grain discharged to an optimum amount according to the work (processing) capacity after the discharge.

The rotation state of the delivery valve can be changed by increasing or decreasing the rotation cycle of the delivery valve or increasing or decreasing the rotation speed of the delivery valve. Thereby, the amount of discharged grains can be changed.

The discharge type setting means can be constituted by a discharge type setting dial provided on the operation panel of the apparatus. Thereby, the type of the external discharge conveyance means connected to the discharge port can be set, and the rotation amount of the delivery valve can be changed to optimize the discharge amount of the grain.

According to a second aspect of the present invention, there is provided a circulating grain drying apparatus according to the first aspect, further comprising grain setting means for setting a type of grain discharged from the grain tank to the outside of the apparatus. The feed amount adjusting means automatically adjusts a grain feed amount of the feed valve to a preset amount according to a grain type set by the grain setting means.

In the circulating grain drying apparatus having the above structure, the type of grain discharged from the grain tank to the outside of the apparatus (eg, paddy or wheat).
Is set by the grain setting means. Furthermore, the amount of grain delivered from the delivery valve (in other words, the rotation state of the delivery valve) is
The amount is automatically controlled and changed by the feeding amount adjusting means so that the amount is set in advance according to the grain type set by the grain setting means.

That is, even when different types of grains are processed, the rotation state of the delivery valve is changed according to the type of each grain, and the amount of the discharged grains is automatically adjusted so as to be the optimum amount. Is adjusted to

Thus, for example, when the transporter is connected to the discharge port as an external discharge and transport means to discharge and transport the paddy from the grain tank to the outside of the apparatus, the feed amount of the feed valve is increased. However, in the case of wheat, if the feed amount of the grain of the feed valve is set to be small, it is automatically adjusted to this appropriate amount, and the transporter is not clogged and the discharge time does not become unnecessarily long .

As described above, the circulating grain drying apparatus according to the second aspect of the present invention can not only adjust the amount of discharged grains to the work (processing) capacity after the discharge, but also optimize the amount of the discharged grains in accordance with the type of the discharged grains. It is possible to set and discharge efficiently.

The grain setting means can be constituted by a grain switching dial provided on the operation panel of the apparatus and capable of switching the grain type. Thereby, the type of each grain can be set by the grain switching dial, and the rotation state of the delivery valve according to the type of grain is changed, so that the amount of the grain discharged automatically becomes the optimum amount of discharge. Can be adjusted.

In addition to the drive operation of the separator 60), the burner 66 and the suction exhaust fan 70 can be driven, and the discharge shutter 74 can be opened during the discharge operation (when the discharge switch is operated).

The setting dial section 98 is provided with a discharge type setting dial 106 as discharge type setting means, a grain switching dial 100 as a grain setting means, a grain amount setting dial 102, and a moisture setting dial 104. .

The discharge type setting dial 106 can set the type of the transport means connected to the grain discharge port 72 (either the discharge hose 76 or the thrower 108) by dial operation. Further, the amount of grain fed from the shutter drum 50 is set in accordance with the type of the conveying means set by the discharge type setting dial 106.

The grain switching dial 100 can be set to paddy or wheat according to the type of grain to be dried (that is, to be discharged, of course). Drying prevention control is automatically performed.

Further, according to the kind of grain set by the grain switching dial 100, the shutter drum 5
The amount of grain fed from 0 is set. Thus, when the discharge operation is performed (that is, in a state where the discharge switch is operated and the discharge shutter 74 is opened), the operation panel 88 is provided on the operation panel 88 according to the type of the grain set by the grain switching dial 100. Control circuit (C

In this embodiment, when the grain to be discharged is paddy in a state where the thrower 108 is connected to the grain discharge port 72, the rotation cycle of the shutter drum 50 is 13 seconds (rotation time). Is 12 seconds, pause time is 1 second,
Discharge amount is large), and when the discharged grain is wheat, the rotation cycle of the shutter drum 50 is set to 1
5 seconds (rotation time is 12 seconds, pause time is 3 seconds, discharge amount is small). On the other hand, in a state where the discharge hose 76 is connected to the cereal discharge port 72, the rotation cycle of the shutter drum 50 is 13 seconds (the rotation time is 12 seconds, Is one second,
Emissions are high).

In this case, with the discharge hose 76 connected to the cereal discharge port 72, the rotation cycle of the shutter drum 50 may be different depending on whether the cereal to be discharged is paddy or wheat. Of course it is good. Further, the present invention is not limited to changing the rotation cycle of the shutter drum 50 as described above.

It is also possible to change the rotation speed of 0 (fast or slow).

On the other hand, the cereal amount setting dial 102 adjusts the dial scale to the cereal amount that has been stuck,
An appropriate hot air temperature is set based on the outside air temperature and the amount of grains at that time. Further, the moisture setting dial 104 automatically stops the apparatus when the moisture value of the grain becomes equal to or less than the set finish moisture value by matching the target moisture value during the drying operation. You can do it.

Next, the operation of the circulating grain drying apparatus 10 having the above configuration will be described. The lower screw conveyor 54 of the circulating system of the circulating grain drying apparatus 10 for inserting the grain,
The elevator 56, the upper screw conveyor 58, and the rotary equalizer 60 are driven. Then, the hopper 62 on the lower side of the circulating grain drying apparatus 10 is opened to release the grain from the airframe 1.
2 The loaded grain is guided by the loading sink 52 and transported to the position where the lower screw conveyor 54 is provided. The transported grain is sequentially transported to the elevator 56 side by the lower screw conveyor 54, and further scooped up and transported by the bucket 57 of the rotating elevator 56.

The grain lifted and conveyed above the machine body 12 by the elevator 56 is sent to the upper central portion of the machine body 12 by the upper screw conveyor 58 and stored in the grain tank 24 in the machine body by the rotary type equalizer 60. In this case, since the discharge shutter 74 is closed and the grain discharge port 72 is in the closed state, the grains lifted and transported by the elevator 56 are not discharged from the grain discharge port 72 to the outside of the apparatus.

Here, after the end of the setting, the shutter drum 50 is rotated to feed out the grain. Then, the burner 66 connected to the body 12 is ignited, and
Is driven, the drying air is sucked by the suction exhaust fan 70 and sent to the air guide passage 38 via the air guide communication passage 64. The drying air sent into the air guide passage 38 passes through the air guide passage partition wall 34,
It is supplied directly to the grains in the downflow channel 46. Here, the grain is dried. The drying air after absorbing the moisture of the grain passes through the exhaust air passage partition wall 28, reaches the exhaust air communication passage 68 via the exhaust air passage 32, and is discharged out of the circulation type grain drying device 10.

On the other hand, the grains in the downflow path 46 pass through the outflow port 48 by the rotation of the shutter drum 50 and are guided and conveyed again by the filling plate 52. The conveyed grain repeats the above-described circulating action in the machine body 12 as needed until the desired moisture content is reached.

After the drying process is completed, a grain discharging process is performed. In other words, the discharge shutter 74 is opened and moved by operating the discharge switch of the operation panel 88 to move the grain discharge port 7.
2 is opened. The grain that has flowed down the downflow path 46 flows into the shutter drum 50 and is fed downward by the operation of the shutter drum 50, and the lower screw conveyor 54
Sent to The grain discharged from the shutter drum 50 and sent to the lower screw conveyor 54 is again lifted and conveyed by the elevator 56, and then the grain outlet 72
From the device.

The cereal discharged from the cereal discharge port 72 to the outside of the apparatus is transported by a conveying means (for example, a discharge hose 76 as shown in FIG. 1 or a thrower 108 as shown in FIG. 2) connected to the cereal discharge port 72. It is further discharged and conveyed.

Here, the type of the transport means connected to the grain discharge port 72 as described above is determined by the discharge type setting dial 106 provided on the operation panel 88 (the discharge hose 76 or the thrower 108). Is set. Further, the type of grain (eg, paddy or wheat) discharged from the grain tank 24 to the outside of the apparatus is determined by the grain switching dial 10.
Set by 0.

Here, the grain tank 24 in the apparatus
The amount of cereal sent from the hopper to the cereal discharge port 72 depends on the rotation state of the shutter drum 50. That is, if the rotation state (rotation cycle or rotation speed) of the shutter drum 50 is changed to increase the feeding amount, the amount of grain sent to the grain discharge port 72, that is, the discharge amount, also increases.
If the feed amount of 0 is reduced, the discharge amount from the grain discharge port 72 is also reduced. Further, the rotation state of the shutter drum 50 is determined by the type of the transporting means set by the discharge type setting dial 106 (that is, which type of transporting means is connected to the grain discharge port 72), and the grain switching dial 100. Based on the set grain type, the amount is automatically controlled and changed to a preset amount.

That is, the rotation state (rotation cycle or rotation speed) of the shutter drum 50 is controlled by the control circuit (CPU) provided on the operation panel 88 to determine the type of the conveying means connected to the grain discharge port 72 and the grain to be discharged. It is automatically adjusted so as to obtain the optimal discharge amount according to the type of the slag.

For example, in this embodiment, when the grain to be discharged is paddy in a state where the thrower 108 is connected to the grain discharge port 72, the discharge type setting dial 10 is used.
6 with the “transporter” and the grain switching dial 1
When 00 is set to "paddy", the rotation cycle of the shutter drum 50 is 13 seconds (the rotation time is 12 seconds, and the pause time is 1 second)
On the other hand, if the grain to be discharged is wheat, setting the grain switching dial 100 to “wheat” causes the rotation cycle of the shutter drum 50 to be 15 seconds (the rotation time is 12 seconds, The time is controlled to be 3 seconds). On the other hand, in a state where the discharge hose 76 is connected to the grain discharge port 72, if the discharge type setting dial 106 is set to “discharge gutter”, the discharged grain is either paddy or wheat (the grain switching dial 100). Is controlled so that the rotation cycle of the shutter drum 50 is 13 seconds (rotation time is 12 seconds and pause time is 1 second).

For example, as shown in FIG. 1, when the discharge hose 76 is connected to the cereal discharge port 72 as a conveying means and the discharged cereal is bagged, the discharge amount is maximized and the effluent is maximized. Can be discharged.

On the other hand, for example, as shown in FIG. 2, even when a thrower 108 is attached as a conveying means to the grain discharge port 72 of the circulating grain drying apparatus 10 and discharged and conveyed by the thrower 108, The amount is automatically adjusted to an appropriate amount corresponding to the processing (transporting) capacity of the thrower 108, so that the thrower 108 is not clogged or the discharge time does not become unnecessarily long.

As described above, the circulating grain drying apparatus 10 according to the present embodiment can not only correspond to the working capacity after discharging (processing capacity of the conveying means) but also the type of the discharged grain. It is possible to set the optimum amount according to and discharge efficiently.

In the above embodiment, the rotation state (rotation cycle or rotation speed) of the shutter drum 50 is controlled by a control circuit (CPU) provided on the operation panel 88.
The configuration in which the discharge amount is adjusted according to the type (discharge hose 76 or thrower 108) of the conveyance means connected to the grain discharge port 72 has been described. Other carriers, such as carriers, can also be connected. Therefore, in this case, the discharge amount may be set and adjusted for each transport means so that the discharge amount corresponds to the type of each transport means connected to the grain discharge port 72.

For example, as shown in an operation panel 88 shown in FIG. 6, a discharge type setting dial 107 as a discharge type setting means may be provided in place of the discharge type setting dial 106. The discharge type setting dial 107 is provided with dial scales of “discharge gutter”, “thrower”, and “screw”. In the case of the discharge hose 76 (when the dial scale is set to “discharge gutter”), The discharge amount was set to a large amount, and in the case of the thrower 108 (when the dial scale was set to the “thrower”), the discharge amount was set to a medium amount. In the case of the screw transporter (the dial scale was set to the “screw”) Case), the discharge amount can be set to a small amount. As a result, the amount is automatically adjusted to an appropriate amount corresponding to the processing (transport) capacity of each transport unit, and the discharge can be performed efficiently.

Further, in the above-described embodiment, the rotation state (rotation cycle or rotation speed) of the shutter drum 50 is connected to the grain discharge port 72 by a control circuit (CPU) provided on the operation panel 88. Although the type is automatically adjusted so as to be a preset optimal discharge amount based on the type of transport means and the type of grain to be discharged, individual types of transport means or individual types of grain to be discharged are set. It is also possible to make fine adjustments to the emissions individually for each type.

For example, the discharge type setting dial 106, 1
07 or stepwise fine adjustment in accordance with the position of the indication line of the grain switching dial 100, for example, absorbs the variation in the processing capacity of the individual transport means (correction).
And can be adjusted according to the skill of the worker, and the discharge can be performed even more efficiently.
