2. Description of the Related Art As described above, there is a seedling transplanting machine provided with an automatic seedling feeding device for feeding seedlings from a spare seedling storage section to a seedling placing table, as disclosed in Japanese Patent Laid-Open No. 6-125616. In this conventional example, a seedling-containing carrier that is moved downward by driving the chain with claws is provided with a preliminary seedling storage unit that holds the seedlings stored in the carrier in a shelf shape while being locked by the claws of the chain with claws. It is equipped with an automatic seedling supply device that sends the seedlings to the seedling mounting table of the seedling planting device.

[0003]

SUMMARY OF THE INVENTION In this kind of seedling transplanter, seedlings are stored in the spare seedling storage section before the seedlings in the spare seedling storage section are completely consumed so as to prevent the seedlings from being cut off during the work. The work is performed in the form of replenishing. In addition, in this kind of seedling transplanter, the automatic control of supplying seedlings from the spare seedling storage section to the seedling placing table is performed by the automatic seedling feeder.
During this automatic control, the control operation is such that seedlings are taken out from the spare seedling storage unit and supplied to the seedling mounting table in a predetermined order.

Assuming a case of newly supplying seedlings to a spare seedling storage portion in which seedlings remain in the conventional seedling transplantation,
In this conventional example, when replenishing from the outside, the seedlings are lifted by one stage by driving the chain to store the seedlings, and when supplied to the seedling placing table, the seedlings are lowered by one stage by driving the chain to lower the seedlings. I will take the seedlings from
The seedlings that were first sent to that line remain forever,
There is room for improvement as it may be affected by direct sunlight, or drying may damage seedlings.

In the seedling transplanter of this conventional example, the number of parts for holding seedlings in a shelf shape is made to coincide with the number of rows of the seedling placing table, and seedlings are fixed from a certain shelf to a certain planting row. When the seedlings of a specific planting article are consumed quickly, the remaining amount of seedlings of that particular article will drop significantly even if the rate of seedling consumption of other articles is low. Even if there are enough seedlings left in the row, it is necessary to supply seedlings to all the rows in the spare seedling storage section, and there is room for improvement in this respect as well.

An object of the present invention is to supply seedlings to a spare seedling storage section in which the seedlings remain, and then feed the seedlings from the spare seedling storage section to a seedling placing table through an automatic seedling supply device. In this case, the reason is to reasonably configure a seedling transplanter that can preferentially consume the seedlings remaining before the seedlings are replenished.

[0007]

The features of the present invention (Claim 1) are, as mentioned at the beginning, a planting mechanism for a plurality of rows for planting seedlings planted on a seedling platform in a field, and a preliminary seedling. In a seedling transplanter equipped with a seedling automatic feeding device for feeding seedlings from the storage portion to the seedling mounting table, the preliminary seedling storage portion,
It comprises a seedling storage space for storing seedlings in a plurality of rows in the horizontal direction at a plurality of stages in which the seedlings are close to each other in the vertical direction, and the automatic seedling supply device takes out the seedlings held in the seedling storage space. Priority is given to the seedling take-out mechanism that sends the seedlings to the specified row on the seedling placing table and the seedlings remaining in the seedling storage space before the supplementation after the seedlings are supplied to the seedling storage space due to the decrease of the remaining amount of the seedlings in the storage space. And a control means for operating the seedling take-out mechanism in the order of taking out, its action, and
The effects are as follows.

[0008]

According to the above characteristics (Claim 1), when seedlings are supplied to a predetermined row of the seedling mounting table during the seedling planting operation, the seedling removing mechanism takes out the seedlings existing in the seedling storage space, and the predetermined Since the seedlings will be sent to the seedlings, even if the seedlings of a specific row on the seedling loading table are consumed at high speed, the frequency of seedling supply to this specific row only increases, and the remaining amount of seedlings in the spare seedling storage section is supplied. Allows work to continue until required. In addition, after the seedlings have been replenished in the spare seedling storage area due to a drop in the remaining amount of seedlings, the seedling take-out mechanism prioritizes and takes out the seedlings remaining in the seedling storage space before replenishment. Never leave old seedlings in the spare seedling storage area.

That is, unlike the conventional example, seedling replenishment based on the remaining amount of seedlings in the entire spare seedling storage section can be made possible regardless of the seedling consumption rate of a specific row, and the number of times of seedling replenishment can be reduced to improve work efficiency. In addition to the above, it is possible to reduce the damage to the seedlings by shortening the time in which the seedlings are stored in the spare seedling storage unit by controlling the priority order.

According to the second aspect of the present invention, after the seedlings are replenished in the spare seedling storage section, the seedling take-out mechanism starts taking out the seedlings from the row of the side edge on the side where the seedlings remain before the seedlings are replenished. Even if seedlings before replenishment remain in multiple rows of the storage space, these seedlings can be preferentially consumed.

According to the third aspect of the present invention, after the seedlings are supplied to the spare seedling storage section, the seedling take-out mechanism starts to take out the seedlings from the row where the seedlings remain before the seedlings are supplied. Even if the seedlings from before replenishment remain, these seedlings can be preferentially consumed.

According to the fourth aspect, after the seedlings are replenished in the spare seedling storage portion, the takeout member table of the seedling takingout mechanism is provided for the empty space between the replenished seedlings and the seedlings remaining before the replenishment. Insert the seedlings, and then remove the seedlings remaining before the replenishment while placing them on this extraction table.
Since the seedlings that remain before replenishment will be taken out one after another,
Even if seedlings before replenishment remain in multiple rows of the seedling storage space, these seedlings can be consumed with the highest priority.

[0013]

[Effects of the Invention] Therefore, it is possible to lengthen the interval for replenishing seedlings to the spare seedling storage unit to enable highly efficient work, and to replenish the spare seedlings after the seedlings are supplied to the spare seedling storage unit. A rational construction of a seedling transplanter that preferentially consumes the remaining seedlings before the seedlings are replenished when the seedlings are sent from the seedling storage section to the seedling placement table via the automatic seedling feeder. It was done (Claim 1).

In particular, when the seedlings are taken out from the preliminary seedling storage section, the seedlings prior to the seedling supply are preferentially consumed when the seedlings are taken out from the spare seedling storage section by a simple change of the control mode in which the order of taking out the seedlings is changed to the right or left (claim 2). , The seedlings before the seedling supply are preferentially consumed when the seedlings are taken out from the spare seedling storage section by changing the control mode in which the seedlings are taken out from the row where the seedlings before the seedling supply are present (claim 3 ) Moreover, the rational control of the take-out table allows the seedling transplanter which consumes the seedlings remaining before the seedling supply with the highest priority (claim 4).

As shown in the flow chart of FIG. 12, when the control starts, the initial value of the seedling take-out row is set to either left or right (# 101 step), and the remaining amount of seedlings on the seedling placing table 7 is changed as the work progresses. When it drops and the first seedling remaining amount sensor T1 operates to detect (# 102 step), the control device 45 determines the presence or absence of the seedling W in the row from which the seedling W is to be taken out based on the signal from the second sensor S2. (Steps # 103, # 104),
When the seedling W exists, the seedling take-out operation routine (# 1
(Step 05), the take-out table 33 is set at a predetermined position to take out the seedling W, and then the take-out table 33 is taken out under the control of the seedling supply routine (# 106 step).
Is moved to the position of the row of the seedling placement table 7 where the first seedling remaining amount sensor T1 has detected and supplied seedlings, and after this supply, the empty carrier E is controlled by the empty carrier return routine (step # 107). The control to restore the original storage space of the spare seedling storage unit B is performed, and only when the seedlings are replenished to the spare seedling storage unit B, the operation of changing the initial value of the extraction from the spare seedling storage unit B is reset. Until it is done (# 110
# 112 step).

The next row means the seedling W as shown in FIG.
This refers to a row adjacent to the set row (in the direction K in the figure) to be taken out, in which seedlings have not yet been taken out, and the empty space F is ignored.

When the presence of the seedling W is not detected in step # 104, the presence or absence of the seedling W in the next row is determined so as to take out the seedling W from the next row (step # 108). The setting sequence is changed and the control in step # 103 is performed again (step # 109). When the presence of seedlings is not discriminated in step # 108, an alarm operation such as turning on a seedling-out lamp is turned on and the control ends. (Step # 113).

Further, the control in the seedling take-out routine is as follows when the seedling take-out operation is performed from the storage space of the spare seedling storage section B.
Based on the signal from the second sensor S2, the lowest level carrier E in which the seedling W is present is set as the extraction target, the extraction level is determined, and the extraction table 33 is set by driving the first electric motor M1. To the position of
By driving the second electric motor M2, the take-out table 33 is moved to a level at which the carrier E to be taken out can be placed,
By driving the third electric motor M3 and driving the first cylinder C1, the take-out table 33 is inserted below the carrier E to be taken out as shown in FIG. 4, and the pawl 31 is projected by driving the third cylinder C4. After that, the third electric motor M3 and the first cylinder C1 are driven in the opposite direction to complete the removal of the carrier E.

Next, the seedling supply routine is controlled by driving the air cylinders C5 and C6 of the row where the remaining amount of seedlings has dropped to cause the auxiliary base 37 to project and the guide member 38 to expand.
Further, by driving the first electric motor M1 and the second electric motor M2, the take-out table 33 is moved to the position of the row, and the driving of the first electric motor M1 synchronizes with the lateral movement of the seedling placing table 7. By moving the take-out table 33 laterally (control operation is not described in detail), the front portion of the take-out table 33 is lifted by the operation of the second cylinder C2, and the fourth cylinder C4 is moved within a short time. By reciprocating, as shown in FIGS. 5 and 6, the rear end of the inner frame 14 of the carrier E is lifted to the upper edge of the outer frame 13 by contact with the lifting member 35, and the take-out table 33 is placed. As a result of vibrating in the direction along the surface, the mat-shaped seedling W is fed to the seedling placing table 7 along the upper surface of the inner frame 14.
In addition, at the time of work, while supplying the seedling W to a predetermined row,
The first seedling remaining amount sensor T1 and the second seedling remaining amount sensor T2, which are different from each other, may fall into the detection state. In such a case, the second seedling remaining amount sensor T2 is detected with respect to the article. The control for preferentially supplying the seedling W is performed.

Next, in the empty carrier returning routine, after the seedlings have been supplied as described above, the empty carrier E is returned to the original storage space by performing the operation reverse to that described above.

Next, when the remaining amount of the seedlings W in the spare seedling storage section B decreases as the work progresses, the traveling machine body 3 is brought closer to the seedling supply device (not shown) by a predetermined steering control. After that, the conveyor mechanism 42 of the seedling supply device is connected to the seedling supply unit D.
The empty carrier E is taken out by the same control as the above-mentioned taking out of the carrier E, and is placed on the carry-out conveyor 44 of the seedling replenishing section D through the empty space F formed in the center of the spare seedling storage section B. While carrying out the empty carrier E in the state,
A control operation is performed in which the seedling-containing carrier E from the carry-in conveyor 43 is placed on the table 33 and sent to the preliminary seedling storage unit B.

Further, in this rice transplanter, after the seedling W is replenished in the spare seedling storage section B, the above-mentioned # 110, # 11.
As in the 2 step, the seedlings W before this seedling replenishment are preferentially taken out and supplied to the seedling placing table 7 after this replenishment, when seedlings are fed to the seedling placing table 7, as described above. The row on the opposite side of the row from which the W extraction is started, that is, when the first extraction start row NS is the left end row as shown in FIG. 12, after the seedling supply, the right end row The control operation is set to take out the seedling W from NR.

In this way, although the rice transplanter is constructed so that the operator transplants the seedlings without boarding the operator, when the seedling remaining amount on the seedling placing table 7 decreases during the work, the spare seedling storage is performed. The seedlings of the section B can be automatically supplied to the seedling placing table 7 by the automatic seedling supplying device C, and the seedling W of the spare seedling storing section B can be supplied to any row of the seedling placing table T. With this configuration, it is possible to reduce the number of times of seedling replenishment by performing seedling replenishment based on the remaining amount of seedlings in the whole seedling storage unit B, and to prioritize the removal of the seedlings W from the spare seedling storage unit B. By deciding, the seedlings stored earlier are prevented from remaining forever, the damage of the seedlings W is avoided, and the seedlings whose damages are always suppressed can be transplanted.
