Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a seedling box take-out device of a seeding device for a seedling box.

(Prior art) In the conventionally known Japanese Patent Application Laid-Open Nos. 61-119519 and 1982-119520, it is possible to supply all or one of bed soil, seeds, covering soil, etc. to a seedling raising box. A motor-driven seedling box stacking device is provided which receives and lowers the seedling boxes sent out one by one to the seedling box take-out side of the transfer table provided with the device and stacks the seedling boxes. It has been proposed that the seedling box stacking device is provided with a transfer and take-out section that automatically transfers the seedling boxes using another motor when a predetermined amount of seedling boxes are stacked next to the device.

(Problem to be solved by the invention) In the known method, when the advance seedling growing box is transferred to the transfer and take-out section, the seedling growing box is taken out and taken to another part, but the work is done in a hurry. There are times when the next seedling box is sent out before it is taken out, and the subsequent seedling box group collides with the stacked seedling box group and collapses.

Therefore, in the present invention, the above structure is improved so that the next seedling growing box is not sent until the seedling growing box is removed.

(Means for Solving the Problems) Therefore, the present invention is based on the seedling box take-out side of the transfer table 1, which is equipped with a device capable of supplying all or any one of bed soil, seeds, covering soil, etc. to the seedling growing box 7. A seedling box stacking device driven by a motor 71 is provided, which receives the seedling boxes 7 sent out one by one and lowers them one by one to stack the seedling boxes 7. When a predetermined amount of seedling boxes 7 are stacked on the stacking device, the motor 7
7, the relationship between the transfer and take-out section 86 and the seedling box stacking device is set as described above before the seven groups of seedling boxes in the transfer and take-out section 86 are taken out.

The switch 81 works in conjunction with the loading/unloading motor 71, and when the switch 81 is turned on, the loading/unloading motor 71 is energized, and the lower rotating shaft 29 and the lower rotating shaft are connected to each other via the bevel gears 66, 67 and bevel gears 68, 69. The shaft 37 is rotated, and the chains 34, 35, 42, and 43 are rotated to lower the seedling box 7. The right receiving frame 44 and the left receiving frame 45 are attached so as not to rotate downward so that they can support the seedling growing box 7. However, it is attached to the chain in a structure that allows it to rotate upward so that it can be folded and raised.

82 is a switch that stops the loading/unloading motor 71 that rotates the right receiving frame 44 and the left receiving frame 45, and the left receiving frame 45 rotates upward to rotate the next right receiving frame 44 and left receiving frame 45. is provided at a position where it comes into contact with the seedling box 7 when it is in a position where it can receive the seedling growing box 7 that is transferred laterally from the transfer table 1 from both sides.

The right receiving frame 44 and the left receiving frame 45 are used to stack the seedling growing boxes 7 one by one, and when n seedling boxes 7 are stacked, no more can be stacked, so they are moved. Therefore,
A switch is provided to detect that n seedling boxes 7 are stacked.

These switches include a switch 83 that turns on when the n-1th seedling box 7 is stacked, and a switch 83 that is turned on when the n-1th seedling box 7 is stacked, and a lower left receiving frame that was in contact with the switch 82 that rises as the n-th seedling box 7 descends. 45 is a switch 84 which detects the nth seedling box 7 provided at a position where it comes into contact when the nth seedling growing box 7 is completely stacked on the receiving ring 23 of the pedestal 22. Switch 83 is n-1
It is provided on the side of the left rear frame pillar 27 so as to be turned on when the second seedling growing box 7 is stacked. The switch 84 is provided above the switch 82 so as to be turned on when the n-th seedling growing box 7 is stacked. When the switches 83 and 84 are turned on at the same time, they communicate this to the transfer motor 77 and operate it.

Accordingly, a transfer/removal portion 86 is provided at the extension portion of the pedestal 22.

A switch 8 is provided in the transfer take-out section 86 and turns on when the seven groups of seedling boxes are transferred from the pedestal 22.
5 will be provided.

When switch 85 is turned on alone,
When only the transfer motor 77 is stopped and the switches 83 and 84 are turned on at the same time, the switch 95 is turned off and the fast-forward motor 61, the loading/unloading motor 71, and the transfer motor 77 are turned on. Then, all seedling box sowing devices such as the bed soil supply device 8, seeding device 9, and covering soil supply device 10 of the transfer table 1 are stopped.

Therefore, a reset switch 96 for restarting the entire device is provided at a desired position, so that the entire device once stopped cannot be restarted unless the reset switch 96 is used.

(effect) Next, we will discuss the effect.

When the seedling growing boxes 7 are fed one after another onto the supply side 5 of the transfer table 1, the seedling growing boxes 7 are transferred by the transfer roll 4, and as they pass below the bedding soil supply device 8, they are supplied with the bedding soil 13. The bed soil 13 is leveled by the bed soil leveling brush 14 and supplied with seeds when passing under the seeding device 9, and after being irrigated by the irrigation device, it is supplied with the covering soil 21 under the covering soil supply device 10. The seeding is thus completed (Figure 1).

Thus, until reaching the take-out side 6 of the transfer table 1, the front end 64 of the succeeding seedling growing box 7 and the rear end 80 of the preceding seedling growing box 7 are connected.
However, when the front end 64 of the seedling raising box 7 reaches the rapid transport roll 52,
Since the fast-forwarding roll 52 is rotating faster than the transfer roll 4, the part indicated by the arrow a separates and moves forward by sliding on the right receiving frame 44 and the left receiving frame 45, and its front end 64 collides with the switch 81 and stops. , rear end 8 of seedling box 7
0 passes through the rapid feed roll 47 and transfers onto the right receiving frame 44 and the left receiving frame 45 (FIG. 9).

When the switch 81 is turned on, the loading/unloading motor 7
1 is turned on and the chains 34, 35, 42, and 43 are rotated, so the right receiving frame 4
4 and the left receiving frame 45 move down with the seedling box 7 placed thereon,
Finally, the seedling growing box 7 reaches above the retaining ring 23.

When the right receiving frame 44 and the left receiving frame 45 descend, they collide with the receiving ring 23 or the stacked seedling growing boxes 7, rotate together like the pulling lugs of a combine harvester, escape upwards, and continue to rotate 180 degrees. The left receiving frame 45 collides with the switch 82, and the switch 82 turns off the loading/unloading motor 71 and stops the rotation of the chains 34, 35, 42, and 43. During this time, the other right receiving frame 44 and left receiving frame 45 are replaced and become ready to receive the seedling raising box 7.

By repeating this operation about n-1 times, n-1 sheets are stacked on the retaining ring 23. Until now, the switches 83 and 84 have not been turned on at the same time, but the n-1 sheets are stacked on the retaining ring 23. When stacked, the switch 83 is turned on for the (n-1)th seedling box 7 (Fig. 10), and in this state, when the next nth seedling box 7 comes into contact with the switch 82, the switch 83 turns on. When the switches 83 and 84 are lowered and completely stacked, another left receiving frame 45 that has been in contact with the switch 82 rises and contacts the switch 84, turning on the switches 83 and 84 at the same time.

When both switches 83 and 84 are turned on, the transfer motor 77 is driven to rotate the shaft 75, which in turn rotates the retaining ring 23 to remove the stacked side-transfer take-out portions 8.
6 (Figure 11).

When the group of seedling raising boxes 7 is transferred to the transfer/retrieval section 86, the front end 64 of the seedling raising boxes 7 turns on the switch 85. At this time, the switch 83 is turned off because the 7 groups of seedling boxes are moved and separated at the same time. Therefore, the switch 85 stops only the transfer motor 77, and the seedling growing boxes 7 transferred from the transfer table 1 are automatically stacked on the pedestal 22.

Normally, the 7 groups of seedling boxes that have been transferred to the transfer/take-out section 86 are immediately taken out from the transfer/take-out section 86 and the above operation is repeated. When the switch 85 is on, the next n-1 sheets are stacked on the pedestal 22 and the switch 83 is turned on (12th
(Fig.), when the next n-th seedling box 7 is stacked,
Switch 83 and switch 84 are turned on simultaneously again (FIG. 12).

However, when switch 85, switch 83, and switch 84 are all turned on, switch 9
5 is cut, and the rapid feed motor 61, the loading/unloading motor 71, the transfer motor 77, and the transfer table 1
Since the sowing device for the seedling box is stopped, transfer table 1
The next seedling raising box 7 is not transferred. Therefore,
This prevents n or more seedling boxes 7 from being stacked on the pedestal 22.

A reset switch 96 for restarting the entire apparatus is provided at a desired position, and the entire apparatus cannot be restarted once it has been stopped unless the reset switch 96 is used. Take out 7 groups of seedling boxes and switch 8
5 is turned off, the entire device does not restart.

Therefore, it is possible to slowly take out the seven groups of seedling boxes in the transfer and take-out section 86 and inspect each part, and when the reset switch 96 is turned on after the inspection, the switch 95 is turned on and the rapid feed motor 61 and the The loading/unloading motor 71 and the seedling box seeding device of the transfer table 1 start working.

At this time, since the loading/unloading motor 71 is stopped while the switches 83 and 84 are turned on at the same time, the 7 groups of seedling boxes on the pedestal 22 are immediately transferred to the transfer/unloading section 86. (Figure 10),
The seedling growing boxes 7 transferred from the transfer table 1 are stacked one after another on the pedestal 22.

Front end 64 of the seedling box 7 transferred to the transfer removal section 86
When the transfer motor 77 hits the switch 85, the transfer motor 77 is cut off and stopped.

(Effects) The present invention provides the seedling growing box 7 which is sent to the seedling box take-out side 6 of the transfer table 1, which is equipped with a device capable of supplying all or any one of bed soil, seeds, covering soil, etc. to the seedling growing box 7. 7 one by one and lower it to raise seedling box 7.
A seedling box stacking device driven by a motor 71 is provided, and when a predetermined amount of seedling boxes 7 are stacked next to the seedling box stacking device, the seedling boxes 7 are automatically transferred by a motor 77. The relationship between the transfer and take-out section 86 and the seedling box stacking device is changed so that the transfer and take-out section 86 is connected to the seedling box stacking device before the seven groups of seedling boxes in the transfer and take-out section 86 are taken out. Since the seedling box take-out device of the seedling box sowing device is configured so that the motor 77 is not driven even when a predetermined amount of seedling boxes 7 are stacked, the preceding seedling box group is transferred to the transfer/take-out section 86. Even if the next seedling growing box is stacked before the seedling growing box group is taken out, the motor 77 is not driven, so that the succeeding seedling growing box group is prevented from colliding with the stacked seedling growing box group and collapsing. Therefore, the work of taking out the seedling growing box 7 can be done relatively slowly, which has the effect of preventing mistakes.
